AbstractObjective To evaluate the effect of a pretreatment geriatric assessment on the clinical outcomes in older patients with unresectable or recurrent pancreatic ductal adenocarcinoma (PDAC) scheduled to receive gemcitabine (GEM)/GEM+nab-paclitaxel (GnP). Patients Older patients with unresectable PDAC scheduled to receive GEM/GnP who visited Kyorin University Hospital and cooperating institutions were enrolled and followed from April 2015 to March 2020. The maximum observation period was two years. All patients underwent a cancer-specific geriatric assessment (CSGA) and optional geriatric assessment (GA) before treatment initiation and two months after the start of treatment. The patients' background characteristics, tumor progression, tumor site, and regimen (GEM/GnP) were examined in a Cox proportional hazards model. The relationship between the overall survival (OS) and GA score was also determined. Eligible patients (age ≥70 years old with histopathologically confirmed unresectable or recurrent PDAC) were scheduled to receive first-line chemotherapy. Results The performance status (PS) and activities of daily living (ADL)/instrumental ADL (IADL) scores at baseline correlated with the OS. Furthermore, even in cases with normal baseline values, lower Frontal Assessment Battery scores and higher Geriatric Depression Scale-Short Form scores after treatment initiation were significantly correlated with OS. Conclusion The baseline PS, ADL, and IADL may be prognostic factors in older PDAC patients. In addition, a normal frontal lobe function and depression scores prior to treatment initiation that rapidly worsened during treatment were independently associated with a reduced OS. Selecting appropriate interventions and improving the therapeutic environment may prolong the OS in such patients.
