A 10-year follow-up of reproductive outcomes in women attempting motherhood after elective oocyte cryopreservation.

STUDY QUESTION: Which reproductive treatment outcomes are observed in women who underwent elective oocyte cryopreservation (EOC) and who returned to the clinic with a desire for a child? SUMMARY ANSWER: Whether to warm oocytes or to first use fresh own oocytes for ART depends on age upon returning, but both strategies result in favorable reproductive outcomes. WHAT IS KNOWN ALREADY: Most affluent countries have observed a trend toward postponement of childbearing, and EOC is increasingly used based on the assumption that oocytes cryopreserved at a younger age may extend a woman's reproductive lifespan and mitigate her age-related fertility decline. Although most follow-up studies after EOC have focused on women who requested oocyte warming, a substantial proportion of women who do not conceive naturally will embark on fertility treatment without using their cryopreserved oocytes. Reports on reproductive outcomes in past EOC users are scarce, and the lack of reproductive treatment algorithms in this group of women hampers counseling toward the most efficient clinical strategy. STUDY DESIGN, SIZE, DURATION: This retrospective observational single-center study encompasses 843 women who had elective oocyte vitrification between 2009 and 2019 at our fertility clinic. Women who underwent fertility preservation for medical or oncological reasons were excluded. This study describes the outcomes of the diverse reproductive treatment strategies performed until May 2022 in women returning to our clinic to attempt motherhood. PARTICIPANTS/MATERIALS, SETTING, METHODS: Using descriptive statistics, patient characteristics and data of ovarian stimulation (OS) of EOC cycles were analyzed, as well as data related to OS and laboratory data of ART in women who pursued fertility treatment with and/or without using their cryopreserved oocytes. The primary outcome was live birth rate (LBR) per patient after oocyte warming and after ART using fresh oocytes. Secondary outcomes were return rate, utilization rate of the cryopreserved oocytes, laboratory outcomes upon return, and LBR per embryo transfer. A multivariable regression model was developed to identify factors associated with the decision to thaw oocytes as the primary strategy and factors associated with ongoing pregnancy upon return to the clinic. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1353 EOC cycles (mean ± SD, 1.6 ± 0.9 per patient) were performed. At the time of EOC, the mean age was 36.5 ± 2.8 years, mean anti-Müllerian hormone (AMH) was 2.3 ± 2.0 ng/ml, and 174 (20.6%) women had a partner. On average, 13.9 ± 9.2 mature oocytes were cryopreserved. Two hundred thirty-one (27.4%) women returned to the clinic, an average of 39.9 ± 23.4 months after EOC. Upon returning, their mean age was 40.4 ± 3.1 years, mean AMH was 1.5 ± 1.5 ng/ml, and 158/231 (68.3%) patients had a partner. As a primary approach, 110/231 (47.6%) past EOC users embarked on oocyte warming, 50/231 (21.6%) had intrauterine insemination, and 71/231 (30.7%) had ART using fresh own oocytes. Cumulative LBR (CLBR) was 45.9% (106/231) notwithstanding a miscarriage rate (MR) of 30.7% (51/166) in the entire cohort. In total, 141 women performed oocyte warming at some stage in their treatment trajectory. A subset of 90/231 (39.0%) patients exclusively had oocyte warming (41.6 ± 3.0 years, with 10.0 ± 5.2 oocytes warmed per patient). 52/231 (22.5%) patients exclusively had ART using fresh own oocytes (mean age of 39.0 ± 2.8 years, with 9.9 ± 7.4 mature oocytes retrieved per patient). CLBR was 37/90 (41.1%) in the oocyte warming-only group and 25/52 (48.1%) in the OS-only group. MR/transfer was 25.0% and 29.3% in the oocyte warming-only group and the OS-only group, respectively. LIMITATIONS, REASONS FOR CAUTION: Both sample size and the retrospective design are limitations of this study. The decision to embark on a specific reproductive treatment strategy was based on patient preference, after counseling on their treatment options. This precludes direct comparison of the efficiency of reproductive treatment options in past EOC users in this study. WIDER IMPLICATIONS OF THE FINDINGS: Reporting on clinical outcomes of women who underwent EOC and returned to the clinic to embark on divergent reproductive treatment strategies is mandatory to establish guidelines for best clinical practice in this growing patient population.

Clinical outcomes from ART in predicted hyperresponders: in vitro maturation of oocytes versus conventional ovarian stimulation for IVF/ICSI.

