Background: COVID-19 pandemic has profoundly changed the activities and daily clinical scenarios, subverting organizational requirements of our Gastroenterology Units. AIM: to evaluate the clinical needs and outcomes of the gastroenterological ward metamorphosis during the COVID-19 outbreaks in a high incidence scenario. Methods: we compared the pertinence of gastroenterological hospitalization, modality of access, mortality rate, days of hospitalization, diagnostic and interventional procedures, age, Charlson comorbidity index, and frequency of SARS-CoV-2 infections in patients and healthcare personnel across the first and the second COVID-19 outbreaks in a COVID-free gastroenterological ward in the metropolitan area of Milan, that was hit first and hardest during the first COVID-19 outbreak since March 2020. Results: pertinence of gastroenterological hospitalization decreased both during the first and, to a lesser degree, the second SARS-CoV2 waves as compared to the pre-COVID era (43.6, 85.4, and 96.2%, respectively), as occurred to the admissions from domicile, while age, comorbidities, length of stay and mortality increased. Endoscopic and interventional radiology procedures declined only during the first wave. Hospitalized patients resulted positive to a SARS-CoV-2 nasopharyngeal swab in 10.2% of cases during the first COVID-19 outbreak after a median of 7 days since admission (range 1–15 days) and only 1 out of 318 patients during the second wave (6 days after admission). During the first wave, 19.5% of healthcare workers tested positive for SARS-CoV-2. Conclusions: a sudden metamorphosis of the gastroenterological ward was observed during the first COVID-19 outbreak with a marked reduction in the gastroenterological pertinence at the admission, together with an increase in patients' age and multidisciplinary complexity, hospital stays, and mortality, and a substantial risk of developing a SARS-CoV-2 test positivity. This lesson paved the way for the efficiency of hospital safety protocols and admission management, which contributed to the improved outcomes recorded during the second COVID-19 wave.

Simple Summary: Multimodality treatment can improve outcome of malignant pleural mesothelioma (MPM) patients. However, the ideal scheme of combination of them is still unknown. We analyzed a case series of 17 patients treated at our institution with a sequence of induction chemotherapy, surgery, adjuvant radiotherapy and chemotherapy. Median overall survival was 32.1 months, median progression free survival was 23.7 months with a safe profile. These data according to our experience represent a great example of feasibility in clinical practice of three-modality four step approach and encourage further prospective studies to better define the details of treatment. Background: Multimodality treatment is considered the best treatment strategy for malignant pleural mesothelioma (MPM). However, the ideal combination of them is still a matter of controversy. Here, we report a case series of MPM treated with a trimodality approach: induction chemotherapy (CT), pleurectomy/decortication (P/D), postoperative radiotherapy (RT) and post-operative CT. Methods: A retrospective case series of 17 MPM patients treated between 2013 and 2020 is presented. Patients had epithelial or mixed MPM diagnosed by video-assisted thoracoscopy and pathologic IMIG stage I or II disease. Treatment details and radiological data were collected. Induction therapy consisted of combination of cisplatin and pemetrexed, every 21 days for two cycles. P/D was performed 4–6 weeks after induction CT, post-operative RT 3–6 weeks after surgery, while post-operative CT was given 4–6 weeks after RT, with the same schedule of induction. Results: All patients showed objective response or stability of disease at the restaging following induction CT and underwent surgery by posterolateral thoracotomy. There were two cases of cardiac arrest as major intraoperative complication, both resolved by manual cardiac massage. Minor complications included one hemidiaphragm elevation, 1 anemia requiring blood transfusion, one wound infection, and two persistent air leaks. Median overall survival was 32.1 months, median progression free survival was 23.7 months. Conclusions: These results suggest the feasibility of these trimodality treatment scheme for early stage MPM patients. Larger series and long-term prospective studies are needed to confirm the validity of this strategy. [ABSTRACT FROM AUTHOR]

Pseudoxanthoma elasticum (PXE) is a rare connective tissue disorder. The main clinical features of this condition are characteristic skin lesions, angioid streaks of the fundus oculi, and occlusive vascular disease. Gastric hemorrhage is a rare complication. A gastroscopic examination was performed on two patients with PXE who presented with upper gastrointestinal tract bleeding. The two patients had submucosal yellowish nodular lesions similar to the xanthoma-like skin lesions seen in the disease. We suggest that a diagnosis of PXE be considered for any patient with gastrointestinal hemorrhage, especially if routine clinical and endoscopic examination fail to reveal the cause, and if raised yellow plaque-like lesions are seen in the stomach by endoscopy.

