Hemi-Clamshell Approach for Advanced Primary Lung Cancer

Abstract

Background: The hemi-clamshell approach provides a wide anterior view of the mediastinum, apical dome, and cervicothoracic area. However, only a few reports have been made regarding this technique. Methods: The hemi-clamshell approach was used in 24 patients, of whom 5 had a Pancoast tumor, 15 had mediastinal involvement, and 4 underwent mediastinal lymphadenopathy for left-sided lung cancer. Twenty-one of the patients received preoperative therapy. Results: Twenty-one operations were complete resections. In addition, 12 patients received cardio-vascular reconstruction and 5 a first rib resection. Postoperative major morbidity was 21 % (6/24) and mortality was 4.2 % (1/24). Nine patients died of systemic tumor relapse and 14 patients were alive after a median follow-up of 24 months (range 3 - 68 months) following the initial therapy. The 5-year survival rate of patients with mediastinal involvement was 37 % and that of 13 patients with postoperative stage I or II was 35 %. Conclusions: The hemi-clamshell approach provides a wide exposure allowing a safe and complete removal of lung cancer that involves the mediastinum and apical thoracic dome, leading to a better long-term survival rate for patients with this disease.
