Phase II Trial of Five-Fraction Accelerated Partial Breast Irradiation Using Noninvasive Image-Guided Breast Brachytherapy.

PURPOSE/OBJECTIVE(S): NIBB has potential advantages over other APBI techniques by delivering highly conformal radiation with minimal collateral dose to the heart and lung compared with external beam techniques, but unlike other brachytherapy techniques NIBB is non-invasive. Previous data has shown encouraging outcomes using a 10-fraction regimen. To improve efficiency, convenience, and cost, reduction in the fraction number is desirable. Final results of a prospective phase II trial are reported. MATERIALS/METHODS: NIBB APBI was delivered using 28.5Gy in 5 fractions daily over 1 week. Patient eligibility criteria required: invasive carcinoma ≤2.0 cm or DCIS ≤3.0 cm, ER positive (if invasive), lymph node negative, LVI absent, and lumpectomy with margins negative by 2mm. The primary endpoint was grade ≥ 2 subcutaneous fibrosis/induration <30%. Secondary endpoints included any late toxicity, cosmetic outcome, and local control. RESULTS: 40 patients were treated with a median follow-up of 59.7 months. The mean age was 67 years (50-89 years) and tumor size was 1.0cm (0.3-2.0cm). 80% had invasive carcinoma. The mean breast separation with compression was 6.7cm (3.5-8.9cm). The 5-year actuarial local control was 96.6% and overall survival was 96.9%. Grade 2 and 3 late toxicities were 15% and 0%, respectively. The rate of grade 2 subcutaneous fibrosis/induration was 2.5% (+/-2.5%) meeting the study's primary endpoint. The most common late toxicity of any grade was skin telangiectasia; 22.5% grade 1 and 15% grade 2. Only breast separation was associated with telangiectasia risk, p=0.002. Overall cosmetic outcome was excellent, good, and fair/poor in 75%, 25%, and 0%, respectively. CONCLUSIONS: NIBB APBI delivered in 5 fractions results in a low rate of late toxicity and a high rate of good/excellent cosmetic outcomes. Telangiectasia risk can be minimized by keeping breast separation ≤7.0cm. The local failure rate was appropriately low. Further investigation of this technique is warranted.

Bloody nipple discharge due to intraductal papilloma in an adolescent girl.

An early adolescent girl was referred to our breast surgery clinic with multiple right-sided breast masses and several months of unilateral bloody nipple discharge. MRI demonstrated multiple enhancing masses in the right breast with intrinsic hypertensive T1 signal of the ducts extending to the nipple. A biopsy showed partially sclerosed intraductal papillomas without atypia or malignancy. Following extensive counselling with the patient and her family, two palpable breast masses and a single central breast duct responsible for bloody nipple discharge were fully excised. Histopathological analysis showed unique overlapping features of resembling intraductal papilloma, nipple adenoma and fibroadenomas. The patient has had resolution of her bloody nipple discharge and excellent cosmetic outcomes post-surgery. Intraductal papilloma is rare in the adolescent population and the risk of concurrent and future malignancy is not well established. Thus, a tailored approach to the work-up and management of paediatric breast masses is essential.

College Undergraduates in the Operating Room: an Educational Model for Early Surgical Education.

Undergraduate pre-medical education in the USA has not traditionally offered opportunities for hands-on surgical education to college-level students. The absence of exposure has been studied, but an educational model to remedy this has not been shared. This course was designed to share a replicable model for college surgical education.

Phase 2 Trial of Accelerated Partial Breast Irradiation (APBI) Using Noninvasive Image Guided Breast Brachytherapy (NIBB).

PURPOSE: Noninvasive image guided breast brachytherapy (NIBB) is a novel approach to delivery of accelerated partial breast irradiation (APBI) that may hold advantages over established techniques. NIBB is not invasive but maintains a high level of precision by using breast immobilization via breast compression and image guidance; it therefore does not require large planning tumor volume margins. We present the primary outcomes of this prospective phase 2 study (BrUOG Br-251). METHODS AND MATERIALS: Eligible patients with early-stage breast cancer underwent NIBB APBI using a dose 34 Gy in 10 fractions delivered daily or twice a day. Treatment was delivered using an Ir-192 high-dose-rate source via specialized applicators. Two orthogonal treatment axes were used for each fraction. The primary endpoints were late toxicity and cosmesis assessed at 2 and 5 years. Toxicity was assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events v3.0. Cosmesis was assessed using the NRG/Radiation Therapy Oncology Group scale. Ipsilateral breast tumor recurrence was defined as any recurrence or new primary in the treated breast. RESULTS: Forty patients underwent protocol treatment. Median patient age was 68 years (50-92 years). Mean tumor size was 1.1 cm (0.3-3.0 cm). Among the cohort, 62.5% had invasive carcinoma and 37.5% had ductal carcinoma in situ. Thirty-nine percent elected to receive hormone therapy. No grade ≥3 late toxicities were observed at any time point. Grade 2 toxicity was 5% and 10% at 2 and 5 years, respectively. Telangiectasia grade 1 and 2 occurred in 27.5% and 5%, respectively. Breast separation of >7 cm was associated with telangiectasia (P < .01). The rate of good to excellent cosmetic outcome was 95% at 2 years and 100% at 5 years. With a median follow-up of 68 months, the actuarial 5-year freedom from ipsilateral breast tumor recurrence was 93.3% (±4.8%), and overall survival was 93.7% (±4.4%). CONCLUSIONS: NIBB to deliver APBI is well tolerated with a low incidence of significant late toxicity and has favorable cosmetic outcomes. Continued evaluation of the NIBB APBI technique in a larger cohort is warranted.

