Abstract
Epithelial ovarian cancer, primarily high-grade serous ovarian cancer, is a tumor characterized by a high probability of recurrence following primary treatment, which consists of cytoreductive surgery combined with platinum-based chemotherapy. Despite standardized therapeutic approaches, the platinum-free interval, progression-free survival, and overall survival vary substantially. Beyond somatic tumor characteristics and the completeness of cytoreduction, a significant portion of this variability may be driven by germline single-nucleotide polymorphisms (SNPs) in genes encoding proteins responsible for drug transport, detoxification, and DNA repair. The objective of this review is to systematize data on the molecular mechanisms of platinum sensitivity and resistance in serous ovarian cancer, with an emphasis on the role of germline structural DNA variants (SNPs), discuss the limitations of existing data, and outline directions for future research.
A literature search was performed in PubMed, Scopus and Google Scholar using the following keywords: “high-grade serous ovarian cancer”, “platinum”, “carboplatin”, “cisplatin”, “polymorphism”, “SNP”, “pharmacogenetics”, “progression-free survival”, and “platinum resistance”. Priority was given to studies with a sample size of ≥100 ovarian cancer patients and those with independent validation or a meta-analysis. A number of studies with smaller sample sizes were included due to the particular significance of their results and are specified in the text. The most reproducible associations with platinum resistance are demonstrated by SNPs in genes involved in nucleotide excision repair pathways (ERCC1, ERCC5), platinum transport and excretion (ABCB1), and specific signaling pathways (STAT3, FGFR4). Many candidate associations remain controversial owing to variations in the definition of platinum resistance, small sample sizes, heterogeneity in treatment regimens, and interethnic differences in allele frequencies and effects.
