From: Recurrence and mortality according to Estrogen Receptor status for breast cancer patients undergoing conservative surgery. Ipsilateral breast tumour recurrence dynamics provides clues for tumour biology within the residual breast

Figure 5

Hazard rate estimates for IBTR in 1615 ERP tumours and in 427 ERN tumours from patients undergoing conservative surgery (quadrantectomy or tumourectomy) plus RT. The dynamics of recurrence within the same breast irradiated following tumourectomy or quadrantectomy is quite distinct and different depending upon whether the resected tumor does or does not bear sex hormone receptors. Vertical lines represent point-wise confidence interval for the model estimated hazards, according to standard asymptotic theory.
