BackgroundTreatment of metastatic pancreatic adenocarcinoma (mPAC) relies on chemotherapeutic regimens. We investigated patterns of first-line and second-line treatment choices, their geographical variation between European countries, and alignment with current European recommendations.MethodsThis retrospective, observational chart review study was conducted between July 2014 and January 2016. Physicians were recruited from nine European countries. Patient data were collected in electronic patient record forms (PRFs) by physicians managing patients with mPAC. Patients with a current mPAC diagnosis aged ≥18 years old who had completed first-line therapy during the study period were included.ResultsParticipating physicians (n=225) completed 2565 PRFs. The vast majority of PRFs were from France, Germany, Italy, Spain and the UK. Most patients (86.6%) had stage IV disease at diagnosis. The most common first-line treatments were FOLFIRINOX (5-fluorouracil, leucovorin/folinic acid, irinotecan and oxaliplatin) (35.6%), gemcitabine+nab-paclitaxel (25.7%) and gemcitabine monotherapy (20.5%). Physicians in France and the UK prescribed FOLFIRINOX more frequently than gemcitabine+nab-paclitaxel. Gemcitabine-based therapies were more widely used at second-line, although 5-fluorouracil-based therapies were preferred in Italy and Spain, where gemcitabine-based treatments were more frequently selected for first-line. For patients receiving first-line modified FOLFIRINOX, second-line gemcitabine monotherapy was preferred in the overall population (45.9%).ConclusionAlthough treatment choices for patients with mPAC varied between countries, they align with current European guidelines. Factors including drug availability, reimbursement, patient characteristics, physician preference and prior first-line therapy affect treatment choices. Approved, recommended therapies for patients who progress following first-line treatment are lacking. These findings may influence the development of effective treatment plans, potentially improving future patient outcomes.
