p53 in relation to therapeutic outcome of locoregional chemotherapy in pancreatic cancer.
Since celiac artery infusion (CAI) led to an increase in survival in palliative chemotherapy in pancreatic cancer, we treated 26 patients with adjuvant CAI following resection for advanced pancreatic cancer. Catheters were placed angiographically into the celiac artery and remained there for five consecutive days. One cycle of chemotherapy consisted of mitoxantrone, 5-fluorouracil (5-FU), folinic acid, and cis-platinum. This treatment was repeated five times in monthly intervals. Median survival times in patients who received CAI are 21 months for all patients, whereas in patients who did not receive adjuvant treatment median survival is 10.5 months. In all patients p53 expression of the carcinomas was determined by immunohistochemistry. In 11/26 patients a p53 overexpression was observed. Although p53 overexpression turned out to be associated with poor prognosis in the patients who underwent adjuvant regional cancer treatment, p53 is not a sufficient prognostic parameter in pancreatic carcinoma, since p53 overexpression was more frequent in undifferentiated tumors and in palliative resected tumors.
