Somatostatin analogues (SSAs) have shown limited and variable antiproliferative effects in neuroendocrine tumours (NETs). Whether tumour control by SSAs depends on grading based on the 2010 WHO NET classification is still unclear. The aim of this study is to evaluate the efficacy of long-acting SSAs in NETs according to Ki67 index. An observational Italian multicentre study was designed to coll...

Sinonasal-inverted papilloma is a benign tumour with a high rate of recurrence, but possible malignant transformation. Therefore, investigation of predisposition to malignant transformation of sinonasal-inverted papilloma gives clinicians the opportunity for adequate treatment. Topoisomerase II-alpha (topoII-alpha) and Ki67 are markers of cell proliferation in both normal and neoplastic tissues...

Methods. To further evaluate the relationship between ROG and melanoma proliferation, we assessed the correlation of ROG with Ki67, a commonly used marker of cell cycle progression, and phosphorylated-histone-H3 (PH3), a sensitive marker of mitosis. The methods of assessing Ki67 and PH3 have been described elsewhere. In brief, recuts of a representative section within the primary melanoma were ...
The grading system for pancreatic neuroendocrine tumors (PanNETs) adopted in 2010 by the World Health Organization (WHO) mandates the use of both mitotic rate and Ki67/MIB-1 index in defining the proliferative rate and assigning the grade. In cases when these measures are not concordant for grade, it is recommended to assign the higher grade, but specific data justifying this approach do not ex...
BACKGROUND Meningioma is among the most common slow growing central nervous neoplasms, which recurs locally despite the benign histologic features. The aim of this study was to evaluate osteopontin and ki67 expressions in different histologic grades of meningioma in a group of Iranian people. METHODS In this cross-sectional study, first, the paraffin blocks with the definite pathological diag...
Previous studies have found that 1,25-dihydroxyvitamin D3 [1,25(OH)2D3 or VD3] exerts many biological effects, including the inhibition of cell proliferation and induction of apoptosis, but its mechanism of action remains unclear. The goal of our investigation was to explore the effects of 1,25(OH)2D3 on the proliferation of cultured human mesangial cells and their expression of Ki67 in vitro, ...
OBJECTIVES Oral leukoplakia is a precancerous lesion of the oral mucosa. The upregulation of Ki67 and cyclooxygenase-2 has been reported in both dysplastic and non-dysplastic tissues. The aim of this clinicopathological study was to investigate the prognostic value of Ki67 and cyclooxygenase-2 expression for oral leukoplakia. MATERIAL AND METHODS A total of 50 samples were investigated and th...
