Resection of the First Rib With Preservation of the T1 Nerve Root in Pancoast Tumors of the Lung.

Abstract

Surgical outcomes for Pancoast (superior sulcus) tumors of the lung have significantly changed during the last few decades and have improved with use of curative-intent surgery by utilizing en bloc complete resections. A retrospective analysis was conducted of 11 selected patients treated at Moffitt Cancer Center from 2007 to 2016. Data from patient records were collected and analyzed. All 11 patients with a Pancoast tumor involving the first rib had their T1 root preserved at surgery. In 10 patients (90.9%), the tumor was removed en bloc. Clear margins of resection were documented in 4 cases (36.0%). No patient developed postoperative hand weakness, but 3 patients (27.3%) had minor postoperative complications, including air leak, chylothorax, and pericardial effusion. One iatrogenic injury to the subclavian artery was reported during surgery; the injury was subsequently repaired. No operative mortality was reported. Radical resection of Pancoast tumors is considered to be safe, and preserving the T1 nerve root provides more favorable, functional outcomes.
