Cholangiocarcinoma (CCA) develops through multistep carcinogenesis. During the past decades, 2 precursors have been proved to evolve to CCA. The 2 main precursor lesions of CCA are biliary intraepithelial neoplasia and intraductal papillary neoplasm of the bile duct. It is an interesting and relatively novel entity for the hepatobiliary surgeons, radiologists, oncologists, and pathologists. It worth being familiar with these 2 entities for better communication between pathologists, oncologists, ...[more]

Project description:CD155, an immunoglobulin-like adhesion molecule, plays an important role in carcinoma such as cells migration, proliferation, metastasis, and tumor immune. The upregulation of CD155 has been found in several human malignancies, but its expression in cholangiocarcinoma (CCA) still remains unclear. The aim of this study is to investigate CD155 expression and its correlations with clinicopathologic data, angiogenesis, and prognosis in the patients with CCA.CD155 expression was investigated in 20 paired CCA tissues and corresponding paracancerous tissues by Western blotting and quantitative real-time polymerase chain reaction assays at protein and mRNA levels. Besides, this study evaluated the correlation between the tumor CD155 expression and the level of both vascular endothelial growth factor and intratumoral microvessel density by immunohistochemistry in 90 cases of CCA. Moreover, the clinical and prognostic significance of CD155 in CCA was assessed by immunohistochemistry.The protein and mRNA levels of CD155 were higher in CCA tumor tissues compared with corresponding paracancerous tissues (P<0.05). Immunohistochemical staining showed that CD155 was located in the cytoplasm of carcinoma cells and overexpressed in 61.2% (55/90) CCA tissues. Obviously, CD155 expression level was significantly correlated with tumor histological grade (P=0.002), lymph node metastasis (P<0.001), and tumor-node-metastasis (P=0.03). Additionally, Spearman rank correlation test demonstrated that CD155 expression was positively associated with vascular endothelial growth factor (r=0.481, P<0.001) and microvessel density (r=0.442, P<0.001) in CCA tissues. More importantly, CCA patients with high CD155 expression had a markedly shorter overall survival (P<0.001) and disease-free survival (P<0.001) after surgical resection, and multivariate analysis showed that high CD155 expression was an independent poor prognostic predictor of overall survival and disease-free survival (P<0.001).Our results revealed that upregulated CD155 correlated with aggressive clinicopathologic characteristics, angiogenesis, and poor prognosis in CCA and may be a promising prognostic biomarker for the CCA patients.

Project description:PurposeThe current paradigm in the development of high-grade serous ovarian carcinoma (HGSC) proposes that the majority of HGSCs arise from precursor serous tubal intraepithelial carcinoma (STIC) lesions of the fallopian tube. Here we survey genome-wide methylation in HGSC precursor lesions to identify genomic regions that exhibit high-specificity differential hypermethylation for potential use as biomarkers for detecting STIC and HGSC at stages when curative intervention likely remains feasible.Experimental designWe first identified quality control criteria for performing reliable methylomic analysis of DNA-limited tubal precursor lesions with the Illumina Infinium MethylationEPIC array. We then used this platform to compare genome-wide methylation among 12 STICs with paired adjacent-normal epithelia, one p53 signature lesion and two samples of concurrent HGSC. The resulting methylomic data were analyzed by unsupervised hierarchical clustering and multidimensional analysis. Regions of high-confidence STIC-specific differential hypermethylation were identified using selective bioinformatic criteria and compared with published MethylationEPIC data from 23 HGSC tumors and 11 healthy fallopian tube mucosae.ResultsUnsupervised analysis showed that STICs largely clustered with HGSCs, but were clearly distinct from adjacent-normal fallopian tube epithelia. Forty-two genomic regions exhibited high-confidence STIC-specific differential hypermethylation, of which 17 (40.5%) directly overlapped with HGSC-specific differentially methylated regions. Methylation at these shared loci was able to completely distinguish STIC and HGSC samples from normal and adjacent-normal specimens.ConclusionsOur results suggest that most STICs are epigenetically similar to HGSCs and share regions of differential hypermethylation that warrant further evaluation for potential use as biomarkers for early detection of ovarian HGSC.See related commentary by Ishak and De Carvalho, p. 6083.

