Hepatitis B virus is mainly considered to cause hepatocellular carcinoma which is the fourth leading cause of cancer-related mortality worldwide. Treatment of Hepatitis B virus with nucleos(t)ide ...analogues can decrease the progression of the disease and subsequently decreases the incidence of hepatocellular carcinoma. In this review, we have discussed the different classes of nucleos(t)ide analogues used in the treatment of Hepatitis B virus and their relationship with the development of hepatocellular carcinoma. Furthermore, we discussed the effect of treatment of Hepatitis B virus with Nucleoside analogues (NAs) before, during and after surgery, chemoembolization, radiofrequency ablation, and chemotherapy for the treatment of hepatocellular carcinoma.
Acute porphyrias are a group of metabolic disorders resulting in defective porphyrin synthesis and reduced heme production, which carries a risk of malignancy. Porphyrias are inborn defects in the ...heme biosynthesis pathway resulting in neurovisceral manifestations and cutaneous photosensitivity attacks with multi-systemic involvement. Its estimated prevalence nears 5 per 100,000 patients worldwide. Subclinical liver disease is common, which can progress into transaminitis, fibrosis, cirrhosis, and malignancy. However, data on the incidence of primary liver cancer are lacking. We aim to determine the risk of hepatocellular carcinoma (HCC) in patients with porphyria. A systematic review and pooled analysis were conducted through 2021 on studies assessing blood tests, imaging, cancer development, liver transplant, surgical resection, and outcomes in porphyria. In total, 19 studies, which included 7381 patients with porphyria (3476 females), were considered for the final review. In eight studies, alpha-fetoprotein levels were elevated between 200 and 1000 IU/mL. Of the total cohort of patients with porphyria, primary liver cancer was diagnosed in 351 patients (4.8%), of whom 243 (3.3% of the total) were found to have HCC. A subset of patients was found to have cholangiocarcinoma (n = 18; 0.3% of the total). Interestingly, advanced liver disease or cirrhosis was not a prerequisite for the formation of HCC in a small group of patients. Of the total cohort, 30 patients underwent liver resection, 48 patients underwent liver transplantation, and 327 patients died. Patients with porphyria are at risk of developing primary liver malignancy. Further studies should aim to develop diagnostic and prognostic models aimed at the early detection of HCC in porphyria.
Although combination therapy is not recommended in patients with gastro-entero-pancreatic (GEP) neuroendocrine tumors (NETs), this strategy is widely used in clinical practice. This network ...meta-analysis of randomized trials evaluates targeted therapies and somatostatin analogues in GEP-advanced NETs, either alone or in combination, comparing the efficacy of different, single or combined treatment strategies in terms of progression-free survival (PFS). Interventions were grouped as analogs, everolimus, everolimus plus SSAs, sunitinib and placebo. In a secondary analysis, we also assessed the efficacy of individual-specific pharmacological treatments vs placebo or each other. From 83 studies identified, 8 randomized controlled trials were selected, with a total of 1849 patients with either functioning or non-functioning NETs. The analysis confirmed the superiority of all treatments over placebo (HR ranging from 0.34, 95% CI: 0.24-0.37 with the combination of everolimus plus SSAs to 0.42, 0.31-0.57 with the analogs; moderate quality of evidence). On ranking analysis, the combination of everolimus plus SSA (P score = 0.86) and then everolimus alone (P score = 0.65) ranked highest in increasing PFS. On comparative evaluation of different interventions, pasireotide (P score = 0.96) and everolimus + octreotide (P score = 0.82) ranked as the best pharmacological treatment options. Our findings support the use of combination therapy in the treatment of functioning and non-functioning GEP NETs. The role of pasireotide should be explored in selected subgroups of patients. Lastly, the combination of everolimus and octreotide appears promising and should be more widely considered in clinical practice.
Intermediate-stage hepatocellular carcinoma (BCLC B HCC) occurs in a heterogeneous group of patients and can be addressed with a wide spectrum of treatments. Consequently, survival significantly ...varies among patients. In recent years, several subclassification systems have been proposed to stratify patients' prognosis. We analyzed and compared these systems (Bolondi, Yamakado, Kinki, Wang, Lee, and Kim criteria) in patients undergoing systemic therapy.
We considered 171 patients with BCLC B HCC treated with sorafenib as first-line systemic therapy in six Italian centers from 2010 to 2021 and retrospectively applied the criteria of six different subclassification systems.
Except for the Yamakado criteria, all the subclassification systems showed a statistically significant correlation to overall survival (OS). In the postestimation analysis, the Bolondi criteria (OS of subgroups 22.5, 11.9, and 6.6 mo, respectively; C-index 0.586; AIC 1338; BIC 1344) and the Wang criteria (OS of subgroups 20.6, 11.9, and 7.0, respectively; C-index 0.607; AIC 1337; BIC 1344) presented the best accuracy. Further analyses of these two subclassification systems implemented with the prognostic factor of alpha-fetoprotein (AFP) > 400 ng/mL have shown an increase in accuracy for both systems (C-index 0.599 and 0.624, respectively).