Hepatocellular carcinoma (HCC) is the most common liver cancer and is among the leading causes of cancer-related death worldwide. There is no reliable biomarker for the early diagnosis of HCC. Circulating microRNAs (miRNAs) have attracted attention as potential biomarkers of disease. By small-RNA next-generation sequencing, the analysis of serum miRNAs led to the identification of molecular signatures able to discriminate advanced HCC from early HCC (n = 246); advanced HCC from CIRRHOSIS (n = 299); advanced HCC from HEALTHY (n = 320); HEALTHY from early HCC (n = 343); and HEALTHY from CIRRHOSIS (n = 414). Cirrhotic patients and early HCC patients exhibited similar serum miRNA profiles, yet a small number of miRNAs (n = 57) were able to distinguish these two classes of patients. A second objective of the study was to identify serum miRNAs capable of predicting the response to therapy in patients with advanced HCC. All patients were treated with sorafenib as first-line therapy: 24 were nonresponsive and 24 responsive. Analysis of circulating miRNAs revealed a 54 miRNAs signature able to separate the two subgroups. This study suggested that circulating miRNAs could be useful biomarkers for monitoring patients with liver diseases ranging from cirrhosis to advanced HCC and possibly predicting susceptibility to first-line treatment based on sorafenib.

Background & Aims: Chronic hepatitis D virus (HDV) often leads to end-stage liver disease and hepatocellular carcinoma (HCC). Comprehensive data pertaining to large populations with HDV and HCC are missing, therefore we sought to assess the characteristics, management, and outcome of these patients, comparing them to patients with hepatitis B virus (HBV) infection. Methods: We analysed the Italian Liver Cancer database focusing on patients with positivity for HBV surface antigen and anti-HDV antibodies (HBV/HDV, n = 107) and patients with HBV infection alone (n = 588). Clinical and oncological characteristics, treatment, and survival were compared in the two groups. Results: Patients with HBV/HDV had worse liver function [Model for End-stage Liver Disease score: 11 vs. 9, p<.0001; Child-Turcotte-Pugh score: 7 vs. 5, p<.0001] than patients with HBV. HCC was more frequently diagnosed during surveillance (72.9% vs. 52.4%, p = .0002), and the oncological stage was more frequently Milan-in (67.3% vs. 52.7%, p = .005) in patients with HBV/HDV. Liver transplantation was more frequently performed in HBV/HDV than in HBV patients (36.4% vs. 9.5%), while the opposite was observed for resection (8.4% vs. 20.1%, p<.0001), and in a competing risk analysis, HBV/HDV patients had a higher probability of receiving transplantation, independently of liver function and oncological stage. A trend towards longer survival was observed in patients with HBV/HDV (50.4 vs. 44.4months, p = .106). Conclusions: In patients with HBV/HDV, HCC is diagnosed more frequently during surveillance, resulting in a less advanced cancer stage in patients with more deranged liver function than HBV alone. Patients with HBV/HDV have a heightened benefit from liver transplantation, positively influencing survival. [ABSTRACT FROM AUTHOR]

Patients with cirrhosis and hepatitis C virus (HCV) infection treated with direct-acting antivirals (DAAs) are still at risk for developing hepatocellular carcinoma (HCC). We aimed to identify features of de novo or recurrent HCCs in these patients, and factors associated with HCC development, in a large cohort of patients with cirrhosis who received treatment with DAAs. In a retrospective study, we collected data from 565 patients with cirrhosis (median age, 64 years; range, 28–87 years; 60% male, 49% infected with HCV genotype 1; median liver stiffness measurement [LSM], 19.1 kPa; 87% Child-Pugh-Turcotte score A) treated with DAAs at a single center in Italy, from December 2014 through 2016. Cirrhosis was defined based on clinical features, histologic factors (METAVIR F4), or LSM >11.9 kPa. Patients were assessed (complete blood analysis and HCV-RNA quantification) every 4 weeks during treatment; at weeks 4, 12, and 24 afterward; and at 6-month intervals thereafter. HCC surveillance was performed by ultrasound or CT scans every 3–6 months, based on history of HCC. Non-invasive markers of fibrosis, such as ratio of aspartate aminotransferase to platelets, fibrosis-4 (FIB-4) score, and LSMs were assessed. During a median 25 months of follow up (range, 3–39 months), HCC developed in 28/505 patients without a history of HCC (de novo HCC); the 3-year estimated cumulative probability for HCC was 6% (95% CI, 4%–9%). Of patients with de novo HCC, 75% had a single tumor and 82% of these were Barcelona liver cancer stage 0–A; the median level of alpha-fetoprotein was 6 ng/mL (range, 1.0–9240 ng/mL). Male sex (hazard ratio [HR], 6.17; 95% CI, 1.44–26.47; P =.01), diabetes (HR, 2.52; 95% CI, 1.08–5.87; P =.03), LSM (HR, 1.03; 95% CI, 1.01–1.06; P =.01), and FIB-4 score (HR, 1.08; 95% CI, 1.01–1.14; P =.01) were independently associated with de novo HCC. HCC developed in 20/60 patients with a history of HCC (HCC recurrence); the 3-year cumulative probability for recurrence was 43% (95% CI, 20%–61%). In the 20 patients with HCC recurrence, 11 had a single tumor and 90% were Child-Pugh-Turcotte score A. Diabetes was independently associated with HCC recurrence (HR, 4.12; 95% CI, 1.55–10.93; P =.004). In a large, single-center cohort of consecutive patients with cirrhosis and who received DAA treatment for HCV infection, most liver tumors were identified at early stages. Male sex, diabetes, and non-invasive markers of liver fibrosis can be used to identify patients at increased risk for HCC following DAAs therapy. [ABSTRACT FROM AUTHOR]

