Precision medicine in immune checkpoint blockade therapy for non-small cell lung cancer
نویسندگان
چکیده
Immune checkpoint blockade therapy by targeting the programmed death protein 1/programmed death ligand 1 (PD-L1) axis using antibodies has yielded promising clinical responses in patients with non-small cell lung cancer (NSCLC). However, owing to the dynamic expression of PD-L1, degree of mutational/neoantigen load, intratumoral heterogeneity, infiltrated immune cells of tumor microenvironment of NSCLC, the response rates to these agents are limited, despite several companion diagnostic assays by detecting PD-L1 in tumor cells have been introduced into clinical practice. Therefore, in this era of precision medicine, there is an urgent need for predictive biomarkers to identify NSCLC patients likely to benefit from this novel therapy.

Background: Lung cancer is the top common cancer and cause of cancer-related death worldwide. Checkpoint blockade immunotherapies have shown extraordinarily anti-tumor effects, but only benefit the minority of patients whose tumors are pre-infiltrated by CD8+ T cells. However, the majority of solid tumors, including lung cancer are not immunogenic and CD8+ T cell infiltration is inconspicuous. ...

BACKGROUND Treatments of non-small-cell lung cancer (NSCLC)-particularly of the squamous subtype-are limited. In this article, we describe the immunomodulatory environment in NSCLC and the potential for therapeutic targeting of the immune system through cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed death-1 (PD-1) immune-checkpoint pathway blockade. MATERIALS AND METHODS We searched...

Immune checkpoint blockade (ICB), which harnesses the body's immune system to recognize and kill cancer cells, has transformed the management landscape for patients with advanced non-small cell lung cancer (NSCLC). Building on the success of this approach, clinical and translational researchers are attempting to augment the benefit of anti-programmed death 1/programmed death ligand 1 monotherap...

Modulating immune inhibitory pathways has been a major recent breakthrough in cancer treatment. Checkpoint blockade antibodies targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programed cell-death protein 1 (PD-1) have demonstrated acceptable toxicity, promising clinical responses, durable disease control, and improved survival in some patients with advanced melanoma, non-small cell lung...
متن کاملEvolution of Neoantigen Landscape during Immune Checkpoint Blockade in Non-Small Cell Lung Cancer.
Immune checkpoint inhibitors have shown significant therapeutic responses against tumors containing increased mutation-associated neoantigen load. We have examined the evolving landscape of tumor neoantigens during the emergence of acquired resistance in patients with non-small cell lung cancer after initial response to immune checkpoint blockade with anti-PD-1 or anti-PD-1/anti-CTLA-4 antibodi...
