Research progress of anatomical subsegmentectomy and combined subsegmentectomy in the treatment of early non-small cell lung cancer / 沈阳医学院学报

ABSTRACT

Lung cancer is one of the malignant tumors with the highest mortality and the fastest growing incidence,which seriously threatens human life and health.With the popularization of low-dose spiral CT and the enhancement of public awareness of physical examination,more and more ground-glass nodules have been detected.Accumulating studies have shown that for patients with nodules diameter≤2 cm and ground-glass opacity≥50% ,under the condition of ensuring the cutting edge,thoracoscopic sublobectomy or subsegmentectomy can more effectively preserve the lung function of patients,and has gradually become the recommended surgical method.In recent years,with the continuous improvement of thoracoscopic surgery technology,thoracoscopic subsegmentectomy and combined subsegmentectomy have been gradually carried out.Compared with lobectomy and segmentectomy,subsegmental resection can retain more normal lung tissue and reduce the loss of lung function under the condition of ensuring the safe cutting edge.However,thoracoscopic subsegmental resection requires a higher level of surgical technique and anatomical knowledge for the operator,and is rarely reported in relevant literature.Therefore,this article reviews the progress of anatomical subsegmentectomy and combined subsegmentectomy in the treatment of early non-small cell lung cancer.
