A Proposal of a Personalized Surveillance Strategy for Gastric Cancer: A Retrospective Analysis of 9191 Patients

Figure 2

9191 patients were distinguished into seven groups according to the seventh AJCC staging manual from IA to IIIC: (a) survival curves of seven groups and significant differences on survival were demonstrated. (b) HR curves of seven groups were demonstrated, and the curves of stages I and IIA were flatter than those of stages IIB and III, while those of stages IIB and III had an obvious peak in each curve. (c) The maxHR and the corresponding time were also estimated in each group, and it showed a monotonic increasing of the maxHR from stage IA to IIIC.
