Predicting nodal status using dynamic contrast-enhanced magnetic resonance imaging in patients with locally advanced breast cancer undergoing neoadjuvant chemotherapy with and without sequential trastuzumab.
HYPOTHESIS Dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) is a reliable and accurate method for monitoring primary tumor response in the breast and can be used as a surrogate to predict final axillary nodal status. DESIGN Retrospective study (October 1, 2004, through February 28, 2006) of 46 patients with clinically staged locally advanced breast cancer. SETTING Comprehens...
متن کاملCan dynamic contrast-enhanced MRI (DCE-MRI) predict tumor recurrence and lymph node status in patients with breast cancer?
The lymph node status is regarded as one of the most important prognostic factors for the overall and disease-free survival of patients with breast cancer. While morphological features and contrast enhancement kinetics of breast cancer shown on dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) have been correlated with tumor histological type, grade, and biomarkers [1–4], there wer...
متن کاملAutomatic Prostate Cancer Segmentation Using Kinetic Analysis in Dynamic Contrast-Enhanced MRI
Background: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) provides functional information on the microcirculation in tissues by analyzing the enhancement kinetics which can be used as biomarkers for prostate lesions detection and characterization.Objective: The purpose of this study is to investigate spatiotemporal patterns of tumors by extracting semi-quantitative as well as w...
متن کاملRadiological imaging features of invasive micropapillary carcinoma of the breast and axillary lymph nodes.
Invasive micropapillary carcinoma of the breast is of growing clinical significance. The purpose of this study was to identify the radiological imaging features for this type of breast carcinoma and the axillary lymph nodes. The study population consisted of 30 breast cancer patients (8 invasive micropapillary carcinomas and 22 other types of invasive ductal carcinoma). The breast lesions were ...
متن کاملDiagnostic accuracy of metastatic axillary lymph nodes in breast MRI
PURPOSE The most important prognostic variable for early stage breast cancer is the status of axillary lymph nodes. The aim of this study was to evaluate the diagnostic accuracy of preoperative magnetic resonance imaging (MRI) for metastatic axillary lymph node in breast cancer cases with post-operative sentinel lymph node biopsy (SLNB) results. MATERIALS AND METHODS Women aged between 21 and...
