It is well-known that the patients with pancreatic cancer are vulnerable for recurrence such as local relapse and liver metastasis after surgical resection. We revealed that a patient with local relapse without liver metastasis showed better prognosis as compared with a patient having liver metastasis. We usually adapt further therapeutic intervention for local recurrence using external radiation therapy accompanied with 5FU infusion as a radiosensitizer, if the patient is not revealed with liver metastasis. On the other hand, there is no effective intervention for liver metastasis accompanying pancreatic cancer, as small lesions of multiple liver metastases progress rapidly. We insert the tip of catheter in proper hepatic artery in order to infuse MMC once a week at outpatient clinic. However, we were not yet able to evaluate the effect of arterial infusion therapy.
