Waves of retrotransposon expansion remodel genome organization and CTCF binding in multiple mammalian lineages.

CTCF-binding locations represent regulatory sequences that are highly constrained over the course of evolution. To gain insight into how these DNA elements are conserved and spread through the genome, we defined the full spectrum of CTCF-binding sites, including a 33/34-mer motif, and identified over five thousand highly conserved, robust, and tissue-independent CTCF-binding locations by comparing ChIP-seq data from six mammals. Our data indicate that activation of retroelements has produced species-specific expansions of CTCF binding in rodents, dogs, and opossum, which often functionally serve as chromatin and transcriptional insulators. We discovered fossilized repeat elements flanking deeply conserved CTCF-binding regions, indicating that similar retrotransposon expansions occurred hundreds of millions of years ago. Repeat-driven dispersal of CTCF binding is a fundamental, ancient, and still highly active mechanism of genome evolution in mammalian lineages.

British Society of Gastroenterology guidelines for the management of hepatocellular carcinoma in adults.

Deaths from the majority of cancers are falling globally, but the incidence and mortality from hepatocellular carcinoma (HCC) is increasing in the United Kingdom and in other Western countries. HCC is a highly fatal cancer, often diagnosed late, with an incidence to mortality ratio that approaches 1. Despite there being a number of treatment options, including those associated with good medium to long-term survival, 5-year survival from HCC in the UK remains below 20%. Sex, ethnicity and deprivation are important demographics for the incidence of, and/or survival from, HCC. These clinical practice guidelines will provide evidence-based advice for the assessment and management of patients with HCC. The clinical and scientific data underpinning the recommendations we make are summarised in detail. Much of the content will have broad relevance, but the treatment algorithms are based on therapies that are available in the UK and have regulatory approval for use in the National Health Service.

Routes to diagnosis for hepatocellular carcinoma patients: predictors and associations with treatment and mortality.

BACKGROUND: Hepatocellular carcinoma (HCC) incidence has increased rapidly, and prognosis remains poor. We aimed to explore predictors of routes to diagnosis (RtD), and outcomes, in HCC cases. METHODS: HCC cases diagnosed 2006-2017 were identified from the National Cancer Registration Dataset and linked to Hospital Episode Statistics and the RtD metric. Multivariable logistic regression was used to explore associations between RtD, diagnosis year, 365-day mortality and receipt of potentially curative treatment. RESULTS: 23,555 HCC cases were identified; 36.1% via emergency presentation (EP), 30.2% GP referral (GP), 17.1% outpatient referral, 11.0% two-week wait and 4.6% other/unknown routes. Odds of 365-day mortality was >70% lower via GP or OP routes than EP, and odds of curative treatment 3-4 times higher. Further adjustment for cancer/cirrhosis stage attenuated the associations with curative treatment. People who were older, female, had alcohol-related liver disease, or were more deprived, were at increased risk of an EP. Over time, diagnoses via EP decreased, and via GP increased. CONCLUSIONS: HCC RtD is an important predictor of outcomes. Continuing to reduce EP and increase GP and OP presentations, for example by identifying and regularly monitoring patients at higher risk of HCC, may improve stage at diagnosis and survival.

Hepatobiliary phenotypes of adults with alpha-1 antitrypsin deficiency.

