Methods: The study was conducted to collect 138 patients taking icotinib hydrochloride with advanced non-small cell lung cancer in hospitals of Dalian (China) from September 1st 2011 to June 14th 2012. All patients had taken icotinib hydrochloride (125 mg three times a day) until the disease was progressed or the adverse reactions could not be tolerated. During the period of taking it, other anti-tumor treatments were forbidden. We observed the symptoms, such as cough, short breath, hemoptysis, pain. The objective efficacy was evaluated by RECIST criteria, and the adverse reactions related to the treatment was assessed on the basis of NCl-CTC 3.0. Results: Of all patients, CR was 1 (0.7%), PR was 59 (42.8%), SD was 37 (26.8%), PD was 41 (29.7%). And ORR was 43.5% (60/138), DCR 70.3% (97/138). The DCR of females was 83.5% (71/85) versus 49.1% (26/53) of males. The difference of ORR and DCR between the two subgroups had statistical significance (X2 = 8.065, P = 0.05; X2 = 18.577, P = 0.000). The difference of ORR and DCR between the subgroups of patients after or before 70 years old had no statistical significance. The difference of ORR and DCR between the subgroups of smoking and non-smoking had statistical significance (X2 = 8.492; X2 = 13.602). The difference of ORR and DCR between the CEA subgroups had statistical significance (X2 = 14.141; X2 = 14.160), showed 81 patients with abnormal CEA before the treatment with ORR 56.8.0% (46/81), DCR 81.5% (66/81); 57 patients of normal CEA before the treatment with ORR 24.6% (14/57), DCR 52.6% (30/57). The 36 patients (26.1%) using icotinib hydrochloride as the first-line treatment, 78 patients (56.5%) using icotinib hydrochloride as the second-line, 20 patients (14.5%) using icotinib hydrochloride as the third-line, and 4 patients (2.9%) with tyrosine kinase inhibitor (TKI) resistance, there was statistical difference of DCR among the multi-groups above (~2 = 11.734, P = 0.008). ORR was 31.1% (14/45) versus DCR 53.3% (24/45) in 45 patients with PS 3-4 points, and ORR was 49.4% (46/93) versus DCR 78.5% (73/93) in 93 patients with PS 0-2 points, and there was statistical difference (X2 = 4.156; X2 = 9.149). The main adverse reactions were rash (26.8%), diarrhea (13.8%), mild liver function abnormal (10.9%). Conclusion: The short-term efficacy of icotinib hydrochloride on the treatment of advanced NSCLC is positive, and the relevant adverse reactions are mild. The efficacy is better when the patient is female, non-smoker, treated as first-line, with higher CEA before treatment and lower PS scores.展开更多

The age of onset of gastric cancer is in line with the general rule of cancer. Most of them occur after middle age, mostly between 40and 60 years old, with an average age of about 50 years old, and only 5% of patients are under 30 years old. The incidence of male is higher than that of female.AIM To investigate the short-term efficacy and influencing factors of chemotherapy combined with irinotecan in patients with advanced gastric cancer.METHODS Eighty patients with advanced gastric cancer who were treated in our hospital from January 2019 to January 2022 were selected. The patients were divided into an observation group(n = 40) and control group(n = 40) by the envelope method.The control group was given preoperative routine chemotherapy. The observation group was treated with irinotecan in addition to the chemotherapy given to the control group. The short-term efficacy of treatment in the two groups, as well as tumor marker levels and quality of life before and after treatment were evaluated.RESULTS The short-term treatment effect in the observation group was better than that in the control group(P < 0.05), and the total effective rate was 57.50%. The age and proportion of tumor node metastasis(TNM) stage IV patients with ineffective chemotherapy in the observation group were(65.12 ± 5.71) years and 52.94%,respectively, which were notably higher than those of patients with effective chemotherapy(P < 0.05), while the Karnofsky Performance Scale score was(67.70± 3.83) points, which was apparently lower than that of patients with effective chemotherapy(P <0.05). After 3 mo of treatment, the SF-36 scale scores of physiological function, energy, emotional function, and mental health in the observation group were 65.12 ± 8.14, 54.76 ± 6.70, 47.58 ± 7.22,and 66.16 ± 8.11 points, respectively, which were considerably higher than those in the control group(P < 0.05). The incidence rates of grade Ⅲ-Ⅳ diarrhea and grade Ⅲ-Ⅳ thrombocytopenia in the observation group were 32.50% and 25.00%, respectively, which were markedly higher than those in the control group(P < 0.05).CONCLUSION Chemotherapy combined with irinotecan in patients with advanced gastric cancer has a good short-term efficacy and can significantly reduce serum tumor markers and improve the quality of life of patients. The efficacy may be affected by the age and TNM stage of the patients, and its long-term efficacy needs further study.展开更多

To bridge the knowledge gap,we did a meta-analysis to assess the efficacy of ≤6 months versus ≥12 months DAPT among patients with second-generation drug-eluting stents. Methods We searched online databases and identified randomized controlled trials that assess the clinical impact of short-term DAPT(≤6 months) published before March 3,2016. The efficacy endpoints included the incidence of all-cause death,myocardial infarction,cerebrovascular accidents,and definite or probable stent thrombosis. Safety endpoint defined as major bleeding was also evaluated and discussed. Results We included 5 trials that randomized 9473 participants(49.8%,short-term DAPT duration vs. 50.2%,standard duration). A total of 9445(99.7%) patients reported the efficacy endpoints,and the safety endpoint was available from 4 studies(n=8457). There was no significant difference in efficacy endpoints between short-term and standard DAPT duration(≥12 months) [risk ratio(RR) 0.96; 95% confidence intervals(CI),0.80-1.15]. Short-term DAPT duration did not significantly increase the individual risk of all-cause death,myocardial infarction,cerebrovascular accidents,or definite or probable stent thrombosis. Although short-term DAPT obviously reduced risk of major bleeding compared with standard DAPT(RR 0.53; 95% CI,0.29-0.96),significant publication bias was found when accessing the safety endpoint of the 4 studies(Egger's test,P=0.009). Conclusions The efficacy of short-term DAPT was comparable with that of standard duration DAPT.DAPT less than 6 months may be appropriate for patients receiving second-generation drug-eluting stents implantation.展开更多

