Editorial comments for the circular RNA circPRKCI promotion of tumor growth in lung adenocarcinoma
Lung cancer is one of the leading cause of death worldwide (1). There are two major forms of lung cancer: non-small cell lung cancer (NSCLC) (about 85%) and small cell lung cancer (SCLC) (about 15%). Treatments for lung cancer are mainly surgical resection, chemotherapy and targeted therapy, however, these treatments rarely achieve a cure, and the 5-year survival rate is still low (2). Therefore, there is an urgent need for new diagnostic biomarkers to ensure that lung cancer patients can be treated in an effective manner and survive longer.
