RESUMO

OBJECTIVE: To assess whether corifollitropin-α (CFα) late-start administration (day 4) and standard administration (day 2) can obtain similar oocyte yield and live birth rate. STUDY DESIGN: A randomized controlled trial. SETTING: University Hospital IVF Unit. PATIENTS: One hundred thirteen women undergoing IVF. INTERVENTIONS: Patients distributed in three subgroups (expected poor, normal, or high responders to FSH) were randomized into two treatment arms: (a) CFα late-start: CFα on day 4 + GnRH antagonist from day 8 + (when needed) recFSH from day 11; (b) CFα standard start: CFα on day 2 + GnRH antagonist from day 6 + (when needed) recFSH from day 9. IVF or ICSI was performed as indicated. RESULTS: Considering the whole study group, the late-start regimen obtained comparable oocyte yield (8.9 ± 5.6 vs. 8.8 ± 6.2; p = n.s.), cPR/started cycle (25% vs. 31.6%, p = n.s.), and cumulative live birth rate (LBR)/ovum pickup (OPU) (29.2% vs. 37.7%, p = n.s.) than the standard regimen. The outcome of the two regimens was comparable in the two subgroups of high and normal responders. Differently, in poor responders, oocyte yield was similar, but LBR/OPU was significantly lower with late-start CFα administration that caused 40% cancellation rate due to monofollicular response. ROC curves showed that the threshold AMH levels associated with cycle cancellation were 0.6 ng/ml for late-start regimen and 0.2 ng/ml for standard regimen. CONCLUSION: CFα may be administered on either day 2 or day 4 to patients with expected high or normal response to FSH without compromising oocyte yield and/or live birth rate. Differently, late-start administration is not advisable for expected poor responders with AMH ≤ 0.6 ng/ml. TRIAL REGISTRATION: NCT03816670.

RESUMO

In the last years, thanks to the improvement in the prognosis of cancer patients, a growing attention has been given to the fertility issues. International guidelines on fertility preservation in cancer patients recommend that physicians discuss, as early as possible, with all patients of reproductive age their risk of infertility from the disease and/or treatment and their interest in having children after cancer, and help with informed fertility preservation decisions. As recommended by the American Society of Clinical Oncology and the European Society for Medical Oncology, sperm cryopreservation and embryo/oocyte cryopreservation are standard strategies for fertility preservations in male and female patients, respectively; other strategies (e.g. pharmacological protection of the gonads and gonadal tissue cryopreservation) are considered experimental techniques. However, since then, new data have become available, and several issues in this field are still controversial and should be addressed by both patients and their treating physicians.In April 2015, physicians with expertise in the field of fertility preservation in cancer patients from several European countries were invited in Genova (Italy) to participate in a workshop on the topic of "cancer and fertility preservation". A total of ten controversial issues were discussed at the conference. Experts were asked to present an up-to-date review of the literature published on these topics and the presentation of own unpublished data was encouraged. On the basis of the data presented, as well as the expertise of the invited speakers, a total of ten recommendations were discussed and prepared with the aim to help physicians in counseling their young patients interested in fertility preservation.Although there is a great interest in this field, due to the lack of large prospective cohort studies and randomized trials on these topics, the level of evidence is not higher than 3 for most of the recommendations highlighting the need of further research efforts in many areas of this field. The participation to the ongoing registries and prospective studies is crucial to acquire more robust information in order to provide evidence-based recommendations.

RESUMO

This communication reports a novel technical solution for the orthotopic transplant of cryostored-thawed ovarian tissue. The described technique was applied to three young women with iatrogenic ovarian failure. An echogenic thread that is reabsorbed after 6 months was used to fasten the thawed ovarian small fragments before grafting them onto the atrophic ovary. This technical solution made it possible to avoid the loss of small tissue pieces during laparoscopic grafting as well as to precisely localize the grafted tissue by transvaginal ultrasound during the following months. The precise localization of the grafted tissue was particularly helpful when its revascularization and functional recovery were followed up using, respectively, colour Doppler and transvaginal follicle growth examination. In conclusion, the use of a slowly reabsorbed, ultrasound-detectable surgical thread as an ultrasound-detectable marker able to improve the localization of the exact site at which ovarian tissue was grafted is proposed.

