Possible biomarkers found for progression to liver cancer in chronic HCV infection
according to the results of a biochemical analysis of human blood samples performed by PhD student Paywast J. Jalal of the University of Sulaimani (Iraq) and colleagues.
Archived HCV-positive serum samples, including those from 31 patients who had developed HCC, were retrieved from the Trent HCV clinical cohort. They were compared with each other over time and against samples from HCV-infected individuals in the cohort who did not develop HCC. In addition, HCV-negative serum samples were obtained commercially and assessed identically. Circulating liver-expressed lectins, ficolin-2, ficolin-3, and MBL were all examined as potential biomarkers for the development of HCC, the authors wrote in Virology.
Binding of ficolin-3 to reference ligands was greater in chronic HCV infection, while ficolin-2 and MBL were significantly elevated in individuals who develop HCC, compared with HCV-infected individuals without HCC. Ficolin-2 and MBL were found to be elevated at 1 and 3 years prior to HCC diagnosis, respectively, suggesting they could be used as prognostic serum markers for the development of HCC.
“The strong evidence for an association between elevated MBL binding activity and the development of HCC is supportive for a larger prospective study of these biomarkers in HCV-induced liver cancer,” the researchers concluded.
This study was funded by a split-site PhD scholarship between the University of Sulaimani and the University of Nottingham (England). The authors reported they had no conflicts.

Novel capsid assembly modulator shows promise in HBV
For adults with chronic hepatitis B virus infection, treatment with a novel investigational capsid assembly modulator was well tolerated and showed antiviral activity against HBV, according to the results of a phase 1 study of 73 patients.
“Substantial and correlated reductions in serum HBV DNA and HBV RNA levels were observed consistently with the higher-dose cohorts and were notably greatest for combination treatment with NVR 3-778 and pegIFN [pegylated interferon],” Man Fung Yuen, MD, of the University of Hong Kong, and his associates wrote in a report published in Gastroenterology. Hence, this first-in-class capsid assembly modulator might help prolong treatment responses, “most likely as a component of new combination treatment regimens for HBV-infected patients.” However, one patient developed severe rash immediately after completing treatment that took 6 months of intensive outpatient treatment to resolve, they noted.
Chronic viral hepatitis due to HBV is a major cause of early death worldwide, and new therapies are needed to help prevent severe liver disease and liver death from this infection. Current treatments for HBV infection consist of nucleoside or nucleotide analogs or pegylated interferon. These suppress HBV replication in many patients, but most patients do not achieve durable responses. Consequently, most patients require long-term treatment with HBV nucleosides and nucleotide analogs, which they may find difficult to tolerate or adhere to and to which their infections can become resistant, the researchers said.
The HBV virion contains a viral core protein (HBc) that is required to encapsidate viral polymerase and pregenomic HBV RNA into a nucleocapsid. To target this process, researchers developed NVR 3-778, a first-in-class, orally bioavailable small molecule that binds HBc so that HBc forms a defective capsid that lacks nuclear material. Hence, NVR 3-778 is intended to stop the production of HBV nucleocapsids and keep infected cells from releasing the enveloped infectious viral particles that perpetuate HBV infection.
To assess the safety, pharmacokinetics, and antiviral activity of NVR 3-778, the researchers conducted a phase 1 study of 73 patients with chronic HBV infection who tested positive for hepatitis B e-antigen (HBeAg) and had no detectable cirrhosis. Patients were randomly assigned to receive oral NVR 3-778 (100 mg, 200 mg, or 400 mg daily or 600 mg or 1,000 mg twice daily ) or placebo for 28 days. Some patients received combination therapy with pegylated interferon plus either NVR 3-778 (600 mg twice daily) or placebo. Treatment was generally well tolerated, and adverse events were usually mild and deemed unrelated to therapy. No patient stopped treatment for adverse effects.
The only serious adverse event in the study consisted of grade 3 rash that developed in a 42-year-old male after 22 days of treatment at the lowest dose of NVR 3-778 (100 mg per day). This patient completed treatment and ultimately developed a severe papulovesicular rash with a predominantly acral distribution over the hands, arm, side of neck, and one leg (palmar plantar erythrodysesthesia), the researchers said. “There were no perioral or mucosal lesions, no ecchymotic skin involvement, no bullae, and no systemic manifestations or hematological abnormalities,” they wrote. “The rash was subsequently managed with a psoriasis-like treatment regimen of psoralen, ultraviolet light, and topical steroid ointment during outpatient follow-up and resolved after approximately 6 months.”
Another three cases of “minor” skin rash were considered probably related to treatment in the cohort that received 600 mg NVR 3-778 b.i.d. plus pegylated interferon, the investigators said. Two additional cases of mild rash were deemed unrelated to treatment.
“The observed reductions in HBV RNA confirmed the novel mechanism of NVR 3-778,” the researchers concluded. “This class of compounds can also inhibit replenishment of intranuclear covalently closed circular DNA over time and may have immunomodulatory properties.” Longer treatment periods would be needed to study these mechanisms and to quantify reductions in serum HBsAg and HBeAG, they noted.
Novira Therapeutics developed NVR 3-778 and is a Janssen Pharmaceutical Company. Janssen provided funding for editorial support. Dr. Yuen disclosed relationships with AbbVie, Biocartis, Bristol-Myers Squibb, Gilead Sciences, GlaxoSmithKline, Ionis, Roche, Vir Biotechnology, and several other pharmaceutical companies. Other coinvestigators disclosed ties to pharmaceutical companies; eight reported employment by Novira or a Janssen company.

