Place de la chirurgie à visée curative dans le traitement du cancer bronchique non à petites cellules. ہ propos de 969 cas

SummaryPurpose pective analysis of the results of radical surgery in a series of 969 patients presenting with non-small cell lung cancer. ts et methods pril 1984 to December 1981, 969 patients underwent radical surgery with mediastinal node dissection for non-small cell lung cancer. Surgery included 507 pneumonectomies, 447 lobectomies and 15 segmentectomies (for patients suffering from respiratory failure). s te of intrahospital mortality was 4.3%. The rate of crude survival at 5-years was 45.8 %. The tumor size (P = 0.004) and visceral pleura ruptures (P = 0.01) were significantly correlated to the 5-year survival rate that was reaching 56% for patients with no demonstrable metastasis to regional lymph nodes (N0), 46.6% for patients with metastasis to lymph nodes in the peribronchial or the ipsilateral hilar region (N1), and 20,8% for patients with metastasis to the ipsilateral mediastinal and subcarinal lymph nodes (N2) (P = 0.001). In case of stage N2 cancer, the 5-year survival rate was 28.7% when only one anatomical level was involved, and 8.7% when more than one anatomical level was involved (P < 0.0001). sion in prognostic factor was nodal involvement.
