Taimur Khalid (Medicine) tied for first place for Best Case Presentation Poster at the Clark County Medical Society Symposium on February 1 for his research on liquid biopsy in head and neck cancer, an innovative diagnostic approach that could revolutionize cancer treatment. Alongside co-author Dr. Jo-Lawrence Martinez Bigcas Assistant Professor and Residency Program Director of the Department of Otolaryngology – Head and Neck Surgery at the Kirk Kerkorian School of Medicine at UNLV,from the Kirk Kerkorian School of Medicine at UNLV, Khalid explored how circulating tumor DNA (ctDNA)—fragments of tumor DNA found in the bloodstream—can provide real-time insights into cancer progression and treatment decisions. The study focused on a 42-year-old patient with HPV-positive tonsillar cancer, whose ctDNA levels were used to justify the decision to forgo standard radiation and chemotherapy. Remarkably, the patient’s ctDNA remains undetectable two years post-surgery, suggesting no residual disease. This case raises important ethical and medical questions about balancing emerging technologies with established treatment guidelines and respecting patient autonomy. Khalid’s research underscores the potential of ctDNA as a non-invasive biomarker for monitoring cancer, offering a glimpse into a future of precision medicine where treatment is tailored to each patient’s unique biology. His award-winning work highlights the intersection of technology, ethics, and patient-centered care, contributing to the evolution of oncology practices.
