In this study, we aimed to explorethe influence of KIF15 expression on the efficacy of neoadjuvant chemotherapy (NAC) and evaluate itsclinical value in predicting prognosis for BC patients.Methods Immunohistochemistry was used to detect KIF15 expression in 93 BC patients undergoingNAC to analyze the relationship between KIF15 expression and clinical efficacy and analytical parameters.Results Of the 93 BC patients enrolled, 24.73% who underwent NAC had higher KIF15 expression levels,showing positive correlations with ER, HER-2, Ki67, and lymph node metastasis (P < 0.05). The clinicalbenefit of NAC was 70.97%, and the major histological response (MHR) rate was 61.29%. The effectivetherapeutic rate in patients with high KIF15 expression was 95.65%, while the MHR rate was 65.22%.Various molecular BC subtypes with varied clinical and pathological responses exhibited correlation toa large extent. Of all the BC patients studied, 84% of the triple-negative breast cancer (TNBC) patientswere evaluated as clinically effective, and 52% of the TNBC patients were evaluated as pathologicallyeffective, and these values were significantly higher than those of the other molecular types (P < 0.05).The expression of KIF15 in 25 TNBC patients showed positive correlations with lymph node metastasis.Conclusion Overexpression of KIF15 was shown to increase BC sensitivity to chemotherapy anddemonstrated better outcomes.展开更多

The incidence is slightly higher in males. Onset can occur at any age;however, primary high grade osteosarcoma usually occurs in the second decade of life. Historically patients with osteosarcoma were treated with immediate wide or radical amputation. Despite the treatment, 80% patients with apparently isolated disease died of distant metastases. In recent years the number of patients with osteosarcoma of the limb treated by amputation + chemotherapy has increased. In our study, we divided the patients into two groups. One group (A) was treated with amputation + adjuvant chemotherapy. The other group (B) was treated with neo-adjuvant chemotherapy + amputation followed by adjuvant-chemotherapy. In our study, the margin negativity in post surgical specimen was significantly higher (P-value 0.0007) for the group treated with neo-adjuvant chemotherapy. Local recurrence in the group treated without neoadjuvant chemotherapy was significantly more (P-value 0.0005).The systemic recurrence at the end of 6 months was higher the group treated without neoadjuvant chemotherapy (P-value 0.0169).However systemic recurrence between 6 months -1 year and 1 year - 2 years were not significant(P-values 0.1501 and 0.4902). From the above figures it may be concluded that treatment with neo-adjuvant chemotherapy + amputation + adjuvant chemotherapy had definite advantages over upfront amputation + adjuvant chemotherapy.)展开更多

Modalities that have been used to monitor response to neo-adjuvant chemotherapy (NAC) include physical examination (PE), ultrasound (US), and magnetic resonance imaging (MRI). The purpose of this study was to evaluate the accuracy of PE, US, and MRI in predicting the response to NAC in patients with breast cancer. Methods According to the response evaluation criteria in solid tumors guidelines, the largest unidimensional measurement of the tumor diameter evaluated by PE, US, and MRI before and after NAC was classified into four grades, including clinical complete response, clinical partial response, clinical progressive disease, clinical stable disease, and compared with the final histopathological examination. Results Of the 64 patients who received NAC, the pathologic complete response (pCR) was shown in 13 of 64 patients (20%). The sensitivity of PE, US, and MRI in predicting the major pathologic response was 73%, 75%, and 80%, respectively, and the specificity was 45%, 50%, and 50% respectively. For predicting a pCR, the sensitivity of PE, US, and MRI was 46%, 46%, and 39%, respectively, and the specificity was 65%, 98%, and 92% respectively. Conclusions Compared with final pathologic findings, all these three clinical and imaging modalities tended to obviously underestimate the pCR rate. A more appropriate, universal, and practical standard by clinical and imaging modalities in predicting the response to neo-adjuvant chemotherapy in vivo is essential.展开更多

