- Abstract
Introduction: Triple-negative breast cancer (TNBC) has a prevalence of 12%-24% in the Hispanic population. Previous research has demonstrated that disparities in healthcare access significantly influence patient outcomes. We aimed to compare the clinicopathological characteristics and outcomes of Hispanic females with TNBC living in Latin America (HPLA) to the Hispanic population in the United States (HPUS)., Methods: We evaluated two retrospective cohorts: patients diagnosed with TNBC at the Instituto Nacional de Enfermedades Neoplasicas, Lima, Peru, during 2000-2015, and HPUS patients with TNBC from the Surveillance, Epidemiology, and End Results Program (SEER)., Results: A total of 2007 HPLA and 8457 HPUS patients were included. The HPLA patients were younger and more frequently lived in nonmetropolitan areas. HPLA had higher T and N (p < 0.001) stages. HPLA patients were more likely to present with Stage III disease (51.6% vs. 20.8%), while Stage IV presentations were similar 6.6% vs. 6.8%. HPLA patients with Stages I and II more frequently underwent mastectomy compared to HPUS (56.2 vs. 48.0%). HPLA patients received neoadjuvant chemotherapy (p < 0.001), adjuvant chemotherapy (p < 0.001), and radiotherapy (p < 0.001) more often. While early breast cancer stages had similar overall survival (OS) rates for both populations, HPLA patients had worse 5-year OS rates compared to HPUS patients in Stages III (39.9% vs. 52.3%, p < 0.001) and IV (4.6% vs. 10.7%, p < 0.001)., Conclusions: Hispanic females living in Latin America were more frequently diagnosed with advanced stages of TNBC and more often underwent mastectomy, even in early-stage disease. When analyzing advanced stages, HPLA had worse OS rates compared to HPUS., (© 2025 Wiley Periodicals LLC.)

- Abstract
Background: Obesity has nearly tripled in the last 50 years. During the last decades, oncoplastic breast surgery has become an important choice in the surgical treatment of breast cancer. An association exists between higher body mass index (BMI) and wound complications for major operations, but there is scarce literature on oncoplastic surgery. Hence, our aim was to compare the complication rates among patients who underwent oncoplastic surgery, stratified by BMI., Methods: Patient data were analyzed from the National Surgical Quality Improvement Program database (NSQIP) for oncoplastic breast procedures (2005-2020). Patients were stratified according to World Health Organization obesity classifications. Multivariate logistic regression was performed to assess risk factors for complications (overall, operative, and wound-related)., Results: From a total of 6887 patients who underwent oncoplastic surgery, 4229 patients were nonobese, 1380 had Class 1 obesity (BMI: 30 to <35 kg/m
2 ), 737 Class 2 obesity (BMI: 35 to <40 kg/m2 ), and 541 Class 3 obesity (BMI: ≥ 40 kg/m2 ). Greater operative time was found according to higher BMI (p < 0.001). Multivariate analysis adjusted for baseline characteristics showed that patients with obesity Class 2 (odds ratio [OR] = 1.51, 95% confidence interval [CI]: 1.03-2.23, p = 0.037) and 3 (OR = 1.87, 95% CI 1.24-2.83, p = 0.003) had increased risk of overall and wound complications compared with Nonobese patients. Comparing obese with nonobese patients, there were no differences in rates of deep SSI, organ/space SSI, pneumonia, reintubation, pulmonary embolism, deep vein thrombosis, urinary tract infection, stroke, bleeding, postoperative sepsis, length of stay, and readmission., Conclusions: Oncoplastic surgery is a safe procedure for most patients. However, caution should be exercised when performing oncoplastic surgery for patients with Class 2 or 3 obesity (BMI ≥ 35 kg/m2 ), given there was a higher rate of overall and wound-specific complications, compared with patients who were not obese or had Class 1 obesity., (© 2023 Wiley Periodicals LLC.)- Published

