摘要

Epithelial ovarian cancer (EOC) remains the most lethal gynaecological malignancy in developed countries, with recurrence and drug resistance posing significant clinical challenges. Brain metastases (BM) from epithelial ovarian cancer, once rare, are an increasing phenomenon and are characterised by a dismal prognosis. To explore the molecular underpinnings of BM in EOC, we conducted a multimodal genomics and transcriptomics analysis of matched primary tumour and brain metastases samples from a retrospective cohort. Our findings revealed high genomic concordance between primary tumour (PT) and BM, with alterations in key pathways such as MYC (MYC Proto-Oncogene, bHLH Transcription Factor) targets, extracellular matrix remodelling, and inflammatory signalling characterizing the BM. AFP (Alpha-fetoprotein) and GFAP (Glial Fibrillary Acidic Protein) emerged as potential biomarkers from the primary lesion for BM onset, while network analysis identified MET (MET Proto-Oncogene, Receptor Tyrosine Kinase), GDF15 (Growth Differentiation Factor 15), and S100A9 (S100 Calcium Binding Protein A9) as candidate mediators of tumour-brain crosstalk. These results offer new insights into EOC brain tropism, highlighting potential targets for therapeutic intervention and personalized patient management in the precision oncology era.
