Demographic, Clinical and Treatment Characteristics of Patients with Hepatocellular Cancer: 10 Years of Experience of a Single Center

Primary cancers of the liver are in the 3rd place in cancer-related deaths. Hepatocellular carcinoma (HCC) accounts for approximately 80% of primary hepatic malignancies. The Barcelona Clinic Liver Cancer (BCLC) classification divides HCC into 5 stages and allocates treatments. The aim of this study is to examine the initial treatments of HCC patients in our center and compare them with the approaches in the guidelines. The data of patients diagnosed with HCC between 2006 and 2016 were recruited retrospectively. Age, gender, etiology, Child-Pugh score, BCLC stage, model for end-stage liver disease score, alpha-fetoprotein level, tumor characteristics, type of first treatment and survival time were evaluated. There were 228 men and 33 women. The mean age was 61±10.5. Of the 130 patients 77 were found on BCLC stage C. The first treatment according to BCLC stage were sorafenib in 22, resection in 16, TACE in 15, Ytrium-90 in 14, systemic chemotherapy other than sorafenib in 14, transplantation in 11, palliative treatment in 8, and ablation in 4 patients. The median survival time was 11.9 (8.1-15.9) months. One-year survival was 32%, three-year survival was 19%, and five-year survival was 16%. The management of HCC patients was performed according to more than just BCLC guidelines in our center. The high number of patients who did not receive treatment may indicate that we need to show sufficient clinical attention to Stage D patients.

Hepatobiliary-phase gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid MRI for pretreatment prediction of efficacy-to-standard-therapies based on Barcelona Clinic Liver Cancer algorithm: an up-to-date review.

Recent advances in systemic therapy have had major impacts on treatment strategies for hepatocellular carcinoma (HCC). The 2022 Barcelona Clinic Liver Cancer (BCLC) guidelines incorporate a new section on clinical decision-making for personalized medicine, although the first treatment suggested by the BCLC guidelines is based on solid scientific evidence. More than ever before, the appropriate treatment strategy must be selected prior to the initiation of therapy for HCC. Gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid magnetic resonance imaging (Gd-EOB-DTPA-MRI) is essential for liver imaging and the hepatobiliary phase (HBP) of EOB-MRI reflects the expression of organic anion transporting polypeptide (OATP) transporters. Molecules associated with OATP expression are relevant in the molecular classification of HCC subclasses, and EOB-MRI is becoming increasingly important with advances in the molecular and genetic understanding of HCC. In this review, we describe imaging findings for the pretreatment prediction of response to standard therapies for HCC based on the BCLC algorithm using the HBP of EOB-MRI, with specific attention to the molecular background of OATPs. A more complete understanding of these findings will help radiologists suggest appropriate treatments and clinical follow-ups and could lead to the development of more personalized treatment strategies in the future. CLINICAL RELEVANCE STATEMENT: In the coming era of personalized medicine, HBP of EOB-MRI reflecting molecular and pathological factors could play a predictive role in the therapeutic efficacy of HCC and contribute to treatment selection. KEY POINTS: • Imaging features of hepatobiliary phase predict treatment efficacy prior to therapy and contribute to treatment choice. • Wnt/β-catenin activation associated with organic anion transporting polypeptide expression is involved in the tumor immune microenvironment and chemo-responsiveness. • Peritumoral hypointensity of hepatobiliary phase reflecting microvascular invasion affects the therapeutic efficacy of locoregional to systemic therapy.

