#62 - Keith Flaherty, M.D.: Deep dive into cancer—History of oncology, novel approaches to treatment, and the exciting and hopeful future

In this episode, Keith Flaherty, director of clinical research and targeted cancer therapy at Massachusetts General Hospital, shares his vast wealth of knowledge in cancer starting with the history of treatment from chemotherapy to radiation to surgical therapy and where those methodologies seemed to have leveled off. He also walks us through the timeline of advancements (and lack there of) from when the War on Cancer was declared in the 1970s, through the sequencing of the entire human genome, and all the way to today. Keith dives into the topic of immunotherapy, probably the most exciting recent development in cancer therapy, and also provides us a rundown of his notion of a different approach to cancer that attacks all the essential pillars of cancer growth and survival. Finally, we talk a little bit about liquid biopsies, we discuss the roles of CRISPR and other potentially over-hyped therapies with respect to cancer. We also touch on stem cell therapy a bit, as well as some other common cancer-related questions such as the role of vitamin D and sun exposure in melanoma, and much more. We discuss: Growing up around medicine, and finding a career that you love [7:30]; Medicine as a career, limitations of the med school teaching approach, and the dynamic and accelerating field of medicine and technology [16:30]; Explaining chemotherapy, radiation, and how a cancer develops [23:45]; Surgical oncology, cure rate of solid tumors, and survival rate after tumor removal  [33:15]; 25 years after the War on Cancer is declared, gene sequencing, and why Keith's was fascinated by the HIV case study [37:15]; Cancer immunotherapy: History, how it works, and why some cancers respond and others don't [46:00]; MHC complexes, and cancer cloaking mechanisms [56:00]; Comparative biology of cancer: Why some cancer can evade immune detection better than others [1:03:00]; What we learned from the Cancer Genome Atlas Project [1:07:00]; Defining targeted therapy, HER2 breast cancer, ch
