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.

Naganuma H, Ishida H. Hepatocellular Carcinoma in Non-Fibrotic Liver: A Narrative Review. Diagnostics (Basel) 2023; 13:3426. [PMID: 37998562 PMCID: PMC10670297 DOI: 10.3390/diagnostics13223426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 11/08/2023] [Accepted: 11/09/2023] [Indexed: 11/25/2023] Open
Abstract
Hepatocellular carcinoma (HCC) in a non-fibrotic liver (F0) is considered to be rare, and there is a marked paucity of studies in the literature on this HCC type. A review of the literature shows some important clinical and tumor characteristics: (a) it occurs mainly in young female and elder male patients; (b) clinically, under normal hepatic function, alpha-fetoprotein level is often normal, and there are no risk factors; (c) associated with metabolic disease; (d) macroscopically, single large lesions are noted; and (e) microscopically, the lesions are well-differentiated and encapsulated. Radiological imaging results are straightforward, showing arterial hyperenhancement and later wash-out. The combined use of B-mode and contrast-enhanced (CE) ultrasound (US) is the most reliable and cost-effective diagnostic method. Few peri-and post-operative complications are noted and 5-year survival is not inferior to patients with HCC on fibrosis liver despite the lesion's large size. Most clinicians believe that HCC is unlikely to occur if patients have no symptoms and normal hepatic function. Although detailed clinical data are very limited, we expect that this review will help to improve the clinical management of HCC in non-fibrotic livers.

Abstract
There are few case reports of hepatocellular carcinoma (HCC) metastasis to the skeletal muscle. A 78-year-old man developed a mass in the right shoulder. Washout of contrast medium during contrast-enhanced ultrasonography (CEUS) in both the primary HCC and the metastatic site was detected. Several nodules were scattered throughout the liver on an autopsy. In addition, the moderately differentiated HCC had metastasized to the right teres major muscle. Rare muscular metastasis should be considered if a hepatic tumor is moderately or poorly differentiated HCC. Early washout during CEUS is consistent with a pathological diagnosis of moderately or poorly differentiated HCC.

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
Clear cell hepatocellular carcinoma (CHCC) is defined as a tumor which contains more than 50% of clear cells. However, CHCC with more than 90% of clear cells are extremely rare. We report a case of a 65-year-old woman who was found to have a solitary mass, which was histologically diagnosed as clear cell hepatocellular carcinoma composed of 90% or more clear cells. The tumor presented rim arterial phase hyperenhancement in computed tomography, magnetic resonance imaging, and computed tomography during hepatic arteriography, and was classified as LR-M category according to The Liver Imaging Reporting and Data System version 2018(LI-RADS v2018). This tumor may mimic other tumors with similar radiographic features, such as intrahepatic cholangiocellular carcinoma and metastatic tumor.

Abstract
Histopathologic diversity and several distinct histologic subtypes of hepatocellular carcinoma (HCC) are well-recognized. Recent advances in molecular pathology and growing knowledge about the biology associated with distinct histologic features and immuno-profile in HCC allowed pathologists to update classifications. Improving sub-classification will allow for more clinically relevant diagnoses and may allow for stratification into biologically meaningful subgroups. Therefore, immuno-histochemical and molecular testing are not only diagnostically useful, but also are being incorporated as crucial components in predicting prognosis of the patients with HCC. Possibilities of targeted therapy are being explored in HCC, and it will be important for pathologists to provide any data that may be valuable from a theranostic perspective. Herein, we review and provide updates regarding the pathologic sub-classification of HCC. Pathologic diagnostic approach and the role of biomarkers as prognosticators are reviewed. Further, the histopathology of four particular subtypes of HCC: Steatohepatitic, clear cell, fibrolamellar and scirrhous - and their clinical relevance, and the recent consensus on combined HCC-cholangiocarcinoma is summarized. Finally, emerging novel biomarkers and new approaches to HCC stratification are reviewed.

