Currently, the clinical practice does not use cure rate to describe the prognosis of lung cancer, but 5-year survival rate is used instead.The 5-year survival rate of stage 1B squamous lung cancer is about 70%. Lung squamous carcinoma is a pathological type of lung cancer, which belongs to a kind of non-small cell carcinoma of the lung and is slightly less malignant than small cell carcinoma. And stage 1B is a stage of TNM staging, i.e., T2a, N0, M0, which refers to the tumor with maximum direct greater than 3cm, less than or equal to 4cm, the tumor without lymph node metastasis, and no distant metastasis of the tumor. Lung cancer patients may still have postoperative recurrence, secondary recurrence or metastasis even if they receive complete resection of the tumor, so lung cancer cannot be statistically and descriptively prognosticated by the cure rate. According to statistics, the five-year survival rate of stage IB non-small cell carcinoma is about 70%, and that of stage IA is about 80%, and the later the stage, the lower the survival rate. Although the five-year survival rate of stage IB squamous lung cancer is 70%, as long as the treatment is reasonably standardized and the risk factors of lung cancer are changed, the survival rate will be greatly improved.
