Comparison of analgesic efficacy of tramadol, morphine and methadone in cats undergoing ovariohysterectomy.

OBJECTIVES: The aim of this study was to compare the analgesic efficacy and the effect on physiological variables and behavior of the use of tramadol, methadone and morphine as preoperative analgesia in healthy cats undergoing elective ovariohysterectomy. METHODS: Cats undergoing ovariohysterectomy were randomly assigned to receive one of the following premedication treatments intramuscularly: methadone (0.2 mg/kg; n = 10); morphine (0.2 mg/kg; n = 10); or tramadol (3 mg/kg; n = 10). Induction of anesthesia was done with propofol, and maintenance of anesthesia was done with isoflurane. Intraoperative heart rate, arterial blood pressure, respiratory rate, end-tidal isoflurane concentration and frequency of rescue analgesia (fentanyl 2.5 µg/kg) were compared between groups. Postoperative analgesia was assessed using the UNESP-Botucatu Multidimensional Composite Pain Scale, and perioperative serum glucose, cortisol concentrations and postoperative rescue analgesia were evaluated. RESULTS: Intraoperative rescue analgesia was required in 76.5% of cats at some time during surgery, and 27% of cats required postoperative rescue analgesia up to 6 h after extubation. There were no significant differences between groups with respect to intraoperative and postoperative rescue analgesia, pain scale scores and end-tidal isoflurane concentrations. In the immediate postoperative period, after extubation, most of the patients presented with hypothermia; however, 1-6 h postoperatively, hyperthermia was observed in most of the patients, and was most common in the tramadol group. CONCLUSIONS AND CLINICAL RELEVANCE: Under the conditions of this study, methadone, morphine and tramadol produced satisfactory postoperative analgesia in most of the cats undergoing ovariohysterectomy, and the effects lasted up to 6 h postoperatively. Intraoperative analgesia was not sufficient in most cases. Significant cardiovascular or respiratory effects contraindicating the use of these drugs were not found. Postanesthetic hyperthermia occurred with all opioids studied and was more frequent in the tramadol group.

Oncologic and reproductive outcomes after fertility-sparing surgery for bilateral borderline ovarian tumors: A retrospective study.

OBJECTIVES: To investigate the oncological safety and fertility outcomes of different fertility-sparing surgery procedures for bilateral borderline ovarian tumors (BOTs) and to identify the safest and most effective approach to help patients conceive with minimal risk. STUDY DESIGN: A retrospective study of 144 patients (≤40 years) with pathologically confirmed bilateral BOTs were included in the study.The effects of surgery type on fertility outcome and recurrence were compared. Cox regression analysis was employed to determine potential prognostic factors. Survival analysis utilized the Kaplan-Meier method. RESULTS: Three therapeutic modalities were applied in our study, including bilateral ovarian cystectomy (BOC; n = 29), unilateral adnexectomy + contralateral cystectomy (UAC; n = 4) and radical surgery (n = 61). Totally 33 cases (22.9 %) relapsed during the follow-up period. In 37 % of cases administered conservative surgery, relapses were diagnosed in the first 2 years. Only conservative surgery and adjuvant chemotherapy were risk factors for recurrence. Meanwhile, a pregnancy rate of 55.4 % was obtained in patients with bilateral BOTs. The pregnancy rate was slightly higher but no significant (P = 0.539) difference in patients treated with BOC (n = 17, 63 %) compared with UAC (n = 29, 55.8 %) group. GnRHa treatment significantly improved the clinical pregnancy rate in this study(P = 0.029). CONCLUSIONS: Satisfactory pregnancy rate can be achieved after conservative surgery in patients with bilateral BOTs. BOC is worth recommending for bilateral borderline ovarian tumors and a critical factor in fertility is the preservation of maximum healthy ovarian tissue. Patients should make a pregnancy plan in 2 years after the first surgery. GnRHa increase the rate of successful clinical pregnancies.

Screening and prevention of ovarian cancer.

