Purpose: To determine if the pattern of retained contrast on immediate postprocedure computed tomography (CT) after particle embolization of hepatic tumors predicts modified Response Evaluation Criteria in Solid Tumors (mRECIST) response.
Materials And Methods: This study was approved by the Institutional Review Board with a waiver of authorization. One hundred four liver tumors were embolized with spherical embolic agents (Embospheres, Bead Block, LC Bead) and polyvinyl alcohol.
Article Synopsis
- The study evaluated how tissue analysis from electrodes used in liver tumor radiofrequency ablation (RFA) predicts local progression-free survival (LPFS) and overall survival (OS).
- Out of 68 liver tumors treated, 55 showed complete ablation while 13 had remaining viable cells, with viable tumors linked to much worse LPFS and OS rates.
- The presence of Ki-67-positive tumor cells on electrodes emerged as a strong indicator of poor patient outcomes, overriding tumor size as a significant risk factor over time.
Background: The objective of this study was to examine the current treatment for liver abscess and to assess the factors associated with failure of percutaneous drainage.
Study Design: Records of 58 patients with pyogenic hepatic abscess, from 1998 to 2009, were examined. Clinicopathologic variables were analyzed as predictors of failure of percutaneous drainage using multivariable logistic regression.
