Indications for liver transplantation for hepatocellular carcinoma are evolving and so-called expanded criteria remain debated. Locoregional therapies are able to downstage hepatocellular carcinoma from beyond to within the Milan criteria. We aimed to investigate the efficacy of liver transplantation after successful hepatocellular carcinoma downstaging. We did an open-label, multicentre, randomised, controlled trial designed in two phases, 2b and 3, at nine Italian tertiary care and transplantation centres. Patients aged 18–65 years with hepatocellular carcinoma beyond the Milan criteria, absence of macrovascular invasion or extrahepatic spread, 5-year estimated post-transplantation survival of at least 50%, and good liver function (Child-Pugh A-B7) were recruited and underwent tumour downstaging with locoregional, surgical, or systemic therapies according to multidisciplinary decision. After an observation period of 3 months, during which sorafenib was allowed, patients with partial or complete responses according to modified Response Evaluation Criteria in Solid Tumors were randomly assigned (1:1) by an interactive web-response system to liver transplantation or non-transplantation therapies (control group). A block randomisation (block size of 2), stratified by centre and compliance to sorafenib treatment, was applied. Liver transplantation was done with whole or split organs procured from brain-dead donors. The control group received sequences of locoregional and systemic treatment at the time of demonstrated tumour progression. The primary outcomes were 5-year tumour event-free survival for phase 2b and overall survival for phase 3. Analyses were by intention to treat. Organ allocation policy changed during the course of the study and restricted patient accrual to 4 years. This trial is registered with ClinicalTrials.gov, NCT01387503. Between March 1, 2011, and March 31, 2015, 74 patients were enrolled. Median duration of downstaging was 6 months (IQR 4–11). 29 patients dropped out before randomisation and 45 were randomly assigned: 23 to the transplantation group versus 22 to the control group. At data cutoff on July 31, 2019, median follow-up was 71 months (IQR 60–85). 5-year tumour event-free survival was 76·8% (95% CI 60·8–96·9) in the transplantation group versus 18·3% (7·1–47·0) in the control group (hazard ratio [HR] 0·20, 95% CI 0·07–0·57; p=0·003). 5-year overall survival was 77·5% (95% CI 61·9–97·1) in the transplantation group versus 31·2% (16·6–58·5) in the control group (HR 0·32, 95% CI 0·11–0·92; p=0·035). The most common registered grade 3–4 serious adverse events were hepatitis C virus recurrence (three [13%] of 23 patients) and acute transplant rejection (two [9%]) in the transplantation group, and post-embolisation syndrome (two [9%] of 22 patients) in the control group. Treatment-related deaths occurred in four patients: two (8%) of 23 patients in the transplantation group (myocardial infarction and multi-organ failure) versus two (9%) of 22 patients in the control group (liver decompensation). Although results must be interpreted with caution owing to the early closing of the trial, after effective and sustained downstaging of eligible hepatocellular carcinomas beyond the Milan criteria, liver transplantation improved tumour event-free survival and overall survival compared with non-transplantation therapies Post-downstaging tumour response could contribute to the expansion of hepatocellular carcinoma transplantation criteria.

The clinical usefulness of alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC) management is debatable. To assess, in a large multi-centric survey, diagnostic and prognostic reliability of AFP, predictive factors, and any correlation with the tumor immunophenotype. A total of 1,158 patients with HCC were analyzed with reference to serum AFP levels at diagnosis. We evaluated: HCC grading, histotype, and size; Okuda, tumor-nodes-metastases (TNM), and Child-Pugh scores; liver function, symptoms, presence of metastases or portal thrombosis, etiology, survival, and treatment. In 66 patients with histological diagnosis, the pathologists evaluated p53 overexpression, MIB 1 labeling index, BCL-2 positive cells (index of apoptosis), and CD44 (adhesion molecule) positivity. Patients were divided into three AFP groups: normal (<20 ng/mL) [46%], elevated (21-400 ng/mL) [36%], and diagnostic (>400 ng/mL) [18%]. Statistical correlations were significant for: weight loss (p= 0.0056), pain (p= 0.0025), Child-Pugh score (p= 0.001), tumor size, Okuda's and TNM stages, metastases, thrombosis, type of treatment (all p < 0.0001), and female sex (p < 0.004). AFP correlated with survival overall, in patients untreated, transplanted, or undergoing locoregional treatments; but not in those surgically treated. In the discriminant analysis, the related variables were size, female sex, Child-Pugh score, TNM staging (steps 1-4). When using the receiver operating characteristic curve, the prognostic reliability of AFP was limited with area under the curve of 0.59. Finally, patients with low expression of BCL2 had high AFP levels (p < 0.05). AFP positively correlated with Edmonson score (p < 0.0001). The evaluation of this large series of HCC patients allowed us to: confirm the low sensitivity (54%) of AFP in the diagnosis of HCC and its prognostic value, albeit limited, being tumor size, female sex (intriguingly enough), Child-Pugh score, and TNM staging independent predictors.

