Effect of the combination of trastuzumab, paclitaxel and carboplatin in the treatment of uterine serous carcinoma: A systematic review and meta-analysis

Abstract

Purpose: To systematically review the efficacy of paclitaxel-carboplatin versus trastuzumab in combination with paclitaxel/carboplatin for the treatment of uterine serous carcinoma (USC) with high Her2/neu expression, in order to obtain an evidence-based reference for clinical treatment.Methods: Publications were obtained from China Knowledge Network (CNKI), VIP database (VIP), Wanfang database, PubMed, Embase, Cochrane Library, and Web of Science. The retrieval period was from the establishment of database to May 2022, and the efficacy of paclitaxel-carboplatin combination with trastuzumab (study group) versus paclitaxel-carboplatin (control group) for the treatment of Her2/neu high-expressing USC was collected. Two reviewers independently screened, extracted data, and evaluated the quality of evidence of included studies. RevMan 5.3 statistical software was used for meta-analysis. Outcomes included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events.Results: Meta-analysis showed that the study group had significantly longer OS than control group (p = 0.004), and PFS of study group was significantly longer than that of control group (p < 0.0001). In terms of ORR, there was no difference between the two groups (p = 0.42). However, in terms of total and high-risk adverse events, the number of patients with adverse events in study group was higher than in control group (p = 0.05), (p = 0.0001).Conclusion: Paclitaxel-carboplatin combination with trastuzumab significantly prolongs OS and PFS in USC patients with high Her2/neu expression, but it may increase the incidence of adverse events.
