BACKGROUND Patients with resectable gastric adenocarcinoma accompanied by vascular cancer thrombus(RGAVCT)have a poor prognosis,with a 5-year survival rate ranging from 18.42%-53.57%.These patients need a reasonable postoperative treatment plan to improve their prognosis.AIM To determine the most effective postoperative chemotherapy regimen for patients with RGAVCT.METHODS We retrospectively collected the clinicopathological data of 530 patients who un-derwent radical resection for gastric cancer between January 2017 and January 2022 and who were pathologically diagnosed with gastric adenocarcinoma with a choroidal cancer embolus.Fur-thermore,we identified the high-risk variables that can influence the prognosis of patients with RGAVCT by asse-ssing the clinical and pathological features of the patients who met the inclusion criteria.We also assessed the significance of survival outcomes using Mantel-Cox univariate and multivariate analyses.The subgroups of pa-tients with stages I,II,and III disease who received single-,dual-,or triple-drug regimens following surgery were analyzed using SPSS 25.0 and the ggplot2 package in R 4.3.0.RESULTS In all,530 eligible individuals with RGAVCT were enrolled in this study.The median overall survival(OS)of patients with RGAVCT was 24 months,and the survival rates were 80.2%,62.5%,and 42.3%at 12,24,and 59 months,respectively.Preoperative complications,tumor size,T stage,and postoperative chemotherapy were identified as independent factors that influenced OS in patients with RGAVCT according to the Cox multivariate analysis model.A Kaplan-Meier analysis revealed that chemotherapy had no effect on OS of patients with stage I or II RGAVCT;however,chemotherapy did have an effect on OS of stage III patients.Stage III patients who were treated with chemotherapy consisting of dual-or triple-agent regimens had better survival than those treated with single-agent regimens,and no significant difference was observed in the survival of patients treated with chemo-therapy consisting of dual-or triple-agent regimens.CONCLUSION For patients with stage III RGAVCT,a dual-agent regimen of postoperative chemotherapy should be recom-mended rather than a triple-agent treatment,as the latter is associated with increased frequency of adverse events. 展开更多

Objective The aim of this study was to investigate the effect of adjuvant chemotherapy (AC) on theprognosis of patients with ypT0-3N0 rectal cancer undergoing neoadjuvant chemoradiotherapy.Methods The study participants were 110 patients with locally advanced rectal cancer. Thirty-fourpatients did not receive postoperative AC treatment, and the other 76 patients received postoperative ACtreatment. The differences in the 5-year overall survival (OS) and disease-free survival (DFS) between thetwo groups were compared.Results Age was an important determinant of the patients’ decision to undergo postoperative treatment.Patients who did not receive AC treatment were significantly older than those who received AC treatment(P < 0.05). The tumor location (distance above anal margin) in the AC group was significantly larger thanthat in the non-AC group (P < 0.05). Moreover, there was no significant difference in the 5-year DFS andOS between the two groups. Postoperative AC did not significantly improve the prognosis of patients withrectal cancer. Age, tumor differentiation, and the number of resected lymph nodes were independent factorsaffecting the OS of patients (P < 0.05). Older patients, patients with lower degree of tumor differentiation,and patients with <12 resected lymph nodes showed worse prognosis (P < 0.05).Conclusion Patients with rectal cancer whose ypT0-3N0 stage is reduced after neoadjuvantchemoradiotherapy, especially those without adverse prognostic factors, do not need AC after surgery. 展开更多

Gastric cancer is an aggressive malignancy that may metastasize through the bloodstream to the liver,through lymphatics to regi onal lymph n odes,or by pen etratio n of the perit on eal lining of the stomach to result in seed ing of the abdom inal and pelvis surfaces.Peritoneal metastases are the most common mode of cancer dissemination.Technologies to prevent or treat perit on eal metastases from adva need gastric can cer are prese nted in this manu script.The world's literature,both recent and over the past three decades,was reviewed in order to identify publications that present information regarding gastric cancer peritoneal metastases.Over one dozen randomized controlled trials to test perioperative chemotherapy for prevention of peritoneal metastases were reviewed.All of the trials performed with regional chemotherapy during or shortly after gastrectomy were positive.The clinical data regarding the treatment of peritoneal metastases diagnosed at the time of primary can cer resecti on or in follow-up were reviewed.Neoadjuva nt in traperit on eal and systemic chemotherapy shows that some long-term survivors occur after these treatments were combined with cytoreductive surgery and gastrectomy.Similar treatments are advocated for primary gastric cancer with cytology positive for gastric cancer but no visible implants.Surgery for gastric cancer should be combined with perioperative systemic and regional chemotherapy in order to maximally benefit patients with this disease by reducing the negative impact of peritoneal metastases on survival. 展开更多
