Core Tip	In gastric cancer patients mortality from recurrence peaked in the first two years after curative gastrectomy and then declined. The prognostic significance of risk factors was not stable, as the effect of T and N decreased with time, while the effect of histology became apparent after two years. Advancing age was associated with increased post-operative mortality. Hence, the proportional hazards assumption of the Cox model was violated. A possible solution was to split survival analysis in the first two years of follow-up and subsequent years. By comparison, overall mortality and prognostic significance of risk factors was rather stable in a cohort of type 2 diabetic patients.