Simple Summary: Sarcopenia, conceived as low skeletal muscle mass and function, has been associated with worse outcomes in patients treated with Sorafenib for advanced HCC, with data coming mainly from the Oriental series. Skeletal muscle mass can be easily quantified from abdominal CT scans performed for advanced HCC staging. Sarcopenia and impaired liver function (MELD > 9) are strong predictors of unfavorable outcomes in patients affected by advanced HCC treated with Sorafenib. Their copresence can identify a subset of patients with particularly bad prognoses. Background and aims: Sarcopenia has been associated with poor outcomes in patients with cirrhosis and hepatocellular carcinoma. We investigated the impact of sarcopenia on survival in patients with advanced hepatocellular carcinoma treated with Sorafenib. Methods: A total of 328 patients were retrospectively analyzed. All patients had an abdominal CT scan within 8 weeks prior to the start of treatment. Two cohorts of patients were analyzed: the "Training Group" (215 patients) and the "Validation Group" (113 patients). Sarcopenia was defined by reduced skeletal muscle index, calculated from an L3 section CT image. Results: Sarcopenia was present in 48% of the training group and 50% of the validation group. At multivariate analysis, sarcopenia (HR: 1.47, p = 0.026 in training; HR 1.99, p = 0.033 in validation) and MELD > 9 (HR: 1.37, p = 0.037 in training; HR 1.78, p = 0.035 in validation) emerged as independent prognostic factors in both groups. We assembled a prognostic indicator named "SARCO-MELD" based on the two independent prognostic factors, creating three groups: group 1 (0 prognostic factors), group 2 (1 factor) and group 3 (2 factors), the latter with significantly worse survival and shorter time receiving treatment.

Purpose: to evaluate the clinical impact of a protocol for the image-guided percutaneous microwave ablation (MWA) of hepatocellular carcinoma (HCC) that includes cone-beam computed tomography (CBCT), fusion imaging and ablation volume prediction in patients with hepatocellular carcinoma unsuitable for standard ultrasound (US) guidance. Materials and Methods: this study included all patients with HCC treated with MWA between January 2021 and June 2022 in a tertiary institution. Patients were divided into two groups: Group A, treated following the protocol, and Group B, treated with standard ultrasound (US) guidance. Follow-up images were reviewed to assess residual disease (RD), local tumor progression (LTP) and intrahepatic distant recurrence (IDR). Ablation response at 1 month was also evaluated according to mRECIST. Baseline variables and outcomes were compared between the groups. For 1-month RD, propensity score weighting (PSW) was performed. Results: 80 consecutive patients with 101 HCCs treated with MWA were divided into two groups. Group A had 41 HCCs in 37 patients, and Group B had 60 HCCs in 43 patients. Among all baseline variables, the groups differed regarding their age (mean of 72 years in Group A and 64 years in Group B, respectively), new vs. residual tumor rates (48% Group A vs. 25% Group B, p < 0.05) and number of subcapsular tumors (56.7% Group B vs. 31.7% Group A, p < 0.05) and perivascular tumors (51.7% Group B vs. 17.1% Group A, p < 0.05). The protocol led to repositioning the antenna in 49% of cases. There was a significant difference in 1-month local response between the groups measured as the RD rate and mRECIST outcomes. LTP rates at 3 and 6 months, and IDR rates at 1, 3 and 6 months, showed no significant differences. Among all variables, logistic regression after PSW demonstrated a protective effect of the protocol against 1-month RD. Conclusions: The use of CBCT, fusion imaging and ablation volume prediction during percutaneous MWA of HCCs provided a better 1-month tumor local control. Further studies with a larger population and longer follow-up are needed. [ABSTRACT FROM AUTHOR]