Abstract
Primary clear cell carcinoma of liver (PCCCL) is an uncommon variant of primary hepatocellular carcinoma. Though the literature describes a better prognosis in relation to the proportion of clear cells in the tumour when compared to the other variants, there is no general consensus in the management due to its rarity and unclear clinicopathological and prognostic factors. There is dearth of evidence with regard to the metastasizing nature of PCCCL and its management. In addition, the management of recurrent spinal tumours both primary and metastatic is not clear as the available evidence is mostly based on case reports. We describe an unusual presentation of PCCCL with solitary spinal metastasis and further complicated by tumour recurrence in a 71-year-old male. Such presentation has never been described before. He presented with low back pain and incomplete neurological deficits involving both lower limbs. On detailed evaluation, he was found to have a solitary metastasis at L3 vertebra secondary to PCCCL. He underwent radical excision of tumour and reconstruction for the solitary metastasis at L3 vertebral body and trans arterial chemo embolisation (TACE) for the hepatic lesion. Pt was asymptomatic until 9 months post operatively when he developed tumour recurrence at L3 vertebra. Patient subsequently underwent 2 stage palliative surgery followed by radiotherapy and chemotherapy. At his latest follow-up (1 year), the patient's overall general condition has improved with residual neurological deficits in the lower limb. PCCCL is a rare type of hepatocellular carcinoma which can present as "solitary metastasis" to the spine. Although the literature suggests a good prognosis for this histological type, this case did not have a good outcome. In addition to providing information for the management of similar cases in the future, this case report highlights that every patient has to be managed on a case-by-case basis.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide and the incidence is increasing as a result of growing hepatitis B and C virus infections. Primary clear cell carcinoma of the liver (PCCCL) is a rare subgroup of primary HCC, which has low metastatic potential and infrequently reported in literature. Retroperitoneal and intrahepatic metastasis of PCCCL has not been reported previously. CASE SUMMARY Here, we present a 55-year-old male with retroperitoneal and intrahepatic metastasis of PCCCL who is managed with surgical method and transcatheter arterial chemoembolization (TACE) at our institution. When the patient is followed up in 16 months after surgery and TACE, he is alive without any extrahepatic metastasis and abnomal liver function. CONCLUSION We concluded that surgical resection of retroperitoneal metastasis and TACE of the intrahepatic tumors provided an appropriate strategy for the patient with unresectable PCCCL accompanied with extra-hepatic metastasis.

Abstract
Background Liver cancer is the second leading cause of cancer death in men worldwide. Hepatocellular carcinoma usually develops in the setting of cirrhosis or chronic inflammation. Major risk factors for developing hepatocellular carcinoma are chronic hepatitis B or C virus infection, alcoholic cirrhosis, and nonalcoholic fatty liver disease. The most frequent locations for hepatocellular carcinoma to metastasize are the lungs, portal vein, bones, and regional lymph nodes. Case presentation A 41-year-old Sri Lankan man presented with progressive abdominal distension and on examination was found to have a palpable irregular mass in the left lobe of his liver with moderate ascites. His ascitic fluid was an exudate without malignant cells. An ultrasound scan and contrast-enhanced computed tomography of his abdomen showed a large contrast-enhancing lesion in the left lobe of his liver without features of cirrhosis. Laparoscopic assessment revealed peritoneal and omental deposits. Histology of the biopsies taken from the liver lesion, omental deposits, and peritoneal deposits supported a diagnosis of hepatocellular carcinoma. His liver biochemistry was normal and hepatitis serology was negative. He is abstinent from alcohol and did not have metabolic syndrome. Conclusions It is rare for a young patient to develop hepatocellular carcinoma with a normal liver without chronic hepatitis B or C infection, or any other risk factors. Intraperitoneal metastasis of non-ruptured hepatocellular carcinoma is also very rare. Here we report a rare case of a 41-year-old man with a large hepatocellular carcinoma in a non-cirrhotic liver without chronic hepatitis who presented with peritoneal and omental metastasis.

