Clinical management among individuals with variant of uncertain significance in hereditary cancer: A systematic review and meta-analysis.

Improper medical use of variant of uncertain significance (VUS) remains a concern in hereditary cancer genetic testing. The goal of this study was to assess the association between pathogenic and likely pathogenic (P/LP), VUS, and benign and likely benign (B/LB) genetic test results and cancer-related surgical and screening management. Systematic searches of Medline, Embase, EBSCO CINAHL Plus, and PsycINFO were conducted from 1946 to August 26, 2020. Eligible studies included individuals with cancer genetic test result and surgical or screening management outcomes. We reviewed 885 abstracts and 22 studies that reported relevant surgical and screening outcomes were included. Meta-analysis revealed significantly higher surgical rates among individuals with P/LP than among those with VUS for therapeutic mastectomy with contralateral prophylactic mastectomy (OR = 7.35, 95% CI, 4.14-13.64), prophylactic mastectomy (OR = 3.05, 95% CI, 1.5-6.19), and oophorectomy (OR = 6.46, 95% CI, 3.64-11.44). There were no significant differences in therapeutic mastectomy, or breast conservation or lumpectomy rates between individuals with P/LP and VUS, or in any outcomes between patients with VUS and B/LB. Studies evaluating screening outcomes were limited, and results were conflicting. Comprehensive analysis do not indicate that a significant number of individuals with VUS results undergo inappropriate clinical management.

Prophylactic gastrostomy in locally advanced head and neck cancer: results of a national survey among radiation oncologists.

BACKGROUND: Nutritional complications in patients with locally advanced head and neck cancer (LA-HNC) treated by concurrent chemoradiotherapy (CCRT) often lead to placement of a prophylactic gastrostomy (PG) tube, while indication lacks harmonization. Our aim was to explore the current PG tube utilization among Belgian radiation oncology centers. METHODS: A survey was distributed to all 24 Belgian Radiation oncology departments, with questions about the number of patient treated per year, whether the PG indication is discussed at the multidisciplinary board, placement technique, time of starting nutrition and removal, its impact on swallowing function and importance of clinical factors. For the latter Relative Importance and Discordance Indexes were calculated to describe the ranking and agreement. RESULTS: All 24 centers submitted the questionnaire. Twenty three treat more than 20 head and neck (HNC) patients per year, while four (1 in 21-50; 3 in 51-100) are not discussing the gastrostomy tube indication at the multidisciplinary board. For the latter, endoscopic placement (68%) is the dominant technique, followed by the radiologic (16%) and laparoscopic (16%) methods. Seventy-five percent start the enteral nutrition when clinically indicated, 17% immediately and 8% from the start of radiotherapy. Majority of specialists (19/24) keep the gastrostomy tube until the patient assume an adequate oral feeding. Fifteen centres are considering PG decrease swallowing function. Regarding factors and their importance in the decision for the PG, foreseen irradiated volume reached highest importance, followed by 'anatomical site', 'patients' choice' and 'postoperative versus definitive' and 'local expertise', with decreasing importance respectively. Disagreement indexes showed moderate variation. CONCLUSIONS: The use of a PG tube for LAHNC patients treated by CCRT shows disparity at national level. Prospective studies are needed to ensure proper indication of this supportive measure.

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.

Efficacy of risk-reducing salpingo-oophorectomy in BRCA1-2 variants and clinical outcomes of follow-up in patients with isolated serous tubal intraepithelial carcinoma (STIC).

OBJECTIVE: Serous tubal intraepithelial carcinoma (STIC) is currently considered the precursor lesion of pelvic high-grade serous carcinoma. The management of STIC diagnosed after risk-reducing salpingo-oophorectomy (RRSO) in women with BRCA1-2 variants remains unclear. The aim of our study was to evaluate the incidence of STIC, serous tubal intraepithelial lesions (STIL) and occult invasive cancer (OC) and to determine the long-term outcomes of these patients. METHODS: We conducted a retrospective study of patients with BRCA 1-2 variants who underwent RRSO between January-2010 and Dicember-2020 at the Clinic of Gynaecology of University of Padova. INCLUSION CRITERIA: women with a negative pelvic examination at the last screening prior to RRSO, patients with fallopian tubes analysed using the SEE-FIM protocol. EXCLUSION CRITERIA: patients with a positive gynaecologic screening or with ovarian/tubal cancer prior to RRSO. RESULTS: We included 153 patients. STICs were diagnosed in 4 patients (2.6%) and STILs in 6 patients (3.9%). None of the patients with STIC underwent restaging surgery or adjuvant chemotherapy; all patients were followed closely every 6 months. None of the patients developed primary peritoneal carcinomas (PPCs) with a median FUP of 54.5 months (15-106). OC was diagnosed in 3 patients (2%). All patients with OC underwent staging surgery, and one patient developed a peritoneal carcinoma (PC) after 18 months by staging surgery. CONCLUSION(S): The incidence of STIC, STIL and OC after RRSO in BRCA1-2 variants was low. Our results demonstrated that long-term close surveillance in patients diagnosed with STIC should be considered a possible management strategy.

