RESUMO

Purpose: Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare primary liver malignancy often diagnosed at advanced stages. While there are limited data on the efficacy of specific agents, we aim to report outcomes of patients treated with systemic therapies and explore prognostic factors. Patients and Methods: Medical records of patients treated between 2010 and 2022 were reviewed. Treatments were defined after multidisciplinary assessment. Descriptive statistics were used for baseline demographics. Time-to-event outcomes were estimated using the Kaplan-Meier method, compared by log-rank and adjusted by a regression model. Radiomic features (including size, shape, and texture) of the primary lesion were extracted and dimensionality reduced. An unsupervised Gaussian Mixture Model (GMM) clustering was performed, and survival was compared between clusters. Results: We identified 23 patients: 12 males, with a median age of 23.6 years. At diagnosis, 82.6% had metastases, most frequently to the lungs (39.1%), lymph nodes (39.1%), and peritoneum (21.7%). Patients received a median of three lines (1-8) of treatment, including different regimens. Sorafenib (39.1%), capecitabine (30.4%), and capecitabine/interferon (13%) were the most used first-line regimens. The median time-to-failure was 3.8 months (95% CI: 3.2-8.7). Capecitabine + interferon (42.1%) and platinum combinations (39.1%) were the most used second-line regimens, with a time-to-failure of 3.5 months (95% CI: 1.5-11.6). Median overall survival was 26.7 months (95% CI: 15.1-40.4). A high baseline neutrophil-to-lymphocyte ratio (NLR) was associated with worse survival (p=0.02). Radiomic features identified three clusters, with one cluster (n=6) having better survival (40.4 vs 22.6 months, p=0.039). Tumor sphericity in the arterial phase was the most relevant characteristic associated with a better prognosis (accuracy=0.93). Conclusion: FLHCC has unique features compared to conventional HCC, including young onset, gender balance, and absence of hepatopathy. Systemic therapies can provide encouraging survival, but lack of uniformity precludes defining a preferable regimen. Radiomics and NLR were suggested to correlate with prognosis and warrant further validation.

RESUMO

Prognostic markers in advanced hepatocellular carcinoma (HCC) are relevant for clinical decisions. Variations in inflammatory indexes, such as neutrophil-to-lymphocyte ratio (NLR) or platelet-to-lymphocyte ratio (PLR), may correlate with outcomes. In the present study, it was aimed to assess the prognostic role of inflammation indexes in patients with HCC and the evolutionary behavior of these variables within the first month of treatment in a cohort of patients treated with sorafenib from 2009-2021. Subgroups were divided based on the median of each variable ('low' or 'high)'. Survival was estimated using the Kaplan-Meier method. Hazard Ratio (HR) with 95% confidence interval (CI) were estimated using Cox regression models. A total of 373 patients were included, most Child-Pugh-A (83.1%) and BCLC-C (74%). Child-Pugh-A (P=0.011), performance status 0 (P<0.001), no ascites (P<0.001) and NLR<2.6 (P<0.001) were independently associated with improved survival. Baseline PLR was not correlated with survival (P=0.137). Patients who maintained low NLR at baseline and at 1 month (reference subgroup) had improved survival (18.6 months, 95% CI:15.4-22.0) compared with the subgroup that maintained high NLR at baseline and at 1 month (4.2 months, 95% CI:3.6-5.9), with HR: 3.80 (95% CI: 2.89-4.96). The subgroup with low NLR at baseline and high NLR at 1 month had a worse prognosis compared with the reference group (HR:1.4, 95% CI: 1.1-2.0), whereas the subgroup with high NLR at baseline and low at 1 month had similar outcome (HR:1.2, 95% CI: 0.8-1.6). It was concluded that evolutionary variation of NLR has a prognostic role in HCC patients under systemic therapy. This finding suggested that systemic inflammation and early modulation of the immune environment during treatment may correlate with outcomes.

