Objective:To analyze the levels of endogenous sexual steroids and gonadotrophin in women with and without endometrial cancer. Methodology:We developed a clinical comparative study on 20 postmenopausal women with endometrial cancer and 20 postmenopausal women without endometrial cancer. The age, the postmenopausal time and the index of body mass were used as matching variables. The plasma levels of the endogenous sexual steroids were measured using radioimmunoassay and immunoenzymatic methods. For the statistic analysis we used the Student's t test. Results: The levels of androstenedione (A), total testosterone (t) and free testosterone (TL) were higher in the women with endometrial cancer, and those of the luteinic hormone (LH) were significantly lower values in these women. We also observed that the ratio (E1/A) showed significantly lower in the group of women with cancer, while the ratio (E2/E1) did not present any differences between groups. Conclusions: We emphasize the potentiality of sexual steroids and gonadotrophins in the genesis of endometrial adenocarcinoma in postmenopausal women.

PURPOSE: to evaluate the relationship between epidemiologic, anthropometric, reproductive and hormonal factors and mammographic density in postmenopausal women. METHODS: this is a retrospective, cross-sectional study, including 144 women aged 45 years or more, with at least 12 months of amenorrhea and who were non users of hormone replacement therapy during the last six months. Medical charts were reviewed to evaluate age, weight, body mass index (BMI), parity, age at menarche, age at menopause and levels of estradiol, follicle stimulating (FSH) and luteinizing hormones. Mammograms were analyzed by two blinded investigators. The films were taken in the craniocaudal and mediolateral views and mammography was classified as dense and nondense, according to the Wolfe criteria. For statistical analysis, the frequency, median, minimum and maximum values, the Wilcoxon test and the odds ratio were used. Multiple logistic regression was performed, using the stepwise selection, with a 5% significance level. RESULTS: the frequency of dense breasts was 45%. Women with dense breasts were of lower weight (60.5 vs. 71.9 kg - p<0.01), had a lower BMI (25.9 vs 31.0 kg/m² - p<0.01), a shorter time since onset of menopause (6.0 vs 10 years - p<0.01) and higher levels of FSH (75.2 vs 60.3 mU/mL - p<0.01). The probability of having dense breasts decreased in women whose weight was 67 kg or more (OR = 4.0, CI 95% = 1.50-10.66), BMI was higher than 30 kg/m² (OR = 6.69, CI 95% = 1.67-36.81), time since onset of menopause was superior or equal to seven years (OR = 2.05, CI 95% = 1.05-3.99) and FSH levels were lower than 134.8 mU/mL. CONCLUSION: weight, BMI, parity, time since menopause and FSH levels were significantly associated with mammographic density patterns.
