Recent studies have shown that miR‐802 is abnormally expressed in many tumors. miR‐802 is expressed at low levels in tissues and cells of gastric cancer, colorectal cancer, breast cancer, cervical cancer, epithelial ovarian cancer, tongue squamous cell carcinoma, oral squamous cell carcinoma, esophageal squamous cell carcinoma, laryngeal squamous cell carcinoma, and melanoma. In contrast, miR‐802 is overexpressed in hepatocellular carcinoma, bladder urothelial cancer, osteosarcoma, and cholesteatoma tissue cells. It should be noted that the results of studies on the expression of miR‐802 in pancreatic cancer, prostate cancer, and lung cancer are inconsistent. Current studies have found that miR‐802 can target and regulate genes in different tumors, and affect the regulation of the Wnt signaling pathway, EMT signaling pathway, PI3K/AKT signaling pathway, ERK signaling pathway, and Hedgehog signaling pathway. At the same time, miR‐802 is regulated by the endogenous competition of four ceRNAs, including circDONSON, IGFL2‐AS1, MIR155HG, and MIR4435‐2HG. This article reviews the abnormal expression of miR‐802 in a variety of tumors, expounds the mechanism by which miR‐802 affects tumor progression by regulating different target genes, and elaborates the network of miR‐802‐related ceRNAs. We also summarized the limitations of miR‐802 research and looked forward to the potential application of miR‐802 in the diagnosis and prognosis of tumors.