Uptake and timing of risk-reducing salpingo-oophorectomy among patients with BRCA1 and BRCA2 mutations.

BACKGROUND: In women with BRCA mutations, risk-reducing bilateral salpingo-oophorectomy has been shown to decrease gynecologic cancer-specific and overall mortality. The National Comprehensive Cancer Network recommends that patients with BRCA mutations undergo risk-reducing bilateral salpingo-oophorectomy between the ages of 35 and 40 years for BRCA1 mutation carriers and between the ages of 40 and 45 years for BRCA2 mutation carriers or after childbearing is complete. Currently, uptake and timing of risk-reducing bilateral salpingo-oophorectomy and reasons for delays in risk-reducing bilateral salpingo-oophorectomy are not well understood. OBJECTIVE: We sought to evaluate uptake and timing of risk-reducing bilateral salpingo-oophorectomy among women with BRCA1 and BRCA2 mutations concerning the National Comprehensive Cancer Network guidelines and reasons for delays in risk-reducing bilateral salpingo-oophorectomy. STUDY DESIGN: In this retrospective chart review, we identified women with BRCA1 and BRCA2 mutations who discussed risk-reducing bilateral salpingo-oophorectomy with a provider between 2012 and 2021. Uptake of risk-reducing bilateral salpingo-oophorectomy was documented, and patients were classified as having timely or delay in risk-reducing bilateral salpingo-oophorectomy based on the National Comprehensive Cancer Network guidelines. For those with delay in risk-reducing bilateral salpingo-oophorectomy, reasons cited for delay were collected. Comparative statistical analyses were performed to evaluate characteristics of those with timely vs delayed risk-reducing bilateral salpingo-oophorectomy. A multivariable logistic regression model was used to evaluate the associations among factors related to timing of risk-reducing bilateral salpingo-oophorectomy. RESULTS: We identified 638 BRCA1 and BRCA2 mutation carriers seen between 2012 and 2021. Of these patients, 306 (48.0%) had undergone risk-reducing bilateral salpingo-oophorectomy and 332 (52.0%) had not. When evaluating the timing of risk-reducing bilateral salpingo-oophorectomy, 136 (21.3%) underwent timely risk-reducing bilateral salpingo-oophorectomy, 239 (37.5%) had delays in risk-reducing bilateral salpingo-oophorectomy, and 263 (41.2%) had not undergone risk-reducing bilateral salpingo-oophorectomy but were younger than the National Comprehensive Cancer Network age guidelines; therefore, they were neither timely nor delayed. Patients with delay in risk-reducing bilateral salpingo-oophorectomy were significantly older at the time of genetic testing than those with timely risk-reducing bilateral salpingo-oophorectomy (mean, 49.8 vs 36.3 years; P<.001). Of the 306 patients who underwent risk-reducing bilateral salpingo-oophorectomy, those with delayed risk-reducing bilateral salpingo-oophorectomy had a significantly shorter interval between BRCA identification and risk-reducing bilateral salpingo-oophorectomy than those with timely risk-reducing bilateral salpingo-oophorectomy (median, 8.7 vs 17.6 months; P<.001). Patients with delay in risk-reducing bilateral salpingo-oophorectomy were more likely to have a personal history of cancer than those with timely risk-reducing bilateral salpingo-oophorectomy (49.8% vs 37.5%; P=.028). Of the 239 women with delay in risk-reducing bilateral salpingo-oophorectomy, 188 (78.7%) had delayed BRCA mutation identification, 29 (12.1%) had menopausal concerns, 17 (7.1%) had ongoing cancer treatment, 12 (5.0%) had coordination with breast surgery, 20 (8.4%) had miscellaneous reasons, and 19 (7.9%) had no reason documented. In the multivariate model, older age at BRCA diagnosis (odds ratio, 0.73; 95% confidence interval, 0.68-0.78; P<.001) was significantly associated with delayed risk-reducing bilateral salpingo-oophorectomy timing; those with BRCA2 mutation type were 7.54 times as likely to have timely risk-reducing bilateral salpingo-oophorectomy than BRCA1 mutation carriers (odds ratio, 7.54; 95% confidence, 3.70-16.42; P<.001). CONCLUSION: Nearly 38% of BRCA1 and BRCA2 mutation carriers undergo or have yet to undergo risk-reducing bilateral salpingo-oophorectomy over the recommended National Comprehensive Cancer Network age. The most common reason for the delay in risk-reducing bilateral salpingo-oophorectomy was delayed identification of BRCA mutation, noted in 79% of patients with delayed risk-reducing bilateral salpingo-oophorectomy. Timely genetic testing for eligible patients can increase appropriately timed risk-reducing bilateral salpingo-oophorectomy for the prevention of ovarian cancer and reduction of mortality in BRCA mutation carriers.

