Hypofractionated lung adenocarcinoma IB belongs to the early stage of the disease and has a better prognosis than the late stage, but due to individual differences, the specific prognosis cannot be generalized. However, poorly differentiated lung adenocarcinoma refers to poorly differentiated lung adenocarcinoma, usually the lower the differentiation, the higher the degree of malignancy, and prone to lymph node metastasis and distant metastasis. However, as stage IB is relatively early, patients can have their lung lobes or lung segments resected by surgery to achieve relatively better treatment effect, and after surgery, radiotherapy and chemotherapy can improve the prognosis and reduce the risk of recurrence and metastasis according to the condition. Patients should develop good living habits in daily life, pay attention to rest, moderate exercise, balanced diet, eat more high-quality protein, fresh fruits and vegetables, and coarse grains.
