Poor PFS was correlated with high TET3 mRNA expression level for all ovarian carcinoma patients (HR = 1.23 (1.01–1.49), P = 0.038, n = 614, Additional file 2: Figure S2A), and for serous adenocarcinoma patients (HR = 1.4 (1.13–1.74), P = 0.0022, n = 346, Additional file 2: Figure S2B). The gene discussed is TET3; the disease is serous adenocarcinoma.
