Stratification using NPI+ of those patients in the various classes who received adjuvant chemotherapy for groups (A) luminal (1+2+3), (B) basal (4+5), (C) two basal groups—patients with Basal p53 normal tumours had a good survival overall and no additional stratification could be achieved. (D) HER2 (6+7), (E) HER2+/ER+ and (F) ER+/ER−. There were too few luminal cases receiving chemotherapy to allow development of NPI+ formulae for each of the luminal groups. It can be seen that NPI+ identifies patients with favourable vs poor outcome in all classes assessable apart from the Basal p53 normal class. Time is shown in months.
