Most patients with 1a2 infiltrating lung cancer can survive for 10 years if actively treated. The specific survival time is mainly related to factors such as disease progression, treatment sensitivity, and individual physique. 1a2 infiltrating lung cancer belongs to early stage lung cancer, and radical surgical resection is generally preferred. The 5-year survival rate of non-small cell lung cancer in postoperative stage IA is about 73%, so patients without recurrence after surgery can survive for 10 years, or even get long-term survival. However, the specific survival time is also related to the progress of disease, sensitivity of treatment, and individual physique. 1. Disease progression: do a good job of regular follow-up after surgery, if the disease does not recur after surgery, the general prognosis is better, and long-term survival can be obtained. If the recurrence of metastasis involves more foci, the prognosis is poorer. 2. Therapeutic sensitivity: For patients with recurrent metastasis, targeted therapy can be performed. The higher the sensitivity of tumor cells to targeted therapeutic drugs, the better the therapeutic effect, the more conducive to relieving symptoms and improving quality of life, and the better the survival rate. On the contrary, the prognosis is poor. 3. Physical fitness: the better the physical fitness of the individual and the healthier the lifestyle, the better the survival rate will be. On the contrary, the prognosis is poorer. In addition to the above factors, the survival rate of the disease is also related to compliance with medical treatment and a positive and optimistic attitude. It is recommended that after diagnosis, early and regular treatment should be carried out in order to obtain a good prognosis.
