[Novel chemoradiotherapy for locally advanced pancreatic cancer using arterial infusion chemotherapy following the alteration of peripancreatic blood flow].
Radiotherapy employing intraoperative radiation therapy (IORT) in combination with postoperative external beam radiation therapy (EBRT) is an effective treatment for unresectable pancreatic cancer. To achieve an even greater therapeutic outcome, 13 patients with unresectable pancreatic cancer were treated by IORT in combination with EBRT plus locally intensive arterial infusion chemotherapy. In order to increase drug delivery to the primary tumor, the splenic and major pancreatic arteries, except for the gastroduodenal artery (GDA), were embolized by radiological intervention prior to the arterial infusion chemotherapy, and the administration of gemcitabine, CDDP, and 5-FU to the primary tumors via GDA was followed during EBRT. The values of serum tumor markers were decreased in all patients, and tumor regression was detected on CT scans in 6 patients. The evaluation of survival benefit of this treatment modality is ongoing, but it did not prolong the survival time of patients with second stage lymph node metastases. One of the advantages of this method was able to perform also in charge of hepatic arterial infusion chemotherapy concurrently, but we experienced liver abscess in 2 patients.
