It's 3rd generation based on "predict" information for professionals, I'm guessing this is why you are asking:
The model is easy to use following data entry for an individual patient including patient age, tumour size, tumour grade, number of positive nodes, ER status, HER2 status, KI67 status and mode of detection. Survival estimates, with and without adjuvant therapy, are presented in visual and text formats. Treatment benefits for hormone therapy and chemotherapy are calculated by applying relative risk reductions from the Oxford overview to the breast cancer specific mortality. Predicted mortality reductions are available for both second generation (anthracycline-containing, >4 cycles or equivalent) and third generation (taxane-containing) chemotherapy regimens.