Adherence to Tumor Board Recommendations in the Treatment of Patients with Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a heterogeneous disease that typically arises in the setting of chronic liver disease, making treatment selection complex. Multidisciplinary liver tumor boards (MDLTB) have been shown to improve outcomes in patients with HCC. However, in many cases, patients evaluated by MDLTBs ultimately do not receive the board's recommended treatment. This study aims to assess adherence to MDLTB recommendations for the treatment of HCC, the reasons for non-adherence, and the survival of Barcelona Clinic Liver Cancer (BCLC) Stage A patients treated with curative treatment compared to palliative locoregional therapy. A single-site, retrospective cohort study was conducted of all patients with treatment-naïve HCC who were evaluated by an MDLTB at a tertiary care center in Connecticut between 2013 and 2016, of which 225 patients met inclusion criteria. Investigators conducted a chart review and recorded adherence to the MDLTB's recommendations, and in cases of discordance, evaluated and recorded the underlying cause; investigators assessed MDLTB recommendations' compliance with BCLC guidelines. Survival data was accrued through February 1st of 2022 and analyzed via Kaplan-Meier analysis and multivariate Cox regression. Treatment adherent to MDLTB recommendations occurred in 85.3% of patients (n=192). The majority of non-adherence occurred in the management of BCLC Stage A disease. In cases where adherence was possible but the recommendation was not followed, most discrepancies were whether to treat with curative or palliative intent (20/24), with almost all discrepancies occurring in patients (19/20) with BCLC Stage A disease. For patients with Stage A unifocal HCC, those who received curative therapy lived significantly longer than patients who received palliative locoregional therapy (5.55 years vs 4.26 years, p=0.037). Most forms of non-adherence to MDLTB recommendations were unavoidable; however, treatment discordance in the management of patients with BCLC Stage A unifocal disease may present an opportunity for clinically significant quality improvement.

Radiological findings in non-surgical recurrent hepatocellular carcinoma: From locoregional treatments to immunotherapy

Since hepatocellular carcinoma (HCC) represents an important cause of mortality and morbidity all over the world. Currently, it is fundamental not only to achieve a curative treatment but also to manage in the best way any possible recurrence. Even if the latest update of the Barcelona Clinic Liver Cancer guidelines for HCC treatment has introduced new locoregional techniques and confirmed others as well-established clinical practices, there is still no consensus about the treatment of recurrent HCC (RHCC). Locoregional treatments and medical therapy represent two of the most widely accepted approaches for disease control, especially in the advanced stage of liver disease. Different medical treatments are now approved, and others are under investigation. On this basis, radiology plays a central role in the diagnosis of RHCC and the assessment of response to locoregional treatments and medical therapy for RHCC. This review summarized the actual clinical practice by underlining the importance of the radiological approach both in the diagnosis and treatment of RHCC.

A preoperative model for predicting early recurrence in patients undergoing resection for single hepatocellular carcinoma

Background and aimThe updated Barcelona Clinic Liver Cancer guidelines recommend liver resection (LR) for patients with single hepatocellular carcinoma (HCC) of any size. This study developed a preoperative model for predicting early recurrence in patients undergoing LR for single HCC. Materials and methodsWe identified 773 patients undergoing LR for single HCC between 2011 and 2017 from the cancer registry database of our institution. Multivariate Cox regression analyses were performed to construct a preoperative model for predicting early recurrence, i.e., recurrence within 2 years of LR. ResultsEarly recurrence was identified in 219 patients (28.3%). The final model of early recurrence included four predictive factors—alpha-fetoprotein level of ≥20 ng/mL, tumor size of >30 mm, Model for End-Stage Liver Disease score of >8, and cirrhosis. Preoperative application of this model provided three risk strata for recurrence-free survival (RFS): low risk, with 2-year RFS of 79.8% (95% confidence interval [CI]: 75.7–84.2%); intermediate risk, with 2-year RFS of 66.6% (95% CI: 61.1–72.6%); and high risk, with 2-year RFS of 51.1% (95% CI: 43.0–60.8%). ConclusionWe developed a preoperative model for predicting early recurrence after LR for single HCC. This model provides useful information for clinical decision-making.

Liver resection for hepatocellular carcinoma beyond the BCLC: are multinodular disease, portal hypertension, and portal system invasion real contraindications?