STUDY QUESTION: Do ongoing pregnancy rates (OPRs) differ in predicted hyperresponders undergoing ART after IVM of oocytes compared with conventional ovarian stimulation (OS) for IVF/ICSI? SUMMARY ANSWER: One cycle of IVM is non-inferior to one cycle of OS in women with serum anti-Müllerian hormone (AMH) levels ≥10 ng/ml. WHAT IS KNOWN ALREADY: Women with high antral follicle count and elevated serum AMH levels, indicating an increased functional ovarian reserve, are prone to hyperresponse during ART treatment. To avoid iatrogenic complications of OS, IVM has been proposed as a mild-approach alternative treatment in predicted hyperresponders, including women with polycystic ovary syndrome (PCOS) who are eligible for ART. To date, inferior pregnancy rates from IVM compared to OS have hampered the uptake of IVM by ART clinics. However, it is unclear whether the efficiency gap between IVM and OS may differ depending on the extent of AMH elevation. STUDY DESIGN, SIZE, DURATION: This study is a retrospective cohort analysis of clinical and laboratory data from the first completed highly purified hMG (HP-hMG) primed, non-hCG-triggered IVM or OS (FSH or HP-hMG stimulation in a GnRH antagonist protocol) cycle with ICSI in predicted hyperresponders ≤36 years of age at a tertiary referral university hospital. A total of 1707 cycles were included between January 2016 and June 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Predicted hyperresponse was defined as a serum AMH level ≥3.25 ng/ml (Elecsys® AMH, Roche Diagnostics). The primary outcome was cumulative ongoing pregnancy rate assessed 10-11 weeks after embryo transfer (ET). The predefined non-inferiority limit was -10.0%. The analysis was adjusted for AMH strata. Time-to-pregnancy, defined as the number of ET cycles until ongoing pregnancy was achieved, was a secondary outcome. Statistical analysis was performed using a multivariable regression model controlling for potential confounders. MAIN RESULTS AND THE ROLE OF CHANCE: Data from 463 IVM cycles were compared with those from 1244 OS cycles. Women in the IVM group more often had a diagnosis of Rotterdam PCOS (434/463, 93.7%) compared to those undergoing OS (522/1193, 43.8%), were significantly younger (29.5 years versus 30.5 years, P ≤ 0.001), had a higher BMI (25.7 kg/m2 versus 25.1 kg/m2, P ≤ 0.01) and higher AMH (11.6 ng/ml versus 5.3 ng/ml, P ≤ 0.001). Although IVM cycles yielded more cumulus-oocyte complexes (COCs) (24.5 versus 15.0 COC, P ≤ 0.001), both groups had similar numbers of mature oocytes (metaphase II (MII)) (11.9 MII versus 10.6 MII, P = 0.9). In the entire cohort, non-adjusted cumulative OPR from IVM was significantly lower (198/463, 42.8%) compared to OS (794/1244, 63.8%), P ≤ 0.001. When analysing OPR across different serum AMH strata, cumulative OPR in both groups converged with increasing serum AMH, and OPR from IVM was non-inferior compared to OS from serum AMH levels >10 ng/ml onwards (113/221, 51.1% (IVM); 29/48, 60.4% (OS)). The number of ETs needed to reach an ongoing pregnancy was comparable in both the IVM and the OS group (1.6 versus 1.5 ET's, P = 0.44). Multivariable regression analysis adjusting for ART type, age, BMI, oocyte number, and PCOS phenotype showed that the number of COCs was the only parameter associated with OPR in predicted hyperresponders with a serum AMH >10 ng/ml. LIMITATIONS, REASONS FOR CAUTION: These data should be interpreted with caution as the retrospective nature of the study holds the possibility of unmeasured confounding factors. WIDER IMPLICATIONS OF THE FINDINGS: Among subfertile women who are eligible for ART, IVM, and OS resulted in comparable reproductive outcomes in a subset of women with a serum AMH ≥10 ng/ml. These findings should be corroborated by a randomised controlled trial (RCT) comparing both treatments in selected patients with elevated AMH.

Does dual oocyte retrieval with continuous FSH administration increase the number of mature oocytes in low responders? An open-label randomized controlled trial.

STUDY QUESTION: Is there an increase in the total number of metaphase II (MII) oocytes between a conventional ovarian stimulation (OS) and a double uninterrupted stimulation? SUMMARY ANSWER: There is no increase in the total number of MII oocytes when comparing one conventional OS to a continuous stimulation with double oocyte aspiration. WHAT IS KNOWN ALREADY: Based on the concept of multiple follicular waves, the combination of two stimulations in the same ovarian cycle has gained interest in patients with a low ovarian reserve. This so-called dual stimulation approach is usually characterized by a discontinuation of FSH administration for ∼5 days and appears to have a favourable impact on the number of retrieved oocytes without affecting the embryo quality or ploidy status. The outcomes of dual uninterrupted OS have not yet been studied. STUDY DESIGN, SIZE, DURATION: This was an open-label randomized controlled trial (RCT) with superiority design, performed in a single tertiary centre. Subjects were randomized with a 1:1 allocation into two groups between October 2019 and September 2021. All patients underwent a conventional stimulation with recombinant FSH. When two or more follicles of 17 mm were present, the final inclusion criterion was assessed; randomization occurred only in the presence of ≤9 follicles of ≥11 mm. In Group A, ovulation was triggered with hCG, and oocyte retrieval (OR) was performed 34-36 h later, followed by a fresh single or double embryo transfer (SET or DET) on Day 3/5. In Group B, ovulation was triggered with GnRH agonist, followed by another OS, without discontinuation of the FSH administration. In the presence of one or more follicles of ≥17 mm, the second stimulation was completed with hCG. A freeze-all strategy (Day 3/5) was applied for both retrievals, followed by transfer of one or two embryos in an artificially prepared frozen-thawed cycle. In the absence of one or more follicles of ≥17 mm after 13 additional days of stimulation, the second cycle was cancelled. All ORs were executed by a senior fertility specialist who was blinded for the first treatment, and all follicles >10 mm were aspirated, according to routine clinical practice. The primary outcome was the total number of MII oocytes. Patients were followed up until all embryos were transferred, or until live birth was achieved. Other secondary outcomes included the number of cumulus-oocyte complexes (COCs), the number of good quality embryos (Day 3/5), the ongoing pregnancy rate, and gonadotropin consumption. PARTICIPANTS/MATERIALS, SETTING, METHODS: Patients between 25 and 40 years old, with an anti-Müllerian hormone level of ≤1.5 ng/ml, antral follicle count of ≤6, or ≤5 oocytes after a previous stimulation, were included. At the start, 70 patients were eligible for participation in the trial, of whom 48 patients fulfilled the final inclusion criterium and were randomized. After drop-out of two patients, 23 patients were randomized to a single round of OS (Group A), and 23 patients were randomized to two uninterrupted rounds of OS (Group B). MAIN RESULTS AND THE ROLE OF CHANCE: Baseline characteristics were similar between both groups. The cumulative number of COCs and MII oocytes after completion of the second OR was similar in Group A and Group B [5.3 ± 2.7 versus 5.3 ± 3.0 (P = 0.95); 4.1 ± 2.4 versus 4.3 ± 2.7 (P = 0.77)]. Likewise, a comparable number of excellent and good quality embryos was available on Day 3 (3.0 ± 2.0 versus 2.7 ± 2.0; P = 0.63). In Group B, the cancellation rate due to insufficient response to the second round of stimulation was 39.1% (9/23). When focusing on the first stimulation in both groups, there were no significant differences regarding basal FSH, gonadotropin consumption, and the number of preovulatory follicles. After the first OR, the mean number of COC and MII oocytes was significantly higher in Group A (who had hCG triggering), compared to Group B (who had GnRH agonist triggering) [5.3 ± 2.7 versus 3.3 ± 2.2; difference 95% CI (0.54 to 3.45), P = 0.004 and 4.1 ± 2.4 versus 3.0 ± 2.2; difference 95% CI (-0.15 to 2.6), P = 0.05, respectively]. Likewise, the number of excellent and good quality embryos on Day 3 was significantly higher (3.0 ± 2.0 versus 1.9 ± 1.7; P = 0.02) in Group A. LIMITATIONS, REASONS FOR CAUTION: This study was powered to demonstrate superiority for the number of MII oocytes after dual stimulation. Investigating the impact of dual stimulation on pregnancy rates would have required a larger sample size. Furthermore, the heterogeneity in embryo vitrification and transfer policies precluded a correct comparison of embryologic outcomes between both groups. WIDER IMPLICATIONS OF THE FINDINGS: This is the first RCT investigating the role of continuous stimulation with double aspiration in low responders. Our results show no statistically significant differences in the cumulative number of MII oocytes between one conventional stimulation with fresh ET and two consecutive stimulations with a freeze-only approach. Furthermore, the observed suboptimal oocyte yield after agonist ovulation triggering in low responders in the dual uninterrupted OS group is a reason for concern and further scrutiny, given that previous RCTs have shown similar outcomes in normal and high responders after hCG and GnRH agonist triggers.

