- BACKGROUND: In recent years, the fallopian tubes have been found to play a critical role in the pathogenesis of ovarian cancer. Therefore, bilateral salpingectomy at the time of hysterectomy has been proposed as a preventive procedure, but with scarce scientific evidence to support the efficiency and safety. OBJECTIVE: Our primary objective was to evaluate the risk of surgical complications and menopausal symptoms when performing bilateral salpingectomy in addition to benign hysterectomy. Furthermore, we sought to compare time in surgery, perioperative blood loss/blood transfusion, duration of hospital stay, days to normal activities of daily living, and days out of work for hysterectomy with bilateral salpingectomy compared with hysterectomy only. A secondary objective was to study the uptake of opportunistic salpingectomy in Sweden. STUDY DESIGN: This was a retrospective observational cohort study based on data from the National Quality Register of Gynecological Surgery in Sweden. Women <55 years of age who had a hysterectomy for benign indications with or without bilateral salpingectomy in 1998 through 2016 were included. Possible confounding was adjusted for in multivariable regression models. RESULTS: During the study period, 23,369 women had a hysterectomy for benign indications. The frequency of bilateral salpingectomy at the time of hysterectomy increased mainly from 2013, which is why the period 2013 through mid-2016 was selected for further analysis (n = 6892). There was a low frequency of vaginal hysterectomy with bilateral salpingectomy performed in this period, which is why only abdominal and laparoscopic surgeries were selected for comparative analysis (n = 4906). This study indicates an increased risk of menopausal symptoms (adjusted relative risk, 1.33; 95% confidence interval, 1.04-1.69) 1 year after hysterectomy with bilateral salpingectomy compared with hysterectomy only. Hospital stay was 0.1 days longer in women having salpingectomy (P = .01), and bleeding was slightly reduced in the salpingectomy group (-20 mL, P = .04). Other outcome measures were not significantly associated with salpingectomy, albeit a tendency toward higher risk of minor complications was seen (adjusted relative risk, 1.30; 95% confidence interval, 0.93-1.83). CONCLUSION: Bilateral salpingectomy at the time of hysterectomy was associated with an increased risk of menopausal symptoms 1 year after surgery. Randomized clinical trials reducing the risk of residual and unmeasured confounding and longer follow-up are needed to correctly inform women on the risks and benefits of opportunistic salpingectomy.

- Introduction: Complications after gynecological surgery in Sweden are registered in the well-established Swedish National Quality Register of Gynecological Surgery, GynOp. The aim of this study was to analyze interrater reliability in assessing complications according to the methods in GynOp, and to explore physicians' perceptions of registering complications.Material and methods: A digital survey was sent to gynecologists and residents in gynecology in Sweden. Participating clinics were recruited through the Swedish network for national clinical studies in Obstetrics and Gynecology, SNAKS. Twenty fictional cases, intended to represent normal postoperative course, failure to cure, and varying degrees of complications, were developed by the research group. The clinical scenarios included abdominal and laparoscopic surgery of the uterus and adnexa, vaginal hysterectomies, as well as hysteroscopy. The respondents graded each case on the presence of a complication (yes/no). Type of complication, severity, and what action the complication required according to Clavien-Dindo was registered if a complication was acknowledged, according to the method in GynOp. Interrater reliability and the opinions of the respondents were presented descriptively. More than 80% of respondents making the same assessment was considered as agreement.Results: The response rate was 41%, with 104 responding physicians from 16 gynecological clinics. Type and severity of complication was considered relevant to register by 88% and 89% of respondents, respectively. Agreement on whether the case described a complication was >80% in 85% (17/20) of cases and agreement using the Clavien-Dindo classification was >90% in 80% (16/20) of cases. There was high agreement in assessments of classically severe complications, such as pulmonary embolism and ureteral damage, in both presence of complication and severity, as well as Clavien-Dindo (>90% for all methods). Cases with agreement <80% on whether the case described a complication were bordering between normal postoperative course and minor complication.Conclusions: This study provides validation for the methods used to register complications after gynecological surgery according to the GynOp register, including the use of Clavien-Dindo in gynecology. However, the results indicate a need to define what should be considered symptoms inherent to each type of surgery.

