Survival of patients with squamous lung cancer after surgery varies from person to person and is related to the patient’s postoperative pathological stage, molecular markers, coexisting disease, and care. Based on the pathological stage of the tumor, the 5-year survival rates for patients with lung squamous carcinoma are 73%, 58%, 46% and 36% for stage IA, IB, IIA and IIB, respectively. In case of early stage lung squamous carcinoma, such as stage I lung squamous carcinoma, the tumor spreads less and can be removed by radical surgery, the 5-year survival rate is higher, and even some patients can survive for a long time. For patients with stage II squamous lung cancer, the tumor spreads to a larger extent and may have a relatively higher chance of tumor recurrence, and the 5-year survival rate will be relatively lower. In addition, patients with molecular markers have a better prognosis, for example, patients with EGFR mutations have a relatively better prognosis. In addition to clinical staging and molecular markers, patient survival is also related to general status and underlying disease. Patients with good general status and few underlying diseases will have a relatively longer survival. In addition, postoperative care is also important. Patients with lung squamous carcinoma should develop good living habits, eat regularly, eat more food rich in high quality protein, as well as fresh fruits and vegetables, supplement protein and vitamins, avoid overeating, quit smoking and alcohol, conduct regular review, and seek medical treatment in time for any discomfort in daily life. As mentioned above, if patients with squamous lung cancer are operated in time at the early stage of the disease, the possibility of sequelae can be reduced, the 5-year survival rate of patients can be increased, the survival cycle can be prolonged and the quality of life can be improved.
