Abstract: Objective : To discuss the surgical treatment and perioperative management of lung cancer in senior pa-tients. Methods : From November 1997 to November 2007, 95 patients over 70 years old (70 males and 25 fe-males, with an average age of 73.5) with lung cancer received surgical treatment in our department. We retro-spectively analyzed their medical records. Before surgery, these patients'forced expiratory volume in onesecond (FEV1), diffusing capacity for carbon monoxide (DLCO), and left ventricular ejection fraction (LVEF)were tested and an exercise test was performed to evaluate the surgical risk. Three patients received pneu-monectomy, 70 patients had lobectomy, 20 patients had limited pulmonary resection and 2 patients had ex-ploratory thoracotomy. Postoperatively, 12 patients had delayed extubation because of hypoxemia and weresupported by mechanical ventilation for a smoother recovery from anaesthesia. Postoperative tachyarrhythmi-a was treated with beta-1 receptor blocker and amiodarone. Results : According to the pTNM staging, 41.2% ofthe patients were of stage I. No patients died during the operation. The perioperative mortality rate was 4.2%and the postoperative morbidity was 44.2%. Compared with those patients who had DLCO≥60%, patientswith DLCO<60% had a remarkably higher rate of postoperative complications ( P =0.004). The postoperativemortality of patients assisted by mechanical ventilation during anaesthesia recovery was lower than that ofthose without mechanical ventilation assistance during anaesthesia recovery ( P =0.02). Beta-1 receptor block-er and amiodarone successfully treated postoperative tachyarrhythmia in 94.1% of the patients that had it. Conclusion : Senior patients with lung cancer benefit from strict preoperative evaluation, the use of proper sur-gical procedures and active management of postoperative complications.
