[Hepatectomy combined with cryoablation and ethanol injection for unresectable multiple liver metastases from colorectal cancer].

Objective: To evaluate the efficacy and safety of hepatectomy combined with cryoablation and ethanol injection in patients with unresectable multiple liver metastases from colorectal cancer.

Methods: Clinical data of 23 patients with multiple liver metastases form colorectal cancer in the Affiliated Tumor Hospital of Guangzhou Medical College between January 2005 and December 2010 were analyzed retrospectively. There were 15 males and 8 females with average age of 52.

Inhibitory effect of modified citrus pectin on liver metastases in a mouse colon cancer model.

Aim: To discuss the expression of glactin-3 in liver metastasis of colon cancer and its inhibition by modified citrus pectin (MCP) in mice.

Methods: Seventy-five Balb/c mice were randomly divided into negative control group (n = 15), positive control group (n = 15), low MCP concentration group (n = 15), middle MCP concentration group (n = 15) and high MCP concentration group (n = 15). CT26 colon cancer cells were injected into the subcapsule of mouse spleen in positive control group, low, middle and high MCP concentrations groups, except in negative control, to set up a colon cancer liver metastasis model.