There are no ideal indicators forecasting surgical results before operation. The surface enhanced laser desorption ionization-time of flight-mass spectroscopy (SELDI-TOF-MS) is a currently new technique for detection of protein profiles, and some progresses have been made in cancer diagnosis and efficacy evaluation, but there is no report on efficacy forecasting of MG surgery. This study aimed to establish an efficacy prognosis model for forecasting the efficacy of surgery for MG by analysis of serum protein profiles of MG patients before surgery. Methods Fifty-six MG patients 6 months after extended thymectomy were enrolled in the study. They were classified into effective or non-effective groups according to symptoms and medication. Their pre-operative blood samples were analyzed for protein profiles by the SELDI-TOF MS technique, and protein peaks were identified for establishment of the efficacy prognosis model of MG surgery. Additional 100 MG patients were subjected to model validation and their pre-operation protein profiles reviewed for post-operative results. The results were compared with those of the post-operative follow-up so as to validate the prognosis model. Results For the model establishment, symptoms were improved in 33 patients and not improved in 18 patients, with an effective rate of 64.7%. Five (8.9%) patients were lost to follow-up. Within the molecular weight range of 1 000 to 20 000, 3 specific protein peaks were found to be significantly different between the effective and non-effective groups, ie M4110-76, M3394-58, and M1258-55. Using the efficacy prognosis model constructed with these data, the accuracy rate of classification was 87.9% for the effective group, and 83.3% for the non-effective group, with a total accuracy rate of 86.3%. For the model evaluation, 2 (8.9%) patients were lost to follow-up, 62 patients were effective and 36 were non- effective. By comparing with the real results of follow-up with 65 effective and 33 non-effective patients with an effective rate of 66.3%, the accuracy rate of prediction by the prognosis model was 86.2% for the effective group, and was 81.8% for the non-effective group with a total accuracy rate of 84.5%. Conclusions By protein profiles analysis of pre-operative blood samples taken from MG patients with the SELDI-TOF MS technique, protein peaks correlated with surgery efficacy in MG patients can be found for primary forecasting short-term efficacy of surgery for MG patients.展开更多

However, few studies of cetuximab on patients with noncolorectal gastrointestinal cancer were available now. The aim of this study was to summarize the efficacy and safety profiles base-on the experiences of 16 patients with noncolorectal gastrointestinal cancer accepted cetuximab-contained regimens treatment. Methods: The clinical data of all patients with noncolorectal gastrointestinal cancer treated by cetuximab combined with chemotherapy and/or radiotherapy from October 1st 2006 to Jun 30th 2009 in Sun Yat-sen University Cancer Center were collected. Results: (1) A total of 16 patients enrolled, including gastric cancer, esophageal carcinoma, pancreatic cancer and cholangiocarcinoma (8, 6, 1 and 1, respectively). The cetuximab was administered 92 cycles totally with median cycle of 4. (2) PR, SD and PD obtained in 4, 3 and 2 patients respectively in cetuximab + chemotherapy group. The disease control rate, median l-rP and median OS were 77.8% (7/9), 3.5 months and 3.5 months, respectively. (3) Both of patients in cetuximab + radiotherapy group achieved PR with median TTP of 4 months and 7 months, with median OS of 14 and 28 months, respectively. (4) in evaluable patients, 3 PR obtained in first-line setting, 1 PD and 1 SD achieved in second-line setting, 2 SD and 1 PD appeared in third-line and more than third-line setting. (5) The commonly side effect was neutropenia, however, rash and hypomagnesemia were the common side effects related to cetuximab. Conclusion: Cetuximab-contained regimens show a promising disease control rate, especially in first-line setting, in patients with noncolorectal gastrointestinal cancer, and the side effects both related to cytotoxic agents and related to cetuximab itself is tolerable and manageable. Of course, more phase Ⅲ clinical trails are needed urgently.展开更多

文摘Objective: The aim of the study was, (1) to observe the short-term efficacy and adverse reactions of icotinib hydrochloride on the treatment of advanced non-small cell lung cancer (NSCLC); (2) to explore whether there is difference in the efficacy of icotinib hydrochloride among the subgroups of sex, age, smoking history, classification of CEA, histological type, multi-line treatment and PS score. Methods: The study was conducted to collect 138 patients taking icotinib hydrochloride with advanced non-small cell lung cancer in hospitals of Dalian (China) from September 1st 2011 to June 14th 2012. All patients had taken icotinib hydrochloride (125 mg three times a day) until the disease was progressed or the adverse reactions could not be tolerated. During the period of taking it, other anti-tumor treatments were forbidden. We observed the symptoms, such as cough, short breath, hemoptysis, pain. The objective efficacy was evaluated by RECIST criteria, and the adverse reactions related to the treatment was assessed on the basis of NCl-CTC 3.0. Results: Of all patients, CR was 1 (0.7%), PR was 59 (42.8%), SD was 37 (26.8%), PD was 41 (29.7%). And ORR was 43.5% (60/138), DCR 70.3% (97/138). The DCR of females was 83.5% (71/85) versus 49.1% (26/53) of males. The difference of ORR and DCR between the two subgroups had statistical significance (X2 = 8.065, P = 0.05; X2 = 18.577, P = 0.000). The difference of ORR and DCR between the subgroups of patients after or before 70 years old had no statistical significance. The difference of ORR and DCR between the subgroups of smoking and non-smoking had statistical significance (X2 = 8.492; X2 = 13.602). The difference of ORR and DCR between the CEA subgroups had statistical significance (X2 = 14.141; X2 = 14.160), showed 81 patients with abnormal CEA before the treatment with ORR 56.8.0% (46/81), DCR 81.5% (66/81); 57 patients of normal CEA before the treatment with ORR 24.6% (14/57), DCR 52.6% (30/57). The 36 patients (26.1%) using icotinib hydrochloride as the first-line treatment, 78 patients (56.5%) using icotinib hydrochloride as the second-line, 20 patients (14.5%) using icotinib hydrochloride as the third-line, and 4 patients (2.9%) with tyrosine kinase inhibitor (TKI) resistance, there was statistical difference of DCR among the multi-groups above (~2 = 11.734, P = 0.008). ORR was 31.1% (14/45) versus DCR 53.3% (24/45) in 45 patients with PS 3-4 points, and ORR was 49.4% (46/93) versus DCR 78.5% (73/93) in 93 patients with PS 0-2 points, and there was statistical difference (X2 = 4.156; X2 = 9.149). The main adverse reactions were rash (26.8%), diarrhea (13.8%), mild liver function abnormal (10.9%). Conclusion: The short-term efficacy of icotinib hydrochloride on the treatment of advanced NSCLC is positive, and the relevant adverse reactions are mild. The efficacy is better when the patient is female, non-smoker, treated as first-line, with higher CEA before treatment and lower PS scores.
文摘BACKGROUND Hepatectomy is the first choice for treating liver cancer.However,inflammatory factors,released in response to pain stimulation,may suppress perioperative immune function and affect the prognosis of patients undergoing hepatectomies.AIM To determine the short-term efficacy of microwave ablation in the treatment of liver cancer and its effect on immune function.METHODS Clinical data from patients with liver cancer admitted to Suzhou Ninth People’s Hospital from January 2020 to December 2023 were retrospectively analyzed.Thirty-five patients underwent laparoscopic hepatectomy for liver cancer(liver cancer resection group)and 35 patients underwent medical image-guided microwave ablation(liver cancer ablation group).The short-term efficacy,complications,liver function,and immune function indices before and after treatment were compared between the two groups.RESULTS One month after treatment,19 patients experienced complete remission(CR),8 patients experienced partial remission(PR),6 patients experienced stable disease(SD),and 2 patients experienced disease progression(PD)in the liver cancer resection group.In the liver cancer ablation group,21 patients experienced CR,9 patients experienced PR,3 patients experienced SD,and 2 patients experienced PD.No significant differences in efficacy and complications were detected between the liver cancer ablation and liver cancer resection groups(P>0.05).After treatment,total bilirubin(41.24±7.35 vs 49.18±8.64μmol/L,P<0.001),alanine aminotransferase(30.85±6.23 vs 42.32±7.56 U/L,P<0.001),CD4+(43.95±5.72 vs 35.27±5.56,P<0.001),CD8+(20.38±3.91 vs 22.75±4.62,P<0.001),and CD4+/CD8+(2.16±0.39 vs 1.55±0.32,P<0.001)were significantly different between the liver cancer ablation and liver cancer resection groups.CONCLUSION The short-term efficacy and safety of microwave ablation and laparoscopic surgery for the treatment of liver cancer are similar,but liver function recovers quickly after microwave ablation,and microwave ablation may enhance immune function.
文摘BACKGROUND Flat bone metastases are common in patients with advanced cancers,often resulting in severe pain,limited mobility,and reduced quality of life(QOL).Traditional treatment options,such as radiotherapy or systemic therapies,often fail to provide sufficient pain relief or improve functional outcomes in these patients.Microwave ablation(MWA)offers advantages,such as shorter pro-cedure times and larger ablation zones,while percutaneous osteoplasty(PO)enhances bone stability and prevents pathological fractures.Despite these be-nefits,the combination of these techniques for treating flat bone metastases re-mains underexplored.AIM To evaluate the efficacy and safety of C-arm computed tomography(CT)-guided MWA combined with PO for managing painful flat bone metastases,focusing on pain relief,functional improvement,and QOL enhancement.METHODS A total of 45 patients with refractory moderate-to-severe pain resulting from flat bone metastases who underwent C-arm CT-guided MWA combined with PO between January 2015 and January 2021 were included.The efficacy of the pro-cedure was assessed by changes in the visual analog scale(VAS),Oswestry disability index(ODI),and QOL,as well as the occurrence of complications.Tumor response was evaluated using RECIST v1.1 and mRECIST criteria,with overall response rate(ORR)and disease control rate(DCR)as the primary end-points.RESULTS No serious complications were observed in any of the patients.A significant reduction in VAS and ODI was noted at 1 week,1 month,and 3 months post-procedure.A marked improvement in QOL was observed at all follow-up points.Bone cement extravasation was observed in 10 patients;however,none exhibited significant clinical symptoms.Based on RECIST v1.1,the ORR was 26.7%and the DCR was 88.9%.The mRECIST evaluation revealed a higher ORR of 51.1%and DCR of 88.9%.CONCLUSION C-arm CT-guided MWA with PO provides a dependable and effective strategy for managing flat bone metastases.It demonstrates significant pain relief,improved functional outcomes,and enhanced QOL.This treatment combination also shows promising tumor response rates with a low complication profile.
