According to statistics, there were 4,292,000 new cases of tumors and 2,814,000 deaths in 2015. Lung cancer is the most prevalent tumor and the leading cause of cancer death. Surgical resection is the best way to treat lung cancer, so what are the conditions under which lung cancer has a chance to be operated? (Remark: The following is only for those who are in good health) First: patients diagnosed with non-small cell lung cancer, including adenocarcinoma, squamous carcinoma, large cell carcinoma, alveolar carcinoma, adenosquamous carcinoma, etc., with stage I, stage II, some stage IIIa (T1-2N1-2M0, T3N1-2M0, T4N0M0 that can be completely resected), including stage N2 patients with effective neoadjuvant chemotherapy; a small number of stage IIIb patients who can be completely and locally resected by surgery; a few Stage IV only have single lung metastasis, single brain metastasis, and single adrenal metastasis. The second type: only stage I patients who are diagnosed with small cell lung cancer may choose surgery; the third type: when the nodules in the lungs are determined by experts to be highly suspicious of malignancy and cannot be diagnosed qualitatively by various examination means, surgical exploration and removal of the lung nodules may be considered for qualitative diagnosis with the consent of the patient and family members. Generally speaking, qualified oncology institutions will tell the patient the exact pathological tissue type of lung cancer and the exact stage of the disease (which stage is I, II, III, IV) as far as possible, and then determine whether surgery is feasible by taking into account the patient’s age and basic physical condition. Most stage I (early stage) patients can be cured by surgery, while stage 2-3 patients need to consider the outcome of surgery and long-term benefits.
