초록

Background: Whether concurrent chemotherapy treatment is superior to radiotherapy alone as an adjuvant regimen for postoperative cervical carcinoma with risk factors remains controversial. Materials and Methods: A literature search strategy examined Pubmed, Embase, the Cochrane Library, the China National Knowledge Internet Web, the Chinese Biomedical Database and the Wanfang Database. Article reference lists and scientific meeting abstracts were also screened. Controlled trials comparing concurrent chemoradiotherapy versus radiotherapy alone in postoperative cervical cancer were included. The methodological quality of non-randomized controlled trials was evaluated using the Newcastle-Ottawa Scale. Randomized controlled studies were evaluated with the Cochrane handbook. A meta-analysis was performed with RevMan 5.3. Results: A total of 1,073 patients from 11 clinical trials were analysed, with 582 patients in the concurrent chemoradiotherapy group and 491 patients in the radiotherapy group. Hazard ratios (HR) of 0.47 (95% CI 0.31-0.72) and 0.50 (95% CI 0.35-0.72) were observed for overall survival and progression-free survival, indicating a benefit from the additional use of concurrent chemotherapy. Subgroup analyses demonstrated that cervical cancer with high risk factors significantly benefitted from concurrent chemotherapy when examining overall survival (HR 0.44, 95% CI 0.28-0.67) and progression-free survival (HR 0.48, 95% CI 0.33-0.70), but patients with intermediate risk factors showed no benefit from concurrent chemotherapy in overall survival (HR 1.72, 95% CI 0.28-10.41) and progression-free survival (HR 1.09, 95% CI 0.19-6.14). No significant differences were observed for grade 3-4 anaemia (risk ratio (RR) 3.87, 95% CI 0.69-21.84), grade 3-4 thrombocytopenia (RR 3.04, 95% CI 0.88-10.58), grade 3-4 vomiting or nausea (RR 1.71, 95% CI 0.27-10.96), or grade 3-4 diarrhoea (RR 1.40, 95% CI 0.69-2.83). Significant differences were observed for grade 3-4 neutropenia in favour of the radiotherapy group (RR 7.23, 95% CI 3.94-13.26). Conclusions: In conclusion, concurrent chemoradiotherapy improves survival in postoperative cervical cancer with high risk factors but not in those with intermediate risk factors.