Abstract
In the mammalian liver, 60 % of the cellular components are hepatocytes while the remainder (35 %) includes biliary epithelium, Kupffer cells, endothelial cells, fat storing cells and connective tissue cells. Although neoplasms of hepatocytes are the most common, a significant number of both benign and malignant primary liver neoplasms arising from other cell types can develop, such as tumors of bile duct epithelium (Table 1). In addition, the liver is one of the most susceptible sites for metastatic tumors arising from other organs of the body. Not too long ago, liver tumors were left untreated because the liver was considered a complex and mysterious organ inaccessible to surgery. Advances in imaging procedures and surgical techniques over the past 40 years have revolutionized the approaches to the treatment of benign and malignant liver tumors. Subsegmentectomy, segmentectomy, lobectomy, and transplantation are routinely performed for the treatment of primary and metastatic liver tumors with minimal morbidity and mortality. Since accurate diagnosis remains the key to clinical and surgical management, the emphasis of this chapter is on classification, morphological features and differential diagnosis of malignant neoplasms of the liver.

Abstract
Clear cell adenocarcinoma of the cervix is a rare tumor of the lower genital tract. It has been described in young women with a history of intra uterine exposure to diethylstilbestrol. This tumor is characterized by a greater tendency for late recurrences. In this article, we report the case of one exposed-patient who developed recurrence as liver metastases, 24 years after the initial treatment. This case demonstrates the need and the importance for continued follow-up in individuals prenatally exposed to diethylstilbestrol.

Abstract
PURPOSE To analyze CT characteristics of primary clear cell carcinoma of the liver (PCCCL) and improve the current understanding and diagnose accuracy of the tumor. METHODS Pre- and post-contrast CT images of 19 patients with pathology proven PCCCL were retrospectively analyzed. The clinical data and CT findings as well as relevant literature reports were reviewed. RESULTS Thirteen patients were tested positive for HBsAg, and two patients were positive for HCVAb. The serum alpha-fetoprotein (AFP) levels of most tumors (14/19) were ≤20 ng/ml with 14 cases were associated with liver cirrhosis. All lesions were solitary intraparenchymal mass lesions which have well-defined boarders. On pre-contrast CT scans, 15 lesions appeared as hypo-attenuation and four lesions appeared as isointensity to the adjacent liver parenchyma. On post-contrast CT scans, 16 lesions showed avid enhancement on the hepatic arterial phase, of which 6 lesions were hypo-attenuation, and 10 lesions remained slightly hyper-attenuation or iso-attenuation on the portal venous phase images. Three lesions showed only mild enhancement on the hepatic arterial phase and hypo-attenuation on the portal venous phase. All lesions demonstrated hypointensity on the equilibrium phase. There are 12 lesions showed pseudocapsules. None of patients showed signs of portal vein thrombosis. There was no distal metastasis except only one patient had lymph node metastasis. CONCLUSION The characteristics of CT imaging of PCCCL, such as tend to form pseudocapsules and less involved with vascular invasion, could be useful in differentiating from common type hepatocellular carcinoma (CHCC). Some CT imaging characteristics of PCCCL are similar to CHCC, such as prone to occur in patients with liver cirrhosis and early enhancement pattern on the hepatic arterial phase as well as hypo-attenuation on the equilibrium phase. Those features could be useful in differentiating PCCCL from other liver tumors, such as hemangioma and hepatic metastases.

Abstract
AIM: To investigate the clinicopathologic characteristics and prognostic factors of primary clear cell carcinoma of the liver (PCCCL).
METHODS: The clinical data for 15 PCCCL patients treated by curative resection from January 1997 to March 2007 were retrospectively analyzed.
RESULTS: The 1-, 3-, and 5-year overall survival (OS) rates of PCCCL patients were 97%, 60% and 60%, respectively. Tumor size was an independent risk factor for disease-free survival (DFS) of PCCCL, while tumor differentiation was an independent risk factor for OS of PCCCL.
CONCLUSION: PCCCL is an uncommon subtype of HCC, and complete surgical resection is the optimal treatment for PCCCL. The prognosis of PCCCL is better than that of other types of HCC.