Effect of reduced follow-up care on patient satisfaction with care among patients with endometrial cancer: The ENSURE randomized controlled trial.

BACKGROUND: Evidence on the optimal follow-up schedule after endometrial cancer is lacking. The study aim was to compare satisfaction with care between women who received reduced follow-up care and women who received usual guideline-directed follow-up care for three years after surgery. METHODS: The ENSURE (ENdometrial cancer SURvivors' follow-up carE) trial was a non-inferiority randomized controlled multicenter trial in 42 hospitals in the Netherlands. The intervention arm received reduced follow-up care (4 visits/3 years), while the control group received usual follow-up care (8-11 visits/3 years). Primary outcome was overall satisfaction with care, PSQIII score, over three years follow-up, with a non-inferiority margin of 6. Mixed linear regression, intention-to-treat and per-protocol analyses (presented below) were used. RESULTS: Among 316 women included, overall satisfaction with care was not lower in the reduced follow-up (mean 82; SD = 15) compared with the usual follow-up group (mean 80; SD = 15) group (B = 1.80(-2.09;5.68)). At 6, 12 and 36 months, more women (93/94/90%) in the reduced follow-up group were satisfied with their follow-up schedule than in the usual follow-up group (79/79/82%; p < 0.001; p < 0.001; p = 0.050). CONCLUSIONS AND RELEVANCE: Women with low-risk, early-stage endometrial cancer who received reduced follow-up care were no less satisfied with their care than women receiving usual follow-up care. Compared with usual follow-up, women in the reduced follow-up group had fewer clinical visits and, at the same time, more often reported being satisfied with their follow-up schedule. Findings suggest that reduced follow-up care may be the new standard, but should be tailored to meet additional needs where indicated.

Progestin primed ovarian stimulation using dydrogesterone from day 7 of the cycle onwards in oocyte donation cycles: a longitudinal study.

RESEARCH QUESTION: Does a progestin-primed ovarian stimulation (PPOS) protocol with dydrogesterone from cycle day 7 yield similar outcomes compared with a gonadotrophin-releasing hormone (GnRH) antagonist protocol in the same oocyte donors? DESIGN: This retrospective longitudinal study included 128 cycles from 64 oocyte donors. All oocyte donors had the same type of gonadotrophin and daily dose in both stimulation cycles. The primary outcome was the number of cumulus-oocyte complexes (COC) retrieved. RESULTS: The number of COC retrieved (mean ± SD 19.7 ± 10.8 versus 19.2 ± 8.3; P = 0.5) and the number of metaphase II oocytes (15.5 ± 8.4 versus 16.2 ± 7.0; P = 0.19) were similar for the PPOS and GnRH antagonist protocols, respectively. The duration of stimulation (10.5 ± 1.5 days versus 10.8 ± 1.5 days; P = 0.14) and consumption of gonadotrophins (2271.9 ± 429.7 IU versus 2321.5 ± 403.4 IU; P = 0.2) were also comparable, without any cases of premature ovulation. Nevertheless, there was a significant difference in the total cost of medication per cycle: €898.3 ± 169.9 for the PPOS protocol versus €1196.4 ± 207.5 (P < 0.001) for the GnRH antagonist protocol. CONCLUSION: The number of oocytes retrieved and number of metaphase II oocytes were comparable in both stimulation protocols, with the advantage of significant cost reduction in favour of the PPOS protocol compared with the GnRH antagonist protocol. No cases of premature ovulation were observed, even when progestin was started later in the stimulation.

Reproductive outcomes in women opting for fertility preservation after fertility-sparing surgery for borderline ovarian tumors.

PURPOSE: What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)? METHODS: A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth. RESULTS: In total, thirteen patients who performed 31 FP cycles were included. Of those, six patients achieved eight live births after a mean follow-up period of 79 months. Three further pregnancies are still ongoing. All pregnancies/live births were obtained without using their cryopreserved oocytes or embryos. CONCLUSION: Women who had FSS for BOT have favorable prospects of live offspring, even without the need to use their cryopreserved material. Fertility preservation in patients with BOT has to be considered as a tool to mitigate the risk of infertility that may arise in case of BOT recurrence requiring castrating surgery.

Functional estrogen receptor signal transduction pathway activity and antihormonal therapy response in low-grade ovarian carcinoma.

