Abstract

BACKGROUND:

Although chemoradiotherapy with full-dose gemcitabine as a strategy for locally advanced pancreatic cancer was expected to optimize local tumor control and prevent distant metastasis, the volume of the radiation field is the critical factor related to toxicities. We are currently developing a novel therapeutic technique to conduct neoadjuvant treatments of intra-arterial chemoinfusion prior to chemoradiotherapy with the aim of tumor volume reduction.

CASE REPORT:

In two patients with locally invasive pancreatic cancer, the pancreatic blood supply was altered under angiographic guidance, and an intra-arterial catheter with a subcutaneous port was left in place for the administration of 5-fluorouracil (5-FU) 1,000 mg/m(2). After shrinkage of the tumor, chemoradiotherapy with gemcitabine 1,000 mg/m(2) was delivered. In both patients, the full-dose gemcitabine was administered concurrently with radiation therapy without severe complications. The patients responded to the treatment with survival times of 42 and 38 months.

CONCLUSION:

Intra-arterial chemoinfusion followed by chemoradiation with full-dose systemic gemcitabine might prove to be a promising therapeutic approach for locally advanced pancreatic cancer. Large prospective Phase II trials of this combination regimen are warranted.
