[Treatment strategy and outcomes of invading apical lung cancer].
Invading apical lung cancers are generally the non-small-cell lung cancers (NSCLCs) which involve the apex of the chest wall. These tumors should be classified into 2 types based on the main location of tumor because of the difference of involved surrounding structures ; (1) the superior sulcus tumor origi nally termed Pancoast tumor which involves posterior region of the apex and (2) the anterior apical tumor which involves anterior region of the apex. Previously, these NSCLCs were considered to be inoperable showing a dismal prognosis. With the development of combined modality therapies for locally advanced NSCLCs, the prognosis of invading apical NSCLCs has been improved, especially since intro duction of the neoadjuvant chemoradiotherapy. Surgical resection for invading apical NSCLCs is 1 of challenging procedures for thoracic surgeons. The point is the anatomical complication of the small apex surrounding vital structures. Several approaches have been developed such as the posterior Paul-son's approach or anterior Masaoka's approach. In particular, the approach from anterior chest has been modified or devised to achieve safe and complete resection of tumors invading anterior structures like subclavian vessels. In this article, we reviewed our 13 cases of invading apical NSCLCs, especially from the view point of surgical approach. Thoracic surgeons should understand the properties of each approach and master them for complete resection avoiding serious complications.
