New therapeutic approaches in the treatment of node-positive cervical cancer patients based on molecular targets: a systematic review.

Abstract

Cervical uterine cancer is the second most frequent female cancer worldwide and a substantial burden for low-income societies and the patients themselves. Understanding the molecular mechanisms of metastasis permits the development of therapies that limit tumor progression, as well as providing health and social benefits. Pathomorphology is still the basis of research and a reference standard for molecular analysis. The aim of our study was to research and critically evaluate clinical trials that use new oncological approaches for node-positive cervical cancer to gain an insight into the molecular mechanisms of tumor metastasis.\n\n\nINCLUSION CRITERIA\nnode-positive disease at baseline; at least a first phase clinical study comprising adult female patients; novel clinical approach (e.g., radiotherapy, immunotherapy, targeted therapy, vaccines, radiosurgery); histologic measurement of treatment efficacy (preferably lymph node ultrastaging); and publications in English language only.\n\n\nINFORMATION SOURCES\nUS Clinical trials registry, EU Clinical trials register, ISRCTN registry, and Ovid, EBSCO and Cochrane Collaboration databases. Access dates: from January 2010 to April 2018.\n\n\nEXCLUSIONS\nAbstracts that did not meet the inclusion criteria or with unreliable data. We collected complete data (e.g., the entire publication associated with included abstracts, heterogeneity examination of individual studies, and validity measurement of the statistical methods used). Results were analyzed in relation to the most recent understanding of the pathogenesis of cervical cancer metastasis. We proposed a possible direction for drug treatment of epithelial tumors based on the mechanisms of metastasis.
