Abstract:
The estrogen receptor content was measured in 25 primary human mammary carcinomas. These values were compared to those in metastases which were detected between 0-108 months after mastectomy. There was a good correlation between the receptor level in the primary tumor and in its metastasis. This finding does not support the hypothesis that metastases in general represent a selection of poorly differentiated receptor-poor cell clones from the primary tumors.