文摘BACKGROUND Kidney dysfunction and reduced filtration capacity due to chronic kidney disease(CKD)lead to a shift in the body's acid-base balance,ultimately causing metabolic acidosis(MA).Sodium bicarbonate has been used as a supplement to alleviate the symptoms and reverse the acidosis,and it may even slow the progression of CKD.However,its safety profile and overall effectiveness are uncertain.AIM To conduct a systematic review and meta-analysis of clinical trials assessing sodium bicarbonate's safety and efficacy for treating CKD-induced MA.METHODS Medline,Scopus,EMBASE,and Cochrane Central were systematically searched from inception until May 2024 to select all relevant randomized control trials(RCTs)and non-RCT(NRCTs)evaluating the effectiveness of sodium bicarbonate in correcting MA in end-stage renal disease patients.In addition,ClinicalTrials.gov,Medrxiv.org,and Google Scholar were searched for other literature.A random-effects meta-analysis was performed to derive mean differences(MD)and risk ratios(RR)with their 95%CI for continuous and dichotomous outcomes respectively.RESULTS Following a systematic search of the databases,20 RCTs and 2 and NRCTs comprising 2932 patients were included in our study.The results revealed that sodium bicarbonate significantly increased serum bicarbonate in CKD patients(MD:2.59,95%CI:0.95-4.22;P=0.02;I2=95%).However,there was a non-significant increase in estimated glomerular filtration rate(eGFR)in patients on sodium bicarbonate therapy(MD:0.93,95%CI:-1.88-3.75;P=0.52;I2=93%).Upon assessment of the safety profile of sodium bicarbonate,no significant association was found in the outcomes of death/prolonged hospitalization(RR:1.05,95%CI:0.84-1.32;P=0.66;I2=0%),or gastrointestinal disorders(RR:1.64,95%CI:0.35-7.66;P=0.53;I2=76%),or worsening edema(RR:1.26,95%CI:0.94-1.68;P=0.12;I2=37%)when compared to control.CONCLUSION Sodium bicarbonate therapy may halt worsening kidney function by correcting serum bicarbonate levels and treating MA.Although sodium bicarbonate does not significantly improve the eGFR,it may potentially prevent CKD progression while maintaining an overall favorable safety profile.
文摘BACKGROUND Colorectal cancer(CRC)is a leading cause of cancer-related mortality worldwide.In cases of metastatic CRC(mCRC)that are resistant to conventional chemo-therapy-based treatments,the efficacy of available therapeutic options is typically low.CRC exhibiting overexpression or amplification of the human epidermal growth factor receptor 2(HER2)gene has shown responsiveness to HER2-targeted therapies.CASE SUMMARY We present the case of a 69-year-old woman diagnosed with mCRC with an NRAS p.G12V mutation and microsatellite stability,identified through tumor sequencing,along with HER2 overexpression detected by immunohistochemistry.She exhibited an excellent response to disitamab vedotin-containing therapy.To our knowledge,this is the first reported case of mCRC with HER2 overexpression and an NRAS p.G12V mutation achieving a remarkable clinical response to anti-HER2 therapy.CONCLUSION Disitamab vedotin demonstrates promising anti-tumor effects in HER2-overex-pressing mCRC,offering patients an additional treatment option.

文摘The remaining useful life prediction of rolling bearing is vital in safety and reliability guarantee.In engineering scenarios,only a small amount of bearing performance degradation data can be obtained through accelerated life testing.In the absence of lifetime data,the hidden long-term correlation between performance degradation data is challenging to mine effectively,which is the main factor that restricts the prediction precision and engineering application of the residual life prediction method.To address this problem,a novel method based on the multi-layer perception neural network and bidirectional long short-term memory network is proposed.Firstly,a nonlinear health indicator(HI)calculation method based on kernel principal component analysis(KPCA)and exponential weighted moving average(EWMA)is designed.Then,using the raw vibration data and HI,a multi-layer perceptron(MLP)neural network is trained to further calculate the HI of the online bearing in real time.Furthermore,The bidirectional long short-term memory model(BiLSTM)optimized by particle swarm optimization(PSO)is used to mine the time series features of HI and predict the remaining service life.Performance verification experiments and comparative experiments are carried out on the XJTU-SY bearing open dataset.The research results indicate that this method has an excellent ability to predict future HI and remaining life.
文摘AIM:To investigate the short-term benefits of laparoscopic radical gastrectomy(LARG)and open radical gastrectomy(ORG)in patients with gastric cancer.METHODS:A total of 400 patients with gastric cancer aged≤65 years who were treated at General Hospital of Lanzhou Military Region were enrolled.Among these,200 patients underwent LARG between October2008 and August 2012(LARG group);and 200 patients underwent ORG between March 2000 and September2008(ORG group).The short-term therapeutic benefits between the two groups were analyzed.RESULTS:The LARG procedure offered significantly better benefits to the patients compared to the ORG procedure,including less intraoperative blood loss(103.1±19.5 mL vs 163.0±32.9 mL,P【0.0001),shorter postoperative hospital stay(6.8±1.2 d vs 9.5±1.6 d,P【0.0001),less frequent occurrence of postoperative complications(6.5%vs 13.5%,P=0.02),shorter time to mobilization(1.0±0.3 vs 3.3±0.4 d,P【0.0001),shorter time to bowel opening(3.3±0.7 d vs 4.5±0.7 d,P【0.0001),and shorter time to normal diet(3.0±0.4 vs d 3.8±0.5 d,P【0.0001).However,LARG required a longer time to complete than the ORG procedure(192.3±20.9 min vs 180.0±26.9 min,P【0.0001).CONCLUSION:Compared to ORG,LARG is safer,more effective,and less invasive for treating gastric cancer,with better short-term efficacy.

