- The International Federation of Gynecology and Obstetrics (FIGO) ovarian cancer staging system includes no sub-stage for lymph nodes (LN) as only distant disease manifestation. We explore the prognostic implication of LN as only stage IV classifier in serous ovarian cancer.This is a nation-wide, population-based study on 551 women with serous stage IV cancers diagnosed between 2009-2014. We compare overall survival (OS) in women with LN as only distant metastatic site to those with pleural metastases only and to patients with other/multiple stage IV manifestations. Cox regression models were used for uni- and multivariable estimations.Of 551stage IV cases, distant metastatic site was registered in 433. Median OS for women with LN (n=51) was 41.4 months, compared to 25.2 and 26.8 months for patients with pleural (n=195) or other/multiple (n=187) distant metastases (p=.0007). The corresponding five-year survival rates were 32, 11 and 22%, respectively. Multivariable analyzes confirmed shorter survival for women with pleural (HR 2.99, p=.001) or other/multiple distant sites (HR 2.67, p=.007), as compared to LN cases. LN only patients lived 9.1 months longer after primary than after interval surgery, but this difference was not significant (p=.245).Women with stage IV serous ovarian cancer having lymph nodes as only distant metastatic site live longer than other stage IV patients.

- STUDY QUESTION: Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? SUMMARY ANSWER: Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. WHAT IS KNOWN ALREADY: UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 female baboons as uterus recipients. The follow-up time was 5-8 weeks. PARTICIPANTS/MATERIALS, SETTINGAND METHODS: Uterus retrieval was performed with extended hysterectomy including bilateral uterine and internal iliac arteries and ovarian veins. After UTx, with vascular anastomoses unilateral to the internal iliac artery and the external iliac vein, the uterus recipients received one of the following: no immunosuppression (n = 4); monotherapy (oral slow release tacrolimus) (n = 4) or induction therapy (antithymocyte globulin) followed by triple therapy (tacrolimus, mycophenolate, corticosteroids; n = 10). Surgical parameters, survival, immunosuppression and rejection patterns were evaluated. MAIN RESULTS AND THE ROLE OF CHANCE: The durations of uterus retrieval and recipient surgery were around 3 and 3.5 h, respectively. The total ischemic time was around 3 h. All the recipients and the donors survived the surgery. All the recipients presented rejection to some extent within the first weeks following UTx. In one recipient, the uterus was of normal appearance at the end of the study period. In spite of occasional high (>60 ng/ml) blood levels of tacrolimus, there was no evidence of nephrotoxicity. LIMITATIONS AND REASONS FOR CAUTION: This initial non-human primate allogeneic UTx study indicates that further research is needed to optimize immunosuppression protocols in order to avoid uterine rejection. WIDER IMPLICATIONS OF THE FINDINGS: The findings suggest that allogeneic UTx in primate species is feasible but continued work on this issue is needed. STUDY FUNDING/COMPETING INTEREST(S): The study was funded by the Swedish Research Council, ALF University of Gothenburg, Hjalmar Svensson Foundation and by Jane and Dan Olsson Research Foundation. The authors do not have any competing interest.

- The only untreatable subgroup of female infertility is absolute uterine factor infertility (AUFI), which is due to congenital or surgical absence of a uterus or presence of a nonfunctional uterus. The solitary option for a woman with AUFI to become a biological mother today is through a gestational surrogate mother, a procedure that is prohibited in Sweden and large parts of the world. Uterus transplantation (UTx) is a potential future treatment of AUFI. After extensive animal research, also involving non-human primates, a small number of human UTx cases have recently been performed. Here, we summarize the primate UTx experiments that have paved the way for the human UTx cases, which are described and analyzed in more detail. We also estimate how many women of fertile age are affected by AUFI and describe the causes. The ethics around UTx is complex and is also addressed.

