Abstract

The present study aimed to determine the effect of the timing of treatment discontinuation on the prognosis of patients with advanced and recurrent gastric cancer chemotherapy. Between July 2014 and March 2017, 127 patients who underwent chemotherapy for advanced and recurrent gastric cancer at Ogaki Municipal Hospital (Ogaki, Japan) were examined. To determine factors associated with survival, multivariate analysis using the Cox proportional hazards model, and hazard ratios and their 95% confidence intervals (95% CI) were calculated. The reasons for discontinuation of last‑line chemotherapy and the last hospitalization prior to mortality were surveyed. Age (≤51 years), number of treatment lines (≤1 line), and days between last dose of the final chemotherapy regimen and death (≤79 days) were independently and significantly associated with survival in the multivariate analysis. Compared with patients who did not receive chemotherapy in the last 79 days of life, those who received chemotherapy in the last 79 days of life days had a hazard ratio of 1.858 (95% CI, 1.059‑3.261; P=0.031) for mortality. A decrease in the performance status was responsible for treatment discontinuation in 51 of 75 cases among patients who received chemotherapy in the last 79 days of life and 9 of 26 cases among patients who did not receive chemotherapy in this duration (P<0.001). Among patients who received chemotherapy in the last 79 days of life, 67 patients were hospitalized prior to mortality; among patients who did not receive chemotherapy in this duration, 15 patients were hospitalized prior to mortality (P<0.001). In conclusion, continuation of chemotherapy until just prior to mortality does not prolong the survival time in patients with advanced and recurrent gastric cancer.
