Somatic Variations in Cervical Cancers in Indian Patients

Area of Science:

• Oncology
• Genomics
• Molecular Biology

Background:

• Cervical cancer is a leading cancer among Indian women.
• Limited data exists on the mutational landscape of cervical cancer in this population.
• Understanding somatic mutations is crucial for targeted therapies.

Purpose of the Study:

• To investigate the spectrum of somatic mutations in cervical cancer.
• To identify novel mutations and frequently altered pathways in Indian patients.
• To establish a genomic profile for cervical cancer in India.

Main Methods:

• Whole exome sequencing (WES) was performed on 10 treatment-naïve tumor biopsies and matched blood samples.
• Somatic mutations were identified and compared against the COSMIC database.
• Pathway enrichment analysis was conducted to identify frequently mutated pathways.

Main Results:

• 1831 genes harbored somatic mutations, with 1282 exhibiting missense mutations.
• 272 previously reported mutations (in other cancers) were identified in 250 genes.
• Over 1000 novel somatic variations were discovered in the Indian cohort.
• Significant enrichment of somatic mutations was observed in the MAPK signaling pathway.

Conclusions:

• This study provides the first WES data for well-annotated cervical cancer samples from Indian women.
• Identified mutation profiles and frequently mutated pathways, including MAPK, offer potential therapeutic targets.
• Findings highlight unique mutational trends in an Indian cervical cancer cohort, informing future research and treatment strategies.
