- Abstract
Background Sixty-eight percent of patients with pancreatic ductal adenocarcinoma (PDAC) are 65 years and older. Older adults are under-represented in clinical trials and their care is complicated with multiple age-related conditions. Research suggests that older patients can experience meaningful responses to treatment for PDAC. The objective of this study was to evaluate the characteristics, rate of treatment, and survival outcomes of patients with metastatic PDAC (mPDAC) based on age at diagnosis. Materials and Methods Data were extracted for patients diagnosed with mPDAC between January 1, 2015, and March 31, 2020, from the Flatiron Health database. Patients were stratified into 3 age groups: <70 years old, 70-79 years, and ≥80 years. The proportion of patients who received first-line therapy, the types of regimens received in the metastatic setting, overall survival (OS) from the start of treatment were evaluated. Results Of the 8382 patients included, 71.3% (n = 5973) received treatment. Among patients who received treatment 55.5% (n = 3313) were aged <70 years at diagnosis, 33.0% (n = 1972) were 70-79 years, and 11.5% (n = 688) were ≥80 years. Patients ≥80 years of age were more likely to receive gemcitabine monotherapy and less likely to receive FOLFIRINOX. Among first-line treated patients, median OS significantly decreased with age. However, when comparing patients treated with the same first-line regimen, no significant differences in median OS were observed by age. Conclusions This study highlights that older adults with mPDAC can benefit substantially by receiving appropriate levels of treatment.