Background and Aims: Hepatocellular carcinoma (HCC) recurrence is common in patients treated with liver resection (LR). In this study, we aimed to evaluate the incidence and preoperative predictors of non‐transplantable recurrence in patients with single HCC ≤5 cm treated with frontline LR. Methods: From the Italian Liver Cancer (ITA.LI.CA) database, 512 patients receiving frontline LR for single HCC ≤5 cm were retrieved. Incidence and predictors of recurrence beyond Milan criteria (MC) and up‐to‐seven criteria were compared between patients with HCC <4 and ≥4 cm. Results: During a median follow‐up of 4.2 years, the overall recurrence rate was 55.9%. In the ≥4 cm group, a significantly higher proportion of patients recurred beyond MC at first recurrence (28.9% vs. 14.1%; p < 0.001) and overall (44.4% vs. 25.2%; p < 0.001). Similar results were found considering recurrence beyond up‐to‐seven criteria. Compared to those with larger tumours, patients with HCC <4 cm had a longer recurrence‐free survival and overall survival. HCC size ≥4 cm and high alpha‐fetoprotein (AFP) level at the time of LR were independent predictors of recurrence beyond MC (and up‐to‐seven criteria). In the subgroup of patients with available histologic information (n = 354), microvascular invasion and microsatellite lesions were identified as additional independent risk factors for non‐transplantable recurrence. Conclusions: Despite the high recurrence rate, LR for single HCC ≤5 cm offers excellent long‐term survival. Non‐transplantable recurrence is predicted by HCC size and AFP levels, among pre‐operatively available variables. High‐risk patients could be considered for frontline LT or listed for transplantation even before recurrence. [ABSTRACT FROM AUTHOR]

Radiation therapy (RT) is the standard of care in patients with locoregional or isolated vaginal recurrence who never underwent irradiation. It is often associated with brachytherapy (BT), whereas chemotherapy (CT) is a rare treatment option. We systematically searched the PubMed and Scopus databases in February 2023. We included patients with relapsed endometrial cancer, describing the treatment of locoregional recurrence, and reporting at least one outcome of interest—disease-free survival (DFS), overall survival (OS), recurrence rate (RR), site of recurrence, and major complications. A total of 15 studies fulfilled the inclusion criteria. Overall, 11 evaluated RT only, 3 evaluated CT, and 1 analyzed oncological outcomes after administration with a combination of CT and RT. In total, 4.5-year OS ranged from 16% to 96%, and DFS ranged from 36.3% to 100% at 4.5 years. RR ranged from 3.7% to 98.2% during a median follow-up of 51.5 months. Overall, RT showed a 4.5-year DFS from 40% to 100%. CT revealed 36.3% DFS at 4.5 years. RT showed a 4.5-year OS ranging from 16% to 96%, whereas CT revealed a 27.7% OS rate. It would be appropriate to test multi-modality regimens to evaluate outcomes and toxicity. EBRT and BT are the most employed options to treat vaginal recurrences. [ABSTRACT FROM AUTHOR]

Bulevirtide recently received conditional approval from the EMA for the treatment of chronic hepatitis delta, but the ideal duration of therapy is unknown. Herein, we describe the first case of hepatitis delta cure following 3 years of bulevirtide monotherapy in a patient with compensated cirrhosis and esophageal varices. During the 72-week off-bulevirtide follow-up, virological and biochemical responses were maintained. In the off-therapy liver biopsy, intrahepatic HDV RNA and hepatitis D antigen were undetectable, <1% of hepatocytes were hepatitis B surface antigen positive and all were negative for hepatitis B core antigen. Ishak grading and staging were improved following treatment. [ABSTRACT FROM AUTHOR]

