Segmentectomy of early stage lung cancer: From technology to clinical research / 中国胸心血管外科临床杂志

ABSTRACT

@#Segmentectomy is the removal of certain segments of the lung with lesions and retaining the normal lung tissue of the lobe. Lung segmentectomy is considered difficult due to the lack of clear anatomical boundaries between lung segments. Segmentectomy has a variety of indications, such as lung cancer, metastatic lung tumors, and many non-malignant diseases. In the treatment of early stage lung cancer, segmentectomy was initially considered only as a treatment option for patients not suitable for conventional lobectomy. As more evidence emerged, the indications for segmentectomy have continued to change over time, and segmentectomy has been widely performed in patients with early stage lung cancer. Theoretically, segmentectomy leads to better preservation of lung function than lobectomy, but the risk of incomplete tumor resection is higher, so the indication of segmentectomy has become a focus of debate. This article will introduce the surgical techniques of segmentectomy and summarize the published and unpublished clinical studies on segmentectomy for the treatment of early stage lung cancer.
