Figure 4.
Simulation of RFS in patients with 10 or more positive axillary nodes following maximally intensive therapy, assuming different proportions of patients with sensitive tumours ranging from 0 to 1.0, in 0.1 increments. Treatment of maximally tolerated intensity is assumed to produce a 9 log cell kill in sensitive tumours, and is assumed to produce no effect on resistant tumours. For reference, the value for RFS at 5 years following treatment of maximal intensity using the Peters regimen (Peters et al, 2000) is shown (open circle), corresponding to an estimated probability of a chemosensitive tumour equal to 0.48.
