title: [A clinical study on superior sulcus tumors].
abstract: Twenty nine patients with superior sulcus tumors (26 men and 3 women) were studied. The incidence was 2.1% of 1350 patients with lung cancer. The mean age was 66.2 years, and 27 patients (93.1%) had a history of smoking (B.I. = 1193.7). There were 10 adenocarcinomas, 9 squamous cell carcinomas, 5 large cell carcinomas 4 small cell carcinomas, and 1 that could not be classified. Fifteen patients (51.7%) had Stage IV disease on admission. Eight patients (27.6%) presented with symptoms outside the chest. Pancoast syndrome was recognized in 9 patients (31.0%). In 15 patients (51.7%) the diagnosis was made by transbronchial biopsy and in 10 patients (34.5%) it was made by echoguided needle biopsy. Tumors were located in a posterior lesion in 13 patients (44.8%). Twenty patients were given radiation therapy. Clinical staging, irradiation, and surgical treatment were related to the length of survival. The median survival time was 7 months.