Prophylactic Central Neck Dissection in Papillary Thyroid Carcinoma: All Risks, No Reward.

BACKGROUND: Central neck dissection (CND) remains a controversial intervention for papillary thyroid carcinoma (PTC) patients with clinically negative nodes (cN0) in the central compartment. Proponents state that CND in cN0 patients prevents locoregional recurrence, while opponents deem that the risks of complications outweigh any potential benefit. Thus, there remains conflicting results amongst studies assessing oncologic and surgical outcomes in cN0 PTC patients who undergo CND. To provide clarity to this controversy, we sought to evaluate the efficacy, safety, and oncologic impact of CND in cN0 PTC patients at our institution. MATERIALS AND METHODS: Six hundred and ninety-five patients with PTC who underwent thyroidectomy at our institution between 1998 and 2018 were identified using an institutional cancer registry and supplemental electronic medical record queries. Patients were stratified by whether or not they underwent CND; identified as CND(+) or CND(-), respectively. Patients were also stratified by whether or not they received adjuvant radioactive iodine (RAI) therapy. Patient demographics, pathologic results, as well as surgical and oncologic outcomes were reviewed. Standard statistical analyses were performed using ANOVA and/or t-test and chi-squared tests as appropriate. RESULTS: Among the 695 patients with PTC, 492 (70.8%) had clinically and radiographically node negative disease (cN0). The mean age was 50 ± 1 years old and 368 (74.8%) were female. Of those with cN0 PTC, 61 patients (12.4%) underwent CND. CND(+) patients were found to have higher preoperative thyroid stimulating hormone (TSH) values, 2.8 ± 0.8 versus 1.5 ± 0.2 mU/L (P = 0.028) compared to CND(-) patients. CND did not significantly decrease disease recurrence, development of distant metastatic disease (P = 0.105) or persistence of disease (P = 0.069) at time of mean follow-up of 38 ± 3 months compared to CND(-) patients. However, surgical morbidity rates were significantly higher in CND(+) patients; including transient hypocalcemia (36.1% versus 14.4%; P < 0.001), transient recurrent laryngeal nerve (RLN) injury (19.7% vers us 7.0%; P < 0.001), and permanent RLN injury (3.3% versus 0.7%; P < 0.001). CONCLUSIONS: The majority of patients at our institution with cN0 PTC did not undergo CND. This data suggests that CND was not associated with improvements in oncologic outcomes during the short-term follow-up period and led to increased postoperative morbidity. Therefore, we conclude that CND should not be routinely performed for patients with cN0 PTC.

Effect of prophylactic balloon occlusion of internal iliac artery in pregnancies complicated by placenta previa and accreta.

BACKGROUND: Placenta previa and accreta are serious obstetric conditions that are associated with a high risk of intraoperative massive hemorrhage, the prophylactic intravascular balloon occlusion technique is increasingly used in managing uncontrolled hemorrhage in cesarean section (CS). We aim to examine the clinical effectiveness of prophylactic balloon occlusion of the internal iliac artery (PBOIIA) during CS in improving maternal outcomes for patients with placenta previa and accreta. METHODS: A total of 420 women with placenta previa and accreta who underwent CS from January 2014 to December 2018 were included retrospectively. Patients were divided into balloon group in which patients had PBOIIA (n = 248) and the control group in which patients did not have PBOIIA (n = 172). Meanwhile, we performed a subgroup analysis in whether taking parallel transverse uterine incision (PTUI) surgery. Information on conditions of patients and newborns, perioperative blood indicators, surgical outcomes were collected. RESULTS: Median estimated blood loss (mEBL) was 2200 mL in the balloon group and 2150 mL in the control group respectively, there was no significant difference between two-groups comparison (P > 0.05), and the rate of patients with hysterectomy was also has no difference between the two groups (36.3% verus 35.5%, P > 0.05), while there is a significant difference between two groups in the amount of PRBCs transfused [3 (0-31.5) verus 3 (0-39), P <0.05], moreover, the proportion of PRBCS> 8 units in the balloon group is significantly lower than that in control group (11.29% verus 23.26%, P <0.05).. However, the total hospitalization costs (45,624.4 ± 11,061.9 verus 37,523.1 ± 14,662.2, CYN) and surgery costs (19,910.6 ± 2622.6 verus 11,850.5 ± 3146.1, CYN) in balloon group were significantly higher than those in control group (P < 0.05). Subgroup analysis showed PTUI surgery had no significant differences in EBL (P >0.05), but it could significantly decrease hysterectomy rates (P <0.05). CONCLUSIONS: PBOIIA has no significant effect on reducing intraoperative EBL and hysterectomy rate in patients with placenta previa and accreta. and although it could reduce the intraoperative PRBCs in patients with massive hemorrhage, it significantly increases the financial cost for patients. Therefore, PBOIIA should not be routinely recommended to patients with placenta previa and accreta.