Project description:Pancreatic adenocarcinoma displays a variety of molecular changes that evolve exponentially with time and lead cancer cells not only to survive, but also to invade the surrounding tissues and metastasise to distant sites. These changes include: genetic alterations in oncogenes and cancer suppressor genes; changes in the cell cycle and pathways leading to apoptosis; and also changes in epithelial to mesenchymal transition. The most common alterations involve the epidermal growth factor receptor (EGFR) gene, the HER2 gene, and the K-ras gene. In particular, the loss of function of tumor-suppressor genes has been documented in this tumor, especially in CDKN2a, p53, DPC4 and BRCA2 genes. However, other molecular events involved in pancreatic adenocarcinoma pathogenesis contribute to its development and maintenance, specifically epigenetic events. In fact, key tumor suppressors that are well established to play a role in pancreatic adenocarcinoma may be altered through hypermethylation, and oncogenes can be upregulated secondary to permissive histone modifications. Indeed, factors involved in tumor invasiveness can be aberrantly expressed through dysregulated microRNAs. This review summarizes current knowledge of pancreatic carcinogenesis from its initiation within a normal cell until the time that it has disseminated to distant organs. In this scenario, highlighting these molecular alterations could provide new clinical tools for early diagnosis and new effective therapies for this malignancy.

Project description:BackgroundWe investigated the radiologic and clinical findings of radial scar and complex sclerosing lesions, and evaluated the rate of pathologic upgrade and predicting factors.MethodsFrom review of our institution's database from January 2006 to December 2012, we enrolled 82 radial scars/complex sclerosing lesions in 80 women; 51 by ultrasound guided core needle biopsy, 1 by mammography-guided stereotactic biopsy, and 38 by surgical excision. The initial biopsy pathology revealed that 53 lesions were without high risk lesions and 29 were with high risk lesions. Radiologic, clinical and pathological results were analyzed statistically and upgrade rates were calculated.ResultsOf the 82 lesions, 64 (78.0%) were surgically excised. After surgical excision, two were upgraded to DCIS and two were upgraded to lesions with high risk lesions. The rate of radial scar with high risk lesions was significantly higher in the surgical excision group (11.1% vs. 42.2%, p?=?0.015), which also demonstrated larger lesion size (10.7?±?6.5 vs. 7.1?±?2.6 mm, p?=?0.001). The diagnoses with high risk lesions on final pathological results showed older age (52.9?±?6.0 years vs. 48.4?±?6.7 years, p?=?0.018).ConclusionsRadial scars with and without high risk lesions showed no statistically significant differences in imaging, and gave relatively low cancer upgrade rates.

Project description:BackgroundMost colorectal cancers (CRC) arise from precursor lesions. This study aimed to characterize the mutation profile of colorectal cancer precursor lesions in a Brazilian population.MethodsIn total, 90 formalin-fixed paraffin-embedded colorectal precursor lesions, including 67 adenomas, 7 sessile serrated lesions, and 16 hyperplastic polyps, were analyzed by next-generation sequencing using a panel of 50 oncogenes and tumor suppressor genes. The genetic ancestry of the patients was estimated.ResultsSomatic driver mutations were identified in 66.7% of cases, including alterations in APC (32.2%), TP53 (20.0%), KRAS (18.9%), BRAF (13.3%) and EGFR (7.8%). Adenomas displayed a higher number of mutations, mainly in APC, compared to serrated polyps (73.1% vs. 47.8%, p = 0.026). Advanced adenomas had a significantly higher frequency of mutation in KRAS and a high overall mutation rate than early adenomas (92.9% vs. 59%, p = 0.006). A high degree of ancestry admixture was observed in the population studied, with a predominance of European components (mean of 73%) followed by African (mean of 11.3%). No association between genetic ancestry and type of lesions was found. The mutation profile of Brazilian colorectal precursor lesions exhibits alteration in APC, KRAS, TP53, and BRAF at different frequencies according to lesion type.ConclusionsThese results bestow the knowledge of CRC's biologic history and support the potential of these biomarkers for precursor lesions detection in CRC screening of the Brazilian population.

