BACKGROUND: There has been some doubts raised in earlier studies about the efficacy of hormone replacement therapy (HRT) in reducing endocrine and sexual problems in women who have undergone a risk-reducing salpingo-oophorectomy (RRSO). METHODS: In this prospective, observational study, we recruited 178 premenopausal women with a high risk for ovarian cancer. Fifty-seven women opted for RRSO and 121 for gynaecological screening (GS). Women completed questionnaires before surgery (T1) and 3 (T2) and 9 (T3) months post surgery, or at equivalent time points for the GS-group...

BACKGROUND: In anticipation of bundled-payment models for thyroid and parathyroid disease, a better understanding of resource utilization following surgery is required. We sought to characterize the use of hospital services following such operations using an analysis of readmissions. METHODS: Patients age 18+years who underwent a thyroid or parathyroid operation in CA or NY (2008-2011) were classified by procedure type. Primary outcome was readmission within 90 days...

BACKGROUND: The prognostic value of WHO grade in pancreatic neuroendocrine tumors (PanNETs) in patients with Multiple Endocrine Neoplasia Type 1 (MEN1) is unknown. METHODS: We performed a cohort study using the Dutch National MEN1 database, which includes >90% of the Dutch MEN1 population with data collected between 1990 and 2014. Formalin-fixed paraffin embedded tissue blocks from the largest resected PanNET per patient were collected. MIB1 staining was performed and KI67 labeling index (LI) was determined by manual eye-counting under a microscope and by digital image analysis...

BACKGROUND: Acromegaly is caused by elevated secretion of human growth hormone, which is frequently because of intracranial tumors. This diagnosis is fairly uncommon with an incidence of 3 to 4 cases per million patients per year. We are presenting a case of acromegaly diagnosed in an active duty Chief Petty Officer. MATERIALS AND METHODS: A 38-year-old male Chief Petty Officer with no previous mental health diagnosis experienced post-traumatic stress disorder (PTSD)-like symptoms in early 2012 after deploying to Iraq and Afghanistan from 2010 to 2011...

BACKGROUND: Recent studies suggest that the encapsulated form of follicular variant of papillary thyroid cancer (eFVPTC) behaves more similarly to benign lesions and can be treated with thyroid lobectomy alone instead of total thyroidectomy. To distinguish aggressive cancers from more benign lesions more clearly, the objective of this study was to determine if the eFVPTC behaves less aggressively than the nonencapsulated variant (neFVPTC). METHODS: A prospectively collected endocrine surgery database in our institution was reviewed for all patients with FVPTC on surgical pathology from 1999 to 2012...

OBJECTIVES: Buprenorphine is a common analgesic in experimental research, due to effectiveness and having few side-effects, including a limited influence in the immune and endocrine systems. However, how buprenorphine affects cytokine levels and the adrenal and thyroid response during general anesthesia and surgery is incompletely understood. This study aimed to assess whether buprenorphine modulated significantly those responses in rats submitted to general anesthesia, mechanical ventilation, and surgical insertion of intravascular catheters...

Inhibition of proliferation in estrogen receptor-positive (ER(+)) breast cancers after short-term antiestrogen therapy correlates with long-term patient outcome. We profiled 155 ER(+)/human epidermal growth factor receptor 2-negative (HER2(-)) early breast cancers from 143 patients treated with the aromatase inhibitor letrozole for 10 to 21 days before surgery. Twenty-one percent of tumors remained highly proliferative, suggesting that these tumors harbor alterations associated with intrinsic endocrine therapy resistance...

INTRODUCTION: Mixed adenoneuroendocrine carcinomas (MANECs) derived from cystic duct are extremely rare. PRESENTATION OF CASE: An 80-year-old woman was admitted to the department of surgery, Onomichi general hospital with abnormal liver function and jaundice. Enhanced abdominal computed tomography (CT) detected a well-enhanced papillary tumor in the cystic duct, which protruded into the common bile duct. The intrahepatic bile duct was dilated due to tumor obstruction...

PURPOSE: Peripheral neuropathy (PN) is a common and distressing complication from chemotherapy. Symptoms often, but not always, improve with time. The prevalence of long-term PN symptoms in breast cancer survivors is not well known. We sought to explore PN symptoms and associated risk factors among breast cancer survivors at least 2 years out from diagnosis. METHODS: We performed a cross-sectional retrospective study investigating the prevalence of patient-reported numbness, tingling, and anesthesia symptoms as a surrogate for PN in breast cancer survivors...

