Abstract
PURPOSE To investigate imaging findings on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) and prognosis of clear cell hepatocellular carcinoma (CCHCC) comparing with non-otherwise specified hepatocellular carcinoma (NOS-HCC). METHODS The clinical, pathological and MR imaging features of 42 patients with CCHCC and 84 age-matched patients with NOS-HCC were retrospectively analyzed from January 2015 to October 2021. Univariate and multivariate logistic regression and Cox regression analyses were performed to identify independent diagnostic and prognostic factors for CCHCC. Disease-free survival (DFS) and overall survival (OS) were determined by Kaplan-Meier analysis. RESULTS CCHCC showed fat content more frequently (P < 0.001) and relatively higher Edmondson tumor grade (P = 0.001) compared with NOS-HCC. The lesion-to-muscle ratio (LMR) and lesion-to-liver ratio (LLR) of CCHCC on pre-enhancement T1-weighted imaging (pre-T1WI) (P = 0.001, P = 0.003) and hepatobiliary phase (HBP) (P = 0.007, P = 0.048) were significantly higher than those of NOS-HCC. The area under the curve (AUC) for fat content, LLR on pre-T1WI and their combination with better diagnostic performance in predicting CCHCC were 0.678, 0.666, and 0.750, respectively. There was no statistically significant difference in clinical outcomes between CCHCC and NOS-HCC. Multivariate Cox analysis confirmed that tumor size > 2 cm and enhancing capsule were independent prognostic factors for DFS and OS among CCHCC patients. CONCLUSION Fat content and adjusted lesion signal intensity on pre-T1WI and HBP could be used to differentiate CCHCC from NOS-HCC. CCHCC had similar prognosis with NOS-HCC.

Li Z, Hong Q, Li K. Nomogram predicting survival in patients with lymph node-negative hepatocellular carcinoma based on the SEER database and external validation. Eur J Gastroenterol Hepatol 2024; 36:904-915. [PMID: 38652516 PMCID: PMC11136272 DOI: 10.1097/meg.0000000000002756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 02/19/2024] [Indexed: 04/25/2024]
Abstract
BACKGROUND The relationship between lymph node (LN) status and survival outcome in hepatocellular carcinoma (HCC) is a highly controversial topic. The aim of this study was to investigate the prognostic factors in patients without LN metastasis (LNM) and to construct a nomogram to predict cancer-specific survival (CSS) in this group of patients. METHODS We screened 6840 eligible HCC patients in the Surveillance, Epidemiology and End Results(SEER)database between 2010 and 2019 and randomized them into a training cohort and an internal validation cohort, and recruited 160 patients from Zhongnan Hospital of Wuhan University as an external validation cohort. Independent prognostic factors obtained from univariate and multivariate analysis were used to construct a nomogram prediction model. The concordance index (C-index), area under curve (AUC), calibration plots and decision curve analysis (DCA) were used to assess the predictive power and clinical application of the model. RESULTS Univariate and multivariate analysis revealed age, gender, bone metastasis, lung metastasis, AFP, T stage, surgery and chemotherapy as independent prognostic factors. The C-index of the constructed nomogram for the training cohort, internal validation cohort and external validation cohort are 0.746, 0.740, and 0.777, respectively. In the training cohort, the AUC at 1-, 3-, and 5-year were 0.81, 0.800, and 0.800, respectively. Calibration curves showed great agreement between the actual observations and predictions for the three cohorts. The DCA results suggest that the nomogram model has more clinical application potential. CONCLUSION We constructed a nomogram to predict CSS in HCC patients without LNM. The model has been internally and externally validated to have excellent predictive performance and can help clinicians determine prognosis and make treatment decisions.

