Epstein-Barr virus (EBV) was the first herpesvirus associated to human malignancies. Despite the well-known association between EBV and malignancies, the prevalence of EBV infection in Malaysians with malignancies is unknown. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used to conduct a systematic review and meta- analysis of published data in this study. Studies reporting the occurrence of EBV infection in Malaysian malignancy patients were searched in electronic databases like PubMed, Scopus, ScienceDirect, and Google Scholar without year or language constraints. The study protocol was filed in PROSPERO (CRD42021273769). A total of 21 studies were included, with 1,036 EBV infection cases among 2,078 malignancy patients. The random-effects model was used to produce summary estimates. The pooled prevalence of EBV infection in Malaysians with malignancy was 36.3% (95% CI, 20.3 - 56.2). When the prevalence estimates were stratified by malignancy type, nasopharyngeal carcinoma has the highest prevalence (90.5%), followed by lymphoma (23.4%), and gastric carcinoma (10.0%). Male patients had a higher cases prevalence and most patients were above the age of 40. In Malaysia, many malignancies are increasingly linked to EBV infection. Screening for EBV infection in malignancy patients is therefore important to determine disease recurrence and metastases.