Abstract
AIM: To retrospectively analyze the computed tomography (CT) and magnetic resonance imaging (MRI) appearances of primary clear cell carcinoma of the liver (PCCCL) and compare the imaging appearances of PCCCL and common type hepatocellular carcinoma (CHCC) to determine whether any differences exist between the two groups.
METHODS: Twenty cases with pathologically proven PCCCL and 127 cases with CHCC in the Second Affiliated Hospital of Sun Yat-sen University were included in this study. CT or MRI images from these patients were retrospectively analyzed. The following imaging findings were reviewed: the presence of liver cirrhosis, tumor size, the enhancement pattern on dynamic contrast scanning, the presence of pseudo capsules, tumor rupture, portal vein thrombosis and lymph node metastasis.
RESULTS: Both PCCCL and CHCC were prone to occur in patients with liver cirrhosis, the association rate of liver cirrhosis was 80.0% and 78.7%, respectively (P > 0.05). The mean sizes of PCCCL and CHCC tumors were (7.28 ± 4.25) cm and (6.96 ± 3.98) cm, respectively. Small HCCs were found in 25.0% (5/20) of PCCCL and 19.7% (25/127) of CHCC cases. No significant differences in mean size and ratio of small HCCs were found between the two groups (P = 0.658 and 0.803, respectively). Compared with CHCC patients, PCCCL patients were more prone to form pseudo capsules (49.6% vs 75.0%, P = 0.034). Tumor rupture, typical HCC enhancement patterns and portal vein tumor thrombosis were detected in 15.0% (3/20), 72.2% (13/18) and 20.0% (4/20) of patients with PCCCL and 3.1% (4/127), 83.6% (97/116) and 17.3% (22/127) of patients with CHCC, respectively. There were no significant differences between the two groups (all P > 0.05). No patients with PCCCL and 2.4% (3/127) of patients with CHCC showed signs of lymph node metastasis (P > 0.05).
CONCLUSION: The imaging characteristics of PCCCL are similar to those of CHCC and could be useful for differentiating these from other liver tumors (such as hemangioma and hepatic metastases). PCCCLs are more prone than CHCCs to form pseudo capsules.

Abstract
A wide variety of hepatic lesions contain fat within them in a proportion good enough to be demonstrable on imaging. With the biological behaviors quite different from each other, they form a clinico-radio-pathologic spectrum worth remembering. We present a review of common and uncommon focal hepatic lesions containing fat (micro- and macroscopic) within them and emphasize the role of imaging in their diagnosis.

Abstract
AIM: To clarify the therapeutic strategies and prognosis factors of primary clear cell carcinoma of the liver (PCCCL).
METHODS: The clinical pathological data of 64 patients with PCCCL treated with hepatectomy in our hospital from January 2000 to January 2006 were analyzed retrospectively. The patients were divided into two groups to make treatment analysis: curative resection only (n = 40); and curative resection and postoperative chemotherapy with calcium folinate and tegafur (n = 24). Meanwhile, the PCCCL patients were subdivided into two subgroups on the basis of the proportion of clear cells in the tumor for pathological analysis. There were 36 cases in subgroup A for which the proportion of clear cells was more than 70%, and 28 cases in subgroup B for which the proportion was less or equal to 70%, comparing analysis of median survival time of the counterpart groups. Univariate and multivariate analyses were performed to examine factors that affected clinical prognosis, recurrence and metastasis.
RESULTS: Median survival period of the curative surgery group was 38 mo, while the counterpart was 41 mo. Median survival period for group A was 41 mo, while group B was 19 mo. The Kaplan-Meier method showed that capsule formation, preoperative liver function, hepatitis C virus infection, large vascular invasion and multiple tumor occurrences were related to disease-free survival. Cox regression analysis showed that the clear cell ratio, capsule formation, preoperative liver function and large vascular invasion were independent risk factors for overall survival.
CONCLUSION: Postoperative chemotherapy has no obvious effect on survival of patients with PCCCL. Clear cell ratio, capsule formation, preoperative liver function, and vascular invasion were independent risk factors for prognosis.