Basal cell carcinoma, squamous cell carcinoma, and Merkel cell carcinoma are the three main types of nonmelanoma skin cancers and their rates of occurrence and mortality have been steadily rising over the past few decades. For radiologists, it is still difficult to treat patients with advanced nonmelanoma skin cancer. Nonmelanoma skin cancer patients would benefit greatly from an improved diagnostic imaging-based risk stratification and staging method that takes into account patient characteristics. The risk is especially elevated among those who previously received systemic treatment or phototherapy. Systemic treatments, including biologic therapies and methotrexate (MTX), are effective in managing immune-mediated diseases; however, they may increase susceptibility to NMSC due to immunosuppression or other factors. Risk stratification and staging tools are crucial in treatment planning and prognostic evaluation. PET/CT appears more sensitive and superior to CT and MRI for nodal and distant metastasis as well as in surveillance after surgery. The patient treatment response improved with advent and utilization of immunotherapy and different immune-specific criteria are established to standardized evaluation criteria of clinical trials but none of them have been utilized routinely with immunotherapy. The advent of immunotherapy has also arisen new critical issues for radiologists, such as atypical response pattern, pseudo-progression, as well as immune-related adverse events that require early identification to optimize and improve patient prognosis and management. It is important for radiologists to have knowledge of the radiologic features site of the tumor, clinical stage, histological subtype, and any high-risk features to assess immunotherapy treatment response and immune-related adverse events.

Treatment-induced cardiac toxicity represents an important issue in non-small cell lung cancer (NSCLC) patients, and no biomarkers are currently available in clinical practice. A novel and easy-to-calculate marker is the quantitative analysis of calcium plaque in the coronary, calculated on CT. It is called the Agatston score (or CAD score). At the same time, other potential predictors include cardiac ultrasonography and anamnesis of the patients. Our work aimed to correlate cardiac biomarkers with overall survival (OS) in NSCLC patients. We retrospectively analyzed patients with NSCLC discussed in the Multidisciplinary Tumor Board of our Institute for the present analysis between January 2018 and July 2022. Inclusion criteria were the availability of basal CT imaging of the thorax, cardiac ultrasonography with the calculation of ejection fraction (EF), and complete anamnesis, including assessment of co-pathologies and pharmacological drugs. The clinical data of the patients were retrospectively collected, and the CAD scores was calculated on a CT scan. All of these parameters were correlated with overall survival (OS) with univariate analysis (Kaplan–Meier analysis) and multivariate analysis (Cox regression analysis). Following the above-mentioned inclusion criteria, 173 patients were included in the present analysis. Of those, 120 patients died in the follow-up period (69.6%), and the median overall survival (OS) was 28 months (mean 47.2 months, 95% CI, 36–57 months). In univariate analysis, several parameters that significantly correlated with lower OS were the stage (p < 0.001), the CAD grading (p < 0.001), history of ischemic heart disease (p: 0.034), use of beta blocker drugs (p: 0.036), and cardiac ejection fraction (p: 0.005). In multivariate analysis, the only parameters that remained significant were as follows: CAD score (p: 0.014, OR 1.56, 95% CI: 1.04–1.83), stage (p: 0.016, OR: 1.26, 95% CI: 1.05–1.53), and cardiac ejection fraction (p: 0.011, OR 0.46, 95% CI: 0.25–0.84). Both CAD score and ejection fraction are correlated with survival in NSCLC patients at all stages of the disease. Independently from the treatment choice, a cardiological evaluation is mandatory for patients with NSCLC. [ABSTRACT FROM AUTHOR]

Despite being usually delivered in oncological patients, radiotherapy can be used as a successful treatment for several non-malignant disorders. Even though this use of radiotherapy has been scarcely investigated since the 1950s, more recent interest has actually shed the light on this approach. Thus, the aim of this narrative review is to analyze the applications of non-oncological radiotherapy in different disorders. Key references were derived from a PubMed query. Hand searching and clinicaltrials.gov were also used. This review contains a narrative report and a critical discussion of non-oncological radiotherapy approaches. In conclusion, non-oncological radiotherapy is a safe and efficacious approach to treat several disorders that needs to be further investigated and used in clinical practice. [ABSTRACT FROM AUTHOR]

