AI Insight
This study conducted comprehensive multi-omics analysis on 112 tumor-normal tissue pairs from Chinese cervical cancer patients, revealing mutational patterns, driver genes (PIK3CA, EP300, MPRIP), and cancer-related signaling pathways. The research identified cell cycle regulation, epithelial-mesenchymal transition, and LAMC2 as potential diagnostic and therapeutic targets, and stratified patients into three distinct immune phenotypes based on their tumor microenvironments.
Why it matters
This research addresses a critical knowledge gap in understanding cervical cancer molecular profiles in Asian populations, which have been historically underrepresented in cancer genomics studies. The identified biomarkers and immune phenotypes could guide more precise diagnostic approaches and personalized immunotherapy strategies specifically for Chinese and potentially other Asian cervical cancer patients.

Genomic or transcriptomic sequencing guides the precision of cervical cancer (CC) diagnosis; however, the molecular profile of Asian patients remains poorly understood. We established a comprehensive multi-omics cohort comprising 112 tumor-normal adjacent tissue pairs from Chinese CC patients. Our integrated analysis revealed a mutational burden comparable to other populations, with three major mutational signatures primarily attributed to APOBEC-associated, age-associated, and DNA repair-associated biological categories. Multi-omics profiling elucidated the functional consequences of somatic mutations and copy number variations, identifying PIK3CA, EP300, and MPRIP as key driver events. We further uncovered both concordant and discordant activation patterns across cancer-related signaling pathways. Transcriptomic and proteomic analyses nominated cell cycle regulation, epithelial-mesenchymal transition, and LAMC2 as promising diagnostic and therapeutic targets. Comprehensive immune characterization enabled stratification of patients into three major immune phenotypes with varying microenvironmental profiles. This study provides valuable resources and novel insights into the molecular architecture of cervical cancer in the Chinese population, identifying potential biomarkers to guide precision detection and immunotherapy strategies.
