Ultrarapid Ki-67 immunostaining in frozen section interpretation of gliomas.

BACKGROUND Astrocytic tumours, the most common gliomas, are often classified intraoperatively using standard morphological staining. The final diagnosis and grading of gliomas on paraffin wax sections is often assisted by Ki-67 immunohistochemistry, but standard immunostaining protocols take too long to be used intraoperatively. AIMS To investigate a new rapid Ki-67 immunohistochemical test f...

Ki-67/MIB-1 immunostaining in a cohort of human gliomas.

Histopathological malignancy grading of human gliomas is limited by subjective interpretation of the morphological criteria. Assessment of mitotic activity is a cornerstone of grading these tumours, but mitotic figures can be hard to identify in haematoxylin-eosin stained sections. Thus, determining proliferative activity by means of Ki-67/MIB-1 immunostaining has become a useful supplement. Ho...

Utility of Ki-67 (MIB-1) Immunostaining in Cervical Biopsies

Nearly every pathologist that practices in a community hospital setting struggles with the accurate and reproducible identification of HPV effect and dysplasia in the female genital tract, and recognizes the fact that in certain situations these conditions can be very difficult to distinguish from reactive changes. Last month in the ProPath "Focus on Immunohistochemistry", we reviewed the poten...

Technical report Protocol for ultrarapid immunostaining of frozen sections

Rapid immunostaining of frozen sections within a tolerable time span would be very helpful for intraoperative diagnosis. A protocol was therefore established using the enhanced polymer one-step staining (EPOS) system (Dako) with antibodies against leucocyte common antigen (LCA), cytokeratin (CK), and anti-melanoma (MEL). Best results with reliable and specific immunostaining and a labelling int...

P16/Ki-67 Immunostaining is Useful in Stratification of Atypical Metaplastic Epithelium of the Cervix

Cervical metaplastic squamous epithelium exhibiting atypia insufficient for a diagnosis of cervical intraepithelial neoplasia (CIN) is usually reported as "atypical squamous metaplasia" (ASM). Stratification impacts treatment since the differential is often between reactive and high grade CIN (CIN II, III). Diagnosis with H&E is associated with low intra/interobserver concurrence. P16/Ki-67 imm...
