[p53 expression and response to hepatic intraarterial infusion chemotherapy in patients with colorectal cancer metastasis to liver].
We have reported that hepatic artery infusion (HAI) chemotherapy with 5-fluorouracil for unresectable colorectal liver metastasis may lead to improved overall survival for some patients compared with controls. The aim of this work is to determine whether p53 nuclear protein expression examined by immunohistochemical technique could predict the outcome of patients treated with HAI chemotherapy. No significant difference was found in the response rate (p > .99, Fisher's exact method.) and median survival time (12 months in patients with p53-positive tumors and 11 months with negative tumors). Our results indicate that HAI chemotherapy is an effective treatment for liver metastasis regardless of p53 nuclear protein expression.
