The predictive role of CA- 125 value in early stage endometrioid endometrial cancer

Abstract

Objective: We aimed to evaluate the prognostic role of preoperative serum cancer antigen 125 (CA-125) in endometrioid endometrial cancer for determining the cut-off values for clinicopathological factors.
 Study design: 161 patients were included in the study. The inclusion criteria were histopathological confirmation of endometrioid endometrial cancer and patients with CA-125 levels measured at most ten days before surgery. The association between CA-125 value and clinicopathological variables were analyzed. Receiver operating characteristic curve statistical tests with clinicopathological factors were used to determine the cut-off values and the prognostic role of CA-125.
 Results: The median value of CA-125 level was 15.4 (3, 2-577) IU/L. These CA-125 cut-off values ranged from 14.30 to 18.67 IU/L (sensitivity 53%– 100%, specificity 30%–59%). The statistical analysis showed a significant relation between CA-125 value and stage and pelvic-paraaortic lymph nodes metastasis. The average life expectancy of patients with CA-125 ≥15.4 was 102.8±5.9 months, whereas that of patients with CA-125
