CLINICAL CONSIDERATIONS
Patients may respond differently to immunotherapy than to traditional cancer agents.
-
Immunotherapy targets the tumor over time, so although response may occur more slowly than with traditional cytotoxic therapies, the immune effect is potentially adaptable and durable2-4
-
RECIST criteria were designed to assess response to traditional cytotoxic agents so they are not as relevant for immunotherapy, which works differently2-4
