Points to consider regarding prophylactic total gastrectomy in germline CDH1 variant carriers. J Surg Oncol 2024; 129:1082-1088. [PMID: 38389278 DOI: 10.1002/jso.27603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 02/06/2024] [Indexed: 02/24/2024]
Abstract
Pathogenic germline CDH1 mutation confers high risk for developing diffuse gastric and lobular breast cancers in asymptomatic carriers. In these individuals, the estimated gastric cancer risk at 80 years of age is up to 70% for males and 56% for females. Due to this high-risk predisposition, prophylactic total gastrectomy is considered a unique life-saving approach in germline CDH1 carriers, as endoscopy often fails to detect early stage diffuse gastric carcinoma. However, surgical indication is controversial in some clinical contexts, with possible contraindications. This review discusses points against and in favor of a more aggressive surgical approach for consideration during the decision-making process.

Combined Bilateral Salpingo-oophorectomy and Cesarean Delivery in BRCA1/2 Alteration Carriers : A Case Series. Obstet Gynecol 2023; 142:1500-1503. [PMID: 37917945 PMCID: PMC10642698 DOI: 10.1097/aog.0000000000005423] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 08/02/2023] [Accepted: 08/23/2023] [Indexed: 11/04/2023]
Abstract
BACKGROUND The cumulative lifetime risk of ovarian cancer is 16-68% and 11-30% in female BRCA1 and BRCA2 gene alteration carriers, respectively. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is the only proven way to reduce ovarian cancer mortality. We report a series of patients who underwent risk-reducing surgery at the time of planned obstetric-indicated cesarean delivery. CASES This is a case series of four women carrying a pathogenic germline BRCA1 or BRCA2 gene alteration who underwent RRSO at the time of cesarean delivery between March 1, 2018, and March 31, 2022. All women were referred during pregnancy to the University College London Hospitals Familial Cancer Clinic for consideration of RRSO at the time of obstetric-indicated cesarean delivery. Women were considered eligible for RRSO if they had a proven pathogenic germline alteration, would have completed childbearing after the cesarean delivery, and were older than age 35 or 40 years with BRCA1 or BRCA2 alterations, respectively. Operating time, blood loss, transfusion requirements, length of hospital stay, complications, and ability to breastfeed were assessed and, where possible, compared with the institutional means for similar patients who underwent cesarean delivery only, to determine whether RRSO was associated with increased morbidity. Women were contacted 11-59 months postprocedure to assess satisfaction. The mean blood loss was 687 mL (range 400-1,000 mL), mean operating time was 68 minutes, mean length of hospital stay was 3 days, and mean change in hemoglobin was -1 g/dL. No patient required a transfusion, had internal organ damage, returned to the operating room, or was readmitted. One of two women with intact breast tissue successfully breastfed, and the other chose to bottle feed. The mean contemporaneous institutional blood loss for cesarean delivery was not significantly different at 681 mL for singleton pregnancies and 872 mL for twin pregnancies. All four women reported a high level of satisfaction with the combined procedure. CONCLUSION Our results show that RRSO can be performed at the time of cesarean delivery with high patient satisfaction. This approach can be offered to appropriately counseled individuals, with the benefit of avoiding the need for two separate procedures, with potentially reduced patient morbidity and health care costs.

The effect of prophylactic bilateral salpingectomy on ovarian reserve in patients who underwent laparoscopic hysterectomy. J Ovarian Res 2021; 14:86. [PMID: 34187523 PMCID: PMC8243536 DOI: 10.1186/s13048-021-00825-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 05/12/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Bilateral salpingectomy has been proposed to reduce the risk of ovarian cancer, but it is not clear whether the surgery affects ovarian reserve. This study compares the impact of laparoscopic hysterectomy for benign disease with or without prophylactic bilateral salpingectomy on ovarian reserve. METHODS Records were reviewed for 373 premenopausal women who underwent laparoscopic hysterectomy with ovarian reserve for benign uterine diseases. The serum anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and three-dimensional antral follicle count (AFC) were assessed before surgery and 3 and 9 months postoperatively to evaluate ovarian reserve. Patients were divided into two groups according to whether they underwent prophylactic bilateral salpingectomy. The incidence of pelvic diseases was monitored until the ninth month after surgery. RESULTS There was no significant difference between the two surgery groups in terms of baseline AMH, E2, FSH, LH, and AFC (all P > 0.05). There was no difference in potential bias factors, including patient age, operative time, and blood loss (all P > 0.05). There was also no significant difference between the two groups 3 months after surgery with respect to AMH (P = 0.763), E2 (P = 0.264), FSH (P = 0.478), LH (P = 0.07), and AFC (P = 0.061). Similarly, there were no differences between groups 9 months after surgery for AMH (P = 0.939), E2 (P = 0.137), FSH (P = 0.276), LH (P = 0.07) and AFC (P = 0.066). At 9 months after the operation, no patients had malignant ovarian tumors. The incidences of benign ovarian tumors in the salpingectomy group were 0 and 2.68 % at 3 and 9 months after surgery, respectively, and the corresponding values in the control group were 0 and 5.36 %. The incidences of pelvic inflammatory disease in the salpingectomy group were 10.72 and 8.04 % at 3 and 9 months after surgery, respectively, while corresponding values in the control group were 24.13 and 16.09 %. CONCLUSIONS Prophylactic bilateral salpingectomy did not damage the ovarian reserve of reproductive-age women who underwent laparoscopic hysterectomy. Prophylactic bilateral salpingectomy might be a good method to prevent the development of ovarian cancer. Larger clinical trials with longer follow-up times are needed to further evaluate the risks and benefits.

