73%
TAILORx patients saved from over-treatment
43%
with low clinical risk* saved from under-treatment
TAILORx shows that clinical risk features alone are not sufficient to determine chemotherapy benefit1,2
73% of patients in TAILORx with high clinical risk* had Recurrence Score results 0-25 and may have been overtreated without the Recurrence Score result**2
43% of patients in TAILORx with Recurrence Score results 26-100 had low clinical risk* and may have been undertreated without the Recurrence Score result**2
*Low clinical risk: tumour size ≤3 cm and Grade 1; tumour size ≤2 cm and Grade 2; tumour size ≤1 cm and Grade 3; High clinical risk: all other cases with known values for grade and tumour size