Prophylactic Ligature of AV Fistula Prevents High Output Heart Failure after Kidney Transplantation.

BACKGROUND: Arteriovenous (AV) fistulas are considered the gold standard for ensuring safe and long-term vascular access in patients with haemodialysis-dependent end-stage renal disease. However, previous studies demonstrated that high-flow AV fistulas might add additional cardiovascular burden in the post-transplant setting, leading to frequent fistula closure in this population. Currently, there is no consensus regarding management of high-flow fistulas in post-transplant patients with stable kidney function. The present randomized controlled trial examines the effect of prophylactic AV fistula closure on high-output heart failure. METHODS: Twenty-eight kidney transplant patients with stable graft function, absence of pre-existing severe cardiac failure, and brachial arterial flow rate of at least 1,500 mL/min were recruited and randomized in a 1:1 ratio to an intervention and control group, respectively. The intervention group was subject to immediate fistula ligature. Patients within the control group were referred to fistula ligature only if the main study endpoint high-output heart failure was reached. The latter was defined by the presence of at least 1 clinical sign (i.e., worsening NYHA score) and at least 2 of the following echocardiographic parameters: diameter of right atrium (major) >53 mm, right atrium (minor) >44 mm, inferior vena cava ≥21 mm, right pulmonary artery >20 mm, TAPSE <16 mm, systolic pulmonal artery pressure >40 mm Hg, and/or left ventricular eccentricity index <1. During a 24-month follow-up period, quarterly measurements of kidney function, NT-proBNP, and lactate dehydrogenase as well as a biannual echocardiographic check-up were performed. RESULTS: High-output heart failure attributable to high-flow fistula was reported in 5 of 13 control patients (38.5%), whereas no patient in the intervention group presented with clinical and echocardiographic signs of high-output heart failure during the follow-up period. Thus, prophylactic ligature of high-flow fistulas avoided high-output heart failure in our patient population (p = 0.013). Three patients in the control group, however, had to undergo fistula ligature due to aneurysm formation (n = 2) and steal phenomenon (n = 1). Median NT-proBNP levels decreased from 317 ng/L pre-ligature to 223 ng/L post-ligature (p = 0.003). Serum creatinine levels did not significantly differ before and after AV fistula ligature (1.69 vs. 1.60 mg/dL, respectively, p = 0.059). Improvement of echocardiographic findings (e.g., a decrease in systolic pulmonary arterial pressure) was found in 7 of 8 ligature patients but did not reach statistical significance. CONCLUSION: Prophylactic ligature of high-flow AV fistulas after kidney transplantation can avoid high-output heart failure, and a more liberal approach to close AV fistulas might be justified.

Mode of initial renal replacement therapy and transplant outcomes in the chronic kidney disease in children (CKiD) study.

BACKGROUND: Kidney transplant is the renal replacement therapy (RRT) of choice for children with end stage kidney disease (ESKD). Only 21.3% of children who initiate RRT receive a preemptive kidney transplant (PKT). We characterized the transition to RRT in children in the CKiD cohort including the prevalence of dialysis as first RRT vs. PKT and graft survival. METHODS: 258 children enrolled in CKiD have initiated RRT, and 202 had post-RRT initiation data collected through phone or in-person follow-up. Characteristics by first RRT modality were compared using Chi-square and Kruskal-Wallis tests. Parametric-accelerated failure time models were fit for transplantation. Graft failure was characterized using Kaplan-Meier methods and log rank tests. RESULTS: Sixty-one percent received dialysis as first RRT modality and 39% PKT. Those with PKT were less likely to have glomerular disease and to be African-American, and had higher household-income. African-American subjects were nearly twice as likely to undergo dialysis prior to transplant. Those with a living donor and a college-educated mother had 40%-decreased odds of being dialysis experienced. Children with PKT were more likely to receive a living donor transplant. Only 5% of PKT subjects had graft failure by 4 years compared to 16% of those initially treated with dialysis (p = 0.092); however, after adjustment the effect of dialysis exposure was attenuated (p = 0.206). CONCLUSION: CKiD subjects undergo PKT more often compared to nationally-reported rates, and are more likely to receive a kidney transplant within 1 year of starting dialysis. African-American race and lower household-income are associated with decreased access to PKT.

Long-term outcomes following a diagnosis of ovarian cancer at the time of preventive oophorectomy among BRCA1 and BRCA2 mutation carriers.

