Palliative Care and Hospice Interventions in Decompensated Cirrhosis and Hepatocellular Carcinoma: A Rapid Review of Literature

Palliative care in terminally ill advanced chronic liver disease patients

While mortality rates from advanced chronic liver disease (ACLD) are rapidly increasing, patients with an advanced disease stage have a comparable or even higher symptom burden than those with other life-limiting diseases. Although evidence is limited there is increasing recognition of the need to improve care for patients with ACLD; however, there are many limiting factors to providing good palliative care for these patients, including unpredictable disease progression, the misconception of palliative care and end of life care as being equivalent, a lack of confidence in prescribing medication and a lack of time and resources. Health professionals working with these patients need to develop the skills to ensure effective palliative care, while referral to specialized palliative care centers should be reserved for patients with complex needs. Basic palliative care, along with active disease management, is best delivered by the treating hepatologists. This includes discussions about disease progression and advance care planning, alongside the active management of disease complications. Liver disease is closely associated with significant social, psychological, and financial burdens for patients and their caregivers. Strategies to engage the discussion in multidisciplinary teams early in disease progression help to ensure addressing these issues proactively. This review summarizes the evidence on palliative care for patients with ACLD, provides examples of current best practice and offers suggestions on how disease-modifying and palliative care can coexist, to ensure that patients do not miss opportunities for quality of life improving interventions.

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.

Overexpression of wild-type HRAS drives non-alcoholic steatohepatitis to hepatocellular carcinoma in mice

Hepatocellular carcinoma (HCC), a prevalent solid carcinoma of significant concern, is an aggressive and often fatal disease with increasing global incidence rates and poor therapeutic outcomes. The etiology and pathological progression of non-alcoholic steatohepatitis (NASH)-related HCC is multifactorial and multistage. However, no single animal model can accurately mimic the full NASH-related HCC pathological progression, posing considerable challenges to transition and mechanistic studies. Herein, a novel conditional inducible wild-type human HRAS overexpressed mouse model (HRAS-HCC) was established, demonstrating 100% morbidity and mortality within approximately one month under normal dietary and lifestyle conditions. Advanced symptoms of HCC such as ascites, thrombus, internal hemorrhage, jaundice, and lung metastasis were successfully replicated in mice. In-depth pathological features of NASH- related HCC were demonstrated by pathological staining, biochemical analyses, and typical marker gene detections. Combined murine anti-PD-1 and sorafenib treatment effectively prolonged mouse survival, further confirming the accuracy and reliability of the model. Based on protein-protein interaction (PPI) network and RNA sequencing analyses, we speculated that overexpression of HRAS may initiate the THBS1-COL4A3 axis to induce NASH with severe fibrosis, with subsequent progression to HCC. Collectively, our study successfully duplicated natural sequential progression in a single murine model over a very short period, providing an accurate and reliable preclinical tool for therapeutic evaluations targeting the NASH to HCC continuum.

Advanced hepatocellular carcinoma and palliative care: a scoping review

BACKGROUND

Patients with advanced hepatocellular carcinoma (HCC) have specific palliative care needs owing to the influence of the disease on abdominal pain, jaundice, bleeding, appetite, ascites, liver function and hepatic encephalopathy. This research would help develop care models and identify knowledge gaps in the field.

AIMS

To identify the palliative care needs and experiences of patients with advanced HCC.

METHODS

CINAHL, EMBASE and MEDLINE were used to search English literature from January 1998 to March 2022 for 'Palliative care' and 'Hepatocellular cancer' using precise inclusion and exclusion criteria.

RESULTS

The retrieves identified 2710 records, including 33 studies used in our research. Two additional studies were grey items. Among 35 studies, 13 studies were performed in Asia, 11 studies in North America, 8 studies in Europe and 3 studies in Australia. Quantitative investigations were mostly descriptive or observational. Eight studies were conducted on a national scale, while two were in specific regions. 20 studies were conducted by a single institution. 22 studies focused only on patients, 2 on family caregivers and 2 on healthcare professionals. 2 more studies concentrated on patients and family caregivers, while 6 concentrated on patients and healthcare professionals.

