This study has been approved by the ethical committee of both the San Raffaele Hospital and the Santa Chiara Hospital. HER2 Testing Methods HER2 expression on both breast malignancy cell lines and tissue macro-arrays was detected by immunohistochemistry (IHC) using HercepTest (Dako, Carpinteria, CA). Results were scored by intensity and percentage of staining on a level from 0 to 3+ according to the American Society of Clinical Oncology/College of American Pathologists guidelines [2]. Fluorescence hybridization (FISH) screening for was performed on the same samples using the PathVysion HER2 DNA Probe Kit (Abbott Molecular, Abbott Park, IL) according to the manufacturer’s instructions. Slides were analyzed using Nikon 90i fluorescence microscope (Nikon Devices SpA, Florence, Italy) with both a single-pass (green and orange) and a triple-pass filter band [4,6-diamidino-2-phenylindole (DAPI)/green/orange]; images were captured by Genikon software (Nikon). A total of 100 neoplastic nuclei were observed per each sample and FISH scoring ranges were based on those decided for the US Food and Drug Administration-approved test for gene alterations in breast cancer using a combined genecentromere probe [32,33]. Immunohistochemistry All immunostains were performed after microwave oven heat-based antigen retrieval, using citrate buffer at pH 6.0. The following anti-CDC25A antibody clones were tested: 3H2016, 144, F-6, N-15, M-191, 5H51 (Santa Cruz Biotechnology, Santa Cruz, CA), Ab991, Ab989 (Abcam, Cambridge, MA), DCS-120 (Thermo Scientific, Newington, NH), 3652 (Cell Signaling Technology, Danvers, MA), C25600-01U (USBio, Swampscott, MA), and PC733 (Merck Bio, Birmingham, United Kingdom). The best results were achieved with the primary antibody anti-human CDC25A [rabbit polyclonal (144), sc-97; Santa Cruz Biotechnology; 1:500 dilution]. The specificity of the immunostaining was also examined by a pre-absorption test. The diluted main antibody was mixed with a fivefold (by excess weight) excess of the antigenic peptide (CDC25A 144 P sc-97P; Santa Cruz Biotechnology) in a small volume (500 l) of phosphate-buffered saline and incubated for 2 hours at room heat (RT) before being used in the immunostaining. Microscopic observation was performed using a Nikon Eclipse 80i and images were captured and analyzed using Aperio ScanScope and Aperio ImageScope Nuclear Algorithm (Nikon Devices Health spa). The median percentage of positive nuclei for CDC25A staining (19%) was regarded as cutoff.