INTRODUCTION: Preventive bilateral salpingo-oophorectomy is the most effective means of reducing the risk of ovarian cancer among women with an inherited BRCA1 or BRCA2 mutation. Some women are diagnosed with an invasive cancer (ovarian or fallopian tube) at the time of preventive surgery, referred to as an 'occult' cancer. The survival experience of these women is not known. METHODS: We estimated the 10-year survival for 52 BRCA mutation carriers diagnosed with an occult ovarian or fallopian tube cancer at the time of preventive bilateral salpingo-oophorectomy. RESULTS: The mean age at diagnosis was 51.6 (range 33-69) years. All were serous cancers (although 14 were missing information on histologic subtype). Of the 20 cases with information available on stage at diagnosis, 10 were stage I, 1 was stage II, and 9 were stage III (n=32 missing). After a mean of 6.8 years, 12 women died (23%). The 10-year all-cause survival was 74%. CONCLUSION: Although based on only 52 cases, these findings suggest a more favorable prognosis for BRCA mutation carriers diagnosed with an occult rather than incident disease.

Risk-reducing Bilateral Salpingo-oophorectomy: Assessing the Incidence of Occult Ovarian Cancer and Surgeon Adherence to Recommended Practices.

STUDY OBJECTIVE: This study aimed to determine the incidence of ovarian cancer diagnosed at the time of risk-reducing bilateral salpingo-oophorectomy in a large cohort of patients with a BRCA mutation. In addition, we aimed to determine the adherence to the recommended practices for performing a risk-reducing bilateral salpingo-oophorectomy as described by the American College of Obstetricians and Gynecologists and the Society of Gynecologic Oncology. We sought to determine if adherence differed by the type of training (i.e., gynecologic oncologists vs benign gynecologists). DESIGN: Descriptive, retrospective analysis. SETTING: Academic medical center. PATIENTS: Two hundred sixty-nine patients with a known BRCA mutation. INTERVENTIONS: Prophylactic risk-reducing bilateral salpingo-oophorectomy performed either by a gynecologic oncologist or a benign gynecologist between July 2007 and September 2018. MEASUREMENTS AND MAIN RESULTS: Among 269 patients who underwent risk-reducing bilateral salpingo-oophorectomies, 220 procedures were performed by gynecologic oncologists, and 49 were performed by benign gynecologists. Washings were not performed in 5% of the procedures performed by gynecologic oncologists and 37% of the procedures performed by benign gynecologists (p <.001). Complete serial sectioning of the adnexa was not performed in 12% of the procedures performed by oncologists, and 13% of the procedures performed by benign gynecologists (p = .714). There were 8 cases (2.9%) of tubal or ovarian cancer diagnosed within this cohort. Of these cases, only 3 (1.1%) were diagnosed at the time of surgery and met the criteria for conversion to a staging procedure. CONCLUSION: Because the incidence of ovarian cancer diagnosis at the time of risk-reducing bilateral salpingo-oophorectomy is low and is often not diagnosed at the time of surgery owing to the presence of only microscopic disease, it may not be necessary for gynecologic oncologists to exclusively perform these procedures. However, this study also revealed that when this procedure is performed by benign gynecologic surgeons, some of the recommended practices are not routinely followed. If general gynecologic surgeons are to routinely perform risk-reducing bilateral salpingo-oophorectomies, it is important to promote better adherence to these practices.

Preoperative Prophylactic Balloon-Assisted Occlusion of the Internal Iliac Arteries in the Management of Placenta Increta/Percreta.

Background and Objectives: Preoperative prophylactic balloon-assisted occlusion (PBAO) of the internal iliac arteries minimizes blood loss and facilitates surgery performance, through reductions in the rate of uterine perfusion, which allow for better control in hysterectomy performance, with decreased rates of bleeding and surgical complications. We aimed to investigate the maternal and fetal outcomes associated with PBAO use in women with placenta increta or percreta. Material and Methods: The records of 42 consecutive patients with a diagnosis of placenta increta or percreta were retrospectively reviewed. Of 42 patients, 17 patients (40.5%) with placenta increta or percreta underwent cesarean delivery after prophylactic balloon catheter placement in the bilateral internal iliac artery (balloon group). The blood loss volume, transfusion volume, postoperative hemoglobin changes, rates of hysterectomy and hospitalization, and infant Apgar score in this group were compared to those of 25 similar women who underwent cesarean delivery without balloon placement (surgical group). Results: The mean intraoperative blood loss volume in the balloon group (2319 ± 1191 mL, range 1000-4500 mL) was significantly lower than that in the surgical group (4435 ± 1376 mL, range 1500-10,500 mL) (p = 0.037). The mean blood unit volume transfused in the balloon group (2060 ± 1154 mL, range 1200-8000 mL) was significantly lower than that in the surgical group (3840 ± 1464 mL, range 1800-15,200 mL) (p = 0.043). There was no significant difference in the postoperative hemoglobin change, hysterectomy rates, length of hospitalization, or infant Apgar score between the groups. Conclusion: PBAO of the internal iliac artery prior to cesarean delivery in patients with placenta increta or percreta is a safe and minimally invasive technique that reduces the rate of intraoperative blood loss and transfusion requirements.

