Several randomized clinical trials comparing different bowel preparations (BP) have shown similar efficacy; however, there is a lack of real-world studies on this topic. This study aims to identify the most effective BP regimen in a real-world setting and any predictors of inadequate BP. A retrospective single-center study was conducted over 14 months at an academic hospital including outpatient colonoscopies in which adult patients did not teach on how to perform BP before colonoscopy. Colonoscopies with 1L-PEG, 2L-PEG and picosulphate mixtures were considered. A multivariable analysis for factors associated to poor BP was fitted. Overall, 1779 patients (51 %F, 60±14) years were included. The 1L-PEG regimen provided a higher rate of BP adequacy at multivariate analysis (adjusted OR 2.30, 95 %CI 1.67-3.16,p < 0.001) and was associated with higher median Boston Bowel Preparation Scale score (p < 0.001), higher rate of right-colon cleansing (p < 0.001) and exam completion (p = 0.04). Furthermore, we identified male sex, history of constipation, active smoking, previous pelvic surgery, concomitant psychiatric/neurological or chronic kidney diseases as predictors of inadequate BP. This is the largest real-world study comparing 1L-PEG to other BP regimens. Our results suggest 1L-PEG provides better BP in a non-controlled setting, improving clinical practice quality and minimizing the need for repeated colonoscopies and saving healthcare resources.

Background: The Barcelona Clinic Liver Cancer (BCLC) system for HCC was updated in 2022. The aim of the study was to assess the suitability and impact on overall survival (OS) of BCLC_2022, along with “clinical decision-making” (CDM), using BCLC_2018 as a benchmark. Methods: We retrospectively evaluated 798 patients with de novo HCC followed prospectively from 2006 to 2022: 187 in BCLC 0, 371 in A, 132 in B, 87 in C, and 21 in D, all managed by a multidisciplinary team. Patients were followed until death or at the end of the follow-up period in December 2022. Results: The suitability of the algorithm increased from 51% for BCLC_2018 to 69% for BCLC_2022 (p<0.001). Among those treated with the newly introduced “lower priority options,” 22% were in BCLC 0 and 37% in A, showing lower rates of complete response (CR) and shorter OS compared to first-line treatments. In BCLC 0 and A, CDM was associated with a significant decrease in “downward stage migration” with BCLC_2022 (from 33% to 16%, p<0.001). Conversely, in BCLC B and C, “upward stage migration” correlated with higher CR rates and longer OS [63 (36–72) vs. 28 (18–44) months, p=0.003 in BCLC B; 21 (15–44) vs. 11 (4–25) months, p200 ng/mL, Child–Pugh score C, advanced BCLC stage, and noncurative treatment. Conclusions: BCLC_2022 and CDM provide greater flexibility in clinical practice without adversely affecting patient survival. Access to curative treatments improves the outcomes of selected patients in all stages.

Background and aims: Liver transplantation is effective against hepatocellular carcinoma (HCC), but recurrence remains a challenge. Traditional criteria based on tumor size, nodule number, and AFP levels have had limited success in predicting aggressiveness. [18F]FDG PET/CT has shown promise in identifying high-risk tumor features, including microvascular invasion (MVI), which is a key predictor of recurrence. Methods: In this retrospective, single-center study, all consecutive patients who underwent LT for HCC between 2010 and 2019 were included. Prior to listing, the patients underwent [18F]FDG PET/CT, and explant pathology was analyzed for MVI and other histological features. The primary objective was to identify the predictors of early HCC recurrence (within 24 months after LT). Secondary objectives included identifying predictors of high-risk histological features of the explant, describing recurrence patterns, and assessing post-recurrence survival. Results: The study included 143 patients (median age 59 years [IQR 54–64], 85% males, median MELD 10 [IQR 8–14], median AFP value 8.5 [IQR 4–39] ng/mL) and 40 (28%) with intra-hepatic [18F]FDG PET/CT positivity. HCC recurred post-LT in 25 patients (17%) (median post-LT follow-up 49 months [IQR 28.5–77]) and within 24 months in 12 patients (48%). MVI at the explant stage was independently associated with early recurrence (HR: 7.20, 95% CI 1.82–28.45, p = 0.005), while intra-hepatic [18F]FDG PET/CT positivity before LT independently predicted MVI in explants (OR 3.90, 95% CI 1.30–11.71, p = 0.01). Conclusions: [18F]FDG PET/CT may offer a valuable tool for pre-transplant risk assessment by identifying MVI, which is an independent predictor of early cancer recurrence. Its incorporation into the selection criteria for LT may enhance patient stratification and post-transplant outcomes.