BACKGROUND: Advanced low-grade ovarian carcinoma (LGOC) is difficult to treat. In several studies, high estrogen receptor (ER) protein expression was observed in patients with LGOC, which suggests that antihormonal therapy (AHT) is a treatment option. However, only a subgroup of patients respond to AHT, and this response cannot be adequately predicted by currently used immunohistochemistry (IHC). A possible explanation is that IHC only takes the ligand, but not the activity, of the whole signal transduction pathway (STP) into account. Therefore, in this study, the authors assessed whether functional STP activity can be an alternative tool to predict response to AHT in LGOC. METHODS: Tumor tissue samples were obtained from patients with primary or recurrent LGOC who subsequently received AHT. Histoscores of ER and progesterone receptor (PR) were determined. In addition, STP activity of the ER STP and of six other STPs known to play a role in ovarian cancer was assessed and compared with the STP activity of healthy postmenopausal fallopian tube epithelium. RESULTS: Patients who had normal ER STP activity had a progression-free survival (PFS) of 16.1 months. This was significantly shorter in patients who had low and very high ER STP activity, with a median PFS of 6.0 and 2.1 months, respectively (p < .001). Unlike ER histoscores, PR histoscores were strongly correlated to the ER STP activity and thus to PFS. CONCLUSIONS: Aberrant low and very high functional ER STP activity and low PR histoscores in patients with LGOC indicate decreased response to AHT. ER IHC is not representative of functional ER STP activity and is not related to PFS.

To Test or Not? Xpert MTB/RIF as an Alternative to Smear Microscopy to Guide Line Probe Assay Testing for Drug-Resistant Tuberculosis.

Xpert MTB/RIF (Xpert) revolutionized tuberculosis (TB) diagnosis. Laboratory decision making on whether widely-used reflex drug susceptibility assays (MTBDRplus, first-line resistance; MTBDRsl, second-line) are conducted is based on smear status, with smear-negative specimens often excluded. We performed receiver operator characteristic (ROC) curve analyses using bacterial load information (smear microscopy grade, Xpert-generated semi-quantitation categories and minimum cycle threshold [CTmin] values) from Xpert rifampicin-resistant sputum for the prediction of downstream line probe assay results as "likely non-actionable" (no resistance or susceptible results generated). We evaluated actionable-to-non-actionable result ratios and pay-offs with missed resistance versus LPAs done universally. Smear-negatives were more likely than smear-positive specimens to generate a non-actionable MTBDRplus (23% [133/559] versus 4% [15/381]) or MTBDRsl (39% [220/559] versus 12% [47/381]) result. However, excluding smear-negatives would result in missed rapid diagnoses (e.g., only 49% [264/537] of LPA-diagnosable isoniazid resistance would be detected if smear-negatives were omitted). Testing smear-negatives with a semi-quantitation category ≥ "medium" had a high ratio of actionable-to-non-actionable results (12.8 or a 4-fold improvement versus testing all using MTBDRplus, 4.5 or 3-fold improvement for MTBDRsl), which would still capture 64% (168/264) and 77% (34/44) of LPA-detectable smear-negative resistance, respectively. Use of CTmins permitted optimization of this ratio with higher specificity for non-actionable results but decreased resistance detected. Xpert quantitative information permits identification of a smear-negative subset in whom the payoffs of the ratio of actionable-to-non-actionable LPA results with missed resistance may prove acceptable to laboratories, depending on context. Our findings permit the rational expansion of direct DST to certain smear-negative sputum specimens.

SAFESTEREO: phase II randomized trial to compare stereotactic radiosurgery with fractionated stereotactic radiosurgery for brain metastases.

BACKGROUND: Stereotactic radiosurgery (SRS) is a frequently chosen treatment for patients with brain metastases and the number of long-term survivors is increasing. Brain necrosis (e.g. radionecrosis) is the most important long-term side effect of the treatment. Retrospective studies show a lower risk of radionecrosis and local tumor recurrence after fractionated stereotactic radiosurgery (fSRS, e.g. five fractions) compared with stereotactic radiosurgery in one or three fractions. This is especially true for patients with large brain metastases. As such, the 2022 ASTRO guideline of radiotherapy for brain metastases recommends more research to fSRS to reduce the risk of radionecrosis. This multicenter prospective randomized study aims to determine whether the incidence of adverse local events (either local failure or radionecrosis) can be reduced using fSRS versus SRS in one or three fractions in patients with brain metastases. METHODS: Patients are eligible with one or more brain metastases from a solid primary tumor, age of 18 years or older, and a Karnofsky Performance Status ≥ 70. Exclusion criteria include patients with small cell lung cancer, germinoma or lymphoma, leptomeningeal metastases, a contraindication for MRI, prior inclusion in this study, prior surgery for brain metastases, prior radiotherapy for the same brain metastases (in-field re-irradiation). Participants will be randomized between SRS with a dose of 15-24 Gy in 1 or 3 fractions (standard arm) or fSRS 35 Gy in five fractions (experimental arm). The primary endpoint is the incidence of a local adverse event (local tumor failure or radionecrosis identified on MRI scans) at two years after treatment. Secondary endpoints are salvage treatment and the use of corticosteroids, bevacizumab, or antiepileptic drugs, survival, distant brain recurrences, toxicity, and quality of life. DISCUSSION: Currently, limiting the risk of adverse events such as radionecrosis is a major challenge in the treatment of brain metastases. fSRS potentially reduces this risk of radionecrosis and local tumor failure.

A web-based decision aid for shared decision making in pelvic organ prolapse: the SHADE-POP trial.

