Who is the father of Immunotherapy?
However, the modern science of immunology has shown that Coley’s principles were correct and that some cancers are sensitive to an enhanced immune system. Because research is very active in this field, William B. Coley, a bone sarcoma surgeon, deserves the title “Father of Immunotherapy”.
Does Immunotherapy work for all cancers?
Each type of cancer is unique. Immunotherapy doesn’t work for all types of cancer or for all people with cancer. But doctors continue to test new treatments. Some types of immunotherapy have become a standard part of treatment for certain types of cancer.

What happens when you finish immunotherapy?
When a tumor responds to immunotherapy, the remission tends to last a long time (a year or more), unlike a response to chemotherapy (weeks or months). Also, with immunotherapy, tumors initially may swell as immune cells engage with the cancer cells, then later shrink as cancer cells die.
How much time does Keytruda prolong life?
The average overall survival duration among Keytruda treated patients is now 26.3 months compared to 14.2 months for those treated with chemotherapy. The 36-month overall survival is 43.7% for Keytruda compared to 24.9% for chemotherapy.
Can you take Keytruda longer than 2 years?
Survival was particularly pronounced for the 60 individuals in the study who had received Keytruda treatment for two years or more, with 45 alive at five years. Notably, researchers found late-onset toxicity from treatment was rare, with rates of immune-mediated adverse events roughly similar at three and five years.
Does Keytruda extend life?
In the KEYNOTE-010 trial, treatment with Keytruda significantly improved overall survival (the period of time patients on a trial are still alive after they are diagnosed or started treatment) and progression-free survival (the time from treatment to disease progression or worsening).
