mutation. His cell type is Non Small Cell Lung Cancer. Although they removed his lung and he did have conventional chemotherapy (he had a port too), after chemo he participated in a trial with a drug erlotinib that targets the EGFR mutation. Unfortunately he developed liver toxicity and had to stop. Fortunately the liver issue resolved, so the standard of care is just observation. They hope the chemotherapy worked. I knew that was bullshit, because in the 80's when I worked in Cancer research, chemo did not work that well. Lung cancer is TOUGH. It doesn't just kill the cancer cells but all proliferating cells. The thinking is the dividing cells are more vulnerable, but it is not a targeted solution. Bill's cancer spread to his brain and adrenal in that time of observation, within 6 months. He underwent the gamma knife for the brain mets. They had a new targeted 3rd generation, Tyrosine Kinase Inhibitor (TKIs). The new drugs target the cause of the cancer cell growth. Sadly over time the cells mutate again and the cancer spreads. I pray that they will have found another successful drug by then. He takes one pill ($500) every day. He has been 2 years no evidence of disease (NED) Dear Lord let this work forever please.
