The Landmark Series-Ductal Carcinoma in Situ: The Evolution of Treatment.

The evolution of ductal carcinoma in situ (DCIS) management has been driven by a parallel evolution in our understanding of its natural history. Early trials established the benefit of adjuvant therapies in all patients with DCIS. In contrast, subsequent studies have stratified patients to determine their eligibility for progressively less invasive and less intensive therapies. Large, randomized trials and meta-analyses have supported this shift away from treating DCIS as an homogenous disease treated with similar intensity to invasive breast cancer. This review describes the landmark studies on which current DCIS management is based.

Contralateral Prophylactic Mastectomy Decision-Making: The Partners' Perspective.

BACKGROUND: The rate of contralateral prophylactic mastectomy (CPM) continues to rise despite no improvement in survival, an increased risk of surgical complications, and negative effects on quality of life. This study explored the experiences of the partners of women who undergo CPM. METHODS: This study was part of an investigation into the factors motivating women with early-stage unilateral breast cancer and low genetic risk to opt for contralateral prophylactic mastectomy (CPM). Participating women were asked for permission to invite their partners to take part in interviews. In-depth interviews with partners were conducted using a semi-structured topic guide. A thematic analysis of the data was performed RESULTS: Of 35 partners, all men, 15 agreed to be interviewed. Most perceived their role to be strong and logical. Some hoped their wives would choose a bilateral mastectomy. All felt strongly that the final decision was up to their partners. The partners often framed the decision for CPM as one of life or death. Thus, any aesthetic effects were unimportant by comparison. The male partners had difficulty grasping the physical and emotional changes inherent in mastectomy, which made communicating about sexuality and intimacy very challenging for the couples. In the early recovery period, some noted the stress of managing home life. CONCLUSIONS: The experiences of the male partners provide insight into how couples navigate complex treatment decision-making, both together and separately. There may be a benefit to including partners in pre- and post-surgical counseling to mitigate miscommunication regarding the expected oncologic and emotional outcomes related to CPM.

Racial-ethnic variations in phyllodes tumors among a multicenter United States cohort.

BACKGROUND AND OBJECTIVES: Previous studies have identified racial-ethnic differences in the diagnostic patterns and recurrence outcomes of women with phyllodes tumors (PT). However, these studies are generally limited in size and generalizability. We therefore sought to explore racial-ethnic differences in age, tumor size, subtype, and recurrence in a large US cohort of women with PT. METHODS: We performed an 11-institution retrospective review of women with PT from 2007 to 2017. Differences in age at diagnosis, tumor size and subtype, and recurrence-free survival according to race-ethnicity. RESULTS: Women of non-White race or Hispanic ethnicity were younger at the time of diagnosis with phyllodes tumor. Non-Hispanic Other women had a larger proportion of malignant PT. There were no differences in recurrence-free survival in our cohort. CONCLUSIONS: Differences in age, tumor size, and subtype were small. Therefore, the workup of young women with breast masses and the treatment of women with PT should not differ according to race-ethnicity. These conclusions are supported by our finding that there were no differences in recurrence-free survival.

Contralateral Axillary Nodal Metastases: Stage IV Disease or a Manifestation of Progressive Locally Advanced Breast Cancer?

BACKGROUND: Contralateral axillary nodal metastases (CAM) is classified as stage IV disease, although many centers treat CAM with curative intent. We hypothesized that patients with CAM, treated with multimodality therapy, would have improved overall survival (OS) versus patients with distant metastatic disease (M1) and similar OS to those with locally advanced breast cancer (LABC). METHODS: Using the NCDB (2004-2016), we categorized adult patients with node-positive breast cancer into three study groups: LABC, CAM, and M1. Kaplan-Meier curves were used to visualize the unadjusted OS. Cox proportional hazards models were used to estimate the association of study group with OS. RESULTS: A total of 94,487 patients were identified: 122 with CAM, 12,325 with LABC, and 82,040 with M1 (median follow-up 63.6 months). LABC and CAM patients had similar histology and rates of chemotherapy and endocrine therapy receipt. However, the CAM group had significantly larger tumors, more estrogen-receptor expression, higher T-stage, and more mastectomies than the LABC group. Compared with M1 patients, CAM patients were more likely to have grade 3 and cT4 tumors. Patients with CAM and LABC had similar 5-year unadjusted OS and significantly improved OS vs M1 patients. After adjustment, LABC and CAM patients continued to have similar OS and better OS vs M1 patients. CONCLUSIONS: CAM patients who receive multi-modal therapy with curative intent may have OS more comparable to LABC patients than M1 patients. Out data support a reevaluation of whether CAM should remain classified as M1, as N3 may better reflect disease prognosis and treatment goals.

Routine postprocedure ultrasound increases rate of detection of femoral arterial thrombosis in infants after cardiac catheterization.

OBJECTIVES: To examine the effect of implementing postcatheterization ultrasound (US) on femoral arterial thrombosis detection rates and factors associated with thrombosis in infants. BACKGROUND: Although femoral arterial thrombosis is an uncommon complication of cardiac catheterization, it can cause limb threatening complications. Previous studies assessing the utility of postprocedure US to detect thrombosis in infants have utilized US as an adjunct to standard clinical detection methods, are small scale, or include small cohorts of infants within older populations. METHODS: We reviewed institutional records of patients 0-12 months undergoing catheterization from 2007 to 2016. Demographics and procedural data were compared between the thrombosis and non-thrombosis group. Pre- and post-US groups were compared for detected thrombosis rate. Using univariate and multivariable analyses, we identified factors associated with thrombosis. RESULTS: In total, 270 patients underwent 509 catheterizations, with 40 (7.9%) documented thromboses. The rate of thrombus detection in patients younger than 6 months increased from 8.3% to 23.4% (P = 0.006) after implementing routine US. On multivariable analysis, lower weight (P < 0.001), larger arterial sheath size (P < 0.001), and longer procedure duration (P = 0.003) were independently associated with higher odds of thrombosis. CONCLUSIONS: Higher rates of femoral arterial thrombosis detection were observed since implementing an US screening program. Further studies are needed to evaluate age-related changes in hemostasis in this population and how advanced screening methods and anticoagulation protocols may help improve short-term and long-term sequelae of femoral arterial thrombosis.

Revisiting Medical Student Expectations on the Surgery Clerkship.

OBJECTIVE: Medical students frequently report ambiguity of expectations in their feedback of the surgery clerkship. Herein, we aimed to gauge general surgery resident and attending expectations of students on their clerkship. DESIGN: Residents and attending surgeons were surveyed on medical student expectations for rounding and floor duties, the operating room, clinic, and professionalism. RESULTS: There were slight differences in expectations between residents and attendings, which were then utilized to facilitate a discussion to create consensus expectations for students. Early outcomes demonstrate improved understanding of expectations by medical students. CONCLUSION: Identifying differences in resident and attending expectations of medical students on their surgery clerkship can help improve the alignment of such expectations. We hope that longterm, this intervention can facilitate a better learning environment for medical students on their surgery clerkship.
