Arising from: Abdullah-Sayani A et al. (2006) Nat Clin Pract Oncol 3: 501–516

I was surprised to read the conflict of interest statement for the review by review Abdullah et al. where they declare no conflicts of interest.1 If one reads the fine print, authors have made a frontal attack on Oncotype Dx® (though it is correct and completely justified). However, I feel they should declare that they are involved in 70-gene signature and MammaPrint® (other competing commercial chip), just for the sake of ethical issues.