Tidskriftsartikel (refereegranskat)abstract
- Background The HOPPSA trial is a multi-center national registry-based randomized controlled trial to test the safety and effectiveness of performing opportunistic salpingectomy at hysterectomy to reduce the risk of epithelial ovarian cancer (EOC). The study protocol was first published in January 2019 and is available at . Here, we report amendments made to the study protocol since commencement of the trial.Changes in methods and analysis The primary outcomes analyses have been changed. (1) Complications will be analyzed using binomial generalized estimating equation (GEE) with log link function, while the unadjusted analyses according to Miettinen and Nurminen will be performed as a sensitivity analysis. (2) Absolute change in Menopause Rating Scale (MRS) will primarily be analyzed using a mixed effects model, adjusted for baseline MRS and center as a random effect. (3) Time to EOC will be analyzed using the mixed effects Cox regression model with center as random effect, while the unadjusted log-rank test will be performed as a sensitivity analysis.The primary outcome Complications will be based solely on the specific assessment in the GynOp quality registry. The Clavien-Dindo classification will be evaluated as a secondary outcome.Furthermore, MRS is also measured three years postoperatively to better pinpoint the onset of menopausal symptoms.Discussion The changes to the protocol mainly concern the analyses of data. No changes to recruitment, randomization, intervention, or follow-up of primary outcomes have been made. An interim analysis during 2021 concluded that the study should continue until the target sample size is reached.

Hysterectomy and opportunistic salpingectomy (HOPPSA): study protocol for a register-based randomized controlled trial
- 2019

- BackgroundThere is a great need for a prospective randomized trial to evaluate the risks and benefits of opportunistic salpingectomy. Recently, genetic and morphologic studies have indicated that epithelial ovarian cancer predominantly develops in the Fallopian tubes. Consequently, there is reason to believe that salpingectomy would reduce the risk of ovarian cancer. Studies on reducing the risk of ovarian cancer have compared indicated salpingectomy with no salpingectomy, while studies on surgical safety as well as ovarian function after opportunistic salpingectomy have been small with a short follow-up. No study has reported menopausal symptoms.Methods/designIn this national register-based randomized controlled trial, women <55years old, planned for a hysterectomy for a benign cause, will be randomized to concomitant salpingectomy or no salpingectomy. The follow-up will be conducted according to already established routines within the register using on-line questionnaires. Primary outcomes have been defined for three different time points: short-term complications up to 8 weeks postoperatively (n=2800), intermediate-term changes in menopausal symptoms measured by the Menopause Rating Scale at baseline and after 1 year (n=1670), and long-term epithelial ovarian cancer assessed through national registers after 30years (n=5052) (or n=7001 for high-grade serous cancer). In a sub-study of 75 women, ovarian function will be evaluated through change in anti-Mullerian hormone measured before surgery and after 1 year.DiscussionHysterectomy for a benign cause is a common surgical procedure and several national societies recommend salpingectomy while performing a benign hysterectomy, despite a lack of scientific evidence for the safety of the procedure. Sweden has unique conditions for clinical trials because of its national quality registers and health registers with excellent quality and near complete coverage. If no additional risks are associated with concomitant salpingectomy, it can be recommended at the time of benign hysterectomy to reduce the risk of epithelial ovarian cancer. If not, the risks and benefits must be balanced. The results of this study will be important for informing women undergoing a benign hysterectomy.Trial registrationClinicalTrials.gov, NCT03045965.