- BACKGROUND Uterus transplantation (UTx) may provide the first available treatment for women affected by uterine infertility. The present study aimed to further develop a surgical technique for autologous UTx in a non-human primate species and to assess long-term function. METHODS Female baboons (n= 16) underwent autologous transplantation of the uterus with the Fallopian tubes and ovaries, performed with a previously published surgical technique (n= 6, Group 1) or using a modified technique (n= 10; Group 2). The uterine arteries were dissected to the proximal end of the anterior branch (Group 1) or the entire (Group 2) internal iliac artery, and the ovarian veins were dissected to the crossing over the ureter (Group 1) or further cranially to include greater lengths and patches of the cava/renal vein (Group 2). Back-table preparation created common venous and arterial ends with arterial anastomosis either end-to-side to the left external iliac artery (Group 1) or end-to-end to the left internal iliac artery (Group 2). RESULTS Overall short-time survival of the animals was 88% (66% in Group 1 and 100% in Group 2). Of all the operated animals, 75% (66% in Group 1 and 80% in Group 2) resumed ovarian cyclicity. Regular menstruation after UTx was demonstrated only in Group 2 (60%). Menstruating animals (n= 6) were each exposed to timed mating for ≥5 menstrual cycles, but pregnancy did not occur. Adhesions and tubal blockage were seen in post-mortem analysis. CONCLUSIONS The modified UTx model of Group 2 is a safe procedure and shows resumed long-term uterine function in a majority of the animals, although pregnancy could not be demonstrated.

- Background: Epithelial ovarian cancer (EOC) is rare in women of reproductive age and fertility-sparing surgery (FSS) may be applied in early stages. The purpose of this study was to investigate the safety and efficacy of FSS for treatment of EOC. Methods: The Swedish nationwide population-based Quality Register for Gynecological Cancer was used to identify all women 18–40 years of age diagnosed with stage I EOC between 2008 and 2015. Detailed data on surgery, staging, histopathology, and follow-up were extracted and reviewed. Cross-linking of individuals to population-based registries allowed retrieval of data on obstetrical and reproductive outcomes after FSS. Disease-free survival (DFS) and overall survival (OS) rates were compared (Kaplan-Meier method) between women who underwent FSS vs. radical surgery (RS). Results: In total 83 women were identified; 36 who had FSS performed and 47 RS. The 5-year OS rate was 92% and no statistical differences between DFS or OS were found between women treated by FSS or RS. The recurrence rate after RS was 13% compared to 6% after FSS. Recurrences were more frequently found in women with stage IC tumor or with histologic subtypes with more aggressive behavior. In the FSS cohort, nine women gave birth to 12 healthy children, all delivered at fullterm. Only one women had received assisted reproductive technology treatment. Conclusion: In this nationwide population-based cohort study natural fertility was maintained after FSS. Specific histologic subtypes showed greater prognostic impact on the oncological outcome than the use of FSS. Recurrences occurred after FSS, but none in the uterus, which questions the need of hysterectomy in young women with EOC. Trial registration: This article reports the results of a healthcare intervention using the data prospectively registered in the Swedish population-based registries including the Quality Register for Gynecological Cancer, the National Death Register, the Swedish Medical Birth Register, and the National Quality Register for Assisted Reproduction. © 2020, The Author(s).

- Objective: To compare the oncologic outcome of women who underwent fertility-sparing surgery (FSS) vs. radical surgery (RS) for treatment of NEOC in a prospective, nationwide, population-based study and report on the reproductive outcomes in women after FSS. Methods: Using the Swedish Quality Register for Gynecological Cancer, we identified all women ages 18–40 treated with either FSS or RS for stage I NEOC between 2008 and 2015. Progression-free survival (PFS) and overall survival (OS) rates were compared using the Kaplan-Meier method. Data on use of assisted reproductive technology (ART) treatments and obstetrical outcomes after FSS were extracted from the National Quality Register for Assisted Reproduction (Q-IVF) and the Swedish Medical Birth Register. Results: During the study period, 73 women ages 18–40 received a stage I NEOC diagnosis. The majority, 78% (n = 57), underwent FSS. The 5-year OS rate, regardless of surgical approach, was 98%. There were no statistical differences between OS and PFS rates in women treated with FSS, compared to RS. Recurrences were more common after RS than FSS: 12.5% (2/16) vs. 3.5% (2/57), respectively. Following FSS, 11 women gave birth to 13 healthy children (all conceived naturally). Additionally, 12% of the women in the cohort developed infertility and received ART treatment (n = 7). Conclusion: FSS is not associated with worse oncologic outcomes than RS in young women with early stage NEOC. The prognosis was excellent in both groups, with an OS of 98%. Natural fertility was maintained in women treated with FSS, only 12% required ART treatment. © 2019

