Abstract

Sleeve lobectomy for non-oat cell carcinoma involving a major bronchus preserves functioning lung tissue and, in carefully selected patients, provides long-term survival comparable to pneumonectomy. Seventy patients underwent sleeve lobectomy between 1967 and 1978. Twenty-seven patients were considered compromised (Group I) because they had severe respiratory impairment which contraindicated pneumonectomy. Forty-three patients were considered uncompromised (Group 2) and underwent elective sleeve lobectomy. Seventy patients with a similar non-oat cell carcinoma involving the proximal bronchi underwent pneumonectomy (Group 3) during this period. Perioperative complications occurred more frequently in Group 1 (59%) than in Group 2 (21%) or Group 3 (23%). Both periopeative mortality rate and the incidence of bronchial disruption (bronchovascular and bronchopleural fistulas) were higher in Group I (19% and 22%) than in Group 2 (9% and 5%) or Group 3 (3% and 7%). Survival depended primarily on the surgeon's ability to perform a complete resection of the tumor. An incomplete resection resulted when tumor was found in the highest lymph node or in the last bronchial resection margin when paraffin sections were reviewed. The 5 year survival rate was 18% for compromised patients (Group 1) who underwent complete resection, and there were no survivors among patients undergoing incomplete resections. Uncompromised patients ( Group 2) had a 5 year survival rate of36% with complete and 12% with incomplete resections. Pneumonectomy patients (Group 3) had a 64% 5 year survival rate with a complete resection and 16% with an incomplete resection. The stage of the disease at the time of operation had a profound effect on the survivail. There was no difference inthe 5 and 8 year survival rates between uncompromised patients undergoing sleeve resection ( Group 2) and patients undergoing peneumonectomy (Group 3) for comparable stage of their disease. A careful pre- and postoperative functional assessment revealed that pulmonary performance was improved in 44% of Group 1, 63% of Group 2, and only 14% of Group 3 patients. Patients wiht impaired pulmonary reserve underwent sleeve lobectomy with an adequate disease-free interval when complete tumor excision was possible. Uncompromised patients whose extensive disease required incomplete resection had palliation by sleeve lobectomy equivalent to that by pneumonectomy. When complete t-mor resection was possible, patients with uncompromised pulmonary reserve had a perioperative complication rate and long-term survival equivalent to that of pneumonectomy while preserving pulmonary parenchyma, which permitted an improvement in postoperative pulmonary performance.