Survey of pelvic reconstructive surgeons on performance of opportunistic salpingectomy at the time of pelvic organ prolapse repair.

INTRODUCTION AND HYPOTHESIS: Opportunistic salpingectomy (OS) at the time of benign hysterectomy has recently emerged as a potential primary preventive modality for ovarian cancer. Our objective was to determine whether the reported rate of OS at the time of prolapse surgery is similar to the rate of OS at the time of gynecologic surgery for non-prolapse indications. METHODS: An anonymous online survey was sent to the Society of Gynecologic Surgery members. Responses were divided into surgeons who did and did not perform OS at the time of prolapse repair. Differences between surgeons who did and did not perform OS were evaluated using the chi-square test. Multivariable logistic regression was used to identify which responses related to increased odds of performing OS. RESULTS: There were 117 (33.1%) completed responses; of these, 98 (83.8%) reported performing OS at the time of prolapse repair, which was similar to the reported rate of OS at the time of hysterectomy for non-prolapse indications, 82.1%. After multivariable logistic regression, performance of salpingectomy at the time of hysterectomy for a non-prolapse indication (aOR: 17.9, 95% CI: 3.11-42.01), use of a laparoscopic or robotic surgical approach (aOR 14.1, 95% CI: 1.81-32.21) and completion of an FPMRS fellowship (aOR: 3.47, 95% CI: 1.20-10.02) were associated with a higher likelihood of performing OS at the time of prolapse repair. CONCLUSIONS: OS at the time prolapse repair is performed more frequently with concomitant hysterectomy compared with OS at the time of post-hysterectomy prolapse repair and is similar to rates of OS performed at the time of hysterectomy for non-prolapse indications.

Web-Based Model for Predicting Time to Surgery in Young Patients with Familial Adenomatous Polyposis: An Internally Validated Study.

INTRODUCTION: The timing of prophylactic colorectal surgery in patients with familial adenomatous polyposis (FAP) is based on the immediacy of the colorectal cancer risk. The ability to predict the need for surgery may help patients and their families plan in the context of life events and CRC risk. We created a model to predict the likelihood of surgery within 2 and 5 years of first colonoscopy at our institution. METHODS: A single institution hereditary colorectal syndrome (Cologene™) database was interrogated for all patients with FAP having a deleterious APC mutation. Patients with first colonoscopy after age 30 and before year 2000 were excluded. Cox regression analysis was done to assess multiple factors associated with surgery, followed by stepwise Cox regression analysis to select an optimal model. Receiver operator curve (ROC) analysis was performed to assess the model. RESULTS: A total of 211 (53% female) patients were included. Forty-five percent underwent surgery after an average of 3.8 years of surveillance. The final model was created based on initial clinical characteristics (age, gender, BMI, family history of desmoids, genotype-phenotype correlation), initial colonoscopic characteristics (number of polyps, polyp size, presence of high-grade dysplasia); and on clinical events (chemoprevention and polypectomy). AUC was 0.87 and 0.84 to predict surgery within 2 and 5 years, respectively. The final model can be accessed at this website: http://app.calculoid.com/#/calculator/29638 . CONCLUSION: This web-based tool allows clinicians to stratify patients' likelihood of colorectal surgery within 2 and 5 years of their initial examination, based on clinical and endoscopic features, and using the philosophy of care guiding practice at this institution.

Bone loss in women with BRCA1 and BRCA2 mutations.

OBJECTIVE: Estimate the prevalence and identify risk factors for bone loss in women with BRCA mutations. METHODS: Women, age 40 and older, with BRCA mutations identified from the Breast Cancer Surveillance database at Kaiser Permanente Northern California were invited to participate and undergo a dual-energy x-ray absorptiometry scan to assess for bone loss (osteopenia or osteoporosis). Multivariable logistic regression analysis was performed to assess clinical factors associated with bone loss. RESULTS: Of the 238 women in the final cohort, 20 women had intact ovaries (median age 54.5years) and 218 had undergone risk reducing salpingo-oophorectomy (RRSO) (median age 57). The prevalence of bone loss was 55% in the no RRSO group and 72.5% in the RRSO group (P=0.10). In multivariable analysis, only higher body mass index (OR 0.6 per 5kg/m2, 95% CI: 0.4-0.7) and nonwhite race compared to white (OR 0.5, 95% CI: 0.2-0.9) were protective for bone loss while older age (OR 1.5 per 10years, 95% CI: 1.1-2.1) and selective estrogen receptor modulator use (3.1, 95% CI: 1.2-10.1) were associated with increased odds of bone loss. Among women with RRSO, bone loss was more frequent in women who had postmenopausal (n=106) compared to women who had premenopausal RRSO (n=112), (82.1% and 63.4% respectively, P=0.002). In multivariable analysis, only BMI was protective of bone loss (OR 0.5, 95%, CI: 0.4-0.7) but neither age nor menopausal status at RRSO were associated with bone loss. CONCLUSION: Bone loss is common in women with BRCA mutations who undergo RRSO.