Abstract
BACKGROUND Marfan syndrome is an inherited connective tissue disease that causes aortic root dilatation and dissection and requires surgical intervention. Apart from emergent surgery for aortic dissection or aortic aneurysmal rupture, prophylactic surgical intervention can also be administered, depending on the severity of aortic root dilatation. The direct relationship between surgical intervention and aortic regurgitation was seldom mentioned in previous studies. METHODS A retrospective cohort study was designed to determine the clinical presentations of prophylactic surgery in patients with Marfan syndrome. Between January 2009 and May 2019, 112 patients, adolescents and young adults, treated in the Department of Pediatric Cardiology of Taipei Veterans General Hospital, were enrolled. All patients' sex, body measurements, echocardiography reports, and surgical notes were collected for statistical analysis. RESULTS Among the participants, nine patients (8%) underwent the Bentall procedure, and the other 103 did not receive surgical intervention. The operation group had a larger aortic root size (4.89 vs 2.86 cm, p < 0.001), more dilated left ventricle (4.81 vs 4.1 cm, p = 0.002), and higher prevalence of moderate and severe aortic regurgitation (66% vs 1%, p < 0.001) than the nonoperation group. CONCLUSION Among adolescents and young adults with Marfan syndrome, echocardiographic presentation of aortic root dilatation, left ventricular dilatation, and significant aortic regurgitation was significantly associated with prophylactic surgical intervention. According to the study, significant aortic regurgitation should also be considered as an important indication for prophylactic surgery.

Abstract
BACKGROUND The preoperative distinguishment of lymph nodes with reactive hyperplasia or tumor metastasis plays a pivotal role in guiding the surgical extension for papillary thyroid carcinoma (PTC) with Hashimoto's thyroiditis (HT), especially in terms of the central lymph node (CLN) dissection. We aim to identify the preparative risk factors for CLN metastasis in PTC patients concurrent with HT. MATERIALS AND METHODS We retrospectively reviewed and analyzed the data including the basic information, preoperative sonographic characteristics, and thyroid function of consecutive PTC patients with HT in our medical center between Jan 2019 and Apr 2021. The Chi-square and Fisher's exact tests were used for comparison of qualitative variables among patients with or without CLN metastasis. Univariate and multivariate logistic regression analyses were used to determine the risk factors for CLN metastasis. The nomogram was constructed and further evaluated by two cohorts produced by 1,000 resampling bootstrap analysis. RESULTS A total of 98 in 214 (45.8%) PTC patients were identified with CLN metastasis. In multivariate analysis, four variables including high serum thyroglobulin antibody (TgAb) level (>1,150 IU/ml), lower tumor location, irregular margin of CLN, and micro-calcification in the CLN were determined to be significantly associated with the CLN metastasis in PTC patients with HT. An individualized nomogram was consequently established with a favorable C-index of 0.815 and verified via two internal validation cohorts. CONCLUSIONS Our results indicated that preoperatively sonographic characteristics of the tumor and lymph node condition combined with serum TgAb level can significantly predict the CLN in PTC patients with HT and the novel nomogram may further help surgeons to manage the CLN in this subpopulation.

Abstract
To analyze possible clinical-pathological parameters and predictors of lymph node metastasis and evaluate the impact of lymphadenectomy in the survival of these patients.A retrospective study of patients diagnosed with penile cancer and submitted to regional lymphadenectomy at two reference hospitals in Maranhão, Northeast, Brazil, an area where the disease has a high incidence. We described here clinical and histopathological characteristics of patients diagnosed between January 2009 and September 2017.Fifty-five patients with an average age of 55.4 years (range: 25-84 years) were analyzed, with 24.4 months being the average time between the onset of symptoms and start of treatment. Among patients without palpable lymph nodes at the first examination, 51% were affected by inguinal metastasis. In the multivariate analysis, the presence of angiolymphatic invasion (P = .029) and absence of koilocytosis (P = .001) were found to be predictive factors for lymph node metastasis. Patients submitted to prophylactic lymphadenectomy presented with a disease-free period of 25.4 months (±5.81), whereas those who underwent therapeutic lymphadenectomy presented with a disease-free period of 19.9 months (±3.12).Angiolymphatic invasion and absence of koilocytosis appeared to be predictive factors for lymph node metastasis. Therefore, the submission of patients with metastatic risk to prophylactic lymphadenectomy may improve their survival. Thus, prophylactic lymphadenectomy in patients at risk for inguinal metastasis may create a positive impact in survival rates.

Abstract
Left polyorchidism was found in a 2-month-old boy with a left scrotal mass. As he was asymptomatic and all testes were in the scrotum, he was conservatively followed up. At 17 years of age, he presented with left acute scrotum due to testicular torsion of the left supernumerary testis. Counterclockwise 720-degree rotation of the left supernumerary testis was noted during emergency surgery, and orchidopexy of the 3 testes (2 left testes and 1 right testis) was performed. Biopsy of the left supernumerary testis demonstrated spermatogenesis and no malignancy. One and a half years after surgery, all testes were viable without atrophy.Polyorchidism is a rare condition and there is no consensus on the management of asymptomatic cases detected early in life. The position of the supernumerary testis (intrascrotal or extrascrotal) is important when deciding the management strategy because of the risk of malignancy. If conservative management is selected initially, elective surgery, such as prophylactic orchiectomy or orchidopexy, may be needed because of the risk of malignancy and torsion.

