The purpose of this research study is to find out more about distinguishing between cancerous and non-cancerous breast cancer cells at the edges of tumors. Using an FDA approved device to remove tumors, this device will be tested to see if it causes less tissue damage and therefore makes it easier to examine the tumor and make sure it is all excised. The tumors will be excised by standard surgical technique, and then the effects of the device on the removed tissues will be studied.
Breast conservation therapy (BCT) is the standard surgical treatment for breast cancer. The goal of BCT is total excision of the malignant lesion while simultaneously preserving the cosmetic appearance and functionality of the breast. Despite advances in technique and pathologic analysis; however, 20-50% of malignant breast lump excisions have cancer present to the edge of the excision margin (defined as a "positive" margin). Excisions that are found to be margin positive require a secondary excision; however, in these cases residual disease is found to be present in only 40-70% of cases. Some researchers have hypothesized that re-excision was unnecessary in a certain percentage of cases. Currently there are no routinely utilized method for intra-operative interpretation of surgical margins. Touch preps or imprint cytology has been used in the past in some centers but it is not used routinely because an experienced cytopathologist is needed to correctly interpret the slides.
The standard of care to evaluate surgical margins is based on permanent section. Margins are considered negative if there is greater than 1 mm of normal tissue between cancer cells to the excised surface. Many factors for this discrepancy have been postulated, including artifact associated with the inking process and with electrosurgery induced damage of the margin during excision (thermal injury); therefore, creating a "false positive" impression of tumor cells present at surgical margins. We propose a clinical study to evaluate the effects of thermal injury in breast cancer excision using traditional electrosurgery (i.e., the "Bovie") compared to the pulsed RF technology with the PEAK PlasmaBlade. We hypothesize that the PlasmaBlade will impart less thermal injury to the incised breast tissue (malignant and normal) and will increase the specificity of the margin status. The majority of breast cancers are removed by traditional electrocautery. We are just starting to utilize this new technology for soft tissue dissection at UCSD.
The PEAK PlasmaBlade is a family of disposable surgical cutting and coagulation devices that offer the exacting control of a scalpel and the bleeding control of traditional electrosurgery without extensive collateral damage. The PlasmaBlade is based on proprietary pulsed plasma technology. This technology represents an evolutionary leap in the advancement of radiofrequency surgical technologies, which originated with traditional electrosurgery and progressed to plasma-mediated energy devices. The PlasmaBlade tissue dissection devices are FDA-cleared and commercially available.

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
