Tumour-infiltrating lymphocytes, abbreviated TILs, is the presence of many lymphoctyes between tumour cells.

TILs in the context of colorectal carcinoma are dealt with in intratumoural lymphocytic response in colorectal carcinoma.
General
Common finding in a large number of tumours:
| Tumour | Association |
|---|---|
| Colorectal carcinoma | TILs associated with microsatellite instability[1] |
| Malignant melanoma | TILs better survival[2] |
| Non-small cell lung cancer | TILs associated with anti-PD-L1 response[3] |
| Ovarian serous carcinoma | TILs associated with good prognosis[4] |