文摘BACKGROUND Gastric cancer is one of the most common cancers worldwide, with a 5-year survival rate of only 20%. The age of onset of gastric cancer is in line with the general rule of cancer. Most of them occur after middle age, mostly between 40and 60 years old, with an average age of about 50 years old, and only 5% of patients are under 30 years old. The incidence of male is higher than that of female.AIM To investigate the short-term efficacy and influencing factors of chemotherapy combined with irinotecan in patients with advanced gastric cancer.METHODS Eighty patients with advanced gastric cancer who were treated in our hospital from January 2019 to January 2022 were selected. The patients were divided into an observation group(n = 40) and control group(n = 40) by the envelope method.The control group was given preoperative routine chemotherapy. The observation group was treated with irinotecan in addition to the chemotherapy given to the control group. The short-term efficacy of treatment in the two groups, as well as tumor marker levels and quality of life before and after treatment were evaluated.RESULTS The short-term treatment effect in the observation group was better than that in the control group(P < 0.05), and the total effective rate was 57.50%. The age and proportion of tumor node metastasis(TNM) stage IV patients with ineffective chemotherapy in the observation group were(65.12 ± 5.71) years and 52.94%,respectively, which were notably higher than those of patients with effective chemotherapy(P < 0.05), while the Karnofsky Performance Scale score was(67.70± 3.83) points, which was apparently lower than that of patients with effective chemotherapy(P <0.05). After 3 mo of treatment, the SF-36 scale scores of physiological function, energy, emotional function, and mental health in the observation group were 65.12 ± 8.14, 54.76 ± 6.70, 47.58 ± 7.22,and 66.16 ± 8.11 points, respectively, which were considerably higher than those in the control group(P < 0.05). The incidence rates of grade Ⅲ-Ⅳ diarrhea and grade Ⅲ-Ⅳ thrombocytopenia in the observation group were 32.50% and 25.00%, respectively, which were markedly higher than those in the control group(P < 0.05).CONCLUSION Chemotherapy combined with irinotecan in patients with advanced gastric cancer has a good short-term efficacy and can significantly reduce serum tumor markers and improve the quality of life of patients. The efficacy may be affected by the age and TNM stage of the patients, and its long-term efficacy needs further study.

文摘BACKGROUND Totally laparoscopic gastrectomy(TLG)entails both gastrectomy and gastrointestinal reconstruction under laparoscopy.Compared with laparoscopic assisted gastrectomy(LAG),TLG has been demonstrated in many studies to require a smaller surgical incision,result in a faster postoperative recovery and less pain and have comparable long-term efficacy,which has been a research hotspot in recent years.Whether TLG is equally safe and feasible for elderly patients remains unclear.AIM To compare the short-term efficacy of and quality of life(QOL)associated with TLG and LAG in elderly gastric cancer(GC)patients.METHODS The clinicopathological data of 462 elderly patients aged≥70 years who underwent LAG or TLG(including distal gastrectomy and total gastrectomy)between January 2017 and January 2022 at the Department of General Surgery,First Medical Center,Chinese PLA General Hospital were retrospectively collected.A total of 232 patients were in the LAG group,and 230 patients were in the TLG group.Basic patient information,clinicopathological characteristics,operation information and QOL data were collected to compare efficacy.Compared with those in the LAG group,intraoperative blood loss in the TLG group was significantly lower(P<0.001),and the time to first flatus and postoperative hospitalization time were significantly shorter(both P<0.001).The overall incidence of postoperative complications in the TLG group was significantly lower than that in the LAG group(P=0.01).Binary logistic regression results indicated that LAG and an operation time>220 min were independent risk factors for postoperative complications in elderly patients with GC(P<0.05).In terms of QOL,no statistically significant differences in various preoperative indicators were found between the LAG group and the LTG group(P>0.05).Compared with the laparoscopic-assisted total gastrectomy group,patients who received totally laparoscopic total gastrectomy had lower nausea and vomiting scores and higher satisfaction with their body image(P<0.05).Patients who underwent laparoscopic-assisted distal gastrectomy were more satisfied with their body image than patients in the totally laparoscopic distal gastrectomy group(P<0.05).CONCLUSION TLG is safe and feasible for elderly patients with GC and has outstanding advantages such as reducing intracorporeal blood loss,promoting postoperative recovery and improving QOL.
文摘Objective The benefit of short-term dual antiplatelet therapy(DAPT) following second-generation drug-eluting stents implantation has not been systematically evaluated. To bridge the knowledge gap,we did a meta-analysis to assess the efficacy of ≤6 months versus ≥12 months DAPT among patients with second-generation drug-eluting stents. Methods We searched online databases and identified randomized controlled trials that assess the clinical impact of short-term DAPT(≤6 months) published before March 3,2016. The efficacy endpoints included the incidence of all-cause death,myocardial infarction,cerebrovascular accidents,and definite or probable stent thrombosis. Safety endpoint defined as major bleeding was also evaluated and discussed. Results We included 5 trials that randomized 9473 participants(49.8%,short-term DAPT duration vs. 50.2%,standard duration). A total of 9445(99.7%) patients reported the efficacy endpoints,and the safety endpoint was available from 4 studies(n=8457). There was no significant difference in efficacy endpoints between short-term and standard DAPT duration(≥12 months) [risk ratio(RR) 0.96; 95% confidence intervals(CI),0.80-1.15]. Short-term DAPT duration did not significantly increase the individual risk of all-cause death,myocardial infarction,cerebrovascular accidents,or definite or probable stent thrombosis. Although short-term DAPT obviously reduced risk of major bleeding compared with standard DAPT(RR 0.53; 95% CI,0.29-0.96),significant publication bias was found when accessing the safety endpoint of the 4 studies(Egger's test,P=0.009). Conclusions The efficacy of short-term DAPT was comparable with that of standard duration DAPT.DAPT less than 6 months may be appropriate for patients receiving second-generation drug-eluting stents implantation.