Introduction Lenvatinib is approved for the treatment of patients with metastatic or recurrent hepatocellular carcinoma (HCC); however, clinical outcomes of lenvatinib therapy in patients with post‐liver transplantation (LT) HCC recurrence remain unclear. We investigated the efficacy and safety of lenvatinib in patients with post‐LT HCC recurrence. Methods This multinational, multicenter, retrospective study included 45 patients with recurrent HCC after LT who received lenvatinib at six institutions in three countries (Korea, Italy, and Hong Kong) from June 2017 to October 2021. Results At the time of lenvatinib initiation, 95.6% (n = 43) of patients had Child–Pugh A status, and 35 (77.8%) and 10 (22.2%) participants were classified as having albumin–bilirubin (ALBI) grades 1 and 2, respectively. The objective response rate was 20.0%. With a median follow‐up duration of 12.9 months (95% confidence interval [CI]: 11.2–14.7), the median progression‐free survival and overall survival (OS) were 7.6 (95% CI: 5.3–9.8) months, and 14.5 (95% CI: 0.8–28.2) months, respectively. Patients with ALBI grade 1 showed significantly better OS (52.3 months, [95% CI: not assessable]) than patients with ALBI grade 2 (11.1 months [95% CI: 0.0–30.4 months], p = 0.003). The most common adverse events were hypertension (n = 25, 55.6%), fatigue (n = 17, 37.8%), and anorexia (n = 14, 31.1%). Conclusion Lenvatinib showed consistent efficacy and toxicity profiles in patients with post‐LT HCC recurrence that were comparable to those reported from previous studies among non‐LT HCC patients. The baseline ALBI grade correlated with better OS in post‐LT lenvatinib‐treated patients. Lenvatinib showed consistent efficacy and toxicity profiles in patients with post‐LT HCC recurrence that were comparable to those reported from previous studies among non‐LT HCC patients. The baseline ALBI grade correlated with better OS in post‐LT lenvatinib‐treated patients.

Small molecule protein kinase inhibitors (PKIs) have become an effective strategy for cancer patients. However, hepatotoxicity is a major safety concern of these drugs, since the majority are reported to increase transaminases, and few of them (Idelalisib, Lapatinib, Pazopanib, Pexidartinib, Ponatinib, Regorafenib, Sunitinib) have a boxed label warning. The exact rate of PKI-induced hepatoxicity is not well defined due to the fact that the majority of data arise from pre-registration or registration trials on fairly selected patients, and the post-marketing data are often based only on the most severe described cases, whereas most real practice studies do not include drug-related hepatotoxicity as an end point. Although these side effects are usually reversible by dose adjustment or therapy suspension, or by switching to an alternative PKI, and fatality is uncommon, all patients undergoing PKIs should be carefully pre-evaluated and monitored. The management of this complication requires an individually tailored reappraisal of the risk/benefit ratio, especially in patients who are responding to therapy. This review reports the currently available data on the risk and management of hepatotoxicity of all the approved PKIs.

Background and Aim: Hepatocellular carcinoma (HCC) recurrence rates after liver transplantation (LT) range between 8 and 20%. Alpha-fetoprotein (AFP) levels at transplant can predict HCC recurrence, however a defined cut-off value is needed to better stratify patients. The aim of this study was to evaluate the rate of HCC recurrence at our centre and to identify predictors, focusing on AFP. Methods: We retrospectively analysed 236 consecutive patients that were waitlisted for HCC who all met the Milan criteria from January 2001 to December 2017 at our liver transplant centre. A total of twenty-nine patients dropped out while they were waitlisted, and 207 patients were included in the final analysis. All survival analyses included the competing-risk model. Results: The mean age was 56.8 ± 6.8 years. A total of 14% were female (n = 29/207). The median MELD (model for end-stage liver disease) at LT was 12 (9–16). The median time on the waitlist was 92 (41–170) days. The HCC recurrence rate was 16.4% (n = 34/208). The mean time to recurrence was 3.3 ± 2.8 years. The median AFP levels at transplant were higher in patients with HCC recurrence (p < 0.001). At multivariate analysis, the AFP value at transplant that was greater than 25.5 ng/mL (AUC 0.69) was a strong predictor of HCC recurrence after LT [sHR 3.3 (1.6–6.81); p = 0.001]. The HCC cumulative incidence function (CIF) of recurrence at 10 years from LT was significantly higher in patients with AFP > 25.5 ng/mL [34.3% vs. 11.5% (p = 0.001)]. Moreover, an increase in AFP > 20.8%, was significantly associated with HCC recurrence (p = 0.034). Conclusions: In conclusion, in our retrospective study, the AFP level at transplant > 25.5 ng/mL and its increase greater than 20.8% on the waitlist were strong predictors of HCC recurrence after LT in a cohort of patients that were waitlisted within the Milan criteria. However further studies are needed to validate these data.

