Tumor-Infiltrating Lymphocyte (TIL) therapy harvests the patient’s own immune cells from the tumor, expands them in the lab, and reinvigorates them to fight cancer.

Response In Melanoma
Approved (Amtagvi)
Time Treatment
No. TIL therapy is currently used more commonly in certain solid tumors, especially metastatic melanoma. Patient suitability is determined on an individual basis by a specialized medical team.
Recent FDA milestones (e.g., Lifileucel) have marked a major breakthrough for advanced melanoma patients who have progressed after other treatments.
Uses the patient's own cells that have already successfully identified the tumor.
Unlike CAR-T which targets one antigen, TILs can target multiple different tumor antigens simultaneously.
Massively boosts the number of active immune cells available to fight the cancer.
Typically administered as a single treatment course rather than continuous cycles.
A surgeon removes a piece of the tumor tissue.
In the lab, TILs are isolated from the tissue and grown to billions of cells (approx. 22 days).
The patient receives a short course of chemotherapy to prepare the body for the new cells.
The TILs are infused back into the patient, followed by Interleukin-2 (IL-2) to support cell growth.
CAR T-cell therapy is an advanced immunotherapy in which a patient’s own T cells are genetically modified to better recognize and attack cancer cells, then reinfused back into the body.
It is primarily used for certain blood cancers, including specific types of leukemia and lymphoma. It is FDA-approved and shows high response rates in eligible patients.
Success varies by cancer type, but in some forms of leukemia, response rates can reach up to 90%.

No. TIL therapy is currently used more commonly in certain solid tumors, especially metastatic melanoma. Patient suitability is determined on an individual basis.
Its personalized nature and its ability to strengthen the immune system in a targeted way are considered its main advantages.
