Segmentectomy: The lungs are divided into multiple lobes. A segmentectomy involves the removal of part of one of the lobes of the lung to entirely remove a cancerous tumor. segmentectomy can preserve more normal functional lung tissues.
Study summary
This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1025. The goal of this clinical trial is to confirm the theraputic effect of segmentectomy for solid-dominant invasive lung cancer with size of 2-3cm. The main questions it aims to answer are:
* The 5-year disease-free survival of patients having solid-dominant invasive lung cancer with size of 2-3cm;
* The post-operative lung function tests after receiving segmentectomy. Participants will receive segmentectomy as the surgical procedure.
