Active clinical trials for "Breast Neoplasms"

The purpose of this study is to investigate if sentinel lymph node biopsy is a reliable staging tool for breast cancer patients planned for neoadjuvant chemotherapy (=before breast surgery) and if, in that case, it is safe to omit axillary lymph node dissection if the sentinel lymph node is free of metastasis.

This is a pain survey study that will compare the level of discomfort experienced by breast cancer patients after injection of either technetium-labeled sulfur colloid or technetium-labeled tilmanocept, both FDA-approved agents used for sentinel lymph node biopsy (SLNB). Breast cancer patients who are already scheduled for SLNB as part of their original surgical plan will be asked to participate in this study and be randomized to receive either technetium-labeled sulfur colloid or technetium-labeled tilmanocept. After injection, patients will complete pain questionnaires to measure the amount of discomfort they are feeling during and after they receive the injection. There will be no change to the patient's treatment plan other than the addition of pain questionnaires. The investigators' hypothesis is that patients will feel less discomfort after injection of tilmanocept versus sulfur colloid.

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.

This is a non-interventional, retrospective, multicentre study involving women having had a breast cancer during their pregnancy, diagnosed between 2000 and 2014 (cases) and non-pregnant women having had a breast cancer between 2000 and 2009 (controls).

The genetic polymorphisms of the cytochrome P450 may influence on the metabolism of tamoxifen. The investigators want to evaluate the frequency or incidence of the genetic polymorphisms of cytochrome P450 subfamilies(CYP2D6, CYP3A4/5 and CYP2C19) in breast cancer patients, and analyze the association between the genetic polymorphisms of cytochrome P450 subfamilies and clinical outcomes in breast cancer patients treated by adjuvant tamoxifen therapy.

The investigators want to develop a gene expression profile for the prediction of immunotherapy response of patients with metastatic breast cancer presenting malignant pleural effusion.

A prospective, multicenter study: Primary objective: to assess the diagnostic yield of screening MRI compared to physical examination, mammography or ultrasonography in the detection of recurrence in patients treated with breast conserving therapy Secondary objective: to describe the size, type, grade, and nodal status of cancers seen only on MRI and to estimate the rate of benign biopsies and short interval follow-up induced only by MRI in this population.

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.
