چکیده انگلیسی
To investigate the feasibility of contrast-enhanced ultrasound (CEUS) with perflubutane for evaluating anti-angiogenic effects, we assessed the contrast enhancement of mice xenograft treated with bevacizumab. SJSA-1 implanted mice were imaged before and 2, 6, 9 and 13 d after initiation of bevacizumab or saline treatment. Intra-tumoral perfusion areas were quantified by binarizing the ultrasound images and the micro-vessel density was observed by CD31 immunohistochemistry. As a result, the perfusion area and its ratio in the tumor were smaller in the bevacizumab group than the control group at 9 and 13 d, although tumor size was not significantly different. CD31-positive areas were smaller in the bevacizumab group than the control group and correlated well with the ratio of intra-tumoral perfusion areas. CEUS with perflubutane was found to have potential for early prediction of the anti-cancer activity of bevacizumab, and the perfusion area measured by binarized ultrasound images could be used as an indicator.
