Figure Lengend Snippet: EndoPredict test results achieved after different storage times and temperatures before fixation. The solid line represents the reference score which was derived from the mean EP score of the tissue sections that have been stored for 10 min at 20 °C before fixation. Dotted lines represent the reference score ±3× its standard deviation as determined by precision study . Measurements were performed in duplicate ( n = 2). Mean values are presented, with standard errors of the means indicated by bars

Article Snippet: EndoPredict tests (Sividon Diagnostics, Cologne, Germany) were performed as previously described using SuperScript III PLATINUM One-Step Quantitative RT-PCR System (Life Technologies, Darmstadt, Germany) and VERSANT kPCR Molecular System (Siemens Healthcare Diagnostics, Tarrytown, USA) [ , ].

Techniques: Derivative Assay, Standard Deviation

Figure Lengend Snippet: Correlation between the EP ( a ) and EPclin ( b ) scores of paired whole and tumor-enriched, manually microdissected tissue sections from ER+/HER2− breast cancer patients ( n = 39). Pearson correlation coefficient of EP scores was 0.97 with a concordance of EndoPredict risk classification of 87 %. Pearson correlation coefficient of EPclin scores was 0.98 with a concordance of EndoPredict risk classification of 95 %. Black filled circles represent tissue samples with TCC ≥30 %, open circles tissue sections with TCC <30 %

Figure Lengend Snippet: Correlation of EP scores between stored and nonstored FFPE tissue sections. EP scores have been determined at the beginning of the study, after 12 months at +4 °C ( a ) or after 12 months at +20 °C ( b ), respectively. Pearson correlation coefficients were 0.99 and >0.99 with a concordance of EndoPredict risk classification of 100 %