INTRODUCTION AND HYPOTHESIS: Among women worldwide, pelvic organ prolapse (POP) is a common problem. There are three different treatment options for POP: pelvic floor muscle therapy, pessary treatment and prolapse surgery. As none of the three treatment options is clearly superior, shared decision making (SDM) is very important. A decision aid (DA) is known to facilitate patient participation and SDM. We hypothesise that the use of a web-based DA for POP increases patients' satisfaction with information and care and reduces decisional conflict. METHODS: This two-arm, multicentre, cluster randomised controlled trial was performed in women with POP in five different Dutch hospitals. The control group received usual care (UC) and the intervention group received the DA in addition to UC. Primary outcome measures were satisfaction with treatment decision making and satisfaction with information. Analyses were performed using independent sample t tests, Chi-squared tests, and multilevel linear regression analyses. RESULTS: Between the DA group (n=40) and the UC group (n=56) no differences were found concerning patients' satisfaction with information, with scores of 45.63 and 46.14 out of 50 respectively (p=0.67). Also, no differences were found concerning the perceived role in decision making, as patients scored 46.83 in the DA group and 46.41 in the UC group, out of a maximum of 54 (n=0.81). CONCLUSIONS: No differences were found concerning patients' satisfaction with information and treatment decision making between the DA and UC. However, both groups scored high on the questionnaires, which suggests that the decision process is already of high quality.

Patient characteristics and factors contributing to recurrence of bacterial vaginosis presented in primary care.

BACKGROUND: Bacterial vaginosis (BV) is a common problem in primary care. BV symptoms often have a negative impact on patients' quality of life and may predispose to gynaecological problems. Some patients experience recurring episodes of BV. This study's objective is to identify possible factors that may be associated with BV recurrence and describe the characteristics of these patients and interventions performed by general practitioners. METHODS: In this retrospective cohort study, we used data from a primary care registration network in the Netherlands in the period 2015-2020. We analysed differences between patients with recurrent BV and patients with a single episode of BV in terms of characteristics and interventions performed by general practitioners. RESULTS: We found that patients with recently prescribed antibiotics, and a medical history of sexually transmitted infections and/or Candidiasis significantly more often presented with recurrent BV. Patients with recurrent BV had more remote consultations and less in-person consultations than single-episode patients. The reason for encounter was more often a request for medication. Regarding GPs' diagnostic and therapeutic interventions, microbiological tests were more frequently performed in recurrent BV patients. Moreover, most patients in both groups were prescribed oral metronidazole most frequently. CONCLUSIONS: Our findings might help GPs to better recognise patients at risk of recurrence. GPs could re-evaluate their approach to the diagnosis and treatment of recurrent BV, opting for in-person consultation and using standardised diagnostic criteria and microbiological testing in patients with recurrent complaints. Antibiotic use for other conditions in these patients may lead to new BV episodes.

Cancer-related psychosocial factors and self-reported changes in lifestyle among gynecological cancer survivors: cross-sectional analysis of PROFILES registry data.

PURPOSE: Obesity is prevalent in gynecological cancer survivors and is associated with impaired health outcomes. Concerns due to cancer and its treatment may impact changes in lifestyle after cancer. This study aimed to assess the association between cancer-related psychosocial factors and changes in physical activity and diet, 18 months after initial treatment among gynecological cancer survivors. METHODS: Cross-sectional data from the ROGY Care study were used, including endometrial and ovarian cancer patients treated with curative intent. The Impact of Cancer Scale (IOCv2) was used to assess cancer-related psychosocial factors. Self-reported changes in nutrients/food groups and in physical activity post-diagnosis were classified into change groups (less/equal/more). Multivariable logistic regression models were used to assess associations. RESULTS: Data from 229 cancer survivors (59% endometrial, 41% ovarian, mean age 66 ± 9.5, 70% tumor stage I) were analyzed. In total, 20% reported to eat healthier from diagnosis up to 18 months after initial treatment, 17% reported less physical activity and 20% more physical activity. Health awareness (OR 2.79, 95% CI: 1.38; 5.65), body change concerns (OR 3.04 95% CI: 1.71; 5.39), life interferences (OR 4.88 95% 2.29; 10.38) and worry (OR 2.62, 95% CI: 1.42; 4.85) were significantly associated with less physical activity up to 18 months after initial treatment whereby gastrointestinal symptoms were an important confounder. CONCLUSION(S): This study underlines the need to raise awareness of the benefits of a healthy lifestyle and to provide tailored lifestyle advice, taking into account survivors' health awareness, body change concerns, life interferences, worry and gastrointestinal symptoms, in order to improve health behavior among gynecological cancer survivors.

Cancer worry among BRCA1/2 pathogenic variant carriers choosing surgery to prevent tubal/ovarian cancer: course over time and associated factors.

OBJECTIVE: High cancer risks, as applicable to BRCA1 and BRCA2 pathogenic variant (PV) carriers, can induce significant cancer concerns. We examined the degree of cancer worry and the course of this worry among BRCA1/2-PV carriers undergoing surgery to prevent ovarian cancer, and identified factors associated with high cancer worry. METHODS: Cancer worry was evaluated as part of the multicentre, prospective TUBA-study (NCT02321228) in which BRCA1/2-PV carriers choose either novel risk-reducing salpingectomy with delayed oophorectomy or standard risk-reducing salpingo-oophorectomy. The Cancer Worry Scale was obtained before and 3 and 12 months after surgery. Cancer worry patterns were analysed using latent class growth analysis and associated factors were identified with regression analysis. RESULTS: Of all 577 BRCA1/2-PV carriers, 320 (57%) had high (≥ 14) cancer worry pre-surgery, and 54% had lower worry 12 months post-surgery than pre-surgery. Based on patterns over time, BRCA1/2-PV carriers could be classified into three groups: persistently low cancer worry (56%), persistently high cancer worry (6%), and fluctuating, mostly declining, cancer worry (37%). Factors associated with persistently high cancer concerns were age below 35 (BRCA1) or 40 (BRCA2), unemployment, previous breast cancer, lower education and a more recent BRCA1/2-PV diagnosis. CONCLUSIONS: Some degree of cancer worry is considered normal, and most BRCA1/2-PV carriers have declining cancer worry after gynaecological risk-reducing surgery. However, a subset of these BRCA1/2-PV carriers has persisting major cancer concerns up to 1 year after surgery. They should be identified and potentially offered additional support. CLINICAL TRIAL REGISTRATION: The TUBA-study is registered at ClinicalTrials.gov since December 11th, 2014. Registration number: NCT02321228.

