Abstract

PurposeThere is currently a lack of research on preoperative prognostic analysis of early-stage cervical adenocarcinoma (ADC). The purpose of our study was to clarify whether preoperative serum tumor-marker levels were of prognostic value in early-stage ADC.Patients and MethodsWe performed a retrospective study of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IA1–IIA1 and pathology-proven invasive ADC. We evaluated the relationship between preoperative serum tumor-marker levels and clinicopathological characteristics, and identified the relative preoperative risk factors affecting disease-free survival (DFS) and overall survival (OS). The optimal cut-off point of meaningful tumor markers was determined by the analysis of receiver operating characteristics (ROC), and the accuracy of the results was evaluated by the area under the curve (AUC).ResultsElevated carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), squamous cell carcinoma antigen (SCC-Ag), alpha-fetoprotein (AFP), carbohydrate antigen 153 (CA153) and carbohydrate antigen 199 (CA199) were associated with certain clinicopathologic features of early-stage ADC. The combination of elevated serum CEA and CA125 was significantly associated with FIGO stage, body mass index (BMI) and LNM. Kaplan–Meier survival curve and Cox regression analyses revealed that CEA and CA125 might have significant prognostic implications in early-stage ADC patients, and the combination of elevated serum CEA and CA125 served as an independent predictor of early-stage ADC. The optimal cut-off point of serum CA125 for prediction DFS and OS was 32.60 U/mL and of serum CEA were 2.85 ng/mL and 2.05 ng/mL, respectively. The AUC showed that serum CEA was a moderate predictor of OS.ConclusionThe preoperative serum levels of CEA and CA125 might have significant prognostic implications in early-stage ADC patients. Combined preoperative serum CEA and CA125 levels independently predicted the prognosis of early-stage ADC.