OBJECTIVE: Alpha-1 antitrypsin deficiency (AATD) is a common, potentially lethal inborn disorder caused by mutations in alpha-1 antitrypsin (AAT). Homozygosity for the 'Pi*Z' variant of AAT (Pi*ZZ genotype) causes lung and liver disease, whereas heterozygous 'Pi*Z' carriage (Pi*MZ genotype) predisposes to gallstones and liver fibrosis. The clinical significance of the more common 'Pi*S' variant remains largely undefined and no robust data exist on the prevalence of liver tumours in AATD. DESIGN: Baseline phenotypes of AATD individuals and non-carriers were analysed in 482 380 participants in the UK Biobank. 1104 participants of a multinational cohort (586 Pi*ZZ, 239 Pi*SZ, 279 non-carriers) underwent a comprehensive clinical assessment. Associations were adjusted for age, sex, body mass index, diabetes and alcohol consumption. RESULTS: Among UK Biobank participants, Pi*ZZ individuals displayed the highest liver enzyme values, the highest occurrence of liver fibrosis/cirrhosis (adjusted OR (aOR)=21.7 (8.8-53.7)) and primary liver cancer (aOR=44.5 (10.8-183.6)). Subjects with Pi*MZ genotype had slightly elevated liver enzymes and moderately increased odds for liver fibrosis/cirrhosis (aOR=1.7 (1.2-2.2)) and cholelithiasis (aOR=1.3 (1.2-1.4)). Individuals with homozygous Pi*S mutation (Pi*SS genotype) harboured minimally elevated alanine aminotransferase values, but no other hepatobiliary abnormalities. Pi*SZ participants displayed higher liver enzymes, more frequent liver fibrosis/cirrhosis (aOR=3.1 (1.1-8.2)) and primary liver cancer (aOR=6.6 (1.6-26.9)). The higher fibrosis burden was confirmed in a multinational cohort. Male sex, age ≥50 years, obesity and the presence of diabetes were associated with significant liver fibrosis. CONCLUSION: Our study defines the hepatobiliary phenotype of individuals with the most relevant AATD genotypes including their predisposition to liver tumours, thereby allowing evidence-based advice and individualised hepatological surveillance.

Regional variations in hepatocellular carcinoma incidence, routes to diagnosis, treatment and survival in England.

BACKGROUND: Hepatocellular carcinoma (HCC) incidence, management and survival across England were examined to determine if geographical inequalities exist. METHOD: 15,468 HCC cases diagnosed 2010-2016 were included. Age-standardised incidence rates, net survival and proportions receiving potentially curative treatment and presenting through each route to diagnosis adjusted for age at diagnosis, sex and area-based deprivation quintile, were calculated overall and by Cancer Alliance. RESULTS: HCC incidence rates increased in men from 6.2 per 100,000 in 2010 to 8.8 in 2016, and in women from 1.5 to 2.2. The highest incidence rates, found in parts of the North of England and London, were nearly double the lowest. The adjusted proportion presenting as an emergency ranged 27-41% across Cancer Alliances. Odds increased with increasing deprivation quintile and age. Only one in five patients received potentially curative treatment (range 15-28%) and odds decreased with increasing deprivation and age. One-year survival in 2013-2016 ranged 38-53%. CONCLUSION: This population-based, nationwide analysis demonstrates clear differences in HCC incidence, management and survival across England. It highlights socioeconomic-associated variation and the need for improvement in early diagnosis and curative treatment of HCC. This research should assist policymakers, service providers and clinicians to identify regions where additional training, services and resources would be best directed.

A coordinated national UK liver transplant program response, prioritizing waitlist recipients with the highest need, provided excellent outcomes during the first wave of the COVID-19 pandemic.

INTRODUCTION: Healthcare provision has been severely affected by COVID-19, with specific challenges in organ transplantation. Here, we describe the coordinated response to, and outcomes during the first wave, across all UK liver transplant (LT) centers. METHODS: Several policy changes affecting the liver transplant processes were agreed upon. These included donor age restrictions and changes to offering. A "high-urgency" (HU) category was established, prioritizing only those with UKELD > 60, HCC reaching transplant criteria, and others likely to die within 90 days. Outcomes were compared with the same period in 2018 and 2019. RESULTS: The retrieval rate for deceased donor livers (71% vs. 54%; P < .0001) and conversion from offer to completed transplant (63% vs. 48%; P < .0001) was significantly higher. Pediatric LT activity was maintained; there was a significant reduction in adult (42%) and total (36%) LT. Almost all adult LT were super-urgent (n = 15) or HU (n = 133). We successfully prioritized those with highest illness severity with no reduction in 90-day patient (P = .89) or graft survival (P = .98). There was a small (5% compared with 3%; P = .0015) increase in deaths or removals from the waitlist, mainly amongst HU cohort. CONCLUSIONS: We successfully prioritized LT recipients in highest need, maintaining excellent outcomes, and waitlist mortality was only marginally increased.

