Brief Summary

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

This is a retrospective, multicentric cohort study of patient cases with cT1-3, N0 early breast cancer, who previously had intraoperative sentinel lymph node (SLN) evaluation by one-step nucleic acid amplification (OSNA) assay with a complete axillary dissection.

The aim of the present study is to assess the intraoperative positive SLN total tumor load (TTL) obtained from the OSNA assay and to determine whether this TTL predicts non-SLN metastasis in patients with clinically node-negative early-stage breast cancer.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Pathologically confirmed invasive breast carcinoma
* Stage T1-3,N0 evaluated by physical exam or imaging according to AJCC v.7 and best clinical local practices
* Intraoperative evaluation of sentinel lymph node (SLN) by OSNA

* presence/absence of lymphovascular invasion
* total number of sentinel and non-sentinel lymph nodes dissected during surgery
* total number of positive and negative sentinel and non-sentinel lymph nodes, \*size of the metastasis in both sentinel and non-sentinel lymph nodes
* total tumoral load in each sentinel lymph node, expressed as number of CK19 mRNA copies per microliter.

Exclusion Criteria
