Comparative StudyRisk factors for morbidity after pulmonary resection for lung cancer in younger and elderly patients.
The aim of this study was to evaluate the perioperative morbidity, mortality, and risk factors for morbidity after lung cancer resection in younger and elderly patients. This study retrospectively reviewed 1073 patients with non-small cell lung cancers (NSCLC) who underwent pulmonary resection. The risk factors for morbidity were analyzed independently in groups of 664 younger (<70 years) patients and 409 elderly (≥ 70 years) patients. ⋯ Multivariate analyses revealed the risk factors for morbidity to be % forced expiratory volume in 1 s (FEV(1)), the extent of pulmonary resection and tumor histology in the younger group, and smoking, hypertension, renal insufficiency and % diffusing capacity of the lung to carbon monoxide (DLCO) in the elderly group, respectively. In conclusion, the rate of morbidity and mortality in elderly patients were similar to those observed in younger patients. However, perioperative management should be cautiously performed while taking into account the risk factors for morbidity especially in elderly patients because they frequently have various co-morbidities.

Blood flow measurements within optic nerve head during on-pump cardiovascular operations. A window to the brain?
This observational study is conducted to demonstrate optic nerve head (ONH) blood flow alterations during extracorporeal circulation (ECC) in routine on-pump cardiovascular operations in order to evaluate the perfusion status of important autoregulatory tissue vascular beds during moderate hypothermia. Twenty-one patients free from eye disease were prospectively enrolled in our database. Perioperative ONH blood flow measurements were performed using a hand-held portable ocular laser Doppler flowmeter just after administration of general anesthesia and during cardiopulmonary bypass (CPB) upon the lowest temperature point of moderate hypothermia. ⋯ This angiokinetic approach can detect changes of flow within autoregulatory vascular tissue beds like ONH, thus creating a 'window' on cerebral microvasculature. ONH blood flow is reduced during CPB. Our data suggest that it is of paramount importance to avoid extracorporeal prolongation even in moderate hypothermic cardiovascular operations.

Surgical treatment of non-small cell lung cancer in octogenarians.
As the European population ages, surgeons are regularly faced with octogenarians with resectable early stage non-small cell lung cancer (NSCLC). We compared our experience with those reported in the literature to comprehend the feasibility, outcomes and lessons learned regarding surgical treatment. We reviewed octogenarians who underwent lung resection for NSCLC in the past nine years in our Department. ⋯ The overall complication rate was 30.0%, with a major complication rate of 2.5%. Actuarial cancer-related survival rates at one, three and five years were 90%, 44% and 36%, respectively, with a statistically-significant correlation with pathological stage. Octogenarians may benefit from surgical treatment of NSCLC with an acceptable morbidity and mortality rate, if an accurate preoperative selection is pursued.