BACKGROUND: Insulinomas are the most common pancreatic neuroendocrine neoplasms. In spite of adequate pre-operative localisation, conventional surgical methods rely on intraoperative palpation. Intraoperative ultrasonography (IOUS) is said to aid in accurate localisation, decreases morbidity. Laparoscopic removal of pancreatic endocrine neoplasms is beneficial due to magnification and minimal invasion; however, in the absence of IOUS, error of judgement may lead to conversion to open surgery, thereby relying on 'palpation method' to localise the tumour...

PURPOSE: Breast-conserving surgery (BCS) followed by radiotherapy (RT) with or without endocrine therapy (ET) is a standard treatment option for ductal carcinoma in situ (DCIS). We sought to investigate national patterns in the use of adjuvant therapy after BCS for hormone receptor (HR)-positive DCIS over time. PATIENTS AND METHODS: Using data from the National Cancer Data Base, we identified patients diagnosed with DCIS and treated with BCS between 2004 and 2013...

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome often associated with fibroblast growth factor 23 (FGF23)-producing tumors such as phosphaturic mesenchymal tumor, mixed connective tissue variant (PMTMCT) affecting the bone and soft tissue. We experienced a patient with progressive bone and muscle pain due to FGF23-related TIO. Venous sampling had strongly suggested the anterior skull base as a source of FGF23, which led to the discovery of a small tumor in the ethmoid sinus extending intracranially...

BACKGROUND: Women with ductal carcinoma in situ (DCIS) are increasingly choosing bilateral mastectomy. We sought to quantify rates of contralateral breast cancer (CBC) and ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) for DCIS, and to compare risk factors for CBC and IBTR. METHODS: From 1978 to 2011, DCIS patients undergoing BCS with a contralateral breast at risk were identified from a prospectively maintained database. The association of clinicopathologic and treatment factors with CBC and IBTR were evaluated using Kaplan-Meier analysis, multivariable Cox regression, and competing risk regression (CRR)...

INTRODUCTION: While breast cancer outcomes are improving steadily in younger women due to advances in screening and improved therapies, there has been little change in outcomes among the older age group. It is inevitable that comorbidities/frailty rates are higher, which may increase the risks of some breast cancer treatments such as surgery and chemotherapy, many older women are healthy and may benefit from their use. Adjusting treatment regimens appropriately for age/comorbidity/frailty is variable and largely non-evidence based, specifically with regard to rates of surgery for operable oestrogen receptor-positive disease and rates of chemotherapy for high-risk disease...

In the last decades, in minimally invasive adrenal surgery, the retroperitoneoscopic adrenalectomy (PRA) has shown favorable results when compared to the laparoscopic transperitoneal adrenalectomy (LTA). However, for many endocrine surgeons it is unclear if, when, and how to transition from LTA to PRA. Although the length of the learning curve for both approaches is comparable, the LTA is a technically more challenging procedure whilst PRA demands an orientation in a new environment in a patient that is positioned upside down...

FGFR1 amplification occurs in ~15% of ER+ human breast cancers. We investigated mechanisms by which FGFR1 amplification confers antiestrogen resistance to ER+ breast cancer.<br /><br />Experimental Design: ER+ tumors from patients treated with letrozole before surgery were subjected to Ki67 immunohistochemistry, FGFR1 FISH, and RNA-sequencing. ER+/FGFR1 amplified breast cancer cells and patient-derived xenografts (PDXs) were treated with FGFR1 siRNA or the FGFR tyrosine kinase inhibitor lucitanib...

BACKGROUND: In cases of meningioma surrounding the optical apparatus, this study sought to reduce the incidence of radiation-induced optical neuropathy resulting from gamma knife surgery (GKS) by dividing the treatment volume into 2 or 3 fractions. METHODS: Four patients with a large skull base meningioma (1 male and 3 females; median age: 42 years; range: 33-43 yrs) were treated using volume-staged GKS. In stage I, the large basal part of the tumor (13.2 mL; range: 3...

BACKGROUND: Endocrine surgery continues to mature as a subspecialty field. We describe the clinical performance of an academic endocrine surgery program (ESP) over its first 10 years. METHODS: We examined all endocrine procedures performed during the 10-year period (2006-2015) following the inception of the ESP. Institutional and state-level data on case volume, patient geographic origin, and hospital-side costs were obtained. RESULTS: Endocrine case volume increased by approximately ninefold over the study period (from 102 cases in 2006 to 919 cases in 2015)...

REVIEW
R Thomas, A Pieri, H Cain
INTRODUCTION: The use of primary endocrine therapy (PET) in managing breast cancer in the elderly has become common practice. Whilst there appears to be no difference in overall survival in comparison with surgery, PET has been found to be inferior in local disease control with a limited duration of efficacy (2-3 years). The International Society of Geriatric Oncology (SIOG) state that PET may be considered in patients with a short life expectancy (<2 years) or considered unfit for surgery...