Primary spindle cell tumor originating from the liver that was difficult to diagnose. Surg Case Rep 2022; 8:171. [PMID: 36117227 PMCID: PMC9482895 DOI: 10.1186/s40792-022-01530-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 09/13/2022] [Indexed: 11/12/2022] Open
Abstract
Background It has been reported that hepatocellular carcinoma (HCC) with spindle cell tumor accounts for 1.8% of all HCCs, but spindle cell tumors that do not show an obvious conventional HCC are extremely rare. In this report, we describe a case of resection of a primary spindle cell tumor of the liver that was difficult to diagnose. Case presentation A 75-year-old man presented with fever and right chest pain. He was suspected of a giant primary diaphragmatic tumor of extrahepatic origin by imaging studies. The preoperative differential diagnosis included benign masses such as myxoid sarcoma and schwannoma, and we planned a diaphragmatic resection. Intraoperatively, however, dissection of the tumor from the liver was not possible, requiring an extended right posterior segmentectomy with combined resection of the diaphragm. The patient had a good postoperative course and 1 year has passed since the surgery with no recurrence. The pathology showed that the mass was located just below the hepatic capsule/parenchymal region and was adherent to the diaphragm, but there was no continuity. The morphology suggested a low-grade mesenchymal tumor such as a solitary fibrous tumor and perivascular epithelioid cell tumor, but immunostaining was negative, making the diagnosis difficult. Although some areas of high proliferative activity were observed, finally, the diagnosis of primary spindle cell tumor of the liver with smooth muscle differentiation was made based on the positive results of muscle markers such as αSMA, desmin, and h-caldesmon. Conclusions Spindle cell tumor arising from the liver is so rare that preoperative and pathological diagnosis is often difficult to reach. Although further studies are needed to elucidate and better understand this uncommon clinical entity, we consider that complete resection is necessary for the above case, which may contribute to long-term survival.

Abstract
BackgroundHepatocellular carcinoma (HCC) is a highly heterogeneous tumor with several rare pathological subtypes and which is still poorly understood. This study aimed to describe the epidemiological and clinical spectrum of five rare HCC subtypes and develop a competing risk nomogram for cancer-specific survival prediction.MethodsThe study cohort was recruited from the Surveillance, Epidemiology, and End Results database. The clinicopathological data of 50,218 patients histologically diagnosed with classic HCC and five rare subtypes (ICD-O-3 Histology Code = 8170/3-8175/3) between 2004 and 2018 were reviewed. The annual percent change (APC) was calculated utilizing Joinpoint regression. The nomogram was developed based on multivariable competing risk survival analyses. Akaike information criterion, Bayesian information criterion, C-index, calibration curve, and area under the receiver operating characteristic curve were obtained to evaluate the prognostic performance. A decision curve analysis was introduced to examine the clinical value of the models.ResultsDespite scirrhous carcinoma, which showed a decreasing trend (APC = -6.8%, P = 0.025), the morbidity of other rare subtypes remained stable from 2004 to 2018. The incidence-based mortality was plateau in all subtypes during the period. Clear cell carcinoma is the most common subtype (n = 551, 1.1%), followed by subtypes of fibrolamellar (n = 241, 0.5%), scirrhous (n = 82, 0.2%), spindle cell (n = 61, 0.1%), and pleomorphic (n = 17, ~0%). The patients with fibrolamellar carcinoma were younger and more likely to have a non-cirrhotic liver and better prognoses. Scirrhous carcinoma shared almost the same macro-clinical characteristics and outcomes as the classic HCC. Clear cell carcinoma tended to occur in the Asia-Pacific elderly male population, and more than half of them were large HCC (Size>5cm). Sarcomatoid (including spindle cell and pleomorphic) carcinoma was associated with a larger tumor size, poorer differentiation, and more dismal prognoses. The pathological subtype, T stage, M stage, surgery, alpha-fetoprotein, and cancer history were confirmed as the independent predictors in patients with rare subtypes. The nomogram showed good calibration, discrimination, and net benefits in clinical practice.ConclusionThe rare subtypes had unique clinicopathological features and biological behaviors compared with the classic HCC. Our findings could provide a valuable reference for clinicians. The constructed nomogram could predict the prognoses with good performance, which is meaningful to individualized management.

