Autofluorescence and diffuse reflectance spectroscopy and spectral imaging for breast surgical margin analysis

LASERS IN SURGERY AND MEDICINE, Issue 1 2010
Matthew D. Keller MS
Abstract Background and Objective Most women with early stage breast cancer have the option of breast conserving therapy, which involves a partial mastectomy for removal of the primary tumor, usually followed by radiotherapy. The presence of tumor at or near the margin is strongly correlated with the risk of local tumor recurrence, so there is a need for a non-invasive, real-time tool to evaluate margin status. This study examined the use of autofluorescence and diffuse reflectance spectroscopy and spectral imaging to evaluate margin status intraoperatively. Materials and Methods Spectral measurements were taken from the surface of the tissue mass immediately following removal during partial mastectomies and/or from tissues immediately after sectioning by surgical pathology. A total of 145 normal spectra were obtained from 28 patients, and 34 tumor spectra were obtained from 12 patients. Results After correlation with histopathology, a multivariate statistical algorithm classified the spectra as normal (negative margins) or tumor (positive margins) with 85% sensitivity and 96% specificity. A separate algorithm achieved 100% classification between neo-adjuvant chemotherapy-treated tissues and non-treated tissues. Fluorescence and reflectance-based spectral images were able to demarcate a calcified lesion on the surface of a resected specimen as well. Conclusion Fluorescence and reflectance spectroscopy could be a valuable tool for examining the superficial margin status of excised breast tumor specimens, particularly in the form of spectral imaging to examine entire margins in a single acquisition.

Oncological and Aesthetic Considerations of Conservational Surgery for Multifocal/Multicentric Breast Cancer

THE BREAST JOURNAL, Issue 3 2010
Neill Patani BSc
Abstract:, Conventional indications for mastectomy (MX) reflect circumstances where breast conserving therapy (BCT) could compromise oncological or cosmetic outcome. MX continues to be recommended for the majority of women with multiple lesions within the same breast. In this article, we review the oncological safety and aesthetic considerations of BCT in the context of multifocal (MF) or multicentric (MC) breast cancer. Literature review facilitated by Medline and PubMed databases. Published studies have reported divergent results regarding the oncological adequacy of BCT in the management of MF or MC disease. Earlier studies demonstrated high rates of local recurrence (LR) for BCT. More recent series have found BCT to be comparable to MX in terms of LR, distant failure, disease free and overall survival. Few studies have adequately evaluated cosmetic outcomes following BCT for MF or MC breast cancer. Contemporary oncoplastic techniques have extended the clinical utility of BCT and are of particular relevance to breast conservation in the context of MF or MC lesions. Appropriate case selection, preoperative oncological and aesthetic planning, satisfactory clearance of the surgical margins and adjuvant radiotherapy are of paramount importance. In the absence of level-1 guidance concerning the management of women with MF or MC disease, each case requires discussion with regard to tumor and patient related factors in the context of the multidisciplinary team. In selected patients with MF or MC disease, BCT is oncologically safe and cosmetically acceptable. Uniformity of practice and the establishment of a standard of care will require an evidence-base from prospective studies. [source]
