The development of research in genetic and biochemical fields has made it possible to investigate certain metabolic aspects of the microenvironment of chronic skin lesions, including altered cell signalling, highlighting its importance in determining the blockage of repair processes. The purpose of this prospective observational study is to evaluate the efficacy of a medical device consisting of a polyester scaffold enriched with an oleic matrix with controlled release of ROS in the management of LABC skin lesions. During the period from October 2018 to March 2020, 20 patients with locally advanced breast cancer were enrolled and ten were treated with the devices abovementioned. After 30 days of treatment all patients treated reported a general improvement in local conditions with reduction in ulceration area, exudate and odour. The results suggest that the application of these devices even in particular conditions (healthy and neoplastic tissue) does not lead to the onset of negative effects due to the release of ROS, though their role in tissue repair requires further study to fully understand their potential and increase the fields of application of the device by exploiting its modulation capabilities.

The Brazilian Society of Oncological Surgery organized a group of oncological surgeons to discuss surgical aspects associated with locally advanced breast carcinoma. This article reviews the indications, the different surgeries (especially those associated with thoracoabdominal or myocutaneous flaps), and associated complications. It discusses special conditions such as invasion of the chest wall and interscapular thoracic disarticulation. It makes recommendations based on the literature regarding clinical findings, tumor conditions, response to neoadjuvant therapy, choice of flaps in surgery, and tumor biology.

Abstract Background Postmastectomy radiation therapy (PMRT) is an important component in the treatment of locally advanced breast cancer. Optimal timing of therapy in relation to autologous breast reconstruction (ABR) remains clinically debated. Herein, we comparatively analyze short- and long-term outcomes between immediate ABR (I-ABR) and delayed-immediate ABR (DI-ABR) in the setting of PMRT. Methods Adult patients undergoing ABR with PMRT were separated into cohorts based on reconstructive timeline: I-ABR or DI-ABR. The groups were propensity matched 1:1 by age, body mass index, and comorbidities. Surgical site events and long-term clinical outcomes (readmissions, reoperations, and revision procedures) were collected. Univariate analyses were completed using Pearson's chi-squared tests and Fisher's exact tests, and statistical significance was set at p < 0.05. Results One hundred and thirty-two flaps (66 in each cohort) were identified for inclusion. Patients with I-ABR were more likely to experience fat necrosis (p = 0.034) and skin necrosis (p < 0.001), require additional office visits (p < 0.001) and outpatient surgeries (p = 0.015) to manage complications, and undergo revision surgery after reconstruction (p < 0.001). DI-ABR patients, however, had a 42.4% incidence of complications following tissue expander placement prior to reconstruction, with 16.7% of patients requiring reoperation during this time. Only one patient (I-ABR) experienced flap loss due to a vascular complication. Conclusion The complications encountered in both of these groups were not prohibitive to offering either treatment. Patients should be made aware of the specific and unique risks of these reconstruction timelines and involved throughout the entire decision-making process. Plastic surgeons should continue to strive to elucidate innovative approaches that facilitate enhanced quality of life without compromising oncologic therapy.

The main goal of neoadjuvant chemotherapy (NACT) in aggressive breast cancer (BC) subtypes (triple-negative, HER2-positive) is to achieve complete pathological response (pCR), since it is associated with a significant decrease in the likelihood of recurrence and death. Currently, the standard approach for HER2+ BC stage II–III is NACT with the inclusion of a double anti-HER2 blockade, since this significantly increases the frequency of pCR. To date, it remains unclear whether the intensification of modern anthracycline-taxane-containing regimens of NACT affects the incidence of pCR in different BC subtypes, including HER2-positive, provided that a double anti-HER2 blockade is used.The aim of our prospective observational study from daily clinical practice was to assess the efficacy (according to the RCB system and the frequency of pCR) and tolerability of dose-dense NACT in stage II–III HER2-positive BC.Materials and methods. The study included 86 patients, mean age 45 years (26–74 years), in 96.5% of cases, the tumor was represented morphologically by invasive cancer of a nonspecific type, in 53.5% of the tumors had a positive luminal B HER2 phenotype, in 46.5% – non-luminal HER2+. The majority of patients (67.4%) had locally advanced inoperable breast cancer; in 80.2% of cases, metastatic lesions of regional lymph nodes were determined. NACT included anthracyclines and taxanes: four cycles of AC in a dose-dense regimen (once every 2 weeks), then four cycles of docetaxel 75 mg/m2 once every 3 weeks + trastuzumab + pertuzumab.Results. The frequency of pCR = RCB0 in the entire group was 54.7% (47/86), in locally advanced breast cancer – 55.9%, in operable breast cancer – 51.9%. In the luminal HER2+ subtype, the frequency of pCR was lower than in the non-luminal HER2+ subtype – 43.5% vs 67.5%, however, the differences were statistically insignificant (p = 0.09). The frequency of RCB0–I in ER+ HER2+ subtype was 60.9%, as in ER-HER2+ – 80%. Conclusions. In our study, for the first time, the efficacy of dose-dense NACT in HER2+ breast cancer was assessed; it was shown that the frequency of pCR and RCB0–I correspond to those in standard anthracycline-taxane-containing regimens. In the context of the use of double anti-HER2 blockade, the anthracycline stage, most likely, does not need to be escalated, since this does not lead to an increase in the frequency of complete pathomorphological regressions.
