RESUMO
BACKGROUND: Granulomatous mastitis (GM) is a benign, chronic, inflammatory disease lacking clear treatment guidelines. The purpose of this American Society of Breast Surgeons (ASBrS) prospective, multisite registry was to characterize the presentation of GM and identify treatment strategies associated with symptom resolution and optimal cosmesis. METHODS: ASBrS members entered data into a registry on patient demographics, treatment, symptoms, and cosmesis over a 1-year period. Initial symptoms were graded as mild, moderate, or severe. The Chi-square test and logistic regression were used to identify factors related to symptom improvement and cosmesis. RESULTS: Overall, 112 patients with a mean age of 36 years were included. More patients were Hispanic (49.1%) and from the Southwest (41.1%), and management included observation (4.5%), medical (70.5%), surgical (5.4%), or combination treatment (19.6%). Immunosuppression was used in 83 patients (74.1%), including 43 patients who received intralesional steroid injections. Patients with severe symptoms were more likely to undergo surgical intervention compared with those with mild or moderate symptoms (21.4% vs. 0% and 7.5%, respectively; p = 0.004). Within 1 year, 85 patients (75.9%) experienced symptom improvement and/or resolution at a median of 3 months. Receipt of immunosuppressive therapy was predictive of improvement or resolution at 1 month (odds ratio 4.22; p = 0.045). One-year physician-assessed cosmesis was excellent or good for 20/35 patients (57.1%) and was not associated with type of treatment or symptom severity. CONCLUSION: Although GM can have a protracted course, the majority of patients in this registry resolved within 1 year, with good cosmetic result. Treatment with immunosuppression appears to be most beneficial, and a symptom-based algorithm may be helpful to guide treatment.
RESUMO
BACKGROUND: After treatment of pregnancy-associated breast cancer (PABC), some women desire future pregnancy. While safety of pregnancy after breast cancer has been demonstrated, the same cannot be said about women with PABC. OBJECTIVE: The aim of this study was to describe the incidence and outcomes of patients with PABC with subsequent pregnancies compared with those without another pregnancy. METHODS: A retrospective chart review identified patients diagnosed with breast cancer during pregnancy or within 5 years postpartum between 2011 and 2023. Patients were then screened for further pregnancy. Clinicopathologic variables, oncologic outcomes, and pregnancy outcomes were recorded. The Chi-square test and t-test were used to compare patients with subsequent pregnancy with those without. Kaplan-Meier method and log-rank test were used to estimate 5-year disease-free survival (DFS). RESULTS: Overall, 75 patients with PABC were identified, 58 of whom had PABC and no further pregnancies (NSP-PABC) and 17 with subsequent pregnancy (SP-PABC). Compared with patients with NSP-PABC, patients with SP-PABC were significantly younger (p = 0.015) and less likely to have prior pregnancies (p < 0.001). Overall median follow-up was 4.3 years. Calculated 5-year DFS rates were 86.2% and 89.0% for the SP-PABC and NSP-PABC groups, respectively (p = 0.76). Calculated 5-year overall survival was 100% and 90.7% for the SP-PABC and NSP-PABC groups, respectively (p = 0.22). Within the SP-PABC group, 14/17 patients had successful deliveries. CONCLUSIONS: This study provides the first descriptions of patients with PABC and subsequent pregnancy. Additional investigation, likely with pooled analysis from multiple institutions, is necessary to determine the oncologic and obstetric safety of pregnancy following PABC.
RESUMO
INTRODUCTION: In academic breast surgery, ultrasound use tends to be limited to radiology departments, thus formal surgical resident training in breast ultrasound is sparse. Building on residents' ultrasound skills in our general surgery training program, we developed a novel curriculum to teach ultrasound-guided breast procedures (UGBPs), including core needle biopsy (CNB) and wire localization (WL). We hypothesized that learning UGBPs on cadavers would be preferred to learning with a breast phantom model using chicken breasts. METHODS: Residents received a 1-h lecture on breast CNB and WL followed by a 1-h hands-on laboratory session. Olives stuffed with red pimentos were used to replicate breast masses and implanted in chicken breasts and the breasts of lightly embalmed and unembalmed female cadavers. All residents practiced UGBPs with a course instructor on both models. Residents completed anonymous prelaboratory and postlaboratory surveys utilizing five-point Likert scales. RESULTS: A total of 35 trainees participated in the didactics; all completed the prelaboratory survey and 28 completed the postlaboratory survey. Participant clinical year ranged from 1 to 6. Residents' confidence in describing and performing CNBs and WLs increased significantly on postlaboratory surveys, controlling for clinical year (P < 0.001). Eighty-point seven percent preferred learning UGBPs on cadavers over phantoms most commonly citing that the cadaver was more realistic. CONCLUSIONS: Following a novel 2-h UGBP training curriculum using phantom and cadaveric models, resident confidence in describing and performing UGBPs significantly improved. Most favored the cadaveric model and reported that the course prepared them for real-life procedures.