Diagnostic accuracy of mutational analysis along the Müllerian tract to detect ovarian cancer.

OBJECTIVE: Ovarian cancer is known for its poor prognosis, which is mainly due to the lack of early symptoms and adequate screening options. In this study we evaluated whether mutational analysis in cervicovaginal and endometrial samples could assist in the detection of ovarian cancer. METHODS: In this prospective multicenter study, we included patients surgically treated for either (suspicion of) ovarian cancer or for a benign gynecological condition (control group). A cervicovaginal self-sample, a Papanicolaou (Pap) smear, a pipelle endometrial biopsy, and the surgical specimen were analyzed for (potentially) pathogenic variants in eight genes (ARID1A, CTNNB1, KRAS, MTOR, PIK3CA, POLE, PTEN, and TP53) using single-molecule molecular inversion probes. Sensitivity and specificity were calculated to assess diagnostic accuracy. RESULTS: Based on surgical histology, our dataset comprised 29 patients with ovarian cancer and 32 controls. In 83% of the patients with ovarian cancer, somatic (potentially) pathogenic variants could be detected in the final surgical specimen, of which 71% included at least a TP53 variant. In 52% of the ovarian cancer patients, such variants could be detected in either the self-sample, Pap smear, or pipelle. The Pap smear yielded the highest diagnostic accuracy with 26% sensitivity (95% CI 10% to 48%). Overall diagnostic accuracy was low and was not improved when including TP53 variants only. CONCLUSIONS: Mutational analysis in cervicovaginal and endometrial samples has limited accuracy in the detection of ovarian cancer. Future research with cytologic samples analyzed on methylation status or the vaginal microbiome may be relevant.

Cyclic activity of signal transduction pathways in fimbrial epithelium of the human fallopian tube.

INTRODUCTION: The local environment of the fallopian tube represents the optimal conditions for reproductive processes. To maintain tissue homeostasis, signal transduction pathways are thought to play a pivotal role. Enhancing our understanding of functional signal transduction pathway activity is important to be able to clarify the role of aberrant signal transduction pathway activity leading to female subfertility and other tubal diseases. Therefore, in this study we investigate the influence of the hormonal cycle on the activity of key signal transduction pathways in the fimbrial epithelium of morphologically normal fallopian tubes. MATERIAL AND METHODS: We included healthy pre- (n = 17) and postmenopausal (n = 8) patients who had surgical interventions for benign gynecologic conditions. Histologic sections of the fallopian tubes were reviewed by two pathologists and, for the premenopausal patients, hormone serum levels and sections of the endometrium were examined to determine the hormonal phase (early follicular [n = 4], late follicular [n = 3], early luteal [n = 5], late luteal [n = 5]). After laser capture microdissection, total mRNA was extracted from the fimbrial epithelium and real-time quantitative reverse transcription-PCR was performed to determine functional signal transduction pathway activity of the androgen receptor (AR), estrogen receptor (ER), phosphoinositide-3-kinase (PI3K), Hedgehog (HH), transforming growth factor-beta (TGF-ß) and canonical wingless-type MMTV integration site (Wnt) pathways. RESULTS: The early luteal phase demonstrated high AR and ER pathway activity in comparison with the late luteal phase (p = 0.016 and p = 0.032, respectively) and low PI3K activity compared with the late follicular phase (p = 0.036), whereas the late luteal phase showed low activity of HH and Wnt compared with the early follicular phase (both p = 0.016). Signal transduction pathway activity in fimbrial epithelium from postmenopausal patients was most similar to the early follicular and/or late luteal phase with regard to the AR, ER and PI3K pathways. Wnt pathway activity in postmenopausal patients was comparable to the late follicular and early luteal phase. We observed no differences in HH and TGF-ß pathway activity between pre- and postmenopausal samples. The cyclic changes in signal transduction pathway activity suggest a stage-specific function which may affect the morphology and physiology of the human fallopian tube. CONCLUSIONS: We demonstrated cyclic changes in activity of the AR, ER, PI3K, HH and Wnt pathways throughout the hormonal cycle.

First live birth after fertility preservation using vitrification of oocytes in a woman with mosaic Turner syndrome.

PURPOSE: To report the case of a young woman diagnosed with Turner syndrome (TS) who achieved a live birth using her own oocytes that had been vitrified for fertility preservation. METHODS: A 25-year-old woman with mosaic (45,X/46,XX) TS was referred for fertility preservation (FP) counseling. Serum anti-Müllerian hormone (AMH) level was normal (6.4 µg/L). In view of the unpredictable rate of follicle loss in TS individuals, she requested FP and underwent two cycles of ovarian stimulation (OS) for oocyte cryopreservation (OoC) using a GnRH antagonist protocol and recombinant follicle stimulating hormone (rFSH), 200-250 IU daily for 8 resp. 12 days. RESULTS: In total, 29 metaphase II oocytes (MII) were vitrified after OS. After conceiving spontaneously and achieving a live birth, she returned to the clinic five years after OoC with a desire for pregnancy using in vitro fertilization (IVF) of her cryopreserved oocytes and preimplantation genetic testing (PGT-A). All 29 MII oocytes were thawed; 23 oocytes survived (79.3%) and were inseminated with partner sperm using intracytoplasmic sperm injection (ICSI). Thirteen oocytes were fertilized resulting in three good quality blastocysts which were vitrified after trophectoderm biopsy for PGT-A using array-CGH. Two blastocysts were found to be euploid. One was thawed and transferred to the uterus using a HRT priming protocol. An uneventful pregnancy occurred. The patient delivered a healthy baby girl weighing 3490 g at 40 weeks of gestation. CONCLUSIONS: We report the first live birth achieved using cryopreserved oocytes in a woman diagnosed with mosaic TS. Cryopreservation of oocytes after ovarian stimulation is a realistic option for FP in selected post menarche individuals with mosaic TS. Whether PGT-A may reduce the risk of pregnancy loss in TS has to be confirmed by further studies.

