HER-2/neu Amplification Testing in Breast Cancer by Multiplex Ligation-Dependent Probe Amplification in Comparison with Immunohistochemistry and In Situ Hybridization
BACKGROUND Assessment of HER-2/neu status in invasive breast cancer is crucial to establish eligibility for trastuzumab and taxane based chemotherapy. Next to immunohistochemistry (IHC) to evaluate protein overexpression, a second line gene amplification test is required for cases with equivocal protein expression. This study aimed to validate a new PCR based test, called Multiplex Ligation-dep...
متن کاملApplications of multiplex ligation-dependent probe amplification (MLPA) method in diagnosis of cancer and genetic disorders
Introduction: Lots of human diseases and syndromes result from partial or complete gene deletions and duplications or changes of certain specific chromosomal sequences. Many various methods are used to study the chromosomal aberrations including Comparative Genomic Hybridization (CGH), Fluorescent in Situ Hybridization (FISH), Southern blots, Multiplex Amplifiable Probe Hybridisation (MAP...
متن کاملDetection 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...
متن کاملClonal profiling of mixed lobular and ductal carcinoma revealed by multiplex ligation-dependent probe amplification and fluorescence in situ hybridization.
A needle biopsy of a mass in the right breast of a 36-year-old woman revealed invasive ductal carcinoma (IDC), and approximately 20% of cancer cells showed unequivocal membranous staining with the HercepTest. After systemic therapy with trastuzumab and paclitaxel followed by FEC (fluorouracil + epirubicin + cyclophosphamide), a right mastectomy was performed. By histological and immunohistochem...
متن کاملLigation-independent mechanism of multiplex ligation-dependent probe amplification.
Multiplex ligation-dependent probe amplification (MLPA) is a widely used technique for detecting genomic structural variants. The technique is based on hybridization and ligation, followed by amplification of the ligation products. Therefore, ligation is considered a fundamental process that determines the feasibility and fidelity of MLPA. However, despite the widespread use of this technique, ...
