Effect of embolisation of meningioma on Ki-67 proliferation index.
The proliferation indices (PIs) were determined in 33 meningiomas using two monoclonal antibodies to the Ki-67 antigen (Ki-67 and MIB1). PIs obtained using Ki-67 on frozen material were intermediate between the lowest and highest MIB1 PIs determined in paraffin wax sections. Preoperative embolisation did not influence Ki67 PI, but four of the 15 embolised tumours showed substantially increased ...
متن کاملHistopathological parameters with Ki-67 and bcl-2 in the prognosis of meningiomas according to WHO 2000 classification.
AIMS AND BACKGROUND Meningiomas are classified following the WHO system of 2000 into three grades, benign (grade I), atypical (grade II), and anaplastic (grade III). We investigated the relation between tumor grade and Ki-67 and bcl-2. METHODS In the present study, 246 cases of meningioma were reclassified according to the WHO 2000 system. The relationship between tumor grade and morphologica...
متن کاملPrognostic relevance of the Ki-67 proliferation index in patients with mantle cell lymphoma
BACKGROUND A high Ki-67 proliferation index (PI) in neoplastic cells is associated with poor survival in mantle cell lymphoma (MCL). We aimed to determine the cut-off values for the Ki-67 PI as a prognostic factor in MCL according to bone marrow findings. METHODS Immunohistochemical (IHC) staining for Ki-67 was performed on formalin-fixed paraffin-embedded biopsy tissues from 56 patients with...
متن کاملcorrelation of adc map with the ki-67 index in glial tumor prognosis in patients of stereotaxic ward
background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...
متن کاملThe role of Ki-67 in the proliferation and prognosis of breast cancer molecular classification subtypes
The Ki-67 antigen was identified in the early steps of polymerase I-dependent ribosomal RNA synthesis. Although it seems that this protein has an important function in cell division, its exact role is still unclear and there is little published work on its overall function. The aim of the present study was to evaluate the contribution of the level of Ki-67 with respect to tumor recurrence in mo...