Ovarian cancer remains the most lethal gynaecological malignancy with 314 000 cases and 207 000 deaths annually worldwide. Ovarian cancer cases and deaths are predicted to increase in Australia by 42% and 55% respectively by 2040. Earlier detection and significant downstaging of ovarian cancer have been demonstrated with multimodal screening in the largest randomised controlled trial of ovarian cancer screening in women at average population risk. However, none of the randomised trials have demonstrated a mortality benefit. Therefore, ovarian cancer screening is not currently recommended in women at average population risk. More frequent surveillance for ovarian cancer every three to four months in women at high risk has shown good performance characteristics and significant downstaging, but there is no available information on a survival benefit. Population testing offers an emerging novel strategy to identify women at high risk who can benefit from ovarian cancer prevention. Novel multicancer early detection biomarker, longitudinal multiple marker strategies, and new biomarkers are being investigated and evaluated for ovarian cancer screening. Risk-reducing salpingo-oophorectomy (RRSO) decreases ovarian cancer incidence and mortality and is recommended for women at over a 4-5% lifetime risk of ovarian cancer. Pre-menopausal women without contraindications to hormone replacement therapy (HRT) undergoing RRSO should be offered HRT until 51 years of age to minimise the detrimental consequences of premature menopause. Currently risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) should only be offered to women at increased risk of ovarian cancer within the context of a research trial. Pre-menopausal early salpingectomy is associated with fewer menopausal symptoms and better sexual function than bilateral salpingo-oophorectomy. A Sectioning and Extensively Examining the Fimbria (SEE-FIM) protocol should be used for histopathological assessment in women at high risk of ovarian cancer who are undergoing surgical prevention. Opportunistic salpingectomy may be offered at routine gynaecological surgery to all women who have completed their family. Long term prospective opportunistic salpingectomy studies are needed to determine the effect size of ovarian cancer risk reduction and the impact on menopause.

Standing hand-assisted laparoscopic ovariohysterectomy to treat chronic pyometra in a mare.

OBJECTIVE: To describe a standing hand-assisted laparoscopic ovariohysterectomy in a mare. ANIMAL: A 15-year-old maiden Oldenburg mare. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The mare was presented for evaluation of bucking under saddle and uncharacteristic aggressive behavior. Evaluation of a 24-hour video of the mare in a stall showed behavior consistent with caudal visceral abdominal discomfort. Reproductive evaluation revealed a pyometra secondary to complete transluminal cervical adhesions. The mare was initially managed medically with disruption of the adhesions and uterine lavage, but the adhesions reformed within 6 weeks and could not be manually disrupted. TREATMENT AND OUTCOME: To eliminate the recurrence of pyometra, the mare underwent standing hand-assisted laparoscopic ovariohysterectomy through bilateral flank incisions. The only complication was a seroma at 1 flank incision that resolved after drainage. CLINICAL RELEVANCE: Complete ovariohysterectomy in the mare is a challenging procedure and has previously been performed under general anesthesia. This is the first report of the procedure being performed completely in the standing mare without inversion of the uterus through the cervix.

[Ovarian masses in infants and children]. / Raumforderungen des Ovars im Kindesalter.

BACKGROUND: Abnormalities of the ovary are frequently seen on ultrasound examination, sometimes symptomatic, but are more commonly asymptomatic. PURPOSE: Presentation of the most important entities of ovarian masses and their imaging features in infants and children. Discussion of criteria for differentiation between benign and potentially malignant masses. MATERIALS AND METHODS: Review of current literature and presentation of image examples. RESULTS: The most common lesions are ovarian cysts in infants, which usually do not require therapy. Because of the risk of torsion, surgery should be discussed for lesions with a size of 5 cm or more. Benign teratomas represent three-quarters of all solid tumors of the infantile ovary. Malignant masses are rare. The task of imaging is to assess the potential risk of malignancy, also using imaging scores. CONCLUSIONS: Imaging plays a crucial role for therapeutic considerations. Depending on the potential risk, ovarian-sparing surgery is preferred to preserve fertility, as long as the oncologic risk is reasonable.

Advantages of laparoscopic-assisted ovariohysterectomy versus open ovariohysterectomy for dogs with pyometra not detected in randomized clinical trial.

OBJECTIVE: To compare results for surgery time, perioperative pain, need for rescue analgesia, variables, serum C-reactive protein concentration, and postoperative complications for dogs with pyometra treated with laparoscopic-assisted ovariohysterectomy (LaOVH) versus open-surgery (OS) ovariohysterectomy. ANIMALS: 12 client-owned dogs with pyometra between June 1, 2016, and December 31, 2019. METHODS: Dogs enrolled in this prospective single-center randomized clinical trial had pyometra confirmed by history, physical examination, ultrasonography, and blood work and were randomly assigned to treatment group LaOVH or OS. Differences in results for variables of interest were compared between groups using the Mann-Whitney U test, except the number of dogs requiring rescue analgesia was analyzed using the Fisher exact test. Values of P ≤ .05 were considered significant. RESULTS: 6 dogs were recruited in each group; results for 1 dog in the LaOVH group were excluded from further analysis due to free abdominal fluid detected during surgery. Median surgery time was significantly shorter and median total incision length was longer for the OS group (23 minutes; 106 mm), compared to the LaOVH group (37 minutes; 38 mm). No other results differed significantly between groups. CLINICAL RELEVANCE: Although fewer patients in the LaOVH group required rescue analgesia, this was not statistically significant. Therefore, our results could not prove previously suggested advantages of LaOVH (eg, less perioperative pain or faster recovery) in dogs with pyometra. Additionally, for the LaOVH group, the median surgical time was approximately 50% longer, an assistant was needed, and specialized equipment was required.

