Is MIB 1 the same as Ki67?
In recent years, MIB-1 (a true equivalent of Ki-67) has been proven to be the best proliferation marker for routine use in formalin-fixed and paraffin-embedded tissue sections (4, 7, 24).
Why is it called ki-67?
In 1983, a monoclonal antibody, Ki67, was generated, that labeled the nuclei of proliferating non-neoplastic and neoplastic cells. The name Ki67 derived from the city of Kiel (Ki) where the antibody was produced in the university department of pathology and refers to the number of the original clone (67).
What is considered a high KI 67 score?
Understanding Your Ki-67 Results Less than 10% is considered low. 20% or higher is considered high.
What is P16 and Ki67?
P16 is of great significance for the screening of cervical cancer, but by itself may not be sufficient for diagnosis. Ki-67 is a nuclear antigen that can be detected in the non-G0 phase of the cell cycle, marking the process of cell proliferation (5).
How reliable is Ki67?
In the POETIC trial, for patients with high Ki-67 levels at baseline and after 2 weeks of NET, the 5-year absolute risk of recurrence was 21.5%. The risk was 8.4% for those with high baseline but low 2-week Ki-67 levels, and 4.3% for those with low levels at both time points.

What is Ki67 80%?
The patients with high grade disease who achieved complete remission or good partial remission and had a Ki67 index of less than 80 per cent were more likely to relapse than those with an index of greater than 80 per cent (p less than 0.04).
How accurate is Ki-67?
The mean Ki-67 values obtained by using the two methods differed (A: 21.32% and C: 16.07%). Ki-67 assessed by using method A with a cut-off of 10% was a predictive marker for OS, as the hazard ratio (>10% vs. <=10%) in patients with chemotherapy was 0.48 with a 95% confidence interval of [0.19–1.19].
What is Ki-67 10%?
In test results, you will see the Ki-67 findings expressed as a percentage. This is the percentage of the total sample that has active Ki-67 proteins. This is used to estimate how many cells are actively dividing, as follows:6. Less than 10% is considered low. 20% or higher is considered high.
What is considered a high Ki67 score?
What does p16 stain mean?
Clinical Information. p16 (INK4a/CDKN2A) is a cell cycle regulatory protein that is overexpressed in cervical dysplasia related to human papilloma virus (HPV) infection. Nuclear and cytoplasmic staining is seen in dysplastic squamous cervical epithelial cells infected with HPV, but not in normal cells.
