Introduction Early diagnosis and treatment of human immunodeficiency virus (HIV) can improve outcomes. HIV prevalence in brain tumor patients and the impact of an HIV diagnosis on patient outcomes are poorly understood. Materials and methods This was a prospective study of 100 consecutive brain tumor patients admitted to a Greater London Tertiary Neurosurgical center for surgery between January 2021 and October 2021. All brain tumors were included. All patients have appropriately consented. Blood was tested to detect HIV antibodies and p24 antigen. Outcomes were noted at 30-day postoperative follow-up. Results In 100 patients, there was one case of a known HIV-positive, seronegative patient, and no new diagnosis was made, giving a prevalence of 1%. The mean age of patients included was 61.7 ± 13.3, with 57% female. The patient with HIV suffered a postoperative pseudomonas infection, requiring intensive care, additional surgery, and antibiotics. This resulted in an inpatient stay of 55 days - an increase of 274% compared to patients without HIV. Conclusion Literature regarding the prevalence of HIV in glioma patients is inconclusive, of low quality, and primarily out-of-date. Our literature search found no similar study of rates of HIV in brain tumor patients in the United Kingdom. The incidence of both HIV and brain tumors, particularly glioblastomas, is low.
