Abstract

Liposomal irinotecan plus 5-fluorouracil/leucovorin (nal-IRI + 5-FU/LV) has shown to provide survival benefits for patients with gemcitabine-refractory metastatic pancreatic ductal adenocarcinoma (PDAC) in NAPOLI-1 trial, in which Asian patients experienced more hematological toxicity and subsequent dose modification. A retrospective chart review to investigate the administration pattern, therapeutic efficacy and safety profile of nal-IRI + 5-FU/LV in 44 consecutive patients with gemcitabine-refractory advanced PDAC treated between December 2016 and December 2018 in National Cheng Kung University Hospital, Taiwan. Most of them had metastatic diseases (88.6%), one-line of prior treatment (72.7%), ECOG PS 0-1 (72.7%) and starting dose of nal-IRI at 60 mg/m2 (≈52 mg/m2 irinotecan free-base) in 65.9%. The overall response rate was 9.1%. The median OS was 6.6 months for the entire cohort, and 7.8 and 2.7 months for patients of ECOG PS 0-1 and>2, respectively. The median OS of ECOG PS 0-1 patients with nal-IRI starting doses at 80 mg/m2 (≈70 mg/m2 irinotecan free-base, n = 13) and 60 mg/m2 (n = 19) were 7.5 and 8.4 months, respectively. Thirty-four percent of patients experienced manageable grade 3-4 hematological toxicity. Our results confirm the clinical benefit of nal-IRI + 5-FU/LV for patients of gemcitabine-refractory advanced PDAC with good performance status in a real-world setting.
