My mother, age 67, was diagnosed with mucosal melanoma in late February, primary in the rectum and mets to the liver. She began experimental treatment with AZD6244 at Mt. Sinai Miami Beach under Dr. Jose Lutzky. She tolerated it well but it was determined that it was not doing anything and the disease was progressing. She went to Memorial Sloan Kettering in NYC and was put on Gleevec in late June. Unfortunately, she passed away on July 10th.
Your doctor, Dr. Hodi, is also well known in this field.
Good luck to you.
