Introduction L ung cancer has the highest rate of mortality among all cancers with more than 80% diagnosis of non-small-cell lung carcino-ma (NSCLC) [1, 2]. A new treatment approach for a wide range of high-risk patients with early-stage NSCLC who do not have proper respiratory conditions for lobectomy or pneumonectomy is wedge re-section plus low-dose-rate (LDR) permanent implant brachytherapy [3, 4, 5]. In this technique, a wedge-shaped piece of lung is removed by segmentectomy, and an

The implants are Original ABSTRACT Background: A new treatment approach for most patients who have undergone
