ABSTRACT
Objective To investigate the application of contrast-enhanced ultrasonograhy CEUS in the early assessment of antiangiogenic treatment in metastatic colorectal cancer Methods Among 41 colorectal cancer patients with liver metastases enrolled in this study 25 patients received treatment of antiangiogenic treatment bevacizumab combined with chemotherapy BV group and 16 patients received chemotherapy only non-BV group To assess the treatment responses in the liver lesions between and within these two groups CEUS scans were performed before the treatment T0 or??baseline on the day 2 T1 and on the day 7 T2 after the treatment The percentage differences were evaluated according to the CEUS quantitative parameters such as rise time RT peak intensity PI mean transit time MTT area under the curve AUC time from peak to one half TPH wash in slope WIS and time to peak TTP Results On T1 both the RT and MTT increased within the BV group and decrease within the non-BV group when compared with their own baselines the differences were statistically significant P 0 05 Conclusions CEUS can be used to assess the treatment response in liver metastatic patients with colorectal cancer by monitoring the change of the tumor perfusion before and after the treatment.