Methods: A total of 60 tumor patients receiving oxaliplatin for 1 - 6 cycles of chemotherapy from January to September 2023 were selected. 30 patients were selected from January to March and divided into the control group, and 30 patients were selected from July to 9 as the experimental group. The control group received conventional chemotherapy nursing, while the experimental group received integrated nursing. Anxiety, peripheral nerve toxicity stage and quality of life score were compared between the two groups before and after intervention. Results: After intervention, the scores of the self-rating Anxiety Scale (SAS) and the total scores of the oxaliplatin Levi specific sensory neurotoxicity scale in the experimental group were significantly lower than those in the control group, and the differences were statistically significant (P< 0.05);The Quality of Life Scale (FACT-G) score of cancer patients was higher than that of control group, and the difference was statistically significant (P< 0.05). Conclusion: The integrated nursing model can effectively reduce the anxiety of patients, reduce the incidence of peripheral nerve injury and improve the quality of life of patients.展开更多

文摘Neo-adjuvant chemotherapy(NACT)is utilized in locally advanced oral cancers to reduce the tumor burden and downstage the tumor to be amenable for definitive surgical management.Its long-term results compared to upfront surgical resection was not encouraging.Immunotherapy has now been used not only in recurrence and metastatic setting but also in the locally advanced tumor management regimens.The purpose of this concept paper is to bring forward the rationale to use a fixed low-dose immunotherapy agent as a potentiator to the standard NACT regimen and recommend their future investigation in oral cancer management.
文摘Objective:Surgical resection of pancreatic cancer remains the only potentially curative treatment for pancreatic ductal adenocarcinoma.The robotic platform has been introduced to surgical practice and recent large studies from national registries have demonstrated similar or improved peri-operative outcomes compared to the standard open approach.Neo-adjuvant chemotherapy is increasingly being offered to patients with borderline resectable/locally advanced disease but this has led to more challenging resections.Numbers of patients undergoing minimally invasive resection following neo-adjuvant chemotherapy remain low.The aim of this review is to assess the current evidence for the peri-operative safety and long-term oncological outcomes associated with minimally invasive pancreatic resection following neo-adjuvant chemotherapy.Methods:Medline,Embase and Cochrane Central Register for Clinical Trials were searched up until 31st October 2021.The search terms include“minimally invasive”,“robotic”,“laparoscopic”,“pancreatectomy”,“pancreatic resection”,“whipple's pancreaticoduodenectomy”,“distal pancreatectomy”,“chemotherapy”,“neo-adjuvant chemotherapy”,“radiotherapy”,“neo-adjuvant chemoradiotherapy”,“induction therapy”,and“conversion surgery”.All studies including patients undergoing pancreatic resections were included.Studies which did not clearly state the approach to resection(minimally invasive or open)were excluded.Results:Seventy-eight studies were identified of which 8 compared open and minimally invasive resection following neo-adjuvant chemotherapy.There was insufficient data to perform a meta-analysis.Robotic surgery was associated with lower blood loss and shorter length of hospital stay.Three-year overall survival rates were similar between patients who underwent robotic or open resection however the robotic approach was associated with higher lymph node yield and a lower R1 resection rate.Conclusion:Currently the evidence for minimally invasive surgery following neo-adjuvant chemotherapy is limited.Long-term oncological outcomes are similar to patients undergoing open resection and there is some evidence to suggest superior peri-operative outcomes.As numbers are limited,future studies analysing national and international databases on minimally invasive pancreatic resection are required to provide sufficient evidence to support the use of minimally invasive pancreatic resection following neo-adjuvant chemotherapy in high-risk groups.

