Impact of different therapies on the survival of patients with stage I-IIA cervical cancer with intermediate risk factors.

Abstract

BackgroundThe aim of this study was to determine the effects of different therapies on patients with cervical cancer (CC) with intermediate risk factors.MethodsClinicopathological data of 596 patients diagnosed with stage I–IIA CC at the Obstetrics and Gynecology Hospital of Fudan University between January 2013 and November 2015 were retrospectively reviewed. Of the patients, 500 patients received adjuvant therapy including chemotherapy (CT), radiotherapy (RT), and sequential chemotherapy and radiotherapy (CT + RT). Patients who displayed at least one intermediate risk factor number were screened.ResultsThe median follow-up was 62 months. The 5-year progression-free survival (PFS) and overall survival (OS) of the entire cohort were 90.4% and 90.9%, respectively. Univariate analysis showed that tumor stage, tumor size, pathological type, lymphovascular space invasion, and numbers of medium risk factors were not risk factors for early-stage CC. Compared with the control group, patients who received CT, RT, or CT + RT showed improved PFS and OS (P<0.05). The RT group had lower PFS and OS than the CT and CT + RT groups (P<0.05). Among the 318 patients with a single intermediate risk factor, 297 patients received CT, RT, and CT + RT benefit from adjuvant therapy (P<0.05). Of the 253 patients with high-risk factors, 220 patients received CT, RT and CT + RT get improved PFS and OS (P<0.05).ConclusionsPatients who received adjuvant therapy had better postoperative outcomes than those who did not receive adjuvant therapy. Patients had CT alone or CT combined with RT had better efficacy than those had RT alone.