RESUMO

Introduction and objectives: The incidence of cholangiocarcinoma (CCA) has been increasing globally. Although a concomitant increase in the incidence of metabolic disorders might suggest a causal relationship, the data are scarce. We aimed to describe the prevalence of metabolic disorders in patients with CCA and report the clinical features and outcomes. Patients and Methods: Retrospective study including patients with CCA. Patients were divided into: (1) past history of diabetes or/and overweight/obesity ("metabolic disorder group") and (2) without any of these features ("non-metabolic-disorder group"). A Cox regression model was used to determine the prognostic factors. Results: 122 patients were included. In total, 36 (29.5%) had overweight/obesity, 24 (19.7%) had diabetes, and 8 (6.6%) had both. A total of 29 (23.8%) patients had resectable disease and received upfront surgery. A total of 104 (85.2%) received chemotherapy for advanced/recurrent disease. The overall survival of the cohort was 14.3 months (95% CI: 10.1−17.3). ECOG-PS 0 (p < 0.0001), resectable disease (p = 0.018) and absence of vascular invasion (p = 0.048) were independently associated with better prognosis. The "metabolic disorder group" (n = 52) had a median survival of 15.5 months (95% CI 10.9−33.9) vs. 11.5 months (95% CI 8.4−16.5) in the "non-metabolic-disorder group" (n = 70) (HR: 1.10; 95% CI 0.62−1.94). Patients with resectable disease in the "metabolic group" had longer survival than patients in the "non-metabolic group" (43.4 months (95% CI 33.9-NR) vs. 21.8 months (95% CI 8.6−26.9); HR = 0.12, 95% CI 0.03−0.59). Conclusion: Metabolic disorders are frequent among CCA patients. Underlying metabolic comorbidities may be associated with prognosis in resectable CCA. There is a need to explore the mechanism that drives CCA carcinogenesis in a metabolic background.

RESUMO

Aim of the study: Hepatocellular carcinoma (HCC) is a lethal malignancy with heterogeneous behavior determined by liver function, clinical presentation and treatment response. Peritoneal metastasis (PM) from HCC is rare and management is challenging. We aim to report a cohort of patients with advanced HCC and describe demographic characteristics, treatment and outcomes of patients with PM. Material and methods: We analyzed data from a retrospective cohort of patients with HCC. Patients with PM were analyzed individually. Baseline characteristics, treatment strategy and median overall survival (OS) with 95% confidence interval (CI) were reported. Results: 238 patients with advanced HCC were evaluated. Eleven patients had PM: 7 patients were treated with systemic treatment and 4 were treated with upfront peritonectomy followed by systemic treatment at recurrence. These 4 patients had well-preserved liver function and low disease burden and were younger compared to the total cohort. The median time to recurrence after peritonectomy was 30.25 months (interquartile range [IQR]: 13.53-46.92): 3 of them presented peritoneal recurrence (2 with diffuse peritoneal spread and 1 with concomitant hepatic recurrence) and 1 presented pulmonary recurrence. Overall, patients with PM showed similar OS compared to patients with other metastatic sites (11.8 months; 95% CI: 1.5-19.8 vs. 8 months; 95% CI: 6.7-10, p = 0.901). Patients with PM treated with upfront surgery had a median OS of 60 months (95% CI: 16.7-not reached). Conclusions: Resection of PM from HCC may provide long-term survival in selected patients. A multidisciplinary approach is the optimal strategy for managing PM from HCC.

RESUMO

BACKGROUND: Despite atezolizumab and bevacizumab (A + B) is currently the first-line treatment for hepatocellular carcinoma (HCC) patients, some patients will not be adequate for this combination. In the setting of sorafenib some adverse events have been proposed as prognostic factors. OBJECTIVE: To characterize the early diarrhoea development as prognostic factor in 344 HCC patients. METHODS: The development of early diarrhoea in sorafenib treatment defined as patients who developed diarrhoea and needed dose modification within the first 60 days of treatment (e-diarrhoea) and 3-grouping variables were analysed: Patients with e-diarrhoea, patients who developed diarrhoea after the first 60 days of treatment (L-diarrhoea) and patients that never developed diarrhoea (never diarrhoea). RESULTS: The median overall survival in sorafenib treated patients was significantly different across groups (6.8 months for e-diarrhoea, 26.7 months for L-diarrhoea and 13.3 months for never-diarrhoea). The emergence of e-diarrhoea was associated with poor outcomes (hazard ratio [HR] 1.84 [95%CI 1.15-2.95]), while there was no increased/decreased risk of dismal evolution in patients with L-diarrhoea (HR 0.66 [95%CI 0.42-1.03]). CONCLUSION: The emergence of e-diarrhoea in HCC patients treated with sorafenib is an early predictor of dismal evolution under this therapy. Thus, prompt identification of these non-responders may be useful for an early switch to second-line therapies.