文摘Objective The relationship between the expression of kinesin family member 15 (KIF15) andclinicopathological features in breast cancer (BC) remains controversial. In this study, we aimed to explorethe influence of KIF15 expression on the efficacy of neoadjuvant chemotherapy (NAC) and evaluate itsclinical value in predicting prognosis for BC patients.Methods Immunohistochemistry was used to detect KIF15 expression in 93 BC patients undergoingNAC to analyze the relationship between KIF15 expression and clinical efficacy and analytical parameters.Results Of the 93 BC patients enrolled, 24.73% who underwent NAC had higher KIF15 expression levels,showing positive correlations with ER, HER-2, Ki67, and lymph node metastasis (P < 0.05). The clinicalbenefit of NAC was 70.97%, and the major histological response (MHR) rate was 61.29%. The effectivetherapeutic rate in patients with high KIF15 expression was 95.65%, while the MHR rate was 65.22%.Various molecular BC subtypes with varied clinical and pathological responses exhibited correlation toa large extent. Of all the BC patients studied, 84% of the triple-negative breast cancer (TNBC) patientswere evaluated as clinically effective, and 52% of the TNBC patients were evaluated as pathologicallyeffective, and these values were significantly higher than those of the other molecular types (P < 0.05).The expression of KIF15 in 25 TNBC patients showed positive correlations with lymph node metastasis.Conclusion Overexpression of KIF15 was shown to increase BC sensitivity to chemotherapy anddemonstrated better outcomes.
文摘Osteosarcoma is a tumour characterized by the production of osteoid by malignant cells. The incidence is approximately 1 to 3 million/year. The incidence is slightly higher in males. Onset can occur at any age;however, primary high grade osteosarcoma usually occurs in the second decade of life. Historically patients with osteosarcoma were treated with immediate wide or radical amputation. Despite the treatment, 80% patients with apparently isolated disease died of distant metastases. In recent years the number of patients with osteosarcoma of the limb treated by amputation + chemotherapy has increased. In our study, we divided the patients into two groups. One group (A) was treated with amputation + adjuvant chemotherapy. The other group (B) was treated with neo-adjuvant chemotherapy + amputation followed by adjuvant-chemotherapy. In our study, the margin negativity in post surgical specimen was significantly higher (P-value 0.0007) for the group treated with neo-adjuvant chemotherapy. Local recurrence in the group treated without neoadjuvant chemotherapy was significantly more (P-value 0.0005).The systemic recurrence at the end of 6 months was higher the group treated without neoadjuvant chemotherapy (P-value 0.0169).However systemic recurrence between 6 months -1 year and 1 year - 2 years were not significant(P-values 0.1501 and 0.4902). From the above figures it may be concluded that treatment with neo-adjuvant chemotherapy + amputation + adjuvant chemotherapy had definite advantages over upfront amputation + adjuvant chemotherapy.)
文摘BACKGROUND Malnourishment and sarcopenia are well documented phenomena in oesophageal cancer.Patients undergoing neo-adjuvant chemotherapy prior to oesophagectomy have complex nutritional needs.AIM To examine the effect of regular nutritional support via feeding jejunostomy on overall body composition in patients undergoing neo-adjuvant chemotherapy prior to oesophagectomy for oesophageal cancer.METHODS Retrospective data were collected for 15 patients before and after neo-adjuvant chemotherapy.All patients had feeding jejunostomies inserted at staging laparoscopy prior to neo-adjuvant chemotherapy and underwent regular jejunostomy feeding.Changes in body composition were determined by analysis of computed tomography imaging.RESULTS Patient age was 61.3±12.8 years,and 73%of patients were male.The time between start of chemotherapy and surgery was 107±21.6 d.There was no change in weight(74.5±14.1 kg to 74.8±13.1 kg)and body mass index(26.0±3.8 kg/m^2 to 26.1±3.4 kg/m^2).Body composition analysis revealed a statistically significant decrease in lumbar skeletal muscle index despite regular feeding(45.8±8.0 cm^2/m^2 to 43.5±7.3 cm^2/m^2;P=0.045).The proportion of sarcopenic patients increased(33.3% to 60%).Six patients(40%)experienced dose-limiting toxicity during chemotherapy.CONCLUSION Regular jejunostomy feeding during neo-adjuvant chemotherapy can maintain weight and adipose tissue.Feeding alone is not sufficient to maintain muscle mass.Further insight into the underlying processes causing reduced muscle mass in cancer patients may help to provide targeted interventions.
