Short and mid-term outcomes of multimodal treatment for locally-advanced non-small cell lung cancer in elderly patients.

Abstract

Multimodality treatments are effective for locally advanced non-small cell lung cancer (LA-NSCLC) showing benefits in overall (OS) and disease-free survival (DFS), but these options are frequently denied to elderly patients. The objectives of this retrospective study were: to investigate mortality, morbidity and oncological outcomes of pulmonary resection after induction therapy (IT) for NSCLC in elderly patients. We divided the cohort into two: patients < 70years (group A) and patients ≥70years (group B). A multivariable logistic regression was built to identify factors associated with morbidity. 77 patients underwent pulmonary resection after IT, 27 were aged ≥70years. Type of chemotherapy, surgical procedures, pathological stages were comparable between the two groups, while the preoperative use of chemo-radiation therapy regimen was more frequent in group A (p = 0.027). In-hospital mortality was similar, while the percentage of patients with complications (38% vs 48.1%, p = 0.47) and the complication rate (50% vs 77%, p = 0.01) were higher in group B, but the severity of complications was comparable. The multivariable analysis did not identify any risk factors associated with morbidity. OS at 3years and DFS at 2years were not different (61% vs 48.5%, p = 0.64; 61.7% vs 44%, p = 0.393). Lung resection for LA-NSCLC after IT can be performed safely in selected elderly patients with favourable postoperative and mid-term oncological results.