RESUMO

BACKGROUND/AIM: Dermatological adverse events (DAE) in hepatocellular carcinoma (HCC) patients treated with sorafenib predicts better outcome. Some turn into skin lesions (SL) requiring pathology examination. We describe incidence, characteristics and molecular profile of SL in HCC patients treated with sorafenib. MATERIALS AND METHODS: SL were prospectively collected in 311 HCC patients who started sorafenib. SL from sorafenib cohort were compared to those from a control patient group selected to match SL type and demographics. HRAS, KRAS and BRAF mutations were analyzed by CAST-PCR, mutated p53 and MAPK pathway activation by immunohistochemistry and immune infiltration by hematoxylin-eosin staining. RESULTS: Eighty-eight out of 311 patients developed DAE and 7.4% SL required histological assessment. Most frequent lesions were keratoacanthomas (n = 4), squamous-cell carcinomas (SCC)(n = 5), basal-cell carcinomas (BCC)(n = 3) and seborrheic keratosis (n = 5). HRAS and KRAS mutations were detected in 4 SL, while no mutations showed in control SL. Nuclear pERK immunostaining was identified in 33.3% of cases versus 5.3% of controls. Most SL (90%) from patients with DAE were proliferative with intense immune infiltration (73%). CONCLUSIONS: The onset of SL and their molecular profile did not impact negatively on patient's prognosis, but intense proliferation of SL may reflect compensatory activation of MAPK pathway and warrants their close monitoring.

RESUMO

Advanced hepatocellular carcinoma patients treated with sorafenib who develop early dermatologic adverse events (eDAEs) have a better prognosis. This may be linked to immune mechanisms, and thus, it is relevant to assess the association between peripheral immunity and the probability of developing eDAEs. Peripheral blood mononuclear cells of 52 HCC patients treated with sorafenib were analyzed at baseline and throughout the first eight weeks of therapy. T, B, Natural Killer cells, and their immune checkpoints expression data were characterized by flow cytometry. Cytokine release and immune-suppression assays were carried out ex vivo. Cox baseline and time-dependent regression models were applied to evaluate the probability of increased risk of eDAEs. DNAM-1, PD-1, CD69, and LAG-3 in T cells, plus CD16 and LAG-3 in NK cells, are significantly associated with the probability of developing eDAEs. While NK DNAM-1+ cells express activation markers, T DNAM-1+ cells induce immune suppression and show immune exhaustion. This is the first study to report an association between immune checkpoints expression in circulating immune cells and the increased incidence of eDAEs. Our results support the hypothesis for an off-target role of sorafenib in immune modulation. We also describe a novel association between DNAM-1 and immune exhaustion in T cells.

RESUMO

OBJECTIVES: To evaluate the efficacy and safety of sorafenib in elderly patients with advanced hepatocellular carcinoma (HCC). METHODS: We analyzed data from a cohort of patients with advanced HCC treated using systemic treatment according to the local institutional protocol. Patients were divided into two groups, Group A, individuals <70 years of age, and Group B, individuals 70 years of age or older at the time of treatment initiation. Efficacy, measured based on overall survival (OS) and time to treatment failure (TTF), and toxicity were compared between groups. RESULTS: A total of 238 patients with advanced HCC who received sorafenib between 2007 and 2018 were evaluated. The median age for Group A was 59.1 years and that for Group B 73.6 years. The major prognostic characteristics were balanced between the groups. There were no significant differences in OS between Group A (8.0 months, 95%CI 6.34-9.3) and Group B (9.0 months, 95%CI 5.38-12.62), p=0.433, or in TTF between Group A (3.0 months, 95%CI 2.39-3.60) and Group B (3.0 months, 95%CI 1.68-4.32), p=0.936. There were no significant differences between Groups A and B with respect to the incidence of adverse events or treatment discontinuation because of toxicity. CONCLUSION: Efficacy and safety of sorafenib did not differ significantly between younger and older patients with HCC. Our data suggest that age alone should not restrict clinical decision-making for patients with advanced HCC.

