Oral cancer in women: a silent epidemic? Indian scientists have made a groundbreaking discovery that could revolutionize how we understand and treat oral cancer in women. This research, conducted by a team from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, and the BRIC-National Institute of Biomedical Genomics (NIBMG), Kalyani, in collaboration with clinicians from Sri Devraj Urs Academy of Higher Education and Research (SDUAHER), Kolar, sheds light on the unique genetic factors driving this devastating disease.
The study, which focused on women in southern India, specifically those with a unique tobacco-chewing habit, aimed to understand the distinct characteristics of oral cancer in women. This is crucial because, while oral cancer is widely studied in men, the female experience has often been overlooked.
But here's where it gets interesting: The team utilized artificial intelligence (AI) to analyze tumor tissues digitally. This revealed two distinct groups of female patients, each exhibiting a different immune response within their tumors. This could lead to more personalized and effective treatment strategies.
Why is this so important? India faces one of the world's highest burdens of oral cancer, with alarmingly high rates among women in certain regions, particularly in southern and northeastern India. This is largely due to the widespread habit of chewing tobacco-infused betel quid, gutka, and similar products.
The researchers analyzed tumor and blood samples from female patients with a specific regional tobacco-chewing habit (Kaddipudi), common in the Kolar district of Karnataka. Their analysis revealed a unique driver mutation implicated in oral tumorigenesis. This finding, published in the Clinical and Translational Medicine Journal, is a significant step forward in understanding the aggressive nature of oral cancer in Indian women.
And this is the part most people miss: Using advanced whole-exome sequencing, the team identified ten key genes with significant mutations in the female cohort. While the genes CASP8 and TP53 were highly mutated, CASP8 emerged as the unique driver mutation, unlike previous studies primarily focused on male patients. The findings suggest that the combination of TP53 and CASP8 mutations leads to a more aggressive and life-threatening form of oral cancer.
The team is now focused on understanding the molecular mechanisms behind this novel driver mutation, which could pave the way for targeted therapies.