文摘BACKGROUND The efficacy and safety of transarterial chemoembolization(TACE)combined with lenvatinib plus programmed cell death protein-1(PD-1)for unresectable hepato-cellular carcinoma(HCC)have rarely been evaluated and it is unknown which factors are related to efficacy.AIM To evaluate the efficacy and independent predictive factors of TACE combined with lenvatinib plus PD-1 inhibitors for unresectable HCC.METHODS This study retrospectively enrolled patients with unresectable HCC who received TACE/lenvatinib/PD-1 treatment between March 2019 and April 2022.Overall survival(OS)and progression-free survival(PFS)were determined.The objective response rate(ORR)and disease control rate(DCR)were evaluated in accordance with the modified Response Evaluation Criteria in Solid Tumors.Additionally,the prognostic factors affecting the clinical outcome were assessed.RESULTS One hundred and two patients were enrolled with a median follow-up duration of 12.63 months.The median OS was 26.43 months(95%CI:17.00-35.87),and the median PFS was 10.07 months(95%CI:8.50-11.65).The ORR and DCR were 61.76%and 81.37%,respectively.The patients with Barcelona Clinic Liver Cancer Classification(BCLC)B stage,early neutrophil-to-lymphocyte ratio(NLR)response(decrease),or early alpha-fetoprotein(AFP)response(decrease>20%)had superior OS and PFS than their counterparts.CONCLUSION This study showed that TACE/lenvatinib/PD-1 treatment was well tolerated with encouraging efficacy in patients with unresectable HCC.The patients with BCLC B-stage disease with early NLR response(decrease)and early AFP response(decrease>20%)may achieve better clinical outcomes with this triple therapy.

文摘BACKGROUND Previous studies have reported that low hematocrit levels indicate poor survival in patients with ovarian cancer and cervical cancer,the prognostic value of hematocrit for colorectal cancer(CRC)patients has not been determined.The prognostic value of red blood cell distribution width(RDW)for CRC patients was controversial.AIM To investigate the impact of RDW and hematocrit on the short-term outcomes and long-term prognosis of CRC patients who underwent radical surgery.METHODS Patients who were diagnosed with CRC and underwent radical CRC resection between January 2011 and January 2020 at a single clinical center were included.The short-term outcomes,overall survival(OS)and disease-free survival(DFS)were compared among the different groups.Cox analysis was also conducted to identify independent risk factors for OS and DFS.RESULTS There were 4258 CRC patients who underwent radical surgery included in our study.A total of 1573 patients were in the lower RDW group and 2685 patients were in the higher RDW group.There were 2166 and 2092 patients in the higher hematocrit group and lower hematocrit group,respectively.Patients in the higher RDW group had more intraoperative blood loss(P<0.01)and more overall complications(P<0.01)than did those in the lower RDW group.Similarly,patients in the lower hematocrit group had more intraoperative blood loss(P=0.012),longer hospital stay(P=0.016)and overall complications(P<0.01)than did those in the higher hematocrit group.The higher RDW group had a worse OS and DFS than did the lower RDW group for tumor node metastasis(TNM)stage I(OS,P<0.05;DFS,P=0.001)and stage II(OS,P=0.004;DFS,P=0.01)than the lower RDW group;the lower hematocrit group had worse OS and DFS for TNM stage II(OS,P<0.05;DFS,P=0.001)and stage III(OS,P=0.001;DFS,P=0.001)than did the higher hematocrit group.Preoperative hematocrit was an independent risk factor for OS[P=0.017,hazard ratio(HR)=1.256,95%confidence interval(CI):1.041-1.515]and DFS(P=0.035,HR=1.194,95%CI:1.013-1.408).CONCLUSION A higher preoperative RDW and lower hematocrit were associated with more postoperative complications.However,only hematocrit was an independent risk factor for OS and DFS in CRC patients who underwent radical surgery,while RDW was not.
文摘Background The extended thymectomy for myasthenia gravis (MG) is currently available, but in 20%-40% of the patients the results were not satisfactory. There are no ideal indicators forecasting surgical results before operation. The surface enhanced laser desorption ionization-time of flight-mass spectroscopy (SELDI-TOF-MS) is a currently new technique for detection of protein profiles, and some progresses have been made in cancer diagnosis and efficacy evaluation, but there is no report on efficacy forecasting of MG surgery. This study aimed to establish an efficacy prognosis model for forecasting the efficacy of surgery for MG by analysis of serum protein profiles of MG patients before surgery. Methods Fifty-six MG patients 6 months after extended thymectomy were enrolled in the study. They were classified into effective or non-effective groups according to symptoms and medication. Their pre-operative blood samples were analyzed for protein profiles by the SELDI-TOF MS technique, and protein peaks were identified for establishment of the efficacy prognosis model of MG surgery. Additional 100 MG patients were subjected to model validation and their pre-operation protein profiles reviewed for post-operative results. The results were compared with those of the post-operative follow-up so as to validate the prognosis model. Results For the model establishment, symptoms were improved in 33 patients and not improved in 18 patients, with an effective rate of 64.7%. Five (8.9%) patients were lost to follow-up. Within the molecular weight range of 1 000 to 20 000, 3 specific protein peaks were found to be significantly different between the effective and non-effective groups, ie M4110-76, M3394-58, and M1258-55. Using the efficacy prognosis model constructed with these data, the accuracy rate of classification was 87.9% for the effective group, and 83.3% for the non-effective group, with a total accuracy rate of 86.3%. For the model evaluation, 2 (8.9%) patients were lost to follow-up, 62 patients were effective and 36 were non- effective. By comparing with the real results of follow-up with 65 effective and 33 non-effective patients with an effective rate of 66.3%, the accuracy rate of prediction by the prognosis model was 86.2% for the effective group, and was 81.8% for the non-effective group with a total accuracy rate of 84.5%. Conclusions By protein profiles analysis of pre-operative blood samples taken from MG patients with the SELDI-TOF MS technique, protein peaks correlated with surgery efficacy in MG patients can be found for primary forecasting short-term efficacy of surgery for MG patients.

