This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e16 (https://www. gastrojournal.org/cme/home). Learning Objective: Upon completion of this CME activity, successful learners will be able to (1) identify key aspects of colonic endoscopic mucosal resection (EMR), (2) recognize the limitations of piecemeal resection, (3) explain how ablation of the post-EMR mucosal defect can mitigate those limitations, and (4) evaluate the future implications of these findings.

Aggressive Hodgkin's disease therapy is successful, but patients have a significant risk of second malignancy. Newer treatment programs focus on obtaining a relapse-free cure of Hodgkin's disease with judicious use of radiation and alkylating agent chemotherapy. Survivors of pediatric Hodgkin's disease require lifelong evaluation and cancer screening.