Project description:BackgroundWith less than a 5% survival rate pancreatic adenocarcinoma (PDAC) is almost uniformly lethal. In order to make a significant impact on survival of patients with this malignancy, it is necessary to diagnose the disease early, when curative surgery is still possible. Detailed knowledge of the natural history of the disease and molecular events leading to its progression is therefore critical.Methods and findingsWe have analysed the precursor lesions, PanINs, from prophylactic pancreatectomy specimens of patients from four different kindreds with high risk of familial pancreatic cancer who were treated for histologically proven PanIN-2/3. Thus, the material was procured before pancreatic cancer has developed, rather than from PanINs in a tissue field that already contains cancer. Genome-wide transcriptional profiling using such unique specimens was performed. Bulk frozen sections displaying the most extensive but not microdissected PanIN-2/3 lesions were used in order to obtain the holistic view of both the precursor lesions and their microenvironment. A panel of 76 commonly dysregulated genes that underlie neoplastic progression from normal pancreas to PanINs and PDAC were identified. In addition to shared genes some differences between the PanINs of individual families as well as between the PanINs and PDACs were also seen. This was particularly pronounced in the stromal and immune responses.ConclusionsOur comprehensive analysis of precursor lesions without the invasive component provides the definitive molecular proof that PanIN lesions beget cancer from a molecular standpoint. We demonstrate the need for accumulation of transcriptomic changes during the progression of PanIN to PDAC, both in the epithelium and in the surrounding stroma. An identified 76-gene signature of PDAC progression presents a rich candidate pool for the development of early diagnostic and/or surveillance markers as well as potential novel preventive/therapeutic targets for both familial and sporadic pancreatic adenocarcinoma.

Project description:Oral lichen planus (OLP) and oral lichenoid lesions (OLL) are clinically and histologically similar lesions but their treatment planning and prognosis are different. The review of the literature indicates numerous criteria to distinguish these two lesions; however there is a lot of inconsistency. Thus, the aim of this study was to determine the correlation of histopathology and clinical OLP and OLL diagnosis and to clarify which histopathologic criteria could best distinguish these two diagnoses. A retrospective study showed that clinically diagnosed 92 OLPs and 14 OLLs have been confirmed histopathologically in 52.2% and 42.9% of cases, respectively. In addition, histopathology showed statistically significant more eosinophils (P<0.0005), plasma cells (P<0.0005), and granulocytes (P<0.05) in OLL than OLP. To establish histopathological diagnosis of OLP and OLL it should be mandatory to define the type of cells in mononuclear infiltrate, which can be associated more accurately with clinical feature and patient history. Therefore, currently accepted diagnostic criteria for OLP and OLL should be modified and validated on a larger number of patients taking into account particular distinguishing histopathological features.

Project description:PURPOSE: Disease-specific survival (DSS) for proximal bile duct cancer has been reported to be worse than for carcinoma of the distal duct. METHODS: Review of two prospectively maintained databases identified 204 patients who underwent resection for extrahepatic cholangiocarcinoma (proximal: n=106, 52%; distal: n=98, 48%) between December 1987 and December 2005. Patient, tumor, and treatment-related variables were reviewed. Analyses were performed to compare tumor presentation, treatment, and DSS between patients with resected proximal and distal lesions. RESULTS: Median follow-up for the 204 resected patients was 24 months (range 1-165 months) and 56 months for those alive at last follow-up. Combined liver/bile duct resection was performed in 82% of patients with proximal lesions, and pancreaticoduodenectomy was performed in 92% of patients with distal lesions. Patients experienced similar postoperative length of stay (median: proximal, 13 days vs. distal, 13 days; p=0.64) and operative mortality (30-day: proximal, 4% vs. distal, 3%; p=1.0, Fishers). Margin positive rates were similar (proximal, 23% vs. distal, 15%; p=0.20). Estimated five-year DSS for all patients was 35%. Tumor location (proximal vs. distal) was not associated with five-year estimated DSS (proximal, 29% vs. distal, 43%; p=0.44). Factors associated with five-year DSS included stage at presentation (node negative, 42% vs. node positive, 22%; p=<0.001), differentiation (papillary, 53% vs. non-papillary, 27%; p=0.01), and margin status (margin negative 42% vs. margin positive 27%; p<0.001). CONCLUSIONS: These results suggest that patients with resected proximal and distal cholangiocarcinoma will experience similar operative outcomes and DSS.