The fate of indeterminate liver lesions: What proportion are precursors of hepatocellular carcinoma?

BACKGROUND: The natural history and incidence of hepatocellular carcinoma (HCC) arising from indeterminate liver lesions are not well described. We aimed to define the incidence of HCC in a cohort of patients undergoing surveillance by magnetic resonance imaging (MRI) and estimate any associations with incident HCC. METHODS: We performed a retrospective follow-up study, identifying MRI scans in which indeterminate lesions had been reported between January 2006 and January 2017. Subsequent MRI scan reports were reviewed for incident HCC arising from indeterminate lesions, data were extracted from electronic patient records and survival analysis performed to estimate associations with baseline factors. RESULTS: One hundred and nine patients with indeterminate lesions on MRI were identified. HCC developed in 19 (17%) patients over mean follow up of 4.6 years. Univariate Cox proportional hazards analysis found incident HCC to be significantly associated with baseline low platelet count (hazard ratio (HR) = 7.3 (95% confidence intervals (CI) 2.1-24.9), high serum alpha-fetoprotein level (HR = 2.7 (95% CI 1.0-7.1)) and alcohol consumption above fourteen units weekly (HR = 3.1 (95% CI 1.1-8.7)). Multivariate analysis, however, found that only low platelet count was independently associated with HCC (HR = 5.5 (95% CI 0.6-5.1)). CONCLUSIONS: HCC arises in approximately one fifth of indeterminate liver lesions over 4.6 years and is associated with a low platelet count at the time of first diagnosis of an indeterminate lesion. Incidence of HCC was more common in people with viral hepatitis and in those consuming > 14 units of alcohol per week. Our data may be used to support a strategy of enhanced surveillance in patients with indeterminate lesions.

Non-invasive alloimmune risk stratification of long-term liver transplant recipients.

BACKGROUND & AIMS: Management of long-term immunosuppression following liver transplantation (LT) remains empirical. Surveillance liver biopsies in combination with transcriptional profiling could overcome this challenge by identifying recipients with active alloimmune-mediated liver damage despite normal liver tests, but this approach lacks applicability. Our aim was to investigate the utility of non-invasive tools for the stratification of stable long-term survivors of LT, according to their immunological risk and need for immunosuppression. METHODS: We conducted a cross-sectional multicentre study of 190 adult LT recipients assessed to determine their eligibility to participate in an immunosuppression withdrawal trial. Patients had stable liver allograft function and had been transplanted for non-autoimmune non-replicative viral liver disease >3 years before inclusion. We performed histological, immunogenetic and serological studies and measured the intrahepatic transcript levels of an 11-gene classifier highly specific for T cell-mediated rejection (TCMR). RESULTS: In this cohort, 35.8% of patients harboured clinically silent fibro-inflammatory liver lesions (13.7% had mild damage and 22.1% had moderate-to-severe damage). The severity of liver allograft damage was positively associated with TCMR-related transcripts, class II donor-specific antibodies (DSAs), ALT, AST, and liver stiffness measurement (LSM), and negatively correlated with serum creatinine and tacrolimus trough levels. Liver biopsies were stratified according to their TCMR transcript levels using a cut-off derived from biopsies with clinically significant TCMR. Two multivariable prediction models, integrating ALT+LSM or ALT+class II DSAs, had a high discriminative capacity for classifying patients with or without alloimmune damage. The latter model performed well in an independent cohort of 156 liver biopsies obtained from paediatric liver recipients with similar inclusion/exclusion criteria. CONCLUSION: ALT, class II DSAs and LSM are valuable tools to non-invasively identify stable LT recipients without significant underlying alloimmunity who could benefit from minimisation of immunosuppression. LAY SUMMARY: A large proportion of liver transplant patients with normal liver tests have inflammatory liver lesions, which in 17% of cases are molecularly indistinguishable from those seen at the time of rejection. ALT, class II donor-specific antibodies and liver stiffness are useful in identifying patients with this form of subclinical rejection. We propose these markers as a useful tool to help clinicians determine if the immunosuppression administered is adequate.