Barcelona Clinic Liver Cancer (BCLC) is a recognized guideline to standardize treatment allocation for hepatocellular carcinoma (HCC); however, many centers criticize its restrictive liver resection recommendations and have published good results after more liberal hepatectomy indications. The objective is to evaluate the results of HCC resection in a single center, with a more liberal indication for resection than proposed by the BCLC guideline. It was performed a retrospective cohort study including all patients who underwent liver resection for HCC in a single center between April 2008 and November 2018. The results of 150 patients who underwent hepatectomy were evaluated and compared facing both 2010 and 2018 BCLC guidelines. Overall and disease-free survival after resection in patients with none, one, two, or three of the risk factors, as proposed by the BCLC, as contraindications to resection (portal hypertension, portal invasion, and more than one nodule) were analyzed. Nodule size and presence of portal invasion alone did not affect prognosis. If the BCLC 2010 and 2018 guidelines were followed, 46.7% and 26.7% of the patients, respectively, would not have received potentially curative treatment. The median overall and disease-free survival for patients with one BCLC contraindication factor were 43.3 and 15.1 months, respectively. The presence of two risk factors had a negative impact on overall survival (OS) and disease-free survival (DFS), although some patients had long-term survival. The only patient with the three risk factors had a poor outcome. Selected patients with one BCLC contraindication factor may undergo resection with good results, whereas those with two factors should be allocated for hepatectomy only in favorable scenarios. Patients with the three risk factors do not appear to benefit from resection.

Treatment patterns for hepatocellular carcinoma in patients with Child-Pugh class B and their impact on survival: A Korean nationwide registry study.

There are no established practice guidelines for treating hepatocellular carcinoma (HCC) in patients with Child-Turcotte-Pugh (CTP) class B liver function. To evaluate the impact of various initial treatment modalities on these patients, we conducted a nationwide registry study in Korea. Treatment patterns and overall survival (OS) of patients with HCC and CTP class B according to initial treatment modalities in each Barcelona Clinic Liver Cancer (BCLC) stage were analysed using data from the Korean Primary Liver Cancer Registry between 2008 and 2016. Initial treatment modalities were categorized as standard, alternative treatment and supportive care only, referring to the 2018 BCLC guidelines, irrespective of liver function. Of the 2318 newly diagnosed Korean patients with HCC and CTP class B, 29.7%, 60.3% and 15.6% of patients in BCLC stages A, B and C, respectively, underwent standard treatment. Adjusted OS hazard ratios of alternative treatment referring to standard treatment were 1.55 (95% confidence interval [CI], 1.25-1.94; p< .001) in BCLC-A, 0.82 (95% CI, 0.43-1.56; p= .550) for curative alternative treatment, 1.89 (95% CI, 0.97-3.68; p= .059) for non-curative alternative treatment in BCLC-B, 0.40 (95% CI, 0.28-0.56; p< .001) for curative alternative treatment, 0.84 (95% CI, 0.69-1.02; p= .076) for non-curative alternative treatment for BCLC-C. Regardless of BCLC stages, chemoembolization was conducted the most among patients with CTP class B. Treatment in line with the BCLC treatment algorithm resulted in favourable OS outcomes, except for those with BCLC stage C, as systemic therapy showed poor OS.

Role of interventional oncology in hepatocellular carcinoma: Future best practice beyond current guidelines.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths globally. Liver transplant remains the goal of curative treatment, but limited supply of organs decreases accessibility and prolongs waiting time to transplantation. Therefore, interventional oncology therapies have been used to treat the majority of HCC patients, including those awaiting transplant. The Barcelona Clinic Liver Cancer (BCLC) classification is the most widely used staging system in management of HCC that helps allocate treatments. Since its inception in 1999, it was updated for the fifth time in November 2021 and for the first time shaped by expert opinions outside the core BCLC group. The most recent version includes additional options for early-stage disease, substratifies intermediate disease into three groups, and lists alternates to Sorafenib that can double the expected survival of advanced-stage disease. The group also proposed a new BCLC staging schema for disease progression, and endorsed treatment stage migration (TSM) directly into the main staging and treatment algorithm. This article reviews the recent developments underlying the current BCLC guidelines and highlights ongoing research, particularly involving radioembolization, that will shape future best practice.

Hepatocellular carcinoma in patients with renal dysfunction: Pathophysiology, prognosis, and treatment challenges.