AGA Clinical Practice Update: Surgical risk assessment and perioperative management in cirrhosis
Patients with cirrhosis should be risk stratified and counseled accordingly before all but the most urgent surgeries, cautions a clinical practice update from the American Gastroenterological Association.
These risks, which include mortality and reflect “the profound effects of hepatic synthetic dysfunction and portal hypertension,” require presurgical evaluation based on CTP score (Child-Pugh class), Model for End-Stage Liver Disease (MELD) score, Mayo Postoperative Mortality Risk Score, or another proven risk-stratification system, writes Patrick G. Northup, MD, of the University of Virginia, Charlottesville, together with his associates. “There is no single definitive risk-stratification system to determine operative risk in all patients with cirrhosis, and we recommend using multiple methods,” they elaborated in Clinical Gastroenterology and Hepatology.
The prevalence of cirrhosis is rising, affected patients are living longer, and liver disease is more advanced and may involve comorbidities that merit consideration of surgery, noted Dr. Northup and his associates. However, cirrhosis increases the risk for serious postoperative complications, including hepatic decompensation, worsening of liver synthetic function, exacerbated portal hypertension, wound dehiscence, pleural effusions, pneumonia, bacterial peritonitis, bleeding, and multiple organ failure. Because clinical trials of surgery in cirrhotic patients are lacking, the experts stress the need for case-by-case management.
There is no definite threshold that precludes all surgeries in cases of cirrhosis, but a Child-Pugh class C (CTP score over 10) or MELD score over 20 greatly increases the risk of postoperative decompensation and death. For these patients, “all but the most urgent and life-saving procedures” should be canceled or postponed until after liver transplantation, the experts wrote. For less severe cirrhosis, it is key to consider the type and anatomic site of the proposed surgery. Hepatobiliary surgeries, other intra-abdominal surgeries, cardiovascular surgeries, and thoracic procedures are most likely to lead to serious complications.
Preoperative care should emphasize control of ascites, variceal bleeding risk, and hepatic encephalopathy. Bleeding and clotting safety thresholds in cirrhosis are unknown, and individualized management, ideally with viscoelastic testing–directed therapy, is warranted instead of protocol transfusions to a target international normalized ratio (INR). Bleeding events are more common in critically ill patients with plasma fibrinogen ratios under 100 mg/dL.
Segmental hepatic resection (usually for malignancy), the most studied procedure in cirrhosis, is generally safe in the absence of clinically significant portal hypertension. For patients who do have portal hypertension, transjugular intrahepatic portosystemic shunt (TIPS) has not clearly been shown to outperform conservative management, although small case series have found that TIPS during deep pelvic or colonic resection decompresses abdominal collaterals.
Because of the risk of poor outcomes, patients with cirrhosis and incompletely controlled ascites should not undergo abdominal hernia repair unless they have an incarceration that is not manually reducible or suspected strangulation. Bariatric surgery is contraindicated in cases of clinically significant portal hypertension but otherwise can be performed at a center with cirrhosis expertise. Sleeve gastrectomy at the same time as liver transplantation is also an option for select patients with obesity.
Elective cholecystectomy should be avoided, and required cases should be performed in experienced centers. “The gallbladder wall may appear thickened on imaging, which may lead to the erroneous diagnosis of acute cholecystitis,” the experts noted. Hence, the diagnosis “should be made only in the appropriate clinical setting, usually in the presence of biliary pain.”
Hepatic decompensation after surgery can be severe enough to merit liver transplantation. There is no agreed-on MELD score that mandates liver transplant evaluation before elective surgery, but the experts recommend doing so if the MELD score is 15 or greater or if risk of mortality within 3 months after surgery exceeds 15%.
Postoperative management of patients with cirrhosis should include aggressive measures to prevent portal hypertension. Monitor renal function closely and avoid volume depletion or overload, the experts advised. Patients should receive only short-acting benzodiazepines and lower opiate doses, administered less often, than in the general population. Avoiding constipation is vital to minimize hepatic encephalopathy, which makes oral rifaximin a better choice than lactulose. Patients should not receive NSAIDs, which can impair renal blood flow. To prevent liver toxicity, they should not be discharged on opiate/acetaminophen combinations, which they might unknowingly take along with another drug that contains acetaminophen.
The experts disclosed no external funding sources and reported having no conflicts of interest.

