The effect of long-term traditional Chinese medicine treatment on disease-free survival of postoperative stage I-III lung cancer patients:a retrospective cohort study

Objective:Traditional Chinese medicine(TCM)has been extensively used as one of popular alternative therapies for several cancers.However,it remains unclear whether TCM treatment is associated with longer survival in lung cancer patients.In this study,we explored the effect of long-term TCM treatment on patients with different stages of lung cancer.Methods:All information of lung cancer patients with stage I-III disease from January 2007 to September 2015 was collected for this retrospective cohort study.Those who were treated with TCM after surgery were divided into TCM group and the others were into the non-TCM group(control group).All patients were regularly followed up by clinic appointment or phone,and all survival data were collected from databases after the last follow-up in October 2017.Results:A total of 575 patients were included in this study,with 299 patients in the TCM group and 276 in the control group.For all patients,5-year disease-free survival(DFS)was 62.2% in TCM group and 42.1% in the control group,and 6-year DFSs were 51.8% and 35.4%,respectively(HR=0.51,95% CI:0.40 to 0.66,log-rank P≤0.001).For patients with stage I,5-year DFSs were 83.7%(TCM group)and 57.5%(control group)and 6-year DFSs were 73.7% and 51.9%,respectively(HR=0.30,95% CI:0.18 to 0.50,log-rank P≤0.001).For patients with stage II in the TCM group and the control group,5-year DFSs were 59.4% and 17.6% and 6-year DFSs were 44.7% and 17.6%,respectively(HR=0.31,95% CI:0.19 to 0.52,log-rank P≤0.001),and for patients with stage III,5-year and 6-year DFSs in the TCM group were 18.7% and 12.5% compared with 28.4% and 20.3% in the control group(HR=1.06,95% CI:0.72 to 1.56,log-rank P=0.76).Conclusions:This study demonstrated that long-term TCM treatment as an adjuvant therapy is able to improve the DFS of postoperative stage I-III lung cancer patients,especially in patients with stage I and II disease.However,these observational findings need being validated by large sample randomized controlled trials.

Prognostic factors for disease-free survival in postoperative patients with hepatocellular carcinoma and construction of a nomogram model

BACKGROUND Hepatocellular carcinoma(HCC)is the most common type of liver cancer and has a high risk of invasion and metastasis along with a poor prognosis.AIM To investigate the independent predictive markers for disease-free survival(DFS)in patients with HCC and establish a trustworthy nomogram.METHODS In this study,445 patients who were hospitalized in The First Affiliated Hospital of Anhui Medical College between December 2009 and December 2014 were retrospectively examined.The survival curve was plotted using the Kaplan–Meier method and survival was determined using the log-rank test.To identify the prognostic variables,multivariate Cox regression analyses were carried out.To predict the DFS in patients with HCC,a nomogram was created.C-indices and receiver operator characteristic curves were used to evaluate the nomogram’s performance.Decision curve analysis(DCA)was used to evaluate the clinical application value of the nomogram.RESULTS Longer DFS was observed in patients with the following characteristics:elderly,I–II stage,and no history of hepatitis B.The calibration curve showed that this nomogram was reliable and had a higher area under the curve value than the tumor node metastasis(TNM)stage.Moreover,the DCA curve revealed that the nomogram had good clinical applicability in predicting 3-and 5-year DFS in HCC patients after surgery.CONCLUSION Age,TNM stage,and history of hepatitis B infection were independent factors for DFS in HCC patients,and a novel nomogram for DFS of HCC patients was created and validated.

High level of preoperative carbohydrate antigen 19-9 is a poor survival predictor in gastric cancer

AIM:To assess the clinical significance and the prognostic value of preoperative serum carbohydrate antigen 19-9(CA 19-9)level in gastric cancer.METHODS:Between January 2005 and December2006,1960 patients underwent surgery for histologically confirmed gastric cancer.Of these,163 patients had elevated serum levels of CA 19-9 preoperatively,and1628 patients had normal serum levels of CA 19-9 preoperatively.For this study,325 patients were selected from the group of 1628 patients by age,sex,and cancer stage to serve as controls.Statistically significant differences in survival rates were calculated using the log-rank test.A P value less than 0.05 was considered statistically significant and was determined using SAS software.RESULTS:The baseline characteristics showed some differences between the two groups with regard to histology.Overall survival(OS)in the elevated and nonelevated group was 37.90 and 68.67 mo,respectively(P<0.001).N stage(P=0.001)was a significant predictor of disease-free survival by multivariate analysis.Also,N stage(P<0.001),and the presence of peritoneal metastasis(P<0.001)remained independent factors in predicting OS by multivariate analysis.Additionally,preoperative serum CA 19-9 levels were significantly associated with OS in univariate(P=0.009)and multivariate(P=0.021)analyses.CONCLUSION:Serum CA 19-9 can be considered an independent prognostic factor in predicting OS in patients anticipating surgery for gastric cancer.

