[The evolution of the liver metastases from colorectal carcinoma treated with hepatic intra-arterial chemotherapy. The echographic and CT aspects].
The response of liver metastases to chemotherapy relies mainly on quantitative US and CT investigations, the two techniques being indifferently used. The morphologic changes of metastatic lesions during treatment have received little attention and their significance is still questionable. Based on the review of 53 US and 41 CT examinations of 15 patients treated with hepatic arterial chemotherapy for colorectal liver metastasis, our study was aimed at assessing: 1) the relationship between US and CT measurements of metastasis response to chemotherapy and 2) changes in the US and CT patterns of liver metastases during treatment and the existence of specific patterns of favorable response to chemotherapy or of disease progression. We concluded that: 1) as to quantitative response to chemotherapy, US and CT, performed on 13 patients within 1 month, were in agreement in all but 1 case, 2) US and CT patterns of treated liver metastases were different in case of favorable response and of disease progression; lesion outline, homogeneity and calcifications are useful diagnostic criteria to this purpose, 3) liver perfusion abnormalities may occur at various times during and after chemotherapy; these ischemic lesions must be differentiated from new metastases.