Abstract
Background Primary liver sarcomatoid carcinoma (PLSC) is rare. To improve the understanding of PLSC, cases were described and reviewing the literature. Methods A retrospective analysis was performed on 14 cases of PLSC diagnosed by pathology in Northeastern China from 2010 to 2020. An individual participant data analysis based on reported cases was conducted to determine epidemiological characteristics, clinical characteristics, and prognoses of PLSC. Results A total of 136 cases involved our 14 cases and 122 cases from previous reports. The percentages of sarcomatoid hepatocellular carcinoma, sarcomatoid cholangiolocellular carcinoma, and mixed and unclassified types were 36.8%, 41.9%, 5.9%, and 15.4%, respectively. A total of 95.6% PLSC was found in Asia. There was a lower percentage of hepatitis-infected patients in Japan, when compared with the Republic of Korea (38.5% vs 70.0%, P<0.05). Five cases were initially misdiagnosed as a hepatic abscess by imaging. A total of 36.7% cases had metastases when being diagnosed, and 68.9% cases relapsed during the follow-up. The median disease-free survival and overall survival (OS) were 3 months and 5 months, respectively. Only radical surgery (hazard ratio = 0.308, 95% confidence interval 0.186–0.512, P<0.001) indicated a better OS. Conclusion PLSC was more prevalent in Asia and there were possibilities of misdiagnoses. Surgery is still an effective treatment and can significantly prolong the OS. Only limited strategies for recurrent or advanced PLSC, immunotherapy may be possible treatment.

Abstract
BACKGROUND In the USA, fibrolamellar hepatocellular carcinoma (FLC) accounts for 1-2% of all cases of hepatocellular carcinoma. FLC remains poorly understood. AIM We aim to investigate the incidence, demographics, tumor characteristics, treatment, and prognosis of patients with FLC. METHODS Data on FLC between 2000 and 2016 were extracted from the SEER database and analyzed. RESULTS A total of 300 patients with FLC were identified where 126 were male. Median age at diagnosis was 27 ± 22 years. The overall age-adjusted incidence of FLC between 2000 and 2016 was 0.02 per 100,000 per year. A bimodal distribution was observed where the highest incidences occurred between 15-19 years and 70-74 years. Most tumors on presentation were moderately differentiated (20.7%), while the most common stage at presentation was stage 1 (21.7%) followed by stages 3 and 4 (20.0% and 20.3%, respectively); 50.3% of these tumors were surgically resected, while 8.0% received radiation and 45.3% received chemotherapy. One- and 5-year cause-specific survival for FLC was 72.0% and 32.9%, respectively, with a median survival of 32.9 months. HCC had a median survival time of 11.7 months. Patients who were not treated with surgical intervention had about 3 times increased risk for death (HR 2.8, 95% CI 1.68-4.72, P = 0.000). Radiation and chemotherapy did not significantly affect outcomes. CONCLUSION FLC presents with a bimodal distribution in both early and elderly individuals. Compared to HCC, FLC has a higher recurrence rate but better survival outcome. Surgical intervention is superior to chemotherapy and radiation.

Abstract
Worldwide, primary liver cancer is the fourth leading cause of cancer mortality. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Sarcomatoid hepatocellular carcinoma (SHC) is a rare subtype of HCC with conventional HCC admixed with areas with sarcomatoid morphology. SHC is an aggressive, rapidly growing tumor with unfavorable prognosis. Pedunculated SHC is an uncommon presentation of SHC. Due to its rarity, much remains unknown about the etiopathogenesis, molecular underpinnings, and treatment of SHC. We present a case of an exophytic SHC arising in a background of cirrhosis in an older adult. A resection was performed, but the patient subsequently developed multiple additional intrahepatic metastatic lesions necessitating further treatment with chemotherapy.

Abstract
Hepatocellular carcinoma (HCC) is a morphologically heterogeneous tumor with variable architectural growth patterns and several distinct histologic subtypes. Large-scale attempts have been made over the past decade to identify targetable genomic alterations in HCC; however, its translation into clinical personalized care remains a challenge to precision oncology. The role of pathology is no longer limited to confirmation of diagnosis when radiologic features are atypical. Pathology is now in a position to predict the underlying molecular alteration, prognosis, and behavior of HCC. This review outlines various aspects of histopathologic diagnosis and role of pathology in cutting-edge diagnostics of HCC.