CONCLUSIONS

This scoping study illustrates the complexity of advanced HCC treatment and challenges in modern healthcare systems. Formulating appropriate referral criteria, integrating and coordinating care, and assessing care contents are crucial. To enhance the treatment of patients with advanced HCC, it is important to understand the relationships between research and service design across teams, disciplines and care settings.

Current Medical Treatment for Alcohol-Associated Liver Disease

Alcohol-associated liver disease is one of the main causes of chronic liver disease. It comprises a clinical-histologic spectrum of presentations, from steatosis, steatohepatitis, to different degrees of fibrosis, including cirrhosis and severe necroinflammatory disease, called alcohol-associated hepatitis. In this focused update, we aim to present specific therapeutic interventions and strategies for the management of alcohol-associated liver disease. Current evidence for management in all spectra of manifestations is derived from general chronic liver disease recommendations, but with a higher emphasis on abstinence and nutritional support. Abstinence should comprise the treatment of alcohol use disorder as well as withdrawal syndrome. Nutritional assessment should also consider the presence of sarcopenia and its clinical manifestation, frailty. The degree of compensation of the disease should be evaluated, and complications, actively sought. The most severe acute form of this disease is alcohol-associated hepatitis, which has high mortality and morbidity. Current treatment is based on corticosteroids that act by reducing immune activation and blocking cytotoxicity and inflammation pathways. Other aspects of treatment include preventing and treating hepatorenal syndrome as well as preventing infections although there is no clear evidence as to the benefit of probiotics and antibiotics in prophylaxis. Novel therapies for alcohol-associated hepatitis include metadoxine, interleukin-22 analogs, and interleukin-1-beta antagonists. Finally, granulocyte colony-stimulating factor, microbiota transplantation, and gut-liver axis modulation have shown promising results. We also discuss palliative care in advanced alcohol-associated liver disease.

Trends of Clinical Outcomes of Patients with Advanced Hepatocellular Carcinoma Treated with First-Line Sorafenib in Randomized Controlled Trials

BACKGROUND

Sorafenib has consistently served as the control arm in multiple randomized clinical trials (RCTs) evaluating novel therapies for advanced hepatocellular carcinoma (HCC) for more than a decade. Analyzing trends in clinical outcomes of patients treated with sorafenib for the same indication over time offers the opportunity for unique insight into the evolution of clinical trial conduct and potential non-drug factors impacting outcomes.

METHODS

We identified RCTs in patients with treatment-naïve advanced HCC where sorafenib was compared to another systemic therapy or placebo. We extracted trial-level demographic, clinicopathologic, and outcome data (overall survival [OS], progression-free survival [PFS], objective response rate [ORR], and duration of therapy). Sample-weighted linear regression was used to identify temporal trends with significance set at p ≤ 0.05.

RESULTS

Sixteen RCTs (9 phase III and 7 phase II) enrolling 4,086 patients treated with sorafenib were included in the analysis. Included trials enrolled patients from 2005 to 2019. OS has significantly improved by 4.5 months from 2005 to 2019 (p = 0.048) over time. Thirteen studies provided data on PFS using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, with no significant change over time (p = 0.69). ORR assessed by RECIST 1.1 has significantly improved by 6.0% over time (p = 0.003). Median duration of therapy with sorafenib has decreased by 53% since the enrollment of the first clinical trial in 2005, from 23.1 weeks to 12.2 weeks (p = 0.0037). There was no significant change in patient demographics were identified over time to explain the OS findings.

CONCLUSION

The median OS of patients with advanced HCC treated with sorafenib has improved significantly over 15 years. At the same time, the median duration of therapy with sorafenib has decreased. The reason for these findings was not explained by changing demographics of patients enrolled in these trials and has implications for ongoing clinical trials.

Developing Priorities for Palliative Care Research in Advanced Liver Disease: A Multidisciplinary Approach

Individuals with advanced liver disease (AdvLD), such as decompensated cirrhosis (DC) and hepatocellular carcinoma (HCC), have significant palliative needs. However, little research is available to guide health care providers on how to improve key domains related to palliative care (PC). We sought to identify priority areas for future research in PC by performing a comprehensive literature review and conducting iterative expert panel discussions. We conducted a literature review using search terms related to AdvLD and key PC domains. Individual reviews of these domains were performed, followed by iterative discussions by a panel consisting of experts from multiple disciplines, including hepatology, specialty PC, and nursing. Based on these discussions, priority areas for research were identified. We identified critical gaps in the available research related to PC and AdvLD. We developed and shared five key priority questions incorporating domains related to PC. Conclusion: Future research endeavors focused on improving PC in AdvLD should consider addressing the five key priorities areas identified from literature reviews and expert panel discussions.

