Objective To compare the survival outcomes and adverse events of patients with locally advanced cervical cancer (LACC) who received platinum monotherapy with concurrent chemoradiation therapy (CCRT) versus platinum-based dual drug therapy with CCRT. Method All relevant literature was screened form the PubMed, EMBASE, Web of Science, The Cochrane Library and other databases from their establishment to October 2020. The main endpoint indicators included overall survival (OS) and progression-free survival (PFS). Grade 3 and above adverse events induced by chemotherapy were also compared. Results This study involved 17 literature and 4,106 patients. There were 2,066 patients treated with CCRT with platinum-based dual drug therapy and 2,040 patients received CCRT with platinum monotherapy. Meta-analysis results showed that, compared to CCRT with platinum monotherapy, OS (HR = 0.68, 95% CI 0.58–0.79) and PFS (HR = 0.67, 95% CI 0.58–0.77) of LACC patients were significantly improved by CCRT with platinum-based dual drug therapy. In addition, CCRT with platinum-based dual drug therapy led to more adverse reactions such as neutropenia (OR = 4.92, 95% CI 3.55–6.84), anemia (OR = 1.99, 95% CI 1.17–3.39), diarrhea (OR = 1.70, 95% CI 1.30–2.22), leukopenia (OR = 2.42, 95%CI 1.84–3.17), thrombocytopenia (OR = 2.87, 95%CI 1.44–5.72), etc. Conclusion CCRT with platinum-based dual drug therapy improved OS and PFS of LACC patients relative to the CCRT with platinum monotherapy. But it also increased the adverse reactions caused by multiple chemotherapy drugs. Thus, it is crucial to select a proper chemotherapy regimen based on the actual tolerance of patients in clinical practice.
