Postpartum haemorrhage after induced and spontaneous labour

an objective remission in one patient who underwent hormonal ablation and was shown to be ER-negative, PgR-positive. I hope that the above-cited references will correct the impression that only ER-positive tumours contain PgR. Although the number of cases of PgR-positive, ER-negative tumours is small, they do exist. The importance of recognising this group ofmammary carcinomas is that it may provide new insights into the interrelationship that exists between various hormones, their receptors, and tumour regression.
