Evaluation of hereditary/familial breast cancer patients with multigene targeted next generation sequencing panel and MLPA analysis in Turkey.

Breast cancer, a worldwide leading cause of cancer in women, may occur in familial cases. Germline mutations in BRCA1/2 genes are responsible for 15% of the familial cases. With the power of next generation sequencing (NGS) analysis, it is possible to analyze genes related to hereditary susceptibility to breast cancer and investigate the genetic etiology more thoroughly.

Prognostic Importance of Tumor Deposits in the Ipsilateral Axillary Region of Breast Cancer Patients.

Tumor deposits (TD) are irregular discrete tumor masses in adipose tissue, discontinuous from the primary tumor, that are described in various cancers. The incidence and/or prognostic value of TD in breast carcinomas have not been studied so far. We reevaluated 145 breast cancer patients, diagnosed and treated between 2001 and 2006 at our institution for the presence and incidence of TD.

Efficacy and safety of breast radiothermometry in the differential diagnosis of breast lesions.

Aim Of The Study: The aim of this study is to research the contribution of radiothermometry (RTM) to the characterization of breast masses, the differentiation of malignant-benign masses and diagnosis of early stage breast cancer.

Material And Methods: This prospective study comprised 182 cases of patients diagnosed with a breast mass and a control group of 55 cases: a total of 237.

Results: When histopathology is accepted as the gold standard among diagnostic methods, the sensitivity, specificity, and positive-negative predictive value for RTM were 90.

Evaluation of Neoadjuvant Chemotherapy Response with Dynamic Contrast Enhanced Breast Magnetic Resonance Imaging in Locally Advanced Invasive Breast Cancer.

Objective: The reliability of traditional methods such as physical examination, ultrasonography (US) and mammography is limited in determining the type of treatment response in patients with neoadjuvant chemotherapy (NAC) application for locally advanced breast cancer (LABC). Dynamic contrast-enhanced magnetic resonance imaging (MRI) is gaining popularity in the evaluation of NAC response. This study aimed to compare NAC response as determined by dynamic contrast-enhanced breast MRI in patients with LABC to histopathology that is the gold standard; and evaluate the compatibility of MRI, mammography and US with response types.

Invasive micropapillary carcinoma of the breast: a clinicopathologic study of 103 cases of an unusual and highly aggressive variant of breast carcinoma.

Invasive micropapillary carcinoma (IMPC) of the breast is an uncommon, highly aggressive breast cancer that may occur in pure and mixed forms. Our aim in this study is to investigate the relationship between clinical, histopathologic, and immunohistochemical features of pure and mixed IMPC cases diagnosed and treated at our institution. One hundred and three IMPC cases diagnosed at our institution over a period of 19 years have been selected.

Warthin-like papillary carcinoma of the thyroid: a case series and review of the literature.

Warthin-like tumor of the thyroid is a recently described rare variant of thyroid papillary carcinoma. The distinguishing histological feature of this variant is papillary foldings lined by oncocytic neoplastic cells with clear nuclei and nuclear pseudoinclusions, accompanied by prominent lymphocytic infiltrate in the papillary stalks. Its prognosis has been reported to be almost similar to conventional papillary carcinoma.

Validation of three breast cancer nomograms and a new formula for predicting non-sentinel lymph node status.

Background: The aim of the study was to evaluate the available breast nomograms (MSKCC, Stanford, Tenon) to predict non-sentinel lymph node metastasis (NSLNM) and to determine variables for NSLNM in SLN positive breast cancer patients in our population.

Materials And Methods: We retrospectively reviewed 170 patients who underwent completion axillary lymph node dissection between Jul 2008 and Aug 2010 in our hospital. We validated three nomograms (MSKCC, Stanford, Tenon).

Factors predicting non-sentinel lymph node involvement in sentinel node positive breast carcinoma.

Objective: In routine practice, axillary lymph node dissection is performed in early invasive breast cancer patients with positive sentinel node biopsy. However, sentinel node is the only involved axillary node in 40-70% of patients, and determining factors that predict axillary non-sentinel node involvement will therefore prevent unnecessary axillary lymph node dissection and decrease morbidity.

Material And Method: In this study, 119 invasive breast cancer patients with sentinel node metastasis who underwent axillary lymph node dissection between 1998-2009 at our institution were studied.

Papillary carcinoma arising in subhyoid ectopic thyroid gland with no orthotopic thyroid tissue.

Ectopic thyroid gland with no orthotopic thyroid tissue is extremely rare. The authors present a case of a follicular variant of papillary carcinoma developed from an ectopic thyroid gland with no orthotopic thyroid tissue.

Clinical images. Solitary fibrous tumor of the perithyroidal soft tissue mimicking substernal goiter.

Solitary fibrous tumor is an uncommon neoplasm. We present a case of solitary fibrous tumor of the perithyroidal soft tissue mimicking a substernal goiter.

Papillary thyroid carcinoma mimicking anaplastic thyroid carcinoma following fine-needle aspiration biopsy.

Background: Cutaneous metastases from well-differentiated thyroid carcinomas are rare and usually identified in patients with widely disseminated disease. Fine-needle aspiration biopsy (FNAB) has become an acceptable method for the assessment of thyroid nodules. Very rarely needle track dissemination of tumor cells in the thyroid nodule occurs, but, when this occurs, it is evident many years after the FNAB.

Predicting invasive phenotype with CDH1, CDH13, CD44, and TIMP3 gene expression in primary breast cancer.

We aimed to determine changes in the expression of the genes CDH1, CDH13, CD44, and TIMP3 to look for any relationship between them, HER2 and ESR1 expression at the RNA level, and the histopathological properties of tumors. We also analyzed the expression properties of double-negative (estrogen receptor [ER] and human epidermal growth factor receptor [HER2] both negative) breast tumors. Expression status was studied in fresh tissue at the mRNA level with quantitative PCR using hydrolysis probes.

Pathologic nipple discharge in patients with radiologically invisible mass: review of 28 consecutive sub-areolar explorations.

The carcinoma frequency of clinically and radiologically negative pathologic nipple discharges (PNDs) and the optimum management strategy of these cases are still unclear. In this study, the frequency of cancer and the situation of the classic surgical intervention in patients with PND and invisible mammographic and ultrasonographic results are reviewed. The data pertaining to the cases of sub-areolar exploration and major duct excision in a surgery clinic of university hospital from December 2002 to June 2007 have been examined in detail.

Carnitine protects the intestine against reperfusion injury in rats.

Background: Although the negative effects of ischemia on anastomotic healing have been shown in many studies, there is no adequate information on the effects of reperfusion injury. Therefore, in this study, we investigated the effect of ischemia-reperfusion (IR) injury on intestinal anastomosis and the protective efficiency of carnitine in an experimental relatively short intestinal ischemia and long duration reperfusion model.

Methods: Animals were divided into three groups (n=14).

Unilateral juvenile (virginal) hypertrophy of the breast.

Juvenile hypertrophy of the breast (JHB) is an uncommon, benign disorder and typically occurs in peri-pubertal females. The etiology ofJHB is uncertain. It may represent an end-organ hypersensitivity of the breast to normal levels of sex steroids.

Exposure of surgical staff in surgical probe applications in radioguided parathyroidectomy.

The aim of this study is to calculate the exposure of surgical staff during radioguided parathyroidectomy. Two parathyroidectomy operations on patients with parathyroid adenoma were selected. Fifty-centimeter spaced circles were drawn surrounding the operation bed on the floor of the operation room.
