Early Interesting Observations inEarly Interesting Observations in Regards to the Frail Elderly
• Overall mortality < 1%
• 2% mortality if FEV-1 < 1 liter
• 10% mortality if Karnofsky scale < 8(unable to carry on normal activity)

Risk of Operative Mortality inRisk of Operative Mortality in Elderly is Primarily Respiratory Risk
• Kyphosis
• Decreased excursion of lower ribs
• Increased dependence on diaphragmsdiaphragms
• Aspiration

Potential Options
• Always acknowledge “Do nothing” is an option• A diagnosis should be made
St i h ld b l t d t id th• Staging should be completed to guide therapy• Intervention must be based on strength or frailty
• Cancer treatment options:– Surgery (lobectomy, segmentectomy)– Lesser surgery (wedge resection)Lesser surgery (wedge resection)– No surgery but local ablation – Radiation therapy

Second Operative Risk Factor for Elderly Patients is Amount of Lung Parenchyma Removed
• Lobectomy:• Lobectomy:May remove too much lung in elderlyHigher morbidityVery low recurrence rate (6%)
• Thoracoscopic Wedge:Less than 1% mortality rate, even in elderlyLess morbidityMay have a 17% local recurrence rate

Thus, American surgeons are able to tailor surgery to those less than 75 years of age, but are not properly selecting patients over age 75.