A closer look at quality of life in the hepatocellular carcinoma literature

PURPOSE

Adults with hepatocellular carcinoma (HCC) have a high symptom burden. Their quality of life (QOL) has been shown to be significantly impacted by both the disease and its treatment, adding to the high symptom burden that these patients experience. The primary aims of this paper are as follows: (1) to identify how QOL is being defined in HCC literature and (2) to identify how QOL is being measured in the HCC literature using Ferrell's model of QOL.

METHODS

A systematic review was completed of relevant studies published after 2014, using PubMed, CINHAL, and PsycInfo. Relevant studies were reviewed by 2 reviewers using PRISMA guidelines.

RESULTS

From a total of 1312 papers obtained in the initial database search, 30 met inclusion criteria and are included in this review. From the included articles, 10% included a definition of QOL and 3% addressed the spiritual domain of QOL. Majority of study participants were in the early stage of HCC, though the majority of adults with HCC are diagnosed in the advanced stage. Only 3% of included studies included greater than 22% population of advanced stage of HCC.

CONCLUSION

The results of this systematic review demonstrate the need for future research into QOL in the advanced stage of QOL. It also identified gap in the literature concerning the definition of QOL in HCC and the spiritual domain of QOL in HCC.

Underutilization of Hospice in Inpatients with Cirrhosis: The NACSELD Experience

BACKGROUND

Little is known about patients discharged to hospice following hospitalization for complications of cirrhosis.

AIM

We sought to understand the current pattern of hospice utilization in patients with cirrhosis by evaluating the North American Consortium for the Study of End-stage Liver Disease (NACSELD) cohort.

METHODS

Patients with cirrhosis from 14 tertiary-care hepatology centers across North America non-electively hospitalized and prospectively enrolled were evaluated. Exclusion criteria included HIV infection, transplantation or non-hepatic malignancy. Random computer-based propensity score matching was undertaken in a 1:2 ratio based on admission MELD score ± 3 points.

RESULTS

Totally, 2718 patients were enrolled, 5% (N = 132) were discharged to hospice, 6% (N = 171) died, and the rest were discharged alive. Patients discharged to hospice were older (60 vs. 57 years, p = 0.04), less likely to have had SBP (13% vs. 28%, p = 0.002) and be listed for liver transplantation (11% vs. 26%, p = 0.0007). Features, on multivariable modeling, associated with increased probability of discharge to hospice as opposed to being discharged alive: grade-3-4 hepatic encephalopathy, a higher Child-Turcotte-Pugh (CTP) score, and a higher discharge serum creatinine; however, a higher serum sodium, being listed for transplant and being prescribed rifaximin or a statin were protective from hospice discharge.

CONCLUSION

Patients with more advanced liver disease, hepatic encephalopathy, renal dysfunction, and those not candidates for liver transplantation were more likely to be discharged to hospice. However, in this sick multinational cohort of cirrhotic inpatients, it seems that hospice is markedly underutilized (5%) since 25% of patients not discharged to hospice died within 6 months.

Health Care Utilization and End-of-Life Care Outcomes for Patients With Decompensated Cirrhosis Based on Transplant Candidacy

CONTEXT

Patients with decompensated cirrhosis have high rates of health care utilization at end of life (EOL). However, the impact of transplant candidacy on intensity of EOL care is currently unknown.

OBJECTIVES

To assess the relationship between transplant candidacy and intensity of EOL care in the last year of life in an ambulatory cohort of patients with decompensated cirrhosis.

METHODS

We performed a retrospective analysis of 230 patients with decompensated cirrhosis who were evaluated for liver transplantation in a large health care system between 1/1/2010 and 12/31/2017 and died by 6/20/2018. We compared health care utilization in the last year of life and EOL care outcomes between transplant-listed (n = 133) and nonlisted (n = 97) patients. We examined predictors of palliative and hospice care utilization using multivariate logistic regression.

