Abstract

Objectives: The majority of Americans diagnosed as having cancer are older than 65 years. They are, however, less likely than younger patients to receive chemotherapy. Our study aimed to better understand the specific reasons for acceptance or refusal of chemotherapy in older adults with cancer.

Methods: An anonymous cross-sectional survey was distributed during a 6-month study period in a cancer center and an outpatient geriatric medicine faculty practice to patients at least 50 years old with cancer or to their family members. Data collected included reasons for refusal or acceptance, stage/type of cancer, and demographics. The association between chemotherapy refusal or initiation and these factors was assessed using the Fisher exact test.

Results: Among the 37 respondents meeting the inclusion criteria, 78.4% were patients and 21.6% were family members. The following factors were significantly associated with chemotherapy decision: perceived chemotherapy benefit ( P < 0.001), trust in the doctor’s recommendation ( P = 0.013), social support ( P = 0.018), marital status ( P < 0.001), sex ( P = 0.037), race/ethnicity ( P = 0.021), and whether respondents had a family member or friend who had previously received chemotherapy ( P = 0.040). In contrast, none of the clinical variables, such as stage of cancer, previous receipt of chemotherapy, or interest in complementary/alternative medicine showed significant association with a patient’s decision to accept or refuse chemotherapy treatment.

Conclusions: Chemotherapy decisions made by older adults appear to be associated with demographic and social factors rather than with medical information. Recognizing the influence of these factors for older patients with cancer may help hematologists and oncologists to proactively address specific barriers and explore concerns regarding chemotherapy in older patients whose quality of life and longevity may be affected by treatment.
