Early Survivorship After Liver Transplantation: A Qualitative Study Identifying Challenges in Recovery From the Patient and Caregiver Perspective.

Survivorship after liver transplantation (LT) is a novel concept providing a holistic view of the arduous recovery experienced after transplantation. We explored components of early survivorship including physical, emotional, and psychological challenges to identify intervention targets for improving the recovery process of LT recipients and caregivers. A total of 20 in-person interviews were conducted among adults 3 to 6 months after LT. Trained qualitative research experts conducted interviews, coded, and analyzed transcripts to identify relevant themes and representative quotes. Early survivorship comprises overcoming (1) physical challenges, with the most challenging experiences involving mobility, driving, dietary modifications, and medication adherence, and (2) emotional and psychological challenges, including new health concerns, financial worries, body image/identity struggles, social isolation, dependency issues, and concerns about never returning to normal. Etiology of liver disease informed survivorship experiences including some patients with hepatocellular carcinoma expressing decisional regret or uncertainty in light of their post-LT experiences. Important topics were identified that framed LT recovery including setting expectations about waitlist experiences, hospital recovery, and ongoing medication requirements. Early survivorship after LT within the first 6 months involves a wide array of physical, emotional, and psychological challenges. Patients and caregivers identified what they wish they had known prior to LT and strategies for recovery, which can inform targeted LT survivorship interventions.

Review article: new therapeutic interventions for advanced hepatocellular carcinoma.

BACKGROUND: Advanced hepatocellular carcinoma (HCC) portends a poor prognosis; however recent advances in first-line and second-line treatment options should yield significant improvements in survival. AIM: To summarize the evolving landscape of treatment options for patients with advanced HCC. METHODS: We reviewed published clinical trials conducted in patients with advanced HCC published in PubMed or presented at national conferences. RESULTS: Sorafenib was approved for treatment of unresectable HCC in 2007 and remained the only therapy with proven survival benefit in advanced HCC for several years. Lenvatinib, another tyrosine-kinase inhibitor, was recently shown to have non-inferior survival vs sorafenib and is another first-line treatment option. The tyrosine-kinase inhibitors, regorafenib and cabozantinib, were shown to significantly improve survival in the second-line setting after sorafenib failure. Ramucirumab, a VEGF inhibitor, can also improve survival in the second-line setting among patients with AFP ≥ 400 ng/dL. Phase II data highlight potential durable objective responses with immune checkpoint inhibitors, prompting conditional FDA approval of nivolumab and pembrolizumab in the second-line setting; however, recent phase III data have failed to demonstrate improved survival compared to other treatment options. Ongoing trials are evaluating combination immune checkpoint inhibitor and immune checkpoint inhibitors with tyrosine-kinase inhibitors or VEGF inhibitors in hopes of further increasing objective responses and overall survival in this patient population. CONCLUSION: There are several first-line and second-line therapeutic options available for patients with advanced HCC. Further studies are needed to determine how best to select between and sequence the growing number of therapeutic options.

Observational registry of sorafenib use in clinical practice across Child-Pugh subgroups: The GIDEON study.

BACKGROUND & AIMS: GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib) is a prospective, observational registry study evaluating the safety of sorafenib and treatment practices in hepatocellular carcinoma patients. This large global database allowed for assessment of the use and tolerability of sorafenib in patients with liver dysfunction. METHODS: Baseline characteristics and medical/treatment history were collected in patients for whom a decision to treat with sorafenib had been made. Adverse event, dosing, and outcomes data were collected during follow-up. RESULTS: In the overall safety population (n=3202), 1968 patients (61%) had Child-Pugh A status and 666 (21%) had Child-Pugh B. The majority of Child-Pugh A (72%) and Child-Pugh B (70%) patients received an initial sorafenib dose of 800mg, consistent with the label, and dose reduction rates were 40% and 29%, respectively. The type and incidence of adverse events were generally consistent across Child-Pugh subgroups. The incidence of drug-related adverse events leading to discontinuation was similar between Child-Pugh A and Child-Pugh B patients (17% and 21%). In the intent-to-treat population (n=3213), median overall survival (months [95% confidence interval]) was longer in Child-Pugh A patients (13.6 [12.8-14.7]) compared with Child-Pugh B patients (5.2 [4.6-6.3]). CONCLUSIONS: In clinical practice, the safety profile of sorafenib appeared to be consistent across Child-Pugh A and Child-Pugh B patients. Findings suggest sorafenib may be safely used in some Child-Pugh B patients and indicate the importance of careful patient evaluation when making treatment decisions. LAY SUMMARY: The GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib) study is a large prospective registry of patients with liver cancer who were treated with sorafenib. The aims were to evaluate the safety and tolerability of sorafenib among those in which the liver was not functioning properly. The study showed that the safety profile of sorafenib was consistent across patients with preserved liver function and those in which the liver was not functioning properly, and therefore, suggesting that sorafenib may be a valid treatment for some patients with liver impairment.