文摘Background Accurate evaluation of response following chemotherapy treatment is essential for surgical decision making in patients with breast cancer. Modalities that have been used to monitor response to neo-adjuvant chemotherapy (NAC) include physical examination (PE), ultrasound (US), and magnetic resonance imaging (MRI). The purpose of this study was to evaluate the accuracy of PE, US, and MRI in predicting the response to NAC in patients with breast cancer. Methods According to the response evaluation criteria in solid tumors guidelines, the largest unidimensional measurement of the tumor diameter evaluated by PE, US, and MRI before and after NAC was classified into four grades, including clinical complete response, clinical partial response, clinical progressive disease, clinical stable disease, and compared with the final histopathological examination. Results Of the 64 patients who received NAC, the pathologic complete response (pCR) was shown in 13 of 64 patients (20%). The sensitivity of PE, US, and MRI in predicting the major pathologic response was 73%, 75%, and 80%, respectively, and the specificity was 45%, 50%, and 50% respectively. For predicting a pCR, the sensitivity of PE, US, and MRI was 46%, 46%, and 39%, respectively, and the specificity was 65%, 98%, and 92% respectively. Conclusions Compared with final pathologic findings, all these three clinical and imaging modalities tended to obviously underestimate the pCR rate. A more appropriate, universal, and practical standard by clinical and imaging modalities in predicting the response to neo-adjuvant chemotherapy in vivo is essential.
文摘Objective: To study the effect of Aidi Injection (艾迪注射液,ADI) applied in the bronchial artery infused (BAI) neo-adjuvant chemotherapy for stage ⅢA non-small cell lung cancer (NSCLC) before surgical operation.Methods: The 60 patients with NSCLC stage ⅢA underwent two courses BAI chemotherapy before tumor incision were assigned to two groups,the treatment and the control groups,using a random number table,30 in each group.ADI (100 mL) was given to the patients in the treatment group by adding into 500 mL of 5% glucose injection for intravenous dripping once daily,starting from 3 days before each course of chemotherapy,and it lasted for 14 successive days,so a total of 28 days of administration was completed.The therapeutic effectiveness and the adverse reaction that occurred were observed,and the levels of T-lymphocyte subsets,natural killer cell activity,and interleukin-2 in peripheral blood were measured before and after the treatment.Results: The effective rate in the treatment group was higher than that in the control group (70.0% vs.56.7%,P〈0.05).Moreover,as compared with the control group,the adverse reaction that occurred in the treatment group was less and mild,especially in terms of bone marrow suppression and liver function damage (P〈0.05).Cellular immune function was suppressed in NSCLC patients,but after treatment,it ameliorated significantly in the treatment group,showing significant difference as compared with that in the control group (P〈0.05).Conclusion: ADI was an ideal auxiliary drug for the patients in stage ⅢA NSCLC received BAI neo-chemotherapy before surgical operation;it could enhance the effectiveness of chemotherapy,ameliorate the adverse reaction and elevate patients' cellular immune function;therefore,it is worthy for spreading in clinical practice.
文摘BACKGROUND Neoadjuvant therapy is an essential modality for reducing the clinical stage of esophageal cancer;however,the superiority of neoadjuvant chemotherapy(nCT)or neoadjuvant chemoradiotherapy(nCRT)is unclear.Therefore,a discussion of these two modalities is necessary.AIM To investigate the benefits and complications of neoadjuvant modalities.METHODS To address this concern,predefined criteria were established using the PICO protocol.Two independent authors performed comprehensive searches using predetermined keywords.Statistical analyses were performed to identify significant differences between groups.Potential publication bias was visualized using funnel plots.The quality of the data was evaluated using the Risk of Bias Tool 2(RoB2)and the GRADE approach.RESULTS Ten articles,including 1928 patients,were included for the analysis.Significant difference was detected in pathological complete response(pCR)[P<0.001;odds ratio(OR):0.27;95%CI:0.16-0.46],30-d mortality(P=0.015;OR:0.4;95%CI:0.22-0.71)favoring the nCRT,and renal failure(P=0.039;OR:1.04;95%CI:0.66-1.64)favoring the nCT.No significant differences were observed in terms of survival,local or distal recurrence,or other clinical or surgical complications.The result of RoB2 was moderate,and that of the GRADE approach was low or very low in almost all cases.CONCLUSION Although nCRT may have a higher pCR rate,it does not translate to greater long-term survival.Moreover,nCRT is associated with higher 30-d mortality,although the specific cause for postoperative complications could not be identified.In the case of nCT,toxic side effects are suspected,which can reduce the quality of life.Given the quality of available studies,further randomized trials are required.