The aim was to evaluate cost-effectiveness of yttrium-90 transarterial radioembolization (TARE) in comparison to sorafenib treatment. A single-center, retrospective, observational study was performed, 166 patients with intermediate-/advanced-stage hepatocellular carcinoma were treated with sorafenib and 19 with TARE. The patients out of the sorafenib group matching the inclusion criteria for TARE, were reassigned to a subgroup SOR3. Mean costs for SOR3 patients amounted to €27,992 per patient, instead for TARE treatment, mean expense per patient was €17,761 (p = 0.028). Overall survival was similar between the two groups, while midterm survival rates (p = 0.012) were significantly higher with TARE treatment. TARE causes significantly lower treatment costs than sorafenib with better outcome in midterm survival.

Background: Clinical phenotypes of small and large hepatocellular carcinomas (HCCs) are not well characterized. Aim: To evaluate the characteristics of small HCCs diagnosed by screening. Method: A cohort of 430 small HCCs that were diagnosed through screening, were dichotomized according to a size of ≤3 cm or >3 cm maximum tumor diameter and compared for radiological and blood-test parameters. Results: There were 330 males and 100 females. A higher percent of females had smaller tumors. The majority of patients had single tumors, but 15% of those with larger tumors had portal vein thrombosis (PVT) compared to 5% of those with smaller tumors. Significant differences between the tumor-size groups included alpha-fetoprotein (AFP) values and platelet counts, with thrombocytopenia and elevated bilirubin levels being associated with smaller tumors. In comparing PVT-positive and PVT-negative patients, AFP levels and platelet counts were also significantly different between the 2 groups. A mean multinomial multiple logistic regression model was developed for maximum tumor diameter plus PVT. Conclusions: The finding of larger tumors being associated with normal platelets and bilirubin levels in comparison to smaller tumors having thrombocytopenia reveals 2 different patterns of HCC presentation.

Sorafenib (Nexavar ® , Bayer), a multi-targeted tyrosine kinase inhibitor, was the first systemic agent that demonstrated a significant improvement in the overall survival in patients with advanced hepatocellular carcinoma and well-preserved liver function. This drug is now recommended in patients with advanced hepatocellular carcinoma as first-line therapy and for patients not suitable for locoregional treatment. This brief article, produced by a multidisciplinary panel including specialists in gastroenterology and oncology, provides an overview of the major issues related to systemic treatment of hepatocellular carcinoma with sorafenib, including staging and prognostic strategies, assessment of liver disease and its complications, and efficacy and safety of this molecule. Particular emphasis is given on how to improve tolerability of sorafenib in difficult-to-treat patients.

Background Survival in HCC depends on diagnosis at early tumor stage, best achieved through surveillance radiology. There is also a need for complementary serum tests. Methods We evaluated baseline liver function parameters from a cohort of 231 HCC patients who were diagnosed by surveillance. They were ordered according to their tumor mass and trends in the data were analyzed. Results Trends in serum GGTP levels increased linearly with increases in small tumor mass, but the patterns for AFP levels were more complex and elevated only with larger tumor mass. ALKP levels were elevated in association with small tumors and further increased with increasing tumor mass. The relationships of serum AFP to GGTP, of albumin to bilirubin and of ALKP to bilirubin, helped identify tumor mass phenotypes. There was an especially important relationship between serum bilirubin and AFP, suggesting that HCC growth and liver factors were interdependent. Conclusions Small HCCs demonstrated several phenotypic sub-groups, with serum GGTP and ALKP increasing and albumin decreasing in many patients with increasing tumor mass.