Increased complications without neurological benefit are associated with prophylactic spinal cord untethering prior to scoliosis surgery in children with myelomeningocele. Childs Nerv Syst 2019; 35:2187-2194.

Abstract
PURPOSE Children with myelomeningocele (MMC) are at increased risk of developing neuromuscular scoliosis and spinal cord re-tethering (Childs Nerv Syst 12:748-754, 1996; Neurosurg Focus 16:2, 2004; Neurosurg Focus 29:1, 2010). Some centers perform prophylactic untethering on asymptomatic MMC patients prior to scoliosis surgery because of concern that additional traction on the cord may place the patient at greater risk of neurologic deterioration peri-operatively. However, prophylactic untethering may not be justified if it carries increased surgical risks. The purpose of this study was to determine if prophylactic untethering is necessary in asymptomatic children with MMC undergoing scoliosis surgery. METHODS A multidisciplinary, retrospective cohort study from seven children's hospitals was performed including asymptomatic children with MMC < 21 years old, managed with or without prophylactic untethering prior to scoliosis surgery. Patients were divided into three groups for analysis: (1) untethering at the time of scoliosis surgery (concomitant untethering), (2) untethering within 3 months of scoliosis surgery (prior untethering), and (3) no prophylactic untethering. Baseline data, intra-operative reports, and 90-day post-operative outcomes were analyzed to assess for differences in neurologic outcomes, surgical complications, and overall length of stay. RESULTS A total of 208 patients were included for analysis (mean age 9.4 years, 52% girls). No patient in any of the groups exhibited worsened motor or sensory function at 90 days post-operatively. However, comparing the prophylactic untethering groups with the group that was not untethered, there was an increased risk of surgical site infection (SSI) (31.3% concomitant, 28.6% prior untethering vs. 12.3% no untethering; p = 0.0104), return to the OR (43.8% concomitant, 23.8% prior untethering vs. 17.4% no untethering; p = 0.0047), need for blood transfusion (51.6% concomitant, 57.1% prior untethering vs. 33.8% no untethering; p = 0.04), and increased mean length of stay (LOS) (13.4 days concomitant, 10.6 days prior untethering vs. 6.8 days no untethering; p < 0.0001). In multivariable logistic regression analysis, prophylactic untethering was independently associated with increased adjusted relative risks of surgical site infection (aRR = 2.65, 95% CI 1.17-5.02), unplanned re-operation (aRR = 2.17, 95% CI 1.02-4.65), and any complication (aRR = 2.25, 95% CI 1.07-4.74). CONCLUSION In this study, asymptomatic children with myelomeningocele who underwent scoliosis surgery developed no neurologic injuries regardless of prophylactic untethering. However, those who underwent prophylactic untethering were more likely to experience SSIs, return to the OR, need a blood transfusion, and have increased LOS than children not undergoing untethering. Based on these data, prophylactic untethering in asymptomatic MMC patients prior to scoliosis surgery does not provide any neurological benefit and is associated with increased surgical risks.

Abstract
BACKGROUND Lynch syndrome, or hereditary nonpolyposis colorectal cancer, is an autosomal dominant genetic syndrome that predisposes individuals to multiple cancer types. The known cancers associated with Lynch syndrome include colorectal and endometrial cancers as well as cancers of the stomach, ovary, urinary tract, hepatobiliary tract, pancreas, small bowel, and brain. There are no searchable cases of malignant phyllodes of the breast associated with Lynch syndrome. CASE PRESENTATION Our patient was a 43-year-old Caucasian woman who felt a lump in her left breast and was found to have a spindle cell neoplasm. Definitive surgery revealed a malignant phyllodes tumor. On the basis of her cancer diagnosis and family history of multiple cancers, a Myriad myRisk Hereditary Cancer® test panel of 25 genes was performed. This testing revealed that she had a heterozygous MSH6 mutation as part of the Lynch syndrome panel. Due to positive margins, the patient received adjuvant chemotherapy with doxorubicin and ifosfamide. She also had a subsequent total abdominal hysterectomy and a bilateral salpingo-oophorectomy for risk reduction. She remains in a high-risk surveillance program. Her family members have been tested, which revealed that her two brothers and daughter also carry the genetic mutation. CONCLUSIONS This case highlights the importance of genetic testing with rare malignancies because the full scope of phenotypic sequelae for known hereditary syndromes has not been mapped.

Abstract
BACKGROUND Gastric cancer is the fifth most prevalent and the third most lethal cancer worldwide, causing approximately 720,000 deaths annually. Although most cases of gastric cancers are sporadic, one of its inherited forms, hereditary diffuse gastric cancer (HDGC), constitutes about 1-3% of cases. Interestingly, females in families with HDGC are also predisposed to developing lobular breast cancer (LBC). Recent analyses have identified loss-of-function germline mutations in cadherein-1 (CDH1) as a culprit in HDGC and LBC. This discovery fueled several sequencing analyses and case series reports analyzing the pattern of inheritance of CDH1 and its propensity to induce HDGC. In 2015, a multinational and multidisciplinary task force updated the guidelines and criteria for screening, diagnosing, and managing HDGC. CASE PRESENTATION Here, we present a case series of three siblings with family history of HDGC who tested positive for the CDH1 mutation and describe their surgical treatment course, post-operative management, and follow-up as they pertain to the updated guidelines. CONCLUSIONS Despite recent updates in guidelines in the diagnosis and management of HDGC, the disease remains challenging to address with patients given the high level of uncertainty and the comorbidities associated with prophylactic intervention. We strongly recommend that an interdisciplinary team inclusive of clinical and surgical oncologists, along with geneticists, social work, and psychological support, should follow the patients in a longitudinal and comprehensive manner in order to achieve full recovery and return to normalcy, as with our patients.