The population of patients with hepatocellular carcinoma (HCC) overlaps to a high degree with those for chronic kidney disease (CKD) and end-stage renal disease (ESRD). The degrees of renal dysfunction vary, from the various stages of CKD to dialysis-dependent ESRD, which often affects the prognosis and treatment choice of patients with HCC. In addition, renal dysfunction makes treatment more difficult and may negatively affect treatment outcomes. This study summarized the possible causes of the high comorbidity of HCC and renal dysfunction. The possible mechanisms of CKD causing HCC involve uremia itself, long-term dialysis status, immunosuppressive agents for postrenal transplant status, and miscellaneous factors such as hormone alterations and dysbiosis. The possible mechanisms of HCC affecting renal function include direct tumor invasion and hepatorenal syndrome. Finally, we categorized the risk factors that could lead to both HCC and CKD into four categories: Environmental toxins, viral hepatitis, metabolic syndrome, and vasoactive factors. Both CKD and ESRD have been reported to negatively affect HCC prognosis, but more research is warranted to confirm this. Furthermore, ESRD status itself ought not to prevent patients receiving aggressive treatments. This study then adopted the well-known Barcelona Clinic Liver Cancer guidelines as a framework to discuss the indicators for each stage of HCC treatment, treatment-related adverse renal effects, and concerns that are specific to patients with pre-existing renal dysfunction when undergoing aggressive treatments against CKD and ESRD. Such aggressive treatments include liver resection, simultaneous liver kidney transplantation, radiofrequency ablation, and transarterial chemoembolization. Finally, focusing on patients unable to receive active treatment, this study compiled information on the latest systemic pharmacological therapies, including targeted and immunotherapeutic drugs. Based on available clinical studies and Food and Drug Administration labels, this study details the drug indications, side effects, and dose adjustments for patients with renal dysfunction. It also provides a comprehensive review of information on HCC patients with renal dysfunction from disease onset to treatment.

Rethinking the Barcelona clinic liver cancer guidelines: Intermediate stage and Child-Pugh B patients are suitable for surgery?

According to Barcelona Clinic Liver Cancer recommendations, intermediate stage hepatocellular carcinomas (stage B) are excluded from liver resection and are referred to palliative treatment. Moreover, Child-Pugh B patients are not usually candidates for liver resection. However, many hepatobiliary centers in the world manage patients with intermediate stage hepatocellular carcinoma or Child-Pugh B cirrhosis with liver resection, maintaining that hepatic resection is not contraindicated in selected patients with non–early-stage hepatocellular carcinoma and without normal liver function. Several studies demonstrate that resection provides the best survival benefit for selected patients in very early/early and even in intermediate stages of Barcelona Clinic Liver Cancer classification, and this treatment gives good results in the setting of multinodular, large tumors in patients with portal hypertension and/or Child-Pugh B cirrhosis. In this review we explore this controversial topic, and we show through the literature analysis how liver resection may improve the short- and long-term survival rate of carefully selected Barcelona Clinic Liver Cancer B and Child-Pugh B hepatocellular carcinoma patients. However, other large clinical studies are needed to clarify which patients with intermediate stage hepatocellular carcinoma are most likely to benefit from liver resection.

Hepatocellular Carcinoma in Korea: an Analysis of the 2015 Korean Nationwide Cancer Registry.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the second leading cause of cancer-related death in Korea. This study evaluated the characteristics of Korean patients newly diagnosed with HCC in 2015. Data from the Korean Primary Liver Cancer Registry (KPLCR), a representative sample of patients newly diagnosed with HCC in Korea, were analyzed. A total of 1,558 patients with HCC registered in the KPLCR in 2015 were investigated. The median age was 61.0 years (interquartile range, 54.0-70.0 years), and men accounted for 79.7% of the subjects. Hepatitis B virus infection was the most common underlying liver disease (58.1%). According to the Barcelona Clinic Liver Cancer (BCLC) staging system, stage 0, A, B, C, and D HCCs accounted for 14.2%, 31.5%, 7.6%, 39.0%, and 7.8% of patients, respectively. Transarterial therapy (32.1%) was the most commonly performed initial treatment, followed by surgical resection (23.2%), best supportive care (20.2%), and local ablation therapy (10.7%). Overall, 34.5% of patients were treated in accordance with the BCLC guidelines: 59.2% in stage 0/A, 48.4% in stage B, 18.1% in stage C, and 71.6% in stage D. The 1-, 3-, and 5-year OS rates were 67.1%, 50.9%, and 27.0%, respectively. In 2015, approximately 45% of Korean HCC cases were diagnosed at a very early or early stage, and 35% of patients underwent potentially curative initial treatment. BCLC guidance was followed in 34.5% of patients; in patients with stage B or C disease, there was relatively low adherence.