The Use of Opportunistic Salpingectomy at the Time of Benign Hysterectomy.

STUDY OBJECTIVE: To delineate the use of opportunistic salpingectomy over the study period, to examine factors associated with its use, and to evaluate whether salpingectomy was associated with perioperative complications. DESIGN: A retrospective cross-sectional study (Canadian Task Force classification II-2). SETTING: The Michigan Surgical Quality Collaborative. PATIENTS: Women undergoing ovarian-conserving hysterectomy for benign indications from January 2013 through April 2015. INTERVENTIONS: The primary outcome was the performance of opportunistic salpingectomy with ovarian preservation during benign hysterectomy. The change in the rate of salpingectomy was examined at 4-month intervals to assess a period effect over the study period. Multivariate logistic regression was performed to evaluate independent effects of patient, operative, and period factors. Perioperative outcomes were compared using propensity score matching. MEASUREMENTS AND MAIN RESULTS: There were 10 676 (55.9%) ovarian-conserving hysterectomies among 19 090 benign hysterectomies in the Michigan Surgical Quality Collaborative in the study period. The rate of opportunistic salpingectomy was 45.8% (n = 4890). Rates of opportunistic salpingectomy increased over the study period from 27.5% to 61.6% (p < .001), demonstrating a strong period effect in the consecutive 4-month period analysis. Salpingectomy was more likely with the laparoscopic approach (odds ratio = 3.48; 95% confidence interval, 3.15-3.85) and among women younger than 60 years of age (odds ratio = 1.60; 95% CI, 1.34-1.92). There was substantial variation in salpingectomy across hospital sites, ranging from 3.6% to 79.9%. Salpingectomy was associated with a 12-minute increase in operative time (p < .001), but there were no differences in the estimated blood loss or perioperative complications. CONCLUSION: The rates of salpingectomy increased significantly over the study period. The laparoscopic approach and younger age are associated with an increased probability of salpingectomy. Salpingectomy is not associated with increased blood loss or perioperative complications.

Surgical Findings and Outcomes in Premenopausal Breast Cancer Patients Undergoing Oophorectomy: A Multicenter Review From the Society of Gynecologic Surgeons Fellows Pelvic Research Network.

STUDY OBJECTIVE: To describe the procedures performed, intra-abdominal findings, and surgical pathology in a cohort of women with premenopausal breast cancer who underwent oopherectomy. DESIGN: Multicenter retrospective chart review (Canadian Task Force classification II-3). SETTING: Nine US academic medical centers participating in the Fellows' Pelvic Research Network (FPRN). PATIENTS: One hundred twenty-seven women with premenopausal breast cancer undergoing oophorectomy between January 2013 and March 2016. INTERVENTION: Surgical castration. MEASUREMENTS AND MAIN RESULTS: The mean patient age was 45.8 years. Fourteen patients (11%) carried a BRCA mutations, and 22 (17%) carried another germline or acquired mutation, including multiple variants of uncertain significance. There was wide variation in surgical approach. Sixty-five patients (51%) underwent pelvic washings, and 43 (35%) underwent concurrent hysterectomy. Other concomitant procedures included midurethral sling placement, appendectomy, and hysteroscopy. Three patients experienced complications (transfusion, wound cellulitis, and vaginal cuff dehiscence). Thirteen patients (10%) had ovarian pathology detected on analysis of the surgical specimen, including metastatic tumor, serous cystadenomas, endometriomas, and Brenner tumor. Eight patients (6%) had Fallopian tube pathology, including 3 serous tubal intraepithelial cancers. Among the 44 uterine specimens, 1 endometrial adenocarcinoma and 1 multifocal endometrial intraepithelial neoplasia were noted. Regarding the entire study population, the number of patients meeting our study criteria and seen by gynecologic surgeons in the FPRN for oophorectomy increased by nearly 400% from 2013 to 2015. CONCLUSION: Since publication of the Suppression of Ovarian Function Trial data, bilateral oophorectomy has been recommended for some women with premenopausal breast cancer to facilitate breast cancer treatment with aromatase inhibitors. These women may be at elevated risk for occult abdominal pathology compared with the general population. Gynecologic surgeons often perform castration oophorectomy in patients with breast cancer as an increasing number of oncologists are using aromatase inhibitors to treat premenopausal breast cancer. Our data suggest that other abdominal/pelvic cancers, precancerous conditions, and previously unrecognized metastatic disease are not uncommon findings in this patient population. Gynecologists serving this patient population may consider a careful abdominal survey, pelvic washings, endometrial sampling, and serial sectioning of fallopian tube specimens for a thorough evaluation.

