    Abstract:
    The purpose of this study was to assess retrospectively the sequential treatment of hepatic arterial infusion (HAI) chemotherapy followed by systemic therapy using oxaliplatin plus 5-fluorouracil (5-FU) and leucovorin, namely, FOLFOX, for patients with liver metastases from colorectal cancer. We reviewed 20 patients with unresectable liver metastases from colorectal cancer. Patients were initially treated with HAI chemotherapy until disease progression (5-fluorouracil, 1000 mg/m(2) intra-arterial infusion, weekly) and then with FOLFOX thereafter (FOLFOX4, n = 13; modified FOLFOX6, n = 7). Adverse events, tumor response, and time to progression for each therapy were evaluated retrospectively, and overall survival was estimated. Toxicity of HAI chemotherapy was generally mild. Of 20 patients, adverse events leading to treatment discontinuation occurred in only 1 patient (5%) during initial therapy using HAI chemotherapy, while 9 patients (45%) exhibited adverse events during subsequent FOLFOX therapy. For HAI chemotherapy and FOLFOX, objective response rates were 85.0% and 35.0%, respectively, and median time to progression was 11.6 and 5.1 months, respectively. Median overall survival was 30.1 months. In conclusion, the sequence of HAI chemotherapy followed by FOLFOX is a promising treatment strategy for the long-term use of active chemotherapeutic agents, leading to a superior tumor response and fewer toxic effects in patients with unresectable liver metastases from colorectal cancer.
