Infarct-like Necrosis of the liver
A The response of colorectal adenocarcinoma liver metastases to perioperative chemotherapy can be assessed histologically in partial hepatectomy specimens. Necrosis in this scenario may represent a lack of treatment effect or a therapeutic response to chemotherapy. Use of Tumor regression grade (TRG) did not demonstrate a significant difference in disease-free and overall survival. An infarct-like necrosis (ILN) represents a form of treatment effect and should be distinguished from UN. A modified grading system that incorporates ILN may enhance the prognostic utility of TRG.
