Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to estimate the diagnostic accuracy of preoperative ultrasound-guided axillary lymph node biopsy for staging in patients with newly diagnosed breast cancer, and also to compare between ultrasound-guided fine needle aspiration cytology and core needle biopsy in their ability to detect metastatic disease in the axillary lymph nodes of patients with breast cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Axillary lymph node status is an extremely important prognostic factor in the assessment and treatment evaluation of patients with newly diagnosed breast cancer. Historically, axillary lymph node dissection (ALND) has been the reference standard for diagnosis and staging. However, this procedure can cause numerous postoperative problems, such as lymphedema , pain, impaired shoulder mobility and arm weakness. Furthermore, in this era of mammographic screening, axillary lymph node dissection yields negative results in 80%-85% of patients with T1 cancer.

Therefore, in recent years, sentinel lymph node biopsy (SNB) has replaced axillary dissection for lymph node staging at major medical centers. However, there are some practical issues to be resolved. For example, radiotracer distribution can be slow or faulty, valuable operating room time is expended, and pathologists must make quick decisions based on the analysis of frozen sections or there is the need to undergo two surgical interventions (i.e., removal of primary tumor and SNB, and in a next step completion ALND). If nodal positivity could be proven and documented preoperatively, sentinel lymph node biopsy could be bypassed and a decision will be made to perform axillary dissection, which is the standard of care in most node-positive patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with operable breast cancer

Ultrasound-guided axillary lymph nodes FNAC and\\or CNB.

Group Type OTHER

Ultrasound-guided axillary lymph nodes FNAC and\or CNB.

Intervention Type PROCEDURE

Ultrasound-guided axillary lymph node fine needle aspiration and\\or core needle biopsy of the most suspicious lymph node. If all the lymph nodes appeared similar or normal, the lymph node that is lowest in the axilla will be selected because it is considered to most likely be the sentinel node.
