KI-67, A MARKER of cellular proliferation, has been studied extensively in pituitary neoplasia. It is of relevance to various clinicopathological parameters, including tumor subtype, size, invasiveness, and recurrence, as well as patient age and sex. Generally, pituitary tumors behaving aggressively have increased Ki-67 labeling indices.

To analyze the prognostic value of Ki-67 in oral cancer and its relationship with Ki-67 expression in precancerous epithelium.We studied 79 tumors from 65 patients. Immunohistochemistry study with Mib-1 monoclonal antibody was used to detect Ki-67 expression in tumor tissue and adjacent non-tumor tissue. The influence of different variables on survival

Ki-67 – new faces of an old player
Orvosi Hetilap, 2009Huszonöt évvel ezelőtt izolálták először a Ki-67 fehérjét, ami napjainkra az osztódó sejtek első számú hisztológiai markere lett. Ez a kivételes szerkezetű molekula olyan alapvető biológiai funkciókkal bír, amelyek nélkülözhetetlenek a normális sejtciklushoz.

Ki-67 is an indicator of progression of neuroendocrine tumors
Endocrine Pathology, 1994No current histological or cytological indices can distinguish reliably malignant from benign tumors in neuroendocrine tumors, including pheochromocytomas, pancreatic endocrine tumors, and carcinoid tumors. We investigated immunohistochemically the expression of Ki-67 in 52 neuroendocrine tumors, including 17 pheochromocytomas, 9 pancreatic endocrine ...

The Ki-67 protein: From the known and the unknown
Journal of Cellular Physiology, 2000The expression of the human Ki-67 protein is strictly associated with cell proliferation. During interphase, the antigen can be exclusively detected within the nucleus, whereas in mitosis most of the protein is relocated to the surface of the chromosomes.

Ki‐67 and p53 in T2 laryngeal cancer
The Laryngoscope, 1998AbstractObjective: To study the relationship between the proliferative capacity, represented by the immunohistochemical labeling index (LI) of proliferation marker Ki‐67, and the p53 status, as in theory an intact p53 cell cycle checkpoint system should result in a lower proliferative capacity.

Ki-67 immunostaining and prognosis in laryngeal cancer
Clinical Otolaryngology and Allied Sciences, 1998The expression of the antigen defined by the Ki-67 antibody in paraffin sections from 154 biopsies of laryngeal squamous cell carcinomas was examined. There was a significant difference in Ki-67 expression between the control group and the patients with cancer (P < 0.001). There was no significant difference in the Ki-67 score between the patients with

Ki-67 Labeling Index in Breast Cancer
Tumori Journal, 1989Measurements of cell cycle kinetics have been found to correlate with the clinical course of patients with breast cancer. However, the thymidine labeling index and more rapid methods like flow cytometry remain complicated and costly. We assessed cell proliferation of 67 breast carcinomas by an immunoperoxidase procedure using a monoclonal antibody, Ki-

Ki‐67 and grading of malignant fibrous histiocytomas
Cancer, 1990Although generally considered to be of high grade, malignant fibrous histiocytomas (MFH) show a range of histologic appearances and a diverse biologic behavior. More precise grading of this type of sarcoma is desirable. The rate of cell proliferation may reflect clinical behavior.

The role of Ki-67 in breast cancer.
South African journal of surgery. Suid-Afrikaanse tydskrif vir chirurgie, 2016The proliferative marker, Ki-67, is a human nuclear antigen, and forms an integral part of cell division in both normal and malignant tissue. Since the hallmark of cancer is uncontrolled and relentless cell proliferation, the Ki-67 proliferative index is increasingly used to assess and manage breast cancer. The value of Ki-67 as a prognostic indicator,
