Summary
Background
As life expectancy increases, more adults aged ≥80 years are diagnosed with early-stage lung cancer. Often these patients are excluded from screening programs and clinical trials due to concerns about comorbidities and surgical risk as evidence on surgical outcomes and quality of life (QoL) remains limited. We aimed to compare postoperative outcomes, survival, and QoL between octogenarians and younger patients undergoing surgery for Stage IA NSCLC.
Methods
We included patients with stage IA non-small cell lung cancer from the Mount Sinai Health System enrolled in the prospective Initiative for Early Lung Cancer Research on Treatment (IELCART) study. Octogenarians (80 years and older) were compared to younger patients in terms of clinical presentation, type of surgery, postoperative outcomes, and survival. Quality of life was assessed using physical and mental health scores at baseline and at 1, 6, and 12 months after surgery. Lung cancer–specific and overall survival were analyzed using Kaplan–Meier methods.
Findings
Among 884 patients, 114 (12.9%) were octogenarians. Compared to 770 younger patients, octogenarians had similar comorbidities but underwent more frequently sublobar resections [90/114 (78.9%) vs. 485/770 (62.4%), p = 0.030] and had higher complication rates [46/114 (40%) vs. 168/770 (22%), p < 0.0001], particularly cardiovascular. Intensive care unit admissions and readmissions were slightly more frequent. In both age groups, physical and mental health declined at two months but improved by twelve months, with no significant differences. Five-year overall- and lung cancer-specific survival rates were similar between octogenarians and younger patients (overall: 84.2% vs. 87.3%, lung cancer–specific survival: 94.4% vs. 94.5%).
Interpretation
Among octogenarians with early-stage NSCLC, surgical treatment was associated with favorable safety and long-term quality-of-life outcomes in carefully selected patients.
Funding
This study was supported by generous grants from the Simons Foundation (International, Ltd.).
