Multidisciplinary Breast Cancer Clinic: A Novel Approach to Decrease Time to Intervention.

Multidisciplinary clinics (MDCs) were created at high-volume surgical oncology centers to optimize breast cancer care, in which patients are seen by multiple subspecialists at one visit. We aim to evaluate our experience with this novel approach. We examined 492 patients with newly diagnosed invasive breast cancer from January 1, 2020, to September 1, 2022. Patients seen at our MDC had a decreased time to intervention across all measured intervals: 3 days faster (10 vs 13 days) from biopsy to clinic visit [t Sat 2.09 > t critical two tail 1.99], 5 days faster (23 vs 28 days) from diagnosis to initiation of neoadjuvant chemotherapy [t Sat 5.12 > t critical two tail 2.019], and 21 days faster (24 vs 45 days) from surgery clinic visit to operation [t Sat 5.12 > t critical two tail 2.019]. Although early in our experience, we have initiated a strategy for improved breast cancer care.

Institutional Analysis of Metaplastic Breast Cancer.

Triple-negative breast cancer (TNBC) is typically managed with neoadjuvant chemotherapy (NAC). Metaplastic breast cancer (MBC), a subtype of TNBC, demonstrates different histologic characteristics and less responsiveness to NAC. We performed this study to achieve a better understanding of MBC, including the impact of neoadjuvant chemotherapy. We identified patients diagnosed with MBC from January 2012 to July 1, 2022. A control group of TNBC breast cancer patients from 2020 who did not meet the criteria for MBC was identified. Demographic data, tumor and nodal characteristics, management strategies employed, response to systemic chemotherapy, and treatment outcomes were recorded and compared between groups. A total of 22 patients were included in the MBC group and demonstrated a 20% response to NAC compared to an 85% response rate in the 42 patients in the TNBC group (P = .003). Five patients have recurred (23%) in the MBC group compared to none in the TNBC group (P = .013).

The Surgeon's Risk of SARS-CoV-2 Infection During the Initial Peak of the COVID-19 Pandemic in New Orleans.

Surgeons who care for patients with active SARS-CoV-2 infection represent a unique population of health care providers whose risk of infection has not been elucidated. The objective of this study was to examine SARS-CoV-2 seroprevalence among surgeons who cared for patients with active SARS-CoV-2 infection compared to other employees within our health care system and also the general public of New Orleans. 105 surgeons at our facilities provided direct surgical care to patients with active SARS-CoV-2 infection and underwent voluntary antibody testing. 2/105 (1.9% CI .2%-6.7%) tested positive for SARS-CoV-2 antibodies. 13 343 hospital employees underwent antibody testing and 1066/13 343 (8.0% CI 7.5%-8.5%) tested positive (1.9% vs. 8.0%; P = .03). We saw a significantly lower SARS-CoV-2 seroprevalence among surgeons who directly cared for infected patients versus other hospital employees. When compared to community seroprevalence (6.9% CI 6.0%-8.0%), seroprevalence among our surgeons is also significantly lower (1.9% vs. 6.9%; P = .04).

Surgical Management of Heterotaxy Syndrome: Current Challenges and Opportunities.

INTRODUCTION: Heterotaxy syndrome presents a unique challenge in surgical management, even in the current era. We hypothesized that certain anatomic subsets merit novel strategies. METHODS: We analyzed morphologic details, surgeries, comorbidities, subsequent admissions, and survival using Kaplan-Meier methods and multivariable risk models from a single-institution experience of 103 consecutive patients with heterotaxy who underwent cardiac surgery between January 1, 1990, and May 31, 2016. RESULTS: Of the 103 patients (50 males and 53 females), 31 had left atrial isomerism, 64 had right atrial isomerism (RAI), and 8 patients' isomerism was indeterminate (IND), with first cardiac operation at a mean 1.0 year (standard deviation ±3.0 years) of age. Kaplan-Meier overall survival estimate was 83.1% at six months, 77.8% at one year, 65.9% at five years, and 52.1% at ten years. Survival was particularly low among RAI following repair of total anomalous pulmonary venous connection (TAPVC) at first operation, with one- and five-year survival of 57% and 46%, respectively. By multivariable analysis, the only risk factor for death during the early phase (hazard model) was repair of TAPVC at the first cardiac operation (hazard ratio [HR]: 4.4, P = .01), and risk factors during the longer term constant phase were atrioventricular valve (AVV) regurgitation (HR: 4.2, P < .01), male gender (HR: 3.7, P < .01), and two-ventricle repair (HR: 3.0, P = .02). Patients with heterotaxy undergoing the Fontan procedure had excellent subsequent survival (85% at ten years). CONCLUSIONS: This analysis of over 100 patients with heterotaxy identified TAPVC requiring initial repair as the major risk factor for early death and important AVV regurgitation as the major risk factor in the longer term. Survival with RAI and early repair of TAPVC were poor, with one-year mortality exceeding 40%. Patients with single ventricle completing the Fontan operation enjoyed outstanding ten-year survival (85%). Initial management of RAI requiring early repair of TAPVC remains challenging. For this high-risk subset, alternative strategies such as early referral for cardiac transplantation evaluation warrant consideration.