Ultrasound method predicts liver complications in pediatric transplant
HOUSTON – An ultrasound method for assessing liver stiffness might be useful for predicting which pediatric patients will develop a life-threatening complication of hematopoietic stem cell transplantation.
Shear wave elastography values predicted severe hepatic sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) at least 4 days before standard diagnostic criteria in most patients treated in a small, prospective, two-center study, Sherwin S. Chan, MD, PhD, said at the Transplantation & Cellular Therapy Meetings.
Early identification of SOS/VOD using elastography could be beneficial in light of data showing that timing is critical in the administration of defibrotide, a treatment recommended for severe and very severe patients, according to Dr. Chan, vice chair of radiology for the University of Missouri at Kansas City.
“If you’re able to initiate it early, you can really increase day 100 survival,” Dr. Chan said in an oral presentation.
The data presented included 54 pediatric patients undergoing transplantation at one of two institutions.
At one site, the patients underwent shear wave elastography evaluation 10 days before the conditioning regimen began, and again at 5 and 14 days after the transplant. At the other site, patients with suspected SOS/VOD were enrolled and underwent elastography every other day for up to 10 exams.
Those are very different imaging protocols, Dr. Chan acknowledged in his presentation, noting that the studies started independently and data were pooled as investigators at the two institutions became aware of one another’s work.
A total of 16 patients, or 30%, developed SOS/VOD, Dr. Chan reported. Of those 16 cases, 12 (75%) were severe or very severe by the recent European Society for Blood and Marrow Transplantation (EBMT) criteria.
Increased shear wave elastography velocity was the best predictor of severe SOS/VOD, according to Dr. Chan, with a cutoff value of 1.65 m/s being 92% sensitive and 67% specific for severe SOS/VOD.
That threshold was passed at least 4 days before severe grading or death in 9 out of the 12 severe cases, he added.
Accordingly, a prospective, multicenter trial has been initiated at a number of U.S. centers to investigate whether the findings of this study are generalizable to other patient populations, Dr. Chan said at the meeting held by the American Society of Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research. At this meeting, the American Society for Blood and Marrow Transplantation announced a new name for the society: American Society for Transplantation and Cellular Therapy.
That prospective, multicenter trial is supported by Jazz Pharmaceuticals, according to Dr. Chan, who reported consulting with Jazz Pharmaceuticals in his disclosure statement.

Early identification of SOS/VOD using elastography could be beneficial in light of data showing that timing is critical in the administration of defibrotide, a treatment recommended for severe and very severe patients, according to Dr. Chan, vice chair of radiology for the University of Missouri at Kansas City.
“If you’re able to initiate it early, you can really increase day 100 survival,” Dr. Chan said in an oral presentation.
The data presented included 54 pediatric patients undergoing transplantation at one of two institutions.
At one site, the patients underwent shear wave elastography evaluation 10 days before the conditioning regimen began, and again at 5 and 14 days after the transplant. At the other site, patients with suspected SOS/VOD were enrolled and underwent elastography every other day for up to 10 exams.
Those are very different imaging protocols, Dr. Chan acknowledged in his presentation, noting that the studies started independently and data were pooled as investigators at the two institutions became aware of one another’s work.
A total of 16 patients, or 30%, developed SOS/VOD, Dr. Chan reported. Of those 16 cases, 12 (75%) were severe or very severe by the recent European Society for Blood and Marrow Transplantation (EBMT) criteria.
Increased shear wave elastography velocity was the best predictor of severe SOS/VOD, according to Dr. Chan, with a cutoff value of 1.65 m/s being 92% sensitive and 67% specific for severe SOS/VOD.
That threshold was passed at least 4 days before severe grading or death in 9 out of the 12 severe cases, he added.
Accordingly, a prospective, multicenter trial has been initiated at a number of U.S. centers to investigate whether the findings of this study are generalizable to other patient populations, Dr. Chan said at the meeting held by the American Society of Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research. At this meeting, the American Society for Blood and Marrow Transplantation announced a new name for the society: American Society for Transplantation and Cellular Therapy.
That prospective, multicenter trial is supported by Jazz Pharmaceuticals, according to Dr. Chan, who reported consulting with Jazz Pharmaceuticals in his disclosure statement.

