To verify the role of consolidation chemotherapy after concurrent chemoradiotherapy for bulky and locally advanced cervical cancer, a meta-analysis was performed. Based on articles published up to Jun 2020 a literature search in PubMed, EMBASE and Cochrane Library was conducted to identify eligible studies. A total of 4 articles consisting of 1659 patients were enrolled. The pooled results revealed that overall survival (OS) of patients treated with consolidation chemotherapy after concurrent chemoradiotherapy (CCRT + CT) was significantly superior to concurrent chemoradiotherapy (CCRT) alone (HR = 0.78, 95% CI: 0.69–0.88,  p  &lt; .0001). The meta-analysis reviewed that the progression-free survival rate (PFS) of patients treated with CCRT + CT was significantly superior to CCRT alone (HR = 0.80, 95% CI: 0.73–0.87,  p  &lt; .00001). The pooled results revealed a significant reduction of local recurrence rate for the CCRT + CT group (RR = 0.66, 95% CI: 0.55–0.79,  p  &lt; .00001). The pooled meta-analysis also showed a significant reduction of distant recurrence rate for the CCRT + CT group (RR = 0.55, 95% CI: 0.44–0.69,  p  &lt; .00001). The pooled results of grade 3/4 bone marrow suppression were calculated as OR and presented with a 95% CI (OR = 15.85; 95% CI: 9.48, 26.5,  p  &lt; .00001), indicating patients who received CCRT + CT are more likely to suffer 3/4 bone marrow suppression than those treated with CCRT alone. In conclusion, patients who received chemoradiation with consolidation chemotherapy showed a significantly longer PFS, longer OS, lower local recurrence rate and distant recurrence rate compared to traditional concurrent chemoradiotherapy.Impact statementWhat is already known on this subject?  Since CCRT was recommended as the standard treatment for cervical cancer, there was still a 20–30% chance of local recurrence, and 18–25% of distant recurrence for cervical cancer patients. Aiming to completely eradicate potential undetected micrometastases, consolidation chemotherapy came into the area of interest. We conducted a meta-analysis to verify the role of consolidation chemotherapy in cervical cancer.What do the results of this study add?  The addition of consolidation CT resulted in a longer overall survival rate (OS) and progression-free survival rate (PFS), mainly due to control of local and distant relapses, especially the latter one. Toxicity followed consolidation CT increased but still clinically manageable.What are the implications of these findings for clinical practice and/or further research?  In the future, we need more clinical studies with high quality to verify the role of consolidation CT in cervical cancer, and further to optimise the criteria for it.
