Abstract
AIMS To evaluate stromal histopathological features and immunostaining expression for differential diagnosis of low- and high-grade dysplastic nodules (HGDN) to early and progressed hepatocellular carcinomas (eHCC, pHCC). MATERIALS We evaluated sinusoid capillarisation (SC), solitary artery (SA), ductular reaction (DR), stromal invasion and expression of six biomarkers (GPC3, HSP70, GS, CD34, CK19, EpCAM) in a series of 97 cases. RESULTS Stromal morphological changes, including SC, DR and SA, exhibited significant differences in differential diagnosis. In one indicator, SC had the best sensitivity (90.00%) and accuracy (85.42%), and SA had the best specificity at 88.89 %. In combinations, SC +and SA +were favourable and optimal. The immunoreactivity of GPC3, HSP70 and GS increased significantly in line with the stepwise progression of hepatocarcinogenesis. CONCLUSIONS Stromal histopathology features are useful for diagnosing HGDN, eHCC and small HCC. The immunostaining panel of GPC3, HSP70 and GS can also be supplementary.

Hum Pathol 2018; 80:130-137. [PMID: 29936057 DOI: 10.1016/j.humpath.2018.06.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2018] [Revised: 05/26/2018] [Accepted: 06/09/2018] [Indexed: 12/11/2022]
Abstract
Small HCCs, including seHCC and spHCC, are rarely encountered in daily practice. Definite diagnosis is difficult for general pathologists. In this study, we reviewed 1025 cases of HCC and examined the histologic characteristics of small HCCs to facilitate more accurate diagnosis. Slides of archived HCC cases were reviewed by 2 senior pathologists, and small HCCs were identified according to the canonical criteria. Additional immunohistochemical stains were performed. Thirty-seven cases of small HCC were identified, including 22 cases of seHCC and 15 cases of spHCC. We found 2 types of invasive growth patterns in these lesions. The first is the expansile invasive growth pattern, with monomorphic tumor cells penetrating through the incomplete fibrous capsules and expanding into the adjacent noncancerous liver with a spherical, hemispheric, or mushroom shape. The second is the classic stromal invasion pattern. At least one type of invasive pattern was observed in all of the 37 cases of small HCC, and the seHCCs exhibit the expansile invasive growth pattern more frequently than the classic stromal invasion pattern. On the contrary, stromal invasive pattern was more common in spHCC nodules. In conclusion, with the background of chronic hepatitis and cirrhosis, histologic features including crowdedness of hepatocytic trabeculae and the expansile invasive growth pattern are strong evidence for the diagnoses of small HCC.

Abstract
AIM We aimed to assess the clinicopathological relevance and prognostic significance of expression of the hepatic progenitor cell markers keratin 19 (K19), epithelial cell adhesion molecule (EpCAM) and CD117 (c-KIT) in a White series of hepatocellular carcinoma (HCC). METHODS We evaluated the immunohistochemical expression of K19, EpCAM and CD117 in 89 surgical specimens of HCC from Greek patients (mean age 66.7±11.3 years, male 75.2%) followed up for 39.6±25.3 months. RESULTS K19, EpCAM and CD117 expression was detected in tumour cells of 10.11, 15.38 and 3.7% HCCs, respectively. Female sex was correlated with EpCAM immunohistochemical expression (P=0.035), whereas no other significant relationship with clinicopathological parameters was observed. K19 positivity tended to be correlated with microvascular invasion (P=0.054). In univariate analysis, K19 positivity and microvascular invasion were found to be associated with decreased recurrence-free survival (P<0.001 and P=0.004, respectively) and overall survival (P=0.002 and P=0.029, respectively). EpCAM and CD117 positivity was not correlated with patient survival. In multivariate analysis, K19 positivity emerged as an independent predictor of recurrence-free survival (odds ratio=7.84, 95% confidence interval=2.658-22.912, P<0.001) and overall survival (odds ratio=3.845, 95% confidence interval=1.401-10.549, P=0.009). CONCLUSION Our study confirms the prognostic significance of K19 expression in Caucasian patients with HCCs, providing further evidence that it may be used to stratify HCC according to tumour aggressiveness.

Abstract
Hepatocellular carcinoma (HCC) is the most rapidly increasing type of cancer in the United States. HCC is a highly malignant cancer, accounting for at least 14000 deaths in the United States annually, and it ranks third as a cause of cancer mortality in men. One major difficulty is that most patients with HCC are diagnosed when the disease is already at an advanced stage, and the cancer cannot be surgically removed. Furthermore, because almost all patients have cirrhosis, neither chemotherapy nor major resections are well tolerated. Clearly there is need of a multidisciplinary approach for the management of HCC. For example, there is a need for better understanding of the fundamental etiologic mechanisms that are involved in hepatocarcinogenesis, which could lead to the development of successful preventive and therapeutic modalities. It is also essential to define the cellular and molecular bases for malignant transformation of hepatocytes. Such knowledge would: (1) greatly facilitate the identification of patients at risk; (2) prompt efforts to decrease risk factors; and (3) improve surveillance and early diagnosis through diagnostic imaging modalities. Possible benefits extend also to the clinical management of this disease. Because there are many factors involved in pathogenesis of HCC, this paper reviews a multidisciplinary perspective of recent advances in basic and clinical understanding of HCC that include: molecular hepatocarcinogenesis, non-invasive diagnostics modalities, diagnostic pathology, surgical modality, transplantation, local therapy and oncological/target therapeutics.