HCV-infected patients in the ED should be tested for advanced liver fibrosis
More than one-third of hepatitis C virus-infected patients in the emergency department (ED) were found to have advanced liver fibrosis and higher mortality, according to the results of a retrospective study of 113 known patients with HCV at a single institution.
As part of an ongoing HCV linkage-to-care (LTC) program, HCV-infected ED patients were retrospectively identified. Components of FIB-4 (a noninvasive serum fibrosis index, which includes age, alanine aminotransferase, aspartate aminotransferase, and platelet count), were abstracted. Patients with an FIB-4 greater than 3.25 were classified with advanced fibrosis and characterized with regard to downstream outcomes at 1 year after enrollment.
The 1-year outcomes after the ED encounter for the 113 patients showed 38 with and 75 patients without advanced fibrosis. Among these, 72 (96%) and 34 (89.5%), respectively, agreed to be linked to HCV care. Ten patients of the total number of patients died within the 1-year follow-up. For those HCV-infected patients with advanced liver fibrosis compared to those without, all-cause mortality was more than fourfold higher, (18.4% [7 patients] vs. 4.0% [3 patients], P = .030), according to Yu-Hsiang Hsieh, PhD, associate professor of emergency medicine at Johns Hopkins University, Baltimore, and his colleagues (Am J Emerg Med. 2019;37[2]:286-90).
“Given the substantial burden of HCV-related illness in urban ED patients nationally, and the recognized fact that EDs are often the only point of contact with the health care system for many of these patients, we propose incorporating FIB-4 based rapid assessment into ED-based HCV screening and LTC programs in order to prioritize LTC for patients with advanced liver fibrosis, as well as routine ED clinical practice,” the researchers concluded.
They reported having no conflicts.

DAAs reduce mortality, cancer risk in HCV study
Direct-acting antivirals significantly decrease risk of hepatocellular carcinoma and mortality in persons with hepatitis C, according to results of the first prospective, longitudinal study to evaluate the effect of the drugs on complications related to the infection.
Compared with no treatment, DAA therapy cut risk of hepatocellular carcinoma by about one-third and all-cause mortality by about half in the study, which included about 10,000 adult patients with chronic hepatitis C virus (HCV) infection treated at 1 of 32 hepatology centers in France (NCT01953458).
There were no signs of increased risk of hepatocellular carcinoma during treatment with DAAs, providing more evidence refuting earlier, single-center reports that had suggested an increased incidence early after treatment. These findings also counterbalance a recent Cochrane review that could not confirm or reject a potential benefit of drugs on long-term morbidity and mortality.
Results of the study, published in the Lancet, are based on analysis of 9,895 patients, including 7,344 who started DAA treatment and 2,551 who remained untreated at a median follow-up of more than 31 months. The median patient age was 56 years, and 53% were men.
Treatment with DAAs reduced risk of hepatocellular carcinoma when compared with no DAA treatment, with a hazard ratio of 0.66 (95% confidence interval, 0.46-0.93), and reduced risk of all-cause mortality, with an HR of 0.48 (95% CI, 0.33-0.70), investigators reported in a multivariable analysis that adjusted for variables including age, sex, fibrosis score, HCV genotype, alcohol use, and more.
“These inverse associations persisted in the subgroup of patients who achieved a sustained virological response, whereas those who did not achieve a sustained virological response were a higher risk for hepatocellular carcinoma,” said the investigators, led by Fabrice Carrat, PhD, of Sorbonne Université, Institut National de la Santé et de la Recherche Médicale (INSERM), Paris.
Sustained virologic response was observed in 94% of patients who had known response status and sufficient follow-up, investigators said.
In patients with cirrhosis at baseline, DAA treatment had a similarly strong association with reduced hepatocellular carcinoma and mortality, with a sustained virologic response rate of 92% in those for whom sufficient data was available, they said.
There was no evidence for an increased risk of hepatocellular carcinoma on treatment, with an adjusted HR of 0.74 (95% CI, 0.49-1.13; P = 0.17), they added.
“Our results support urgent treatment of patients with advanced liver disease and extension of the follow-up of treated patients with less severe disease to assess the long-term clinical effect of direct-acting antiviral treatment,” Dr. Carrat and colleagues said in a commentary on their results.
However, the long-term effect of DAAs on liver decompensation has yet to be clarified, they added, noting that their study excluded patients with decompensated cirrhosis or a history of hepatocellular carcinoma.
Funding for the study came from INSERM, Agence Nationale de la Recherche, DGS (Direction Générale de la Santé), MSD, Janssen, Gilead, AbbVie, Bristol-Myers Squibb, and Roche. Dr. Carrat reported personal fees from Imaxio not related to the present study.

This study provides “substantive evidence” that curing hepatitis C virus with all-oral direct-acting antiviral regimens provides clinical benefits, according to Raymond T. Chung, MD, and his coauthors of a related editorial.
Investigators in this study provide the best evidence so far in support of guidelines that advise direct-acting antiviral (DAA) treatment for all patients with chronic hepatitis C virus (HCV) infection, the editorial’s authors stated.
Results of the French study provide a strong counterpoint to the findings of a recent Cochrane review of DAA trials that could not confirm or reject whether DAAs had effects on long-term morbidity and mortality related to HCV, added Dr. Chung and his coauthors. “Finally, they provide credence to the achievability of the goals set out by the World Health Organization (WHO), not only to eliminate HCV but also to substantially reduce its complications.”
The WHO targets were established in light of earlier evidence that sustained virologic responses are linked to reductions in hepatocellular carcinoma, liver transplantation, and mortality, they said.
“In view of the high sustained virological response and excellent tolerability achieved with DAAs, it seemed highly plausible to envision reductions in chronic HCV infection–related complications with these drugs,” they said in reference to the study by Carrat and colleagues.

