Lack of Racial Diversity in Surgery and Pathology Textbooks Depicting Diseases of the Breast.

INTRODUCTION: The lack of racial diversity depicted in medical education texts may contribute to an implicit racial bias among clinicians. This bias influences outcomes, as familiarity with the various cutaneous manifestations of disease is essential to making an accurate diagnosis. To better understand the racial disparities in breast surgery, we sought to determine the extent of skin tone representation depicted in images of breast surgery and pathology textbooks. METHODS: Textbooks were screened for color images of conditions with sufficient skin tissue present to assign the Fitzpatrick skin phototype (FSP). Figures were independently assigned an FP score (range: 1-6), and subdivided into "light skin" (FP 1-3) and "dark skin" (FP 4-6). Number of figures in each category and percentage of patients with each skin tone were calculated. RESULTS: 557 figures were included. Among 12 textbooks reviewed, seven textbooks were from the discipline of surgery, while five were pathology-related. Textbook year of publication spanned from 1996 to 2018. Overall, 533 (95.7%) figures depicted patients with light skin color versus 24 (4.3%) with dark skin color. There was no association between FP score and year of textbook publication (P = 0.69). CONCLUSIONS: Patient images in breast textbooks are overwhelmingly of light skin tones, excluding patients with darker skin tones. The dearth of images depicting dark skinned individuals did not improve over time. Inclusion of patients of color in future textbooks may help reduce racial disparities within breast cancer care.

Rapid Adoption of an Interdisciplinary Care Team Model for Surgical Residents Managing Coronavirus Disease-19.

Introduction: Patients infected with SARS-Cov-2, the causative virus behind the coronavirus disease-19 (COVID-19) pandemic, have been increasing rapidly in New York City. New York City has the highest incidence in the United States and fully 45% of all deaths from COVID-19. Our medical center is located within a high-density region of cases in south Brooklyn and, in fact, three of our neighborhood zip codes are in the top seven in New York in incidence. As a result, our center has experienced a dramatic increase in hospitalizations, particularly respiratory distress secondary to COVID-19, which rapidly exceeded the capacity of our internal medicine service. This necessitated the formation of new COVID-19 units throughout the hospital, replacing all former service lines. These units employed management teams composed of residents from many medical and surgical disciplines, including general surgery residents. Methods: Our general surgery residency program established a surgical COVID-19 (SCOVID) management team. Initially, 4 surgical residents (2 senior and 2 junior), 1 attending surgeon, and 1 attending internal medicine physician were allocated to the initial SCOVID team. On day 3 of implementation, to achieve more rapid competence in the complex management of these patients, a senior medicine resident with direct experience in the care of COVID-19 patients was added in an advisory capacity. Results: The addition of an experienced senior medical resident and attending allowed for the quick adoption of uniform management protocols by surgical residents and attendings. Discussion: We describe a protocol for the establishment of COVID-19 management teams staffed with general surgical residents, as well as a strategy for the achievement of rapid increases in competency. The addition of a senior internal medicine resident and attending to our SCOVID team allowed for rapid achievement of competency in the care of COVID-19 patients in our large institution at the epicenter of the COVID-19 pandemic.

Obese Patients Who Receive an Opioid-Sparing Enhanced Recovery After Surgery (ERAS) Protocol are at Increased Risk of Persistent Pain After Breast Surgery.