文摘BACKGROUND Advanced pancreatic cancer is resistant to chemotherapeutic drugs,resulting in limited treatment efficacy and poor prognosis.Combined administration of the chemotherapeutic gemcitabine and erlotinib is considered a potential first-line treatment for advanced pancreatic cancer.However,their comparative benefits and potential risks remain unclear.AIM To assess the clinical efficacy and safety of erlotinib combined with other chemotherapy regimens for the treatment of advanced pancreatic cancer.METHODS Literature on the clinical efficacy and safety of erlotinib combined with chemotherapy for advanced pancreatic cancer was retrieved through an online search.The retrieved literature was subjected to a methodological qualitative assessment and was analyzed using the RevMan 5.3 software.Ten randomized controlled trials involving 2444 patients with advanced pancreatic cancer were included in the meta-analysis.RESULTS Compared with chemotherapeutic treatment,erlotinib combined with chemotherapy significantly prolonged the progression-free survival time of pancreatic cancer patients[hazard ratio(HR)=0.78,95%CI:0.66-0.92,P=0.003].Meanwhile,the overall survival(HR=0.99,95%CI:0.72-1.37,and P=0.95)and disease control rate(OR=0.93,95%CI:0.45-0.91,P=0.84)were not significantly favorable.In terms of safety,the erlotinib and chemotherapy combination was associated with a significantly higher risk of diarrhea(OR=3.59,95%CI:1.63-7.90,P<0.05)and rash(OR=3.63,95%CI:1.64-8.01,P<0.05)compared with single-agent chemotherapy.Moreover,the risk of vomiting(OR=1.27,95%CI:0.62-2.59,P=0.51),regurgitation/anorexia(OR=1.61,95%CI:0.25-10.31,P=0.62),and infection(OR=0.72,95%CI:0.28-1.87,P=0.50)were not significant in either group.CONCLUSION Compared with a single chemotherapeutic modality,erlotinib combined with gemcitabine can prolong progression-free survival in pancreatic cancer,but does not improve survival benefit or disease control rate,and can increase the risk of diarrhea and rash.
文摘Objective: To investigate the effect of the integrated nursing model in the prevention of chemotherapy-induced peripheral injury. Methods: A total of 60 tumor patients receiving oxaliplatin for 1 - 6 cycles of chemotherapy from January to September 2023 were selected. 30 patients were selected from January to March and divided into the control group, and 30 patients were selected from July to 9 as the experimental group. The control group received conventional chemotherapy nursing, while the experimental group received integrated nursing. Anxiety, peripheral nerve toxicity stage and quality of life score were compared between the two groups before and after intervention. Results: After intervention, the scores of the self-rating Anxiety Scale (SAS) and the total scores of the oxaliplatin Levi specific sensory neurotoxicity scale in the experimental group were significantly lower than those in the control group, and the differences were statistically significant (P< 0.05);The Quality of Life Scale (FACT-G) score of cancer patients was higher than that of control group, and the difference was statistically significant (P< 0.05). Conclusion: The integrated nursing model can effectively reduce the anxiety of patients, reduce the incidence of peripheral nerve injury and improve the quality of life of patients.

