Brief Communication on the Impact of β-blockers on Outcomes in Patients Receiving Cancer Immunotherapy.

Preclinical studies show that β-adrenergic activation suppresses the immune system and reduces the effectiveness of cancer immunotherapy. As a result, there is considerable interest in using β-blockers (BBs), a cheap and safe class of medication, in combination with immunotherapy to improve outcomes in cancer. This study is a systematic review and meta-analysis of clinical studies.
