Cancer researchers claim 'extraordinary results' using T-cell therapy
Source: Guardian
Scientists are claiming “extraordinary” success with engineering immune cells to target a specific type of blood cancer in their first clinical trials.
Among several dozen patients who would typically have only had months to live, early experimental trials that used the immune system’s T-cells to target cancers had “extraordinary results”.
In one study, 94% of participants with acute lymphoblastic leukaemia (ALL) saw symptoms vanish completely. Patients with other blood cancers had response rates greater than 80%, and more than half experienced complete remission.
Speaking at the annual meeting for the American Association for the Advancement for Science (AAAS), researcher Stanley Riddell said: “This is unprecedented in medicine, to be honest, to get response rates in this range in these very advanced patients.”

Best wishes for your dad. 
I have no idea whether this program would be interesting or useful to you, but a teacher at my daughter's school is enrolled and he got access to the same medication that Jimmy Carter was given when he was diagnosed with cancer (which is as far as I know still in remission). Not that your dad would necessarily get the same medication, but it might open up some possibilities?

My dad is doing ok considering.
The treatments have thus far minimized the tumor growth and his quality of life is pretty good considering his age.
Thanks for the best wishes!