NASH: Fastest-growing cause of liver cancer in transplant candidates
Nonalcoholic steatohepatitis may soon supplant chronic hepatitis C as the leading cause of hepatocellular carcinoma among patients awaiting liver transplantation, according to the findings of a national longitudinal registry study.
The proportion of affected patients with nonalcoholic steatohepatitis (NASH) rose nearly 700% between 2002 and 2017 (P less than .0001), making NASH the only etiology to significantly rise in prevalence, reported Zobair Younossi, MD, MPH, of Inova Health System in Falls Church, Va., and his associates. Chronic hepatitis C remained the most common cause of liver cancer during the study period, but its prevalence fell by more than 10% in the last 3 years (2014-2017). These trends reflect the advent of “new, highly effective antiviral regimens” for hepatitis C, the global epidemic of obesity and metabolic syndrome, and the urgent need for effective, safe treatments for NASH, they wrote in Clinical Gastroenterology and Hepatology.
Historically, hepatocellular carcinoma is usually caused by chronic hepatitis C or B infection, but the global rise of obesity and type 2 diabetes mellitus has led to epidemic levels of NASH, a progressive form of nonalcoholic fatty liver disease that lacks useful predictive noninvasive biomarkers or safe treatments. This phenomenon, coupled with the advent of new, often-curative treatments for viral hepatitis, is making NASH a leading driver of both fibrosis and liver transplantation in the United States. To compare trends in liver cancer etiologies among transplant candidates, Dr. Younossi and his associates analyzed data on 158,347 adults who were wait-listed between 2002 and 2017 and captured by the national Scientific Registry of Transplant Recipients.
A total of 26,121 (16.5%) patients awaiting liver transplant had hepatocellular carcinoma. This proportion nearly quadrupled over the study period, from 6% to 23% (P less than .0001) and rose significantly (P less than .0001) for all liver cancer etiologies (hepatitis C and B, alcoholic liver disease, and NASH). However, the absolute rise in prevalence was far greater for NASH (1050%) than for chronic hepatitis C (more than 500%) or any other etiology.
Furthermore, while most (65%) liver cancer cases involved chronic hepatitis C, the proportion of cases involving NASH rose from 2% in 2002 to 18% in 2017 (P less than .0001). By 2017, NASH topped alcoholic liver disease, comorbid hepatitis C with alcoholic liver disease, and chronic hepatitis B as an etiology of hepatocellular carcinoma among patients listed for transplant. Conversely, by 2017, less than 50% of liver cancers were caused by hepatitis C – a more than 10% drop from 2014. Over the study period, NASH was the only etiology whose prevalence significantly increased among transplant-listed patients with hepatocellular carcinoma.
In this study, etiology of liver cancer did not seem to affect the likelihood of either death or transplantation. However, serious cardiovascular disease or late-stage cancer diagnosis might exclude many NASH patients from transplantation, the researchers wrote. “Thus, the population reported here actually may underestimate the true proportion of hepatocellular carcinoma cases related to nonalcoholic fatty liver disease and NASH in the United States. Because NASH is on a trajectory to become the most common cause of hepatocellular carcinoma in the United States, effective prevention strategies and treatment options are urgently needed for this currently underserved patient population.”
Minneapolis Medical Research Foundation is the contractor for the registry and supplied the data. Dr. Younossi reported ties to Bristol-Myers Squibb, Gilead Sciences, AbbVie, Intercept Pharmaceuticals, and GlaxoSmithKline.

However, serious cardiovascular disease or late-stage cancer diagnosis might exclude many NASH patients from transplantation, the researchers wrote. “Thus, the population reported here actually may underestimate the true proportion of hepatocellular carcinoma cases related to nonalcoholic fatty liver disease and NASH in the United States. Because NASH is on a trajectory to become the most common cause of hepatocellular carcinoma in the United States, effective prevention strategies and treatment options are urgently needed for this currently underserved patient population.”

