oxaliplatin and raltitrexed treatment of colorectal cancer with liver metastases

Conditions: Colon Cancer Liver Metastasis

Summary: the purpose of this study was a randomized controlled trial to compare the effect of oxaliplatin and raltitrexed treatment of colorectal cancer with liver metastases by tace hepatic artery infusion

colorectal cancer is one of the most common malignancies, with 1 million new cases and half a million deaths each year worldwide. the development of metastases is the main cause of death. liver metastases are diagnosed in 10-25% of patients at the time of resection of their primary colorectal tumor and, eventually, up to 70% of patients with colorectal cancer develop liver metastases.oxaliplatin and raltitrexed were used for the treatment of colorectal cancer with liver metastases. we aimed to perform a randomized controlled trial to compare the effect of oxaliplatin and raltitrexed treatment of colorectal cancer with liver metastases by tace hepatic artery infusion.
