| pubmed-article:7073376 | pubmed:abstractText | A retrospective evaluation of 199 consecutive patients undergoing resection for lung cancer revealed a significantly shorter long-term survival for those in whom empyema developed postoperatively. The overall five-year survival for the empyema group was 24% compared with 35% in the control group (patients without empyema), and the median survival was 15 months for the control group. These differences in survival were not found among patients with Stage I lung cancer. Pneumonectomy proved to be the main risk factor for the occurrence of empyema after operation, but a minor risk factor was the anatomical extent of disease. this correlation may be explained by major surgical contamination or manipulation as well as by lower immunological host reaction, all related to the extent of the tumor. A lower immunological defense could also explain the worse outcome for patients with Stage II or III lung cancer in whom empyema developed postoperatively. | lld:pubmed |