BACKGROUND: Obese patients are at increased risk of persistent pain and chronic opioid dependence after surgery. We sought to evaluate the impact of an Enhanced Recovery After Surgery (ERAS) protocol in breast surgery patients to determine whether multimodal analgesia was effective for both obese and non-obese patients. METHODS: A prospective cohort of patients undergoing breast surgery who received an opioid-sparing ERAS protocol was compared with patients who did not receive ERAS, including a historical cohort. Pain scores were compared with respect to body mass index (BMI). Obesity was defined as BMI ≥ 30, and moderate to severe pain was defined as 4-10 of a 10-point scale. Postoperative day one and week one pain scores were compared using the Kruskal-Wallis test. RESULTS: A combined contemporary and historical cohort of 1353 patients underwent lumpectomy and mastectomy without reconstruction. The present analysis comprises 622 patients with pain scores who did and did not receive ERAS between 2015 and 2018. The two groups were demographically similar. The day after surgery, those who received ERAS reported lower rates of moderate to severe pain, regardless of BMI (obese: 46.3% vs. 21.8%, p < 0.001; non-obese: 36.3% vs. 19.4%, p = 0.002). One week after surgery, obese patients who received ERAS had higher rates of persistent pain compared with non-obese patients (18.6% vs. 11.1%, p = 0.042). CONCLUSIONS: An opioid-sparing ERAS protocol utilizing multimodal analgesia significantly improved postoperative pain control for obese and non-obese patients. However, it appears that obese patients are still at relatively greater risk for persistent pain after surgery.

Larvae of Musca domestica (common house fly) found intraoperatively in a male breast abscess.

A 62-year-old male with type 2 diabetes mellitus presented to our nationally accredited breast center with bilateral breast masses present for 7 years and new-onset pink nipple discharge for several months. Mammography and ultrasound demonstrated a left 2.7 retroareolar cystic lesion and a right 2.1 cm retroareolar solid lesion. Given the suspicious nature of the bilateral breast discharge, core needle biopsies were performed to rule out underlying malignancy. The biopsies revealed benign results, but the discordance between the biopsy, imaging, and suspicious discharge led to the decision to perform bilateral excisional biopsies. Intraoperatively, a small organism resembling a larva was encountered. The abnormal tissue was sent for histopathological examination, along with the organism, which was identified as the larvae of Musca domestica, or common house fly.

The natural history of untreated estrogen receptor-positive, Her2-negative invasive breast cancer.

BACKGROUND: Using prior mammograms from patients with delays in their breast cancer diagnoses, we sought to describe in-vivo growth kinetics of untreated breast cancer to determine if the time they became clinically apparent can be predicted. METHODS: Patient and tumor characteristics were collected from those who presented with "missed," untreated breast cancer to a breast center in a single institution. Only patients whose biopsied masses revealed estrogen receptor-positive, Her2-negative (ER+/Her2-) invasive cancers were included. Two attending radiologists reviewed images from prior mammograms. Rates of change in volume were calculated in mm3/day, and a logarithmic equation was used to calculate tumor volume doubling time (TVDT). A Spearman's Rho correlation was performed for the continuous variables, and the Mann-Whitney U and Kruskal-Wallis tests were used to compare categorical data. A p value < 0.05 was considered statistically significant. Logistic regression was performed to determine if patient or tumor characteristics were correlated to tumor growth velocity. RESULTS: Of the 36 ER+/Her2- invasive breast cancers included in the analysis, 13 (36%) were at least cT2 (of TNM), 7 (19%) were grade 3, and 7 (19%) were node positive at diagnosis. Grade (p = 0.043) and pathologic invasive tumor size (p = 0.001) were positively correlated to tumor growth velocity. Median TVDT was 385 days (23-1897). Age, nodal positivity, Oncotype Dx® Recurrence Score, time of diagnostic delay, and spheroid-ellipsoid discrepancy (SED) were not related to tumor growth velocity in this sample. CONCLUSION: In this cohort of patients with untreated ER+/Her2- invasive breast cancers, grade and pathologic tumor size were found to be positively correlated to growth velocity. The growth rates in a homogeneous group of tumors varied widely and could not be predicted. One possible explanation for this finding is that other difficult-to-measure biologic factors such as tumor microenvironment may play a greater role in tumor progression than traditional clinicopathologic characteristics.

Mastectomy is no longer an indication for postoperative opioid prescription at discharge.

