Tumor

infiltrating lymphocytes Tumor infiltrating lymphocytes (TILs) are a type of immune cells that migrate into a tumor and play an important role in the body’s response to the cancer. TILs help the body control the growth and spread of the tumor and can act as a marker for the prognosis of the cancer. Studies have shown that the presence of TILs can be used as a predictor for a favorable outcome for some cancers, such as melanoma and ovarian cancer. Additionally, TILs can also play a role in cancer immunotherapy, where the immune cells are used to target and fight the cancer, by stimulating an immune response. TILs have the potential to be used in combination with other therapies, such as chemotherapy or radiation therapy, to improve clinical outcomes.
