After oncologic resection, histological grading and staging of the tumor give important prognostic information about the future risk of recurrence and hence influence the subsequent management plan. Several studies and their meta-analysis have shown that various histological features (e.g., microscopic positive resection margins, plexitis, granuloma, mesenteric inflammatory activity) can predict postoperative clinical/endoscopic/surgical recurrence after resection in Crohn’s disease (CD). Inclusion of mesentery in surgical resection specimens has been shown to reduce surgical recurrence after ileocolonic resection in CD. However, there is no uniform histopathological staging system for risk stratification in postoperative CD to systematically predict postoperative recurrence. This is because the prediction to date is based on clinical characteristics (smoking status, disease phenotype, surgical history). Histopathological predictors are still not adopted in routine clinical practice due to the lack of a uniform staging system, heterogeneity of published studies and lack of standardized definition of histological features. In this article, we attempted to incorporate all such histological features in a single histological staging system CNM (Crohn’s primary site [resection margin positivity, plexitis, granuloma, depth of infiltration], nodes [presence of granuloma], mesentery [involved or not]) in surgical resection specimen in CD. The proposed CNM classification would help to enable systematic reporting, design future clinical trials, stratify postoperative recurrence risk and choose appropriate postoperative prophylaxis.

Background: s/Aims: Hepatocellular carcinoma (HCC) is generally diagnosed at an advanced stage, which limits curative treatment options for these patients. Locoregional therapy (LRT) is the standard approach to bridge and downstage unresectable HCC for liver transplantation (LT). Atezolizumab-bevacizumab (atezo-bev) can induce objective responses in nearly one-third of patients; however, the role and outcomes of downstaging using atezo-bev remains unknown. Methods: In this retrospective single-center study, we included consecutive patients between November 2020 and August 2023, who received atezo-bev with or without LRT and were subsequently considered for resection/LT after downstaging. Results: Of the 115 patients who received atezo-bev, 12 patients (10.4%) achieved complete or partial response and were willing to undergo LT; they (age, 58.5 years; women, 17%; Barcelona Clinic Liver Cancer stage system B/C, 5/7) had received 3-12 cycles of atezo- bev, and four of them had received prior LRT. Three patients died before LT, while three were awaiting LT. Six patients underwent curative therapies: four underwent living donor LT after a median of 79.5 days (range, 54-114) following the last atezo-bev dose, one underwent deceased donor LT 38 days after the last dose, and one underwent resection. All but one patient had complete pathologic response with no viable HCC. Three patients experienced wound healing complications, and one required re-exploration and succumbed to sepsis. After a median follow-up of 10 months (range, 4-30), none of the alive patients developed HCC recurrence or graft rejection. Conclusions Surgical therapy, including LT, is possible after atezo-bev therapy in well-selected patients after downstaging.
