ABSTRACT
Purpose@#This study aimed to evaluate the survivals of patients with metastatic or recurrent gastric cancer (MRGC) over a period of 16 years and to investigate the recent changes in chemotherapy patterns. @*Materials and Methods@#A total of 5,384 patients who received chemotherapy for MRGC between 2000 and 2015 were analyzed. The analysis focused on a comparison of the first-line chemotherapy between four periods 2000–2003 (period 1), 2004–2007 (period 2), 2008–2011 (period 3), and 2012–2015 (period 4). @*Results@#There were 880 patients (16%) in period 1, 1,573 (29%) in period 2, 1,435 (27%) in period 3, and 1,496 (28%) in period 4. Cytotoxic doublet-based therapy was the most commonly used (78%) first-line chemotherapy, and the combination of trastuzumab and doublet chemotherapy was provided to 288 patients. The OS rates at 12 and 24 months were steadily improved as follows 39.2% and 14.6% in period 1, 43.5% and 17.6% in period 2, 50.3% and 20.6% in period 3, and 51.7% and 24.1% in period 4, respectively (p < 0.001). Among the patients who received the doublet-based chemotherapy, the median OS of those who received trastuzumab was 18.0 months (95% CI, 15.5–20.6), while that of those who received other doublet therapies was 11.2 months (95% CI, 10.8–11.6). @*Conclusion@#The OS was improved over time with advancements in chemotherapy, particularly the introduction of the anti-HER2–targeted agent, which contributed to the increase in the number of long-term survivors and established the superiority of OS for the treatment of MRGC.
