Age Differences in Clinical Trial Understanding in Non-Hodgkin Lymphoma Patients

Area of Science:

• Oncology
• Clinical Trials
• Geriatric Medicine

Background:

• Clinical trials are crucial in cancer care but often misunderstood by patients.
• Limited research exists on age-related differences in clinical trial comprehension, particularly in older adults with indolent non-Hodgkin lymphoma (NHL).

Purpose of the Study:

• To investigate age-based differences in understanding the goals of clinical trials among patients with indolent non-Hodgkin lymphoma (NHL).

Main Methods:

• Participants aged 21 years and older with NHL were recruited.
• Age was categorized into <65 and ≥65 years.
• A four-item survey assessed understanding of clinical trial goals, with responses analyzed by age using Chi-square tests.

Main Results:

• Older patients (≥65 years) were significantly more likely than younger patients (<65 years) to express uncertainty ('I don't know') regarding clinical trial objectives.
• Specifically, older adults showed less understanding of goals related to reducing (41.4% vs. 13.3%) and preventing worsening of lymphoma (41.4% vs. 13.3%).
• These findings persisted even when analyzing patients under active surveillance.

Conclusions:

• Older adults may possess a less detailed understanding of clinical trial objectives compared to younger individuals.
• Developmentally appropriate interventions are recommended to enhance clinical trial comprehension among older cancer patients.
• Future studies should explore the link between age, clinical trial understanding, and enrollment using validated measures in diverse populations.