BACKGROUND: A 10-step protocol employing multimodal analgesia was implemented in patients undergoing mastectomy to decrease the quantity of opioids prescribed at discharge. METHODS: Patients who received the Enhanced Recovery After Surgery (ERAS) protocol were compared to a control group. Inpatient and discharge prescription of opioids were compared using oral morphine equivalents (OMEs), along with postoperative pain scores. RESULTS: Between 2017 and 2018, fifty-seven patients were eligible for inclusion: 20 patients received ERAS and 37 received usual care (UC). The ERAS group received a mean of 2.4 (0-13) inpatient OMEs and the UC group received 13.7 (0-80) (p = 0.002). The ERAS group received 2.0 (0-40) OMEs at discharge and the UC group received 59.8 (0-120) (p < 0.001). Postoperative pain scores were significantly lower in the patients who received the ERAS protocol. CONCLUSIONS: Patients who received the ERAS protocol required less postoperative opioids and reported lower pain scores when compared to a control group.

A Review of Pregnancy-Associated Breast Cancer: Diagnosis, Local and Systemic Treatment, and Prognosis.

The incidence of pregnancy-associated breast cancer (PABC) increases as more women choose to delay childbearing and the population-based incidence of breast cancer rises. Reliably and safely staging PABC is necessary to choose between starting with local or systemic therapy. With regard to local therapy, both lumpectomy and mastectomy can be considered depending on gestational age and the stage at diagnosis. By mirroring nonpregnant treatment regimens as much as possible, chemotherapy may improve long-term oncologic outcomes while allowing for surgical downstaging during pregnancy. Delaying treatment due to misconceptions regarding risk of local and systemic therapy most certainly worsens oncologic outcomes, and most neonatal morbidity is related to gestational age at delivery and not in utero exposures. Pregnancy itself was once considered an independent risk factor for worse outcome, but the prognosis of these patients is not significantly different than nonpregnant counterparts of a similar age.

Leveraging the variable natural history of ductal carcinoma in situ (DCIS) to select optimal therapy.

PURPOSE: Ductal carcinoma in situ (DCIS) is a non-obligate precursor to invasive ductal carcinoma. The authors sought to discuss the evidence suggesting that not all DCIS will progress to invasive disease if left untreated. RESULTS: Four lines of evidence align to suggest that not all of this in-situ disease progresses to invasive cancer: its prevalence on screening mammography, studies of missed diagnoses, incidental findings in autopsy specimens, and large retrospective reviews of those treated with excision alone. CONCLUSION: A clearer understanding of the variable history of DCIS coupled with advances in genomic profiling of the disease holds the promise of reducing widespread over-treatment of this non-invasive cancer. Additionally, identification of higher risk of recurrence subsets may select patients for whom more aggressive treatment may be appropriate.

A pilot study of a breast surgery Enhanced Recovery After Surgery (ERAS) protocol to eliminate narcotic prescription at discharge.

BACKGROUND: The evolving conceptualization of the management of surgical pain was a major contributor to the supply of narcotics that led to the opioid crisis. We designed and implemented a breast surgery-specific Enhanced Recovery After Surgery (ERAS) protocol using opioid-sparing techniques to eliminate narcotic prescription at discharge without sacrificing perioperative pain control. METHODS: A pilot observational study included patients with and without cancer undergoing lumpectomy. The convenience sample consisted of an ERAS group and a control usual care (UC) group who underwent surgery during the same time period. Discharge narcotic prescriptions were compared after converting to oral morphine milligram equivalents (MME's). Postoperative day one and week one pain scores were also compared between the two groups. RESULTS: Ninety ERAS and 67 UC patients were enrolled. Most lumpectomies were wire-localized, and half of the patients in each group had breast cancer. There were more obese patients in the ERAS group. UC lumpectomy patients were discharged with a median of 54.5 MMEs (range 0-120), while the ERAS lumpectomy patients were discharged with none (p < 0.001). Postoperative pain scores were not significantly different between groups, and there were few complications. CONCLUSION: A breast surgery-specific ERAS protocol employing opioid-sparing techniques successfully eliminated postoperative narcotic prescription without sacrificing perioperative pain control or increasing postoperative complications. By promoting the adoption of similar protocols, surgeons can continue to improve patient outcomes while decreasing the quantity of narcotics available for diversion within our patients' communities.

The role of the breast cancer surgeon in personalized cancer care: clinical utility of the 21-gene assay.

