Hepatic arterial infusion chemotherapy for post-operative liver metastases from pancreatic cancer in a patient with leukocytopenia: A case report.

Here, we present a case of post-operative liver metastases from pancreatic head cancer in a patient with leukocytopenia, who was safely treated by hepatic arterial infusion (HAI) chemotherapy consisting of gemcitabine and 5-FU. The patient was a 61-year-old woman who underwent pancreaticoduodenectomy for pancreatic head cancer, but was found to be an unsuitable candidate for adjuvant systemic chemotherapy due to the presence of leukocytopenia. Five months after surgery, a follow-up CT revealed two liver metastases. Intravenous systemic chemotherapy was also contraindicated due to the leukocytopenia. In the apparent absence of recurrence, excepting the liver metastases, we decided to administer HAI chemotherapy, which had already been administered following the curative surgery. HAI chemotherapy has been shown to be associated with a lower incidence of systemic side effects. Gemcitabine at a dose of 400 mg was administered via a bedside pump and infused over 30 min. After gemcitabine infusion, 250 mg of 5-FU was infused continuously over 24 h from days 1 to 5. This comprised 1 cycle of therapy. The treatment cycles were continued biweekly. After 10 cycles without severe side effects, it was found that though the size of the metastatic tumors was not reduced, tumor vascularity was. However, after the 13th treatment cycle, local recurrence and lymph node metastases were detected. By this time, the patient had recovered from the leukocytopenia, and could thus be administered systemic chemotherapy. In conclusion, HAI chemotherapy is useful and safe for the treatment of malignancies confined to the liver, even in cases where the patient is in a reduced physical condition.
