Visualization of Anti-angiogenic Effects With Perfusion Computed Tomography (CTP) (AVA-CTP)
Visualization of Anti-angiogenic Effects With Perfusion Computed Tomography (CTP) in mCRC Patients Treated With First-line Bevacizumab
연구 개요
상세 설명
So far, CTP has provided non-invasive imaging of tumor biological response to anti-angiogenic and vascular targeting agents in a number of clinical trials with increasing clinical application. CTP can be examined with a variety of commercially available CE-certified CT scanners and imaging post-processing is possible with commercially available CE-certified software from different vendors, too. In several studies, anti-angiogenic effects have been detected with CTP but further evidence for its clinical validation has to be proven in clinical trials.
Changes in tumor vasculature measured by CTP will be correlated to the clinical efficacy parameters progression-free survival, overall survival and response rate, thus identifying a group of patients who profit most from the anti-angiogenic treatment.
