Brief Summary

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

The goal of this research is to further develop novel optical assay systems for intra operative assessment of tumor margins in partial mastectomy or mastectomy specimens.

Detailed Description

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

The goal of this research is to further develop novel optical assay systems for intra operative assessment of tumor margins in partial mastectomy or mastectomy specimens. We are seeking to establish the accuracy of first and second-generation prototypes of technologies utilizing optical spectroscopy for intra operative margin assessment in partial mastectomy or mastectomy specimens. The aims associated with this research are as follows, (1) to evaluate the device-tissue interface on reduction mammoplasty specimens from a total of 20 patients, (2) to assess random and systematic errors of the new miniature system on mastectomy specimens from a total of 40 patients (3) to test the sensitivity, and specificity of the miniature spectral imaging system for margin assessment on excised partial mastectomy or mastectomy specimens from a total of 150 patients undergoing breast conserving surgery.

Last patient's surgery took place in 2017 and recruitment remained open. Later the team encountered staffing issues; therefore the study status was updated to suspended. We recently made the decision to no longer attempt to enroll the remaining 2 subjects and focus on the data analysis only.

Eligibility Criteria

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

Inclusion Criteria

* Patients undergoing a reduction mammoplasty OR
* Patients undergoing a lumpectomy mastectomy for the treatment of an invasive or non-invasive breast malignancy
* Age \> 18
* Clinically detectable disease either by physical examination or radiographic studies
* Patients of all ethnic and gender groups will be included. Protocol accrual will be reviewed annually to include a determination of minority and gender representation. If accrual demonstrates under-representation of any group with comparison to disease incidence in that group, appropriate measures will be undertaken to increase participation of patients of that minority or gender group
* Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria

* Patients considered in "vulnerable" populations.
