Kaplan-Meier relapse-free survival comparison of S100A1+ and S100A1− ovarian and endometrial cancer tissues. A, Relapse-free survival time plotted as a function of S100A1 staining of ovarian cancer tissues by subtype, as labeled. Endometrioid subtype, P = .004; other subtypes, not significant. B, Relapse-free survival time plotted as a function of S100A1 staining of endometrial endometrioid cancer. P = .0367. S100A1+, solid line; S100A1−, dashed line.
