[Function of tumor infiltrating lymphocytes in solid tumors - a review].

Abstract

Tumor is one of the major diseases threatening human health in the 21st century. Surgical resection, radiotherapy, chemotherapy and targeted therapy are the main clinical treatments for solid tumors. However, these methods are unable to eradicate tumor cells completely, and easily lead to the recurrence and progression of tumor. Tumor immunotherapy is a novel treatment that uses human immune system to control and kill tumor by enhancing or restoring anti-tumor immunity. Tumor immunotherapy has shown to produce long-lasting responses in large numbers of patients, and thereby adoptive immunotherapy and immune checkpoint inhibitors could induce remarkable antigen-specific immune responses. Tumor infiltrating lymphocytes (TILs) are highly heterogeneous lymphocytes existing in tumor tissues and play a crucial role in host antigen-specific tumor immune response. Recent studies show that TILs are closely related to the prognosis of patients during the processes of tumorigenesis and treatment. Adoptive immunotherapy mediated by TILs has displayed favorable curative effect in many solid tumors. This paper reviews the recent progress of TILs in solid tumors.