Abstract
AIMS To establish and define a new, not previously reported hepatocellular carcinoma (HCC) variant, termed fibronodular HCC (FN-HCC). METHODS We retrospectively reviewed 290 HCC cases and identified 29 FN-HCC and 24 scirrhous HCC (SCHCC). Clinical, pathological and radiological features of FN-HCC were reviewed and compared with 30 conventional HCCs (CV-HCC) and SC-HCC. RESULTS FN-HCCs were more likely to arise in non-advanced fibrotic livers with lower advanced Barcelona Clinic Liver Cancer (BCLC) stage, had lower rates of progression and longer time to progression and were more likely to be surgically resected compared with CV-HCCs and SC-HCCs. Imaging analysis of FN-HCCs demonstrated higher rates of non-peripheral washout and a new distinct pattern of enhancement which is characterised by the presence of multiple rounded nodules within a lesion embedded in fibrotic-appearing parenchyma. CONCLUSIONS FN-HCC may represent a specific variant of HCC with distinct pathological, radiological and clinical features with potential ramifications for outcome.

Abstract
INTRODUCTION Scirrhous hepatocellular carcinoma (HCC) is a rare primary liver tumor characterized by extensive fibrosis and production of parathyroid hormone-related peptide. There have been conflicting reports on patient survival in scirrhous versus non-scirrhous HCC. The objective of the present study was to define the clinical features, practice patterns, and long-term outcomes of patients with scirrhous HCC versus non-scirrhous HCC in a propensity score-matched cohort. METHODS A propensity score-matched cohort was created using data from the National Cancer Database for 2004 to 2015. A multivariable Cox proportional hazards regression analysis was performed to assess the effect of the scirrhous HCC variant on overall survival. RESULTS Among the 70,426 patients with a diagnosis of HCC who met the inclusion criteria, 99.8% had non-scirrhous HCC (n = 70,290) whereas a small subset had scirrhous HCC (n = 136, 0.19%). While 20,330 (28.9%) patients underwent liver-directed therapy (resection, ablation, and transplantation), the majority did not (n = 50,096, 71.1%). After propensity matching, there were no difference in 1-, 3-, or 5-year overall survival among patients with scirrhous versus non-scirrhous HCC (1-year overall survival (OS), 53.7% versus 51.0%; 3-year OS, 34.6% versus 28.7%; and 5-year OS, 18.0% versus 21.0%, respectively; p = 0.52). While the scirrhous HCC variant was not associated with survival (hazard ratio [HR] 0.93, 95% CI 0.74-1.16), non-receipt of liver-directed therapy (HR 0.24, 95% CI 0.18-0.32), advanced AJCC stage (III/IV) (HR 2.14, 95% CI 1.55-2.95), and non-academic facilities (HR 0.60, 95% CI 0.49-0.73) remained associated with worse survival. CONCLUSION Patients with the scirrhous variant had a comparable overall survival compared with individuals who had non-scirrhous HCC. Failure to receive liver-directed therapy, advanced AJCC stage (III/IV), and treatment at a non-academic facility was strongly associated with a worse long-term prognosis.

Abstract
BACKGROUND Primary clear cell carcinoma of the liver (PCCCL) is an infrequent variant of primary hepatocellular carcinoma (HCC), we retrospectively performed a large population-based cohort study to elucidate the relationships between demographic, carcinoma- and therapy-specific variables and overall survival (OS). MATERIAL AND METHODS The Surveillance, Epidemiology and End Results (SEER) database was queried to extract data on 419 patients with pathologically confirmed PCCCL from 1988 to 2015. A nomogram with good accuracy was formulated to predict long-term survival of PCCCL patients. RESULTS The OS for PCCCL patients was 25.6 months (95% confidence interval [CI]: 22.2-29 months), the overall 1-year, 3-year, and 5-year survival rates were 59.5%, 39.3%, and 29.9%, respectively. Log-rank analysis revealed that there was no statistically significant discrepancy in clinical outcome between PCCCL and common-type HCC after propensity-matched analysis. Multivariate Cox analysis confirmed that larger lesions (>96 mm), distant metastases and elevated alpha-fetoprotein (AFP) levels were independent prognostic factors for undesirable outcome. Conversely, surgery was an independent protective factor (hazard ratio [HR]=0.23, 95% CI 0.17-0.31), which significantly boosted OS by virtually 35 months (47.3 months versus 12.7 months, P<0.001). Radiotherapy or chemotherapy was not associated with OS for PCCCL patients (both P>0.05). The nomogram incorporated 4 independent prognostic factors and its concordance index for predicting survival was 0.761. CONCLUSIONS The prognosis of PCCCL resembled that of common-type HCC. Larger lesions, distant metastases, and enhanced AFP levels were associated with unsatisfactory prognosis. Surgery fulfill favorable prognosis while radiotherapy or chemotherapy exerted no significant effects on survival.

