Ovarian influence on adrenal androgen secretion in polycystic ovary syndrome

OBJECTIVE To determine whether the ovary influences adrenal androgen secretion in polycystic ovary syndrome (PCOS). DESIGN The adrenal androgen secretion was evaluated before and during ovarian suppression with a long-acting GnRH agonist. SETTING Department of Obstetrics and Gynecology, Pisa, Italy. PARTICIPANTS Women with PCOS and high (10 subjects) and normal (12 subjects) DHEAS levels and 6 normal women. INTERVENTIONS After 1 mg dexamethasone, an ACTH-(1-24) stimulation test was performed in the early follicular phase of the menstrual cycle. The test was repeated after two injections of a long-acting GnRH analogue (GnRH-a). MAIN OUTCOME MEASURES Basal plasma levels of gonadotropins, E2, T, androstenedione (A), 17 alpha-hydroxyprogesterone (17-OHP), DHEAS, and cortisol (F) were evaluated before the evening administration of dexamethasone. Serum A, T, 17-OHP, DHEAS, and F were measured 9 hours after dexamethasone and in samples collected 60 and 120 minutes after ACTH IV injection. RESULTS In the high DHEAS group the maximum increases in T, A, 17-OHP, and DHEAS in response to ACTH were significantly higher than in normal DHEAS PCOS women and in normal women. The GnRH-a modified the A and T responses to ACTH in the high DHEAS group. CONCLUSIONS Ovarian steroids, or other extra-ovarian factors, seem to be responsible for the increased A and T responses to the corticotropin stimulation demonstrated in some PCOS women.

The clinical outcome of epithelial ovarian cancer patients with apparently isolated lymph node recurrence: A multicenter retrospective Italian study

OBJECTIVES To assess the clinical outcome of epithelial ovarian cancer patients who developed an apparently isolated lymph node recurrence after primary therapy. METHODS The authors retrospectively assessed 69 patients with epithelial ovarian cancer who were clinically or pathologically free of disease after primary therapy and who subsequently developed an apparently isolated lymph node recurrence. The median follow-up of survivors was 74.5 months. RESULTS Median age was 58 years, FIGO stage was III-IV in 52 (75%) patients, residual disease after primary surgery was >1 cm in 36 (52%), first-line chemotherapy consisted of paclitaxel-/platinum-based chemotherapy in 44 (64%), time to recurrence was >12 months in 43 (62%), recurrence was pelvic and/or para-aortic in 41 (59%), and treatment at recurrence consisted of chemotherapy alone in 44 (64%), surgery plus chemotherapy in 22 (32%), surgery alone in one patient, surgery plus irradiation in one, and irradiation alone in one patient. Survival after recurrence was significantly related to the type of treatment (chemotherapy alone versus surgery plus chemotherapy, median: 20.8 months versus not reached, p=0.0002), and patient age (>58 versus <58 years, median: 26.8 versus 44.0 months, p=0.02). Overall survival was significantly related to the type of treatment (chemotherapy alone versus surgery plus chemotherapy, median: 45.4 months versus not reached, p=0.0001), patient age (>58 versus <58 years, median: 45.4 versus 62.9 months, p=0.03) and time to recurrence (<12 months versus >12 months, median: 45.4 versus 66.9 months, p=0.01). Cox model showed that treatment at recurrence was the strongest independent prognostic variable for both survival after recurrence (hazard ratio [HR]=0.277, p=0.0003) and overall survival (HR=0.249, p=0.0002). CONCLUSION Patients who underwent surgery plus chemotherapy had a 72% reduction in the risk of death after recurrence and a 75% reduction in the risk of death after initial diagnosis when compared with those treated with chemotherapy alone. Secondary cytoreductive surgery appears to be able to prolong survival in epithelial ovarian cancer patients with apparently isolated lymph node recurrence.
