Is Ki-67 index overexpression in IDH wild type glioblastoma a predictor of shorter Progression Free survival? A clinical and Molecular analytic investigation.

Clinical neurology and neurosurgery (Dutch-Flemish ed. Print), 2020
BACKGROUND Ki-67 proliferation index is widely used for differentiating between high and low-grade gliomas, but differentiating between the same grade IV appears to be more problematic, and the point about its prognostic value for GBM patients remains ...

Joint Prediction of Breast Cancer Histological Grade and Ki-67 Expression Level Based on DCE-MRI and DWI Radiomics

IEEE journal of biomedical and health informatics, 2019
Objective: Histologic grade and Ki-67 proliferation status are important clinical indictors for breast cancer prognosis and treatment. The purpose of this study is to improve prediction accuracy of these clinical indicators based on tumor radiomic ...

Radiomic mapping model for prediction of Ki-67 expression in adrenocortical carcinoma.

Clinical Radiology, 2020
AIM To determine the value of contrast-enhanced computed tomography (CT)-derived radiomic features in the preoperative prediction of Ki-67 expression in adrenocortical carcinoma (ACC) and to detect significant associations between radiomic features and ...

Ki-67 Labeling Index in Breast Cancer

Tumori Journal, 1989
Measurements 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, 1990
Although 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.

Ki-67 is an indicator of progression of neuroendocrine tumors

Endocrine Pathology, 1994
No 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 ...

Immunohistochemical evaluation of PCNA and Ki-67 in ameloblastoma

Oral Oncology, 2001
Thirty-two ameloblastoma tissues were immunohistochemically studied using monoclonal anti-proliferating cell nuclear antigen (PCNA) and anti-Ki-67 antibodies. Positive cells were evaluated and analyzed in relation to the WHO classification, cytological pattern of the outer layer cell, clinical appearance, tumor location, radiographic appearance and ...

Tumour angiogenesis and Ki‐67 expression in phaeochromocytoma

BJU International, 2001
Objective To determine the expression of CD34 (to evaluate vascularity) and Ki‐67 (as a proliferative index) in a variety of phaeochromocytomas and thus assess the utility of these markers as possible predictors of malignancy. Patients and methods

Objective: to study peculiarities of the course of breast cancer (BC) with Ki-67 overexpression depending on the area occupied by the tumor stroma. Object and methods: the study included 220 patients with BC (T1N0M0 ??? 19, T2N0M0, T1N1M0 ??? 90, T2N1M0, T3N0M0 ??? 98, T4N0M0 ??? 13).

Ki-67 index in metastatic prostate cancer.

European urology, 2001
Prostate cancer in bone is generally thought to progress more rapidly than in its primary site, a supposition that is supported by studies of prostate-specific antigen velocity. However, descriptions of proliferative rates in metastases have relied on inferred data from in vitro studies of cell lines derived from metastases.