Forskningsöversikt (refereegranskat)abstract
- Purpose: The objective of this systematic review is to evaluate current literature comparing salpingectomy for sterilisation with tubal ligation, regarding the effectiveness and safety, and assess the certainty of evidence. Materials and methods: PubMed, Cochrane, and Embase databases were searched. Randomised (RCT) and observational studies were included. Articles were quality assessed and data extracted by two independent authors. Certainty of evidence was assessed using GRADE. Results: Of 2020 articles, 17 were included. No study investigated the risk of EOC. No difference in anti-Müllerian hormone was reported in one RCT at caesarean section (CS). Two cohort studies evaluated ovarian function with surrogate measures and found no difference at caesarean section. Complications did not differ but were inconsistently reported. Laparoscopic tubal ligation was 7 min faster (95% CI 3.8–10.5). Operative time at caesarean section was dependent on the use of surgical devices. Certainty of evidence was low or very low for all estimates, indicating knowledge gaps. Reliable safety data on salpingectomy for sterilisation is lacking, and there is no effectiveness data. Presently, women cannot be properly counselled regarding salpingectomy for sterilisation.

- Salpingectomy is currently suggested as an alternative to tubal ligation for sterilisation. Precursor lesions of ovarian carcinoma can be found in the fallopian tubes; thus, salpingectomy could possibly reduce the incidence. Most of the existing trials on safety are small, on caesarean section and report on surrogate ovarian function measures. Randomised trials in laparoscopy are lacking. Well-designed trials are needed to evaluate safety of laparoscopic opportunistic salpingectomy.In SALSTER, a national register-based randomised controlled non-inferiority trial, 968women <50 years, wishing laparoscopic sterilisation will be randomised to either salpingectomy or tubal ligation. The Swedish National Quality Register of Gynecological Surgery (GynOp) will be used for inclusion, randomisation and follow-up. Primary outcomes are any complication up to 8weeks postoperatively, and age at menopause. Both outcomes are measured with questionnaires, complications are also assessed by a gynaecologist. In a nested trial, ovarian function will be evaluated comparing the mean difference of anti-Müllerian hormone (AMH), assessed preoperatively and 1year after surgery.Performing salpingectomy for sterilisation has become increasingly common, despite the unclear risk-benefit balance. SALSTER studies the safety of salpingectomy compared with tubal ligation. Regardless of the result, SALSTER will provide gynaecologists with high quality evidence to inform women to decide on salpingectomy or not. The central ethical review board of Gothenburg, Sweden (Dnr. 316-18) approved the trial in 2018. Results will be presented at scientific congresses and published in peer-reviewed scientific journals. The results will be communicated through professional organisations and research networks.NCT03860805.

- To improve the accuracy of chemoradiation therapy in anal cancer patients PET/CT is frequently used in the planning of radiation therapy. A systematic review was performed to assess impact on survival, quality of life, symptom score, change in target definition and treatment intention. Systematic literature searches were conducted in Medline, EMBASE, the Cochrane Library, and Centre for Reviews and Dissemination. Ten cross-sectional studies were identified. No data were available on survival or quality of life. The summary estimate of the proportion of patients in which PET/CT had an impact on the target definition, was 23% (95% CI 16;33). The corresponding summary estimate of a change in treatment intent from curative to palliative was 3% (95% CI 2;6). Almost one in four patients had a change in target definition, which supports the use of PET/CT in radiation therapy planning, but the consequence regarding survival and quality of life is still uncertain.

- HTA (health technology assessment) innebär en systematisk granskning av det vetenskapliga underlaget för en viss teknik. Ett väl definierat PICO (patients, intervention, comparison, outcome) är en grundförutsättning för att få fram den dokumentation som ska granskas. En fokuserad fråga är central i HTA-processen. En teknik granskas med avseende på effektivitet och risker, etiska och organisatoriska aspekter samt kostnader. I en systematisk litteraturöversikt granskas vetenskapliga artiklar med avseende på kvalitet och relevans. Slutsatserna evidensgraderas enligt GRADE. I Västra Götalandsregionen har inrättats ett HTA-centrum som arbetar med regional medicinsk utvärdering. Regionalt HTA-arbete har flera fördelar; en är att den praktiska omsättningen av de nyvunna kunskaperna troligen kan ske snabbare.
