[A case of recurrent pelvic tumor of sigmoid colon cancer showing partial response to lipiodolization]

Abstract

We performed lipiodolization and immunochemotherapy for recurrent pelvic tumor of sigmoid colon cancer using an infuserport which was implanted and connected to the catheter placed in the right internal iliac artery. Following lipiodolization, the level of CEA (980 ng/ml) decreased to within the normal range. MRI showed necrotic change and regression (more than 50%) of tumor. DSA revealed disappearance of tumor neovascularity. No serious side effect but skin erosion in the gluteal region was encountered after lipiodolization. This result suggests that lipiodolization is worth performing in further clinical trials for pelvic tumor.