As the long-term benefits of a sustained virological response (SVR) in HCV-related cirrhosis following direct-acting antiviral (DAA) treatment remain undefined, we assessed the incidence and predictors of liver-related events (LREs), non-liver-related events (NLREs) and mortality in DAA-treated patients with cirrhosis. Consecutive patients with cirrhosis and SVR were enrolled in a longitudinal, single-center study, and divided into 3 cohorts: Cohort A (Child-Pugh A without a previous LRE), Cohort B (Child-Pugh B or Child-Pugh A with prior non-hepatocellular carcinoma [HCC] LREs), Cohort C (previous HCC). A total of 636 patients with cirrhosis (median 65 years-old, 58% males, 89% Child-Pugh A) were followed for 51 (8-68) months (Cohort A n = 480, Cohort B n = 89, Cohort C n = 67). The 5-year estimated cumulative incidences of LREs were 10.4% in Cohort A vs. 32.0% in Cohort B (HCC 7.7% vs. 19.7%; ascites 1.4% vs. 8.6%; variceal bleeding 1.3% vs. 7.8%; encephalopathy 0 vs. 2.5%) vs. 71% in Cohort C (HCC only) (p <0.0001). The corresponding figures for NLREs were 11.7% in Cohort A vs. 17.9% in Cohort B vs. 17.5% in Cohort C (p = 0.32). The 5-year estimated probabilities of liver-related vs. non-liver-related deaths were 0.5% vs. 4.5% in Cohort A , 16.2% vs. 8.8% in Cohort B and 12.1% vs. 7.7% in Cohort C. The all-cause mortality rate in Cohort A was similar to the rate expected for the general population stratified by age, sex and calendar year according to the Human Mortality Database, while it was significantly higher in Cohort B. Patients with cirrhosis and an SVR on DAAs face risks of liver-related and non-liver-related events and mortality; however, their incidence is strongly influenced by pre-DAA patient history. In this large single-center study enrolling patients with hepatitis C virus (HCV)-related cirrhosis cured by direct-acting antivirals, pre-treatment liver disease history strongly influenced long-term outcomes. In patients with HCV-related cirrhosis, hepatocellular carcinoma was the most frequent liver-related complication after viral cure. Due to improved long-term outcomes, patients with cirrhosis after HCV cure are exposed to a significant proportion of non-liver-related events. [Display omitted] • Long-term outcomes in patients with HCV-related cirrhosis after SVR are influenced by liver disease history. • HCC remains the most frequent liver-related event after DAA cure. • Patients with cirrhosis after SVR are exposed to a significant proportion of non-liver related events. • Mortality of patients with stable compensated cirrhosis was similar to the general population.

To assess if the modified strategies adopted to manage HCC during the COVID-19 pandemic allowed us to maintain the standard of care, we compared selected KPI in 2020 with those generated in 2019, in patients with HCC discussed in a weekly multidisciplinary team meeting (MDTM). We were able to maintain a performance comparable with the previous year as far as the timeframe between visit and MDTM, while the timeframe between MDTM and HCC treatment was even shorter during the second wave of pandemic compared with the same period of 2019.

Background: To compare WBC counts during treatment of localized prostate cancer with either conventionally fractionated (CF) or moderately hypofractionated (HYPO) radiotherapy.Methods: Weekly blood test results were extracted from the charts of patients treated within a phase III study comparing HYPO to CF. In order to compare WBC counts at the same nominal dose in both arms and thus to tease out the effect of fractionation, for each recorded WBC value the corresponding cumulative total dose was extracted as well. WBC counts were binned according to percentiles of the delivered dose and three dose levels were identified at median doses of 16, 34.1 and 52 Gy, respectively. A General Linear Model based on mixed design Analysis Of Variance (ANOVA) was used to test variation of WBC counts between the two treatment arms.Results: Out of 168 randomized patients, 140 (83.3%) had at least one observation for each one of the selected dose levels and were included in the analysis. Mean counts were lower in the CF than the HYPO arm at all selected dose levels, reaching a statistically significant difference at dose level #3 (5397/mm3 vs 6038/mm3 for CF and HYPO, respectively, p = 0.004). The GLM model confirms that the impact of dose on WBC counts is significantly lower in the HYPO arm over the CF one (Greenhouse-Geisser test, p = 0.04). Interestingly, while WBC counts tend to drop throughout all dose levels in the CF arm, this is the case only in the earlier part of treatment in the HYPO arm.Conclusion: This secondary analysis of a phase III study shows that dose fractionation is correlated to WBC drop during treatment of localized prostate cancer, favoring HYPO over CF.

All Societies, AASLD, EASL, APASL and JSH, identify patients with cirrhosis as a target population for surveillance, with minor differences for additional categories of patients, such as chronic hepatitis B and hepatitis C patients with advanced fibrosis. According to AASLD, liver disease related to metabolic diseases including diabetes and obesity is a recognized target of screening, since those conditions have been causally related to HCC. All societies endorse radiological non-invasive techniques as the mainstay for early diagnosis of HCC, but discrepancies exist between Societies on the utilization of contrast-enhanced ultrasound and utilization of serum markers for surveillance and diagnosis of HCC. The diagnostic algorithm of the international societies differ substantially in the anatomic paradigm of EASL and APASL which identify 1 cm size as the starting point for radiological diagnosis of HCC compared to APASL algorithm based on the dynamic pattern of contrast imaging, independently on tumour size. While strengthening prediction in individual patients is expected to improve cost-effectiveness ratios of screening, the benefits of pre-treatment patient stratification by clinical, histological and genetic scores remain uncertain and exclusion of patients with severe co-morbidities and advanced age is still debated.