Outcomes following SARS-CoV-2 infection in patients with chronic liver disease: An international registry study.

BACKGROUND & AIMS: Chronic liver disease (CLD) and cirrhosis are associated with immune dysregulation, leading to concerns that affected patients may be at risk of adverse outcomes following SARS-CoV-2 infection. We aimed to determine the impact of COVID-19 on patients with pre-existing liver disease, which currently remains ill-defined. METHODS: Between 25th March and 8th July 2020, data on 745 patients with CLD and SARS-CoV-2 (including 386 with and 359 without cirrhosis) were collected by 2 international registries and compared to data on non-CLD patients with SARS-CoV-2 from a UK hospital network. RESULTS: Mortality was 32% in patients with cirrhosis compared to 8% in those without (p <0.001). Mortality in patients with cirrhosis increased according to Child-Pugh class (A [19%], B [35%], C [51%]) and the main cause of death was from respiratory failure (71%). After adjusting for baseline characteristics, factors associated with death in the total CLD cohort were age (odds ratio [OR] 1.02; 1.01-1.04), Child-Pugh A (OR 1.90; 1.03-3.52), B (OR 4.14; 2.4-7.65), or C (OR 9.32; 4.80-18.08) cirrhosis and alcohol-related liver disease (OR 1.79; 1.03-3.13). Compared to patients without CLD (n = 620), propensity-score-matched analysis revealed significant increases in mortality in those with Child-Pugh B (+20.0% [8.8%-31.3%]) and C (+38.1% [27.1%-49.2%]) cirrhosis. Acute hepatic decompensation occurred in 46% of patients with cirrhosis, of whom 21% had no respiratory symptoms. Half of those with hepatic decompensation had acute-on-chronic liver failure. CONCLUSIONS: In the largest such cohort to date, we demonstrate that baseline liver disease stage and alcohol-related liver disease are independent risk factors for death from COVID-19. These data have important implications for the risk stratification of patients with CLD across the globe during the COVID-19 pandemic. LAY SUMMARY: This international registry study demonstrates that patients with cirrhosis are at increased risk of death from COVID-19. Mortality from COVID-19 was particularly high among patients with more advanced cirrhosis and those with alcohol-related liver disease.

Palliative Care for Patients with End-Stage Liver Disease on the Liver Transplant Waiting List: An International Systematic Review.

People with end-stage liver disease on the liver transplant waiting list have high symptom burden, which can successfully be addressed by specialist palliative care. Potential tensions with the perceived curative nature of liver transplant make delivering specialist palliative care challenging. This systematic review seeks to establish what is known on the impact of specialist palliative care for patients on liver transplant waiting lists, healthcare professionals' perspectives of providing specialist palliative care for this population, and uptake of advance care planning (ACP). Medline, Embase, and CINAHL were searched to May 5, 2020. Qualitative and quantitative findings were grouped together according to main relevant themes. Eight studies of mixed quality and mainly quantitative, were identified. Findings suggest early palliative care intervention improve patients' symptoms and prompt ACP conversations, but patients on the waiting list receive limited palliative care input. Liver physicians' lack of clarity on referral criteria and liver transplant patients' concerns of being abandoned, were reasons for reluctance to refer to specialist palliative care. They felt referral to specialist palliative care is appropriate only for patients receiving hospice or end of life care. Uptake and understanding of ACP and goals of care designation by patients is poor. This review found evidence of benefit of specialist palliative care for patients on liver transplant waiting lists, but found in a limited understanding of their role. Evidence is limited to studies from North America. Future research is needed to understand better how palliative care could be provided into this clinical environment.

