Journal ArticleDOI
The role of MRI in axillary lymph node imaging in breast cancer patients: a systematic review.
V. J. L. Kuijs,M. Moossdorff,M. Moossdorff,Robert-Jan Schipper,Robert-Jan Schipper,Regina G. H. Beets-Tan,Regina G. H. Beets-Tan,Esther M. Heuts,Kristien Keymeulen,Marjolein L. Smidt,Marjolein L. Smidt,Marc B. I. Lobbes +11 more
TL;DR: The diagnostic performance of some MRI protocols for excluding axillary lymph node metastases approaches the NPV needed to replace SLNB, however, current observations are based on studies with heterogeneous study designs and limited populations.
Journal ArticleDOI
Axillary ultrasound for preoperative nodal staging in breast cancer patients: is it of added value?
Robert-Jan Schipper,L.M. van Roozendaal,B. de Vries,Ruud M. Pijnappel,Regina G. H. Beets-Tan,Marc B. I. Lobbes,Marjolein L. Smidt +6 more
TL;DR: It could be argued that the standard performance of an axillary ultrasound in breast cancer patients is questionable; multidisciplinary discussion could guide decisions on the use of axillary ultrasounds for the individual patient.
Journal ArticleDOI
Routine use of standard breast MRI compared to axillary ultrasound for differentiating between no, limited and advanced axillary nodal disease in newly diagnosed breast cancer patients
T. J. A. van Nijnatten,E H Ploumen,Robert-Jan Schipper,B. Goorts,E H Andriessen,S. Vanwetswinkel,M Schavemaker,Patty J. Nelemans,B. de Vries,Regina G. H. Beets-Tan,Regina G. H. Beets-Tan,Marjolein L. Smidt,Marc B. I. Lobbes +12 more
TL;DR: Evaluation of axillary nodal status on standard breast MRI is comparable to dedicated axillary ultrasound in breast cancer patients, and in patients who underwent preoperative standard Breast MRI, axillary abortion is only required in case of suspicious nodal findings on MRI.
Journal ArticleDOI
The diagnostic performance of sentinel lymph node biopsy in pathologically confirmed node positive breast cancer patients after neoadjuvant systemic therapy: A systematic review and meta-analysis.
T. J. A. van Nijnatten,Robert-Jan Schipper,Marc B. I. Lobbes,Patty J. Nelemans,R.G.H. Beets-Tan,Marjolein L. Smidt +5 more
TL;DR: Based on current evidence it seems not justified to omit further axillary treatment in every clinically node positive breast cancer patients with a negative sentinel lymph node biopsy after neoadjuvant systemic therapy.
Journal ArticleDOI
Diagnostic Performance of Dedicated Axillary T2- and Diffusion-weighted MR Imaging for Nodal Staging in Breast Cancer
Robert-Jan Schipper,Marie-Louise Paiman,Regina G. H. Beets-Tan,Patricia J. Nelemans,Bart de Vries,Esther M. Heuts,Koen Van de Vijver,Kristien Keymeulen,Boudewijn Brans,Marjolein L. Smidt,Marc B. I. Lobbes +10 more
TL;DR: Dedicated high-spatial-resolution axillary T2-weighted MR imaging showed good specificity on the basis of node-by-node and patient- by-patient validation, with good interobserver agreement.
