Dr. Kanetsky has made seminal contributions to our understanding of melanoma and testicular germ cell tumors. Melanoma is a potentially lethal form of skin cancer and is the sixth most diagnosed cancer in Floridians. The high level of sun exposure, the most important environmental risk factor for melanoma, in the Sunshine State is partially responsible for the escalating occurrence of melanoma, especially among young adults. Increasing prevention behaviors such as responsible sun seeking and skin examinations can help ebb the rising tide of melanoma diagnoses, and Dr. Kanetsky’s research seeks to determine whether knowledge of genetics can affect melanoma risk behaviors. Testicular germ cell cancers are the most common cancer in men between the ages of 15 and 35. Although highly treatable, standard chemotherapies have unpleasant and sometimes severe adverse consequences that can lead to decreased quality of life among these young men. Dr. Kanetsky plays a leadership role in an international genetic research consortium that addresses a spectrum of scientific questions focused on testicular germ cell tumors to better serve this adolescent and young adult male population. Dr. Kanetsky’s research projects encompass the investigation of (i) inherited genetic factors and sun exposure on risk of melanoma and melanoma-related traits, (ii) influence of genes on survival outcomes among melanoma patients treated with immunotherapy, (iii) whether knowledge of genetic susceptibility affects positive change in melanoma risk reduction behaviors, and (iv) inherited genetics and risk of testicular germ cell tumors, tumor-related phenotypes, and survival outcomes.