Establishing Reliability Criteria for Liver ElastPQ Shear Wave Elastography (ElastPQ-SWE): Comparison Between 10, 5 and 3 Measurements.

PURPOSE: ElastPQ is a new elastography technique for non-invasive liver fibrosis staging. However, it does not have validated reliability criteria. We tested the reliability of a different number of measurements in patients with chronic liver disease and explored whether the application of quality criteria improves the diagnostic performance. MATERIALS AND METHODS: All patients underwent liver stiffness assessment (LSM) with ElastPQ and Fibroscan (F-TE). The mean, median, standard deviation (SD) and interquartile range (IQR) of 10, 5 and 3 measurements were retrospectively collected for each patient and compared to each other. Liver histology was available in a subset of patients. RESULTS: Overall, 400 patients met the inclusion criteria. Non-alcoholic fatty liver disease (NAFLD) was the most represented etiology (75 %), followed by primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH). The correlation of medians was significantly better between 10 and 5 measurements than between 10 and 3. The difference of medians was significant only in the comparison between 10 and 3 measurements. The correlation between ElastPQ and F-TE was equally good for 10 and 5 measurements and significantly improved after an IQR/median ≤ 30 % was applied. The diagnostic performance of ElastPQ was better with the median value of 10 and 5 measurements and improved if LSM values were obtained with IQR/M ≤ 30 %. CONCLUSION: The median value of 5 valid LSMs suffices for the reliable estimation of liver stiffness using ElastPQ. The quality criterion of IQR/M ≤ 30 % should also be followed when using this technique.

Improving Communication in Outpatient Consultations in People With Cirrhosis: The Development of a Question Prompt List (QPL).

BACKGROUND AND AIMS: Liver health professionals have difficulty discussing liver cirrhosis and its prognosis with patients and families. Question Prompt Lists (QPLs), which are evidence-based lists of "recommended questions," may improve communication but need to be designed specifically for the target population. This study aimed to develop and pilot a QPL for patients with cirrhosis. METHODS: A mixed-methods design in 3 phases. In phase 1 (item generation), potential questions for inclusion in the QPL were identified from 3 sources-a scoping literature review; an online survey; and interviews with patients, family members, and health professionals. In phase 2 (QPL construction), a multidisciplinary expert panel finalized the selection of questions and the format of the QPL. In phase 3 (pilot study), the QPL was assessed for acceptability and feasibility in a hepatology outpatient clinic population. RESULTS: From 258 topics initially identified, 30 questions were included in the first draft of the QPL. After review by a multidisciplinary expert panel including patients, the QPL was reduced to 22 questions. In the pilot study, 133/215 eligible patients consented to participate, although only 67/133 used the QPL in their clinic appointment. Among those who used the QPL, all questions were asked at least once. The most commonly asked question related to life expectancy. Most participants expressed support for the content of the QPL. CONCLUSIONS: A QPL, suitable for use in patients with liver cirrhosis attending hepatology outpatient clinics, has been developed and piloted. The QPL seems to be feasible to use and acceptable to patients and clinicians. Further work is needed to evaluate its effectiveness and to determine optimum delivery in clinical practice.

Independence of repressive histone marks and chromatin compaction during senescent heterochromatic layer formation.

The expansion of repressive epigenetic marks has been implicated in heterochromatin formation during embryonic development, but the general applicability of this mechanism is unclear. Here we show that nuclear rearrangement of repressive histone marks H3K9me3 and H3K27me3 into nonoverlapping structural layers characterizes senescence-associated heterochromatic foci (SAHF) formation in human fibroblasts. However, the global landscape of these repressive marks remains unchanged upon SAHF formation, suggesting that in somatic cells, heterochromatin can be formed through the spatial repositioning of pre-existing repressively marked histones. This model is reinforced by the correlation of presenescent replication timing with both the subsequent layered structure of SAHFs and the global landscape of the repressive marks, allowing us to integrate microscopic and genomic information. Furthermore, modulation of SAHF structure does not affect the occupancy of these repressive marks, nor vice versa. These experiments reveal that high-order heterochromatin formation and epigenetic remodeling of the genome can be discrete events.

