Abstract
Background Cervical cancer ranks the third most common malignancy of women worldwide, and recurrence of cervical cancer treatment is the major concern. Carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), squamous cell carcinoma antigen (SCCA) and Glasgow Prognostic Score (GPS) were potential prognostic indicator for cervical cancer. However, none of these markers have been evaluated to predict post-relapse survival in recurrent cervical cancer after treatment based on real-world clinical data. Aim To evaluate biomarkers CEA, CA125, SCCA and Glasgow Prognostic Score (GPS) in predicting post-relapse survival in recurrent cervical cancer after treatment based on real-world clinical data. Results Among the 1607 patients, the majority of patients (75.5%) were non-smokers, and the majority of histologic type (68.3%) was squamous cell carcinoma. Except CEA, there were significant difference between different GPS groups in these markers. Areas under the curves (AUC) for GPS, CEA, CA125 and SCCA were 0.632, 0.617, 0.641 and 0.628, respectively. All clinicopathologic characteristics were significantly correlated with CA125. Higher levels of biomarkers and GPS had lower survival and GPS=2 and SCCA was an independent prognostic factor for survival (P=0.008 and P=0.010, respectively). Conclusions In real-world settings, GPS and tumor biomarkers, especially SCCA to independently predict post-recurrence survival in patients with recurrent cervical cancer.
