Hepatic Arterial Infusion Chemotherapy for Liver Metastases Following Standard Chemotherapy for Pancreatic Cancer

A 65-year-old man diagnosed with locally advanced pancreatic cancer underwent distal pancreatectomy and combined portal vein resection. One month after surgery, contrast-enhanced magnetic resonance imaging revealed multiple liver metastases. We administered two courses of gemcitabine plus nab-paclitaxel combination therapy followed by 17 modified FOLFIRINOX courses. However, the response was insufficient, and the patient thereafter developed grade 3 neutropenia, which made it difficult to continue the treatment regimen. As a result, we administered hepatic arterial infusion chemotherapy comprising gemcitabine plus 5-fluorouracil because the residual tumor was limited to liver metastases. The progression-free survival period was 7 months, and no drug-related adverse effects were noted during the treatment.