Abstract
Background HCC variants are rare primary hepatic tumors. The aim of this study is to compare clinical characteristics and outcomes of HCC variants with pure HCC. Methods Patients diagnosed between 2004 and 2013 with ICD-O-3 8180/3 and 8170/3-8175/3 were identified from the National Cancer Database. Univariate and multivariate survival analyses were conducted to analyze the association between histology and overall survival (OS). Results 80,280 patients were identified; pure HCC 78,461 (97.7%), fibrolamellar (FLHCC) 310 (0.4%), scirrhous 161 (0.2%), spindle cell 72 (0.1%), clear cell 487 (0.6%), pleomorphic 23 (0.0%), and combined HCC and cholangiocarcinoma (mixed HCC) 766 (1.0%). 76.7% were male and 72% Caucasian. Liver transplant was performed in 10.1% of pure HCC, 14.5% of mixed HCC, 16.2% of scirrhous, 6.9% of spindle cell, 8.8% of clear cell, 8.7% of pleomorphic, and 3.2% of FLHCC (p<0.001). Pure HCC (10.6%) underwent surgical resection without transplant less often than variants except for scirrhous (9.9%) (p<0.001). More than a third of patients in each histological type received chemotherapy. FLHCC had the best 5-year OS (38.7%), spindle cell and pleomorphic had the worst (9.6% and 13.0%). In multivariate analysis stratified by histology variants, chemotherapy was associated with improved OS in all histologies except for scirrhous and pleomorphic HCC. Conclusion HCC variants underwent surgical resection more often than pure HCC. FLHCC had the best 5-year OS. Liver transplant was commonly performed in HCC variants.

Management and outcomes among patients with sarcomatoid hepatocellular carcinoma: A population-based analysis. Cancer 2019; 125:3767-3775. [PMID: 31299092 DOI: 10.1002/cncr.32396] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 06/04/2019] [Accepted: 06/19/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Few data are available regarding the management and outcomes among patients with sarcomatoid hepatocellular carcinoma (HCC) due to its rarity. METHODS Patients diagnosed with sarcomatoid HCC from 2004 through 2015 were identified in the National Cancer Data Base. Overall survival (OS) was calculated among patients with sarcomatoid versus conventional HCC using a 1:3 propensity score matching based on sex, age, and American Joint Committee on Cancer (AJCC) stage of disease. RESULTS The final analytic cohort included 104 patients with sarcomatoid HCC and 312 patients with conventional HCC. Patients with sarcomatoid HCC more often had a larger median tumor size (8.5 cm vs 5.4 cm; P < .001) and poorly or undifferentiated tumors (52.9% vs 13.8%; P < .001) compared with patients who had conventional HCC. 5-year OS was worse among patients with sarcomatoid versus conventional HCC (5.7% vs 30.1%; P < .001). Subgroup analysis demonstrated worse 5-year OS among patients with sarcomatoid versus conventional HCC among patients treated with either curative-intent or palliative therapies. Stage-specific subgroup analysis indicated a worse OS among patients with AJCC stage I, stage II, or stage III sarcomatoid HCC. On multivariable analysis, uninsured status, advanced AJCC stage (stage III/stage IV), and histological sarcomatoid subtype were independently associated with worse outcomes (all P < .05). CONCLUSIONS Sarcomatoid HCC is a very rare variant of HCC, which was associated with larger tumor size and worse tumor grade on presentation. On propensity score matched analyses that controlled for known confounding factors, patients with sarcomatoid HCC had a worse stage-for-stage long-term survival compared with patients who had conventional HCC.

