Abstract
Objectives: To investigate the relationship between alpha-folate receptor (α-FR) expression levels to the clinico-pathologic features and outcomes of patients with serous ovarian carcinoma.
Methods: Semi-quantitative reverse-transcription polymerase chain reaction detected α-FR expression in 91 patients with serous ovarian carcinoma. Clinico-pathologic parameters and biomarkers, including FIGO stage, tumor grade, optimal surgery, lymph nodes metastasis, pre-operative serum CA-125, and α-FR expression levels in cancerous tissues to evaluate disease-free interval (DFI) and overall survival (OS), were analyzed.
Results: There were 4, 6, 65, and 16 patients with stages I, II, III, and IV ovarian carcinoma, respectively. Forty (44%) underwent optimal debulking surgery. Patients with advanced stages (stage I: 0.451, stage II: 0.415, stage III: 0.652, stage IV: 0.768, p=0.004) or those with sub-optimal debulking surgery (optimal: 0.490, sub-optimal: 0.766, p=0.003) had significantly higher α-FR expression levels compared to those with early stages or optimal debulking surgery. In prognostic analysis, high α-FR expression level (HR: 2.70 (1.20-6.05), p=0.016) was an independent poor prognostic factor for DFI and had a negative impact on OS with marginal significance (HR: 3.51 (0.93-13.29), p=0.065) using multivariate analyses.
Conclusions: Patients of serous ovarian carcinoma with high α-FR expression in cancerous tissue have shorter DFI and OS. α-FR may be a potential biomarker for predicting the outcome of serous ovarian carcinoma patients.