Recurrence and survival after surgery for pancreatic cancer with or without acute pancreatitis

BACKGROUND In pancreatic cancer,acute pancreatitis(AP)is a serious morbidity,but its negative effect on long-term outcomes remains to be elucidated.AIM To investigate the effects of AP on the tumor recurrence pattern of pancreatic ductal adenocarcinoma(PDAC)and tumor-specific survival.METHODS The medical records of 219 patients with curative pancreatectomy for pancreatic cancer at the Pancreatic Surgery Center of West China Hospital from July 2012 to December 2016 were analyzed retrospectively.The severity of acute pancreatitis was classified according to the Atlanta classification of AP.The patient demographics and tumor characteristics were assessed.Early recurrence was defined as a relapse within 12 mo after surgery.Overall and disease-free survival and recurrence patterns were analyzed.Mild acute pancreatitis was excluded because its negative effects can be negligible.RESULTS Early recurrence in AP group was significantly higher than in non-AP group(71.4%vs 41.2%;P=0.009).Multivariate analysis of postoperative early recurrence showed that moderate or severe AP was an independent risk factor for an early recurrence[odds ratio(OR):4.13;95%confidence interval(CI):1.41-12.10;P=0.01].The median time to recurrence was shorter in patients with AP than in those without(8.4 vs 12.8 mo;P=0.003).Multivariate analysis identified AP as an independent prognostic factor for overall survival[relative risk(RR):2.35;95%CI:1.45-3.83]and disease-free survival(RR:2.24;95%CI:1.31-3.85)in patients with PDAC.CONCLUSION Patients with moderate or severe acute pancreatitis developed recurrences earlier than those without.Moderate or severe AP is associated with shorter overall and disease-free survival of patients with PDAC.

Is there an optimal time to initiate adjuvant chemotherapy to predict benefit of survival in non-small cell lung cancer?

Objective: Adjuvant chemotherapy(AC) after curative resection is known to improve the survival of patients with non-small cell lung cancer(NSCLC); however, few studies have reported the correlation between the time to initiation of AC(TTAC) and survival in NSCLC patients.Methods: The clinical data of 925 NSCLC patients who received curative resection and post-operative AC at the Cancer Hospital of Chinese Academy of Medical Sciences between 2003 and 2013 were retrospectively analyzed.TTAC was measured from the date of surgery to the initiation of AC. Disease-free survival(DFS) was defined as the duration from surgery to the time of tumor recurrence or last follow-up evaluation. The optimal cut-off value of TTAC was determined by maximally selected log-rank statistics. The DFS curve was estimated using the Kaplan-Meier method, and the Cox proportional hazards regression model was used to identify risk factors independently associated with DFS. Propensity score matching(PSM) was performed for survival analysis using the match data.Results: The optimal discriminating cut-off value of TTAC was set at d 35 after curative resection based on which the patients were assigned into two groups: group A(≤35 d) and group B(>35 d). There was no significant difference in the DFS between the two groups(P=0.246), indicating that the TTAC is not an independent prognostic factor for DFS. A further comparison continued to show no significant difference in the DFS among 258 PSM pairs(P=0.283).Conclusions: There was no significant correlation between the TTAC and DFS in NSCLC patients. Studies with larger samples are needed to further verify this conclusion.

Long-term survival outcome of laparoscopic liver resection for hepatocellular carcinoma

Long-term survival is the most important outcome measurement of a curative oncological treatment.For hepatocellular carcinoma(HCC),the long-term disease-free and overall survival of laparoscopic liver resection(LLR)is shown to be non-inferior to the current standard of open liver resection(OLR).Some studies have reported a superior long-term oncological outcome in LLR when compared to OLR.It has been argued that improvement of visualization and instrumentation and reduced operative blood loss and perioperative blood transfusion may contribute to reduced risk of postoperative tumor recurrence.On the other hand,since most of the comparative studies of the oncological outcomes of LLR and OLR for HCC are non-randomized,it remained inconclusive as to whether LLR confers additional survival benefit compared to OLR.Despite the paucity of level 1 evidence,the practice of LLR for HCC has gained wide-spread acceptance due to the reproducible improvements in the perioperative outcomes and non-inferior oncological outcomes demonstrated by large-scaled,matched comparative studies.Meta-analyses of the outcomes of these studies by multiple systematic reviews have also returned noncontradictory conclusions.On the basis of a theoretical advantage of LLR over OLR in preventing tumor recurrence,the current review aims to dissect from the current meta-analyses and comparative studies any evidence of such superiority.

