BACKGROUND The presence or absence of metastatic disease in cervical lymph nodes is the single most important determinant of therapy and prognosis for patients with head and neck squamous cell carcinoma (HNSCC). However, histologic examination fails to detect metastatic disease in a subset of neck dissection specimens. The accuracy of neck staging may be improved by the use of molecular techniq...
OBJECTIVES Biological markers that predict the development of invasive breast cancer are needed to improve personalized therapy for patients diagnosed with ductal carcinoma in situ. We investigated the role of basal cytokeratin 5/6 in the risk of invasion in breast ductal carcinoma in situ. METHODS We constructed tissue microarrays using 236 ductal carcinoma in situ samples: 90 pure samples (...
of the pancreas is extremely rare [1]; only three cases have been reported in the literature [2–4]. A61-year-oldmanpresentedwith abdominal pain. Laboratory blood testing revealed hyperamylasemia (626 IU/L). Tumor marker concentrations were within normal ranges. Upper gastrointestinal endoscopy showed no significant changes, as did CT including the pancreas. Pancreatitis was suspected and the pa...

Mucinous cystic neoplasms (MCN) with malignant sarcomatous stroma are rare aggressive tumors and there are few recorded cases. We report a case of MCN that had adenocarcinoma in situ and invasive adenocarcinoma with foci of sarcomatous stroma in a 40-year-old woman. Clear transition from adenocarcinoma areas into sarcomatoid foci was noted. The stromal component showed immunoreactivity for CK7 ...
BACKGROUND/AIM Usual histopatological diagnosis of intrauterine pregnancy is made by demonstration of chorionic villi, but in the curettage tissue from intrauterine miscarriage they may not be present in all cases. The use of monoclonal antibody against cytokeratin as a sensitive and reliable marker for the morphologic discrimination between invasive trophoblastic (IT) cells and decidual cells ...
While several prognostic factors have been identified in breast carcinoma, the clinical outcome remains hard to predict for individual patients. Better predictive markers are needed to help guide difficult treatment decisions. In a previous study of 78 breast carcinoma specimens, we noted an association between poor clinical outcome and the expression of cytokeratin 17 and/or cytokeratin 5 mRNA...
