Phase II study on combined intravenous and intra-arterial chemotherapy with gemcitabine and mitomycin C in patients with advanced pancreatic cancer.
OBJECTIVE
This prospective phase II study on a combination of intraarterial (i.a.) and systemic chemotherapy was performed to test whether regional chemotherapy may overcome the chemoresistance of pancreatic cancer.


METHODS
One treatment cycle consisted of an i.a. infusion through an angiographic catheter into the celiac artery of 8.5mg/m2 mitomycin C (MMC) and 500 mg/m2 gemcitabine on days 1 and 22, and intravenous infusions of 500 mg/m2 gemcitabine on days 8 and 15. Study-endpoints were overall survival and tumor response as measured by computed tomography (CT). Treatment was continued until disease progression or complete remission on CT.


RESULTS
Thirty-seven treatment cycles were performed in 17 patients. The most frequent side effects were hematological with 18 episodes of grade III/IV toxicities. According to radiographic and tumor marker criteria, four (24%) and seven patients (41%), respectively, demonstrated an objective response. The median actual progression-free and overall survivals were 4.6 and 9.1 months, respectively. Patients without distant metastases had a longer median survival (15 months) than those with distant metastases (7.1 months, p = 0.037).


CONCLUSIONS
This combination treatment was well tolerated and resulted in tumor response rates, median overall- and progression-free survival times superior to systemic gemcitabine chemotherapy, and comparable to the more toxic FOLFIRINOX regimen.
