Stage ⅠB lung cancer refers to clinical staging of T2aN0M0, which is early stage lung cancer.
Lung cancer can be divided into four stages by adopting TNM staging method: Stage IA, Stage IB, Stage IIA, Stage IIB, Stage IIIA, Stage IIIB and Stage IIIC, Stage IVA, Stage IVB.
Stage IB lung cancer refers to clinical stage T2aN0M0, which is defined as a tumor with a maximum diameter of 3~4cm, without regional lymph node metastasis and distant metastasis.
Early stage lung cancer may not have any clinical symptoms, or only be found during routine physical examination, or there may be irritating dry cough accompanied by little sputum, which leads to worsening of cough, chest pain, and even symptoms such as blood in sputum, hemoptysis, hoarseness and dyspnea.
If the patient’s general condition is still good, surgical treatment should be preferred, and stage 1B lung cancer can be eradicated by surgery, and the surgical effect is better. stage 1B lung cancer needs 4 cycles of adjuvant chemotherapy after surgery, which can prevent local recurrence and metastasis to other parts of the body.
If the patient has no recurrence for more than 5 years, basically it is cured, and the survival rate of 5-year patients reaches more than 60%, but it is also necessary to have regular checkups and close follow-ups.