文摘Short-term(up to 30 days)predictions of Earth Rotation Parameters(ERPs)such as Polar Motion(PM:PMX and PMY)play an essential role in real-time applications related to high-precision reference frame conversion.Currently,least squares(LS)+auto-regressive(AR)hybrid method is one of the main techniques of PM prediction.Besides,the weighted LS+AR hybrid method performs well for PM short-term prediction.However,the corresponding covariance information of LS fitting residuals deserves further exploration in the AR model.In this study,we have derived a modified stochastic model for the LS+AR hybrid method,namely the weighted LS+weighted AR hybrid method.By using the PM data products of IERS EOP 14 C04,the numerical results indicate that for PM short-term forecasting,the proposed weighted LS+weighted AR hybrid method shows an advantage over both the LS+AR hybrid method and the weighted LS+AR hybrid method.Compared to the mean absolute errors(MAEs)of PMX/PMY sho rt-term prediction of the LS+AR hybrid method and the weighted LS+AR hybrid method,the weighted LS+weighted AR hybrid method shows average improvements of 6.61%/12.08%and 0.24%/11.65%,respectively.Besides,for the slopes of the linear regression lines fitted to the errors of each method,the growth of the prediction error of the proposed method is slower than that of the other two methods.
文摘BACKGROUND Ovarian cancer is one of the most common malignant tumors in female reproductive system in the world,and the choice of its treatment is very important for the survival rate and prognosis of patients.Traditional open surgery is the main treatment for ovarian cancer,but it has the disadvantages of big trauma and slow recovery.With the continuous development of minimally invasive technology,minimally invasive laparoscopic surgery under general anesthesia has been gradually applied to the treatment of ovarian cancer because of its advantages of less trauma and quick recovery.However,the efficacy and safety of minimally invasive laparoscopic surgery under general anesthesia in the treatment of ovarian cancer are still controversial.AIM To explore the efficacy and safety of general anesthesia minimally invasive surgery in the treatment of ovarian cancer.METHODS The clinical data of 90 patients with early ovarian cancer in our hospital were analyzed retrospectively.According to the different surgical treatment methods,patients were divided into study group and control group(45 cases in each group).The study group received minimally invasive laparoscopic surgery under general anesthesia for ovarian cancer,while the control group received traditional open surgery for ovarian cancer.The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire(EORTC QLQ-C30),clinical efficacy and safety of the two groups were compared.RESULTS The intraoperative blood loss,length of hospital stay,postoperative gas evacuation time,and postoperative EORTC QLQ-C30 score of the study group were significantly better than those of the control group(P<0.05).The incidence of postoperative complications in the study group was significantly lower than in the control group(P<0.05).The two groups had no significant differences in the preoperative adrenocorticotropic hormone(ACTH),androstenedione(AD),cortisol(Cor),cluster of differentiation 3 positive(CD3+),and cluster of differentiation 4 positive(CD4+)indexes(P>0.05).In contrast,postoperatively,the study group's ACTH,AD,and Cor indexes were lower,and the CD3+and CD4+indexes were higher than those in the control group(P<0.05).CONCLUSION Minimally invasive laparoscopic surgery under general anesthesia in patients with early ovarian cancer can significantly improve the efficacy and safety,improve the short-term prognosis and quality of life of patients,and is worth popularizing.

文摘Objective: Cetuximab is an effective medicine for colorectal cancer bearing wild type Kras. However, few studies of cetuximab on patients with noncolorectal gastrointestinal cancer were available now. The aim of this study was to summarize the efficacy and safety profiles base-on the experiences of 16 patients with noncolorectal gastrointestinal cancer accepted cetuximab-contained regimens treatment. Methods: The clinical data of all patients with noncolorectal gastrointestinal cancer treated by cetuximab combined with chemotherapy and/or radiotherapy from October 1st 2006 to Jun 30th 2009 in Sun Yat-sen University Cancer Center were collected. Results: (1) A total of 16 patients enrolled, including gastric cancer, esophageal carcinoma, pancreatic cancer and cholangiocarcinoma (8, 6, 1 and 1, respectively). The cetuximab was administered 92 cycles totally with median cycle of 4. (2) PR, SD and PD obtained in 4, 3 and 2 patients respectively in cetuximab + chemotherapy group. The disease control rate, median l-rP and median OS were 77.8% (7/9), 3.5 months and 3.5 months, respectively. (3) Both of patients in cetuximab + radiotherapy group achieved PR with median TTP of 4 months and 7 months, with median OS of 14 and 28 months, respectively. (4) in evaluable patients, 3 PR obtained in first-line setting, 1 PD and 1 SD achieved in second-line setting, 2 SD and 1 PD appeared in third-line and more than third-line setting. (5) The commonly side effect was neutropenia, however, rash and hypomagnesemia were the common side effects related to cetuximab. Conclusion: Cetuximab-contained regimens show a promising disease control rate, especially in first-line setting, in patients with noncolorectal gastrointestinal cancer, and the side effects both related to cytotoxic agents and related to cetuximab itself is tolerable and manageable. Of course, more phase Ⅲ clinical trails are needed urgently.
