Abstract
Cervical cancer is a global health challenge in women. Neoadjuvant chemotherapy (NACT) is a recent prospect for alternative cervical cancer treatments. This study investigated the efficacy of NACT against resectable cervical cancer based on the medium and long-term survival of patients with the disease. We searched through PubMed, Web of Science, EBSCO and Cochrane Library for relevant reports published by June 2020. The primary outcomes were 3-year and 5-year progression-free survival (PFS) and overall survival (OS) of patients with resectable cervical cancer. Overall, 22 publications encompassing 5627 patients fulfilled the inclusion criteria. We found NACT not to affect both 3-year PFS and OS as well as 5-year PFS of patients with resectable cervical cancer. However, NACT significantly improves the 5-year OS of patients with resectable cervical cancer (HR = 0.83, 95% CI: 0.73-0.94, p = 0.013). Subgroup analysis (RCTs, non-RCTs, NACT + surgery + AT vs. surgery + AT, NACT + surgery + AT vs. CCRT/RT/CRT) further revealed NACT had no significant effect on 5-year PFS of patients with resectable cervical cancer, converse to the 5-year OS subgroup analysis, which validated the beneficial effect of NACT in patients with resectable cervical cancer. In addition, the effect of NACT was most significant in the non-RCTs subgroup (p = 0.012). NACT may improve the long-term prognosis of patients with resectable cervical cancer. However, further large-scale multicenter studies are needed to validate this finding.

Neoadjuvant chemotherapy plus surgery versus concurrent chemoradiotherapy in stage IB2-IIB cervical cancer: A systematic review and meta-analysis. PLoS One 2019; 14:e0225264. [PMID: 31725793 PMCID: PMC6855659 DOI: 10.1371/journal.pone.0225264] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2019] [Accepted: 10/31/2019] [Indexed: 02/07/2023] Open
Abstract
The optimal treatment strategy for stage IB2-IIB cervical cancer is controversial. This systematic review with meta-analysis evaluated the efficacy of concomitant chemoradiotherapy (CCRT) and neoadjuvant chemotherapy followed by radical surgery (NACT+S). Studies that evaluated NACT+S versus CCRT for patients with Federation of Gynecology and Obstetrics stage IB2-IIB cervical cancer were searched in MEDLINE, EMBASE, and the Cochrane Library database. Hazard ratios (HRs) with their respective 95% confidence intervals (CIs) were calculated using a random-effects model. Toxicity was also evaluated. Six qualified retrospective studies and one randomized controlled trial (2270 patients) were included in this review. The results suggested that compared with CCRT, NACT+S did not improve overall survival in all patients (HR 0.73, 95% CI 0.52-1.02) or stage IIB patients (HR 0.83, 95% CI 0.61-1.15). NACT+S did not improve disease-free survival (DFS) in stage IIB patients (HR 1.10, 95% CI 0.70-1.71). In the analysis of DFS in all patients, a high degree of heterogeneity was detected (I2 = 84%). Sensitivity analysis that eliminated these heterogeneous data suggested that CCRT could improve DFS over NACT+S (HR 1.47, 95% CI 1.12-1.93). Diarrhea and rectal and bladder complications occurred at a lower rate in the NACT+S group than in the CCRT group. NACT+S had no survival advantage for patients with stage IB2-IIB cervical cancer compared with CCRT but was associated with fewer side effects. Further prospective studies with a larger sample size of treatment protocols for locally advanced cervical cancer are needed.
