[Changes in CT findings in patients with liver metastases of breast cancer during effective intra-arterial infusion].

A study was done of the changes occurring in the CT findings of 12 cases in which liver metastases were found after radical mastectomy for breast cancer, as a result of intermittent low-dose hepatic arterial infusion chemotherapy using a reservoir, achieving PR. In four cases (33.3%) only shrinkage of the metastatic lesions was seen; in 3 others (25.0%), this was accompanied by irregularities in the margins of the liver surface; in the other 5 (41.7%), a high proportion of total, widespread compensatory deformity of the liver was observed. A tendency was noted for these changes to be more pronounced in cases in which the metastatic lesions occupied a large proportion of the liver. Hepatic degeneration appeared with a high frequency in cases where liver metastasis followed breast cancer, and it is considered that considerable care is necessary in evaluating the efficacy of treatment.