Background & Aims Although patients infected by genotype 1b hepatitis C virus (HCV) with Q 70 and/or M 91 core gene mutations have an almost five-fold increased risk of developing hepatocellular carcinoma (HCC) and increased insulin resistance, the absence of a suitable experimental system has precluded direct experimentation on the effects of these mutations on cellular gene expression. Methods HuH7 cells were treated long-term with human serum to induce differentiation and to produce a model system for testing high-risk and control HCV. For clinical validation, profiles of infected cells were compared to each other and to those of liver biopsies of patients with early-stage HCV-related cirrhosis followed prospectively for up to 23 years (n = 216). Results Long-term culture in human serum produced growth-arrested, hepatocyte-like cells whose gene profile overlapped significantly with that of primary human hepatocytes. High-risk (Q 70 /M 91 ) and control (R 70 /L 91 ) viruses had dramatically different effects on gene expression of these cells. The high-risk virus enhanced expression of pathways associated with cancer and type II diabetes, while the control virus enhanced pathways associated with oxidative phosphorylation. Of special clinical relevance, the transcriptome of cells replicating the high-risk virus correlated significantly with an HCC high-risk profile in patients (Bonferroni-corrected p = 0.03), whereas no such association was observed for non-HCC-related clinical outcomes. Conclusions The cell-based system allowed direct head-to-head comparison of HCV variants, and provided experimental support for previous clinical data indicating an oncogenic effect of core gene mutations. This simple experimental system distinguished HCV variants and will enable future mechanistic analysis and exploration of interventional approaches. [ABSTRACT FROM AUTHOR]

Simple Summary: Interventional radiology image-guided locoregional therapies for the treatment of HCC have demonstrated to be characterized by immunomodulatory effects on the tumoral microenvironment, and, possibly, systemic. Immunotherapy has gained an important role in the treatment of HCC over the last several years. Currently, there is great interest in combining locoregional therapies with immunotherapy, as this could open a new chapter in the history of HCC treatment. In this review, after describing the immune system changes caused by the tumor, we describe, for each locoregional therapy, technique and immunomodulatory effects. Then, we describe the current status of immunotherapy in HCC and report the ongoing clinical studies testing the combination treatment. Image-guided locoregional therapies (LRTs) are a crucial asset in the treatment of hepatocellular carcinoma (HCC), which has proven to be characterized by an impaired antitumor immune status. LRTs not only directly destroy tumor cells but also have an immunomodulating role, altering the tumor microenvironment with potential systemic effects. Nevertheless, the immune activation against HCC induced by LRTs is not strong enough on its own to generate a systemic significant antitumor response, and it is incapable of preventing tumor recurrence. Currently, there is great interest in the possibility of combining LRTs with immunotherapy for HCC, as this combination may result in a mutually beneficial and synergistic relationship. On the one hand, immunotherapy could amplify and prolong the antitumoral immune response of LRTs, reducing recurrence cases and improving outcome. On the other hand, LTRs counteract the typical immunosuppressive HCC microenvironment and status and could therefore enhance the efficacy of immunotherapy. Here, after reviewing the current therapeutic options for HCC, we focus on LRTs, describing for each of them the technique and data on its effect on the immune system. Then, we describe the current status of immunotherapy and finally report the recently published and ongoing clinical studies testing this combination. [ABSTRACT FROM AUTHOR]