Installing oncofertility programs for breast cancer in limited versus optimum resource settings: Empirical data from 39 surveyed centers in Repro-Can-OPEN Study Part I & II.

PURPOSE: As a further step to elucidate the actual diverse spectrum of oncofertility practices for breast cancer around the globe, we present and discuss the comparisons of oncofertility practices for breast cancer in limited versus optimum resource settings based on data collected in the Repro-Can-OPEN Study Part I & II. METHODS: We surveyed 39 oncofertility centers including 14 in limited resource settings from Africa, Asia & Latin America (Repro-Can-OPEN Study Part I), and 25 in optimum resource settings from the United States, Europe, Australia and Japan (Repro-Can-OPEN Study Part II). Survey questions covered the availability of fertility preservation and restoration options offered to young female patients with breast cancer as well as the degree of utilization. RESULTS: In the Repro-Can-OPEN Study Part I & II, responses for breast cancer and calculated oncofertility scores showed the following characteristics: (1) higher oncofertility scores in optimum resource settings than in limited resource settings especially for established options, (2) frequent utilization of egg freezing, embryo freezing, ovarian tissue freezing, GnRH analogs, and fractionation of chemo- and radiotherapy, (3) promising utilization of oocyte in vitro maturation (IVM), (4) rare utilization of neoadjuvant cytoprotective pharmacotherapy, artificial ovary, and stem cells reproductive technology as they are still in preclinical or early clinical research settings, (5) recognition that technical and ethical concerns should be considered when offering advanced and innovative oncofertility options. CONCLUSIONS: We presented a plausible oncofertility best practice model to guide oncofertility teams in optimizing care for breast cancer patients in various resource settings.

Parameters of poor prognosis in preimplantation genetic testing for monogenic disorders.

STUDY QUESTION: What is the likelihood of success of a single cycle of preimplantation genetic testing for monogenic disorders (PGT-M), measured as the cumulative live birth rate (CLBR) and based on various patient demographics? SUMMARY ANSWER: For all women aged ≤40 years, the CLBR was at least 10% when the number of oocytes was ≥7 (range 10-30%) or was at least 5% when the number of oocytes was ≥3 (range 5-17%). WHAT IS KNOWN ALREADY: The number of oocytes is significantly associated with the number of embryos for genetic testing and the clinical outcome in PGT-M. Embryos diagnosed as affected or embryos that remain without diagnosis cannot be used for embryo transfer. The size of the group of embryos non-suitable for transfer varies between 25% and 81%, depending on the indication. Thus, PGT-M is more likely to be more severely impacted by suboptimal ovarian response, poor fertilization and suboptimal embryo development than conventional IVF/ICSI schemes without PGT. STUDY DESIGN, SIZE, DURATION: This was a single-centre retrospective comparative cohort study, of cycles between January 2011 and December 2015. A total number of 2265 PGT-M cycles were compared to 2833 conventional ICSI cycles. The principal aim of our study was the identification of the parameters of poor CLBR in couples undergoing PGT-M using multiplex short tandem repeat (STR) markers on blastomere biopsy DNA. The secondary aim was to compare the parameters of poor CLBR of the PGT-M population to those of couples undergoing ICSI without PGT. PARTICIPANTS/MATERIALS, SETTING, METHODS: The baseline characteristics of the PGT-M group were compared to the conventional ICSI group. A multiple regression analysis was applied to account for the following potential confounding factors: female age, number of previous ART cycles, number of oocytes/suitable embryos for transfer and dosage of gonadotrophins used for ovarian stimulation. MAIN RESULTS AND THE ROLE OF CHANCE: The PGT-M group was younger (female age 32.0 vs 34.5 years), had a higher number of previous ART cycles (1.1 vs 0.9 cycles) and used more gonadotrophins (2367 vs 1984 IU). Per cycle, the PGT-M group had more retrieved oocytes (11.8 vs 8.3 oocytes), fewer suitable embryos for transfer (1.7 vs 2.8 embryos) and a lower CLBR (29.4% vs 35.0%). Multiple regression analysis showed that the CLBR in the PGT-M group was significantly influenced by female age, the number of previous ART cycles, the number of oocytes and the dose of ovarian stimulation. In both groups, the predicted CLBR increased with increasing numbers of oocytes and suitable embryos. At least two retrieved oocytes or one embryo per single PGT-M cycle could confer an estimated CLBR above 10%. By assessing female age and the number of retrieved oocytes together, it was shown that for all women aged ≤40 years, the predicted CLBR per single PGT-M cycle was ≥10% when the number of oocytes was ≥7 or was ≥5% when the number of oocytes was ≥3. LIMITATIONS, REASONS FOR CAUTION: Despite the large sample size, the findings are confined by limited confounder adjustment and the lack of specific PGT-M comparators. WIDER IMPLICATIONS OF THE FINDINGS: This study aimed to describe the likelihood of success of PGT-M treatment, measured as CLBR, based on various patient demographics. In a PGT-M program, couples need to be informed of the prognosis more specifically when it is futile. The table of predicted CLBRs presented in this study is a useful tool in counselling PGT-M couples for making reproductive choices. STUDY FUNDING/COMPETING INTEREST(S): No funding was required and there are no competing interests. TRIAL REGISTRATION NUMBER: N/A.

Impact of ARTs on oncological outcomes in young breast cancer survivors.

