Comparison of two platinum-containing chemotherapy regimens in the treatment of advanced cervical cancer with concurrent chemoradiotherapy.

ABSTRACT

OBJECTIVE: The present study aims to compare the efficacy and side effects of a platinum-containing combination regimen and platinum single-drug concurrent chemoradiotherapy (CCRT) in patients with advanced cervical cancer (CC) and to understand the prognostic factors in patients with CC. METHODS: A total of 108 cases of CC treated in Wenzhou Central Hospital were retrospectively selected. Patients in the monotherapy (single-drug) group received external pelvic radiotherapy (RT) and platinum-based single-drug chemotherapy (CT). Patients in the combined group received external pelvic RT and platinum-containing CT. The efficacy, CCRT time, 3-year survival rate after treatment and side effects were compared between the two groups, and the prognostic factors were analysed. RESULTS: The total effective rate was 74.07% in the monotherapy group and 72.22% in the combined group (p = .828). The incidences of myelosuppression, gastrointestinal reaction and abnormal liver function in the grades III-IV combined group were significantly higher than those in the monotherapy group (p < .001; p = .236; p = .022). Furthermore, the CCRT time was significantly longer in the combined group than in the monotherapy group, and the 3-year overall survival (OS) was 81.48% in the monotherapy group and 79.63% in the combined group (p = .643; p = .808). The older the age was, the higher the serum squamous cell carcinoma antigen (SCC-Ag) value before treatment and the shorter the progression-free survival time. In addition, the older the adenocarcinoma (AC) was, the shorter the OS. CONCLUSION: The efficacy of the two regimens in the treatment of advanced CC was similar. However, the side effects increased significantly during combined treatment. PROGNOSTIC FACTORS A higher patient age, having an AC and stage of IIIa and a high SCC-Ag value before treatment resulted in a relatively low survival rate.
