Detection of HER2 and Topo 2 in breast cancers: comparison between MLPA and FISH approaches.

Detection of HER2 Amplification in Breast Carcinomas: Comparison of Multiplex Ligation-Dependent Probe Amplification (MLPA) and Fluorescence In Situ Hybridization (FISH) combined with Automated Spot Counting

In this study the detection of HER2 gene amplification was evaluated using Fluorescence In Situ Hybridization (FISH; PathVysion) in comparison with Multiplex Ligation-dependent Probe Amplification (MLPA), a PCR based technique. These two methods were evaluated on a series of 46 formalin fixed paraffin embedded breast carcinomas, previously tested for protein overexpression by HercepTest (groupe...

Imaging features of estrogen-negative breast cancers: a correlation study with human epidermal growth factor type II overexpression

Background: Estrogen-negative breast cancers have different clinical course, prognostic features and treatment response in comparison to estrogen receptor-positive (ER-positive) breast cancers. Human epidermal growth factor receptor 2 (HER2) oncoprotein has found to have a pivotal role in natural cell growth and cell division and is suggested to be directly related to tumor invasiveness in brea...

HER2 Testing in Invasive Breast Cancer: a Comparison between Immunohistochemistry and FISH Assays

Multiplex Ligation-Dependent Probe Amplification to Detect HER2 Amplification in Breast Cancer: New Insights in Optimal Cut-Off Value

In Volume 31 of Cellular Oncology (2009), we published an article titled “HER2-neu amplification in breast cancer by multiplex ligation-dependent probe amplification in comparison with immunohistochemistry and in situ hybridization” [3]. To analyze our multiplex ligation-dependent probe amplification (MLPA) data we used a cut-off value of 1.5 to discriminate between HER2 non-amplified and low-l...

بررسی فراوانی جهش‌های مضاعف شدگی ژنHER2/neu در بیماران مبتلا به سرطان معده با استفاده از تکنیک تکثیر پروب وابسته به الحاق چندتایی

Background and aims:  Gastric malignancies have the fourth place among the most prevalent cancers. In many cancers, overexpressing of HER2/neu gene has been observed with a poor prediction. Up to now, there is a little information about the duplication of HER2/neu gene in gastric cancer using MLPA method. The present study aimed to investigate the frequency of mutations resulting from ampl...