Regional differences in sorafenib-treated patients with hepatocellular carcinoma: GIDEON observational study.

BACKGROUND & AIMS: Treatment approaches for hepatocellular carcinoma (HCC) vary across countries, but these differences and their potential impact on outcomes have not been comprehensively assessed. Data from the multinational GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) registry evaluated differences in patient characteristics, practice patterns and outcomes in HCC across geographical regions in patients who received sorafenib. METHODS: GIDEON is a non-randomised, observational registry study conducted in 39 countries across five global regions. HCC patients in whom a decision to treat with sorafenib was made in clinical practice and according to local practices were included. RESULTS: 3202 patients were evaluable for safety analysis: Asia-Pacific (n = 928), Japan (n = 508), Europe (n = 1113), USA (n = 563) and Latin America (n = 90). Patients in Japan had earlier-stage disease at initial diagnosis compared with patients in other regions (Barcelona Clinic Liver Cancer stage A; 43.7% vs 9.1-24.3%). Use of locoregional therapies before sorafenib, including transarterial chemoembolisation, was more common in Japan (84.4%) and Asia-Pacific (67.2%) compared with the USA (49.4%) and Europe (43.5%). Treatment patterns with respect to sorafenib also differed, with a shorter duration of treatment reported in the USA and Asia-Pacific. Time from initial diagnosis to death was longer in Japan compared with other regions (median, 79.6 months vs 14.8-25.0 months). CONCLUSIONS: Data from GIDEON highlight regional variations in the management of HCC and patient outcomes. Greater standardisation of management may help optimise outcomes for HCC patients.

TACE Treatment in Patients with Sorafenib-treated Unresectable Hepatocellular Carcinoma in Clinical Practice: Final Analysis of GIDEON.

PURPOSE: To evaluate transarterial chemoembolization (TACE) use prior to and concomitantly with sorafenib in patients with unresectable hepatocellular carcinoma (HCC) across different global regions. MATERIALS AND METHODS: GIDEON is an observational registry study of more than 3000 HCC patients. Patients with histologically, cytologically, or radiographically diagnosed HCC, and for whom a decision had been made to treat with sorafenib, were eligible. Patients were enrolled into the registry from 39 countries beginning in January 2009, with the last patient follow-up in April 2012. Detailed data on treatment history, treatment patterns, adverse events, and outcomes were collected. All treatment decisions were at the discretion of the treating physicians. Documented approval from local ethics committees was obtained, and all patients provided signed informed consent. Descriptive statistics, including minimum, median, and maximum, were calculated for metric data, and frequency tables for categorical data. Kaplan-Meier estimates with 95% confidence intervals were calculated for survival end points. RESULTS: A total of 3202 patients were eligible for safety analysis, of whom 2631 (82.2%) were male. Median age was 62 years (range, 15-98 years). A total of 1511 (47.2%) patients underwent TACE prior to sorafenib; 325 (10.1%) underwent TACE concomitantly. TACE prior to sorafenib was more common in Japan and Asia-Pacific compared with all other regions (362 [71.3%] and 560 [60.3%] vs 12-209 [13.3%-37.1%]). Adverse events were reported in 2732 (85.3%) patients overall, with no notable differences in the incidence of adverse events, regardless of TACE treatment history. Overall survival was 12.7 months in prior-TACE patients, 9.2 months in non-prior-TACE patients, 21.6 months in concomitant-TACE patients, and 9.7 months in non-concomitant-TACE patients. CONCLUSION: Global variation exists in TACE use in sorafenib-treated HCC patients. The combination of TACE with sorafenib appears to be a well-tolerated and viable therapeutic approach.

