Usually, invasive 1A1 lung adenocarcinoma can undergo wedge resection, and surgical treatments such as segmentectomy and hilar mediastinal lymph node dissection are also available in this stage. Invasive 1A1 lung adenocarcinoma means that the tumor is <1cm and has not yet metastasized. Since it is in the early stage of the disease, wedge resection is usually possible, especially for patients whose imaging examination shows the presence of ground-glass nodules. Besides, patients with invasive 1A1 lung adenocarcinoma can also be considered for surgical treatments such as segmentectomy and hilar mediastinal lymph node dissection. Studies show that usually the 5-year survival rate of patients with stage IA lung adenocarcinoma is more than 80%, and the median survival period is close to 10 years. Patients with invasive 1A1 lung adenocarcinoma need to go to the hospital for timely consultation and active treatment to avoid delay.