Impact of Oophorectomy on Survival and Improving Nutritional Status in Ovarian Metastasis from Colorectal Adenocarcinoma.

INTRODUCTION: Ovarian metastasis of colorectal cancer is known to have a poor prognosis. This study aimed to elucidate the characteristics of patients who underwent oophorectomy for ovarian metastasis from colorectal cancer. METHODS: This retrospective study included 16 patients who underwent oophorectomy for colorectal cancer metastasis to the ovary from January 2004 to December 2017. Improvement in patient's symptoms and pre- and postoperative changes in various nutritional and inflammatory indicators were assessed. Survival analysis and identification of prognostic factors were conducted with a median follow-up of 40.7 (5-109) months. RESULTS: Of 16 patients, 12 had (75%) synchronous and 4 (25%) had metachronous metastasis. Fourteen patients were symptomatic but symptoms resolved postoperatively. Thirteen patients (81.3%) had ascites and 5 (31.3%) had pleural effusion on preoperative computed tomography that disappeared after surgery in all cases. The median value of prognostic nutritional factor was significantly increased postoperatively (36.0 [preoperatively] vs. 47.5, p < 0.0001). The median (interquartile range) values for lymphocyte-C-reactive protein ratio were 715.2 (110-2,607) preoperatively and 6,095.2 (1,612.3-14,431.8) postoperatively (p = 0.0214). The median survival of the entire cohort was 60.4 months. The 3-year survival rates for R0 + R1 and R2 cases were 83% and 24% (p = 0.018), respectively. Univariate analysis showed that R2 resection and low postoperative lymphocyte-C-reactive protein ratio were associated with poor prognosis. CONCLUSIONS: Oophorectomy for ovarian metastasis from colorectal cancers was safely performed. It improved the patients' symptoms and nutritional status and may result in improved prognosis.

Bilateral salpingo-oophorectomy at the time of benign hysterectomy among females with disabilities: a population-based cross-sectional study.

BACKGROUND: Up to 40% of patients aged ≤55 years undergo concomitant bilateral salpingo-oophorectomy at the time of benign hysterectomy, with practice variation in bilateral salpingo-oophorectomy occurring along the lines of patient health and social factors. Disability is common in premenopausal women and is an important determinant of reproductive health more broadly; however, studies on bilateral salpingo-oophorectomy rates among women with disabilities are lacking. OBJECTIVE: This study aimed to examine whether the use of concomitant bilateral salpingo-oophorectomy at the time of benign hysterectomy differs by preexisting disability status in adult females aged ≤55 years. STUDY DESIGN: This population-based cross-sectional study used data from the 2016-2019 US National Inpatient Sample. Females undergoing inpatient hysterectomy for a benign gynecologic indication (n=74,315) were classified as having physical (6.1%), sensory (0.1%), intellectual or developmental (0.2%), or multiple (0.2%) disabilities and compared with those without a disability. Logistic regression was used to estimate risk ratios for differences in bilateral salpingo-oophorectomy rates by disability status, adjusted for patient and clinical factors. Models were stratified by potentially avoidable or potentially appropriate bilateral salpingo-oophorectomy based on the presence of clinical indications for ovarian removal and by age group. RESULTS: Bilateral salpingo-oophorectomy at the time of benign hysterectomy occurred in 26.0% of females without a disability, with rates clearly elevated in those with a physical (33.2%; adjusted risk ratio, 1.10; 95% confidence interval, 1.05-1.14) or intellectual or developmental (31.1%; adjusted risk ratio, 1.32; 95% confidence interval, 1.02-1.64) disability, possibly elevated in those with multiple disabilities (38.2%; adjusted risk ratio, 1.20; 95% confidence interval, 0.94-1.45), and similar in those with a sensory disability (31.2%; adjusted risk ratio, 0.98; 95% confidence interval, 0.83-1.13). The results were similar but with lower statistical precision for potentially avoidable and potentially appropriate bilateral salpingo-oophorectomy, which occurred in 9.1% and 17.0% of females without a disability, respectively. The largest differences in bilateral salpingo-oophorectomy rates among women with any disability were observed in the perimenopausal 45- to 49-year age group. CONCLUSION: Females with disabilities experienced elevated concomitant bilateral salpingo-oophorectomy rates at the time of benign hysterectomy, particularly those with an intellectual or developmental disability and those of perimenopausal age, although some estimates were imprecise. Equity-focused physician training in surgical counseling and research into the epidemiology and experiences of gynecologic conditions among females with a disability may be beneficial.

Changes in Bone Density in Carriers of BRCA1 and BRCA2 Pathogenic Variants After Salpingo-Oophorectomy.

