About
The SEGWAY trial is a prospective, single-arm clinical study to evaluate the efficacy and safety of flow diversion to protect non-tumorous liver function using short-acting gelatin sponge particles during Yttrium-90 radioembolization of liver cancer.
Full description
Short-acting gelatin sponge particles will be used during radioembolization to protect normal liver tissue in patients with liver cancer whose treatment field encompasses a substantial portion of non-tumorous liver tissue. Recanalization of the embolized hepatic artery will be assessed by angiography within 30 minutes following the procedure. Suppression of Y90 microsphere delivery to the protected, non-tumorous liver tissue will be evaluated using Y90 PET-CT imaging, by comparing the protected regions to non-protected, non-tumorous regions within the perfused area. Enhanced tumor uptake of Y90 microspheres will be quantified using the tumor-to-normal liver ratio (TNR), calculated by comparing pre-procedure SPECT-CT with post-procedure PET-CT data. Finally, preservation of liver function in protected tissue relative to unprotected tissue will be assessed six months post-procedure using signal intensity ratios on hepatobiliary phase images obtained from gadoxetic acid-enhanced MRI.
