In multivariable analysis, DACH2 remained an independent prognostic factor in patients with serous carcinoma for both OCSS (HR = 2.01, 95% CI 1.05-3.85, p = 0.035) and OS (HR = 2.13, 95% CI 1.12-4.08, p = 0.022), but not in the full cohort (Table 2). This evidence concerns the gene DACH2 and serous adenocarcinoma.