Abstract
BACKGROUND AND AIMS The time course for the development of clinically significant hereditary diffuse gastric cancer (HDGC) is unpredictable. Little is known about the progression from preclinical, indolent lesions to widely invasive, aggressive phenotypes. Gastroendoscopy often fails to detect early lesions, and risk-reducing/prophylactic total gastrectomy (PTG) is the only curative approach. We present an HDGC family with early-onset disease in which clinical and histologic findings provided insight into the understanding of different HDGC phenotypes. METHODS The proband was diagnosed at age 18 years with widely invasive, metastatic DGC. CDH1 genetic testing identified a pathogenic, germline CDH1 variant (c.1901C>T, p.Ala634Val). Thirty family members were tested, and 15 CDH1 carriers were identified. RESULTS Six family members had PTG, with negative preoperative workup. The proband's 14-year-old sister is the youngest patient, reported to date, to have PTG after negative preoperative biopsy sampling. Intramucosal HDGC foci were detected in all PTG specimens (1-33). In contrast to the "indolent" phenotype of these foci, the aggressive DGC from the proband showed pleomorphic cells, absent E-cadherin expression, increased proliferation (Ki-67 index), and activation of oncogenic events (p53, pSrc and pStat3 overexpression). All family members had Helicobacter pylori gastritis. Cag-A-positive strains were detected in all specimens, except in the proband's sister. CONCLUSIONS HDGC is a heterogeneous disease regarding clinical behavior, endoscopic findings, histopathologic features, and immunophenotypic/molecular profile. The presence of bizarre, pleomorphic cells in endoscopic biopsy specimens is suggestive of advanced disease and should prompt clinical intervention. The involvement of a full multidisciplinary team is essential for the management of these patients.

Abstract
PURPOSE Cervical lymph node (LN) metastases in papillary thyroid cancer (PTC) are common in tumors especially that are larger than 1cm. Ipsilateral central neck dissection (CND) is usually preferred even in the absence of a palpable LN. This study aims to clarify the incidence and predictive factors for occult ipsilateral central LN metastasis in these patients, and the management of patients without clinical evidence of metastasis. METHODS 204 PTC patients were studied. The patients were divided into two according to the tumor size of ≤5mm or larger. Patient demographics, tumor properties, LN metastasis, preoperative neck ultrasonography findings and surgical outcomes were analyzed. RESULTS There were 152 patients in study group-1 (nodule > 5 mm) and 52 patients in group-2 (nodule ≤ 5 mm). The mean tumor size was 11.9 mm. Overall, preoperative neck ultrasonography showed central neck LN in 25 (12.3%) patients, however, final pathology revealed metastatic LN at central compartment in 59 (28.9%) patients. There were 56 (27.5%) patients with metastasis in group-1 compared to 3 (1.4%) patients in group-2. CONCLUSIONS Prophylactic CND is advised in PTC for the reduction of recurrence in central compartment. According to our results, in patients with tumors smaller than 5 mm and without evidence of nodal metastasis in preoperative neck ultrasonography, we do not recommend prophylactic CND.

Abstract
INTRODUCTION Women at high inherited risk of ovarian cancer are advised to undergo risk-reducing bilateral salpingo-oophorectomy (RRBSO) at age 40-45 years or when their families are complete. Most women are premenopausal at this age, so RRBSO will induce surgical menopause. Despite the clear benefits of RRBSO for cancer risk reduction, much less is known about the impact on non-cancer outcomes that contribute to health and well-being and inform surveillance and management strategies. METHODS AND ANALYSIS This will be a multicentre, prospective cohort study of 105 premenopausal high-risk women undergoing RRBSO and an age-matched comparison group of 105 premenopausal women not planning oophorectomy or pregnancy in the next 2 years. The aim of this study is to measure the impact of RRBSO on sexual function (primary outcome) at 24 months in high-risk premenopausal women compared with the comparison group. Secondary outcomes include menopausal symptoms and menopause-related quality of life, mood, sleep quality, markers of cardiovascular disease and pre-diabetes, bone density and markers of bone turnover, and the impact of hormone replacement therapy use on these outcomes. Data analysis methods will include logistic and linear regression using general estimating equations accounting for the repeated outcome measurements within each participant. ETHICS AND DISSEMINATION The study has been approved by institutional ethics committees at each participating centre. Findings will be disseminated through peer-reviewed publications and conference presentations, and national and international networks of centres managing high-risk women, and will inform national and international clinical guidelines. TRIAL REGISTRATION NUMBER The pre-results protocol for this trial is registered with the Australian New Zealand Clinical Trials Registry (anzctr.org.au; registration no: ACTRN12615000082505).