RESUMO
INTRODUCTION: The opioid epidemic in the United States is a public health crisis. Breast surgeons are obligated to provide good pain control for their patients after surgery but also must minimize administration of narcotics to prevent a surgical episode of care from becoming a patient's gateway into opioid dependence. METHODS: A survey to ascertain pain management practice patterns after breast surgery was performed. A review of currently available literature that was specific to breast surgery was performed to create recommendations regarding pain management strategies. RESULTS: A total of 609 surgeons completed the survey and demonstrated significant variations in pain management practices, specifically within regards to utilization of regional anesthesia (e.g., nerve blocks), and quantity of prescribed narcotics. There is excellent data to guide the use of local and regional anesthesia. There are, however, fewer studies to guide narcotic recommendations; thus, these recommendations were guided by prevailing practice patterns. CONCLUSIONS: Pain management practices after breast surgery have significant variation and represent an opportunity to improve patient safety and quality of care. Multimodality approaches in conjunction with standardized quantities of narcotics are recommended.

BACKGROUND: Recently introduced multigene panel testing including BRCA1 and BRCA2 genes for hereditary cancer risk has raised concerns with the ability to detect all deleterious BRCA1/2 mutations compared to older methods of sequentially testing BRCA1/2 separately. The purpose of this study was to evaluate rates of pathogenic BRCA1/2 mutations and variants of uncertain significance (VUS) between previous restricted algorithms of genetic testing and newer approaches of multigene testing. METHODS: Data was collected retrospectively from 966 patients who underwent genetic testing at one of three sites from a single institution. Test results were compared between patients who underwent BRCA1/2 testing only (limited group, n = 629) to those who underwent multigene testing with 5-43 cancer-related genes (panel group, n = 337). RESULTS: Deleterious BRCA1/2 mutations were identified in 37 patients, with equivalent rates between limited and panel groups (4.0 vs. 3.6%, respectively, p = 0.86). Thirty-nine patients had a BRCA1/2 VUS, with similar rates between limited and panel groups (4.5 vs. 3.3%, respectively, p = 0.49). On multivariate analysis, there was no difference in detection of either BRCA1/2 mutations or VUS between both groups. Of patients undergoing panel testing, an additional 3.9 % (n = 13) had non-BRCA pathogenic mutations and 13.4% (n = 45) had non-BRCA VUSs. Mutations in PALB2, CHEK2, and ATM were the most common non-BRCA mutations identified. CONCLUSIONS: Multigene panel testing detects pathogenic BRCA1/2 mutations at equivalent rates as limited testing and increases the diagnostic yield. Panel testing increases the VUS rate, mainly as a result of non-BRCA genes. Patients at risk for hereditary breast cancer can safely benefit from up-front, more efficient, multigene panel testing.

INTRODUCTION: Testosterone replacement therapy (TRT) can improve quality of life for men with hypogonadism. However, it is generally avoided in patients with a history of prostate cancer or breast cancer as there is uncertainty about risks. This case illustrates an example of synchronous metastatic prostate cancer and male breast cancer following TRT. PRESENTATION OF CASE: A 72-year-old man with previously treated intermediate-risk prostate adenocarcinoma experienced a gradual rise in prostate-specific antigen (PSA) while self-administering testosterone replacement. He was later found to have recurrent metastatic prostate cancer and prior to initiating androgen deprivation therapy (ADT), he was also diagnosed with male breast cancer. His treatment has consisted of continued ADT for metastatic castration-sensitive prostate cancer (mCSPC) as well as surgical resection of his breast cancer. DISCUSSION: ADT plays a role in treatment of male breast cancer and prostate cancer. TRT remains relatively contraindicated in patients with a history of these malignancies, but the evidence supporting this recommendation is somewhat limited. CONCLUSION: This case highlights the potential risk for synchronous recurrent prostate and new male breast cancer following TRT. Further studies are needed to better elucidate the increased risks of these malignancies with TRT.
