OBJECTIVE Colorectal cancer is one of the major contributors to cancer death worldwide. Lack of reliable colorectal cancer markers has hampered the management of these cancer patients. Our main purpose was to study the correlation between histopathological variables of colorectal adenocarcinomas and identify histopathological markers that are of prognostic value in patients with colorectal canc...

BACKGROUND Giant cell tumor is an infrequent and unpredictable bony lesion. Although numerous attempts have been made to predict the behaviour of GCT, there are no definite biological or histological parameters to determine the prognosis or aggressiveness of this lesion MATERIALS AND METHODS We analyzed Ki 67 immuno-histochemistry of 31 consecutive cases staged III giant cell tumor to determi...

The study aimed at examining a relationship between expression of Ki-67 antigen and minichromosome maintenance 2 protein (MCM-2) and a grade of histological malignancy G in ductal breast cancers. The function of widely used marker of proliferation Ki-67 is still not clear. In contrast, the MCM-2 protein is well known to play an important role in controlling the cell cycle. Both proteins represe...

Adenoid cystic carcinoma (AdCC) and polymorphous low-grade adenocarcinoma (PLGA) have several common histological and clinicopathological features that may create diagnostic difficulties. In this study, 10 AdCCs, 8 PLGAs, and 5 normal minor salivary glands as a control group were selected. Sections prepared from each tumor were stained using the streptavidin-biotin system for seven marker antig...

BACKGROUND Proliferative activity has been shown to be of prognostic significance for several malignancies. Ki-67, a cell cycle associated antigen, is regarded as a promising proliferation marker. Very few results on the proliferative activity of head and neck cancer and their potential prognostic value are available. MATERIALS AND METHODS The proliferative activity of 104 squamous cell carci...

Background : Basal cell carcinoma (BCC) is the most commonest malignant tumor of skin especially fair-skinned individuals makes up roughly 70–80% all tumors. In certainty, this malignancy had a variety many sub-types, through distinct histo-morphological appearance and biological function. Unlike other tumors, usually has an affirmative clinical course, developing slowly just locally. Antibodie...