Abstract
To evaluate perceived pain during repetitive annual endometrial sampling at gynaecologic surveillance in asymptomatic women with Lynch syndrome (LS) over time and in addition to symptomatic women without LS, undergoing single endometrial sampling. In this prospective study, 52 women with LS or first degree relatives who underwent repetitive annual gynaecological surveillance including endometrial sampling of which 33 were evaluated twice or more and 50 symptomatic women without LS who had single endometrial sampling, were included. Pain intensity was registered with VAS scores. Differences in pain intensities between subsequent visits (in LS) and between the two groups were evaluated. The use of painkillers before endometrial sampling was registered. If women with LS decided for preventive surgery, the reason was recorded. The LS group reported a median VAS score of 5.0 (range 0-10) at the first surveillance (n = 52) and at the second visit (n = 24). Women who repeatedly underwent endometrial sampling more often used painkillers for this procedure. During the study period 7/52 (13 %) women with LS choose for preventive surgery, another 4/52 (8 %) refused further endometrial sampling. Painful endometrial sampling was mentioned as main reason to quit screening. The median VAS score of the 50 symptomatic women was 5.0 (range 1-9). Endometrial sampling, irrespective of indication, is a painful procedure, with a median VAS score of 5.0. During subsequent procedures in women with LS, the median pain score does not aggravate although one in five women chose an alternative for endometrial sampling.

Bilateral Oophorectomy and Breast Cancer Risk in BRCA1 and BRCA2 Mutation Carriers. J Natl Cancer Inst 2017; 109:2905636. [PMID: 27601060 PMCID: PMC6284253 DOI: 10.1093/jnci/djw177] [Citation(s) in RCA: 111] [Impact Index Per Article: 15.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Revised: 03/23/2016] [Accepted: 06/17/2016] [Indexed: 12/28/2022] Open
Abstract
Background Whether oophorectomy reduces breast cancer risk among BRCA mutation carriers is a matter of debate. We undertook a prospective analysis of bilateral oophorectomy and breast cancer risk in BRCA mutation carriers. Methods Subjects had no history of cancer, had both breasts intact, and had information on oophorectomy status (n = 3722). Women were followed until breast cancer diagnosis, prophylactic bilateral mastectomy, or death. A Cox regression model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of breast cancer associated with oophorectomy (coded as a time-dependent variable). All statistical tests were two-sided. Results Over a mean follow-up of 5.6 years, 350 new breast cancers were diagnosed. Among women with a BRCA1 or BRCA2 mutation, oophorectomy was not associated with breast cancer risk compared with women who did not undergo an oophorectomy. The age-adjusted hazard ratio associated with oophorectomy was 0.96 (95% CI = 0.73 to 1.26, P = 76) for BRCA1 and was 0.65 (95% CI = 0.37 to 1.16, P = 14) for BRCA2 mutation carriers. In stratified analyses, the effect of oophorectomy was statistically significant for breast cancer in BRCA2 mutation carriers diagnosed prior to age 50 years (age-adjusted HR = 0.18, 95% CI = 0.05 to 0.63, P = 007). Oophorectomy was not associated with risk of breast cancer prior to age 50 years among BRCA1 mutation carriers (age-adjusted HR = 0.79, 95% CI = 0.55 to 1.13, P = 51). Conclusions Findings from this large prospective study support a role of oophorectomy for the prevention of premenopausal breast cancer in BRCA2, but not BRCA1 mutation carriers. These findings warrant further evaluation.

Abstract
Breast cancer is the leading cause of cancer-related deaths in women age 40 and younger in developed countries, and although generally improving, survival rates for young women with breast cancer remain lower than for older women. Young women are more likely to develop more aggressive subtypes of breast cancer (more triple negative and more Human Epidermal Growth Factor Receptor 2 [HER2]-positive disease) and present with more advanced stage disease. Previous research has demonstrated that young age is an independent risk factor for disease recurrence and death, although recent data suggest this may not be the case in certain tumor molecular subtypes. Recent preliminary evidence suggests potential unique biologic features of breast cancer that occurs in young women although this has yet to have been translated into treatment differences. There are clearly host differences that affect the management of breast cancer for young patients including generally being premenopausal at diagnosis, and fertility, genetics, and social/emotional issues in particular should be considered early in the course of their care. Despite an increased risk of local recurrence, young age alone is not a contraindication to breast conserving therapy given the equivalent survival seen in this population with either mastectomy or breast conservation. However, many young women in recent years are choosing bilateral mastectomy, even without a known hereditary predisposition to the disease. For those who need chemotherapy, multi-agent chemotherapy and biologic therapy targeting the tumor similar to the treatment in older women is the standard approach. Select young women will do well with hormone therapy only. Recent data from the TEXT and SOFT trials evaluating the optimal endocrine therapy for the first 5 years, and the ATTom and ATLAS trials demonstrating benefit from extended duration of tamoxifen (10 vs. 5 years), have further defined options for adjuvant endocrine therapy for young women with early breast cancer. Attention to adherence with endocrine therapy may be particularly important to improve outcomes in this population who are at increased risk of non-adherence compared to older women.

