Abstract

Background: The prognostic factors for survival in squamous cell carcinoma (SCCA) of vulva cancer such as groin node involvement, postmenopausal status, tumor size, margin status, tumor grade, lymph vascular space invasion (LVSI) were reported in the past. However, with limited data from Southeast - Asian population, the present study was conducted to evaluate the clinicopathological prognostic factors for survival outcomes of this disease after treatment with surgery. Methods: All SCCA vulva cancer patients who underwent surgery between January 2006 and December 2017 were reviewed. The clinicopathological factors were analyzed to identify the prognostic factors for the progression-free survival (PFS) and overall survival (OS) using the Kaplan- Meier method and Cox-Proportional Hazard model. Results: One hundred twenty-five patients were recruited. The independent poor prognostic factors for PFS were groin node-positive and pathologic tumor diameter of more than 25 mm. Whereas postmenopausal status and groin node positive were independent poor prognostic factors for OS. Conclusion: Groin node-positive was the only one independent poor prognostic factor for both PFS and OS. In addition, the tumor diameter longer than 25 mm. was independent poor prognostic factors for PFS while postmenopausal status was independent poor prognostic factors for OS. Special adjuvant treatment for patients with these factors should be further investigated.
