RESUMO
BACKGROUND: Lymphedema prevention surgery (LPS), which identifies, preserves, and restores lymphatic flow via lymphaticovenous bypasses (LVB), has demonstrated potential to decrease lymphedema in breast cancer patients requiring axillary lymph node dissection. Implementing this new operating technique requires additional operating room (OR) time and coordination. This study sought to evaluate the improvement of LPS technique and OR duration over time. METHODS: A prospective database of patients who underwent LPS at our institution from 2016 to 2019 was queried. Type of breast and reconstruction surgery, number of LVB performed, and OR times were collected. LPS details were compared by surgical group and year performed. RESULTS: Ninety-four patients underwent LPS, and 88 had complete OR time data available for analysis. Average age was 51 years, body mass index of 28, with an average of 15 lymph nodes removed. Reconstructive treatment groups included prosthetic reconstruction 56% (49), oncoplastic reduction 10% (9), and no reconstruction 34% (30). The number of patients undergoing LPS increased significantly from 2016 to 2019, and average number of LVB per patient doubled. In patients without reconstruction, the average time for LPS improved significantly from 212 to 87 min from 2016 to 2019 (p = 0.015) and similarly in patients undergoing LPS with prosthetic reconstruction from 238 to 160 min (p = 0.022). CONCLUSIONS: LVB is an emerging surgical lymphedema prevention technique. While requiring additional surgical time, our results show that with refinement of technique, over 4 years, we were able to perform double the number of LVB per patient in half the OR time.

Adjuvant radiation therapy has been associated with improved local control following breast-conserving surgery. Traditionally, treatment has been delivered with whole breast irradiation over 3-6 weeks or partial breast irradiation over 1-3 weeks. However, intraoperative radiation therapy (IORT) has emerged as a technique that delivers a single dose of radiotherapy at the time of surgery for early-stage breast cancers. We report initial outcomes and acute toxicities with intraoperative radiation from a single institution. Patients with DCIS or Stage I-II breast cancer who underwent lumpectomy and sentinel lymph node biopsy (nodal sampling excluded in some cases) were included. All patients in this analysis were treated with IORT as at the time of surgery, 20 Gy in 1 fraction with 50 kV x-ray. Patients were treated at a single institution between 2011 and 2019. Follow-up was per standard institutional protocol. Two hundred and one patients were included in the analysis, with a median follow-up of 23 months (range: 0-73 months). Median age was 71 years old. Overall, 4 (2.0%) patients had DCIS, 186 (92.5%) patients had Stage 1 disease, and 11 patients had (5.5%) Stage 2 disease. All patients were estrogen receptor-positive, 175 (87.9%) progesterone receptor-positive, and 1 (0.5%) HER2 amplified. The crude rate of local recurrence was 2.0% (n = 4) and distant metastasis rate was 0.5% (n = 1). The rate of arm lymphedema was 0.5% (n = 1) and chronic telangiectasia rate was 1.1% (n = 2). Intraoperative radiation therapy, in a cohort of low-risk patients, demonstrated low rates of recurrence and reproducibility in a multi-disciplinary setting. Further follow-up, analysis of patient satisfaction and cosmesis, and comparison to whole breast irradiation and partial breast techniques is necessary in order to further validate these findings.

BACKGROUND: No clear standards regarding number or type of narcotics for adequate postoperative pain control have been established in breast surgery. The authors of this study reviewed their opioid-prescribing patterns and implemented a planned change, evaluated the effectiveness of a departmental practice adjustment, and prospectively evaluated patient narcotic usage. METHODS: The narcotic prescriptions for 100 consecutive breast surgery patients were reviewed to establish baseline postoperative narcotic-prescribing patterns. The median of narcotics prescribed was used to educate surgeons and implement a planned change in prescribing practices. Data on narcotic prescriptions for 100 consecutive breast surgery patients then were prospectively collected, and the number of pain pills the patients actually took after discharge was recorded using a standardized template. RESULTS: A baseline review of narcotic-prescribing practices showed that the median number of pills given was 15 for excisional biopsy/lumpectomy, 20 for mastectomy, and 28 for mastectomy with reconstruction. After departmental education, the median number decreased to 10 for excisional biopsy/lumpectomy (p < 0.01) and 25 for mastectomy with reconstruction (p < 0.01). Prospective recording of patient usage compared with the prescribed number of pills indicated that most prescribed pills were not used, with the excisional biopsy or lumpectomy patients using a median of 1 pill (p < 0.01), the mastectomy patients using a median of 3 pills (p < 0.01), and the mastectomy with reconstruction patients using a median of 18 pills (p < 0.01) postoperatively. Only three patients, all of whom had breast reconstruction performed, required a refill of narcotics. CONCLUSIONS: Successful reduction in narcotic prescriptions can be implemented for breast surgery patients. Further reductions in narcotic prescriptions may be feasible based on prospective collected patient usage.