OBJECTIVE: To evaluate the effect of risk-reducing salpingo-oophorectomy (RRSO) on change in bone mineral density (BMD) in women aged 34-50 years with pathogenic variants in BRCA1 or BRCA2 ( BRCA1 /2). METHODS: The PROSper (Prospective Research of Outcomes after Salpingo-oophorectomy) study is a prospective cohort of women aged 34-50 years with BRCA1 or two germline pathogenic variants that compares health outcomes after RRSO to a non-RRSO control group with ovarian conservation. Women aged 34-50 years, who were planning either RRSO or ovarian conservation, were enrolled for 3 years of follow-up. Spine and total hip BMD were measured by dual-energy X-ray absorptiometry (DXA) scans obtained at baseline before RRSO or at the time of enrollment for the non-RRSO group, and then at 1 and 3 years of study follow-up. Differences in BMD between the RRSO and non-RRSO groups, as well as the association between hormone use and BMD, were determined by using mixed effects multivariable linear regression models. RESULTS: Of 100 PROSper participants, 91 obtained DXA scans (RRSO group: 40; non-RRSO group: 51). Overall, total spine, and hip BMD decreased significantly from baseline to 12 months after RRSO (estimated percent change -3.78%, 95% CI -6.13% to -1.43% for total spine; -2.96%, 95% CI -4.79% to -1.14% for total hip) and at 36 months (estimated percent change -5.71%, 95% CI -8.64% to -2.77% for total spine; -5.19%, 95% CI -7.50% to -2.87% for total hip. In contrast, total spine and hip BMD were not significantly different from baseline for the non-RRSO group. The differences in mean percent change in BMD from baseline between the RRSO and non-RRSO groups were statistically significant at both 12 and 36 months for spine BMD (12-month difference -4.49%, 95% CI -7.67% to -1.31%; 36-month difference -7.06%, 95% CI -11.01% to -3.11%) and at 36 months for total hip BMD (12-month difference -1.83%, 95% CI -4.23% to 0.56%; 36-month difference -5.14%, 95% CI -8.11% to -2.16%). Across the study periods, hormone use was associated with significantly less bone loss at both the spine and hip within the RRSO group compared with no hormone use ( P <.001 at both 12 months and 36 months) but did not completely prevent bone loss (estimated percent change from baseline at 36 months -2.79%, 95% CI -5.08% to -0.51% for total spine BMD; -3.93%, 95% CI -7.27% to -0.59% for total hip BMD). CONCLUSION: Women with pathogenic variants in BRCA1 /2 who undergo RRSO before the age of 50 years have greater bone loss after surgery that is clinically significant when compared with those who retain their ovaries. Hormone use mitigates, but does not eliminate, bone loss after RRSO. These results suggest that women who undergo RRSO may benefit from routine screening for BMD changes to identify opportunities for prevention and treatment of bone loss.

Correlation analysis of hysterectomy and ovarian preservation with depression.

The relationship between hysterectomy and ovarian preservation and depression is controversial. This study aimed to determine the association of hysterectomy and ovarian preservation with depression using National Health and Nutrition Examination Survey. To assess the association between hysterectomy with or without ovariectomy and depression, we used 3 methods. Method 1: propensity score model (PSM) was established. Method 2 was logistics regression analysis of hysterectomy and depression before and after PSM. Method 3 was a logistics regression analysis of the relationship between hysterectomy and different depressive symptoms. At the same time, in order to evaluate the association between hysterectomy with or without oophorectomy and depression, we explored the effect of four different surgical procedures on depression using logistic regression equations. We enrolled 12,097 women, of whom 2763 underwent hysterectomy, 34.455% were positive for depression. After weighting, 33.825% of the total sample had a PHQ ≥ 5. Finally, a total of 2778 women were successfully matched by propensity score, and 35.537% of them were positive for depression. The OR for PHQ ≥ 5 was 1.236 after crude adjustment of covariates and 1.234 after exact adjustment. This suggests that Hysterectomy is strongly associated with positive depression. Positive depression (PHQ ≥ 5) was associated with little interest, feeling down and trouble concentrating. It was not associated with trouble sleeping, feeling tired, poor appetite, feeling bad, slow moving or speaking, and suicidal thoughts. Oophorectomy-alone is not associated with depression. Hysterectomy-alone is a risk factor for depression, but Hysterectomy combined with Oophorectomy has a stronger correlation with depression than Hysterectomy-alone. Women who have had a Hysterectomy are at higher risk of depression than women who have not had a Hysterectomy, and this risk may be exacerbated if the uterus and ovaries are removed. When clinically appropriate, surgeons should try to preserve the patient's ovaries.

Laparoscopic Excision of Retroperitoneal Adnexal Cyst.