Abstract
Data warehousing is the most important technology to address recent advances in precision medicine. However, a generic clinical data warehouse does not address unstructured and insufficient data. In precision medicine, it is essential to develop a platform that can collect and utilize data. Data were collected from electronic medical records, genomic sequences, tumor biopsy specimens, and national cancer control initiative databases in the National Cancer Center (NCC), Korea. Data were de-identified and stored in a safe and independent space. Unstructured clinical data were standardized and incorporated into cancer registries and linked to cancer genome sequences and tumor biopsy specimens. Finally, national cancer control initiative data from the public domain were independently organized and linked to cancer registries. We constructed a system for integrating and providing various cancer data called the Korea Cancer Big Data Platform (K-CBP). Although the K-CBP could be used for cancer research, the legal and regulatory aspects of data distribution and usage need to be addressed first. Nonetheless, the system will continue collecting data from cancer-related resources that will hopefully facilitate precision-based research.

Abstract
Background Clinicopathological features and the outcomes of patients with fibrolamellar hepatocellular carcinoma (FLHCC) are not clearly defined. Methods Data were collected by retrospective chart review on 42 patients with FLHCC treated between 1990 and 2017 at Mayo Clinic. Results Of 42 patients (median age at diagnosis 22 years), 10 patients (23.8%) had stage I disease and 32 patients (76.2%) had stage II to IVB disease. All 10 patients with stage I disease and 21 of 32 patients with stage II-IVB disease underwent resection at presentation. In stage I patient group, 6 patients experienced recurrence with a median time to recurrence of 30.5 months and a 5-year overall survival (OS) of 86%. Patients with stage II to IVB disease who underwent resection (n=21) upfront had a median OS of 32.5 months and 5-year OS of 44%. In the upfront surgery group, 71% of patients experienced recurrence. The median OS of patients with unresectable disease (n=11) was 10 months. Four out of nine patients treated with sorafenib had stable disease and one patient with programmed cell death ligand-1 (PD-L1) expressing tumor had a near complete response after 2 months of therapy with nivolumab. Conclusions In FLHCC, surgical resection was associated with prolonged OS; although most patients had a disease recurrence regardless of disease stage and resection margin status. The response to kinase inhibitor, sorafenib, was variable. In select cases, therapy with a checkpoint inhibitor may provide a viable treatment option.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second leading cause of cancer-related deaths worldwide. Sarcomatoid HCC is a rare histological subtype of HCC with largely unclear clinical manifestations and outcomes. We evaluated the clinical manifestations and outcomes of patients with sarcomatoid HCC. We identified 5,047 patients with histologically proven HCC from the Cancer Registry Database (1996-2016) of National Taiwan University Hospital. Among them, 40 patients with sarcomatoid HCC were identified from the pathology database of National Taiwan University Hospital. We included 160 patients with nonsarcomatoid HCC through propensity score matching according to sex, age, and Barcelona Clinic Liver Cancer stage. The majority of these patients with sarcomatoid HCC were men (75%); their median age was 58 years. Only 47.5% of the patients with sarcomatoid HCC presented with typical image patterns of HCC. The pathological grading of sarcomatoid HCC was more advanced compared with that of nonsarcomatoid HCC (42.5% vs. 23.8% in grade III and IV, P < 0.0001). The sarcomatoid group had significantly shorter median recurrence-free (13.3 vs. 84.2 months, log-rank P < 0.0001) and overall (8.3 vs. 69.3 months, log-rank P < 0.0001) survival than did the nonsarcomatoid group. The results of the multivariable Cox proportional hazard model revealed histological sarcomatoid subtype as an independent factor for all-cause mortality (hazard ratio [HR], 6.47; 95% confidence interval [CI], 3.12-13.43; P < 0.0001) and tumor recurrence (HR, 4.08; 95% CI, 1.72-9.66; P = 0.001). Conclusion: Compared with nonsarcomatoid HCC, sarcomatoid HCC was associated with more advanced histological grades and atypical image patterns. Histological sarcomatoid subtype is an independent predictor of tumor recurrence after curative treatment and all-cause mortality in patients with HCC.