Distress: Characterizing What Causes the Thermometer to Shift in Patients with Newly Diagnosed Breast Cancer Attending a Multidisciplinary Clinic.

BACKGROUND: A diagnosis of breast cancer (BC) can result in multifactorial stress. If not addressed, distress can have a negative impact on outcomes. The experience of patients with newly diagnosed BC has not been sufficiently investigated. This study characterizes distress among new patients in a multidisciplinary care (MDC) clinic. The study aimed to determine the degree of distress at presentation, to characterize the sources, and to evaluate the impact of an MDC visit. METHODS: A retrospective review was performed from January 2015 to November 2017. Charts were accessed for demographics, tumor characteristics, and treatment data. Distress scores (DS) and problems as captured using the National Comprehensive Cancer Network (NCCN) Distress Thermometer were completed before evaluation and in a subgroup after an MDC visit. Predictors of severe distress (DS ≥4) were investigated using multivariable logistic regression. The paired t test was used to determine the impact of an MDC visit. RESULTS: The mean initial DS (n = 474) was 4.98. The top four sources of distress were worry, anxiety, fears, and sadness. Age younger than 65 years was significantly associated with a higher DS at presentation (p < 0.003). Among the patients queried before and after MDC (n = 137), a significant reduction in distress was identified (5.58-2.94; p < 0.0005). CONCLUSIONS: Severe distress was found in 66 % of the patients with a recent diagnosis of BC, with younger age related to higher distress scores at presentation. Emotional stressors were the predominant factors accounting for distress. A same-day MDC visit was associated with a significant reduction in DS. These data indicate the importance and feasibility of proactively screening patients. Our research lends support to the value of multidisciplinary evaluation in this setting.

Diffuse dermal angiomatosis mimicking inflammatory breast carcinoma.

Diffuse dermal angiomatosis (DDA) is a rare pathologically distinct subtype of reactive angioendotheliomatosis. In the literature, few biopsy-proven cases involving breast skin have been reported. We present a case of a 49-year-old female who presented with an indurated, erythematous, weeping, puckered and tender lesion with focal ulceration. Mammography demonstrated diffuse cutaneous and trabecular thickening concerning for inflammatory breast carcinoma. A punch biopsy demonstrated findings consistent with DDA. To our knowledge, this is the first reported case of DDA mimicking inflammatory carcinoma of the breast by clinical and radiologic examination.

The rationale, technique, and feasibility of partial breast irradiation using noninvasive image-guided breast brachytherapy.

PURPOSE: Noninvasive image-guided breast brachytherapy (NIBB) is a novel approach to deliver accelerated partial breast irradiation (APBI). NIBB is noninvasive, yet maintains a high degree of precision by using breast immobilization and image guidance. This makes NIBB an attractive alternative to existing APBI techniques. METHODS AND MATERIALS: Forty patients were enrolled to an institutional review board-approved prospective clinical trial evaluating APBI using NIBB. The NIBB technique is described in detail. Briefly, patients were treated with the breast compressed and immobilized sequentially in two orthogonal axes for each fraction. Radiation was delivered using collimated emissions from a high-dose-rate iridium-192 source via specialized applicators. The prescribed dose was 34.0 Gy in 10 fractions. Feasibility and tolerability of treatment were assessed. RESULTS: All patients completed protocol treatment. The median age was 68 years. Sixty-three percent of patients had invasive carcinoma, and 37% had ductal carcinoma in situ. All were node negative. Ninety-three percent of patients were postmenopausal. Mean tumor size, tumor bed volume, and breast volume were 1.1 cm, 22.4 cc, and 1591 cc, respectively. NIBB treatment was well tolerated. Median patient-reported discomfort was 1 on a 10-point pain scale. Treatment delivery times were reasonable. The average treatment time per axis was 14 min (5-20 min), and the average time from start of first treatment axis to completion of orthogonal axis was 43 min (30-63 min). Acute skin toxicity was Grade 0, 1, and 2 in 20%, 53%, and 28% of patients, respectively. There were no Grade 3 or greater acute toxicities observed. CONCLUSIONS: NIBB holds promise as an alternative method to deliver APBI. NIBB is feasible and well tolerated by patients. Further investigation of NIBB to deliver APBI is warranted.

Sex, intimacy, and the gynecologic oncologists: survey results of the New England Association of Gynecologic Oncologists (NEAGO).

Sexuality is an important aspect of life and is often affected in patients diagnosed with cancer. For women, estimates of sexual dysfunction range from 40 to 100%. In light of these statistics, we were interested in determining the comfort level and practice of specialists in gynecologic oncology as it relates to taking a sexual history and addressing related concerns by conducting a survey of the New England Association of Gynecologic Oncologists (NEAGO). Our results show that although nearly all respondents felt comfortable addressing sexual problems in their patients, less than half took a sexual history in new patients and 80% did not feel there was sufficient time to devote to exploring sexual issues. The results of our survey suggest that aspects of sexual dysfunction in women with gynecologic cancer may be neglected by gynecologic oncology providers. This encourages cancer programs to develop formal resources for women with questions regarding sexuality following a diagnosis of cancer.