Prognostic factors of survival and a new scoring system for liver resection of colorectal liver metastasis

BACKGROUND Hepatic resection has become the preferred treatment of choice for colorectal liver metastasis(CLM)patients.AIM To identify the prognostic factors and to formulate a new scoring system for management of CLM.METHODS Clinicopathologic and long-term survival data were analyzed to identify the significant predictors of survival by univariate and multivariate analyses with the Cox model.A clinical score was constructed based on the analysis results.RESULTS Three factors of worse overall survival were identified in the multivariate analysis.They were number of liver metastases≥5,size of the largest liver lesion≥4 cm,and the presence of nodal metastasis from the primary tumor.These three factors were chosen as criteria for a clinical risk score for overall survival.The clinical score highly correlated with median overall survival and 5-year survival(P=0.002).CONCLUSION Priority over surgical resection should be given to the lowest score groups,and alternative oncological treatment should be considered in patients with the highest score.

Impact of resection margins on long-term survival after pancreaticoduodenectomy for pancreatic head carcinoma

BACKGROUND The impact of resection margin status on long-term survival after pancreaticoduodenectomy(PD) for patients with pancreatic head carcinoma remains controversial and depends on the method used in the histopathological study of the resected specimens. This study aimed to examine the impact of resection margin status on the long-term overall survival of patients with pancreatic head carcinoma after PD using the tumor node metastasis standard.METHODS Consecutive patients with pancreatic head carcinoma who underwent PD at the Chinese People's Liberation Army General Hospital between May 2010 and May 2016 were included. The impact of resection margin status on long-term survival was retrospectively analyzed.RESULTS Among the 124 patients, R0 resection was achieved in 85 patients(68.5%), R1 resection in 38 patients(30.7%) and R2 resection in 1 patient(0.8%). The 1-and 3-year overall survival(OS) rates were significantly higher for the patients who underwent R0 resection than the rates for those who underwent R1 resection(1-year OS rates: 69.4% vs 53.0%;3-year OS rates: 26.9% vs 11.7%). Multivariate analysis showed that resection margin status and venous invasion were significant risk factors for OS.CONCLUSION Resection margin was an independent risk factor for OS for patients with pancreatic head carcinoma after PD. R0 resection was associated with significantly better OS after surgery.

Factors associated with levelⅢlymph nodes positive and survival analysis of its dissection in patients with breast cancer

Objective:Surgical resection remains the mainstream radical therapy in patients with breast cancer.Given that no consensus has been reached on the exact indication for levelⅢlymph node dissection,the aim of this study is to explore factors associated with levelⅢlymph nodes positive and survival analysis of its dissection in patients with breast cancer.Materials and methods:A retrospective study including 61 patients after levelⅠ-Ⅲdissection via a smaller incision of pectoralis major and 61 patients experiencing only levelⅠandⅡclearance was performed.Clinicopathological outcomes were compared initially and survival analysis was conducted subsequently.Results:No significant differences were presented in baseline and clinicopathological characteristics between the two groups.Ten(16.4%)patients’levelⅢnodes were proven positive after levelⅢdissection.Positive nodes in levelⅠandⅡlymph nodes over 9 was demonstrated as an independent predictor of levelⅢnodes positive(OR:200.75[95%CI:7.77e5187.19],p-0.001).Although the levelⅠ-Ⅲlymph node dissection group presented a seemingly better disease-free survival,statistical significance was not detected(p-0.21).Conclusions:This study revealed that having positive nodes in levelⅠandⅡlymph nodes over 9 was a risk factor of levelⅢlymph nodes positive.But levelⅢlymph node dissection does not offer definite survival benefit.

