RESUMO

PURPOSE: Adequate androgen levels are necessary for regular follicular growth, progression beyond the pre-antral stage, and prevention of follicular atresia. The main purpose of this study was to investigate whether baseline androgen levels had a predictive value on stimulation outcomes in IVF cycles. The secondary purpose was to compare the possible predictive value of androgens with that of already known markers. METHODS: The study included 91 infertile patients aged 30-45 years awaiting the first IVF cycle. All women underwent the same stimulation protocol and the same starting dose of recombinant FSH. As stimulation outcomes, the number of follicles recruited, estradiol and progesterone levels on the day of trigger, the total dose of gonadotropins administered, and the number of oocytes collected were recorded. Multiple linear regression and multivariate logistic regression were used to evaluate the significant predictive value of the variables for response to controlled ovarian stimulation (COS). By studying the reliability of different markers, an attempt was made to develop a single index with the highest predictive value. RESULTS: Pearson's correlation revealed a statistically significant inverse correlation between oocytes collected and age (r = - 0.333, p < 0.001) and a positive correlation with AMH (anti-müllerian hormone) (r = 0.360, p < 0.001), antral follicle count (AFC) (r = 0.639, p < 0.001), and androstenedione (Δ4-A) (r = 0.359, p < 0.001). No significant correlation was reported with FSH (r = - 0.133, p = 0.207) and total testosterone (r = 0.180, p = 0.088). In COS good responders, the G-index (= AMH ng/mL*AFC/Δ4-A ng/dL) revealed a significantly higher level (p < 0.001) than AMH, AFC, and Δ4-A alone. CONCLUSION: Baseline serum Δ4-A, presumably crucial for ensuring a regular follicular growth, is a reliable marker of ovarian response to stimulation. Since the ovarian capacity to respond to gonadotropins does not depend exclusively on the presence of follicles, we suggest a new index, the G-index, able to contemplate both the ovarian reserve and the Δ4-A level.

RESUMO

OBJECTIVE: To evaluate the long-term outcomes of young early stage cervical cancer patients wishing to preserve their childbearing potential. METHODS: Data of young (aged <40 years) patients with early stage cervical cancer were prospectively collected. All patients with stage IA2, IB1 and IB2 cervical cancer were included; they have cervical conization and pelvic node dissection performed via minimally invasive surgery. Survival outcomes were assessed with the Kaplan-Meier model. RESULTS: Overall, 32 patients met the inclusion criteria. Mean (SD) age of the population included was 33 (±4). According to the FIGO 2018 staging system, the stage of disease was IA2, IB1 and IB2 in 9 (28%), 21 (66%) and 2 (6%) cases, respectively. All patients included had cervical conization and laparoscopic pelvic node assessment, including systematic pelvic lymphadenectomy (N = 30, 94%) and sentinel node mapping (N = 2, 6%). In six (19%) patients the planned conservative treatment was discontinued. Median follow-up was 75 (range, 12-184) months. No recurrent disease was diagnosed among patients undergoing conservative treatment; while 2 out of 6 patients having definitive surgical or radiotherapy treatments developed recurrent disease. Five-year disease free and overall survivals were 94% and 97%, respectively. Considering reproductive outcomes, 11 (69%) out of 16 patients who attempted to conceive got pregnant. CONCLUSIONS: Cervical conization and pelvic nodes assessment could be considered a valid treatment modality for early-stage cervical cancer patients who are wishing to preserve their childbearing potential.

RESUMO

Hyperandrogenism is a condition affecting 5-10% of adolescents. The aim of this study was to evaluate the efficacy of very low dose of flutamide in the treatment of hyperandrogenism in adolescence. One hundred and fifty-eight patients, presenting severe acne and/or hirsutism, received 62.5 mg/day of flutamide + ethinylestradiol + gestodene for 18 months. The patients were subjected to assessments of hepatic enzymes levels. Thirty subjects treated with drospirenone + ethinylestradiol represented the control group. After 18 months of treatment, it was obtained a decrease of hirsutism (-39.9%), an almost recovery of acne (98% of patients) with better results of those obtained in control group. Only one case of light hypertransaminasemia was recorded, regressed spontaneously. Very low dose of flutamide was successful and safe and in the treatment of hyperandrogenism in adolescence.
