title: DNA and oestradiol receptor distribution in human breast cancer.
abstract: The content of DNA and oestradiol receptors was measured in two different samples taken from the same tumoral mass of 33 primary infiltrating ductal carcinomas. The results were related to the total cytoplasmic protein and to the DNA of the tissue. The results showed that variations of both DNA and oestradiol receptors are frequent and often significant. The reliability of analyses carried out on a single biopsy is discussed.