Nonalcoholic steatohepatitis may soon supplant chronic hepatitis C as the leading cause of hepatocellular carcinoma among patients awaiting liver transplantation, according to the findings of a national longitudinal registry study.
The proportion of affected patients with nonalcoholic steatohepatitis (NASH) rose nearly 700% between 2002 and 2017 (P less than .0001), making NASH the only etiology to significantly rise in prevalence, reported Zobair Younossi, MD, MPH, of Inova Health System in Falls Church, Va., and his associates. Chronic hepatitis C remained the most common cause of liver cancer during the study period, but its prevalence fell by more than 10% in the last 3 years (2014-2017). These trends reflect the advent of “new, highly effective antiviral regimens” for hepatitis C, the global epidemic of obesity and metabolic syndrome, and the urgent need for effective, safe treatments for NASH, they wrote in Clinical Gastroenterology and Hepatology.
Historically, hepatocellular carcinoma is usually caused by chronic hepatitis C or B infection, but the global rise of obesity and type 2 diabetes mellitus has led to epidemic levels of NASH, a progressive form of nonalcoholic fatty liver disease that lacks useful predictive noninvasive biomarkers or safe treatments. This phenomenon, coupled with the advent of new, often-curative treatments for viral hepatitis, is making NASH a leading driver of both fibrosis and liver transplantation in the United States. To compare trends in liver cancer etiologies among transplant candidates, Dr. Younossi and his associates analyzed data on 158,347 adults who were wait-listed between 2002 and 2017 and captured by the national Scientific Registry of Transplant Recipients.
A total of 26,121 (16.5%) patients awaiting liver transplant had hepatocellular carcinoma. This proportion nearly quadrupled over the study period, from 6% to 23% (P less than .0001) and rose significantly (P less than .0001) for all liver cancer etiologies (hepatitis C and B, alcoholic liver disease, and NASH). However, the absolute rise in prevalence was far greater for NASH (1050%) than for chronic hepatitis C (more than 500%) or any other etiology.
Furthermore, while most (65%) liver cancer cases involved chronic hepatitis C, the proportion of cases involving NASH rose from 2% in 2002 to 18% in 2017 (P less than .0001). By 2017, NASH topped alcoholic liver disease, comorbid hepatitis C with alcoholic liver disease, and chronic hepatitis B as an etiology of hepatocellular carcinoma among patients listed for transplant. Conversely, by 2017, less than 50% of liver cancers were caused by hepatitis C – a more than 10% drop from 2014. Over the study period, NASH was the only etiology whose prevalence significantly increased among transplant-listed patients with hepatocellular carcinoma.
In this study, etiology of liver cancer did not seem to affect the likelihood of either death or transplantation. However, serious cardiovascular disease or late-stage cancer diagnosis might exclude many NASH patients from transplantation, the researchers wrote. “Thus, the population reported here actually may underestimate the true proportion of hepatocellular carcinoma cases related to nonalcoholic fatty liver disease and NASH in the United States.

Residential HCV program improves veterans’ diagnosis and care
Integrating comprehensive and collaborative hepatitis C virus (HCV) care within a Veterans Affairs residential treatment program can substantially increase diagnosis and treatment of HCV-infected veterans with substance use disorder (SUD), according to the results of an evaluation study for the period from December 2014 to April 2018.
A total of 97.5% (582/597) of patient admissions to the program were screened for HCV infection, and 12.7% (74/582) of the cases were confirmed to be HCV positive. All of the positive cases were sent to an infectious disease (ID) clinic for further evaluation and, if appropriate, to begin HCV pharmacotherapy, according to the report, published in the Journal of Substance Abuse Treatment.
Of the HCV-positive cases, 78.4% (58/74) received pharmacotherapy, with a sustained virologic response rate of 82.8% (48/58), wrote Mary Jane Burton, MD, of the G.V. (Sonny) Montgomery VA Medical Center, Jackson, Miss., and her colleagues.
As part of the program, all veterans admitted to the SUD residential program were offered screening for HCV. Veterans with negative screening results received education about how to remain HCV negative via handouts and veterans who screened positive received brief supportive counseling and were referred to the ID clinic via a consult. Veterans confirmed to have chronic HCV infection receive education and evaluation in the HCV clinic while they attend the residential SUD program. Treatment for HCV is instituted as early as feasible and prescribing is in accordance with VA guidelines (Department of Veterans Affairs, 2018), with the goal of initiating pharmacotherapy treatment for HCV while the veteran is still in the residential program, according to the researchers.
Following discharge from the program, veterans on HCV treatment are scheduled for follow-up every 2 weeks in the HCV treatment clinic for the remainder of their pharmacotherapy, the researchers added.
Patient-level barriers to HCV treatment among the SUD population include reduced health literacy, low health care utilization, comorbid mental health conditions, and poor social support, according to the literature. Because multidisciplinary approaches to HCV treatment that mitigate these barriers have been shown to increase treatment uptake among these patients, the VA program was initiated, the researchers stated. Dr. Burton and her colleagues reported that 18.9% (14/74) of the HCV-positive cases were newly diagnosed and would have likely gone undetected without this program (J Substance Abuse Treatment. 2019;98:9-14).
“We have demonstrated that integrating a comprehensive HCV screening, education, referral, and treatment program within residential SUD treatment is feasible and effective in diagnosing previously unrecognized HCV infections, transitioning veterans into HCV care, and promoting treatment initiation,” the researchers concluded.