Abstract
BACKGROUND Breast cancer is the most common cancer in women worldwide, and is a leading cause of cancer death among women. Prophylactic or curative mastectomy is often followed by breast reconstruction for which there are several surgical approaches that use breast implants with which surgeons can restore the natural feel, size and shape of the breast. OBJECTIVES To assess the effects of different types of breast implants on capsular contracture, surgical short- and long-term complications, postoperative satisfaction level and quality of life in women who have undergone reconstructive breast surgery after mastectomy. SEARCH METHODS We searched the Cochrane Breast Cancer Group's Specialised Register on 20 July 2015, MEDLINE (1985 to 20 July 2015), EMBASE (1985 to 20 July 2015) and the Cochrane Central Register of Controlled Trials (CENTRAL; Issue 8, 2015). We also searched the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov on 16 July 2015. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared different types of breast implants for reconstructive surgery. We considered the following types of intervention: implant envelope surfaces - texturised versus smooth; implant filler material - silicone versus saline, PVP-Hydrogel versus saline; implant shape - anatomical versus round; implant volume - variable versus fixed; brands - different implant manufacturing companies and implant generation (fifth versus previous generations). DATA COLLECTION AND ANALYSIS Two review authors independently assessed methodological quality and extracted data. We used standard Cochrane methodological procedures. The quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. MAIN RESULTS Five RCTs with 202 participants met the inclusion criteria. The women participants were typically in their 50s, and the majority of them (about 82%) received reconstructive surgery following breast cancer, while the others had reconstructive surgery after prophylactic mastectomy. The studies were heterogenous in terms of implant comparisons, which prevented us from pooling the data.The studies were judged as being at an unclear risk of bias for most risk of bias items owing to poor quality of reporting in the trial publications. Three of the five RCTs were judged to be at high risk of attrition bias, and one at high risk of detection bias.Textured silicone versus smooth silicone implants: textured implants were associated with worse outcomes when compared to smooth implants (capsular contracture: risk ratio (RR) 0.82, 95% CI 0.14 to 4.71; 1 study, 20 participants; very low quality evidence; reintervention: RR 0.82, 95% CI 0.14 to 4.71; 1 study, 20 participants; very low quality evidence). No results in this comparison were statistically significant.Silicone versus saline implants: saline-filled implants performed better than silicone-filled implants for some outcomes; specifically, they produced less severe capsular contracture (RR 3.25, 95% CI 1.24 to 8.51; 1 study, 60 participants; very low quality evidence) and increased patient satisfaction (RR 0.60, 95% CI 0.41 to 0.88; 1 study, 58 participants; very low quality evidence). However reintervention was significantly more frequent in the saline-filled implant group than in the silicone-filled group (OR 0.08, 95% CI 0.01 to 0.43; 1 study, 60 participants; very low quality evidence).Poly(N-vinyl-2-pyrrolidone) hydrogel-filled (PVP-hydrogel) versus saline-filled implants: PVP-hydrogel-filled implants were associated with worse outcomes when compared to saline-filled implants (capsular contracture: RR 3.50, 95% CI 0.83 to 14.83; 1 study, 40 participants; very low quality evidence; short-term complications: RR 2.10, 95% CI 0.21 to 21.39; 1 study, 41 participants; very low quality evidence).Anatomical versus round implants: anatomical implants were associated with worse outcomes than round implants (capsular contracture: RR 2.00, 95% CI 0.20 to 20.15; 1 study, 36 participants; very low quality evidence; short-term complications: RR 2.00, 95% CI 0.42 to 9.58; 1 study, 36 participants; very low quality evidence; reintervention: RR 1.50, 95% CI 0.51 to 4.43; 1 study, 36 participants; very low quality evidence). No results in this comparison were statistically significant.Variable-volume versus fixed-volume implants: data about one-stage reconstruction using variable-volume implants were compared with data about fixed-volume implants positioned during the second surgical procedure of two-stage reconstructions. Fixed-volume implant reconstructions were possibly associated with a greater number of women reporting that their reconstruction corresponded with expected results (RR 0.25, 95% CI 0.10 to 0.62; 1 study, 40 participants; very low quality evidence) and fewer reinterventions (RR 7.00, 95% CI 1.82 to 26.89; 1 study, 40 participants; very low quality evidence) when compared to variable-volume implants. A higher patient satisfaction level (rated from 1 to 6, with 1 being very bad and 6 being very good) was found with the fixed-volume implants for overall aesthetic result (mean difference (MD) -1.10, 95% CI -1.59 to -0.61; 1 study, 40 participants; very low quality evidence).There were no studies that examined the effects of recent (fifth) generation silicone implants versus previous generations or different implant manufacturing companies. AUTHORS' CONCLUSIONS Despite the central role of breast reconstruction in women with breast cancer, the best implants to use in reconstructive surgery have been studied rarely in the context of RCTs. Furthermore the quality of these studies and the overall evidence they provide is largely unsatisfactory. Some of our results can be interpreted as early evidence of potentially large differences between different surgical approaches, which should be confirmed in new high-quality RCTs that include a larger number of women. These days - even after a few million women have had breasts reconstructed - surgeons cannot inform women about the risks and complications of different implant-based breast reconstructive options on the basis of results derived from RCTs.

Abstract
Breast cancer (BC) is the leading cancer among women worldwide and in 5-10 % of cases is of hereditary origin, mainly due to BRCA1/2 mutations. Therefore, the German Consortium for Familial Breast and Ovarian Cancer (HBOC) with its 15 specialized academic centers offers families at high risk for familial/hereditary cancer a multimodal breast cancer surveillance program (MBCS) with regular breast MRI, mammography, ultrasound, and palpation. So far, we know a lot about the psychological effects of genetic testing, but we know little about risk-correlated adherence to MBCS or prophylactic surgery over time. The aim of this study was to investigate counselees' adherence to recommendations for MBCS in order to adjust the care supply and define predictors for incompliance. All counselees, who attended HBOC consultation at the University Hospital Heidelberg between July 01, 2009 and July 01, 2011 were eligible to participate. A tripartite questionnaire containing sociodemographic information, psychological parameters, behavioral questions, and medical data collection from the German consortium were used. A high participation rate was achieved among the study population, with 72 % returning the questionnaire. This study showed a rate of 59 % of full-adherers to the MBCS. Significant predictors for partial or full adherence were having children (p = 0.0221), younger daughters (p = 0.01795), a higher awareness of the topic HBOC (p = 0.01795, p < 0.0001), a higher perceived breast cancer risk (p < 0.0001), and worries (p = 0.0008)/impairment (p = 0.0257) by it. Although the current data suggest a good adherence of MBCS, prospective studies are needed to understand counselees' needs to further improve surveillance programs and adherence to them. Adherence to the breast cancer surveillance program for women at risk for familial breast and ovarian cancer versus overscreening-a monocenter study in Germany.

