Active clinical trials for "Breast Neoplasms"

Diagnostic performance of digital breast tomosynthesis (DBT) would be not inferior to the that of breast ultrasound in women with dense breast.

The purpose of this study is to determine discordant HER2/neu status of primary breast tumor and metastatic breast cancer cells at regional lymph nodes in node positive breast cancer patients.

The aim of the study is to investigate the impact of adjuvant chemotherapy on cognitive function in patients aged over 65 and suffering from breast cancer or colon.

Breast implants are currently used for cosmetic breast augmentation and in breast reconstruction following mastectomy for breast cancer. Fat grafting is a technique where fat is injected around the periphery of a breast implant to camouflage the transition between implant and the body. The investigators propose to show mammography images of women who have had breast implants with fat grafting to informed and blinded radiologists and evaluate their readings of the images. Hypothesis: with mammographic screening, radiologists will be able to distinguish between findings associated with fat grafting and those which are suspicious for breast cancer.

The research team is studying why some African American families have multiple cases of breast cancer. This study will help to better understand if there are undiscovered genes unique to African Americans that may predict early breast cancer risk. Breast cancer survivors AND their relatives who are also breast cancer survivors are being recruited to the study.

The purpose of this study is to better understand why some women with breast cancer develop chronic pain.

A multicenter randomized controlled trial to evaluate the performance of MRI, in terms of sensitivity, specificity, and predictive value, in the screening of women at intermediate risk of breast cancer. Two surveillance programs will be compared. Women will be randomly assigned with a 1:1 ratio to: Yearly two-view mammography (Mx) and breast ultrasonography (US) or Yearly MRI.

This randomized clinical trial studies how well minocycline hydrochloride works in reducing chemotherapy induced depression and anxiety in patients with stage I-III breast cancer. Minocycline hydrochloride may prevent changes in memory and thinking and improve the quality of life of breast cancer patients receiving chemotherapy.

Longitudinal Evaluation of Taxane induced neuropathy in early stage breast cancer.

Rationale: In breast cancer (BC) patients, lymph node status is a key prognostic indicator. At present, axillary ultrasound (US) with subsequent fine needle aspiration cytology (FNAC) of suspicious lymph nodes (US+FNAC) is widely used as a pre-operative staging method. When US+FNAC is negative, a sentinel node procedure (SNP) is performed during breast surgery. Nowadays, an axillary lymph node dissection (ALND) is generally performed if one of the abovementioned diagnostic entities reveals lymph node metastases. However, the extensive role of ALND in BC patients with lymph node metastases may change or diminish in upcoming years due to emerging evidence that completion ALND (cALND) does not affect disease-free survival and overall survival in early BC patients with (sentinel) node-positive disease. Whether ALND is needed in these patients, should be based on (axillary) tumour load. Because of the fact that tumour load can only be reliably evaluated by SNP and not by US+FNAC, the role of SNP might become even more important in upcoming years. Ideally, the status of this sentinel lymph node is known prior to breast surgery, so a patient tailored treatment plan can be made and discussed with the patient before breast surgery. In this context, it would be very logical to perform a SNP under local anaesthesia (LA), prior to breast surgery. This might not only lead to significantly less two-step surgical procedures under general anaesthesia (GA), but might also lead to a reduction of depressive symptoms and anxiety and improved quality of life (QoL) of BC patients, because BC patients are in particular risk for psychological distress in the first three months after diagnosis of BC. Knowing lymph node status and the complete treatment plan as soon as possible (by performing a SNP under LA), might reduce this psychological distress. To investigate which BC patients would benefit most from SNP under LA, the investigators recently analysed 1132 BC patients retrospectively. Both prevalence of axillary lymph node metastases and prevalence of false negative results of US+FNAC were directly associated with age <60 years and with primary breast tumour size >20 mm. Hence, these BC patients might benefit most from SNP under LA. In the present study, the value of SNP under LA in these BC patients (i.e. <60 years with a breast carcinoma >20 mm) will be analysed. Objectives: Reduction of the mean number of operations under general anaesthesia per patient. Improvement of QoL. Reduction of depressive symptoms and experienced anxiety. Study design: Prospective single centre randomised controlled clinical trial. Study population: Women aged 18 to 60 years who are diagnosed with BC AND with a tumour size of >20 mm ultrasonographically AND with a negative or inconclusive pre-operative US+FNAC. Intervention: Sentinel Node Procedure under Local Anaesthesia (SNP under LA) Control: Traditional Sentinel Node Procedure under General Anaesthesia (SNP under GA) Main study parameters: Primary outcome parameters are the number of operations under GA per patient and the number of operations under LA per patient. Secondary outcome parameters are QoL, experienced depressive symptoms and anxiety. Timeline and statistics: The inclusion period will be conducted from the 1st of July 2014 to the 1st of August 2015, and 80 patients will be enrolled in this study (alpha 0.05; power 0.8). Inclusion of 80 patients will be sufficient to reduce the number of two-stage surgical procedures under general anaesthesia with 30%. Data will be analysed using descriptive statistics, Chi-squared test, Fisher's exact test, Mann-Whitney U test, Kruskall-Wallis test, students t-test, ANOVA, paired t-test, Wilcoxon signed-rank test, Friedman test, Pearson's and Spearman's rank correlation coefficients and finally logistic and linear regression analysis.
