Lung cancer in octogenarians: factors affecting long-term survival following resection.

OBJECTIVE: To identify factors associated with long-term survival following pulmonary resection for lung cancer in patients 80 years of age or older. METHODS: The medical records of all patients >or=80 years, who underwent pulmonary resection for lung cancer from 1985 to 2002, were reviewed. RESULTS: There were 294 patients (192 men, 102 women). Median age was 82 years (range 80-94 years). Overall 1-, 2-, and 5-year survival was 80%, 62%, and 34%, respectively. Histologic subtype, diabetes, renal insufficiency, prior myocardial infarction, congestive heart failure or stroke were not significantly associated with differences in 5-year survival. Female gender was associated with increased survival (36.2% vs 32.7% at 5 years, p=0.04). Extent of preoperative forced expiratory volume in 1s (FEV1) limitation did not influence survival. However, there were no 5-year survivors amongst patients with dyspnea as their presenting chief complaint, whereas there was a 35% 5-year survival in patients presenting without dyspnea (p<0.001). Five-year survival by pathologic stage was IA, 48%; IB, 39%; IIA, 17%; IIB, 23%; IIIA, 9%; and IIIB, 0% (p<0.001). Five-year survival of patients undergoing a lobectomy was 42% versus 11% for pneumonectomy (p<0.001). CONCLUSIONS: Meaningful long-term survival is obtainable in elderly patients undergoing surgical resection for lung cancer. Careful patient evaluation and selection is necessary to identify patients who will benefit most from resection. Shorter survival was observed in male patients and those presenting with dyspnea. As could be expected, survival was also dependent on extent of resection and initial pathologic stage.

Lung cancer in octogenarians: factors affecting morbidity and mortality after pulmonary resection.

BACKGROUND: Predictors of morbidity and mortality after pulmonary resection for lung cancer in patients 80 years of age or older are unknown. METHODS: The medical records of all patients 80 years of age or older who had pulmonary resection for lung cancer from January 1985 through September 2004 were reviewed. RESULTS: There were 379 patients (248 men, 131 women). Median age was 82 years (range, 80 to 95 years). Pneumonectomy was performed in 25 patients (6.6%), bilobectomy in 7 (1.8%), lobectomy in 240 (63.3%), segmentectomy in 29 (7.7%), and wedge excision in 78 (20.6%). The cancer was squamous cell carcinoma in 143 patients (37.7%), adenocarcinoma in 166 (43.8%), bronchoalveolar cell carcinoma in 47 (12.4%), and other in 23 (6.1%). Complications occurred in 182 patients (48.0%). These included atrial fibrillation in 75 patients, pneumonia in 27, and retained secretions requiring bronchoscopy in 37. Morbidity predictors were male sex (odds ratio [OR], 1.6), hemoptysis (OR, 2.3), and previous stroke (OR, 3.8). Asymptomatic patients had a significantly decreased probability of complications (OR, 0.56). Operative mortality was 6.3% (24 of 379); significant predictors were congestive heart failure (OR, 6.0) and prior myocardial infarction (OR, 4.3). Factors not associated with mortality included previous myocardial revascularization, renal insufficiency (creatinine >1.5 mg/dL), and diabetes mellitus. CONCLUSIONS: Pulmonary resection for lung cancer in octogenarians is feasible. Congestive heart failure and myocardial infarction, however, correlated with a significant increase in mortality. Prior myocardial revascularization, renal insufficiency, and diabetes were not associated with increased morbidity and mortality.

Lymphadenectomy in metastasectomy.

Although surgery for pulmonary metastases does not benefit a significant number of patients, PM should continue to be offered to patients whose primary tumor is controlled and who have acceptable operative risks. For a survival benefit to be achieved, all extrathoracic and pulmonary metastases must be amenable to complete surgical resection. We have shown that the presence of metastatically involved lymph nodes discovered during PM adversely effects survival in patients undergoing curative PM. We therefore continue to recommend complete mediastinal lymphadenectomy at the time of PM to define the patient's prognosis and perhaps to guide adjuvant therapy.