Extending survival with the use of targeted therapy in the treatment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide, with an increasing incidence projected through 2020. HCC is the third-leading cause of cancer-related deaths worldwide. Management of HCC is complicated by the fact that these patients also have a cirrhotic or otherwise diseased liver that led to the tumorigenesis. To aid in treatment decisions, several staging systems have been developed. In the United States, the Barcelona Clinic Liver Cancer (BCLC) system has emerged as the predominant system, owing to its concomitant consideration of tumor stage, liver function, and physical status, as well as its ability to identify patients with early-stage disease who may benefit from curative therapies. Surveillance for HCC has gained increasing importance in light of several studies demonstrating both clinical and cost benefits. Once HCC is detected and diagnosed, it is usually managed according to its BCLC stage. Patients with early-stage disease often benefit from potentially curative therapies, such as surgical resection and liver transplantation. Often, local ablation such as radiofrequency ablation or percutaneous alcohol injection can be used not only as an effective treatment, but also as a bridge therapy to maintain the status of patients on the liver transplant list. Intermediate-stage patients are typically treated with transarterial chemoembolization, but have a high rate of disease recurrence. The multikinase inhibitor sorafenib is the only treatment option approved for patients with advanced-stage HCC. Sorafenib has demonstrated a significant survival advantage in these patients. Numerous studies have evaluated other novel targeted therapies in this setting, but none have shown superiority to sorafenib.

Efficacy and safety of sorafenib in patients with advanced hepatocellular carcinoma: subanalyses of a phase III trial.

BACKGROUND & AIMS: The Sorafenib Hepatocellular Carcinoma (HCC) Assessment Randomized Protocol (SHARP) trial demonstrated that sorafenib improves overall survival and is safe for patients with advanced HCC. In this trial, 602 patients with well-preserved liver function (>95% Child-Pugh A) were randomized to receive either sorafenib 400mg or matching placebo orally b.i.d. on a continuous basis. Because HCC is a heterogeneous disease, baseline patient characteristics may affect individual responses to treatment. In a comprehensive series of exploratory subgroup analyses, data from the SHARP trial were analyzed to discern if baseline patient characteristics influenced the efficacy and safety of sorafenib. METHODS: Five subgroup domains were assessed: disease etiology, tumor burden, performance status, tumor stage, and prior therapy. Overall survival (OS), time to progression (TTP), disease control rate (DCR), and safety were assessed for subgroups within each domain. RESULTS: Subgroup analyses showed that sorafenib consistently improved median OS compared with placebo, as reflected by hazard ratios (HRs) of 0.50-0.85, similar to the complete cohort (HR=0.69). Sorafenib also consistently improved median TTP (HR, 0.40-0.64), except in HBV-positive patients (HR, 1.03), and DCR. Results are limited by small patient numbers in some subsets. The most common grade 3/4 adverse events included diarrhea, hand-foot skin reaction, and fatigue; the incidence of which did not differ appreciably among subgroups. CONCLUSIONS: These exploratory subgroup analyses showed that sorafenib consistently improved median OS and DCR compared with placebo in patients with advanced HCC, irrespective of disease etiology, baseline tumor burden, performance status, tumor stage, and prior therapy.

Role of liver transplantation in the treatment of cholangiocarcinoma.

Cholangiocarcinoma is a rare malignancy arising from the bile duct epithelium with a grim prognosis. Although complete resection may be curative, it is feasible only in a minority of cases owing to local extension of the tumor. Early experiences with liver transplantation were discouraging, given the high rates of tumor recurrence and poor patient survival. Trials with aggressive transplantation methods and adjuvant chemotherapy did not yield significantly better outcomes. Recently, stringent patient selection and neoadjuvant chemoradiation have yielded promising results with 5-year survival rates as high as 76%. Factors associated with recurrence after transplantation include advanced age, history of cholecystectomy, elevated serum glycoprotein cancer antigen 19-9 level, a discreet mass on imaging and an interval from enrollment to transplant greater than 100 days.
