OBJECTIVES: According to the 2004 Bioethics Act, oncofertility counselling must be systematically offered to all women of childbearing age before they are exposed to potentially gonadotoxic treatment. The main objective of this study was to evaluate the proportion of women under 40 years of age treated with chemotherapy for breast cancer in Midi-Pyrénées who have received an oncofertility consultation. A secondary objective was to assess practitioners' knowledge on the subject. METHODS: A cross-reference was made between the databases of the oncology network in Midi-Pyrénées and the two approved centres for the preservation of fertility in the region. A computerized practitioner questionnaire was sent to all surgeons and oncologists who could manage these patients. RESULTS: From 2012 and 2017, 667 women aged≤40 years received (neo)adjuvant chemotherapy treatment: only 156 (23.4%) had access to an oncofertility consultation and 58 (8.7%) received preservation. This rate (23.4%) varied according to the age of the patients, ranging from 56.9% for those aged 25-29 to 13.4% for those aged 35-39 and the managing institution. Of the 85 practitioners surveyed, 45 (55%) responded to the questionnaire, and of these 20 (44%) knew that ovarian stimulation treatment could be used even in hormone-dependent breast cancer situations and 13 (29%) of practitioners believed that the time required to preserve fertility was more than 1 month. CONCLUSION: Our study revealed a significant disparity in access to oncofertility consultation. It is essential to set up information and awareness-raising actions on the subject.

OBJECTIVE: To determine the clinical characteristics of pubertal metrorrhagia and its treatment, depending on severity; to evaluate the frequency of etiologies and the influence of hemostatic abnormalities; and to describe severe pubertal metrorrhagia. Design, setting and participants. This retrospective study examined all the files (n = 105) of adolescents presenting for pediatric gynecology consultation at a children's hospital between January 1979 and June 1993. RESULTS: The mean age of patients at the first consultation was 13 years. Metrorrhagia began in the year after the first menstrual period in 85% of cases. The causes were functional (83 cases), primary hemostatic disorder (14 cases), hemostatic disorder secondary to renal or hepatic disease (7 cases), or tumor (1 case). The cases were assigned to one of three groups, according to the severity of anemia; group I, mild anemia, hemoglobin Hb > 11 g%, 64 cases; group II, moderate anemia, Hb 8-11 g%, 23 cases; and group III, severe anemia, Hb < 8 g%, 18 cases. Of the 14 patients suffering from primary hemostatic disorders, 7 had been diagnosed before the onset of metrorrhagia; the disorder was revealed by the metrorrhagia in the remaining 7. Only 1 of these patients was severely anemic (known factor X deficiency). Four patients suffering from moderate von Willebrand's disease were discovered after specific tests; they were mildly or moderately anemic. The severe anemias (group III) all occurred during the first three periods. This group had functional disorders in 15 of 18 cases. Treatment continued to be required in 10 of 18 cases followed for more than 3 years. Treatment was progestin for group I and II patients or an estroprogestin, followed by a progestin, for group III. Curettage was never required. CONCLUSIONS: The most common cause of pubertal metrorrhagia is a functional disorder (80% of cases). Hemostatic disorders likely to cause severe menstrual hemorrhage were known before the age of menarche; these disorders must be controlled by hormone treatment begun before or at the time of the first menstrual period. Severe forms that arise during the initial three menstrual cycles are functional in most cases. These should be given a course of treatment lasting several years. There is a high risk of recurrence. Treatment is medical and hormonal in all cases.

Long cycles and excessive uterine bleeding are the most common menstrual disorders in adolescents. Long cycles usually result from a benign transitory functional disorder which spontaneously resolves within two to three years after menarche; however, this diagnosis can only be retained in the absence of hirsutism or galactorrhea as revealing symptoms of functional ovarian hyperandrogenism, polycystic ovary syndrome, late form of congenital adrenal hyperplasia or hyperprolactinemia; ovarian failure will be considered in case of isolated long cycles persisting more than two years after menarche. Excessive uterine bleeding usually occurs early after menarche. Although the main cause is functional, resulting from anovulation and the related absence of progesterone, coagulation disorders must always be excluded. Management of these disorders are described.

