Postoperative Adjuvant Treatments for Cervical Cancer: A Network Meta-analysis
Abstract
To perform a comprehensive network meta-analysis assessing the efficacy and safety of five postoperative adjuvant therapies (PATs) for early-stage cervical cancer, comparing their effects on survival and adverse outcomes to identify the therapy with the most significant survival benefit. We comprehensively searched PubMed, Web of Science, the Cochrane Library, Embase, CNKI, VIP, Wanfang, and CBM for randomized controlled trials (RCTs) on PATs-including concurrent chemoradiotherapy (CCRT), radiotherapy (RT), chemotherapy (CT), sequential chemoradiotherapy (SCRT), and consolidation chemotherapy followed by CCRT (CCRT+CT)-in cervical cancer patients from inception to October 2024. Study bias was assessed with the Cochrane ROB.2. A Bayesian random-effects network meta-analysis was conducted for indirect comparisons, with τ² used to evaluate heterogeneity. Treatment rankings were generated using the SUCRA curve, and evidence certainty was assessed with the CINeMA framework. Nineteen RCTs with a total of 2,937 patients met the inclusion criteria. In our network meta-analysis, CCRT+CT showed the most significant benefit for OS (HR 0.46, 95% CI 0.28-0.71, SUCRA 95%, high-certainty evidence), followed by SCRT (1.59, 1.04-2.33, 65%, high-certainty evidence) and CCRT alone (0.71, 0.5-0.95, 48%, moderate-certainty evidence). For DFS, CCRT+CT again showed a significant advantage over RT (0.48, 0.23-0.91, 88%, low-certainty evidence). In recurrence analysis, CCRT+CT demonstrated the most…