Evaluation of bacterial contamination and medium-term oncological outcomes of intracorporeal anastomosis for colon cancer:A propensity score matching analysis

BACKGROUND Although intracorporeal anastomosis(IA)for colon cancer requires longer operative time than extracorporeal anastomosis(EA),its short-term postoperative results,such as early recovery of bowel movement,have been reported to be equal or better.As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum,there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells.However,intraperitoneal bacterial contamination and medium-term oncological outcomes have not been clarified.abdominal cavity in IA.METHODS Of 127 patients who underwent laparoscopic colon resection for colon cancer from April 2015 to December 2020,75 underwent EA(EA group),and 52 underwent IA(IA group).After propensity score matching,the primary endpoint was 3-year disease-free survival rates,and secondary endpoints were 3-year overall survival rates,type of recurrence,surgical site infection(SSI)incidence,number of days on antibiotics,and postoperative biological responses.RESULTS Three-year disease-free survival rates did not significantly differ between the IA and EA groups(87.2%and 82.7%,respectively,P=0.4473).The 3-year overall survival rates also did not significantly differ between the IA and EA groups(94.7%and 94.7%,respectively;P=0.9891).There was no difference in the type of recurrence between the two groups.In addition,there were no significant differences in SSI incidence or the number of days on antibiotics;however,postoperative biological responses,such as the white blood cell count(10200 vs 8650/mm^(3),P=0.0068),C-reactive protein(6.8 vs 4.5 mg/dL,P=0.0011),and body temperature(37.7 vs 37.5℃,P=0.0079),were significantly higher in the IA group.CONCLUSION IA is an anastomotic technique that should be widely performed because its risk of intraperitoneal bacterial contamination and medium-term oncological outcomes are comparable to those of EA.

Genetic polymorphisms of autophagy-related gene 5 (ATG5) rs473543 predict different disease-free survivals of triple-negative breast cancer patients receiving anthracycline- and/or taxane-based adjuvant chemotherapy

Background:Autophagy plays a crucial role in chemotherapy resistance of triple-negative breast cancer(TNBC).Hence,autophagy-related gene 5(ATG5),an essential molecule involved in autophagy regulation,is presumably associated with recurrence of TNBC.This study was aimed to investigate the potential influence of single-nucleotide polymorphisms in ATG5 on the disease-free survival(DFS)of early-stage TNBC patients treated with anthracycline-and/or taxane-based chemotherapy.Methods:We genotyped ATG5 SNP rs473543 in a cohort of 316 TNBC patients treated with anthracycline-and/or taxane-based chemotherapy using the sequenom’s MassARRAY system.Kaplan-Meier survival analysis and Cox proportional hazard regression analysis were used to analyze the association between ATG5 rs473543 genotypes and the clinical outcome of TNBC patients.Results:Three genotypes,AA,GA,and GG,were detected in the rs473543 of ATG5 gene.The distribution of ATG5 rs473543 genotypes was significantly different between patients with and without recurrence(P=0.024).Kaplan-Meier survival analysis showed that patients carrying A allele of ATG5 rs473543 had an increased risk of recurrence and shorter DFS compared with those carrying the variant genotype GG in rs473543(P=0.034).In addition,after adjust-ing for clinical factors,multivariate Cox regression analyses revealed that the AA/GA genotype of rs473543 was an independent predictor for DFS(hazard risk[HR],1.73;95%confidence interval[CI],1.04-2.87;P=0.034).In addition,DFS was shorter in node-negative patients with the presence of A allele(AA/GA)than in those with the absence of A allele(P=0.027).Conclusion:ATG5 rs473543 genotypes may serve as a potential marker for predicting recurrence of early-stage TNBC patients who received anthracycline-and/or taxane-based regimens as adjuvant chemotherapy.

Prognostic factors for disease-free survival in patients with pancreatic ductal adenocarcinoma after surgery: a single center experience