Granulomatous mastitis is an uncommon inflammatory disease that typically presents with painful breast lesions. Recent publications have brought to light a specific subset of granulomatous mastitis patients with a distinct histological pattern of disease termed, "cystic neutrophilic granulomatous mastitis" (CNGM). Although many cases of granulomatous lobular mastitis have been thought to be idiopathic, this rare subset of an uncommon disease has been linked to infections with Corynebacterium species. Herein, a cohort of CNGM patients from a large, tertiary care, North-American, academic medical center is presented. Correlative demographic, clinical, radiographic, pathologic, microbiologic, management, and outcomes data are provided. Collaborative communication between specialists to accurately diagnose and manage these patients is essential to decreasing potential morbidity.

BACKGROUND: Twitter social media is being used to disseminate medical meeting information. Meeting attendees and other interested parties have the ability to follow and participate in conversations related to meeting content. We analyzed Twitter activity generated from the 2013-2016 American Society of Breast Surgeons Annual Meetings. METHODS: The Symplur Signals database was used to determine number of tweets, tweets per user, and impressions for each meeting. The number of unique physicians, patients/caregivers/advocates, and industry participants was determined. Physician tweeters were cross-referenced with membership and attendance rosters. Tweet transcripts were analyzed for content and tweets were categorized as either scientific, social, administrative, industry promotion, or irrelevant. RESULTS: From 2013 to 2016, the number of tweets increased by 600 %, the number of Twitter users increased by 450 %, and the number of physician tweeters increased by 457 %. The number of impressions (tweets × followers) increased from more than 3.5 million to almost 20.5 million, an increase of 469 %. The majority of tweets were informative (70-80 %); social tweets ranged from 13 to 23 %. A small percentage (3-6 %) of tweets were related to administrative matters. There were very few industry or irrelevant tweets. CONCLUSIONS: Twitter social media use at the American Society of Breast Surgeons annual meeting showed a substantial increase during the time period evaluated. The use of Twitter during professional meetings is a tremendous opportunity to share information. The authors feel that medical conference organizers should encourage Twitter participation and should be educating attendees on the proper use of Twitter.

Background: Gender disparities in academic promotion and leadership are well documented. Scholarly impact is essential for promotion. The Hirsch-index (h-index) is a measure of impact using number of publications and citations. We sought to (i) evaluate breast surgery fellowship faculty in North America by academic rank and research impact using the h-index, (ii) determine whether there is a gender difference in scholarly productivity, and (iii) determine the relationship between academic rank, h-index, and gender. Materials and Methods: A retrospective cross-sectional study of h-index and academic rank disparity in breast surgery faculty by gender was performed. We reviewed the faculty of Society of Surgical Oncology-accredited breast surgery fellowships in February 2019. Rank, gender, academic appointment, years in practice, program directorship, National Cancer Institute-designated cancer center association, size of the program, and h-index (via Scopus) were recorded. Univariate and multiple linear regression analyses were performed. Results: Fifty-two programs were identified, and 209 faculty had an h-index. Of them, 69.9% were women and 30.1% were men. h-index increased with academic rank although there was considerable overlap between ranks. Women were underrepresented at the professor level (46.4%), but accounted for the majority of assistant professors (91.5%, p < 0.001), and program directors (70.7%). Men professors had a significantly higher mean h-index than women professors, p < 0.001. However, women associate professors had a higher mean h-index than men, but this did not reach significance. Conclusions: Mean h-index increased with increasing rank among breast surgery faculty for both genders. Average h-index was significantly higher for men professors compared to women professors. No significant gender difference in h-index was found for assistant professors. For associate professors, h-index for women was higher than for men. Women are underrepresented at higher academic ranks despite forming the majority of breast surgical teaching faculty.

