Abstract

Abstract: Background: Gestational trophoblastic neoplasia (GTN) is an infrequent spectrum of placental malignant cases. Generally, single-agent or multiple-agent chemotherapy is used to treat the condition. The condition has a significant impact on women in the childbearing age, which makes post-chemo fertility and obstetrical results a significant contemplation. Nearly 25% of GTN tumors are recurrent, or have a likelihood of relapsing after, the first round of chemotherapy. Therefore, these resistive and recurring lesions require salvage chemotherapy with or without surgical treatment. Therefore, the current meta-analysis and systematic review will assess the effectiveness and level of safety when using chemotherapy to treat women with resistive or recurring GTN. Methods: The current study will perform a comprehensive systematic search for randomized controlled trials (RCTs) that have assessed the efficacy and safeness of chemo as a line of treatment for women with resistive or recurring GTN. To this end, a search will be conducted on the following electronic databases: Web of Science, MEDLINE, Chinese National Knowledge Infrastructure (CNKI), EMBASE, WanFang database, and the Cochrane Library. The search will cover the period from the inception of databases to May 2021. In order to identify additional related studies, we will manually search the reference lists of suitable research articles and related systematic reviews. A pair of independent authors will review the titles/abstracts of the studies to check if the studies are eligible, which is proceeded by screening the full texts. This study will employ a uniform data extraction table for data extraction. Moreover, based on the Cochrane Risk of Bias Tool, this protocol review also assesses the bias risk in the studies involved. Results: A comprehensive synthesis of existing indication on chemo treatment for women with resistive or recurring GTN. Conclusion: The results offer fresh references for evaluating the effectiveness and safeness of chemo-based treatment for women with resistive or recurring GTN. Ethics and dissemination: An ethical approval is not needed as all data are published. Review registration number: May 17, 2021.osf.io/uwky7. (https://osf.io/uwky7/ ).