Racial disparities in BRCA testing and cancer risk management across a population-based sample of young breast cancer survivors.

BACKGROUND: Breast cancer (BC) disparities may widen with genomic advances. The authors compared non-Hispanic white (NHW), black, and Hispanic BC survivors for 1) cancer risk-management practices among BRCA carriers and 2) provider discussion and receipt of genetic testing. METHODS: A population-based sample of NHW, black, and Hispanic women who had been diagnosed with invasive BC at age 50 years or younger from 2009 to 2012 were recruited through the state cancer registry. Multiple logistic regression was used to compare cancer risk-management practices in BRCA carriers and associations of demographic and clinical variables with provider discussion and receipt of testing. RESULTS: Of 1622 participants, 159 of 440 (36.1%) black women, 579 of 897 (64.5%) NHW women, 58 of 117 (49.6%) Spanish-speaking Hispanic women, and 116 of 168 (69%) English-speaking Hispanic women underwent BRCA testing, of whom 90 had a pathogenic BRCA mutation identified. Among BRCA carriers, the rates of risk-reducing mastectomy and risk-reducing salpingo-oophorectomy were significantly lower among black women compared with Hispanic and NHW women after controlling for clinical and demographic variables (P = .025 and P = .008, respectively). Compared with NHW women, discussion of genetic testing with a provider was 16 times less likely among black women (P < .0001) and nearly 2 times less likely among Spanish-speaking Hispanic women (P = .04) after controlling for clinical and sociodemographic factors. CONCLUSIONS: The current results suggest that the rates of risk-reducing salpingo-oophorectomy are lower among black BRCA carriers compared with their Hispanic and NHW counterparts, which is concerning because benefits from genetic testing arise from cancer risk-management practice options. Furthermore, lower BRCA testing rates among blacks may partially be because of a lower likelihood of provider discussion. Future studies are needed to improve cancer risk identification and management practices across all populations to prevent the widening of disparities.

Assessing the Risk of Occult Cancer and 30-day Morbidity in Women Undergoing Risk-reducing Surgery: A Prospective Experience.

STUDY OBJECTIVE: To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. DESIGN: A prospective study (Canadian Task Force classification II-1). SETTING: A gynecologic oncology referral center. PATIENTS: Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). INTERVENTIONS: Minimally invasive risk-reduction surgery. MEASUREMENTS AND MAIN RESULTS: Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). CONCLUSION: Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery.

Severity of Asynchronous Slipped Capital Femoral Epiphyses in Skeletally Immature Versus More Skeletally Mature Patients.

BACKGROUND: Routine prophylactic screw fixation for skeletally immature patients with slipped capital femoral epiphysis (SCFE) continues to be debated. The purpose of this study was to assess the slip severity of a second SCFE in skeletally immature versus more mature patients and determine necessity of contralateral hip prophylactic screw fixation. METHODS: All patients treated for SCFE at 3 pediatric hospitals over a 10-year time period (January 1, 2002 to December 31, 2011) were evaluated. Patients were included if they had a unilateral SCFE and a contralateral asynchronous SCFE, and were divided into immature (Oxford triradiate score 1) versus more mature (Oxford triradiate score 2 and 3) groups. Data evaluation included age, time between slips, body mass index, Southwick angles of first then second SCFEs, and follow-up duration. RESULTS: There were a total of 45 patients: 16 patients in the skeletally immature and 29 patients in the more mature group. Average age at first SCFE in immature patients was 10.9 years and in more mature patients 12.1 years (P=0.70). Age at second SCFE in immature patients was 11.5 years and in more mature patients 13.0 years (P=0.023). Average time between SCFEs was 6.6 months for immature and 11.4 months for more mature patients (P=0.093). Southwick angles for immature patient first and second SCFEs were 25 and 12.9 degrees, respectively, and for more mature patient first and second SCFEs were 31 and 21 degrees, respectively. Southwick angles were higher at first and second slips in the more mature group, significant only at the second slip (P=0.032). SCFE severity at initial event was predictive of severity of second SCFE regardless of maturity (P=0.043). Regression analysis of slip severity against multiple patient factors demonstrated triradiate score was not a factor assessing subsequent SCFE magnitude (P=0.099). CONCLUSIONS: There was no significant difference between first and second SCFEs regardless of skeletal maturity but severity of initial SCFE did correlate with severity of the second SCFE. Deciding not to prophylactically pin an unaffected hip does not lead to worse deformity if a second SCFE occurs in skeletally immature or more mature patients, unless the initial event is severe. Prophylactic pin fixation in skeletally immature patients should occur as a shared decision between patient, guardians, and treating surgeon. LEVEL OF EVIDENCE: Level III-retrospective comparative study.