[PMID: 26946931 DOI: 10.1016/j.anplas.2016.02.002] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2015] [Accepted: 02/03/2016] [Indexed: 12/20/2022]
Abstract
BACKGROUND Prophylactic surgery remains the most effective modality for reducing both breast and ovarian cancer rate in woman at high risk, such as BRCA1 or BRCA2. Autologous breast reconstruction with bilateral deep inferior epigastric perforator (DIEP) flap allows predictable and durable results. However, existing two-step approach separating salpingo-oophorectomy and reconstruction could even make DIEP flap impossible, or make insufflation more difficult during laparoscopy. Other authors described one-step procedure but with open laparotomy. The goal of this study was to verify the feasibility of a simultaneous procedure, including laparoscopic salpingo-oophorectomy. METHODS We included BRCA mutation careers scheduled for simultaneous laparoscopic salpingo-oophorectomy, and bilateral breast reconstruction with DIEP flaps. The first step of the procedure was laparoscopic salpingo-oophorectomy and ports had to be strategically placed to avoid interference with the following procedure. The second step was bilateral breast reconstruction with DIEP flaps. We reviewed medical charts. Surgical procedure was analyzed for duration, revisions and surgical complications. RESULTS During 1-year period, eight patients agreed to a simultaneous procedure. All of them were BRCA positive, mean age was 38.3years (range, 39-50), and mean BMI was 28.3kg/m(2) (range, 21-33). The mean duration of the entire procedure was 524minutes (range, 405-630) and the mean hospital stay 9.2 days (range, 8-14). There was 100% flap survival. No abdominal wall dehiscence occurred. CONCLUSION One-step procedure for prophylactic surgery of ovarian and breast hereditary malignancies is feasible. First salpingo-oophorectomy with open laparoscopy then bilateral immediate or delayed breast reconstruction with DIEP flaps can be performed.

Abstract
In France, women carrying BRCA1/2 mutation, at an identified high risk of breast cancer are recommended to undergo breast MRI screening. That screening does not however prevent the risk of developing a breast cancer. The only alternative to breast cancer screening available in France is surgical prevention by prophylactic mastectomy. An interesting option for women who wish to reduce their breast cancer risk, but are unready for prophylactic mastectomy is a preventive hormonal treatment by aromatase inhibitors, or selective estrogens receptor modulators (SERMs). Reliable clinical trials show the efficiency of tamoxifen, raloxifen, exemestane, and anastrozole especially, in reducing breast cancer incidence by 33%, 34%, 65% and 53% respectively. This article tries to sum up the main published trials of breast cancer prevention with hormonal treatment, and presents the latest American and English clinical guidelines concerning hormonal prevention for women at high risk of breast cancer, and starts thinking about the possibilities of hormonoprevention, especially among women carrying a BRCA1/2 mutation in France.

Abstract
Angelina Jolie's announcement that she is a BRCA1 carrier and has had a prophylactic bilateral mastectomy was met with widespread support as well as speculation about its possible impact on the public. These speculations were the subject of a Time magazine cover story titled "The Angelina Effect" (Kluger et al., 2013 ). Although there is anecdotal evidence to support this hypothesized Angelina effect, empirical tests are lacking. To explore possible links between Angelina's announcement and public health, we surveyed 356 adults immediately after the announcement. Guided by a model of celebrity influence, the survey assessed participants' demographics and health history, identification and parasocial interaction with Jolie, and genetic testing intentions. Results supported the model's predictions and provided preliminary evidence of an Angelina effect.

Abstract
The last 5 years have brought significant innovation and advancement in the genetics of breast cancer. This clinical opinion aims to summarize and update current approaches to the care of women at risk for a hereditary predisposition to breast cancer. Implications of the BRCA mutation and several other hereditary syndromes will be discussed. Risk assessment and criteria for referral to cancer genetic professionals as well as high-risk screening and prophylactic options will be reviewed. Finally, the newly available genetic cancer panels and implications of mutations in some of these lesser known genes will be discussed. As the field of cancer genetics continues to evolve, the education of medical students, residents, and faculty will be paramount to identify appropriate candidates for genetic counseling and testing in conjunction with cancer genetic professionals.

