myoepitheliomas are benign tumors which account for less than 1% of all salivary gland tumors. in this article, we report the clinical, pathologic, and immunohistochemical features of plasmacytoid myoepithelioma of the hard palate in a 73-year-old man having a painless hard palate mass with progressive growth for one month who was admitted in alzahra hospital of isfahan university of medical sc...

The present study aimed to assess the diagnostic/prognostic value of various clinical tumor markers, including carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cytokeratin 19 (CYFRA21-1), α-fetoprotein (AFP), carbohydrate antigen-125 (CA-125), carbohydrate antigen-19.9 (CA-19.9) and ferritin, individually or in combination. The electro-chemiluminescence immunization method was per...

background and objective: in this study, we explored expression rate, some biomarkers affecting the prognosis of the breast carcinoma, and the relationship between these markers and clinicopathologic features of the disease as well as the relationship between each of these markers through a tissue array technique. materials and methods: this study was an observational and cross-sectional study....

The ease and non-invasive nature of the procedure for drawing blood has made it possible to measure circulating tumor markers for cancer screening, diagnosis, follow-up and early detection of recurrence. Even though a tumor-specific marker has not yet been found, the specificity and sensitivity of currently used tumor markers have improved over the last several decades as they have progressed f...

abstract inflammatory pseudotumour describes as a wide range of neoplastic and reactive lesions. one of the rare presentations of these tumors is found in the salpinx. this case report characterizes a thirty six year old woman with a history of left sided abdominal pain for a few months. further examinations revealed that she had a complex cyst in her left salpinx. the patient had normal levels...

abstract background and aim: survivin is a new member of inhibitor of apoptosis protein family (iap) that plays an important role in the regulation of cell cycle and inhibition of apoptosis. distinct expression of this gene in tumoral cells versus normal cells introduces it as the fourth major transcriptome in cancers. thyroid carcinoma is the most common endocrine malignancy. considering the h...

BACKGROUND The purpose of this study is to investigate whether ordinary hepatocellular carcinomas (HCCs) show positivity of stem/progenitor cell markers and cholangiocyte markers during the process of tumor progression. METHODS Ninety-four HCC lesions no larger than 8 cm from 94 patients were immuno-histochemically studied using two hepatocyte markers (Hep par 1 and α-fetoprotein), five chola...

BACKGROUND Tumor markers (TMs) and D-Dimer are both hallmarks of severity and prognosis of lung cancer. Tumor markers could be related to pulmonary embolism (PE) in lung cancer. RESULTS The number of abnormal tumor markers of lung cancer patients with pulmonary embolism (3.9 ± 1.1vs1.6 ± 0.6,P 0.005) was more than that in patients without pulmonary embolism. TMs panel (P trend < 0.001), CEA (...

In this paper we describe the use of tumor marker estimation models in the prediction of tumor diagnoses. In previous work we have identified classification models for tumor markers that can be used for estimating tumor marker values on the basis of standard blood parameters. These virtual tumor markers are now used in combination with standard blood parameters for learning classifiers that are...