Abstract
Hepatocellular carcinoma can be diagnosed on a needle biopsy of the liver; however, uncertainty may arise because of the inherent complexity of liver histology. This article aims to provide practicing pathologists with tools for the approach to mass-directed liver biopsies clinically concerning for hepatocellular carcinoma. The examination of routine hematoxylin-eosin stains and the use of ancillary histochemical and immunohistochemical stains are discussed. Sections reviewing liver carcinoma with biphenotypic differentiation and the challenge of dysplastic nodules are included.

Abstract
OBJECTIVES Cytokeratin 19 is significant for indicating cancer cells, and Cyfra 21-1 is a fragment of cytokeratin 19. This retrospective study was designed to define the prognostic value of serum Cyfra 21-1 in epithelial ovarian cancers (EOC). MATERIALS AND METHODS Serum Cyfra 21-1 concentration was obtained from 42 patients with EOC prior to treatment. Various prognostic aspects were examined using univariable and multivariable analyses. The standard serum marker cancer antigen 125 was measured simultaneously and compared in this analysis. RESULTS Serum levels of both Cyfra 21-1 and cancer antigen 125 were associated with positive retroperitoneal lymph nodes and platinum resistance; higher levels of Cyfra 21-1 (3.0 ng/mL as the cut-off) were associated with shorter disease-free survival (16 months vs. 28 months, p = 0.001) and overall survival (29 months vs. 41 months, p = 0.007) than lower levels. Further univariable analysis showed that Cyfra 21-1, poor differentiation, and retroperitoneal lymph node metastasis were related to platinum resistance and mortality. Multivariable analysis indicated retroperitoneal lymph node metastasis and serum Cyfra 21-1 were independent risk factors for both disease-free survival and overall survival. CONCLUSION The pretreatment level of serum Cyfra 21-1 had remarkable prognostic significance for EOC, indicating poor survival when it was elevated above 3.0 ng/mL.

Proliferative ductular reactions correlate with hepatic progenitor cell and predict recurrence in HCC patients after curative resection. Cell Biosci 2014; 4:50.

Abstract
Background Ductular reactions (DRs) are well documented in many acute and chronic liver disease.The DRs are thought to be the transit amplifying cells deriving from activation of the stem/progenitor cell compartments of the liver. The aim of this study was to examine the presence of proliferative index of DR (PI-DR) and HPC markers’ expression in HCCs after curative hepatectomy, as well as their relationship with clinicopathological features and prognosis. Results Tissue microarray with peritumoral and intratumoral tissue samples of 120 HCCs after hepatectomy was analysed for peritumoral expression of proliferating cell nuclear antigen for PI-DR. Peritumoral and intratumoral expression status of HPC markers including EpCAM, OV6, CD133 and c-kit were also examined by immunohistochemistry. TMA analysis of HCCs revealed that peritumoral PI-DR strongly correlated with the degree of inflammation and fibrosis. The peritumoral PI-DR positively correlated with peritumoral HPC markers EpCAM, OV6, CD133 and c-kit expression. Moreover, there were highly significant correlations between peritumoral PI-DR and intratumoral HPC markers EpCAM, OV6, CD133 and c-kit expression. Further, multivariate analysis showed that peritumoral PI-DR was the independent prognostic factor for overall survival (HR; 3.316, P < 0.001), and peritumoral PI-DR had a better power to predict disease-free survival (HR; 2.618, P < 0.001). Conclusions Peritumoral PI-DR, as a valid surrogate for peritumoral and intratumoral expression of HPC markers, could be served as a potential prognostic marker for recurrence and survival in HCC after hepatectomy.

