Early and long-term Results of pulmonary resection for non-small-cell lung cancer in patients over 75 years of age: A multi-institutional study

OBJECTIVES: Older lung cancer patients with multiple morbidities are increasingly referred to thoracic surgery departments. The aim of this multicenter study was to analyse the prognostic factors for in-hospital morbidity and mortality and to elucidate the predictors of long-term survival and oncological outcomes. METHODS: We identified 319 patients aged ≥ 75 years who underwent intended curative lung resection for lung cancer in three different thoracic surgery departments between January 2000 and December 2010. RESULTS: Seventy-one patients underwent limited resection, 202 had lobectomy, 16 had bilobectomy and 30 had pneumonectomy. The in-hospital mortality was 6.6%. Chronic renal failure, low respiratory reserve and pneumonectomy were predictors of in-hospital mortality. The mean follow-up time was 3.9 years, ranging from 1 month to 10.4 years. The disease-free survivals at 1, 3 and 5 years were 82, 60 and 47%, respectively. The overall survivals at 1, 3 and 5 years were 86, 59 and 38%, respectively. The long-term overall survival was negatively influenced by pneumonectomy, extended resection, N(1-2) subgroups and pathological TNM stage. CONCLUSIONS: Nowadays, we can consider surgery a safe and justifiable option for elderly patients. Careful preoperative work-up and selection are mandatory to gain satisfactory results. Good long-term results were achieved in elderly patients with early stage who underwent lobar or sublobar lung resection. The role of surgery or other alternative therapies, in patients with advanced stages, extensive nodal involvement and/or requiring extensive surgical resection for curative intent, is still unclear and further studies are certainly needed.
