There is no specific number of years of survival for patients with microinfiltrating lung adenocarcinoma. It needs to be analyzed based on specific factors such as the patient’s physical condition and the outcome of treatment. Microinvasive lung adenocarcinoma is a subtype of lung adenocarcinoma and patients are mainly considered for radical surgical treatment to remove the cancerous lesions, and patients generally have a higher 10-year survival rate. Some microinvasive lung adenocarcinoma may also have distant metastasis. If distant metastasis occurs, chemotherapy, radiotherapy, targeted therapy, immunotherapy, etc. should be administered according to the situation, and patients’ survival time is usually 1-2 years, and even only 3 months for those with severe disease. Once the diagnosis of microinvasive lung adenocarcinoma is confirmed, patients should actively cooperate with the treatment, early detection and timely treatment, the prognosis is usually better, and the survival time of patients will be relatively longer.