Adherence to the modified Barcelona Clinic Liver Cancer guidelines: Results from a high-volume liver surgery center in East Asias.

The Barcelona Clinic Liver Cancer (BCLC) staging system is the most widely applied staging system for hepatocellular carcinoma (HCC) and is recommended for treatment allocation and prognostic prediction. The BCLC guidelines were modified in 2018 to indicate that Child-Pugh A without any ascites is essential for all stages except stage D. This study sought to provide a description of patients with HCC treated at a high-volume liver surgery center in Taiwan where referral is not needed and all treatment modalities are available and reimbursed by the National Health Insurance program. As such, certain variables that could modulate treatment decisions in clinical practice, including financial constraints, the availability of treatment procedures, and the expertise of the hospital, could be excluded. The study further sought to evaluate the adherence to the modified BCLC guidelines. This was a retrospective study with prospectively collected data. 1801 consecutive patients with de novo HCC were enrolled through our institution from 2011-2017. There were 302 patients with stage 0, 783 with stage A, 242 with stage B, 358 with stage C, and 116 with stage D HCC. Treatment adhering to the modified BCLC guidelines recommendations was provided to 259 (85.8%) stage 0 patients, 606 (77.4%) stage A patients, 120 (49.6%) stage B patients, 93 (26.0%) stage C patients, and 83 (71.6%) stage D patients. We reported treatment adhering to the modified BCLC guidelines at a high-volume liver surgery center in Taiwan. We found that non-adherence to the modified BCLC staging system was common in treating stage B and C patients.

Effect of Performance Status on Short-term and Long-Term Outcomes After Liver Resection for Hepatocellular Carcinoma: A Multicenter Study

Background: The Barcelona Clinic Liver Cancer (BCLC) categorizes a patient with performance status (PS)-1 as advanced stage of hepatocellular carcinoma (HCC) and surgical resection is not recommended. However, in real-world clinical practice, PS-1 is often not a contraindication to surgery for HCC. The aim of current study was to define the impact of PS on the surgical outcomes of patients undergoing liver resection for HCC. Methods: Using a multi-institutional database, 1,531 consecutive patients who underwent a curative-intent resection of HCC between 2005 and 2015 were identified. After categorizing patients into PS-0 (n=836) versus PS-1 (n=695), perioperative mortality and morbidity, overall survival (OS) and recurrence-free survival (RFS) were compared. Results: Overall perioperative mortality and major morbidity among patients with PS-0 (n=836) and PS-1 (n=695) were similar (1.4% vs. 1.6%, P=0.525 and 9.7% vs. 10.2%, P=0.732, respectively). In contrast, median OS and RFS was worse among patients who had PS-1 versus PS-0 (34.0 vs. 107.6 months, and 20.5 vs. 60.6 months, both P< 0.001, respectively). On multivariable Cox-regression analyses, PS-1 was independently associated with worse OS (HR: 1.301, 95% CI: 1.111-1.523, P < 0.001) and RFS (HR: 1.184, 95% CI: 1.034-1.358, P = 0.007). Conclusions: Patients with PS-1 versus PS-0 had comparable perioperative outcomes. However, patients with PS-1 had worse long-term outcomes as PS-1 was independently associated with worse OS and RFS. Routine exclusion of HCC patients with PS-1 from surgical resection as recommended by the BCLC guidelines is not warranted.

