**Semantic type:** Cell|Pharmacologic Substance

**Definition:** Tumor infiltrating lymphocytes (TIL) harvested directly from infiltrate of a patient's renal tumor and cultured with interleukin-2 to expand the TIL cell population. Tumor infiltrating lymphocytes have specific activity against the tumor from which they are derived. Introducing these renal tumor-reactive autologous tumor infiltrating lymphocytes back into the same patient may enhance a cytotoxic T-cell-mediated immune response against the renal cancer cells.
