    Abstract:
    From 1977 to 1981, 39 cases of primary cervical carcinoma were assayed for the presence or absence of cytoplasmic estrogen (ERc) and progesterone (PRc) receptors by a saturation point dextran-coated charcoal assay. The levels of ERc and PRc were compared with clinical stage, histologic type, histologic grade, menstrual status, age, and survival. Carcinomas were divided into positive and negative receptor groups with the use of greater than 5 fmol/mg of cytosol protein for ERc and 10 fmol/mg of cytosol protein for PRc as discrimination points. Survival of the patients studied was computed by means of the product-limit analysis according to Kaplan-Meier. A statistically significant difference in survival in the PRc + group versus the PRc - group in the total group of patients was noted with the Mantel-Cox test (P = 0.049). When patients were stratified according to menopausal status, a statistically significant difference in survival was noted between the PRc + group versus the PRc - group in the premenopausal patients only.