RESUMO

BACKGROUND AND AIMS: Immune-checkpoint inhibitors are effective in many advanced tumors. However, there is scarce information regarding the radiological response to these agents in hepatocellular carcinoma outside clinical trials. We aimed to describe the radiological response in a retrospective cohort of hepatocellular carcinoma patients treated with nivolumab and to analyze the radiological evolution according to tumor response at first post-treatment radiological assessment. METHODS: We reviewed pre-treatment and post-treatment images (CT or MRI) obtained at different time-points in patients with hepatocellular carcinoma treated with nivolumab outside clinical trials at seven Spanish centers, assessing the response according to RECIST 1.1 and iRECIST and registering atypical responses. We also analyzed the imaging findings on subsequent assessments according to tumor status on the first posttreatment imaging assessment. RESULTS: From the 118 patients with hepatocellular carcinoma treated with nivolumab, we finally analyzed data from 31 patients (71 % Child-Pugh A; 74 % BCLC-C). Median follow-up was 8.39 months [IQR 5.00-10.92]; median overall survival was 12.82 months (95 %CI 10.92-34.79). According to RECIST 1.1, the objective response rate was 16 % and according to iRECIST, the objective response rate was 22.6 %. Findings at the first post-treatment assessment varied, showing stable disease in 44.8 % of patients; findings during follow-up also varied widely, including 4 hyperprogressions and 3 pseudoprogressions. CONCLUSION: Imaging findings during nivolumab treatment are heterogeneous between and within patients. Progression of disease does not always signify treatment failure, and surrogate end-points may not reflect survival outcomes, making the management of hepatocellular carcinoma patients under immunotherapy challenging.

RESUMO

A virtual expert roundtable was convened on April 16, 2020, to discuss the evolving landscape of care for treating patients with advanced hepatocellular carcinoma (HCC) and discuss questions related to patient care and treatment selection. This commentary presents highlights from this discussion and provides an expert opinion about approaches to treatment for HCC in the Americas and the European Union. We anticipate that atezolizumab plus bevacizumab will become the standard of care for advanced HCC patients. However, this approach will make decisions regarding the sequencing of treatments for second-line therapies and beyond more challenging. Therapy will require individualization based on patient characteristics and preferences, while insurance coverage decisions and requirements may also impact the options that patients can access. Additional research regarding prognostic and predictive biomarkers is needed to help better identify optimal treatment approaches for specific patient populations. Multidisciplinary tumor boards will continue to play a critical role in guiding treatment selection for individual patients. Atezolizumab plus bevacizumab offers a promising new first-line therapeutic option for patients with advanced HCC, but more research is needed to optimize and individualize patient therapy.

RESUMO

Sorafenib was the first tyrosine kinase inhibitor (TKI) that showed success in extending survival in patients with advanced hepatocellular carcinoma (HCC). In recent years, additional TKIs have been shown to improve survival and expanded the armamentarium for treating this malignancy. The current landscape includes other classes of drugs, such as immune checkpoint inhibitors and monoclonal antibodies. The challenge is now placed on how to best select, combine, and sequence drugs with the goal of improving efficacy and minimizing toxicities to deliver better outcomes for HCC patients.

