Ultrasound Tumor Size Assessment, Histology and Serum Enzyme Analysis in a Rat Model of Colorectal Liver Cancer.

During tumor development, tissue necrosis appears as a natural phenomenon directly associated with an increase in tumor size. The aim of this study was to assess the use of ultrasound (US) for predicting natural tumor necrosis in a rat liver implant model of colorectal cancer. To achieve this goal, we sought to establish a correlation between US-measured tumor volume, serum enzyme levels and histopathological findings, particularly those regarding necrosis phenomena in liver implants.
