MATERIAL AND METHODS This retrospective study included liver transplant recipients who received ICIs for recurrent hepatocellular carcinoma. During ICI therapy, baseline immunosuppressant doses were maintained, with low-dose steroid treatments added when clinically indicated. RESULTS A total of 25 patients were included, with 12 receiving ICIs as first-line therapy, and 13 as second-line therapy. The median progression-free survival (PFS) was 4.93 months (95% CI, 2.33-28.63) and 7.20 months (3.80-32.47), respectively. One patient (4.0%) developed grade 2 hepatitis, and 2 (8%) experienced grade 3 gastrointestinal bleeding. Concurrent steroid use was associated with fewer immune-related adverse events (0% vs 30%, P=0.052) but showed a trend toward shorter PFS (HR=2.30, P=0.071). Two patients (8%) achieved complete remission, and 4 (16%) maintained disease control for more than 1 year. In multivariable analysis, recurrence within 1 year after transplantation was the only significant prognostic factor for PFS (HR=2.98, P=0.043). CONCLUSIONS Our findings suggest that ICIs can be administered after liver transplantation without reducing baseline immunosuppressant doses, potentially minimizing the risk of fatal allograft rejection while still allowing antitumor activity.

This study aimed to construct and validate a machine learning-based nomogram for predicting the risk of severe PJP in KTRs using routine clinical indicators. MATERIAL AND METHODS A retrospective cohort of 169 KTRs diagnosed with PJP was analyzed. Severe PJP was defined as cases requiring intensive care unit (ICU) admission or death. The cohort was randomized into training (n=120) and testing (n=49) sets. Three machine learning algorithms (Boruta, RFE, and LASSO) were utilized for feature selection. A multivariate logistic regression model was established and visualized as a nomogram. Model performance was evaluated via area under the ROC curve (AUC), calibration plots, and decision curve analysis (DCA). Kaplan-Meier analysis was performed to assess risk stratification. RESULTS Four key predictors were identified: procalcitonin (PCT), (1→3)-ß-D-glucan (G_test), C-reactive protein (CRP), and the time from kidney transplantation to PJP onset (Time KT to PJP). Notably, shorter post-transplant time and elevated biomarkers were associated with greater severity. The nomogram demonstrated robust discrimination with AUCs of 0.935 (training) and 0.886 (testing), alongside excellent calibration. DCA confirmed a significant clinical net benefit. Furthermore, Kaplan-Meier analysis revealed that patients stratified as high-risk by the model had significantly lower survival rates compared to the low-risk group (P<0.0001).

Catorigization into dialysis (n=14) and non-dialysis (n=19) groups was based on early posttransplant dialysis requirement. SII, SIRI, and PIV were calculated from pretransplant laboratory parameters. Given the exploratory study design, analyses were primarily descriptive, supported by univariate comparisons and logistic regression with bootstrap resampling.

RESULTS The incidence of ICC among adult LT recipients was 0.4%. All cases were incidental findings in explanted livers. The mean ICC tumor size was 2.7±1.6 cm, and 22 patients had single ICC lesion.
