Image Description
The post-chemotherapy tumors are evaluated for response and subdivided into 3 risk categories : low risk, intermediate risk, and high risk. This image shows a few residual nodules of blastema and scattered tubular elements. Post-chemotherapy specimens in which blastemal component constitutes more than 2/3 of the viable tumor are considered high risk tumors.