- Objective. This study aimed to investigate health-related quality of life (HRQoL), sexual function, psychological- health, reproductive concerns, and fertility outcomes of women of reproductive age undergoing Fertility-Sparing Surgery (FSS) for treatment of ovarian cancer (OC) or borderline ovarian tumor (BOT), over a 2-year period. Methods. Prospective longitudinal multicentre study including women 18-40 years undergoing FSS between 2016 and 2018 in Sweden. Clinical data at diagnosis, histopathological findings and 2-year follow-up regarding oncological and reproductive outcomes were collected. Participants completed the EORTC QLQ-C30 and OV-28, FSFI, HADS and study-specific items at time of diagnosis and at one- and two-years following FSS. Data were analysed using a model for repeated measures to investigate changes over time. Results. Of 68 eligible women, 49 were included following exclusions due to benign pathology or subsequent radical surgery. During a mean follow-up of 20.5 months, two women experienced a recurrence and 82% reported regular menstruations. The majority (94%) had a strong desire to become biological mothers, which remained or increased over time. The conception-rate was 76%. HRQoL, psychological-health and sexual function improved over time and the proportion of women with sexual dysfunction decreased. At one-year follow-up 50% of nulliparous women had scores indicating sexual dysfunction compared to 0% of the women who had given birth either before or after surgery (p = 0.008). Conclusion. HRQoL, psychological-health and sexual function improved during two-year follow-up after FSS in young women presenting with OC or BOT. Women who had given birth prior to or after FSS reported improved sexual function compared to nulliparous women. (c) 2024 The Authors. Published by Elsevier Inc.

- Objective: To assess the efficacy of fertility-sparing surgery (FSS) in terms of reproductive outcomes by following FSS for borderline ovarian tumors (BOTs) and comparing the safety of FSS versus radical surgery (RS). Design: Nationwide cohort study based on prospectively recorded data. Setting: Sweden. Patient (s): All women of reproductive age (18–40 years) treated in Sweden for stage I BOT with the use of FSS or RS from 2008 to 2015, identified in the Swedish Quality Registry for Gynecologic Cancer (SQRGC). Interventions (s): FSS or RS. Main Outcome Measure (s): Reproductive outcomes: natural conception, use of assisted reproductive technology (ART), live birth and obstetrical outcomes. Safety outcome: overall survival (OS) rates, comparing women undergoing FSS versus RS. The FSS cohort was linked to the Swedish Medical Birth Register to identify all women who had given birth after FSS and to obtain detailed obstetrical data. For information on ART treatment, the National Quality Registry for Assisted Reproduction was consulted. OS rate comparisons were conducted by means of Kaplan-Meier estimates. Result (s): Of the 277 women with BOTs, 213 (77%) underwent FSS, 183 (86%) unilateral salpingo-oophorectomy, and 30 (14%) cystectomy. Following FSS, 50 women gave birth to 62 healthy children, 8% of which were preterm. Only 20 (9%) of the women underwent ART treatment. OS was similar in women treated with FSS and RS. Conclusion (s): Natural fertility was maintained after FSS; only 9% required ART treatment. FSS was also deemed to be equivalent to RS regarding survival outcome. © 2020 The Authors
