DNA index as prognostic factor in breast cancer.

Enzymatically dissociated cells exhibited growth in most cases while mechanically dissociated cells did not grow in short term cultures and were not suitable for cytometric study. Breast cancer cells obtained by enzymatic dissociation were examined for DNA content and S-phase fraction. The most of the primary and metastatic breast cancer cells were aneuploid.

Enzyme activities and level of SH groups in breast carcinomas.

1. The carcinoma showed higher enzyme activities than the normal mammary tissue. 2.
