  Purpose

The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System for patients receiving Sentinel Lymph Node biopsies after receiving neoadjuvant hormonal/chemotherapy as compared to permanent section Hematoxylin and Eosin (H&E) and Immuno-histochemistry (IHC) staining.

Primary Outcome Measures:
  • Prospectively assess the performance of the OSNA Breast Cancer System for the detection of SLN metastasis in subjects treated with neoadjuvant therapy prior to SLN biopsy by comparing results with standard histopathology evaluation. [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Compare performance of the OSNA Breast Cancer System to intraoperative frozen section methods (mandatory) and imprint cytology methods (optional) with standard histopathology results from permanent sections. [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • Correlate OSNA results and histology results with the status of non‐sentinel lymph nodes. [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • Determine incidence of breast cancer recurrence in axillary lymph nodes and distant organs within 5 years in study subjects (Phase II). [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Samples of the tissue homogenate will be retained and may be used for for further testing.

OSNA Breast Cancer System

For in vitro diagnostic use only.

The OSNA Breast Cancer System is an automated semi-quantitative, in vitro diagnostic test for the rapid detection of greater than (>) 0.2 mm metastases in nodal tissue removed from sentinel lymph node biopsies of breast cancer patients. Results from the assay can be used to guide the intra-operative or post-operative decision to remove additional lymph nodes and to aid in patient staging. An assay positive + or ++ result indicates the presence of metastasis (> 0.2 mm). An assay positive ++ result predicts the presence of macrometastasis (> 2 mm).

Post-operative histological evaluation of permanent sections of the tissue specimen, in accordance with usual diagnostic practice and using the Sysmex lymph node cutting scheme, is required.


  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

Patients with a previous diagnosis of breast cancer scheduled for sentinel lymph node dissection after receiving neoadjuvant hormonal/chemotherapy.

Criteria

Inclusion Criteria:

  • Male or female
  • 18 years of age or older
  • Diagnosed pre‐surgically with T1‐T3 or T4 non‐inflammatory breast cancer, clinically node positive or node negative upon clinical examination
  • Scheduled for SLN biopsy after receiving neoadjuvant hormonal or chemotherapy
  • Subjects (or the subjects' legal representatives) who have read, understood (to the best of their ability) and signed the informed consent form.

Exclusion Criteria:

  • Pregnant subjects, confirmed by interview with either subject or treating physician
  • Subjects previously diagnosed with other invasive cancer. Subjects with skin cancer (basal cell and squamous cell carcinoma) may be included, except for subjects diagnosed with melanoma
  • Participation in other neoadjuvant protocols specifically requiring SLN biopsy prior to administration of neoadjuvant chemotherapy or hormonal therapy
  • Subjects who have been judged to be an inappropriate candidate by any medical care provider (e.g., surgeon, oncologist or pathologist).
