Newly diagnosed breast cancer patients choose bilateral mastectomy over breast-conserving surgery when testing positive for a BRCA1/2 mutation.
In women diagnosed with breast cancer and testing positive for a BRCA1/2 mutation, decisions as to whether to undergo prophylactic risk-reduction surgery may differ from those women who test positive in a presymptomatic phase. Eighty-four women were identified who had undergone genetic testing at the time of breast cancer diagnosis. The study group consisted of 46 of these women who had initially undergone breast-conserving surgery. Eight patients (17.4%) tested positive for a mutation. Seven of the eight underwent bilateral prophylactic mastectomy prior to receiving radiation therapy. The only patient not undergoing bilateral mastectomy was awaiting liver transplant. Women who are candidates for breast-conserving surgery and who test positive for a breast cancer gene mutation choose mastectomy over surveillance.

A comparison of methylene blue and lymphazurin in breast cancer sentinel node mapping.
BACKGROUND: When lymphazurin became unavailable to our institution, we elected to employ methylene blue to perform sentinel node mapping for patients with breast cancer. The purpose of this study was to compare methylene blue and lymphazurin for performing sentinel node mapping for breast cancer. METHODS: We evaluated our sentinel node mapping experience from April 1, 2001 to March 31, 2002. Patients were divided into two groups based on the dye used for lymphatic mapping. The two groups were compared to evaluate the results of the sentinel node mapping procedure. RESULTS: During the study period a total of 199 patients were evaluated with sentinel node mapping, 87 with lymphazurin and 112 with methylene blue. The two groups were similar in demonstrating the success of the sentinel node procedure, nodes identified per case, and technique used for node identification (colloid or dye, or both). CONCLUSIONS: In our initial experience, methylene blue appears to be equivalent to lymphazurin for sentinel node mapping in breast cancer.

Postmastectomy radiation in patients with four or more positive nodes.
Postmastectomy radiotherapy (PMR), a local therapeutic modality, is recommended to treat breast cancer patients with multiple involved axillary lymph nodes (a marker of increased systemic risk). Bothered by this conceptually flawed treatment approach we evaluated the impact of PMR on the treatment of women with four or more involved axillary lymph nodes. We identified 1164 patients treated from 1982 through 1999 with mastectomy. We reviewed the records of the 223 who demonstrated four or more positive axillary lymph nodes. Of these 128 were treated by mastectomy only and 95 by PMR. The mastectomy-only group demonstrated a mean tumor size of 3.5 cm, a median of seven axillary nodes involved, and a median of 24.9 nodes harvested. The PMR group had a mean tumor size of 4.3 cm with nine positive nodes out of a median total of 23.3 harvested. The difference in mean tumor size was statistically significant (P = 0.01). The locoregional recurrence (10.9% vs 12.6%), distant recurrence rates (42.2% vs 35.8%), and 5-year survival (51% vs 55%) were not statistically different between the mastectomy-only group versus the PMR group, respectively. Adding PMR to breast cancer treatment demonstrated no improvement in outcome. Despite limitations of this retrospective study the results strongly support evaluation of PMR by a high-quality randomized prospective trial.

Initial experience with surgical treatment planning in the newly diagnosed breast cancer patient at high risk for BRCA-1 or BRCA-2 mutation.
Despite an abundance of information available for dealing with patients with BRCA-1 and BRCA-2 mutations, little guidance is available to assist the surgeon in dealing with the genetically high-risk patient recently diagnosed with breast cancer. A retrospective review was undertaken of 170 patients who underwent genetic counseling and testing over a 3-year period from March 2000 to March 2003. Forty-three of the 170 patients tested were diagnosed with breast cancer prior to genetic testing. Nine patients (20.9%) tested positive for a deleterious mutation. Fifty-eight percent underwent genetic counseling prior to definitive cancer surgery. Five of the 25 patients who underwent lumpectomy tested positive for a deleterious mutation. Testing results became available during systemic therapy or radiation was delayed until results were known. After counseling, all five patients testing positive went on to bilateral prophylactic mastectomy and reconstruction. None had radiation therapy. Because of a strong family history, eight patients elected to undergo prophylactic mastectomy and reconstruction prior to obtaining genetic test results; and despite compelling histories, all eight tested negative for a mutation. Treatment algorithms are developed to manage patients that are first discovered to be at high risk for a BRCA-1 or BRCA-2 mutation at the time they are diagnosed with breast cancer. Patients diagnosed with breast cancer who are discovered to be at high risk for a genetic mutation should undergo counseling prior to definitive surgery. This maximizes the time that patients have to consider options for prophylaxis and monitoring should their test be positive. It also prevents women who would otherwise be candidates for breast preservation from undergoing unnecessary radiation therapy should they chose prophylactic mastectomy in the face of a positive test.

Postlumpectomy Insertion of the MammoSite brachytherapy device using the scar entry technique: initial experience and technical considerations.
For women undergoing breast-conserving surgery, recent reports suggest that in selected cases accelerated partial breast irradiation may yield results equal to that of whole breast irradiation. Over 31 months, 19 patients underwent accelerated partial breast irradiation using the MammoSite as the sole radiation treatment following breast-conserving surgery. Seventeen patients had the MammoSite inserted postoperatively using the scar entry technique (SET). Treatments were delivered using high dose rate iridium 192 given twice a day for 5 days. Three complications (two minor, one major) occurred. Late radiation morbidity and overall cosmetic results were evaluated. Eighty percent of patients had either no change from baseline or slight change in skin pigment. More than 90% had good or excellent overall cosmetic outcomes. Patients undergoing accelerated partial breast irradiation with the MammoSite inserted using SET had excellent overall cosmetic results. Advantages of the SET over intraoperative placement are presented.
