[A case of multiple liver metastases of breast cancer treated successfully with high-dose intraarterial chemotherapy under hepatic venous isolation and charcoal hemoperfusion (HVI-CHP)].

The patient was a 53-year-old woman who underwent a standard radical mastectomy for right breast cancer five years ago and was recently referred to our hospital with a complaint of abdominal fullness. Systemic chemotherapy (CMFS) was performed based on the diagnosis of multiple liver metastases of the breast cancer, but its effect was unsatisfactory. In this case, we gave her high-dose intraarterial chemotherapy under HVI.CHP for metastatic liver tumors. Although slight elevation of serum GOT and GPT levels and leucopenia (1,800/mm3) were observed, alopecia did not occur throughout the posttreatment course. The levels of tumor markers including CEA, NCC-ST439 and CA15-3 showed remarkable reductions; CEA (ng/ml): 18.4-->3.0, NCC-ST439 (U/ml): 33.0-->2.4, CA15-3(U/ml): 137.9-->26.3. Abdominal CT scan after the treatment demonstrated remarkable regression of liver metastases, showing a partial response (volume reduction: 61%). In conclusion, HVI.CHP achieved a significant reduction in systemic drug exposure and allowed dose intensification of adriamycin during intraarterial chemotherapy. Therefore, we consider that high-dose intraarterial chemotherapy under HVI.CHP offers an effective therapeutic option for multiple liver metastases of the breast cancer.
