Radioactive seed localization (RSL) has emerged as an alternative to wire localization (WL) in patients with nonpalpable breast cancer. Few studies have prospectively evaluated patient satisfaction and outcomes with RSL. We report the results of a randomized trial comparing RSL to WL in our community hospital. We prospectively enrolled 135 patients with nonpalpable breast cancer between 2011 and 2014. Patients were randomized to RSL or WL. Patients rated the pain and the convenience of the localization on a 5-point Likert scale. Characteristics and outcomes were compared between groups. Of 135 patients enrolled, 10 were excluded (benign pathology, palpable cancer, mastectomy, and previous ipsilateral cancer) resulting in 125 patients. Seventy patients (56%) were randomized to RSL and 55 (44%) to WL. Fewer patients in the RSL group reported moderate to severe pain during the localization procedure compared to the WL group (12% versus 26%, respectively, p = 0.058). The overall convenience of the procedure was rated as very good to excellent in 85% of RSL patients compared to 44% of WL patients (p < 0.0001). There was no difference between the volume of the main specimen (p = 0.67), volume of the first surgery (p = 0.67), or rate of positive margins (p = 0.53) between groups. RSL resulted in less severe pain and higher convenience compared to WL, with comparable excision volume and positive margin rates. High patient satisfaction with RSL provides another incentive for surgeons to strongly consider RSL as an alternative to WL.

The adoption of breast brachytherapy into clinical practice for early-stage breast cancer has increased over the last several years. Studies evaluating complication rates following treatment with brachytherapy have shown conflicting results. We compared local toxicity in patients treated with brachytherapy with those treated with whole-breast irradiation (WBI).

The NoTouch BreastScan (NTBS) is a non-invasive infrared imaging device which measures thermal gradients in breasts using dual infrared cameras and computer analysis. We evaluated NTBS as a predictor of breast cancer in patients undergoing minimally invasive biopsy. In this IRB-approved prospective trial, 121 female patients underwent NTBS prior to scheduled tissue biopsy. Twenty-two patients were excluded due to uninterpretable scans (n = 18), diagnosis of a nonprimary breast malignancy (n = 1), or no biopsy performed (n = 3) for a total of 99 patients. Five patients had bilateral breast biopsies and one patient had two ipsilateral biopsies, resulting in 105 biopsies. Patients were prospectively scanned using a high specificity mode, termed NTBS1. All 99 patients were retrospectively re-evaluated in a high sensitivity mode, NTBS2. Of 105 biopsies performed in 99 women, 33 (31.4%) were malignant and 72 (68.6%) were benign. NTBS1 demonstrated a sensitivity of 45.5% and a specificity of 88.9%. Of 94 normal contralateral breasts, 9.6% had a positive NTBS1. In the retrospective evaluation, NTBS2 demonstrated a sensitivity of 78.8% and a specificity of 48.6%. Half (50%) of the normal contralateral breasts had a positive NTBS2. NTBS does not accurately predict malignancy in women with suspicious imaging abnormalities. The higher sensitivity mode results in an unacceptable number of false positives, precluding its use. Infrared imaging did not improve the sensitivity or specificity of mammography in this clinical setting.

The American Society for Radiation Oncology (ASTRO) consensus statement (CS) provides guidelines for patient selection for accelerated partial breast irradiation (APBI) following breast conserving surgery. The purpose of this study was to evaluate recurrence rates based on ASTRO CS groupings. A single institution review of 238 early stage breast cancer patients treated with balloon-based APBI via balloon based brachytherapy demonstrated a 4-year actuarial ipsilateral breast tumor recurrence (IBTR) rate of 5.1%. There were no significant differences in the 4-year actuarial IBTR rates between the “suitable,” “cautionary,” and “unsuitable” ASTRO categories (0%, 7.2%, and 4.3%, resp.,P=0.28). ER negative tumors had higher rates of IBTR than ER positive tumors. The ASTRO groupings are poor predictors of patient outcomes. Further studies evaluating individual clinicopathologic features are needed to determine the safety of APBI in higher risk patients.

Current National Comprehensive Cancer Network guidelines recommend repeat imaging 6–12 months after a benign radiologic–pathologic concordant image-guided breast biopsy. We hypothesized that interval imaging <12 months after benign concordant biopsy has a low cancer yield and increases health care costs.
