Surgical treatment of bronchogenic carcinoma: a retrospective study of 720 thoracotomies

Abstract

Seven hundred and twenty patients with primary bronchogenic carcinoma were operated on at the Pellenberg Clinic, K.U. Leuven, Belgium, between January 1, 1970, and January 1, 1985. Almost 45% of the resections were pneumonectomies and 47% were lobectomies. Mortality was 6.9% and 2.9%, respectively. Patients with squamous cell carcinoma (Stages I and II) who underwent lobectomy or pneumonectomy had an absolute 5-year survival rate of 52.8% (93/176); it was 21% (4/19) in the T3 N0/N1 subgroup. Patients with adenocarcinoma who underwent a lobectomy had a 5-year survival rate of 49% (26/53) in the T1/T2 N0 group and of 27% (3/11) in the T1/T2 N1 group. Only 13.6% (3/22) of patients survived 5 years if a pneumonectomy had to be performed. Only 1 in 22 N2 patients survived 5 years after resection.
