Prospective phase II trial of combination hepatic artery infusion and systemic chemotherapy for unresectable colorectal liver metastases: Long term results and curative potential.

Journal Article (Journal Article)

BACKGROUND/OBJECTIVES: Combination hepatic artery infusion (HAI) and systemic (SYS) chemotherapy for unresectable CRLM results in high tumor-response rates. This study represents an update of long-term survival and conversion to resectability in patients with unresectable CRLM treated with HAI and SYS chemotherapy in a phase II study. METHOD: The primary endpoint was complete resection. Multivariate and landmark analysis assessed the effect of complete resection on progression-free (PFS) and overall survival (OS). RESULTS: From 2007 to 2012, 64 patients with median of 13 tumors were enrolled; 67% had prior chemotherapy. 33 patients (52%) were converted to resection. Median follow-up among survivors was 81 months. Median PFS and OS were 13 and 38 months, respectively, with 5-year-OS of 36%. Chemotherapy-naïve patients had 5-year-OS of 51%. Conversion to resection was the only independent factor prognostic of improved PFS and OS. Nine of 64 patients (14%) are NED (five since initial resection, three after resection of recurrent disease, one from chemotherapy alone) at median follow-up of 86 months from treatment initiation, and 72 months from last operative intervention. CONCLUSION: Combination HAI and SYS is an effective therapy for high-volume unresectable CRLM, resulting in a high rate of resection, long-term survival, and the potential for cure.