Real-World Data on Clinical Outcomes of Patients with Liver Cancer: A Prospective Validation of the National Cancer Centre Singapore Consensus Guidelines for the Management of Hepatocellular Carcinoma

Introduction: Real-world management of patients with hepatocellular carcinoma (HCC) is crucially challenging in the current rapidly evolving clinical environment which includes the need for respecting patient preferences and autonomy. In this context, regional/national treatment guidelines nuanced to local demographics have increasing importance in guiding disease management. We report here real-world data on clinical outcomes in HCC from a validation of the Consensus Guidelines for HCC at the National Cancer Centre Singapore (NCCS). Method: We evaluated the NCCS guidelines using prospectively collected real-world data, comparing the efficacy of treatment received using overall survival (OS) and progression-free survival (PFS). Treatment outcomes were also independently evaluated against 2 external sets of guidelines, the Barcelona Clinic Liver Cancer (BCLC) and Hong Kong Liver Cancer (HKLC). Results: Overall treatment compliance to the NCCS guidelines was 79.2%. Superior median OS was observed in patients receiving treatment compliant with NCCS guidelines for early (nonestimable vs. 23.5 months p < 0.0001), locally advanced (28.1 vs. 22.2 months p = 0.0216) and locally advanced with macrovascular invasion (10.3 vs. 3.3 months p = 0.0013) but not for metastatic HCC (8.1 vs. 6.8 months p = 0.6300), but PFS was similar. Better clinical outcomes were seen in BCLC C patients who received treatment compliant with NCCS guidelines than in patients with treatment only allowed by BCLC guidelines (median OS 14.2 vs. 7.4 months p = 0.0002; median PFS 6.1 vs. 4.0 months p = 0.0286). Clinical outcomes were, however, similar for patients across all HKLC stages receiving NCCS-recommended treatment regardless of whether their treatment was allowed by HKLC. Conclusion: The high overall compliance rate and satisfactory clinical outcomes of patients managed according to the NCCS guidelines confirm its validity. This validation using real-world data considers patient and treating clinician preferences, thus providing a realistic analysis of the usefulness of the NCCS guidelines when applied in the clinics.

Liver resection of hepatocellular carcinoma within and beyond the Barcelona Clinic Liver Cancer guideline recommendations: Results from a high-volume liver surgery center in East Asia.

The Barcelona Clinic Liver Cancer (BCLC) guidelines were updated in 2012, and a single large hepatocellular carcinoma (HCC) more than 5 cm was regarded as BCLC stage A rather than B in the updated version. In this study, we sought to re-evaluate the outcomes of patients with HCC who underwent liver resection (LR) within (stage 0 and A) and beyond (stage B and C) the BCLC guideline recommendations of the updated BCLC staging system. This retrospective study enrolled 774 consecutive patients with naïve HCC who underwent LR from 2011 to 2018 at our institution. The overall survival (OS) and recurrence-free survival (RFS) of these patients were examined. Of the patients, 606 had BCLC stage 0 or A HCC, and 168 had BCLC stage B or C HCC. The 5-year OS and RFS among the patients within the BCLC criteria for LR were 75.2% and 56.1%, respectively, vs 54.9% and 34.0%, respectively, among the patients beyond the BCLC criteria (P < .001). Alpha-fetoprotein more than 400 ng/mL (hazard ratio = 2.06, 95% confidence interval, 1.31-3.26, P = .002) was the only independent variable associated with recurrence among the patients beyond the BCLC criteria. LR provided acceptable outcomes among selected patients with BCLC stage B and C HCC.

Recurrence Patterns and Outcomes after Resection of Hepatocellular Carcinoma within and beyond the Barcelona Clinic Liver Cancer Criteria.

