Alpha1B adrenoceptor expression is a marker of reduced survival and increased tumor recurrence in patients with endometrioid ovarian cancer

Table 3 A Cox regression analysis was performed to test the independence of tumor alpha1B protein expression as a biomarker compared to tumor grade, clinical stage and chemotherapy treatment