文摘Objective Anthracycline-containing regimens are irreplaceable in neoadjuvant chemotherapy(NAC)for breast cancer(BC)at present.However,30% of early breast cancer(EBC)patients are resistant to anthracycline-containing chemotherapy,leading to poor prognosis and higher mortality.Ki-67 is associated with the prognosis and response to therapy,and it changes after NAC.Methods A total of 105 BC patients who received anthracycline-containing NAC were enrolled.Then,the optimal model of Ki-67 was selected,and its predictive efficacy was analyzed.Immunohistochemistry(IHC)was used to determine the estrogen receptor(ER),progesterone receptor(PR),and human epidermal growth factor receptor 2(HER-2)status and Ki-67 level.Fluorescent in situ hybridization(FISH)was used to verify the HER-2 when the IHC score was 2+.Results The post-NAC Ki67 level after treatment with anthracycline drugs was lower than pre-NAC Ki-67(19.6%±23.3%vs.45.6%±23.1%,P<0.001).Furthermore,patients with the Ki-67 decrease had a border line higher pathological complete response(pCR)rate(17.2%vs.0.0%,P=0.068),and a higher overall response rate(ORR)(73.6%vs.27.8%,P<0.001),when compared to patients without the Ki-67 decrease.The ΔKi-67 and ΔKi-67%were valuable markers for the prediction of both the pCR rate and ORR.The area under the curve(AUC)for ΔKi-67 on pCR and ORR was 0.809(0.698-0.921)and 0.755(0.655-0.855),respectively,while the AUC for ΔKi-67% on pCR and ORR was 0.857(0.742-0.972)and 0.720(0.618-0.822),respectively.Multivariate logistic regression model 1 revealed thatΔKi-67 was an independent predictor for both pCR[odds ratio(OR)=61.030,95% confidence interval(CI)=4.709-790.965;P=0.002]and ORR(OR=10.001,95%CI:3.044-32.858;P<0.001).Multivariate logistic regression model 2 revealed thatΔKi-67%was also an independent predictor for both pCR(OR=408.922,95%CI=8.908-18771.224;P=0.002)and ORR(OR=5.419,95%CI=1.842-15.943;P=0.002).Conclusions The present study results suggest thatΔKi67 andΔKi67%are candidate predictors for anthracycline-containing NAC response,and that they may provide various information for further systematic therapy after surgery in clinical practice.

文摘BACKGROUND The TRIANGLE operation involves the removal of all tissues within the triangle bounded by the portal vein-superior mesenteric vein,celiac axis-common hepatic artery,and superior mesenteric artery to improve patient prognosis.Although previously promising in patients with locally advanced pancreatic ductal adenocarcinoma(PDAC),data are limited regarding the long-term oncological outcomes of the TRIANGLE operation among resectable PDAC patients undergoing pancreaticoduodenectomy(PD).AIM To evaluate the safety of the TRIANGLE operation during PD and the prognosis in patients with resectable PDAC.METHODS This retrospective cohort study included patients who underwent PD for pancreatic head cancer between January 2017 and April 2023,with or without the TRIANGLE operation.Patients were divided into the PD_(TRIANGLE)and PD_(non-TRIANGLE)groups.Surgical and survival outcomes were compared between the two groups.Adequate adjuvant chemotherapy was defined as adjuvant chemotherapy≥6 months.RESULTS The PD_(TRIANGLE)and PD_(non-TRIANGLE) groups included 52 and 55 patients,respectively.There were no significant differences in the baseline characteristics or perioperative indexes between the two groups.Furthermore,the recurrence rate was lower in the PD_(TRIANGLE) group than in the PD_(non-TRIANGLE) group(48.1%vs 81.8%,P<0.001),and the local recurrence rate of PDAC decreased from 37.8%to 16.0%.Multivariate Cox regression analysis revealed that PD_(TRIANGLE)(HR=0.424;95%CI:0.256-0.702;P=0.001),adequate adjuvant chemotherapy≥6 months(HR=0.370;95%CI:0.222-0.618;P<0.001)and margin status(HR=2.255;95%CI:1.252-4.064;P=0.007)were found to be independent factors for the recurrence rate.CONCLUSION The TRIANGLE operation is safe for PDAC patients undergoing PD.Moreover,it reduces the local recurrence rate of PDAC and may improve survival in patients who receive adequate adjuvant chemotherapy.