Background and aims: Hepatocellular carcinoma (HCC) patients frequently present with comorbidities that limit therapeutic options and increase mortality. This study evaluated the performance of the Charlson Comorbidity Index (CCI) and a modified CCI (mCCI) in stratifying patients with HCC to predict treatment allocation and survival. Methods: A retrospective single-center cohort study analyzed 401 patients with de novo HCC (74% male, median age 68 years, 80% Child–Pugh-Turcotte (CPT) A, 65% viral etiology, 70% Barcelona Clinic Liver Cancer stage (BCLC) 0/A). CCI and mCCI (with points related to HCC and chronic liver disease excluded), were calculated at diagnosis for each patient. The primary endpoint was overall survival (OS) estimated by Kaplan–Meier method and compared across mCCI classes; Cox uni/multivariable models were applied to identify predictors of mortality. The secondary aim was evaluating the association between mCCI and treatment allocation. Results: While CCI classified 94% of patients as “high-risk”, mCCI reclassified patients into “high-risk” (21%), “intermediate-risk” (48%), and “low-risk” (31%), demonstrating better stratification whilst maintaining a strong correlation with CCI (Kendall’s tau-b = 0.57, p < 0.001). BCLC B patients with “high-risk” mCCI exhibited significantly lower access to first-line curative treatment (14% vs. 47%, p = 0.03). Moreover, “high” or “intermediate-risk” patients according to mCCI experienced significantly shorter OS compared to “low-risk” (median OS 36 vs. 49 vs. 74 months, p < 0.001). “High-risk” and “intermediate-risk” mCCI classes were independent predictors of mortality, alongside alpha-fetoprotein, CPT and BCLC stage. Considering the items composing mCCI, age and cardiovascular diseases were independent predictors of mortality. Conclusions: mCCI provides a more accurate assessment of comorbidities than the standard CCI and is associated with survival, hence it can contribute to designing patient-tailored therapeutic strategies.

Background and Aims: Accuracy of Baveno criteria for avoiding endoscopy in patients with hepatocellular carcinoma (HCC) is uncertain, and systematic upper gastrointestinal endoscopy (UGE) may not be necessary. We evaluated Baveno VI criteria performance in this population and developed an alternative non-invasive rule to exclude esophagogastric varices of any grade, rather than high-risk varices (HRV). Methods: Patients with BCLC 0-C HCC and compensated advanced chronic liver disease (cACLD) from Italian Liver Cancer (ITA.LI.CA) database, with available liver stiffness measurement (LSM), UGE, and blood tests within six months of diagnosis, were included. Independent predictors of varices identified by logistic regression were combined through grid-search to derive a rule-out strategy (SAPHE-R), validated by bootstrap-resampling and in an independent cohort (Vienna). Results: The derivation cohort comprised 598 patients (age, 69 years; male sex, 75.3%; viral etiology, 69.3%; BCLC 0/A, 77.9%; ALBI 1, 54.2%; varices, 33.4%; HRV, 11.2%). Baveno VI criteria missed 8.5% of varices and 6.0% of HRV, sparing 31.1% of UGE. Independent predictors of varices were incorporated into SAPHE-R (LSM≤16 kPa, platelet count ≥160×10⁹/L, ALBI grade 1), which missed 4.0% of varices (HRV 3.0%, spared UGE 17.6%). In the validation cohort (n=149), SAPHE-R missed 4.8% of varices (HRV 3.1%, spared UGE 14.8%). Results remained consistent in sensitivity analyses. In an exploratory analysis, no HVPG-defined CSPH was observed among SAPHE-R rule-out patients (0/22). Conclusions: Baveno VI criteria showed suboptimal performance in patients with HCC and cACLD, whereas SAPHE-R provided a reliable non-invasive strategy to rule out varices, facilitating variceal risk assessment in patients with HCC.
