Progress of biological mechanism of immune checkpoint inhibitors and their applications in treatment of lymphoma / 白血病·淋巴瘤

ABSTRACT

Malignant lymphoma is a common malignant tumor of the lymphatic system. In recent years, immunotherapy is a new direction in the field of lymphoma treatment after targeted therapy, radiotherapy and chemotherapy. Immune checkpoint inhibitors (ICPi) have achieved significant efficacy in Hodgkin lymphoma (HL), with an overall response rate of about 80%, which makes the clinical application of ICPi in patients with malignant lymphoma become the focus of attention. This article reviews the recent progress in the biological mechanism of programmed cell death 1 (PD-1) and cytotoxic T lymphocyte-associated antigen (CTLA-4), and the application of ICPi in the treatment of HL and non-Hodgkin lymphoma.