RESULTS

During the last year of life, patients had a median of three hospitalizations (IQR 2-5) and spent a median of 31 days (IQR 16-49) in the hospital. In all, 80% of patients died in the hospital, with 70% dying in the intensive care unit. The majority (70.0%) received a life-sustaining procedure (mechanical ventilation, renal replacement therapy, or cardiopulmonary resuscitation) during their terminal hospitalization, which did not differ between transplant-listed and nonlisted patients (74.4% vs. 63.9%, P = 0.09). Transplant-listed patients had lower odds of receiving specialty palliative care (odds ratio 0.43, P = 0.005). Patients with hepatocellular carcinoma had higher odds of receiving hospice care (odds ratio 2.03, P = 0.049).

CONCLUSION

Patients with decompensated cirrhosis had intensive health care utilization during their last year of life regardless of transplant candidacy. Further work is needed to optimize their EOL care, particularly for patients who are ineligible for transplantation.

IDentification of patients in need of general and specialised PALLiative care (ID-PALL©): item generation, content and face validity of a new interprofessional screening instrument

BACKGROUND

Early identification of patients requiring palliative care is a major public health concern. A growing number of instruments exist to help professionals to identify these patients, however, thus far, none have been thoroughly assessed for criterion validity. In addition, no currently available instruments differentiate between patients in need of general vs. specialised palliative care, and most are primarily intended for use by physicians. This study aims to develop and rigorously validate a new interprofessional instrument allowing identification of patients in need of general vs specialised palliative care.

METHODS

The instrument development involved four steps: i) literature review to determine the concept to measure; ii) generation of a set of items; iii) review of the initial set of items by experts to establish the content validity; iv) administration of the items to a sample of the target population to establish face validity. We conducted a Delphi process with experts in palliative care to accomplish step 3 and sent a questionnaire to nurses and physicians non-specialised in palliative care to complete step 4. The study was conducted in the French and Italian-speaking regions of Switzerland. An interdisciplinary committee of clinical experts supervised all steps.

RESULTS

The literature review confirmed the necessity of distinguishing between general and specialised palliative care needs and of adapting clinical recommendations to these different needs. Thirty-six nurses and physicians participated in the Delphi process and 28 were involved in the face validity assessment. The Delphi process resulted in two lists: a 7-item list to identify patients in need of general PC and an 8-item list to identify specialised PC needs. The content and face validity were deemed to be acceptable by both the expert and target populations.

CONCLUSION

This instrument makes a significant contribution to the identification of patients with palliative care needs as it has been designed to differentiate between general and specialised palliative care needs. Moreover, diagnostic data is not fundamental to the use of the instrument, thus facilitating its use by healthcare professionals other than physicians, in particular nurses. Internal and criterion validity assessments are ongoing and essential before wider dissemination of the instrument.

Palliative care in liver disease: what does good look like?

The mortality rate from chronic liver disease in the UK is rising rapidly, and patients with advanced disease have a symptom burden comparable to or higher than that experienced in other life-limiting illnesses. While evidence is limited, there is growing recognition that care of patients with advanced disease needs to improve. Many factors limit widespread provision of good palliative care to these patients, including the unpredictable trajectory of chronic liver disease, the misconception that palliative care and end-of-life care are synonymous, lack of confidence in prescribing and lack of time and resources. Healthcare professionals managing these patients need to develop the skills to ensure effective delivery of core palliative care, with referral to specialist palliative care services reserved for those with complex needs. Core palliative care is best delivered by the hepatology team in parallel with active disease management. This includes ensuring that discussions about disease trajectory and advance care planning occur alongside active management of disease complications. Liver disease is strongly associated with significant social, psychological and financial hardships for patients and their carers; strategies that involve the wider multidisciplinary team at an early stage in the disease trajectory help ensure proactive management of such issues. This review summarises the evidence supporting palliative care for patients with advanced chronic liver disease, presents examples of current best practice and provides pragmatic suggestions for how palliative and disease-modifying care can be run in parallel, such that patients do not miss opportunities for interventions that improve their quality of life.
