objective: gliomas are the most common primary brain tumors, and have been ranked as the fourth leading cause of cancer death. tumor mesenchymal-like stem cells (tmscs) contribute to the aggressive behavior of glial tumors by providing a favorable microenvironment for the malignant cells. the aims of our study were to identify differential proteome of tmscs derived from low vs. high grade gliom...

AIM To investigate the marital status and fertility in long-term survivors of high-grade osteosarcoma. PATIENTS AND METHODS We surveyed the marital rate (number of married persons/total number of persons) in 46 long-term survivors of osteosarcoma who were treated in our hospital between 1976 and 2002. In addition, we examined the fertility rate (number of persons having offspring/number of ma...

INTRODUCTION Current grading system in application by WHO/ISUP divides urothelial malignancies in low and high grade by morphologic criteria while strict segregation may become cumbersome in limited tissue specimens. As grading these carcinomas are of utmost prognostic significance after depth of invasion, therefore we evaluated the role of immunohistochemical expression of p53 and cytokeratin ...

BACKGROUND Mucoepidermoid tumors (METs) of the trachea and bronchi are rare. They derive from the minor salivary gland tissue of the proximal tracheobronchial tree, and their clinical behaviors are still controversial. Herein, we analyze 11 cases of MET to investigate its clinicopathological characteristics. METHODS The medical records and pathological examinations of patients diagnosed with ...

High-grade neuroendocrine carcinoma differs from usual neuroendocrine carcinoma, and its prognosis is dismal. In this case report, a case of high-grade neuroendocrine carcinoma that improved with bevacizumab plus modified FOLFOX6 as the fourth-line chemotherapy is presented. A 29-year-old male with a huge liver tumor was diagnosed with high-grade neuroendocrine carcinoma originating from the li...

Sarcomatoid squamous cell carcinomas are extremely rare, high grade, aggressive variant of penile cancers. Sarcomatoid carcinoma are biphasic neoplasms with a combination of both sarcomatoid components and carcinomatous elements. These neoplasms are very rare in the urogenital system. We report a 53-year-old male presented with an ulcerated lesion on the glans penis. The rarity of this case rei...

abstract   background: squamous cell carcinoma (scc) constitutes the main oral malignancy . parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as epidermal growth factor (egf) and laminin-5 are sought to estimate macroscopic and microscopic tumor status .   methods: we conducted a cross-sectional study collecting ...

background: certain marker studies have practical importance in the biology of prostate cancer. the purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas.   methods: the present study was performed on sampl...