RESUMO

Fertility preservation programs (FPPs) based on oocyte or ovarian tissue cryostorage may be offered to women facing oncostatic treatments at risk of precocious ovarian insufficiency. The way in which FPPs are presented to patients affects their decision to join them. We studied herein 48 young women to whom a FPP was proposed, aiming at clarifying the emotional aspects involved. A psychologist attended the consultations in which the FPP was offered to patients; at the end of the talk, a questionnaire was administered and a semi-structured interview was carried out. Finally, the STAI test was administered to measure trait (TAI) and state (SAI) anxiety, both immediately after consultation, and later on, when patients returned home. We observed that the possibility to join a FPP implied important emotional aspects, and that the presence of a psychologist was helpful to integrate technical information and emotions as well as to reduce trait and state anxiety levels. Our study suggests that the presence of a psychologist during the meeting in which a FPP is offered improves communication between doctors and patients, and helps these women to get a full awareness before choosing to join the FPP.

RESUMO

In the last decades, several steps have been made aiming at rendering human IVF more successful on one side, more tolerable on the other side. The "mild" ovarian stimulation approach, in which a lower-than-average dose of exogenous gonadotropins is given and gonadotropin treatment is started from day 2 to 7 of the cycle, represents a significant step toward a more patient's friendly IVF. However, a clear view of its virtues and defects is still lacking, because only a few prospective randomized trials comparing "mild" vs. conventional stimulation exist, and they do not consider some important aspects, such as, e.g., thawing cycles. This review gives a complete panorama of the "mild" stimulation philosophy, showing its advantages vs. conventional ovarian stimulation, but also discussing its disadvantages. Both patients with a normal ovarian responsiveness to exogenous gonadotropins and women with a poor ovarian reserve are considered. Overall, we conclude that the level of evidence supporting the use of "mild" stimulation protocols is still rather poor, and further, properly powered prospective studies about "mild" treatment regimens are required.

RESUMO

Modern advances in oncological treatments determined a significant improvement in survival rates for several malignancies. Nevertheless, survivorship and quality of life of cancer survivors may be negatively impaired by metabolic and endocrine side effects related to anticancer treatments, including alterations of pituitary-gonadal axis function. In fact, both medical (chemo- and radiotherapy) and surgical approaches may negatively impact on gonadal function, leading to transient or permanent hypogonadism and infertility. In view of these considerations, fertility preservation (FP) should be a primary concern in all oncological patients who may potentially achieve parenthood, irrespectively from their sex and pubertal status at treatment, and adequate counselling should be provided before undergoing gonadotoxic therapy or gonadectomy. Cryopreservation of gametes, when feasible, represents the mainstay for FP in postpubertal age, while procedures involving storage of tissue specimens or stem cells should still be considered as experimental. Given the complexity of both hormonal and psychological implications in this clinical setting, a multidisciplinary approach is advisable for optimal FP and for early diagnosis and treatment of hypogonadism.

RESUMO

According to enhanced long-term survival rates of these patients, interest in fertility preservation for young women facing gonadotoxic therapies is increasing. Women who carry a mutation in the BRCA1 or BRCA2 gene have a specifically increased lifetime risk of developing breast and tubo-ovarian cancer. Moreover, they are at high risk of undergoing premature infertility due to the medical interventions that are often performed in order to reduce cancer risk or treat an already existing malignancy. Fertility issues are relevant for healthy BRCA mutation carriers, whose family-planning decisions are often influenced by the need of prophylactic bilateral salpingo-oophorectomy at young age. In BRCA mutation carriers who have a breast cancer at young age, the oncostatic treatment is associated with a significant ovarian toxicity linked to chemotherapy as well as to the long lasting hormonotherapy and to the need of delaying pregnancy for several years. Prompt counselling about different fertility preservation options should be offered to all young girls and women at high risk of ovarian insufficiency and infertility. Validated techniques to preserve fertility include oocyte and embryo cryopreservation, while experimental techniques include ovarian suppression with GnRH-analogs during chemotherapy and ovarian tissue cryopreservation. The choice of the best strategy depends on age, type of chemotherapy, partner status, cancer type, time available for fertility preservation intervention and the risk of ovarian metastasis. All available options should be offered and can be performed alone or in combination. A crucial point is to avoid a significant delay to cancer treatment.