BACKGROUND: Breast cancer surgeons represent the first line of defense for many patients battling this disease. They often have the first contact to discuss treatment options with the patient after diagnosis. However, the potential impact of this consultation has evolved with the arrival of commercialized multigene prognostic and predictive tests that continue to reshape the landscape of breast cancer management, including modern surgical practice. METHOD: This review was compiled from peer-reviewed literature indexed in PubMed. CONCLUSIONS: The advent of genomic analysis has advanced the treatment and management of breast cancer toward the goal of personalized care. Therefore, the role of the surgeon now extends beyond extirpation of the tumor and includes an understanding of the biology of the disease as well as an appreciation of this new technology. Breast cancer surgeons should seize this opportunity to provide patients and colleagues with this information in an expeditious manner to optimize clinical outcomes.

Use of text messaging to enhance compliance with the accreditation council for graduate medical education resident duty hour requirements.

PURPOSE: Recently, the Accreditation Council for Graduate Medical Education (ACGME) has developed and enforced a complex set of regulations limiting resident duty hours (RDHs). One potential method to comply with these stringent regulations and better document resident work hours would be to use text message (TM)/short message service (SMS), allowing rapid, inexpensive, and interactive 2-way delivery of information. The purpose of this study was to document the successful implementation of TM to enhance compliance with the ACGME RDH regulations. METHODS: Our TM system uses TSHEETS (TS; Meridian, Ohio), which is an online time- and labor-management service. After our general surgical residents were registered with the system, the documentation of entry into (texting "t start" to a predetermined number) and exit out of (texting "t stop" to the same number) the hospital could easily be accomplished. The goals of this pilot study were to determine (1) the feasibility of implementing a program such as this and (2) if use of such a program was associated with high resident satisfaction and improved compliance. RESULTS: We registered 39 residents with TS. Within 3 days, compliance rose from 76.9% to 96.2%. After implementation of TM reminders, compliance increased to 100%. A time-tracking resident satisfaction survey was distributed after 8 weeks of data collection. Twenty six of 39 (67%) residents participated in the survey, with 25 (96%) being more satisfied with the current application as compared with either of the previous (manual or swipe card) systems, specifically regarding ease of use and overall ACGME RDH compliance. Self-reported resident scores of their ability to be compliant with ACGME RDH before versus after implementation increased from 47% to 75% (p < 0.05). CONCLUSIONS: We were able to implement successfully a novel technique for ACGME RDH documentation and compliance in a general surgery residency program through the use of TM; this approach employed a state-of-the-art time-tracking method that was associated with high levels of resident work-hour compliance and overall satisfaction.

Occult axillary node metastases in breast cancer are prognostically significant: results in 368 node-negative patients with 20-year follow-up.

PURPOSE: In breast cancer, sentinel lymph node (SLN) biopsy allows the routine performance of serial sections and/or immunohistochemical (IHC) staining to detect occult metastases missed by conventional techniques. However, there is no consensus regarding the optimal method for pathologic examination of SLN, or the prognostic significance of SLN micrometastases. PATIENTS AND METHODS: In 368 patients with axillary node-negative invasive breast cancer, treated between 1976 and 1978 by mastectomy, axillary dissection, and no systemic therapy, we reexamined the axillary tissue blocks following our current pathologic protocol for SLN. Occult lymph node metastases were categorized by pattern of staining (immunohistochemically positive or negative [IHC+/-], hematoxylin-eosin staining positive or negative [H & E +/-]), number of positive nodes (0, 1, > 1), number of metastatic cells (0, 1 to 20, 21 to 100, > 100), and largest cluster size ( 2.0 mm [pN1a]). We report 20-year results as overall survival (OS), disease-free survival (DFS), and disease-specific death (DSD). RESULTS: A total of 23% of patients (83 of 368) were converted to node-positive. Of these, 73% were

Analysis of genetic variation in Ashkenazi Jews by high density SNP genotyping.

