Comparison Study of Different Tumor Biopsy Method for Sentinel Lymph Node Biopsy in Breast Cancer

October 24, 2020 updated by: Zhiyong Yu, Shandong Cancer Hospital and Institute

Randomized Controlled Trial of Comparison of Tumor Biopsy Method of Preoperative Vacuum-Assisted, Core Needle Versus Intraoperative Excisional Biopsy for Sentinel Lymph Node Biopsy in Breast Cancer

Sentinel lymph node biopsy (SLNB) has become a mainstay surgery method in breast cance, and the identified number of sentinel lymph nodes determines its accuracy for axillary status. Retrospective study indicated that preoperative tumor biopsy results in more detected sentinel lymoh nodes. The clinical trail is designed to compare the effect of three tumor biopsy methods (preoperative vacuum-assisted biopsy, core needle biopsy, and intraoperative excisional biopsy) for sentinel lymph nodes.

Study Overview

Detailed Description

OBJECTIVES:

Compare the identification rate of sentinel lymph node in breast cancer patients with different tumor biopsy methods.

Evaluate the false-negative rates of sentinel lymph nodes in patients with different tumor biopsy methods.

OUTLINE:

The patients were randomly divided into three group, vacuum-assisted biopsy, core needle biopsy, and intraoperative excisional biopsy. Preoperative vacuum-assisted biopsy and core needle biopsy were performed in 10 days before the final surgery. All patients received dual tracer (radiolabeled colloid and blue dye) guided SLNB.
