Case-control study of PD-1, PD-L1 and B7-H3 expression in lung cancer patients with and without human immunodeficiency virus (HIV) infection

HIV-infected lung cancer patients had significantly higher B7-H3 tumor expression compared to HIV-uninfected controls, with similar rates of tumor PD-L1 expression, as well as PD-1 and PD-L1 expression on TII. These results support inclusion of HIV-infected lung cancer patients in future immunotherapy trials.