BACKGROUND: Genetic isolates such as the Ashkenazi Jews (AJ) potentially offer advantages in mapping novel loci in whole genome disease association studies. To analyze patterns of genetic variation in AJ, genotypes of 101 healthy individuals were determined using the Affymetrix EAv3 500 K SNP array and compared to 60 CEPH-derived HapMap (CEU) individuals. 435,632 SNPs overlapped and met annotation criteria in the two groups. RESULTS: A small but significant global difference in allele frequencies between AJ and CEU was demonstrated by a mean FST of 0.009 (P < 0.001); large regions that differed were found on chromosomes 2 and 6. Haplotype blocks inferred from pairwise linkage disequilibrium (LD) statistics (Haploview) as well as by expectation-maximization haplotype phase inference (HAP) showed a greater number of haplotype blocks in AJ compared to CEU by Haploview (50,397 vs. 44,169) or by HAP (59,269 vs. 54,457). Average haplotype blocks were smaller in AJ compared to CEU (e.g., 36.8 kb vs. 40.5 kb HAP). Analysis of global patterns of local LD decay for closely-spaced SNPs in CEU demonstrated more LD, while for SNPs further apart, LD was slightly greater in the AJ. A likelihood ratio approach showed that runs of homozygous SNPs were approximately 20% longer in AJ. A principal components analysis was sufficient to completely resolve the CEU from the AJ. CONCLUSION: LD in the AJ versus was lower than expected by some measures and higher by others. Any putative advantage in whole genome association mapping using the AJ population will be highly dependent on regional LD structure.

Does the benefit of sentinel node frozen section vary between patients with invasive duct, invasive lobular, and favorable histologic subtypes of breast cancer?

BACKGROUND: Although many questions regarding sentinel lymph node (SLN) biopsy in breast cancer have been answered by observational studies and, increasingly, by prospective trials, the role of intraoperative SLN assessment remains a matter of debate. Here we report in detail the results of intraoperative SLN assessment by frozen section (FS), with particular attention to variations in sensitivity and yield by histologic subtype, by tumor size, and by other clinicopathologic parameters. METHODS: Five thousand two hundred ninety-eight consecutive patients with clinical stage T1-3N0 invasive breast carcinoma had SLN biopsy with intraoperative FS at Memorial Sloan Kettering Cancer Center between 1996 and 2004. We report the results of FS by sensitivity (the proportion of all positive SLN detected by FS) and by yield (the proportion of all FS procedures in which the FS was positive). RESULTS: The sensitivity of FS was 61% overall, was higher for invasive duct (ID) than for invasive lobular (IL) cancers (62% vs. 52%; P = 0.006), and was marginally lower for favorable subtypes (46%; P = 0.26). The yield of FS was 21% overall, with no difference between ID and IL cancers (22% vs. 21%; P = 0.49), and with a substantially lower yield for favorable subtypes (3%; P < 0.001). The yield of FS increased with tumor size for ID and IL cancers (P < 0.001), but not for favorable subtypes. For both ID and IL cancers, the sensitivity and yield of FS were significantly higher with younger patient age, increasing tumor size, and lymphovascular invasion. The yield of FS was <10% for all patients with ID or IL tumors < or =1 cm in size who were older than 60 years of age. Among all FS-positive patients, only 45% were identified by the first FS, whereas 91% were cumulatively identified by the first, second, or third FS. CONCLUSIONS: For patients with ID and IL cancers, the overall sensitivity of FS is >50%, but the yield of FS is <10% for individuals > or =60 years of age with T1a/b tumors. Intraoperative FS may not be worthwhile for this low-yield subset, especially for patients with invasive breast cancer of favorable type.

MRI screening in a clinic population with a family history of breast cancer.