RESUMO

BACKGROUND & AIMS: Sorafenib and lenvatinib are the first-line treatments approved in hepatocellular carcinoma (HCC), but information is lacking about the relationships between their pharmacokinetics, patients pharmacogenetic profiles, adverse events (AE) and overall survival. We aimed to elucidate these relationships of tyrosine Kinase Inhibitors, such as sorafenib, in order to improve the design of trials testing it in combination with checkpoint inhibitors. METHODS: We assessed the pharmacokinetics of sorafenib and its N-oxide metabolite at day-0, day-7, day-30, day-60, day-90, day-120, day-150 and day-180 and nine single-nucleotide polymorphisms (SNP) in five genes related to sorafenib metabolism/transport to identify the best point for starting the combination between tyrosine kinases and checkpoint inhibitors. RESULTS: We prospectively included 49 patients (96% cirrhotic, 37% hepatitis-C, 82% Child-Pugh-A and 59% BCLC-C). Pharmacokinetic values peaked at day-7 and progressively declined until day-60. In the 16 patients without further dose modifications after day-60, pharmacokinetic values remained stable through day-180 (sorafenib P = .90; N-oxide P = .93). Pharmacokinetic values were higher in patients with early dermatological adverse events and lower in patients with early diarrhoea. Sorafenib and N-oxide pharmacokinetic values varied linearly with different alleles of MRP2*3972. CONCLUSIONS: Sorafenib's pharmacokinetics is heterogeneous across HCC patients. This heterogeneity affects adverse events development and must be taken into account in setting the dose and timing of its combination with checkpoint inhibitors.

RESUMO

BACKGROUND & AIMS: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. METHODS: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. RESULTS: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dialysis (0.36%). The median age was 65.5 years, 40.9% had hepatitis C, 75% had Child-Pugh A, and 85% were Barcelona Clinic Liver Cancer-C. The median time to first dose modification, treatment duration and overall survival rate were 2.4 months (interquartile ranges [IQR], 0.8-3.8), 10.8 months (IQR, 4.5-16.9), and 17.5 months (95% CI, 7.2-24.5), respectively. Seventeen patients required at least 1 dose modification. The main causes of first dose modification were asthenia/worsening of Eastern Cooperative Oncology Group-Performance Status and diarrhoea. At the time of death or last follow-up, four patients were still on treatment and 18 had discontinued sorafenib: 14 were due to tumour progression, 2 were sorafenib-related, and 2 were non-sorafenib-related AE. CONCLUSIONS: The outcomes observed in this cohort seem comparable to those in the non-dialysis population. Thus, to the best of our knowledge, this is the largest and most informative dataset regarding systemic treatment outcomes in HCC patients undergoing dialysis.

RESUMO

PURPOSE: To assess the effectiveness, safety, and overall survival (OS) of thermal ablation as upfront treatment of intrahepatic colangiocarcinoma (ICC) in patients with cirrhosis. MATERIALS AND METHODS: This was a retrospective analysis of all biopsy-confirmed ICC in cirrhotic patients treated in the authors' unit from 2001 to 2017. Baseline characteristics, ablation procedures, and complications were recorded, and time to recurrence (TTR) and OS were calculated. Twenty-seven patients were identified. Seventy percent had Child-Pugh A disease, and most had clinically significant portal hypertension. Median tumor size was 21 mm. Twenty-one cases were uninodular, and 10 were single ≤ 2 cm. RESULTS: Complete radiologic necrosis was achieved in 25 cases (92.6%). Median OS was 30.6 months (95% confidence interval [CI], 22.6-46.5), and recurrence was detected in 21 cases (77.8%) with a TTR of 10.1 months (95% CI, 7.7-20.9). In those patients with single ≤ 2-cm ICC, the OS was 94.5 months (95% CI, 11.7-not reached). Differences in OS were statistically significant between patients with single ICC ≤ 2 cm and patients with single ICC > 2 cm (P = .04) and between patients with single ICC > 2 cm and patients with multinodular ICC (P = .02). Only 1 patient had a treatment-related complication. CONCLUSIONS: Thermal ablation is a safe and effective treatment for ICC in patients with cirrhosis who are not candidates for surgery. The OS is similar to that reported in surgical series, but the initial treatment success is hampered by a high rate of tumor recurrence. Encouraging long-term survival after thermal ablation is achieved in patients with single ≤ 2-cm ICC.
