Clinical Trial
Targeted Intraoperative Radiotherapy for the Management of Ductal Carcinoma In Situ of the Breast.
Multiple long-term studies have demonstrated a propensity for breast cancer recurrences to develop near the site of the original breast cancer. Recognition of this local recurrence pattern laid the foundation for the development of accelerated partial breast irradiation (APBI) approaches designed to limit the radiation treatment field to the site of the malignancy. However, there is a paucity of data regarding the efficacy of APBI in general, and intraoperative radiotherapy (IORT), in particular, for the management of ductal carcinoma in situ (DCIS). ⋯ No deaths or distant recurrences were observed. Imaging-occult DCIS is a challenge for IORT, as it is for all forms of breast-conserving therapy. Nonetheless, 91.4% of patients with DCIS were successfully managed with BCS and IORT alone, with relatively few patients requiring additional therapy.

Preoperative breast magnetic resonance imaging (MRI) use among Medicare beneficiaries with breast cancer has substantially increased from 2005 to 2009. We sought to identify factors associated with preoperative breast MRI use among women diagnosed with ductal carcinoma in situ (DCIS) or stage I-III invasive breast cancer (IBC). Using Surveillance, Epidemiology, and End Results and Medicare data from 2005 to 2009 we identified women ages 66 and older with DCIS or stage I-III IBC who underwent breast-conserving surgery or mastectomy. ⋯ Women with DCIS were more likely to receive preoperative MRI if tumors were larger (>2 cm). The likelihood of receiving preoperative breast MRI is similar for women diagnosed with DCIS and IBC. Use of MRI is more common in women with IBC for tumors that are lobular and smaller while for DCIS MRI is used for evaluation of larger lesions.

Comparative Study
Psychosocial and Sexual Well-Being Following Nipple-Sparing Mastectomy and Reconstruction.
Nipple-sparing mastectomy (NSM) is considered an oncologically safe option for select patients. As many patients are candidates for nipple-sparing or skin-sparing mastectomy (SSM), reliable patient-reported outcome data are crucial for decision-making. The objective of this study was to determine whether patient satisfaction and/or health-related quality of life (HRQOL) were improved by preservation of the nipple with NSM compared to SSM and nipple reconstruction. ⋯ There was no significant difference in the BREAST-Q physical well-being, satisfaction with breast, or satisfaction with outcome domains between the NSM and SSM groups. NSM is associated with higher psychosocial and sexual well-being compared to SSM and nipple reconstruction. Preoperative discussion of such HRQOL outcomes with patients may facilitate informed decision-making and realistic postoperative expectations.

The purpose of this study is to determine whether including breast magnetic resonance imaging (MRI) in the preoperative workup of patients with known breast cancer has an impact on mastectomy and/or re-excision rates. This is an Institutional Review Board approved HIPAA compliant retrospective study reviewing the impact MRI has on mastectomy and re-excision rates in patients with newly diagnosed breast cancer. Our study compares two groups: (i) 154 patients who did not receive preoperative MRIs and served as a control group and (ii) 96 patients who received preoperative breast MRIs. ⋯ The difference between involved and clear margins was significant as well (p = 0.002), with patients undergoing preoperative MRI more likely to have negative margins. Preoperative breast MRI significantly decreases the likelihood of involved margins as well as the need for surgical re-excision. Preoperative breast MRI does not result in a statistically significant difference in mastectomy rates, although further investigation is required to determine whether there is a trend towards statistical significance.
