PVT1 and osteosarcoma: To investigate the correlation between lncRNA PVT1 expression and clinicopathological features of patients with osteosarcoma, 78 patients were categorized into the high lncRNA PVT1 (n = 48) and low lncRNA PVT1 (n = 30) expression groups using the average expression of lncRNA PVT1 as a cutoff value.