Several investigators have advocated for extending the Barcelona Clinic Liver Cancer (BCLC) resection criteria to select patients with BCLC-B and even BCLC-C hepatocellular carcinoma (HCC). The objective of the current study wasto define the outcomes and recurrence patterns after resection within and beyond the current resection criteria. Patients who underwent resection for HCC within (i.e., BCLC 0/A) and beyond (i.e. BCLC B/C) the current resection criteria between 2005 and 2017 were identified from an international multi-institutional database. Overall survival (OS), disease-free survival (DFS), as well as patterns of recurrence of patients undergoing HCC resection within and beyond the BCLC guidelines were examined. Among 756 patients, 602 (79.6%) patients were BCLC 0/A and 154 (20.4%) were BCLC B/C. Recurrences were mostly intrahepatic (within BCLC: 74.3% versus beyond BCLC: 70.8%, p = 0.80), with BCLC B/C patients more often having multiple tumors at relapse (69.6% versus 49.4%, p = 0.001) and higher rates of early (< 2 years) recurrence (88.0% versus 75.5%, p = 0.011). During the first postoperative year, annual recurrence was 38.3% and 21.3% among BCLC B/C and BCLC 0/A patients, respectively; 5-year OS among BCLC 0/A and BCLC B/C patients was 76.9% versus 51.6% (p = 0.003). On multivariable analysis, only a-fetoprotein (AFP) > 400ng/mL(HR = 1.84, 95% CI 1.07-3.15) and R1 resection (HR = 2.36, 95% CI 1.32-4.23) were associated with higher risk of recurrence among BCLC B/C patients. Surgery can provide acceptable outcomes among select patients with BCLC B/C HCC. The data emphasize the need to further refine the BCLC treatment algorithm as well as highlight the need for surveillance protocols with a particular focus on the liver, especially for patients undergoing resection outside the BCLC criteria.

3:54 PM Abstract No. 28 Predictors of survival in patients with advanced (Barcelona Clinic Liver Cancer C) hepatocellular carcinoma undergoing Yttrium-90 radioembolization therapy

To identify key clinical and imaging predictors of survival in patients undergoing Yttrium-90 radioembolization (Y90-RE) for advanced, Barcelona Clinic Liver Cancer (BCLC) C, hepatocellular carcinoma (HCC). In an IRB-approved study, patients with BCLC C HCC who underwent Y90-RE were retrospectively identified. Reason for BCLC C Status (i.e., Eastern Cooperative Oncology Group performance status (ECOG-PS), macrovascular invasion, and/or extrahepatic metastasis) and additional pre and post Y90-RE prognostic factors were recorded and analyzed. Median overall survival (OS) from first Y90-RE was calculated using Kaplan-Meier estimation and potential prognostic factors were tested for significance (p ≤0.05) using log-rank analysis. Between 2013 and 2018, 97 BCLC C HCC patients (79% male; 65 years mean age) underwent Y90-RE with a median OS (95% CI) of 13.7 months (10.8-16.9). Median OS for the 40 (41%) ECOG-PS driven BCLC C patients versus the 57 (59%) macrovascular invasion and/or extrahepatic metastasis driven BCLC C patients was 14.5 (10.8-20.5) versus 13.2 (6.9-16.9) months, respectively (p = 0.9). Prognostic factors associated with a prolonged median OS were absence of hepatic vein invasion (14.9 vs. 5.3; p = 0.0002), single hepatic lobe burden (15.4 vs. 7.2; p = 0.04), absence of anorexia (14.6 vs. 6.1; p = 0.004), normal baseline alkaline phosphatase (19.1 vs. 9.0; P <0.0001), normal baseline serum sodium (14.9 vs. 5.2; p = 0.01), greater post Y90-RS tumor shrinkage (14.9 vs. 5.2; p = 0.01), attainment of Milan eligibility status (20.8 vs. 9.6; p = 0.001), and complete/partial tumor response per mRECIST (17.5 vs. 7.3; p = 0.01). Y90-RE is an effective therapy for the treatment of BCLC C hepatocellular carcinoma patients, resulting in an overall survival that is equivalent, if not favorable, to currently allocated therapies per BCLC guidelines. Certain pre Y90-RE clinical and imaging characteristics are associated with an improved overall survival.Tabled 1Prognostic Factors, in median OS (95% CI) monthsPresentAbsentPHepatic vein invasion5.314.90.0002Single hepatic lobe burden15.47.20.04Anorexia6.114.60.004Normal baseline alkaline phosphatase19.19.00.0001Normal baseline sodium blood levels18.07.10.014Greater tumor shrinkage14.95.20.01Attained Milan eligibility status20.89.60.001Attained complete or partial tumor response, per mRECIST17.57.30.01 Open table in a new tab

A nomogram to predict survival of patients with intermediate-stage hepatocellular carcinoma after transarterial chemoembolization combined with microwave ablation.

