NSCLC in the elderly--the legacy of therapeutic neglect

Abstract:
Although the majority of patients diagnosed with non-small cell lung cancer (NSCLC) are elderly, most clinical trials available to guide care either exclude the elderly or underrepresent them. This disregard for the elderly lung cancer patient extends to the clinical realm, where the elderly with lung cancer are less likely to be treated with either curative, or life-extending, palliative therapy. Few elderly-specific phase III trials are available to provide level I evidence. However, subgroup analyses and meta-analyses of large clinical trials enrolling substantial numbers of elderly patients are available to guide care, although these are potentially subject to selection bias. These trials suggest that the fit elderly derive as much benefit from surgery, chemoradiation, and platinum-based doublet chemotherapy as younger patients across all stages of disease. For the less fit elderly, in particular those with limited performance status or significant co-morbidities, less aggressive regimens are likely preferred, with the goal of extending life and delaying or suppressing cancer symptoms. Ultimately, care decisions must incorporate knowledge of the literature, evaluation of the patient's clinical characteristics, and patient priorities. The elderly should be aggressively recruited to clinical trials, including elderly-specific trials and trials of patients with limited performance status and co-morbidities.
Insights
Elderly patients with non-small cell lung cancer (NSCLC) are often excluded from clinical trials. However, evidence suggests fit elderly individuals benefit from standard treatments, while less fit patients may require tailored, less aggressive therapies.
Area of Science:
- Oncology
- Geriatric Medicine
- Clinical Trials
Background:
- Non-small cell lung cancer (NSCLC) predominantly affects the elderly population.
- Elderly patients are frequently underrepresented or excluded from clinical trials guiding cancer care.
- This underrepresentation leads to disparities in treatment for elderly NSCLC patients.
Purpose of the Study:
- To review the evidence guiding treatment decisions for elderly patients with non-small cell lung cancer.
- To highlight the underrepresentation of elderly individuals in clinical trials and its implications.
- To provide recommendations for optimizing care and clinical trial participation for older adults with NSCLC.
Main Methods:
- Analysis of subgroup data and meta-analyses from large clinical trials involving elderly NSCLC patients.
- Review of existing literature on treatment efficacy and outcomes in older adults.
- Consideration of patient-specific factors including performance status and comorbidities.
Main Results:
- Fit elderly patients with NSCLC appear to benefit equally from standard treatments (surgery, chemoradiation, chemotherapy) as younger patients.
- Less fit elderly patients, particularly those with poor performance status or comorbidities, may benefit from less aggressive treatment regimens.
- Treatment decisions should integrate clinical evidence with individual patient characteristics and priorities.
Conclusions:
- Elderly patients with NSCLC should not be excluded from curative or palliative therapies.
- Aggressive recruitment of elderly individuals into clinical trials, including those designed for specific subgroups, is crucial.
- Personalized treatment strategies are essential for optimizing outcomes in the diverse elderly NSCLC population.
