Repression Of E-Cadherin By The Polycomb Group Protein Ezh2 In Pancreatic Cancer, A. D. Toll, A. Dasgupta, M. Potoczek, C. G. Kleer, J. R. Brody, A. K. Witkiewicz

Our study suggest that E-cadherin downregulation may lead to EZH20-mediated invasion and metastasis. While strong diffuse EZH2 expression is seen in PDA, overexpression may be present in IPMN.

Identification Of Gastrointestinal Contamination In Pancreatic Fna, A. D. Toll, M. Bibbo

In contrast to previous work, our preliminary results indicate B72.3 expression cannot be reliably used to identify GIC. A lack of CEA expression, however, may be used to identify both gastric and duodenal contamination. This represents an important diagnostic aid in the evaluation of suspected low-grade mucinous lesions.
Presence Of Endometrial Adenocarcinoma In Situ In Complex Atypical Endometrial Hyperplasia Is Associated With Increased Incidence Of Endometrial Carcinoma In Subsequent Hysterectomy., Khush Mittal, Matjaz Sebenik, Cybil Irwin, Zhijije Yan, Dorota Popiolek, John Curtin, Juan Palazzo

The distinction of complex atypical endometrial hyperplasia from endometrial adenocarcinoma is often problematic. Foci of back-to-back arrangement of glands or foci of cribriform arrangement of glands smaller than 2.1 mm in diameter are considered insufficient for the diagnosis of endometrial adenocarcinoma by some authors, and sufficient to be diagnosed as endometrial adenocarcinoma by other authors. We refer to these foci as endometrial adenocarcinoma in situ. In this study, we evaluated findings in subsequent hysterectomy in complex atypical endometrial hyperplasia patients with and without adenocarcinoma in situ. Follow-up findings, including the presence or absence of endometrial adenocarcinoma in the hysterectomy specimen, …
Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein
Nipple Aspirate Cytology And Pathologic Parameters Predict Residual Cancer And Nodal Involvement After Excisional Breast Biopsy., E R Sauter, H Ehya, A Mammen, G Klein
Department of Surgery Faculty Papers
We previously demonstrated that abnormal nipple aspirate fluid (NAF) cytology predicted residual breast cancer (RC) and tumour size after excisional biopsy (EB), although normal NAF cytology did not exclude RC. Tumour size correlates with the risk of lymph node (LN) metastases. LN metastases provide prognostic information allowing medical and radiation oncologists to determine the need for adjuvant therapy. We hypothesized that pathologic factors known after EB, combined with NAF cytology, would predict with a high degree of accuracy the presence of RC and LN spread. NAF cytology and pathologic parameters: tumour distance from biopsy margins, multifocal and multicentric disease, sub-type …
The Role Of Calcium Ions In Toxic Cell Injury., John L. Farber
The Role Of Calcium Ions In Toxic Cell Injury., John L. Farber
Department of Pathology, Anatomy, and Cell Biology Faculty Papers
Calcium ions have been increasingly implicated as a mediator of the mechanisms generating lethal cell injury under a variety of pathologic circumstances. An overview of the various roles suggested for such alterations in cellular calcium homeostasis is presented. The central role of plasma membrane damage in the genesis of irreversible cell injury is used to divide the postulated roles for calcium ions into two major mechanisms. On the one hand, calcium ions have been proposed as mediators of the functional consequences of plasma membrane injury. An influx of extracellular calcium ions across a damaged permeability barrier and down a steep …