STUDY OBJECTIVE: To demonstrate the laparoscopic excision of a retroperitoneal adnexal cyst and describe the advanced surgical techniques and anatomic considerations in a patient with previous abdominopelvic surgery. DESIGN: Stepwise demonstration of advanced laparoscopic techniques with narrated video footage. SETTING: Adnexal masses after hysterectomy are a common reason for repeat abdominal surgery.1 Up to 9% of patients may require future adnexal surgery if ovarian preservation was chosen at the time of hysterectomy.2 Indications for surgery can include persistent adnexal masses, masses with concern for malignancy, chronic pelvic pain, and risk-reducing surgery.2 This patient is a 53-year-old postmenopausal female with a history of a total abdominal hysterectomy and left salpingectomy who underwent excision of an 8 cm retroperitoneal left adnexal cyst (Still 1). INTERVENTIONS: Excision of a retroperitoneal adnexal cyst can be performed through a laparoscopic approach with several key strategies: CONCLUSION: Knowledge of retroperitoneal anatomy is crucial in the surgical management of retroperitoneal adnexal masses because dissection can be technically challenging and anatomy may be distorted due to pelvic adhesive disease. Use of advanced laparoscopic techniques and understanding surgical planes are important for safe dissection. High and early ligation of the infundibulopelvic ligament at the pelvic brim and a complete ureterolysis with parametrial excision are often necessary to remove all ovarian tissue to prevent an ovarian remnant.

Patient perspectives on risk-reducing salpingectomy with delayed oophorectomy for ovarian cancer risk-reduction: A systematic review of the literature.

OBJECTIVE: Increasing evidence suggests the fallopian tube as the site of origin of BRCA1/2-associated high-grade ovarian cancers. Several ongoing trials are evaluating salpingectomy with delayed oophorectomy (RRSDO) for ovarian cancer risk reduction and patients are beginning to ask their clinicians about this surgical option. This study sought to systematically review the available literature examining patient preferences regarding RRSDO and risk-reducing salpingo-oophorectomy (RRSO) to provide clinicians with an understanding of patient values, concerns, and priorities surrounding ovarian cancer risk-reducing surgery. METHODS: We conducted a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO No.: CRD42023400690). We searched key electronic databases to identify studies evaluating acceptance and surgical decision-making regarding RRSO and RRSDO among patients with an increased risk of ovarian cancer. RESULTS: The search yielded 239 results, among which six publications met the systematic review inclusion criteria. Acceptance of RRSDO was evaluated in all studies and ranged from 34% to 71%. Factors positively impacting patients' acceptance of RRSDO included: avoidance of surgical menopause, preservation of fertility, concerns about sexual dysfunction, family history of breast cancer, and avoidance of hormone replacement therapy. Factors limiting this acceptance reported by patients included concerns regarding oncologic safety, surgical timing, and surgical complications. CONCLUSION: To date, few studies have explored patient perspectives surrounding RRSDO. Collectively, the limited data available indicate a high level of acceptance among BRCA1/2 carriers, and provides insight regarding both facilitating and limiting factors associated with patient preferences to better equip clinicians in the counseling and support of their patients.

Canine laparoscopic-assisted ovary-sparing hysterectomy does not increase risk of stump pyometra.

OBJECTIVE: To evaluate incidences of pyometra and orthopedic, behavioral, urinary/reproductive, neoplastic, or atopic disease processes as outcomes for dogs undergoing either a laparoscopic-assisted ovary-sparing spay/hysterectomy (LapOSS) or a laparoscopic ovariectomy (LapOVE). ANIMALS: 33 client-owned dogs. PROCEDURES: Medical records of client-owned dogs presenting between August 2013 and May 2020 for elective LapOSS or LapOVE were reviewed. A multiple-choice client questionnaire was emailed to all clients whose dogs' complete medical records were available. RESULTS: 17 of the 33 dogs were in the LapOSS group, and 16 of 33 dogs were in the LapOVE group. Of the 17 dogs undergoing LapOSS, 5 of 17 (29%) underwent an elective OVE at a later date. The mean follow-up time was 4.2 ± 1.8 years for the LapOSS group and 4.3 ± 2.0 years for the LapOVE group. No dogs developed stump pyometra. One LapOSS dog developed mammary tumor, and 2 others developed nonreproductive malignant neoplasia while 2 of the LapOVE dogs developed malignant neoplasia. One of the LapOSS dogs with malignant neoplasia had an ovariectomy prior to development of disease. CLINICAL RELEVANCE: Laparoscopic-assisted ovary-sparing spay appears to provide a safe and reliable method of sterilization, with no observable increased risk of pyometra with hysterectomy. Owners must be counseled prior to surgery regarding the consequences of gonadal hormone retention and multiple heat cycles.

TUBectomy with delayed oophorectomy as an alternative to risk-reducing salpingo-oophorectomy in high-risk women to assess the safety of prevention: the TUBA-WISP II study protocol.

