At the same time, circPVT1 molecule can also be considered as a prognostic indicator of gastric cancer, the survival rate of gastric cancer patients with high expression of circPVT1 and low expression of PVT1 is significantly higher compared with gastric cancer patients with low expression of circPVT1 and high expression of PVT1, this joint detection of circPVT1 and PVT1 has greater application value for the prognosis evaluation of gastric cancer patients (47). The gene discussed is PVT1; the disease is gastric cancer.
