Extended pneumonectomy for non small cell lung cancer--should we still do it?
The aim of the study was to assess the early and late results of extended pneumonectomies in lung cancer patients with T3 and T4 disease. Between Jan. 1995 and Dec. 1999--445 pneumonectomies were performed in patients with lung cancer. In 37 patients without preoperative N2 involvement a standard pneumonectomy was extended to include the following additional resections: chest wall (10), pericardium (9), diaphragm (5), VCS (3), descending aorta (2), left atrium (5), esophagus (1) and tracheal bifurcation (2). The effect of various factors on general mortality and morbidity was analyzed with the use of binary logistic regression. There were two early postoperative deaths (6.8%). Major complications occurred in 10 patients (29%). Overall survival rates at 1, 2, and 3 years were 43, 30 and 24%, respectively. The survival rates for the subgroup with chest involvement only were 50, 42 and 30%, respectively. Eight patients survived beyond the 36 month follow-up. The only factor significantly affecting mortality was incomplete resection, as revealed by postoperative microscopic examination (R1, p<0.05). Extended operations are justified by a relatively low mortality rate and low number of severe postoperative complications, specially in patients with chest wall involvement only. The result of this treatment predominantly depends upon the completeness of the resection.
