title: RNA:DNA ratios in human tumors.
abstract: A study has been made of the quantitative relation existing between the RNA:DNA ratios in benign and in malignant human tumors. It has been demonstrated that a significant difference (Student's t-test) existed between malignant and benign human tumors within the different groups studied: a) malignant and benign breast tumors (t=2.22, P less than 0.05); b) Hodgkin's disease in spleen and its controls (t=2.39, P less than 0.02); and c) malignant and benign thyroid tumors (t=4.23, P less than 0.01). The diagnostic value of this finding is discussed.