Intermediate-stage subclassification systems maintain their predictive value also in the setting of systemic therapy. The Bolondi and Wang criteria showed the highest accuracy. AFP > 400 ng/mL enhances the performance of these systems.
We assessed the performance of direct-acting antivirals (DAAs) in hepatitis C virus (HCV)-infected people who use drugs (PWUDs) in terms of sustained virological response (SVR) and adherence rates in ...comparison to a location-matched cohort of non-PWUD HCV patients.
All consecutive HCV RNA-positive PWUDs were enrolled between 2015 and 2019. All subjects underwent DAA treatment according to international guidelines and then followed, at least, up to 12 weeks after the end of treatment (SVR12). The SVR and adherence to treatment was compared with that of non-PWUD HCV patients observed at hepatological units of the CLEO platform. Intention-to-treat analysis was performed.
A total of 1,786 PWUDs who were followed up were available for assessment. Most PWUDs (85.4%) were managed inside the specialized outpatient addiction clinics (SerDs). The overall SVR rate was 95.4%. The SerDs group achieved an SVR rate of 96.2% compared with 91.6% of the non-SerDs group (P < 0.001). Comparison with the non-SerDs group and the control HCV group showed a significant difference in the dropout rate (0.6% in the SerDs group versus 2.8% in the non-SerDs group and 1.2% in the control group; P < 0.001). At multivariate analysis, factors independently associated with SVR were use of the most recent regimens (elbasvir/grazoprevir, glecaprevir/pibrentasvir, and sofosbuvir/velpatasvir; odds ratio: 3.126; P = 0.000) and belonging to the SerDs group (odds ratio: 2.356; P = 0.002).
The performance of DAAs in PWUD is excellent, if 2 conditions are met: (i) that the latest generation drugs are used and (ii) that the patients are managed within the SerDs.
The aforementioned studies clearly highlight the importance of adjustment when analyzing long-term outcomes in patients with liver cirrhosis as the natural course of the disease can be influenced by ...several factors, even not strictly related to the underlying chronic viral infection 4. ...to date, there are no large scale trials directly comparing the 2 treatments for the management of chronic hepatitis B infection. ...we think other studies and large randomized controlled trials are needed to clarify this important issue; meanwhile, definitive assumptions on the superiority of 1 treatment over the other cannot be made.

Tenofovir treatment has lower risk of hepatocellular carcinoma than entecavir treatment in patients with chronic hepatitis B:asystematic review and meta-analysis.
Trans-arterial radio-embolization (TARE) is an emerging treatment for the management of hepatocellular carcinoma (HCC). TARE may compete with systemic chemotherapy, sorafenib, in intermediate stage ...patients with prior chemoembolization failure or advanced patients with tumoral macrovascular invasion with no extra-hepatic spread and good liver function. We performed a budget impact analysis (BIA) evaluating the expected changes in the expenditure for the Italian Healthcare Service within scenarios of increased utilization of TARE in place of sorafenib over the next five years.
Starting from patient level data from three oncology centres in Italy, a Markov model was developed to project on a lifetime horizon survivals and costs associated to matched cohorts of intermediate-advanced HCC patients treated with TARE or sorafenib. The initial model has been integrated with epidemiological data to perform a BIA comparing the current scenario with 20 and 80% utilization rates for TARE and sorafenib, respectively, with increasing utilization rates of TARE of 30, 40 and 50% over the next 1, 3 and 5 years.
Compared to the current scenario, progressively increasing utilization rates of TARE over sorafenib in the next 5 years is expected to save globally about 7 million Euros.
Radioembolization can be considered a valuable treatment option for patients with intermediate-advanced HCC. These findings enrich the evidence about the economic sustainability of TARE in comparison to standard systemic chemotherapy within the context of a national healthcare service.
Case-control observational studies suggested that aspirin might prevent hepatocellular carcinoma (HCC) in high-risk patients, even if randomized clinical trials are lacking. Information regarding ...aspirin in subjects who already developed HCC, especially in its advanced stage, are scarce. While aspirin might be a low-cost option to improve the prognosis, multiple confounders and safety concerns are to be considered. In our retrospective analyses of a prospective dataset (
= 699), after assessing the factors associated with aspirin prescription, we applied an inverse probability treatment weight analysis to address the prescription bias. Analyses of post-sorafenib survival were also performed to reduce the influence of subsequent medications. Among the study population, 133 (19%) patients were receiving aspirin at the time of sorafenib prescription. Aspirin users had a higher platelet count and a lower prevalence of esophageal varices, macrovascular invasion, and Child-Pugh B status. The benefit of aspirin was confirmed in terms of overall survival (HR 0.702, 95% CI 0.543-0.908), progression-free survival, disease control rate (58.6 vs. 49.5%,
< 0.001), and post-sorafenib survival even after weighting. Minor bleeding events were more frequent in the aspirin group. Aspirin use was associated with better outcomes, even after the correction for confounders. While safety concerns arguably remain a problem, prospective trials for patients at low risk of bleeding are warranted.