Background and Aims: The efficacy of systemic therapy for unresectable advanced hepatocellular carcinoma (aHCC) has not been proven in patients with Child-Pugh (C-P) B cirrhosis. Nevertheless, in real-world these patients are treated both with tyrosine kinase inhibitors (TKIs) and with metronomic capecitabine (MC). This study aimed to compare sorafenib and MC outcomes versus best supportive care (BSC) in C-P B patients., Method: Between 2008 and 2020, among 774 C-P B patients with aHCC not amenable/responsive to locoregional treatments, 410 underwent sorafenib, 62 MC, and 302 BSC. The propensity score matching method was used to correct the baseline unbalanced prognostic factors., Results: In the unmatched population, median OS was 9.7 months in patients treated with sorafenib, 8.0 with MC, and 3.9 months with BSC. In sorafenib vs. BSC-matched patients (135 couples), median OS was 7.3 (4.9-9.6) vs. 3.9 (2.6-5.2) months (p<0.001). ECOG-Performance Status, tumor size, macrovascular invasion, AFP, treatment-naive, and sorafenib were independent predictors of survival. In MC vs. BSC-matched patients (40 couples), median OS was 9.0 (0.2-17.8) vs.3.0 (2.2-3.8) months (p<0.001). Median OS did not differ (p = 0.283) in sorafenib vs. MC-matched patients (55 couples)., Conclusion: C-P B patients with aHCC undergoing BSC have poor survival. Both Sorafenib and MC treatment improve their prognosis., Competing Interests: Conflict of interest GC declares consulting fees from Bayer, Roche, Ipsen, Merck Sharp & Dohme, Eisai, and AstraZeneca; FGF (advisory board, consulting fees): AbbVie, Bayer, Eisai, Gilead, MSD, and Intercept; EGG (advisory board, consulting fees): Astra Zeneca, Eisai, MSD, and Roche; GR (lectures, advisory board, consulting fees): Gilead, Alfa Wasserman, Intercept, and Eisai; FT (research grant, advisory board, consulting fees): Astra Zeneca, AbbVie, Bayer, Eisai, Gilead, MSD, and Roche.

Chronic liver disease and cancer are global health challenges. The role of the circadian clock as a regulator of liver physiology and disease is well established in rodents, however, the identity and epigenetic regulation of rhythmically expressed genes in human disease is less well studied. Here we unravel the rhythmic transcriptome and epigenome of human hepatocytes using male human liver chimeric mice. We identify a large number of rhythmically expressed protein coding genes in human hepatocytes of male chimeric mice, which includes key transcription factors, chromatin modifiers, and critical enzymes. We show that hepatitis C virus (HCV) infection, a major cause of liver disease and cancer, perturbs the transcriptome by altering the rhythmicity of the expression of more than 1000 genes, and affects the epigenome, leading to an activation of critical pathways mediating metabolic alterations, fibrosis, and cancer. HCV-perturbed rhythmic pathways remain dysregulated in patients with advanced liver disease. Collectively, these data support a role for virus-induced perturbation of the hepatic rhythmic transcriptome and pathways in cancer development and may provide opportunities for cancer prevention and biomarkers to predict HCC risk., (© 2024.

Importance: The 2022 Barcelona Clinic Liver Cancer algorithm currently discourages liver resection (LR) for patients with multinodular hepatocellular carcinoma (HCC) presenting with 2 or 3 nodules that are each 3 cm or smaller., Objective: To compare the efficacy of liver resection (LR), percutaneous radiofrequency ablation (PRFA), and transarterial chemoembolization (TACE) in patients with multinodular HCC., Design, Setting, and Participants: This cohort study is a retrospective analysis conducted using data from the HE.RC.O.LE.S register (n = 5331) for LR patients and the ITA.LI.CA database (n = 7056) for PRFA and TACE patients. A matching-adjusted indirect comparison (MAIC) method was applied to balance data and potential confounding factors between the 3 groups. Included were patients from multiple centers from 2008 to 2020; data were analyzed from January to December 2023., Interventions: LR, PRFA, or TACE., Main Outcomes and Measures: Survival rates at 1, 3, and 5 years were calculated. Cox MAIC-weighted multivariable analysis and competing risk analysis were used to assess outcomes., Results: A total of 720 patients with early multinodular HCC were included, 543 males (75.4%), 177 females (24.6%), and 350 individuals older than 70 years (48.6%). There were 296 patients in the LR group, 240 who underwent PRFA, and 184 who underwent TACE. After MAIC, LR exhibited 1-, 3-, and 5-year survival rates of 89.11%, 70.98%, and 56.44%, respectively. PRFA showed rates of 94.01%, 65.20%, and 39.93%, while TACE displayed rates of 90.88%, 48.95%, and 29.24%. Multivariable Cox survival analysis in the weighted population showed a survival benefit over alternative treatments (PRFA vs LR: hazard ratio [HR], 1.41; 95% CI, 1.07-1.86; P = .01; TACE vs LR: HR, 1.86; 95% CI, 1.29-2.68; P = .001). Competing risk analysis confirmed a lower risk of cancer-related death in LR compared with PRFA and TACE., Conclusions and Relevance: For patients with early multinodular HCC who are ineligible for transplant, LR should be prioritized as the primary therapeutic option, followed by PRFA and TACE when LR is not feasible. These findings provide valuable insights for clinical decision-making in this patient population.
