Reduced-Dose or Discontinuation of Bevacizumab Might Be Considered after Variceal Bleeding in Patients with Hepatocellular Carcinoma Receiving Atezolizumab/Bevacizumab: Case Reports.

Background and Objectives: Variceal bleeding (VB) is the most concerning condition that is difficult to treat after atezolizumab/bevacizumab in patients with advanced hepatocellular carcinoma (HCC). Materials and Methods: We would like to introduce the cases of two patients who underwent bevacizumab reduction or discontinuation when VB occurred after atezolizumab/bevacizumab. Results: VB occurred in two patients who showed good tumor response after atezolizumab/bevacizumab treatment, and all VBs were successfully treated with endoscopic variceal ligations. In the first patient, VB did not occur as the tumor response decreased after a 50% reduction in bevacizumab. In the second patient, VB occurred again after a 50% bevacizumab reduction, so bevacizumab was discontinued and treatment with atezolizumab alone has been successfully maintained. Conclusions: Accordingly, we would like to suggest that considering bevacizumab dose reduction instead of changing to tyrosine kinase inhibitor may be a good clinical choice in atezolizumab/bevacizumab patients who develop VB.

Addition of Kidney Dysfunction Type to MELD-Na for the Prediction of Survival in Cirrhotic Patients Awaiting Liver Transplantation in Comparison with MELD 3.0 with Albumin.

It is well known that renal dysfunction has a devastating effect on the prognosis of liver cirrhosis. In this study, the aim was to assess whether the incorporation of the kidney dysfunction type into the MELD-Na score enhances its predictive capacity for outcomes in patients awaiting liver transplantation (LT), compared to utilizing the MELD 3.0 score with albumin. In total, 2080 patients awaiting the LT were enrolled at two tertiary care institutions in Korea. Discrimination abilities were analyzed by using Harrell's c-index and iAUC values between MELD-Na-kidney dysfunction type (MELD-Na-KT) and MELD 3.0 with albumin. Clinical endpoints encompassed 3-month survival, 3-month transplant-free survival (TFS), overall survival (OS), and total TFS. Out of the total of 2080 individuals, 669 (32.16%) were male. Regarding the types of renal function impairment, 1614 (77.6%) were in the normal group, 112 (5.38%) in the AKD group, 320 (15.35%) in the CKD group, and 34 (1.63%) were in the AKD on CKD group. MELD 3.0 with albumin showed better discrimination (c-index = 0.714) compared to MELD-Na-KT (c-index = 0.708) in predicting 3-month survival. Similar results were observed for OS, 3-month TFS, and total TFS as well. When divided by sex, MELD 3.0 with albumin showed the comparable prediction of 3-month survival to MELD-Na-KT (c-index 0.675 vs. 0.671, p-value 0.221) in males. However, in the female group, MELD 3.0 with albumin demonstrated better results compared to MELD-Na-KT (c-index 0.733 vs. 0.723, p-value 0.001). The integration of kidney dysfunction types into the MELD-Na did not yield superior prognostic results compared to the MELD 3.0 score with albumin. Rather, in the female group, the MELD 3.0 score with albumin was better able to predict survival. These findings suggest that laboratory values pertaining to liver dysfunction or creatinine levels may be more significant than the type of kidney dysfunction when predicting the short-term prognosis of LT candidates.