STUDY QUESTION: What is the risk of recurrence in young breast cancer survivors who undergo ARTs following completion of anticancer treatment? SUMMARY ANSWER: ART in breast cancer survivors does not appear to have a negative impact on disease-free survival. WHAT IS KNOWN ALREADY: In healthy women, fertility treatment does not increase the risk of developing breast cancer. At the time of breast cancer diagnosis and before starting anticancer treatments, several studies have shown the safety of performing ART. However, the safety of ART in breast cancer survivors following completion of anticancer treatment remains under-investigated. In general, breast cancer survivors are counselled to avoid any hormonal treatment but there are limited data available on the effect of short exposure to high oestradiol levels during ART. The largest study in this regard included 25 breast cancer survivors exposed to ART and did not show a detrimental effect of ART on patient survival. Hence, taking into account that pregnancy after breast cancer does not affect cancer prognosis, defining the safety of ART in breast cancer survivors remains a priority. STUDY DESIGN, SIZE, DURATION: We conducted a retrospective multicentric matched cohort study including a cohort of breast cancer survivors who underwent ART (exposed patients) between January 2006 and December 2016. Exposed patients who were eligible for the study were matched according to known breast cancer prognostic factors. Matched breast cancer survivors did not undergo ART (non-exposed patients) and were disease-free for a minimum time that was not less than the time elapsed between breast cancer diagnosis and first ART for the matched ART-exposed patients. PARTICIPANTS/MATERIALS, SETTING, METHODS: Data were retrieved from all survivors who had been diagnosed with breast cancer in eight participating centres at an age of ≤40 years, without metastasis, ongoing pregnancy, pre-existing neoplasia or ovarian failure. ART included ovarian stimulation for IVF/ICSI, clomiphene citrate treatment and hormone replacement therapy for embryo transfer. Data were collected from an oncological database for the selection of breast cancer patients in the non-exposed group. Exposed patients were matched (1:2) for germline BRCA status, tumour stage, anticancer treatment and age, whenever feasible. Matched groups were compared at baseline according to characteristics using conditional logistic regression. Kaplan-Meier curves were constructed to compare time to recurrence between groups, with the time of ART as starting point that has been adjusted in the non-exposed group. The analyses were performed using Stata IC/15.1. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 39 breast cancer patients in the ART group were eligible for the analysis and were matched with 73 controls. There was no statistical difference between the two groups for the presence of BRCA mutation, tumour characteristics, use of (neo)adjuvant chemotherapy and of adjuvant endocrine therapy. Exposed patients were younger than non-exposed patients (mean age 31.8 vs 34.3 years, respectively; P < 0.001). In the ART group, 89.7% were nulliparous at diagnosis compared to 46.6% of controls (P < 0.001). ART was performed at a mean age of 37.1 years old, after a median time of 4.1 years following breast cancer diagnosis (range: 1.5-12.5). Median anti-Müllerian hormone at the time of ART was 0.28 ng/ml (range: 0-4.4) and median serum oestradiol peak level was 696.5 pg/ml (range: 139.7-4130). Median follow-up time from first attempt of ART was 4.6 years (range: 2.4-12.5) in the ART group. Adjusted follow-up time for the non-exposed group was 6.9 years (range: 1.1-16.5 years) (P = 0.004). In the ART group, 59% of patients had a pregnancy after breast cancer compared to 26% in the non-exposed patients (P = 0.001). Breast cancer relapsed in 7.7% versus 20.5% women in the ART and non-exposed groups, respectively (hazard ratio 0.46, 95% CI 0.13-1.62, P = 0.23). Median time to relapse was 1.3 (range: 0.3-2.7) years versus 4.5 (range: 0.4-11.1) years after ART and adjusted time in the ART and non-exposed groups, respectively (P = 0.14). LIMITATIONS, REASONS FOR CAUTION: Although this is the first and largest multicentric study addressing the impact of ART on breast cancer recurrence to provide data on oestrogen exposure, only a small number of patients could be included. This reflects the reluctance of breast cancer survivors and/or oncologists to perform ART, and highlights the need for a prospective data registry to confirm the safety of this approach. This would offer the possibility for these patients, who are at a high risk of infertility, to fully benefit from ART. WIDER IMPLICATIONS OF THE FINDINGS: Although recent studies have proven that pregnancy after breast cancer has no detrimental impact on prognosis, counselling patients about the safety of ART remains challenging. Our study provides reassuring data on the use of ART in breast cancer survivors with favourable prognostic factors, for when natural conception fails.

Evaluation of a patient decision aid for BRCA1/2 pathogenic variant carriers choosing an ovarian cancer prevention strategy.

OBJECTIVE: Risk-reducing surgery is advised to BRCA1/2 pathogenic variant (PV) carriers around the age of 40 years to reduce ovarian cancer risk. In the TUBA-study, a multicenter preference study (NCT02321228), BRCA1/2-PV carriers are offered a choice: the standard strategy of risk-reducing salpingo-oophorectomy or the novel strategy of risk-reducing salpingectomy with delayed oophorectomy. We evaluated feasibility and effectiveness of a patient decision aid for this choice. METHODS: Premenopausal BRCA1/2-PV carriers were counselled for risk-reducing surgical options in the TUBA-study; the first cohort was counselled without and the second cohort with decision aid. Evaluation was performed using digital questionnaires for participating women and their healthcare professionals. Outcome measures included actual choice, feasibility (usage and experiences) and effectiveness (knowledge, cancer worry, decisional conflict, decisional regret and self-estimated influence on decision). RESULTS: 283 women were counselled without and 282 women with decision aid. The novel strategy was chosen less frequently in women without compared with women with decision aid (67% vs 78%, p = 0.004). The decision aid was graded with an 8 out of 10 by both women and professionals, and 78% of the women would recommend this decision aid to others. Users of the decision aid reported increased knowledge about the options and increased insight in personal values. Knowledge on cancer risk, decisional conflict, decisional regret and cancer worry were similar in both cohorts. CONCLUSIONS: The use of the patient decision aid for risk-reducing surgery is feasible, effective and highly appreciated among BRCA1/2-PV carriers facing the decision between salpingo-oophorectomy or salpingectomy with delayed oophorectomy.