BACKGROUND: Risk-reducing salpingectomy with delayed oophorectomy has gained interest for individuals at high risk for tubo-ovarian cancer as there is compelling evidence that especially high-grade serous carcinoma originates in the fallopian tubes. Two studies have demonstrated a positive effect of salpingectomy on menopause-related quality of life and sexual health compared with standard risk-reducing salpingo-oophorectomy. PRIMARY OBJECTIVE: To investigate whether salpingectomy with delayed oophorectomy is non-inferior to the current standard salpingo-oophorectomy for the prevention of tubo-ovarian cancer among individuals at high inherited risk. STUDY HYPOTHESIS: We hypothesize that postponement of oophorectomy after salpingectomy, to the age of 40-45 (BRCA1) or 45-50 (BRCA2) years, compared with the current standard salpingo-oophorectomy at age 35-40 (BRCA1) or 40-45 (BRCA2) years, is non-inferior in regard to tubo-ovarian cancer risk. TRIAL DESIGN: In this international prospective preference trial, participants will choose between the novel salpingectomy with delayed oophorectomy and the current standard salpingo-oophorectomy. Salpingectomy can be performed after the completion of childbearing and between the age of 25 and 40 (BRCA1), 25 and 45 (BRCA2), or 25 and 50 (BRIP1, RAD51C, and RAD51D pathogenic variant carriers) years. Subsequent oophorectomy is recommended at a maximum delay of 5 years beyond the upper limit of the current guideline age for salpingo-oophorectomy. The current National Comprehensive Cancer Network (NCCN) guideline age, which is also the recommended age for salpingo-oophorectomy within the study, is 35-40 years for BRCA1, 40-45 years for BRCA2, and 45-50 years for BRIP1, RAD51C, and RAD51D pathogenic variant carriers. MAJOR INCLUSION/EXCLUSION CRITERIA: Premenopausal individuals with a documented class IV or V germline pathogenic variant in the BRCA1, BRCA2, BRIP1, RAD51C, or RAD51D gene who have completed childbearing are eligible for participation. Participants may have a personal history of a non-ovarian malignancy. PRIMARY ENDPOINT: The primary outcome is the cumulative tubo-ovarian cancer incidence at the target age: 46 years for BRCA1 and 51 years for BRCA2 pathogenic variant carriers. SAMPLE SIZE: The sample size to ensure sufficient power to test non-inferiority of salpingectomy with delayed oophorectomy compared with salpingo-oophorectomy requires 1500 BRCA1 and 1500 BRCA2 pathogenic variant carriers. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Participant recruitment is expected to be completed at the end of 2026 (total recruitment period of 5 years). The primary outcome is expected to be available in 2036 (minimal follow-up period of 10 years). TRIAL REGISTRATION NUMBER: NCT04294927.

Ovarian preservation compared to oophorectomy in premenopausal women with early-stage, low-grade endometrial Cancer: A cost-effectiveness analysis.

OBJECTIVES: Standard treatment for endometrial cancer is a hysterectomy, bilateral salpingo-oophorectomy, and lymph node assessment. In premenopausal women, removal of the ovaries may not be necessary and could increase the risk of all-cause mortality. We sought to estimate the outcomes, costs, and cost-effectiveness of oophorectomy versus ovarian preservation in premenopausal women with early-stage, low-grade endometrial cancer. METHODS: A decision-analytic model was designed using TreeAge software comparing oophorectomy to ovarian preservation in premenopausal women with early-stage, low-grade endometrial cancer. We used a theoretical cohort of 10,600 women to represent our population of interest in the United States in 2021. Outcomes included cancer recurrences, ovarian cancer diagnoses, deaths, rates of vaginal atrophy, costs, and quality-adjusted life years (QALYs). The cost-effectiveness threshold was set at $100,000/QALY. Model inputs were derived from the literature. Sensitivity analyses were conducted to evaluate the robustness of the results. RESULTS: Oophorectomy resulted in more deaths and higher rates of vaginal atrophy, while ovarian preservation resulted in 100 cases of ovarian cancer. Ovarian preservation resulted in lower costs and higher QALYs making it cost effective when compared to oophorectomy. Sensitivity analyses demonstrated the probability of cancer recurrence after ovarian preservation and probability of developing ovarian cancer were the most impactful variables in our model. CONCLUSION: Ovarian preservation is cost-effective in premenopausal women with early-stage, low-grade endometrial cancer when compared to oophorectomy. Ovarian preservation may prevent surgical menopause, which may improve quality of life and overall mortality without compromising oncologic outcomes, and should be strongly considered in premenopausal women with early stage disease.

Long-Term Health Consequences After Ovarian Removal at Benign Hysterectomy : A Nationwide Cohort Study.

