[目的]探讨胃癌D2根治术后化疗起始时间与患者预后的关系。[方法]对我院2007~2011年间298例胃癌D2根治术后接受辅助化疗的患者进行了随访及系统分析。根据手术距辅助化疗开始的时间(≤45d和>45d)分析化疗起始时间与预后间的关系。[结果]298例患者中化疗开始时间≤45d,233例(78%),开始时间>45d65例(22%)。全组患者3年生存率为55.3%,5年生存率为9.6%。多因素分析显示化疗起始时间是胃癌患者的独立预后因素。[结论 ]胃癌D2根治术后最佳化疗开始时间应在45d内,延迟辅助化疗开始时间(>45d)可能与患者生存率降低有关。
[Objective] To investigate the relationship between the initiation of chemotherapy and the prognosis of patients after radical gastrectomy of gastric cancer. [Methods] The follow-up and systematic analysis of 298 patients who received adjuvant chemotherapy after radical gastrectomy of D2 gastric cancer from 2007 to 2011 in our hospital. The relationship between the initiation of chemotherapy and the prognosis was analyzed according to the time from the start of adjuvant chemotherapy (≤45d and> 45d). [Results] Among the 298 patients, the onset time of chemotherapy was ≤ 45 days, 233 cases (78%), and the start time> 45 days (65%) (22%). The 3-year overall survival rate was 55.3% and the 5-year survival rate was 9.6%. Multivariate analysis showed that chemotherapy initiation time was an independent prognostic factor in patients with gastric cancer. [Conclusion] The optimal chemotherapy start time should be within 45 days after D2 radical gastrectomy, and the delayed start of adjuvant chemotherapy (> 45 days) may be related to the decrease of patient survival rate.