BACKGROUND: Adrenal ganglioneuroma (GN) is seldom considered in the differential diagnosis of adrenal lesions, and its clinical presentation is not well known. OBJECTIVE: Our aim was to describe the clinical, biochemical, and radiological features of adrenal GNs in adults. METHODS: Seven adults underwent endocrine investigation for adrenal lesions that were confirmed to be adrenal GNs. RESULTS: Mean age of the seven patients was 49 yr (range, 23 to 71 yr). Average tumor diameter was 5.0 cm (range, 1.5 to 10.4 cm). In five patients, the adrenal lesions were found incidentally. A 49-yr-old female carried a germline mutation in MSH2 gene. A 57-yr-old female presented with mild virilization and increased testosterone levels. Bilateral adrenal venous sampling revealed testosterone production from her right adrenal lesion. All tumors showed nonenhanced attenuation between 25 and 40 Hounsfield units on computed tomography scan. Magnetic resonance imaging revealed low- to iso-signal intensity on T1-weighted imaging and high-signal intensity on T2-weighted imaging. [(18)F]-2-Fluoro-deoxy-d-glucose-positron emission tomography scan (n = 5) disclosed a mean standard uptake value of 2.4. Three tumors were composite pheochromocytoma-GN. Microsatellite instability study and immunohistochemical analysis of MSH2 protein in a patient carrying a MSH2 mutation showed normal MSH2 protein expression and low microsatellite instability, indicating that the adrenal GN was not related to the patient's MSH2 germline defect. CONCLUSIONS: We describe one of the largest series of adult adrenal GNs. Adrenal GNs may secrete testosterone or be part of a composite tumor with pheochromocytoma. The association of adrenal GN with MSH2 mutation seems to be a coincidental finding.

The diagnosis of recurrent ovarian cancer can be difficult on cross-sectional imaging, and variable sensitivities and specificities have been reported for positron emission tomography (PET). Combined functional and anatomic imaging with PET plus computed tomography (CT) potentially allows for improved detection of tumor masses. We investigated the sensitivity, specificity, and accuracy of PET-CT for the diagnosis of recurrent ovarian cancer. Sixteen women with previously treated ovarian cancer underwent imaging on a combined PET-CT scanner followed by surgery to assess for possible recurrent disease. The fused PET-CT images were retrospectively reviewed for recurrent disease, and the results of PET-CT were compared with the operative notes. Eleven of the 16 patients had recurrent disease at surgery. The sensitivity, specificity, and accuracy of PET-CT for disease detection on a per-patient basis were 72.7%, 40%, and 62.5%, respectively. For cases of malignant adenopathy (n = 7), 100% were detected on PET-CT. For peritoneal lesions no larger than 1 cm (n = 23), 13% were detected on PET-CT. For peritoneal lesions larger than 1 cm (n = 8), 50% were detected on PET-CT. The sensitivity of PET-CT for recurrent ovarian cancer is moderate in patients with low volume disease. A trial involving a larger number of patients with a spectrum of disease volumes is necessary to determine the impact of PET-CT in clinical practice.

BACKGROUND: We assessed the contribution of dedicated computed tomographic (CT) interpretation to the accuracy of positron emission tomography (PET) plus CT in imaging patients with suspected primary or metastatic colorectal carcinoma. METHODS: One hundred PET/CT scans in 90 consecutive patients were evaluated retrospectively. Imaging was performed on a GE Discovery LS PET/CT scanner. PET images were obtained from the skull base through the midthigh after intravenous administration of 15 to 20 mCi of [(18)F] fluorine-18-fluoro-2-deoxyglucose. Noncontrast axial CT images were obtained at the same anatomic locations, with 140 kV, 80 mA, 0.8 s/CT rotation, a pitch of 6, and a table speed of 22.5 mm/s. The CT component of the PET/CT study was reviewed independently by consensus of two blinded readers. Scans were evaluated for the presence of primary disease, local recurrence, and distant metastases. Results were compared with the PET/CT report. The gold standard was clinical and imaging follow-up for at least 6 months, surgery, or biopsy. RESULTS: The study included 40 males and 50 females, with a mean age of 63 years (range, 31-92 years). The indications for the examination were to evaluate for recurrence of colorectal cancer in 83 cases, determine disease spread in 15 cases, and evaluate for possible primary malignancy in two cases with rising carcinoembryonic antigen. Sensitivity, specificity, and accuracy of the PET/CT report and of the combined PET/CT with dedicated CT interpretation were 0.914, 0.633, and 0.830 and 0.986, 1.000, and 0.980, respectively. The difference between PET/CT and the combined PET/CT with dedicated CT interpretation with respect to accuracy was statistically significant (p < 0.05). CONCLUSION: The CT portion of PET/CT provides valuable anatomic and pathologic information to the functional information provided by PET and helps improve the overall accuracy of the combined study.
