Abstract: Lymphocyte-led immunity plays an important role in the occurrence and development of tumors. It has been found that radiotherapy can induce lymphopenia in patients with solid tumors, and radiotherapy-induced lymphopenia (RIL) might be caused by the irradiation of circulating blood. The sensitivity to irradiation differs among different subtypes of lymphocytes. RIL can be affected by radiation fractionation, technique and volume. Meanwhile, it has been proven that RIL can significantly reduce the survival of patients with multiple solid tumors. In this article, relevant researches were reviewed, aiming to advance clinical treatment decisions and optimize radiotherapy protocols.
