Huge Advance for Cancer Treatment

This is fascinating. After 38 years in internal medicine, I've seen the practice of oncology dramatically change. When I was a new clinician, the treatment might have cured the cancer, but frequently killed the patients with toxicity. Anything to direct therapy more specifically will be a huge boost to the cancer community. As rightly pointed out, the biggest issue will be a positive liquid biopsy and no detectable disease but that should be able to be worked out with proper research. This is huge from a public health and expenditure standpoint.
