NCT04568941

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Identification rates of sentinel lymph node biopsy

    Identification rate of SLNB between three groups

    1 year

Secondary Outcomes (2)

  • Identification numbers of sentinel lymph node biopsy

    1 year

  • fase-negative rates of sentinel lymph node biopsy

    1 year

Study Arms (3)

Preoperative Vacuum-Assisted Biopsy

EXPERIMENTAL

Preoperative vacuum-assisted biopsy was performed within 10 days before final surgery. The tumor were excised almost.

Behavioral: Vacuum-Assisted Biopsy

Preoperative Core Needle Biopsy

EXPERIMENTAL

Preoperative core needle biopsy was performed within 10 days before final surgery. The needle biopsy were performed with 3 needles.

Behavioral: Core Needle Biopsy

Intraoperative Excisional Biopsy

EXPERIMENTAL

The tumor was excised intraoperatively.

Behavioral: Intraoperative Excisional Biopsy
