PURPOSE To investigate the distribution of Ki67+ cells in breast cancer in relation to clinical-pathological parameters and prognosis. MATERIALS AND METHODS Ki67 expression status was detected in 1,086 breast cancer specimens using immunohistochemistry staining and examining the relationship between the Ki67+ cells' location. Subsequently, clinical-pathological parameters and prognosis were d...
Background: Ewing sarcoma family tumors (ESFTs) are among the most malignant tumors in children and young adults. ESFTs include Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumors (pPNETs). As there seemed to be few studies on the molecular biology of ESFTs, we investigated the frequency of CD99, Ki67, p53 and Fli- 1 protein expression in 15 Iranian patients with ESFTs. In addi...
AIM To evaluate the utility of Ki67 as a prognostic marker in a series of patients with node-negative breast cancer untreated with adjuvant systemic therapy. METHODS The cohort consisted of 203 cases treated with breast conserving surgery and radiation only; median follow-up was 183 months (range 156-277 months). An immunohistochemical panel of oestrogen receptor (ER), progesterone receptor (...
OBJECTIVE We investigated the expression of early and late phase BK virus (BKV) proteins and their interactions with host cell proteins in renal allografts, with ongoing polyomavirus associated nephropathy (PVAN), and correlated this with the nuclear and cell morphology. METHODS Frozen sections from three patients with renal allografts (two biopsies, one explant) with PVAN were analysed by in...

زمینه و هدف : سرطان پستان یکی از مهمترین تومورهای بدخیم و دومین سرطان شایع در زنان است. مجموعهای از عوامل محیطی و آسیبهای ژنتیکی در ایجاد این سرطان نقش دارند. ژن Ki67 یک پروتوانکوژن است که در روند تکثیر سلولی فعال است. بررسی پروتئین Ki67 از نظر پاسخ به شیمیدرمانی و پیشآگهی بیماری اهمیت دارد. این مطالعه به منظور بیان ژن Ki67در بیماران مبتلا به سرطان پستان به روش ایمونوهیستوشیمی انجام شد. ...
INTRODUCTION Breast cancer aggressiveness can be correlated with proliferation status of tumor cells, which can be ascertained with tumor grade and Ki67 indexing. However due to lack of reproducibility, the ASCO do not recommend routine use of Ki67 in determining prognosis in newly diagnosed breast cancers. We therefore aimed to determine associations of the Ki67 index with other prognostic mar...
BACKGROUND In the neoadjuvant setting, changes in the proliferation marker Ki67 are associated with primary endocrine treatment efficacy, but its value as a predictor of response to chemotherapy is still controversial. PATIENTS AND METHODS We analyzed 262 patients with centralized basal Ki67 immunohistochemical evaluation derived from 4 GEICAM (Spanish Breast Cancer Group) clinical trials of ...
background and objective: the association of ebv with hodgkin lymphoma (hl) has been intensely investigated over the last few years. ebv is also associated with several other malignancies. on the other hand, ki67 molecule serves as a widely accepted proliferation marker. several studies were previously performed about the expression of ki67 in hd. this study tried to detect the correlation betw...
UNLABELLED Nodular fasciitis is the most common pseudosarcomatous lesion of soft tissue. Ki67 was considered as a useful marker for distinguishing some benign and malignant lesions. To study the usefulness of Ki67 in diagnosis of nodular fasciitis, the expression of Ki67 was examined by using immunostaining in 65 nodular fasciitis specimens, 15 desmoid fibromatosis specimens and 20 fibrosarcoma...
