title: [Surgery for non-small cell lung cancer based on the T factor].
abstract: We review the indications of surgery in patients with non-small cell lung cancer (NSCLC) based on the T factor, focusing on peripheral small tumors, invasion to other organs, and the presence of malignant pleural effusion or intrapulmonary metastasis. While limited surgery in patients with peripheral, small-sized NSCLC preserves postoperative pulmonary function, the prospects for long-term survival are reduced due to the likelihood of recurrence, Novel prospective studies are being conducted to determine the indications for limited surgery in such patients which focus on histology, tumor size, and pulmonary function. In some patients with locally advanced disease, especially with invasion of the chest wall (T3), pericardium (T3), left atrium (T4), great vessel (T4), and carina (T4) and with malignant pleural effusion found intraoperatively and ipsilateral intrapulmonary metastasis, complete resection results in long-term survival. Thus surgery should be considered in patients without N2 disease.