BACKGROUND: More evidence is needed to substantiate current recommendations about removing ovaries during hysterectomy for benign conditions. OBJECTIVE: To compare long-term outcomes in women with and without bilateral salpingo-oophorectomy (BSO) during hysterectomy for benign conditions. DESIGN: Emulated target trial using data from a population-based cohort. SETTING: Women in Denmark aged 20 years or older during 1977 to 2017. PARTICIPANTS: 142 985 women with hysterectomy for a benign condition, 22 974 with BSO and 120 011 without. INTERVENTION: Benign hysterectomy with or without BSO. MEASUREMENTS: The primary outcomes were overall hospitalization for cardiovascular disease (CVD), overall cancer incidence, and all-cause mortality through December 2018. RESULTS: Compared with women without BSO, women with BSO who were younger than 45 years at surgery had a higher 10-year cumulative risk for hospitalization for CVD (risk difference [RD], 1.19 percentage points [95% CI, 0.09 to 2.43 percentage points]). Women with BSO had a higher 10-year cumulative risk for cancer for ages 45 to 54 years (RD, 0.73 percentage point [CI, 0.05 to 1.38 percentage points]), 55 to 64 years (RD, 1.92 percentage points [CI, 0.69 to 3.25 percentage points]), and 65 years or older (RD, 2.54 percentage points [CI, 0.91 to 4.25 percentage points]). Women with BSO had higher 10-year mortality in all age groups, although the differences were statistically significant only for ages 45 to 54 years (RD, 0.79 percentage point [CI, 0.27 to 1.30 percentage points]). The mortality at 20 years was inconsistent with that at 10 years in women aged 65 years or older. LIMITATION: Age was a proxy for menopausal status. CONCLUSION: The authors find that these results support current recommendations for conserving ovaries in premenopausal women without a high risk for ovarian cancer and suggest a cautious approach in postmenopausal women.

Retrospective review of changes in testosterone dosing and physiologic parameters in transgender and gender-diverse individuals following hysterectomy with and without oophorectomy.

BACKGROUND: As more transgender and gender-diverse patients undergo hysterectomy, gaps in knowledge remain about how testosterone dosing or other physiologic parameters change following surgery and how these are influenced by concomitant oophorectomy. AIM: The aims of this study were to determine the incidence of testosterone dosing change after gender-affirming hysterectomy and to compare this incidence between patients who underwent oophorectomy and ovarian preservation. METHODS: This multicenter retrospective cohort study consisted of transmasculine patients who underwent hysterectomy for gender affirmation. OUTCOMES: Outcome measures included testosterone dosing changes at least 3 months following hysterectomy, as identified by clinical documentation, as well as clinical and laboratory parameters assessed for a change after hysterectomy: free and total testosterone, estradiol, hemoglobin, hematocrit, total cholesterol, weight, and blood pressure. RESULTS: Of the 50 patients, 32 (64%) underwent bilateral oophorectomy, 10 (20%) unilateral oophorectomy, and 8 (16%) maintained both ovaries. Eight percent (n = 4) changed testosterone dosing following hysterectomy. Those who underwent bilateral oophorectomy were no more likely to change their testosterone dose than those who did not (P = .09). Those who also used menstrual suppression were 1.31 times more likely to change doses of testosterone after hysterectomy (95% CI, 1.09-1.82; P = .003). For those who had pre- and posthysterectomy laboratory and clinical values, the majority saw no clinically significant change. However, among patients who underwent bilateral oophorectomy, the calculated free testosterone increased by 90.1 ± 288.4 ng/dL (mean ± SD), and estradiol dropped by 20.2 ± 29.0 pg/mL. CLINICAL IMPLICATIONS: In a field where access to care can be a significant barrier, there is unlikely to be a need for routine reassessment of testosterone dose or laboratory parameters following hysterectomy, whether or not a bilateral oophorectomy occurs. STRENGTHS AND LIMITATIONS: Limitations of the study include its retrospective nature and the lack of consistent clinical laboratory testing, which resulted in limited data about any given hormonal change. The heterogeneity of our population limited the number of patients undergoing or not undergoing oophorectomy; however, it allowed our study to more truly reflect a clinical environment. CONCLUSION: In a multisite cohort of individuals who underwent hysterectomy for gender affirmation, few patients changed testosterone dosing after surgery. In addition, dosing change was not associated with the presence or absence of bilateral oophorectomy, and most measured laboratory values remained consistent following hysterectomy.

Prophylactic salpingectomy with delayed oophorectomy as a two-staged alternative for primary prevention of ovarian cancer in BRCA1/2 mutation carriers: women's point of view.