Abstract
OBJECTIVE This study aimed to analyze clinicopathological and prognostic features of four rare pathological subtypes of primary liver malignancies to make better understanding of their clinical features. METHODS The clinicopathological data of 114 patients who were diagnosed with histologically proven four subtypes: clear cell carcinoma (CCC), giant cell carcinoma (GCC), sarcomatoid carcinoma (SC), and combined hepatocellular-cholangiocarcinoma (CHC) between October 1998 and August 2015 were reviewed. Their survival data were compared with those of 908 patients with histologically proven common hepatocellular carcinoma (HCC) (early- and advanced-stage HCC) during the same period. RESULTS The outcome of the CCC group was better than that of the other three subgroups, and was similar to that of the early-stage HCC group. Also, the smallest tumor size and the highest incidence of pseudocapsule formation were observed in the CCC group. The SC group had the worst outcome among these four subgroups; the prognosis was much poorer than that of any other subgroups, even poorer than that of the advanced-stage common HCC group. No statistical difference was observed between the GCC, CHC and advanced-stage HCC groups on survival analysis. The incidences of tumor vascular emboli, TNM staging and non-radical resection were three risk factors of the prognosis. CONCLUSIONS CCC is a low-degree malignancy and relatively favorably prognostic subtype of HCC. However, GCC, SC, and CHC are three rare high-degree malignancy subtypes of HCC with poor prognosis.

Abstract
BACKGROUND Primary liver cancer, including Hepatoblastoma (HB) and hepatocellular carcinoma (HCC), in pediatric populations is often fatal. The outcomes are poor despite universal health care access in pediatric patients. AIM We investigated the sociodemographic factors affecting outcomes in pediatric patients with primary liver cancer. MATERIALS AND METHODS This is a large population database study of Surveillance, Epidemiology, and End Results cancer registry data from 1973 to 2011. HB and HCC were analyzed regarding age, sex, race, geographic area, and treatment-related information including survival. RESULTS In total, 998 patients, the median age at time of diagnosis was 1 year for HB [0-19; 95% confidence interval (CI), 1.5-1.9] and 14 years for HCC (0-19; 95% CI, 12.1-13.3) (P<0.001). Overall Survival (OS) in HB was 374 months (25% failures 19) versus HCC 21 months (25% failures 5; P<0.0001). In HCC, the fibrolamellar subgroup OS was 41 months (32-.) versus 16 months (11-21) in all others [hazard ratio (HR) 2.0; P=0.005]. Diagnosis between 2000 and 2011 (HB: 25% failures not reached; HCC: 38) versus diagnosis 1973 to 1999 (HB: 374; HCC: 12) had different survival (P=0.01; HR 1.9). For HB, OS in patients with age of diagnosis under 2, 25% failures was not reached versus 374 months over the age of 2 (HR 1.7; P<0.0007). African American children with HB had OS of 67 (17-.) versus all others (25% failures 21) and 48% of African American children were diagnosed after the age of 2 versus 34% of whites (HR 1.9; P=0.01). CONCLUSIONS Later diagnosis and decreased survival in African American children with HB warrants further research.

Abstract
Fibrolamellar hepatocellular carcinoma is a rare form of hepatocellullar cancer seen in younger patients without underlying liver disease. Liver resection with lymph node dissection is the mainstay of treatment. Bile duct tumor thrombus that has been reported in hepatocellular cancer has to date never been described in fibrolamellar hepatocellular cancer and must be a consideration in patients who present with obstructive jaundice.
Background Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare and unique variant of hepatocellular carcinoma (HCC) whose presentation remains inadequately described. We present a resectable case of FL-HCC which involved tumor thrombus of the common bile duct. Presentation A 27 year-old male presenting with jaundice, abdominal pain, vomiting, hepatic dysfunction and hyperbilirubinemia was found to have a large liver mass and lymphadenopathy on preoperative imaging. A right hepatectomy with perihepatic lymph node dissection and cholecystectomy was performed. Intraoperative cholangiogram demonstrated common bile duct (CBD) obstruction. CBD exploration revealed biliary tumor thrombus relieved with biliary thrombectomy. Discussion FL-HCC can initially present with invading obstructing biliary tumor thrombus of the CBD causing jaundice. Conclusion Preoperative surgical approach should consider CBD exploration on an individual basis for underlying obstructive biliary tumor thrombus.