RESUMO

Obesity increases the risk of endometrial and ovarian cancer, and oestrogen receptor (ER)-progesterone receptor (PR)-positive postmenopausal breast cancer. A modest positive association between body mass index (BMI) and cervical cancer has also been found. By contrast, an inverse correlation between BMI and premenopausal breast cancer exists. Endogenous sex hormones, insulin resistance/hyperinsulinaemia, adipokines, cytokines and chronic inflammation, among other factors, may be involved in the promotion of cancer in obese patients. Obesity is also associated with an increased risk of cancer recurrence and mortality most likely due to suboptimal treatment and/or co-morbidities. It is recommended that chemotherapy doses be calculated on the actual body weight and that radical surgery be performed as in non-obese patients. The high risk of peri-operative complications may be reduced by optimizing preoperative clinical conditions. As part of cancer prevention, obese women should be encouraged to adopt healthy lifestyles leading to weight loss and to undergo regular cancer screening.

RESUMO

OBJECTIVE: To describe a live birth obtained in Italy after autologous orthotopic transplantation of cryopreserved ovarian cortical tissue. DESIGN: Case report. SETTING: University department of gynecology and obstetrics, reproductive medicine and IVF unit. PATIENT(S): A 29-year-old patient affected by ß-thalassemia (intermedia phenotype) who underwent chemotherapy and bone marrow transplantation at age 21 years, resulting in a complete precocious ovarian failure. INTERVENTION(S): Before being treated with chemotherapy (busulfan, cyclophosphamide, and cyclosporine) for bone marrow transplantation, the patient underwent laparoscopic sampling of ovarian cortical tissue that was frozen and cryopreserved in liquid nitrogen. Eight years later, the ovarian tissue was thawed and grafted during laparoscopy at an orthotopic site. MAIN OUTCOME MEASURE(S): Ultrasound and endocrine monitoring of the postgrafting restoration of ovarian function; conception, pregnancy, and live birth. RESULT(S): Three months after grafting, the decrease of circulating FSH levels and the parallel increase of E(2) levels demonstrated ovarian function restoration, which was confirmed by bidimensional ultrasound and color Doppler examinations. After some ovulatory cycles, the patient spontaneously conceived 16 months after transplantation. After 39 weeks of uneventful gestation, a healthy girl weighing 3,970 g was born. CONCLUSION(S): Autologous grafting of cryopreserved ovarian cortex at an orthotopic site may allow ovarian function restoration, spontaneous conception, and birth of a healthy baby.

RESUMO

Thanks to the progress in oncostatic treatments, young women affected by cancer have a fairly good chance of surviving the disease and leading a normal post-cancer life. Quite often, however, polychemiotherapy and/or radiotherapy can induce ovarian damage and significantly reduce the content of follicles and oocytes inside the ovary, thus predisposing the patient to menstrual disorders, infertility, and precocious menopause. Several techniques have been proposed to preserve fertility in these patients; among them oocyte collection and cryopreservation prior to the oncostatic treatment has been widely applied in the last decade. The proper indications, the permitting conditions, the available hormonal stimulation protocols, as well as the effectiveness and limits of this option will be discussed herein, with a comprehensive and up-to-date review of the two techniques commonly used to cryostore oocytes, the slow-freezing technique and the vitrification technique.

RESUMO

Thanks to the recent advances in reproductive medicine, more and more young women with breast cancer may be offered the possibility of preserving their fertility. Fertility can be endangered by chemotherapy, by treatment duration and by patient's age at diagnosis. The currently available means to preserve a young woman's fertility are pharmacological protection with gonadotrophin-releasing hormone analogues during chemotherapy, and ovarian tissue or oocyte/embryo freezing before treatment. New future venues, including in vitro maturation, will improve the feasibility and efficacy of the fertility preservation methods in breast cancer patients.