Background: Lymphedema is a complication of breast cancer therapy associated with substantial anxiety. We designed a prospective, randomized study to assess the psychosocial impact of different surveillance methods for lymphedema. Methods and Results: In this open-label study of 38 women undergoing breast cancer surgery, we screened for lymphedema using traditional volumetric measurements (circumferential readings from the wrist to the axilla) versus bioimpedance spectroscopy (BIS) using electric current. The primary outcome measure was total anxiety measured by the Beck Anxiety Inventory, a 21-item questionnaire administered at preoperative, 6-week, 3-month, and 6-month postoperative visits (range 0-63 points). Outcome metrics were compared after adjustment for baseline anxiety. There were no differences in clinical characteristics or cancer therapies between groups, except for more reoperation for positive surgical margins in the BIS patients (5% vs. 32%, p = 0.036). Baseline anxiety, depression, and associated medical therapies were similar as well. Only one woman in each group developed lymphedema during the study. Anxiety was higher in the BIS group at baseline (mean Beck score 12.2 vs. 7.2, p < 0.001), but anxiety levels gradually declined by the end of the 6-month study in both groups, with no differences in adjusted anxiety scores between the two groups at any time point during follow-up (all p = NS). Conclusions: In this pilot study of women scheduled for breast cancer surgery, most subjects reported mild anxiety at baseline, and anxiety levels fell during continued lymphedema surveillance visits. There was no difference in patient-reported anxiety when surveillance was performed using standard volumetric versus BIS measurements.

BACKGROUND: Near infrared (NIR) fluorescence imaging is an emerging modality that can enable real-time image-guided procedures. Indocyanine green (ICG) is an FDA-approved, inexpensive, and widely available NIR dye. We hypothesized that axillary lymphatic mapping with ICG is equivalent to lymphatic mapping with technetium 99m (99mTc) in breast cancer patients. STUDY DESIGN: Breast cancer patients (cT1-2, N0) were prospectively enrolled. Patients underwent lymphatic mapping with 99mTc preoperatively and ICG mapping intraoperatively (0.8 mL). Sentinel lymph node (SLN) biopsy was guided by NIR camera and gamma probe. Rate of failed mapping, number of SLNs identified, and rate of identifying pathologically positive SLNs were compared between the 2 techniques (p < 0.05 was considered statistically significant). RESULTS: Ninety-two female patients were enrolled (median age 59 years). Mean transit time from ICG injection in the breast to localization in the axilla was 5 minutes (range 2 to 29 minutes). No adverse reactions to ICG were noted. Mean number of SLNs identified with ICG and 99mTc was 2.4 (SD 1.42) and 2.2 (SD 1.23), respectively (p = 0.34). Pathologically positive SLNs were identified in 18 (19.8%) patients. A total of 24 pathologically positive SLNs in 18 patients were identified by ICG in 24 of 24 (100%) patients and by 99mTc in 23 of 24 (96%) patients (p = 0.99). CONCLUSIONS: Indocyanine green with NIR fluorescence imaging can be safely and efficiently used for real-time intraoperative lymphatic mapping in breast cancer patients. Indocyanine green performs similarly to 99mTc with regard to the number of SLNs identified, rate of failed mapping, and identification of pathologically positive SLNs.

Background: To increase awareness, search for solutions, and drive change, disparity-related research needs to be strategically disseminated. This study aimed to quantify whether a social media strategy could: (1) amplify dissemination of gender equity-related articles and (2) collect proposed solutions to gender equity issues. Methods: In April 2018, eight published journal articles covering separate gender equity issues were presented in a 1-hour Twitter chat hosted by Physician's Weekly. Metrics data were collected before, during, and after the chat. During the chat, one question related to each article was tweeted at a time. Qualitative data were extracted from responses and evaluated for thematic content. Results: In the 16-hour period during and following the chat, we tallied 1500 tweets from 294 participants and 8.6 million impressions (potential views). The Altmetric Attention Score of each article increased (average, 126.5 points; range, 91-208 points). Within the respective journal, the Altmetric Rank of seven articles improved (range, 3 to ≥19), while the eighth maintained its #1 rank. The one article for which share and download data were available experienced a 729% increase in shares following prechat posts and another 113% bump after the chat, a 1667% increase overall (n = 45-795). Similarly, downloads, and presumably reads, increased 712% following prechat posts and another 47% bump after the chat, a 1093% increase overall (n = 394-4700). We tallied 181 potential solutions to the eight gender equity-related questions. Conclusion: Our results demonstrate that social media can be used strategically to increase the dissemination of research articles and collect solution-focused feedback.
