Scientists uncover mutations that make cancer resistant to therapies targeting KRAS
Drugs that inhibit the protein expressed by a mutated form of the KRAS gene might soon be approved, but cancer cells often develop additional mutations that make them resist such targeted drugs. Investigators have identified some of these mutations in a patient and strategies to overcome them.

Dr. Gainor definitely deserves the name doctor. He has treated my cancer for a couple of years and since it has been gone he is doing a great job of keeping on top of the situation. I have no worries at all concerning him or the office he works in. That includes nurses and other support staff.
I am very, very happy with Dr. Gainor and the rest of the team. Everyone put my mind at ease.
Talked in layman's terms to define medical terms
Because of Dr Gainor, I'm living to play with my 4GrandChildren with my 5th one on the way. Each day is a blessing.
Dr. Gainor and the entire staff at MGH has provided excellent care for the past eight years.
I am blessed to have Dr. Gainor and his staff as part of my cancer care. Professional, caring, knowledgeable are just a few words to describe this team. I feel extremely well informed and a key part of the decision making process
Very knowledgeable and compassionate
I am just starting out with this provider but am very pleased with him. He was very professional and knowledgeable about my condition and I feel confident in him. He was also very informative and explained things in a way that I could understand not to mention the fact that he was extremely patient with my questions and spent a long time with me.
Dr Gainor is caring and very patient. Each time (2) I've come to him for a second opinion he's been kind and explained everything really well and taken all the time my family and I have needed for questions. I have already recommended 2 friends to CDH/MGB for cancer treatment and they are just as satisfied.
It was a pleasant experience visiting Dr. Gainor and his team. My great appreciations for their patience and professionalism.
