The key difference between our study and that of Holst et al.1 is the methodology for scoring FISH-TMA (manual vs. automated) and the criteria used to call amplifications. Holst et al.1 scored as amplified not only cases with an ESR1 to centromere 6 ratio ≥2 but also “tumors with tight signal clusters...independent… CONTINUE READING