Objective: To evaluate the risk factors for the disease-free survival (DFS) of pancreatic ductal adenocarcinoma (PDAC) patients after surgery, and to validate the clinical applicability and prognostic stratification of the 8th edition American Joint Committee on Cancer (AJCC) staging system. Methods: A cohort of 185 patients with PDAC who underwent surgical resection in the General Surgery Department of Peking University First Hospital from January 2010 to December 2017 was enrolled retrospectively. The clinicopathological characteristics and survival data were analyzed to find out risk factors correlated to DFS. The survival curves were calculated according to the 8th edition of AJCC staging system. Results:Among the 185 PDAC patients, 125 (67.6%) with pancreatic head carcinoma underwent pancreatoduodenectomy or total pancreatectomy, and 60 (32.4%) with tumors located in the pancreatic body and tail underwent distal pancreatectomy and splenectomy. R0 resection was achieved in 97 patients (52.4%), and the R1 and R2 resections rate was 44.9% and 2.7%, respectively. One hundred five patients (56.8%) received postoperative adjuvant chemotherapy. The median overall survival (OS) was 21 (95% confidence interval [CI] 17.7–24.3) months, and median DFS was 15 (95% CI 13.6–16.5) months. Univariate analysis showed that AJCC T and N staging, status of resection margin, grade of tumor differentiation, perineural invasion, intravascular cancer embolus, combined vascular resection, neutrophil-to-lymphocyte ratio (NLR)≥2, carcinoembryonic antigen ≥5ng/mL, carbohydrate antigen 19-9 (CA 19-9)≥400U/mL, and without postoperative adjuvant chemotherapy were correlated with shorter DFS. Furthermore, AJCC T3, N1 and N2 staging, R2 resection, low-grade or undifferentiated tumors, combined vascular resection, NLR≥2, CA 19-9≥400U/mL, and without postoperative adjuvant chemotherapy were independent risk factors for DFS. Both the DFS and OS curves were well separated by stage using the 8th staging classification. Conclusions: The 8th edition of AJCC T, primary tumor;N, regional lymph nodes;M, distant metastasis staging system could predict the prognosis of PDAC accurately. Patients with AJCC T3, N1 and N2 staging, R2 resection, low-grade or undifferentiated tumors, combined vascular resection, NLR≥2, CA 19-9≥400U/mL, and without postoperative adjuvant chemotherapy, have a significantly higher risk of tumor recurrence and shorter DFS after surgery. R0 resection and adjuvant chemotherapy could significantly prolong the DFS of PDAC patients.

Long-term disease-free survival in a dog with appendicular osteosarcoma

Postoperative prognosis is generally poor even with adjuvant chemotherapy in dogs with an appendicular osteosarcoma. The purpose of this report was to present the long-term disease-free survival time in a dog with appendicular osteosarcoma receiving amputation,adjuvant chemotherapy and adoptive immunotherapy. A 12-year-old spayed Golden retriever was referred to our hospital with a suspicion of osteosarcoma in right distal radius. The patient underwent the computed tomography (CT) and incisional biopsy on the next day after the first presentation. The CT revealed the osteolysis in the right distal radius and no metastases in the lungs and lymph nodes. The histopathologic diagnosis was made as an osteosarcoma. On the 13th day after,the patient underwent right forelimb amputation. Six doses of carboplatin (250 mg / m2) were postoperatively administered every 3 weeks. The intravenous infusion of lymphokine-activated killer (LAK) cells suspension was performed every 3 ~ 4 weeks after the adjuvant chemotherapy. At the time of our writing this abstract (on the 880thday after the first presentation),no recurrences and metastases were observed after the 32 transfers of LAK cells. In canine appendicular osteosarcoma,some reports have described that postoperative median survival times were 235 ~ 540 d with adjuvant chemotherapy. In our report,the disease free interval and survival time were prolonged compared with the previous reports. We strongly believed that early diagnosis and surgical intervention and adoptive immunotherapy had a great impact on the improvement of survival time in canine appendicular osteosarcoma.

目的探讨在非小细胞肺癌(NSCLC)中PD-L1及TGF-β表达水平,及其与NSCLC临床病理参数和术后无病生存期(DFS)的关系。方法收集81例NSCLC标本,采用免疫组化方法检测术后肿瘤组织中PD-L1、PD-1、Foxp3+和TGF-β蛋白的表达水平。结果81例患者中PD-L1阳性表达为46例(56.8%),阴性表达35例(43.2%)。TGF-β阳性36例(44.4%),阴性45例(55.6%)。PD-1阳性33例(40.7%),阴性48例(59.3%);Foxp3+阳性44例(54.3%),阴性37例(45.7%)。NSCLC中PD-L1蛋白表达与各临床病理参数无明显相关性。单因素分析发现T分期、TGF-β表达、PD-L1表达影响.SCLC术后DFS,具有统计学差异(P<0.05),多因素分析发现T分期、TGF-β表达、PD-L1表达是影响NSCLC术后DFS的独立因素(P<0.05)。PD-L1阳性表达组术后DFS为(21.000±1.429)个月,阴性表达组为(14.500±1.615)个月,两组有统计学差异(χ~2=6.930,P=0.008)。TGF-β阳性组PFS为(14.500±0.813)个月,阴性组为(21.000±1.639)个月,两组有统计学差异(χ~2=8.71,P=0.003)。结论非小细胞肺癌中PD-L1及TGF-β蛋白是预测NSCLC术后DFS的重要指标,且PD-L1表达越高预示术后DFS越长,而TGF-β则表达越高,预示术后DFS越短。