Supportive and palliative care in people with cirrhosis: International systematic review of the perspective of patients, family members and health professionals.

BACKGROUND & AIMS: People with cirrhosis have unmet needs, which could benefit from a palliative care approach. Developing effective services needs to be based on evidence from those with personal experience. This review aims to explore; patient and family perspectives of perceived needs including communication; health professionals' perspectives on delivery of care and improving palliative care between specialities. METHODS: A literature search was conducted in Medline, Embase and CINAHL using key words reporting on the perspectives of patients with liver cirrhosis (18 years and over), family members or health professionals on the provision of care in liver cirrhosis. Study quality was assessed using the Mixed Methods Appraisal Tool. Qualitative and quantitative findings were grouped together according to the main relevant themes identified. RESULTS: Nineteen research studies predominantly from high-income Western countries were identified, with a total sample consisting of 1,413 patients, 31 family carers and 733 health professionals. Patients and family members had limited understanding of cirrhosis or its impact. They wanted better information about their disease, its treatment and help with psychological and practical needs. Health professionals had difficulty communicating about these issues to patients and their families. General practitioners left care predominantly to the liver clinicians, who lacked confidence to have discussions about prognosis or future care preferences. The role of palliative care was recognised as important in caring for this group through earlier integration with liver and community services. CONCLUSIONS: Health professionals need support to improve their communication with patients, to address patients' broader needs beyond medical treatment and to develop new models to improve palliative care coordination between different medical specialities. Future research should focus on developing communication aides, testing existing tools to identify suitable patients for supportive care and exploring robust ways of evaluating supportive care interventions, with more studies needed from middle- and low-income countries. Registration number: PROSPERO CRD42017064770. LAY SUMMARY: Patients and their families had a poor understanding of advanced liver disease and its impact on them. They need more information about the treatments they receive and how to get practical and psychological support. Liver specialists and GPs found it difficult to talk to patients and their families about the seriousness of advanced liver disease and the lack of healthcare options available to them if their condition gets worse. All doctors and nurses involved in the care of patients with advanced liver disease recognise that palliative and supportive care have an important role in improving patient care.

Utility of ElastPQ point-shear wave elastography in the work-up of patients with primary sclerosing cholangitis.

Background & Aims: Liver stiffness measurement (LSM) and spleen stiffness measurement (SSM) have been shown to be useful tools for assessing the risk of fibrosis and portal hypertension, respectively. However, data on the accuracy of LSM and SSM measured by point-shear wave elastography (pSWE) in patients affected by primary sclerosing cholangitis (PSC) are still lacking. Thus, we aimed to prospectively assess their performance in a cohort of patients with PSC. Methods: We determined the correlation between LSM assessed by a pSWE technique (ElastPQ) and by FibroScan-transient elastography (F-TE). Furthermore, we used receiver-operating characteristic curves and area under the curves (AUROC) to evaluate the performance of LSM by ElastPQ for the staging of fibrosis, using F-TE as a reference standard, and the performance of LSM and SSM by ElastPQ in predicting the presence of oesophageal varices (OVs). Results: One hundred and fifty-two patients with PSC (93 males [61.2%], mean age 46 ± 16 years) were prospectively recruited. ElastPQ and F-TE LSMs were available for all patients, while ElastPQ SSM was available in 109 (72%) patients of whom 35 underwent upper gastrointestinal endoscopy within 1 year of the ultrasound assessment. ElastPQ LSM showed an excellent correlation with F-TE (p <0.001, Spearman's 0.93; Lin's 0.86) and a good diagnostic accuracy for fibrosis staging along all stages of liver fibrosis (AUROCs 0.96, 0.97, 0.97 and 0.99 for fibrosis stages F≥1, F≥2, F≥3 and F=4, respectively), using F-TE as a surrogate of histological fibrosis. ElastPQ SSM showed a good diagnostic performance in predicting the presence of OVs at endoscopy. Conclusions: LSM and SSM by ElastPQ can be used as accurate tools for liver fibrosis risk assessment and fibrosis staging, as well as for predicting the presence of OVs in the work-up of patients with PSC. Impact and implications: Liver and spleen stiffness measurement (LSM and SSM, respectively) by ElastPQ point-shear wave elastography in patients with primary sclerosing cholangitis represent reliable and reproducible tools for non-invasively staging the severity of liver disease and stratifying patients according to their risk of developing liver-related outcomes. In particular, LSM shows good accuracy for staging liver fibrosis and therefore detecting those patients at high risk of having compensated advanced chronic liver disease who require close monitoring. SSM seems to be promising to detect the risk of portal hypertension and therefore of oesophageal varices, enabling the triaging of patients who really need to undergo a screening endoscopy.