Abstract
AIM: To investigate if loss of epithelial cell adhesion molecule (EpCAM) is associated with microinvasion in hepatocellular carcinomas (HCCs) in the presence of chronic hepatitis B.
METHODS: The expression of EpCAM, cytokeratin 7 (CK7) and CK19 in 112 hepatic nodules was studied, including 20 HCCs with nodules ≤ 3 cm, 26 HCCs with nodules > 3 cm, 20 high-grade dysplastic nodules, 26 cirrhotic, large regenerative nodules and 20 cases of cirrhosis.
RESULTS: Membranes of ductular reaction (DR) hepatobiliary cells, interlobular bile duct and some hepatic cells were positive for EpCAM expression. Active expression of DR/EpCAM was observed in the majority of noninvasive nodules (50/66, 75.76%); however, expression was absent in the major area of invasion in HCCs (42/46, 91.30%). DR/EpCAM loss in HCCs ≤ 3 cm was higher than in high-grade dysplastic nodules (HGDNs) (P < 0.05), cirrhotic, large regenerative nodules and cirrhosis (P < 0.01). Furthermore, patients (20 HCCs ≤ 3 cm, 26 HCCs > 3 cm, 20 HGDNs) with DR/EpCAM expression had a higher overall survival rate (P < 0.01) and lower early recurrence rate (P < 0.01). DR/EpCAM expression showed a close relationship with DR/CK7 and DR/CK19 expression (P < 0.01). The area under the receiver operating characteristic (ROC) curve of DR/EpCAM was similar to that of DR/CK7 and DR/CK19 (P > 0.05). The diagnostic specificity and diagnostic accuracy were both increased when DR/EpCAM, DR/CK7 and DR/CK19 were combined (P < 0.01).
CONCLUSION: DR/EpCAM loss may be a useful marker for determining microinvasion in HCCs ≤ 3 cm, but also for predicting prognosis.

Abstract
UNLABELLED Hepatic progenitor cells (HPC) play important roles in both liver regeneration and carcinogenesis. Combined hepatocellular-cholangiocarcinoma (CHC), a malignant primary liver tumor with poor prognosis, is thought to be of HPC origin. However, the prognostic significance of this etiology is not well defined. Therefore, we retrospectively investigated the relationship of HPC-related pathological features and long-term outcome in patients with CHC in our department. In a cohort of 80 patients identified between 1997 and 2003, including 70 patients who underwent resection with curative intent, overall survival (OS) and disease-free survival (DFS) were correlated with the proliferative activity of nontumor ductular reaction (DR) and the expression levels of HPC and biliary markers including α-fetoprotein (AFP), keratin 7 (K7), keratin 19 (K19), oval cell (OV)-6, epithelial cell adhesion molecule (EpCAM), and c-Kit in both tumor and nontumor liver. We found that nontumor ductular reactions (DRs), specifically the proliferating cell nuclear antigen (PCNA) labeling index of the ductular reaction (PI-DR), a surrogate for transit-amplifying compartments, was an independent prognostic factor for both OS and DFS. By contrast, intratumoral expression of only one marker, absence of AFP, was associated with OS. PI-DR was also independently associated with synchronous "multicentric occurrence" in hepatocellular carcinoma components, a feature of CHC that may predispose to metachronous multifocal tumorigenesis. CONCLUSION Proliferative ductular reaction related to HPC activation is associated with recurrence of CHC. Background HPC activation is strongly associated with multifocal occurrence and related tumor recurrence, highlighting the critical role of background liver disease, a "field effect," in the recurrence of CHC.

Abstract
PURPOSE OF REVIEW Keratins are a subgroup of intermediate filaments expressed in the epithelia. Keratins emerged as important tissue-protecting genes and keratin variants cause/predispose to development of more than 50 human disorders. Our review focuses on the importance of keratins in context of liver disease. RECENT FINDINGS K8/K18 variants are found in approximately 4% of white population and predispose to development and adverse outcome of multiple liver diseases. K8/K18 are major constituents of Mallory-Denk bodies, that is inclusions found in alcoholic and nonalcoholic steatohepatitis (NASH) and dysregulated keratin expression, K8 hyperphosphorylation, misfolding and crosslinking via transglutaminase 2 facilitate aggregate formation. Necrosis-generated and apoptosis-generated keratin serum fragments are emerging as important noninvasive markers of multiple liver diseases, particularly NASH. Keratins are established markers of tumor origin and in hepatocellular carcinoma, K19 expression is associated with poor prognosis. SUMMARY Keratins are established tumor markers and are widely used as noninvasive markers of liver injury. In addition, the data that have become available in recent years have greatly advanced our understanding of keratins as modifiers of liver disease development.

Abstract
Cirrhotic nodules containing hepatocytes are surrounded by perinodular stroma, that consists of an expanded fibrous matrix and epithelial cells with ductular phenotype, the "ductular-reaction". Stromal invasion is a key histopathologic feature used to differentiate premalignant dysplastic nodules from malignant hepatocellular carcinoma (HCC). K19 immunoreactivity in the stromal compartment in cirrhotic explants was examined. Quantitative differences were manifested in three distinct histologically identifiable patterns: "complex" around cirrhotic nodules, "attenuated" around dysplastic nodules, and "absent" around HCC. These findings suggest marked alterations in cellular identity as an underlying mechanism for the reproducible extralesional K19 pattern that parallels progressive stages of intranodular hepatocarcinogenesis. Paracrine signalling is proposed as a link that emphasizes the importance of the epithelial-stromal compartment in malignant progression of HCC in cirrhosis.
