David Bhatt

David Bhatt has contributed to advancing sentinel lymph node biopsy techniques across multiple cancer types as a minimally invasive alternative to complete lymph node dissection for staging purposes. His research has examined sentinel node mapping accuracy using radiolabeled colloid and blue dye techniques in melanoma, breast cancer, and vulvar cancer, characterizing false-negative rates and technical factors that influence mapping success. He has investigated outcomes in patients managed with sentinel node biopsy alone versus completion lymph node dissection, contributing to evidence that has reduced the need for extensive nodal surgery in most sentinel node-positive patients. His work spans surgical technique refinement, nuclear medicine collaboration, and long-term oncologic outcome analysis for sentinel node biopsy across cancer types.
