Cancer treatment with tumor-infiltrating lymphocytes therapy (TIL)

TIL therapy is based on the saturation of cancer cells with the patient's lymphocytes. These are white blood cells responsible for immunity. The treatment belongs to individually designed immunotherapy to kill cancer cells. In the first stage, a part of the tissues is taken from metastases or primary tumors by biopsy. At the same time, the patient's lymphocytes are collected from the bloodstream. The doctor should receive a tumor fragment and target their immune blood cells to fight against specific cancer. The necessary lymphocytes are isolated in the laboratory. The patient can undergo other treatments during the several weeks required for growing the biomaterial. Grown cells are tested for aggressiveness to cancer if they can destroy it in a particular patient. The most aggressive cell samples continue to multiply up to 1 billion. That is the minimum required for successful treatment. In total, the cultivation stage lasts 5-6 weeks. Finally, these cells with the immunomodulator interleukin-2 are injected into the patient's body using a dropper. It takes from 30 minutes to 1. 5 hours. The body accepts killer cells since they are native biomaterial. When a changed patient's lymphocytes are inside, they travel directly to the tumor or metastases to fight and naturally destroy cancer lesions.