To develop a prognostic nomogram based on the albumin-bilirubin (ALBI) grade for prediction of the long-term survival of patients with intermediate-stage hepatocellular carcinoma (HCC) after transarterial chemoembolization combined with microwave ablation (TACE-MWA). We retrospectively studied 546 consecutive patients with intermediate-stage HCC according to the Barcelona Clinic Liver Cancer guidelines who underwent TACE-MWA between January 2000 and December 2016. Overall survival (OS) and progression-free survival (PFS) were analyzed. The predictive value of the ALBI grade was investigated. The prognostic nomogram was constructed using the independent predictors assessed by the multivariate Cox proportional hazards model. After a median follow-up of 35.0months (range, 4.0-221.0months), 380 patients had died. The median OS was 35.0months (95% confidence interval (CI), 30.84-39.16months), and the median PFS was 6.5months (95% CI, 6.13-6.87months). The ALBI grade was validated as an independent predictor of OS (p < 0.001). Multivariate analyses showed that Eastern Cooperative Oncology Group performance status score more than 0, presence of liver cirrhosis, a-fetoprotein level above 400ng/mL, tumor size greater than 5cm, tumor number more than 3, advanced ALBI grade, and treatment sessions of TACE or MWA fewer than 3 were independently associated with overall mortality. The prognostic nomogram incorporating these eight predictors achieved good calibration and discriminatory abilities with a concordance index of 0.770 (95% CI, 0.746-0.795). The prognostic nomogram based on the ALBI grade resulted in reliable efficacy for prediction of individualized OS in patients with intermediate-stage HCC after TACE-MWA. • TACE-MWA was associated with a median overall survival of 35.0months for patients with intermediate-stage HCC. • A prognostic nomogram was built to predict individualized survival of patients with intermediate-stage HCC after TACE-MWA. • The prognostic nomogram incorporating eight predictors achieved good calibration and discriminatory abilities with a concordance index of 0.770.

Why Cannot BCLC 0- or A-Stage Patients Receive Curative Treatment?

Introduction: Barcelona Clinic Liver Cancer (BCLC) staging has been an important clinical guideline for the management of hepatocellular carcinoma (HCC). BCLC 0 and A stages (BCLC 0/A) have been designated as the early-stage HCC, and the curative treatment is recommended as the primary therapeutic modality. However, a recent study indicated that a significant number of BCLC 0/A patients were not initially managed with the curative treatment without knowing why. Methods: We, therefore, conducted a study on BCLC 0/A patients who had and had not received initial curative treatment cared at our cancer center from January 2011 to December 2015 and analyzed causes contributing to not having the initial curative treatment. Results: One hundred and sixty-nine BCLC 0/A patients were identified and included in the study. Seventy two patients (43%) received the initial curative treatment and 97 patients (57%) did not. After careful review of medical records, all 97 patients without the initial curative treatment had identifiable reasons for not having the initial curative treatment. Two main reasons for not having the initial curative treatment were “probable presence of additional HCC and requiring diagnostic angiography” (28%) and “difficult or complicating anatomical location of tumors” (17%). When the relevant clinical parameters were compared between the 2 groups of patients, it was found that patients without the initial curative treatment had more serious clinical conditions and worse overall and recurrence-free survival outcomes compared with those who had the initial curative treatment. Discussion/Conclusion: Our finding indicates that a significant fraction of the BCLC 0/A HCC patients is unable to have initial curative treatment as recommended by BCLC guidelines. These early stages of HCC patients represent a distinctive subpopulation and are in need of further investigation to improve their survival outcomes.
