Background With the increasing availability of active agents, the importance of postprogression survival (PPS) has been recognised for several malignancies. However, little is known of PPS in advanced gastric cancer. Patients and methods A literature search identified 43 randomised trials in chemotherapy-naive patients with advanced gastric cancer. We partitioned overall survival (OS) into progression-free survival (PFS) and PPS, and then examined the correlation between median OS and either median PFS or median PPS. The correlation between differences in OS (ΔOS) and those in PFS (ΔPFS) between trial arms was also investigated. Results The average median OS was significantly longer in recent (2006 and later) trials than in older (2005 and earlier) trials (10.60 versus 8.64 months, P < 0.001), as was the average median PPS (5.34 versus 3.74 months, P = 0.001). Median PPS was correlated with median OS for all trials (r = 0.732), and this correlation was more pronounced in recent trials (r = 0.850). By contrast, the correlation between median PFS and median OS was less pronounced in recent trials (r = 0.282), as was that between ΔPFS and ΔOS (r = 0.365). Conclusion An increase in median PPS was found in accordance with an increase in median OS in recent trials compared with older trials for patients with advanced gastric cancer.
