Surgical resection and long-term survival for octogenarians who undergo surgery for non-small-cell lung cancer

Abstract

Purpose: An increasing proportion of newly diagnosed non-small-cell lung cancer (NSCLC) patients are octogenarians. It has been questioned whether older patients benefit from surgical resection of lung cancer to the same extent as younger patients.

Patients and methods: We conducted a single-institution, retrospective analysis of patients newly diagnosed with NSCLC from 2000-2006, who underwent surgical resection of their lung cancer in Hoag Hospital. We compared resection and survival rates for patients who were age 80 years or older to younger cohorts and determined their stage distribution, rates of surgery, and actuarial survival by age-defined cohort. Of 1293 total patients, 17.2% were age 80 years or older; 36.1%, age 70-79 years; 29.2%, age 60-69 years; 12.9%, age 50-59 years; and 4.6%, under age 50. Of these patients, 482 underwent surgical resection. Surgical procedures included 400 lobectomies, 23 pneumonectomies, and 59 wedge resections.

Results: The proportion of patients who had local disease at diagnosis was higher for octogenarians compared with younger patients (33.6% vs. 26.6%; P = .021), but the resection rate for octogenarians was lower (64% vs. 83%; P = .0003). For patients determined to have local- or regional-stage disease, resection rates were 52% versus 67.9% (P = .0007). However, survival curves for patients who underwent surgical resection were similar for all five cohorts with 5-year survival rates of 62%, 53%, 63%, 63%, and 79% from oldest to youngest.

Conclusion: Non-small-cell lung cancer patients < 80 years of age were less likely to undergo potentially curative surgery, but survival for octogenarians who did undergo surgical resection was comparable to younger age groups. Such patients should not be denied potentially curative surgery simply because of age.
