A number of studies revealed that the high expression of PVT1 is closely related to the survival of patients suffering from breast cancer, but the results are also quite different.[16,17] In order to more accurately analyze the impact of high expression of PVT1 on the survival of patients with breast cancer, this study comprehensively searched literatures that are related to the expression of PVT1 and the prognosis of patients with breast cancer, and adopted meta-analysis to evaluate the effects of high expression of PVT1 on the prognosis of patients with breast cancer. This evidence concerns the gene PVT1 and breast carcinoma.