mRECIST response to kinase inhibitors predicts survival in HCC
SAN FRANCISCO – Patients with hepatocellular carcinoma (HCC) who have a response to first-line kinase inhibitors based on modified RECIST (mRECIST) criteria live almost a year longer than counterparts who have stable or progressive disease, finds a retrospective post hoc analysis of the REFLECT trial.
“The inability to accurately evaluate response to targeted or locoregional therapies resulted in the adaptation of RECIST to mRECIST, guidelines specifically designed to evaluate response to treatment in HCC,” noted lead investigator Masatoshi Kudo, MD, PhD, of the department of gastroenterology and hepatology, Kindai University Faculty of Medicine, Osaka, Japan. “Based on recommendations from the EASL [European Association for the Study of the Liver] consensus conference in 2000, mRECIST was developed to assess response based on the reduction of viable tumor burden … rather than overall tumor shrinkage. However, EASL clinical practice guidelines also suggested additional studies are needed to validate this approach.”
The investigators analyzed data from REFLECT, a global phase 3 noninferiority, randomized, controlled trial that showed overall survival with the novel kinase inhibitor lenvatinib (Lenvima) was not inferior to that with the older kinase inhibitor sorafenib (Nexavar) in 954 patients with untreated, unresectable HCC (Lancet. 2018;391:1163-73).
The new analysis, reported at the 2019 GI Cancers Symposium, showed that, among all randomized patients, those having an objective response according to mRECIST criteria were 39% less likely to die after other factors were taken into account. The finding was consistent in a landmark analysis, which addresses the issue of lead-time bias.
“Objective response by mRECIST was an independent predictor of overall survival in patients with HCC regardless of treatment,” Dr. Kudo concluded, adding that the findings are consistent with those of several previous studies. “Thus, patients who achieve an objective response can potentially expect a longer overall survival. However, additional studies are needed to further validate the correlation between objective response and overall survival.”
Findings in context
Although the mRECIST criteria overcome some issues with the size-based RECIST criteria in assessing HCC, the former are not without their limitations, noted invited discussant Andrew X. Zhu, MD, PhD, of Harvard Medical School and Massachusetts General Hospital Cancer Center.
These limitations include, for example, the need for more stringent selection of target lesions and the potential for antiangiogenic agents to cause vasoconstriction, complicating measurement. “There is tremendous intraobserver and interobserver variability, and a tremendous learning curve,” he added, noting that in REFLECT the mRECIST overall response rate assessed by independent reviewers was considerably higher than that assessed by investigators.
To date, three other trials of targeted therapies have similarly found an association between mRECIST response and overall survival. But a fourth did not.
“In the era of immunotherapy being actively applied to HCC, it’s important to recognize that this association actually may be agent dependent,” Dr. Zhu said. “Even though the TKIs with antiangiogenic [activity] have shown an improved overall response [going] from RECIST to mRECIST, this has not been recapitulated, at least based on the current experience that we have, with checkpoint inhibitors.”
The REFLECT investigators’ conclusion “is certainly backed by the large dataset from a positive phase 3 trial. It has very sound statistical methodology, and it may actually provide the initial evidence that this biomarker may serve as a potentially relevant surrogate to predict overall survival,” he said.
At the same time, there is reason to be cautious given the post hoc, retrospective nature of the study; the lack of a comparison with conventional RECIST response; absence of analysis of the potential correlation of stable disease with overall survival; and the lumping together of two agents, among other issues.
“For these reasons, I do think additional studies are warranted for prospective validation of the findings,” Dr. Zhu concluded.
Study details
REFLECT patients had an investigator-assessed mRECIST objective response rate of 16.7% overall (24.1% with lenvatinib and 9.2% with sorafenib) and a median overall survival of 13.0 months (13.6 months with lenvatinib and 12.3 months with sorafenib).
Median overall survival was 22.4 months for mRECIST responders and 11.4 months for nonresponders (P less than .001), Dr. Kudo reported at the symposium, sponsored by the American Gastroenterological Association, the American Society for Clinical Oncology, the American Society for Radiation Oncology, and the Society of Surgical Oncology.
In a multivariate analysis, this difference translated to a 39% reduction in risk of death for responders (hazard ratio, 0.61; P less than .0001).
Moreover, the survival advantage of response was evident in landmark analyses, whether response was assessed at 2 months (HR, 0.75; P = .033), at 4 months (HR, 0.72; P = .009), or at 6 months (HR, 0.73; P = .010).
Dr. Kudo disclosed that he receives honoraria or has a consulting or advisory role with several pharmaceutical companies. The presentation was sponsored by Eisai and Merck.