Cost of hepatocellular carcinoma to the national health service in England: a registry-based analysis.

OBJECTIVE: Hepatocellular carcinoma (HCC) incidence in the UK trebled between 1997 and 2017. With increasing numbers requiring treatment, understanding the likely impact on healthcare budgets can inform service planning and commissioning. The aim of this analysis was to use existing registry data to describe the direct healthcare costs of current treatments for HCC and estimate the impact on National Health Service (NHS) budgets. DESIGN: A retrospective data analysis based on the National Cancer Registration and Analysis Service cancer registry informed a decision-analytic model for England comparing patients by cirrhosis compensation status and those on palliative or curative treatment pathways. Potential cost drivers were investigated by undertaking a series of one-way sensitivity analyses. RESULTS: Between 1 January 2010 and 31 December 2016, 15 684 patients were diagnosed with HCC. The median cost per patient over 2 years was £9065 (IQR: £1965 to £20 491), 66% did not receive active therapy. The cost of HCC treatment for England over 5 years was estimated to be £245 million. CONCLUSION: The National Cancer Registration Dataset and linked data sets have enabled a comprehensive analysis of the resource use and costs of secondary and tertiary healthcare for HCC, providing an overview of the economic impact to the NHS England of treating HCC.

Do screening tools assess palliative care needs and 12-month mortality in patients admitted to hepatology in-patient wards?

Background: Many liver patients have unmet palliative care needs, but liver clinicians are unclear whom to refer to specialist palliative care (SPC). The Supportive and Palliative Care Indicator Tool (SPICT) and the Bristol Prognostic Screening Tool (BPST) could help identify suitable patients, but neither has been tested for this role. This study evaluated their role as screening tools for palliative care needs and for predicting 12-month mortality. Methods: A case note review of hepatology in-patients, who were not peritransplant and post-transplant status, was conducted in one tertiary unit. Main outcomes were clinical judgement of need for SPC referral, BPST scores, SPICT attribution of caseness and 12-month survival status. Discriminatory ability of tools was assessed using sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the receiver operating characteristic (AUROC) curve. Results: 117 medical notes were reviewed for survival analysis, 47 of which were additionally assessed for suitability for SPC referral, using clinical judgement. SPICT (sensitivity=93%; PPV=93%; AUROC=0.933) and BPST (sensitivity=59%, PPV=79%, AUROC=0.693) demonstrated excellent and good performance, respectively, in predicting patients' need for SPC referral. SPICT and BPST only had moderate ability at predicting death at 12 months (PPV: 54% and 56%, respectively). Conclusion: SPICT and BPST show potential as screening tools for identifying patients for referral to SPC. Further work is needed to determine how to implement these tools in a clinical setting.