RESUMO
BACKGROUND: There are few data on the long-term outcome of patients with microinvasive (T1mi) breast cancer. Moreover, predictors of lymph node involvement and the impact of multifocal microinvasion are not well understood. METHODS: Patients with T1mi cancer, defined as tumors ≤1 mm, surgically managed at our institute and who underwent axillary lymph node evaluation were identified. Specimen slides were independently reviewed. Multivariate analysis was used to identify factors predictive of lymph node involvement. RESULTS: Forty-five patients with T1mi cancer were identified. Median patient age was 52 years, and median size of in situ disease was 4 cm. Nine tumors (20.0 %) had more than one focus of microinvasion. Lymph nodes metastasis were identified in 9 patients: 1 macrometastasis (2.2 %), 4 micrometastases (8.9 %), and 4 isolated tumor cells (8.9 %). Seven of 9 patients with lymph node involvement underwent adjuvant chemotherapy. Estrogen receptor-negative invasive disease was a significant predictor of lymph node metastasis by multivariable analysis (p < 0.02). There was also a trend toward lymph node involvement in patients with multifocal microinvasion compared to unifocal disease (33.3 vs. 16.7 %, respectively). At a median follow-up of 83 months, 3 patients (6.3 %) had disease recurrence (1 local, 1 distant, 1 local and distant). All patients with recurrence initially had tumor-free lymph nodes and only one focus of microinvasion. CONCLUSIONS: Microinvasive breast cancer clearly has the ability to metastasize and recur, but in this series, only 2 % of patients with nodal macrometastasis. Only two patients experienced local recurrence, neither of whom had lymph node metastasis. The importance of identifying nodal micrometastasis in T1mi disease needs to be further explored.

BACKGROUND: In a previous study of the relationship between breast density and primary tumor features, we observed a higher mastectomy rate in patients with extremely dense breasts. Here we examine possible reasons for this finding. METHODS: Data were obtained from a prospectively maintained database of 1,056 invasive breast cancer patients from January 2005 to June 2007. Mammographic density was assigned by Breast Imaging-Reporting and Data System (BI-RADS) classification. Initial and final surgical procedures, and patient and tumor variables were recorded. RESULTS: Breast-conserving surgery (BCS) was attempted in 758 patients (72 %), 385 (51 %) of whom had preoperative magnetic resonance imaging (MRI). Initial BCS was less common among patients with the highest (BI-RADS 4) breast density compared to patients with less-dense breasts (52 vs. 74 %; p < 0.0001), but MRI use was more common (65 vs. 33 %; p < 0.0001). Adjusting for clinical and pathologic variables, patients with the highest breast density had 1.94-times (95 % confidence interval 1.44-2.62; p < 0.0001) the odds of initial mastectomy compared to patients with less-dense breasts. After initial BCS, 387 patients (51 %) had positive shaved margins, 96 (25 %) of whom converted to mastectomy. MRI did not correlate with the rate of positive margins overall or among those with dense breasts. Adjusting for clinical and pathologic variables, density did not predict margin status or conversion to mastectomy. In a multivariate model, age, histologic grade, extensive intraductal component, and multicentricity/multifocality were independently associated with conversion to mastectomy. CONCLUSIONS: Density alone seems to influence the decision to proceed with initial mastectomy. When BCS was attempted, breast density was not associated with positive margins or conversion to mastectomy. A benefit of MRI in decreasing positive margins was not observed. These data do not support the use of breast density as a selection criterion for BCS.

Kimura disease is a rare inflammatory lesion of the head and neck region, usually seen in young Asian men. Patients usually present with a painless mass involving a major salivary gland with lymphadenopathy. Current studies suggest an immunologic mechanism for the pathogenesis of this disease entity. Histopathologically, this tumor is composed of vascular proliferation and lymphoid infiltrate rich in eosinophils. The immunohistochemical findings are usually nonspecific but might help in eliminating malignancies. The role of fine needle aspiration (FNA) and biopsy procedure appears to be limited in making the histologic diagnosis of Kimura disease. The natural history of the disease, however, appears to be indolent, without any malignant transformation reported, although recurrence can be frequent. Here, we describe 2 cases of Kimura disease with differing presentations, diagnostic difficulties, and their clinical management. The difficulties encountered in establishing an accurate preoperative diagnosis and the complexity of surgical management highlight the need for an index of suspicion for this clinical entity while mandating appropriate surgical management to minimize operative morbidity and reduce the risk of recurrence.

Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks. We report a case series of four young women-ages from 21 to 39-with multifocal invasive breast cancer that raises the concern of a possible association with nonionizing radiation of electromagnetic field exposures from cellular phones. All patients regularly carried their smartphones directly against their breasts in their brassieres for up to 10 hours a day, for several years, and developed tumors in areas of their breasts immediately underlying the phones. All patients had no family history of breast cancer, tested negative for BRCA1 and BRCA2, and had no other known breast cancer risks. Their breast imaging is reviewed, showing clustering of multiple tumor foci in the breast directly under the area of phone contact. Pathology of all four cases shows striking similarity; all tumors are hormone-positive, low-intermediate grade, having an extensive intraductal component, and all tumors have near identical morphology. These cases raise awareness to the lack of safety data of prolonged direct contact with cellular phones.
RESUMO
The standard operation for patients with multicentric breast cancer is total mastectomy. The safety of breast-conserving surgery (BCS) for these patients is unknown but interest in BCS has recently resurfaced as a result of the detection of occult second malignancies by breast magnetic resonance imaging (MRI). We report a small number of patients who chose to undergo "double lumpectomies," defined as two separate segmental mastectomies for primary cancers in different quadrants of the same breast. Patients with multicentric breast cancer surgically managed with double lumpectomies at our institute were identified retrospectively. Clinicopathologic features are described and outcomes reported. Seven patients underwent double lumpectomies for multicentric carcinoma. Median age was 69 years (range, 61 to 80 years). In five patients, MRI identified ipsilateral second malignancies. All patients had two foci of invasive carcinoma, all tumors expressed estrogen receptor, and none showed HER-2 overexpression. Tumor sizes ranged from 0.7 to 2.9 cm. Six patients had histologically distinct tumors in the same breast: five had one invasive lobular carcinoma (ILC) and one invasive ductal carcinoma (IDC), and one had classic ILC in one quadrant and pleomorphic ILC in another. One patient had two foci of IDC in separate quadrants. All patients had sentinel lymph node biopsies and none had nodal metastasis. Median follow-up was 26 months (range, 18 to 85 months). No patient developed locoregional recurrence. This small series suggests that "double lumpectomy" may be considered for multicentric invasive breast carcinoma in carefully selected patients with favorable tumors who desire breast conservation.

OBJECTIVE To examine the long-term outcome of patients with early breast cancer with hematoxylin-eosin-negative sentinel lymph nodes (SLNs) who did not undergo completion axillary lymph node dissection. DESIGN, SETTING, AND PATIENTS Patients with invasive breast cancer surgically treated between May 1, 1995, and December 31, 2002, with SLN biopsy alone without axillary lymph node dissection who had hematoxylin-eosin-negative SLNs were identified. MAIN OUTCOME MEASURES Patient and tumor characteristics, adjuvant treatment, disease recurrence, and survival were recorded. A multivariable analysis model was used to identify significant variables associated with disease-free survival and overall survival. RESULTS A total of 811 patients were included, with a median follow-up of 103.1 months (range, 12.2-182.8 months). The mean patient age was 57.8 years (range, 26-91 years), the mean tumor size was 1.5 cm (range, 0.1-7.5 cm), and the median number of SLNs obtained was 2 (range, 1-8). Seventy-six patients (9.4%) developed disease recurrence; there were 2 patients (0.2%) with isolated axillary recurrences, 40 (4.9%) with local recurrences, 4 (0.5%) with local and regional recurrences, 22 (2.7%) with distant recurrences, and 8 (1.0%) with both local and distant recurrences. The median time to recurrence was 57.2 months (range, 3.1-163.3 months), with 5-year and 10-year disease-free survival rates of 95.1% and 89.9%, respectively. One hundred one patients (12.5%) died; only 15 (1.8%) had distant metastatic disease at the time of death. Patients were significantly more likely to have disease recurrence if they had high-grade tumors (P = .004). Older age and larger tumor size were significant predictors of worse overall survival on multivariate analysis (P < .001 and P = .01, respectively). CONCLUSIONS This study reports the long-term follow-up of patients with breast cancer and hematoxylin-eosin-negative, tumor-free SLNs, showing a remarkably low axillary recurrence of 0.2% and high disease-free survival. Long-term results of SLN biopsy alone are excellent, and the addition of immunohistochemistry analysis does not contribute to survival.
