According to the different ranges of primary lesions invading surrounding tissues and the different numbers of regional lymph node metastasis, it is further divided into IIIa, IIIb and IIIc. The specific severity of the disease is clinically measured by the 5-year survival rate, and after radical resection surgery with adjuvant radiotherapy and chemotherapy, the 5-year survival rate can only reach about 50%.
