- Before the first live birth following uterus transplantation (UTx) in 2014, the 1–2% of women with an absent or non-functional uterus had no hope of childbearing. With 64 cases of UTx and 34 births reported in the scientific literature, this emerging technology has the potential for translation into mainstream clinical practice. However, limitations currently include donor availability, recipient suitability, surgical challenges regarding success and complications, and recipient management after UTx and during pregnancy. This review considers these challenges and ways to overcome them so that UTx could become part of the reproductive specialist's armamentarium when counselling patients with uterine factor infertility.

- Objective. The aim of the study was to determine survival outcome in patients with serous cancer in the ovary, fallopian tube, peritoneum and of undesignated origin. Methods. Nation-wide population-based study of women 18 years with histologically verified non-uterine serous cancer, included in the Swedish Quality Registry for primary cancer of the ovary, fallopian tube and peritoneum diagnosed 2009-2013. Relative survival (RS) was estimated using the Ederer II method. Simple and multivariable analyses were estimated by Poisson regression models. Results. Of 5627 women identified, 1246 (22%) had borderline tumors and 4381 had malignant tumors. In total, 2359 women had serous cancer; 71% originated in the ovary (OC), 9% in the fallopian tube (FTC), 9% in the peritoneum (PPC) and 11% at an undesignated primary site (UPS). Estimated RS at 5-years was 37%; for FTC 54%, 40% for OC, 34% for PPC and 13% for UPS. In multivariable regression analyses restricted to women who had undergone primary or interval debulldng surgery for OC, FTC and PPC, site of origin was not independently associated with survival. Significant associations with worse survival were found for advanced stages (RR 2.63, P<0.001), moderate (RR 1.90, P<0.047) and poor differentiation (RR 2.20, P<0.009), neoadjuvant chemotherapy (RR1.33, P<0.022), residual tumor (RR 2.65, P<0.001) and platinum single (2.34, P<0.001) compared to platinum combination chemotherapy. Conclusion. Survival was poorer for serous cancer at UPS than for ovarian, fallopian tube and peritoneal cancer. Serous cancer at UPS needs to be addressed when reporting and comparing survival rates of ovarian cancer. (C) 2016 Elsevier Inc. All rights reserved.

- AimsThe aim is to report the results of Australia's first uterus transplantation (UTx). MethodsFollowing long-standing collaboration between the Swedish and Australian teams, Human Research Ethics approval was obtained to perform six UTx procedures in a collaborative multi-site research study (Western Sydney Local District Health 2019/ETH13038), including Royal Hospital for Women, Prince of Wales Hospital, and Westmead Hospital in New Souh Wales. Surgeries were approved in both the live donor (LD) and deceased donor models in collaboration with the inaugural Swedish UTx team. ResultsThis is the first UTx procedure to occur in Australia, involving a mother donating her uterus to her daughter. The total operative time for the donor was 9 h 54 min. Concurrently, recipient surgery was synchronised to minimise graft ischaemic time, and the total operative time for the recipient was 6 h 12 min. Surgery was by laparotomy in the LD and recipient. The total warm ischaemic time of the graft was 1 h 53 min, and the cold ischaemic time was 2 h 17 min (total ischaemic time 4 h 10 min). The patient's first menstruation occurred 33 days after the UTx procedure. ConclusionTwenty-five years of Swedish and Australian collaboration has led to Australia's first successfully performed UTx surgery at The Royal Hospital for Women, Sydney, Australia.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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: 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

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Deep myometrial invasion (≥50%) is a prognostic factor for lymph node metastases and decreased survival in endometrial cancer. There is no consensus regarding which pre/intraoperative diagnostic method should be preferred. Our aim was to explore the pattern of diagnostic methods for myometrial invasion assessment in Sweden and to evaluate differences among magnetic resonance imaging (MRI), transvaginal sonography, frozen section, and gross examination in clinical practice. Material and methods: This is a nationwide historical cohort study; women with endometrial cancer with data on assessment of myometrial invasion and FIGO stage I-III registered in the Swedish Quality Registry for Gynecologic Cancer (SQRGC) between 2017 and 2019 were eligible. Data on age, histology, FIGO stage, method, and results of myometrial invasion assessment, pathology results, and hospital level were collected from the SQRGC. The final assessment by the pathologist was considered the reference standard. Results: In the study population of 1401 women, 32% (n = 448) had myometrial invasion of 50% of more. The methods reported for myometrial invasion assessment were transvaginal sonography in 59%, MRI in 28%, gross examination in 8% and frozen section in 5% of cases. Only minor differences were found for age and FIGO stage when comparing methods applied for myometrial invasion assessment. The sensitivity, specificity, and accuracy to find myometrial invasion of 50% or more with transvaginal sonography were 65.6%, 80.3%, and 75.8%, for MRI they were 76.9%, 71.9%, and 73.8%, for gross examination they were 71.9%, 93.6%, and 87.3%, and for frozen section they were 90.0%, 92.7%, and 92.0%, respectively. Conclusions: In Sweden, the assessment of deep myometrial invasion is most often performed with transvaginal sonography, but the sensitivity is lower than for the other diagnostic methods. In clinical practice, the accuracy is moderate for transvaginal sonography and MRI. © 2021 The Authors.

- Background: Ampullary lesions are rare and can be locally treated either with endoscopic papillectomy or transduodenal surgical ampullectomy. Management of local recurrence after a first-line treatment has been poorly studied. Methods: Patients with a local recurrence of an ampullary lesion initially treated with endoscopic papillectomy or transduodenal surgical ampullectomy were retrospectively included from a multi-institutional database (58 centers) between 2005 and 2018. Results: A total of 103 patients were included, 21 (20.4%) treated with redo endoscopic papillectomy, 14 (13.6%) with transduodenal surgical ampullectomy, and 68 (66%) with pancreaticoduodenectomy. Redo endoscopic papillectomy had low morbidity with 4.8% (n = 1) severe to fatal complications and a R0 rate of 81% (n = 17). Transduodenal surgical ampullectomy and pancreaticoduodenectomy after a first procedure had a higher morbidity with Clavien III and more complications, respectively, 28.6% (n = 4) and 25% (n = 17); R0 resection rates were 85.7% (n = 12) and 92.6% (n = 63), both without statistically significant difference compared to endoscopic papillectomy (P = .1 and 0.2). Pancreaticoduodenectomy had 4.4% (n = 2) mortality. No deaths were registered after transduodenal surgical ampullectomy or endoscopic papillectomy. Recurrences treated with pancreaticoduodenectomy were more likely to be adenocarcinomas (79.4%, n = 54 vs 21.4%, n = 3 for transduodenal surgical ampullectomy and 4.8%, n = 1 for endoscopic papillectomy, P < .0001). Three-year overall survival and disease-free survival were comparable. Conclusion: Endoscopy is appropriate for noninvasive recurrences, with resection rate and survival outcomes comparable to surgery. Surgery applies more to invasive recurrences, with transduodenal surgical ampullectomy rather for carcinoma in situ and early cancers and pancreaticoduodenectomy for more advanced tumors.
