While Ki-67 index is crucial for the diagnosis and grading and for prognostic and predictive purposes in digestive neuroendocrine tumors (NET), it does not play the same established role in lung NET. In fact, gastroenteropancreatic NE neoplasms are classified into two groups of NET and NE ...
摘要: Optimal histopathological analysis of biopsies from metastases of neuroendocrine tumor (NET) of the lung requires more than morphology only. Additional parameters such as Ki-67 labeling index are requ关键词:KI-67 antigen Immunohistochemistry Lung Neuroendocrine Tumors Typical Atypical Carcinoid Large...
Ki-67 is a nuclear protein associated with proliferation of tumor cells known as a prognostic factor for breast cancer.1-3In estrogen receptor (ER)–positiveERBB2(formerlyHER2/neu)–negative (ER+/ERBB2−) breast cancer, a higher Ki-67 index is associated with a more aggressive tumor and ...
The study measured intratumoral Ki-67 index heterogeneity, concordance rates of PNET grading by EUS- FNA with grade of the resected tumor, optimal method of measuring the Ki-67 index in EUS- FNA specimens, and survival analysis based on EUS-FNA specimen grading. Results: Intratumoral dispersion...
The prognostic value of histopathological grading and the growth pattern of small intestinal neuroendocrine tumors (SI-NET) is unclear. In particular, the cutoff level between grades G1 and G2 at Ki-67 index above 2% is an open issue, and both lower and higher cutoffs have been proposed. ...
Ki-67 labeling index (LI) is an important indicator of tumor cell proliferation in glioma, which can only be obtained by postoperative biopsy at present. This study aimed to explore the correlation between Ki-67 LI and apparent diffusion coefficient (ADC) parameters and to predict the level of...
Ki-67 index of tumor cells correlated with sex, stage of the process, size of tumor formation and prognosis, but did not correlated with age, invasion into the capsule and metastasis to the lymph nodes. Depending on the variants of Hsp70 and Ki-67 co-expression, three molecular types of ...

Ki-67 is a nuclear protein involved in cell proliferation regulation, and its expression has been widely used as an index to evaluate the proliferative activity of lymphoma. However, its prognostic value for lymphoma is still contradictory and inconclusi
