Abstract
During the last several years Transcatheter arterial chemoembolization (TACE) is world wide used in treatment of patients with Hepatocellular carcinoma (HCC). Very limited data are available about the results of this technique in patients with other malignant liver tumors including metastasis. Many investigators have reported their results of tumors treated with TACE, usually using cross-sectional imaging(ultrasonography, CT, or MR imaging) to measure tumor size before and after therapy and using the World Health Organization criteria of tumor size to determine the ”response” rate. By these criteria complete response indicates complete disappearance of the lesion; partial response means reduction of size of more than 50%; minor response means reduction of 25-50%; and no change means less than 25% increase or decrease in tumor size.Progressive disease indicates more than 25% increase in tumor size.Other investigators have proposed using tumor necrosis, rather than size, as the criterion to judge response to TACE, while others have proposed judging therapeutic response by angiographic demonstration of decreased or absent tumor vessels and by appearance of new lesions. In this study 100 patients with different groups of malignant liver tumors were treated by TACE. These patients have had biphasic spiral CT before the first session of chemoembolization and as a follow up examination for three cycles of emholization treatment. All patients on our study had pathological proof of malignant liver tumor before initiation of treatment. None of our patients had received any form of treatment beside TACE.
