Scientists can isolate these T cells from surgically removed tumor samples, manipulate the cells in the lab — including growing large numbers of them — and reinfuse them into the patient.
Most of the work in this area has focused on melanoma, but TIL therapies are also being developed for other cancers, such as lung and bladder cancer. Engineered T cells come in two major types: Engineered TCRs are enhanced versions of the natural receptor molecules T cells use to recognize and respond to targets on other cells. CARs combine part of the T-cell receptor with part of another immune system component called an antibody. Each type of engineered T cell has its own advantages.
To date the most promising results have been in patients with certain leukemias and lymphomas e. Antibody-based treatments use highly selective immune system proteins called antibodies either alone or attached to chemotherapy or radioactive particles the latter is called radioimmunotherapy to directly destroy cancer cells, sparing healthy cells and thus minimizing harmful side effects.
David Maloney was instrumental in the development of rituximab, the first antibody-based cancer treatment approved by the FDA. Oliver Press pioneered radioimmunotherapy for patients with blood cancers. The immune system has built in mechanisms called checkpoints to keep itself under control — to prevent it from reacting to normal cells autoimmunity or to switch off a legitimate reaction before it becomes too vigorous.
Cancer cells often hijack these sophisticated control mechanisms to avoid being attacked by the immune system. Recent success with these agents in some patients with melanoma and lung, kidney, ovarian and bladder cancer is exciting because it indicates that these more common solid tumors are susceptible to immune attack.
The challenge is that not all patients respond to the checkpoint inhibitors, and these agents are non-specific: They affect the entire immune system and so can cause severe side effects in some patients.
I was diagnosed with stage 4 melanoma in late September I started Immunotherapy involving nivolumab and ipilimumab. After two immunotherapy sessions the previously seen multiple tiny nodular enhancing lesions throughout the cerebral hemispheres have either decreased in size or resolved, with 3 residual enhancing lesions in the left frontal and temporal lobes, reflecting interval therapy.