文摘BACKGROUND The efficacy of neoadjuvant chemotherapy(NAC)in advanced gastric cancer(GC)is still a controversial issue.AIM To find factors associated with chemosensitivity to NAC treatment and to provide the optimal therapeutic strategies for GC patients receiving NAC.METHODS The clinical information was collected from 230 GC patients who received NAC treatment at the Central South University Xiangya School of Medicine Affiliated Haikou Hospital from January 2016 to December 2020.Least absolute shrinkage and selection operator logistic regression analysis was used to find the possible predictors.A nomogram model was employed to predict the response to NAC.RESULTS In total 230 patients were finally included in this study,including 154 males(67.0%)and 76 females(33.0%).The mean age was(59.37±10.60)years,ranging from 24 years to 80 years.According to the tumor regression grade standard,there were 95 cases in the obvious response group(grade 0 or grade 1)and 135 cases in the poor response group(grade 2 or grade 3).The obvious response rate was 41.3%.Least absolute shrinkage and selection operator analysis showed that four risk factors significantly related to the efficacy of NAC were tumor location(P<0.001),histological differentiation(P=0.001),clinical T stage(P=0.008),and carbohydrate antigen 724(P=0.008).The C-index for the prediction nomogram was 0.806.The calibration curve revealed that the predicted value exhibited good agreement with the actual value.Decision curve analysis showed that the nomogram had a good value in clinical application.CONCLUSION A nomogram combining tumor location,histological differentiation,clinical T stage,and carbohydrate antigen 724 showed satisfactory predictive power to the response of NAC and can be used by gastrointestinal surgeons to determine the optimal treatment strategies for advanced GC patients.
文摘BACKGROUND The effectiveness of neoadjuvant therapy in esophageal cancer(EC)treatment is still a subject of debate.AIM To compare the clinical efficacy and toxic side effects between neoadjuvant chemoradiotherapy(nCRT)and neoadjuvant chemotherapy(nCT)for locally advanced EC(LAEC).METHODS A comprehensive search was conducted using multiple databases,including PubMed,EMBASE,MEDLINE,Science Direct,The Cochrane Library,China National Knowledge Infrastructure,Wanfang Database,Chinese Science and Technology Journal Database,and Chinese Biomedical Literature Database Article.Studies up to December 2022 comparing nCRT and nCT in patients with EC were selected.RESULTS The analysis revealed significant differences between nCRT and nCT in terms of disease-free survival.The results indicated that nCRT provided better outcomes in terms of the 3-year overall survival rate(OSR)[odds ratio(OR)=0.95],complete response rate(OR=3.15),and R0 clearance rate(CR)(OR=2.25).However,nCT demonstrated a better 5-year OSR(OR=1.02)than nCRT.Moreover,when compared to nCRT,nCT showed reduced risks of cardiac complications(OR=1.15)and pulmonary complications(OR=1.30).CONCLUSION Overall,both nCRT and nCT were effective in terms of survival outcomes for LAEC.However,nCT exhibited better performance in terms of postoperative complications.

文摘Dose-dense chemotherapy is the preferred first-line therapy for triple-negative breast cancer(TNBC),a highly aggressive disease with a poor prognosis.This treatment uses the same drug doses as conventional chemotherapy but with shorter dosing intervals,allowing for promising clinical outcomes with intensive treatment.However,the frequent systemic administration used for this treatment results in systemic toxicity and low patient compliance,limiting therapeutic efficacy and clinical benefit.Here,we report local dose-dense chemotherapy to treat TNBC by implanting 3D printed devices with timeprogrammed pulsatile release profiles.The implantable device can control the time between drug releases based on its internal microstructure design,which can be used to control dose density.The device is made of biodegradable materials for clinical convenience and designed for minimally invasive implantation via a trocar.Dose density variation of local chemotherapy using programmable release enhances anti-cancer effects in vitro and in vivo.Under the same dose density conditions,device-based chemotherapy shows a higher anticancer effect and less toxic response than intratumoral injection.We demonstrate local chemotherapy utilizing the implantable device that simulates the drug dose,number of releases,and treatment duration of the dose-dense AC(doxorubicin and cyclophosphamide)regimen preferred for TNBC treatment.Dose density modulation inhibits tumor growth,metastasis,and the expression of drug resistance-related proteins,including p-glycoprotein and breast cancer resistance protein.To the best of our knowledge,local dose-dense chemotherapy has not been reported,and our strategy can be expected to be utilized as a novel alternative to conventional therapies and improve anti-cancer efficiency.