文摘Objective:To provide real-world evidence for the application of first-line dacomitinib treatment for epidermal growth factor receptor(EGFR)21L858R mutant non-small cell lung cancer(NSCLC)patients in China and to explore the factors influencing the efficacy and safety.Methods:A longitudinal,consecutive case-series,multicenter study with mixed prospective and retrospective data was conducted.The primary endpoint was progression-free survival(PFS),and the secondary endpoints included duration of treatment(DOT),overall survival(OS),objective response rate(ORR),disease control rate(DCR)and safety.Results:A total of 155 EGFR 21L858R mutant patients treated with first-line dacomitinib were included.The median follow-up time for these patients was 20.4 months.Among 134 patients with evaluable lesions,the ORR was 70.9%and the DCR was 96.3%.The median PFS was 16.3[95%confidence interval(95%CI),13.7−18.9]months.Multivariate Cox regression analysis suggested that the baseline brain metastasis(BM)status[with vs.without BM:hazard ratio(HR),1.331;95%CI,0.720−2.458;P=0.361]and initial doses(45 mg vs.30 mg:HR,0.837;95%CI,0.427−1.641;P=0.604)did not significantly affect the median PFS.The median DOT was 21.0(95%CI,17.5−24.6)months and the median OS was not reached.Genetic tests were performed in 64 patients after progression,among whom 29(45.3%)patients developed the EGFR 20T790M mutation.In addition,among the 46 patients who discontinued dacomitinib treatment after progression,31(67.4%)patients received subsequent third-generation EGFR-tyrosine kinase inhibitors.The most common grade 3−4 adverse events were rash(10.4%),diarrhea(9.1%),stomatitis(7.1%)and paronychia(4.5%).The incidence of grade 3−4 rash was significantly higher in the 45 mg group than that in the 30 mg group(21.9%vs.7.5%,P=0.042).Conclusions:First-line dacomitinib treatment demonstrated promising efficacy and tolerable adverse events among EGFR 21L858R mutant NSCLC patients in China.

文摘BACKGROUND Severe acute pancreatitis(SAP),a condition with rapid onset,critical condition and unsatisfactory prognosis,poses a certain threat to human health,warranting optimization of relevant treatment plans to improve treatment efficacy.AIM To evaluate the efficacy and safety of computerized tomography-guided the-rapeutic percutaneous puncture catheter drainage(CT-TPPCD)combined with somatostatin(SS)in the treatment of SAP.METHODS Forty-two SAP patients admitted to The Second Affiliated Hospital of Fujian Medical University from June 2020 to June 2023 were selected.On the basis of routine treatment,20 patients received SS therapy(control group)and 22 patients were given CT-TPPCD plus SS intervention(research group).The efficacy,safety(pancreatic fistula,intra-abdominal hemorrhage,sepsis,and organ dysfunction syndrome),abdominal bloating and pain relief time,bowel recovery time,hospital stay,inflammatory indicators(C-reactive protein,interleukin-6,and pro-calcitonin),and Acute Physiology and Chronic Health Evaluation(APACHE)II score of both groups were evaluated for comparison.RESULTS Compared with the control group,the research group had a markedly higher total effective rate,faster abdominal bloating and pain relief and bowel recovery,INTRODUCTION Pancreatitis,an inflammatory disease occurring in the pancreatic tissue,is classified as either acute or chronic and is associated with high morbidity and mortality,imposing a socioeconomic burden[1,2].The pathogenesis of this disease involves early protease activation,activation of nuclear factor kappa-B-related inflammatory reactions,and infiltration of immune cells[3].Severe acute pancreatitis(SAP)is a serious condition involving systemic injury and subsequent possible organ failure,accounting for 20%of all acute pancreatitis cases[4].SAP is also characterized by rapid onset,critical illness and unsatisfactory prognosis and is correlated with serious adverse events such as systemic inflammatory response syn-drome and acute lung injury,threatening the health of patients[5,6].Therefore,timely and effective therapeutic inter-ventions are of great significance for improving patient prognosis and ensuring therapeutic effects.Somatostatin(SS),a peptide hormone that can be secreted by endocrine cells and the central nervous system,is in-volved in the regulatory mechanism of glucagon and insulin synthesis in the pancreas[7].It has complex and pleiotropic effects on the gastrointestinal tract,which can inhibit the release of gastrointestinal hormones and negatively modulate the exocrine function of the stomach,pancreas and bile,while exerting a certain influence on the absorption of the di-gestive system[8,9].SS has shown certain clinical effectiveness when applied to SAP patients and can regulate the severity of SAP and immune inflammatory responses,and this regulation is related to its influence on leukocyte apoptosis and adhesion[10,11].Computerized tomography-guided therapeutic percutaneous puncture catheter drainage(CT-TPPCD)is a surgical procedure to collect lesion fluid and pus samples from necrotic lesions and perform puncture and drainage by means of CT image examination and precise positioning[12].In the research of Liu et al[13],CT-TPPCD applied to pa-tients undergoing pancreatic surgery contributes to not only good curative effects but also a low surgical risk.Baudin et al[14]also reported that CT-TPPCD has a clinical success rate of 64.6%in patients with acute infectious necrotizing pan-creatitis,with nonfatal surgery-related complications found in only two cases,suggesting that this procedure is clinically effective and safe in the treatment of the disease.In light of the limited studies on the efficacy and safety of SS plus CT-TPPCD in SAP treatment,this study performed a relevant analysis to improve clinical outcomes in SAP patients.
