[A case of renal pelvic cancer with hepatic metastasis where hepatic arterial infusion chemotherapy (HAIC) proved effective: a case report].

The patient was a 60 year-old male who first visited a doctor because of back pain on the right side in May 2003. As a result of thorough examination, he was diagnosed with right renal pelvic cancer (cT4, N2, M1), and was referred to our department for treatment. In spite of systemic chemotherapy and radiation therapy in combination with cisplatinum on the primary tumor were performed from May 2003 to December 2005, the number and size of hepatic metastases increased. Consequently, considering hepatic metastasis as the specific prognosis factor, the patient was given a total of 14 cycles of hepatic arterial infusion chemotherapy (HAIC) from January to October 2006. As a result, the hepatic metastases completely disappeared. Then HAIC was tentatively discontinued and the patient was followed up. However, as new lung metastases were found by CT in March 2007, radiation therapy was performed on the lung metastases. As hepatic metastasis was recognized again by CT in April 2007, HAIC was resumed and the patient was given a total of 6 cycles starting from May 2007. During that period, two transurethral resection of bladder tumor were performed against the recurrence within the bladder while transarterial embolization was performed against the bleeding in the right kidney. The patient was regarded as a long-term survivor surviving for about five years after his initial consultation.