HBV, HCV, HIV testing of new cancer patients advised
Oncologists should consider testing all patients with newly diagnosed cancers for infection with the hepatitis B and C viruses, a multicenter team has recommended.
A prospective study of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV infections among 3,051 patients with newly diagnosed cancers showed that 6.5% of patients tested positive for previous HBV and 0.6% had chronic HBV infection. In addition, 2.4% of patients were positive for HCV, and 1.1% for HIV infections, reported Scott D. Ramsey, MD, PhD, from the Fred Hutchinson Cancer Research Center in Seattle, and colleagues.
“Many patients had no known risk factors for infection, suggesting that current risk-based models for screening may be insufficient. Thus, we believe our results warrant consideration of universal testing of patients with newly diagnosed cancer for HBV and HCV infection, particularly if such an approach is shown to be cost effective,” they wrote in JAMA Oncology.
The investigators noted that patients with undiagnosed hepatitis and/or HIV infections could transmit them to unsuspecting caregivers, adding that “with effective treatments available, not screening for these viruses misses an opportunity to reduce future morbidity associated with these infections and to avoid viral reactivation during treatment, with resulting morbidity and mortality.”
To estimate the prevalence of the infections in patients with newly diagnosed cancers, investigators looked at a cohort of 3,051 patients with a cancer diagnosis made within the previous 120 days at nine academic medical centers and nine community oncology centers representing a total of 41 cancer clinics affiliated with the SWOG Cancer Research Network (formerly the Southwest Oncology Group).
The median patient age was 60.6 years. Female patients constitute 60.4% of the sample; 18.1% were black, and 18.3% were of Hispanic heritage.
Of 3,050 patients for whom HBV testing results were available, 6.5% (197) were positive for previous HBV infection, compared with an estimated U.S. population prevalence of 4.7%. In addition, 0.6% (19 patients) were found to have chronic HBV, compared with an estimated 0.3% US population prevalence.
HCV infections were detected in 2.4% (71 of 2990 patients), compared with an estimated population prevalence of 1.3%, and HIV infections were detected in 1.1%, compared with a background estimated population prevalence of 0.3%.
In all, 32 patients were diagnosed with viral infections by testing performed for the study, including 8 patients with chronic HBV, 22 with HCV, and 2 with HIV.
Additionally, the authors found that 4 patients with chronic HBV, 23 with HCV, and 7 with HIV had no identifiable risk factors.
The highest prevalence of infections occurred among patients with liver cancer, nonliver and noncolorectal cancers of the gastrointestinal tract, head and neck cancers, lung cancers, and prostate cancer. A finding of viral positivity changed the treatment plan in only 8% of all infected patients, however.
“Given that most HIV-infected patients in our study knew their viral status, the yield of universal HIV testing among patients with newly diagnosed cancer may likely be low. Although age-directed screening is recommended for HIV and HCV, uptake rates in primary care are variable and low overall,” Dr. Ramsey and his colleagues wrote.
The study was supported by grants from the National Cancer Institute. Dr. Ramsey and several co-authors reported receiving NCI grants, and multiple co-authors reported grants and/or consulting fees from various companies.

To estimate the prevalence of the infections in patients with newly diagnosed cancers, investigators looked at a cohort of 3,051 patients with a cancer diagnosis made within the previous 120 days at nine academic medical centers and nine community oncology centers representing a total of 41 cancer clinics affiliated with the SWOG Cancer Research Network (formerly the Southwest Oncology Group).
The median patient age was 60.6 years. Female patients constitute 60.4% of the sample; 18.1% were black, and 18.3% were of Hispanic heritage.
Of 3,050 patients for whom HBV testing results were available, 6.5% (197) were positive for previous HBV infection, compared with an estimated U.S. population prevalence of 4.7%. In addition, 0.6% (19 patients) were found to have chronic HBV, compared with an estimated 0.3% US population prevalence.
HCV infections were detected in 2.4% (71 of 2990 patients), compared with an estimated population prevalence of 1.3%, and HIV infections were detected in 1.1%, compared with a background estimated population prevalence of 0.3%.
In all, 32 patients were diagnosed with viral infections by testing performed for the study, including 8 patients with chronic HBV, 22 with HCV, and 2 with HIV.
Additionally, the authors found that 4 patients with chronic HBV, 23 with HCV, and 7 with HIV had no identifiable risk factors.
The highest prevalence of infections occurred among patients with liver cancer, nonliver and noncolorectal cancers of the gastrointestinal tract, head and neck cancers, lung cancers, and prostate cancer. A finding of viral positivity changed the treatment plan in only 8% of all infected patients, however.
“Given that most HIV-infected patients in our study knew their viral status, the yield of universal HIV testing among patients with newly diagnosed cancer may likely be low. Although age-directed screening is recommended for HIV and HCV, uptake rates in primary care are variable and low overall,” Dr. Ramsey and his colleagues wrote.
The study was supported by grants from the National Cancer Institute. Dr. Ramsey and several co-authors reported receiving NCI grants, and multiple co-authors reported grants and/or consulting fees from various companies.

Oncologists should consider testing all patients with newly diagnosed cancers for infection with the hepatitis B and C viruses, a multicenter team has recommended.
A prospective study of hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV infections among 3,051 patients with newly diagnosed cancers showed that 6.5% of patients tested positive for previous HBV and 0.6% had chronic HBV infection. In addition, 2.4% of patients were positive for HCV, and 1.1% for HIV infections, reported Scott D. Ramsey, MD, PhD, from the Fred Hutchinson Cancer Research Center in Seattle, and colleagues.
“Many patients had no known risk factors for infection, suggesting that current risk-based models for screening may be insufficient. Thus, we believe our results warrant consideration of universal testing of patients with newly diagnosed cancer for HBV and HCV infection, particularly if such an approach is shown to be cost effective,” they wrote in JAMA Oncology.
