With increasing longevity, altered demographics of the lung cancer population, and preoperative interventions to enhance the efficacy of surgical therapy, increasing numbers of elderly people will present for anesthesia and pulmonary resection.
The geriatric population often exhibits wide disparity between chronologic and physiologic senescence which is underscored by data indicating that outcome following lung resection for cancer is influenced more by tumor stage, preoperative functional status and comorbidities than age alone. Nonetheless, the normal process of cardiopulmonary aging can limit the physiological reserve necessary to compensate for perioperative stress even in otherwise healthy elderly patients. Data indicate a relatively favorable risk-benefit relationship for lung resection in the elderly given the poor prognosis for patients undergoing palliative care or chemotherapy or radiation alone. Emerging experience now suggests that minimally invasive surgical techniques for the treatment of lung cancer may parallel conventional thoracotomy in terms of oncologic efficacy while decreasing perioperative morbidity in the elderly.
The combination of an aging population, recent advances in neoadjuvant therapies, data supporting the oncologic efficacy of resection, and minimally invasive surgical techniques strongly suggests that more elderly patients will be candidates for surgical management of their lung cancer, thus presenting anesthesiologists with unique challenges.
随着寿命延长、肺癌患者人口统计学特征改变以及为提高手术治疗效果而采取的术前干预措施,越来越多的老年人将接受麻醉和肺切除术。
老年人群常表现出实际年龄与生理衰老之间的巨大差异,有数据表明,肺癌肺切除术后的结果受肿瘤分期、术前功能状态和合并症的影响大于年龄本身,这突出了这种差异。尽管如此,即使是原本健康的老年患者,心肺衰老的正常过程也会限制补偿围手术期应激所需的生理储备。数据表明,鉴于接受姑息治疗、单纯化疗或放疗的患者预后较差,老年患者肺切除的风险效益关系相对有利。新出现的经验表明,治疗肺癌的微创手术技术在肿瘤学疗效方面可能与传统开胸手术相当,同时可降低老年人围手术期发病率。
人口老龄化、新辅助治疗的最新进展、支持手术切除肿瘤学疗效的数据以及微创手术技术的结合,强烈表明更多老年患者将成为肺癌手术治疗的候选者,从而给麻醉医生带来独特挑战。