文摘BACKGROUND Colorectal cancer is the third most prevalent malignancy globally and ranks second in cancer-related mortality,with the liver being the primary organ of metastasis.Preoperative chemotherapy is widely recommended for initially or potentially resectable colorectal liver metastases(CRLMs).Tumour pathological response serves as the most important and intuitive indicator for assessing the efficacy of chemotherapy.However,the postoperative pathological results reveal that a considerable number of patients exhibit a poor response to preoperative chemotherapy.Body mass index(BMI)is one of the factors affecting the tumori-genesis and progression of colorectal cancer as well as prognosis after various antitumour therapies.Several studies have indicated that overweight and obese patients with metastatic colorectal cancer experience worse prognoses than those with normal weight,particularly when receiving first-line chemotherapy regimens in combination with bevacizumab.AIM To explore the predictive value of BMI regarding the pathologic response following preoperative chemotherapy for CRLMs.METHODS A retrospective analysis was performed in 126 consecutive patients with CRLM who underwent hepatectomy following preoperative chemotherapy at four different hospitals from October 2019 to July 2023.Univariate and multivariate logistic regression models were applied to analyse potential predictors of tumour pathological response.The Kaplan-Meier method with log rank test was used to compare progression-free survival(PFS)between patients with high and low BMI.BMI<24.0 kg/m^(2) was defined as low BMI,and tumour regression grade 1-2 was defined as complete tumour response.RESULTS Low BMI was observed in 74(58.7%)patients and complete tumour response was found in 27(21.4%)patients.The rate of complete tumour response was significantly higher in patients with low BMI(29.7%vs 9.6%,P=0.007).Multivariate analysis revealed that low BMI[odds ratio(OR)=4.56,95%confidence interval(CI):1.42-14.63,P=0.011],targeted therapy with bevacizumab(OR=3.02,95%CI:1.10-8.33,P=0.033),preoperative carcinoembryonic antigen level<10 ng/mL(OR=3.84,95%CI:1.19-12.44,P=0.025)and severe sinusoidal dilatation(OR=0.17,95%CI:0.03-0.90,P=0.037)were independent predictive factors for complete tumour response.The low BMI group exhibited a significantly longer median PFS than the high BMI group(10.7 mo vs 4.7 mo,P=0.011).CONCLUSION In CRLM patients receiving preoperative chemotherapy,a low BMI may be associated with better tumour response and longer PFS.
文摘BACKGROUND Multiple primary carcinomas(MPCs)are defined as two or more independent primary cancers that occur simultaneously or sequentially in the same individual.Synchronous MPCs are rarer than solitary cancers or metachronous MPCs.Accurate diagnoses of synchronous MPCs and the choice of treatment are critical for successful outcomes in these cases.CASE SUMMARY A 64-year-old patient presented with dysphagia,without obvious cause.A diagnosis of synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis was confirmed based on examination and laboratory results.After multi-disciplinary consultations,combination chemotherapy(a 3-wk cycle with oxaliplatin 212 mg administered on day 1 and capecitabine 1.5 g twice daily on days 1-14)and esophageal cancer radiotherapy were initiated.Based on the results of genetic testing,we switched to a regimen of leucovorin+fluorouracil+oxaliplatin and cetuximab regimen for 8 cycles.Subsequently,capecitabine and bevacizumab were administered until the most recent follow-up,at which the tumor remained stable.CONCLUSION Successful cetuximab chemotherapy treatment provides a reference for the nonoperative and homogeneous treatment of different pathological types of synchronous MCPs.