OBJECTIVE: This study aimed to determine BRCA -mutation carrier women's interest and acceptability of participating in a study examining prophylactic salpingectomy with delayed oophorectomy (PSDO) as an alternative to the current recommendation for bilateral salpingo-oophorectomy for risk reduction. METHODS: This is a cross-sectional questionnaire-based study. All women visiting the high-risk clinics for hereditary breast and ovarian cancer in a single tertiary medical center were asked to complete a questionnaire concerning the two-stage approach from October 2018 to December 2019. Before completing the questionnaire, detailed explanation was given by a senior physician regarding the procedure, related background, possible risks, and benefits. RESULTS: The study population included 293 women, of whom 183 (62.4%) were BRCA1 mutation carriers, 97 (33.1%) were BRCA2 mutation carriers, and 13 (4.4%) had unknown familial mutation. Risk-reducing surgery was completed in 160 (55.17%) of the women. First-degree and second-degree family history was reported in 166 (57.24%) and 52 (17.9%) of the women, respectively. Among women surveyed, more than half of the women (n = 66 [51%]) who had yet to undergo risk-reducing surgery reported interest in having PSDO. Similarly, among those who had already received prophylactic surgery, 64 (40%) also considered PSDO to be an acceptable alternative. Multivariate logistic regression analysis found family history of related malignancies to be the only independent factor associated with reduced interest in a study of PSDO (odds ratio, 0.15 [95% confidence interval, 0.29-0.77]; P = 0.02). CONCLUSIONS: Overall, BRCA -mutation carrier women indicated interest in PSDO risk-reducing surgery, taking into consideration the potential additional risk. These findings suggest that a clinical study exploring the equivalence of PSDO as alternative treatment is feasible.

Piceatannol Prevents Obesity and Fat Accumulation Caused by Estrogen Deficiency in Female Mice by Promoting Lipolysis.

Postmenopausal women have a higher susceptibility to obesity and chronic disease. Piceatannol (PIC), a natural analog of resveratrol, was reported to inhibit adipogenesis and to have an antiobesity effect. In this study, PIC's effect on postmenopausal obesity and the mechanism of its action were investigated. C57BL/6J female mice were divided into four groups and half of them were ovariectomized (OVX). Both OVX and sham-operated mice were fed a high-fat diet (HFD) with and without the addition of 0.25% of PIC for 12 weeks. The abdominal visceral fat volume was higher in the OVX mice than the sham-operated mice, and PIC significantly decreased the fat volume only in the OVX mice. Unexpectedly, expression levels of adipogenesis-related proteins in white adipose tissue (WAT) were suppressed in the OVX mice, and PIC did not affect lipogenesis in either the OVX or sham-operated mice. Regarding the expression of proteins associated with lipolysis, PIC activated the phosphorylation of hormone-sensitive lipase much more in the OVX mice, but it did not affect the expression of adipose triglyceride lipase. PIC also tended to induce the expression of uncoupled protein 1 in brown adipose tissue (BAT). These results suggest that by promoting lipolysis in WAT and deconjugation in BAT, PIC is a potential agent to inhibit fat accumulation caused by menopause.

All-cause and cardiovascular mortality after hysterectomy and oophorectomy in a large cohort (HUNT2).

INTRODUCTION: Hysterectomy and bilateral oophorectomy are common major surgical procedures that have been associated with increased mortality risk. We aimed to assess the association of hysterectomy and/or bilateral oophorectomy with all-cause and cardiovascular mortality in a Norwegian population. MATERIAL AND METHODS: Cohort study with data from The Trøndelag Health Study (HUNT2) linked to the Norwegian Cause of Death Registry, with follow-up from 1996 until 2014 or death. The unexposed group (n = 18 673) included women with both their ovaries and uterus intact, while the two exposed groups included women with hysterectomy alone (n = 1199), or bilateral oophorectomy with or without hysterectomy (n = 907). We compared mortality in exposed vs unexposed groups and adjusted for relevant covariates by Cox regression. Further, we performed analyses stratified by age at surgery (≤39, 40-52, ≥53 years) and subgroup analyses among women ≤52 years of age at inclusion. RESULTS: Among the 47 312 women in HUNT2 (1995-1997), 20 779 provided complete information regarding gynecological surgery and previous health. The hysterectomy group had increased all-cause mortality (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.06-1.58) and cardiovascular mortality (HR 1.47, 95% CI 1.09-1.97). We found no significant association between bilateral oophorectomy and all-cause or cardiovascular mortality in the total population. However, among women ≤52 years at inclusion, cardiovascular mortality was increased in the hysterectomy group (HR 2.71, 95% CI 1.19-6.17) with a similar, but less precise estimate in the bilateral oophorectomy group (HR 2.42, 95% CI 0.84-6.93). CONCLUSIONS: Hysterectomy was associated with increased all-cause and cardiovascular mortality, whereas bilateral salpingo-oophorectomy was not. Among women ≤52 years at inclusion, both hysterectomy and bilateral oophorectomy were associated with a twofold increased risk of cardiovascular mortality, but the results were imprecise. Women after hysterectomy and/or bilateral salpingo-oophorectomy constitute a group with increased cardiovascular mortality that may need closer attention to cardiovascular disease risk from the healthcare system to ensure timely and effective preventive interventions.