- Abstract
Background: Accuracy of tumor bed (TB) delineation is essential for targeting boost doses or partial breast irradiation. Multiple studies have shown high interobserver variability with standardly used surgical clip markers (CMs). We hypothesize that a radiopaque filament marker (FM) woven along the TB will improve TB delineation consistency., Methods: An FDA-approved FM was intraoperatively used to outline the TB of patients undergoing lumpectomy. Between January 2020 and January 2022, consecutive patients with FM placed after either (1) lumpectomy or (2) lumpectomy with oncoplastic reconstruction were identified and compared with those with CM. Six "experts" (radiation oncologists specializing in breast cancer) across 2 institutions independently defined all TBs. Three metrics (volume variance, dice coefficient, and center of mass [COM] deviation). Two-tailed paired samples t tests were performed to compare FM and CM cohorts., Results: Twenty-eight total patients were evaluated (14 FM and 14 CM). In aggregate, differences in volume between expert contours were 29.7% (SD ± 58.8%) with FM and 55.4% (SD ± 105.9%) with CM ( P < 0.001). The average dice coefficient in patients with FM was 0.54 (SD ± 0.15), and with CM was 0.44 (SD ± 0.22) ( P < 0.001). The average COM deviation was 0.63 cm (SD ± 0.53 cm) for FM and 1.05 cm (SD ± 0.93 cm) for CM; ( P < 0.001). In the subset of patients who underwent lumpectomy with oncoplastic reconstruction, the difference in average volume was 21.8% (SD ± 20.4%) with FM and 52.2% (SD ± 64.5%) with CM ( P <0.001). The average dice coefficient was 0.53 (SD ± 0.12) for FM versus 0.39 (SD ± 0.24) for CM ( P < 0.001). The average COM difference was 0.53 cm (SD ± 0.29 cm) with FM versus 1.25 cm (SD ± 1.08 cm) with CM ( P < 0.001)., Conclusion: FM consistently outperformed CM in the setting of both standard lumpectomy and complex oncoplastic reconstruction. These data suggest the superiority of FM in TB delineation., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
The promising results of the robotic approach for multiple cancer operations has led to interest in the potential of robotic nipple-sparing mastectomy (R-NSM); however, further studies are required to compare the benefits and complications of this approach with those of conventional open nipple-sparing mastectomy (C-NSM). We performed a meta-analysis to compare surgical complications of R-NSM versus C-NSM. We performed a review of literature through June 2022 in PubMed, Scopus, and EMBASE. We included randomized controlled trials (RCTs), cohorts, case-control studies, and case series with > 50 patients comparing the two techniques. Separate meta-analyses were conducted according to study design. From 80 publications, we identified six studies. The sample size ranged from 63 to 311 mastectomies from 63 to 275 patients. The tumor size and disease stage were similar between groups. The positive margin rate was 0-4.6% in the R-NSM arm and 0-2.9% in the C-NSM arm. Four studies reported early recurrence data, which were similar between groups (R-NSM: 0%, C-NSM: 0-8%). The R-NSM group had a lower rate of overall complications compared to the C-NSM group in cohorts/RCTs (RR = 0.68, 95%CI 0.49-0.96). In case-control studies, rate of necrosis was lower with R-NSM. Operative time was significantly longer in the R-NSM group in cohort/RCTs. In early experience with R-NSM, R-NSM had a lower overall complication rate compared to C-NSM in cohorts/RCTs. While these data are promising, our results show variability and heterogeneity limiting definitive conclusions. Additional trials are needed to guide the role of R-NSM and its oncologic outcomes., (© 2023. The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.)

- Abstract
Breast surgery is performed to achieve local control in patients with breast cancer. Visualization of the anatomy with a virtual reality software platform reconstructed from magnetic resonance imaging data improves surgical planning with regards to volume and localization of the tumor, lymph nodes, blood vessels, and surrounding tissue to perform oncoplastic tissue rearrangement. We report the use and advantages of virtual reality added to the magnetic resonance imaging assessment in a 36-year-old woman with breast cancer who underwent nipple sparing mastectomy with tissue expander reconstruction., (© The Author(s) 2023.)

- Abstract
Background: The COVID-19 pandemic altered access to healthcare by decreasing the number of patients able to receive preventative care and cancer screening. We hypothesized that, given these changes in access to care, radiologic screening for breast and lung cancer would be decreased, and patients with these cancers would consequently present at later stages of their disease., Study Design: This is a retrospective cross-sectional study of 2017 to September 2021 UMass Memorial Tumor Registry data for adult breast and lung cancer patients. Changes in stage at presentation of breast and lung cancer during the COVID-19 pandemic were measured, defined as before and during COVID-19., Results: There were no statistically significant changes in the overall stage of presentation before or during the COVID-19 pandemic for either breast or lung cancer patients. Analysis of case presentation and stage during periods of COVID-19 surges that occurred during the time of this study compared with prepandemic data demonstrated a statistically significant decrease in overall presentation of breast cancer patients in the first surge, with no other statistically significant changes in breast cancer presentation. A nonstatistically significant decrease in lung cancer presentation was seen during the initial surge of COVID-19. There was also a statistically significant increase in early-stage presentation of lung cancer during the second and third COVID-19 surges., Conclusions: In the 2 years after the COVID-19 pandemic, we were not able to demonstrate stage migration at presentation of breast and lung cancer patients to later stages despite decreases in overall presentation during the initial 2 years of the COVID pandemic. An increase in early-stage lung cancer during the second and third surges is interesting and could be related to increased chest imaging for COVID pneumonia., (Copyright © 2023 by the American College of Surgeons.