BACKGROUND: Breast MRI is increasingly being used in patients at increased risk for breast cancer; however, guidelines for MRI screening are inadequately defined. We describe our experience with MRI screening in a large population of women with a family history of breast cancer. METHODS: We retrospectively reviewed the Memorial Sloan-Kettering breast cancer surveillance program prospective database from April 1999 to July 2006. Patients with a family history of breast cancer and at least 1 year follow-up were identified. All patients were offered biannual clinical breast examination (CBE) and annual mammography (MMG). MRI screening was performed at the discretion of the physician and patient. RESULTS: Family history profiles revealed 1,019 eligible patients; median follow-up was 5.0 years. MRI screening was performed in 374 (37%) patients resulting in a total of 976 MRIs during the study period. Cancer was detected in 9/374 patients (2%) undergoing MRI screening. Seven cancers were detected by MRI only, for a cancer detection rate of 0.7% (7/976) for screening MRI. When stratified by family risk profile, the positive predictive value (PPV) of MRI was higher (13%) in those patients with the strongest family histories and lower (6%) in patients with less significant family histories. CONCLUSIONS: MRI screening can be a useful adjunct to CBE and MMG in patients with high-risk family histories of breast cancer, yet it has low yield in patients with lower-risk family histories. These data suggest that MRI screening should be reserved for those at highest risk.

The predictive value of ductography and magnetic resonance imaging in the management of nipple discharge.

BACKGROUND: Standard evaluation (physical examination, mammography, sonography) often fails to identify an underlying lesion in patients with suspicious nipple discharge. The aim of this study was to determine the predictive value of ductography (DG) and magnetic resonance imaging (MRI) in this setting. METHODS: Using ICD-9 codes, we retrospectively identified 376 patients who presented with suspicious nipple discharge (ND) (1995-2005); 306 patients (68%) had negative standard evaluation. RESULTS: Among 306 patients, 186 (61%) underwent further evaluation with DG (n = 163) and/or MRI (n = 52), 35 (11%) underwent major duct excision alone (MDE), and 85 (28%) were followed clinically. Ultimately, 182/306 (59%) patients underwent surgery and/or biopsy. Overall incidence of malignant or high-risk pathology was 15% (46/306). DG was completed in 139/163 (85%) studies and detected 12 cancers and seven high-risk lesions (HRL), but failed to identify four cancers and 2 HRL (PPV 19%, NPV 63%). MRI detected seven cancers and three HRL, but failed to identify one cancer and one HRL (PPV 56%, NPV 87%). MDE alone (n = 35) detected five cancers and three HRL. Of all patients not having surgery, (142/306, 41%), one (0.01%) presented with an invasive cancer at 102 months (median follow-up, 6.3 months; range, 0-124 months). CONCLUSIONS: An underlying malignancy was identified in 30/306 (10%) patients with ND and negative standard evaluation. Ductography is a poor predictor of underlying pathology and cannot exclude malignancy. MRI's higher predictive values may allow for improved patient selection and treatment planning; however, MRI should not replace MDE as the gold standard to exclude malignancy in patients with ND and negative standard evaluation.

Doctor, what are my chances of having a positive sentinel node? A validated nomogram for risk estimation.

PURPOSE: Lymph node metastasis is a multifactorial event. Several variables have been described as predictors of lymph node metastasis in breast cancer. However, it is difficult to apply these data-usually expressed as odds ratios-to calculate the probability of sentinel lymph node (SLN) metastasis for a specific patient. We developed a user-friendly prediction model (nomogram) based on a large data set to assist in predicting the presence of SLN metastasis. PATIENTS AND METHODS: Clinical and pathologic features of 3,786 sequential SLN biopsy procedures were assessed with multivariable logistic regression to predict the presence of SLN metastasis in breast cancer. The model was subsequently applied to 1,545 sequential SLN biopsies. A nomogram was created from the logistic regression model. A computerized version of the nomogram was developed and is available on the Memorial Sloan-Kettering Cancer Center (New York, NY) Web site. RESULTS: Age, tumor size, tumor type, lymphovascular invasion, tumor location, multifocality, and estrogen and progesterone receptors were associated with SLN metastasis in multivariate analysis. The nomogram was accurate and discriminating, with an area under the receiver operating characteristic curve of 0.754 when applied to the validation group. CONCLUSION: Newly diagnosed breast cancer patients are increasingly interested in information about their disease. This nomogram is a useful tool that helps physicians and patients to accurately predict the likelihood of SLN metastasis.