Abstract
BACKGROUND The benefits of prophylactic central compartment lymph node dissection (pCCND) in papillary thyroid cancer (PTC) are still under investigation. This treatment seems to reduce PTC recurrence/mortality rates but has a higher risk of surgical complications. The lack of prospective randomized trials does not allow definitive recommendations. The aim of this prospective randomized controlled study was to evaluate the clinical advantages and disadvantages of pCCND. PATIENTS A total of 181 patients with PTC without evidence of preoperative/intraoperative lymph node metastases (cN0) were randomly assigned to either Group A (n = 88) and treated with total thyroidectomy (TTx) or Group B (n = 93) and treated with TTx + pCCND. RESULTS After 5 years of followup, no difference was observed in the outcome of the two groups. However, a higher percentage of Group A were treated with a higher number of (131)I courses (P = .002), whereas a higher prevalence of permanent hypoparathyroidism was observed in Group B (P = .02). No preoperative predictors of central compartment lymph node metastases (N1a) were identified. Only three patients were upstaged, and the therapeutic strategy changed in only one case. CONCLUSIONS cN0 patients with PTC treated either with TTx or TTx + pCCND showed a similar outcome. One advantage of TTx + pCCND was a reduced necessity to repeat (131)I treatments, but the disadvantage was a higher prevalence of permanent hypoparathyroidism. Almost 50% of patients with PTC had micrometastatic lymph nodes in the central compartment, but none of the presurgical features analyzed, including BRAF mutation, was able to predict their presence; moreover, to be aware of their presence does not seem to have any effect on the outcome.

Abstract
BACKGROUND In recent years, radical breast cancer surgery has been largely replaced by breast conservation treatment, due to early diagnosis and more effective adjuvant treatment. While breast conservation is mostly preferred, the trend of bilateral mastectomy has risen in the United States. The aim of this study is to determine factors influencing patients' choice for having contralateral prophylactic mastectomy (CPM). METHODS This is a retrospective study of 373 patients diagnosed with primary invasive breast cancer who were treated by bilateral or unilateral mastectomy (BM or UM) at the Revlon/UCLA Breast Center between Jan. 2002 and Dec. 2010. In the BM group, only those with unilateral breast cancer who chose CPM were included in the analysis. RESULTS When compared with the UM group, the following factors were found to be associated with BM: younger age, pre-menopausal, a family history of breast/ovarian cancer, BRCA mutation, more breast biopsies, history of breast augmentation, having MRI study within 6 months before the surgery, more likely to have reconstruction and sentinel lymph node biopsy (SLNB) and fewer had neoadjuvant/adjuvant chemotherapy/radiation. When patients with bilateral breast cancer were excluded, multivariate logistic regression analysis indicated younger patients with negative nodes, SLNB as the only nodal surgery and positive family history were significant factors predicting CPM and immediate reconstruction using tissue expanders or implants. CONCLUSION Younger age, lower TN stage, requiring only SLNB and high risk family history predict contralateral prophylactic mastectomy. Tissue expander/implant-based reconstructions were more frequently chosen by patients with BM.

Abstract
INTRODUCTION The incidence of impacted wisdom teeth (third molars) is high, with some 72% of Swedish people aged 20 to 30 years having at least one impacted wisdom tooth. Impacted wisdom teeth occur because of a lack of space, obstruction, or abnormal position. They can cause inflammatory dental disease manifested by pain and swelling of infected teeth and may destroy adjacent teeth and bone. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical questions: Should asymptomatic, disease-free impacted wisdom teeth be removed prophylactically? What are the effects of different operative (surgical) techniques for removing impacted wisdom teeth? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We performed a GRADE evaluation of the quality of evidence for interventions. RESULTS We found 11 studies that met our inclusion criteria. CONCLUSIONS In this systematic review, we present information relating to the effectiveness and safety of the following interventions: prophylactic extraction, active surveillance, and different operative (surgical) techniques for extracting impacted wisdom teeth.

Abstract
Hereditary diffuse gastric cancer (HDGC) is an autosomal dominate cancer syndrome that leads to an increased risk of developing invasive diffuse type (signet ring cell) gastric carcinoma. Approximately 30% of HDGC cases are caused by a germline mutation involving the E-cadherin (CDH1) gene. Those with the CDH1 mutation have an 80% and 60% cumulative lifetime risk of developing diffuse type gastric carcinoma and lobular breast carcinoma respectively. Due to the focal nature of early diffuse type gastric carcinoma, identifying early lesions with surveillance endoscopy is limited. As a result, elective risk-reducing total gastrectomy is currently recommended. In this report, the clinical, intraoperative, and pathologic work-up is reviewed regarding a patient with known CDH1 germline mutation.

Abstract
PURPOSE Women with BRCA1/2 mutations have higher risk for breast and ovarian cancers. Available intervention actions include prophylactic surgeries and breast screening, which vary significantly in cost, cancer prevention, and in resulting death from other causes. We present a model designed to yield optimal intervention strategies for mutation carriers between the ages of 30 and 65 and any prior intervention history. METHODS A Markov decision process (MDP) model is developed that considers yearly state transitions for the mutation carriers and state dependent intervention actions. State is defined as a vector comprising mutation type, health states, prior intervention actions, and age. A discounted value iteration algorithm is used to obtain optimal strategies from the MDP model using both cost and quality-adjusted life years (QALYs) as rewards. RESULTS The results from MDP model show that for 30-year-old women with BRCA1 mutation and no prior intervention history, the cost-optimal strategy is a combination of prophylactic mastectomy (PM) and prophylactic oophorectomy (PO) at age 30 with no screening afterwards. Whereas, the QALYs-optimal strategy suggests PO at age 30 and PM at age 50 with screening afterwards. For BRCA2 mutation carriers at age 30, the cost-optimal strategy is PO at age 30, PM at age 40, and yearly screening only after age 56. Corresponding QALYs-optimal strategy is PM at age 40 with screening. Strategies for all other ages (31 to 65) are obtained and presented. It is also demonstrated that the cost-optimal strategies offer near maximum survival rate and near minimum cancer incidence rates by age 70, when compared to other ad hoc strategies.
