Oncoplastic Breast Surgery versus Conservative Mastectomy in the Management of Large Ductal Carcinoma In Situ (DCIS): Surgical, Oncological, and Patient-Reported Outcomes

Oncoplastic level II breast-conserving surgery (OPS2) allows for wider excisions than standard breast-conserving surgery, but the literature on this technique in the treatment of DCIS is scarce. This study compares OPS2 to conservative mastectomy (CM) in patients undergoing surgery for large DCIS. The clinical, radiological, surgical, and post-operative data of 147 patients who underwent either CM or OPS2 for large DCIS between 2007 and 2021 were retrospectively reviewed. The surgical, oncological, and patient-reported outcomes (PRO) were analyzed and compared between the two groups. The surgical outcomes were similar, in terms of margin involvement (p = 0.211), complication rate (p = 0.827), and re-excision rate (p = 1). The rate of additional surgery for cosmetic optimization was significantly lower in the OPS2 group: only 1 (1.8%) patient required surgical adjustments versus 24 (26.4%) patients in the CM group (p < 0.001). The mean hospital stay was lower in the OPS2 group (p < 0.001). The oncological outcomes did not differ between the two groups (p = 0.662). The PRO analysis showed better outcomes in the OPS2 group, which achieved statistical significance in the sexual well-being module (p = 0.015). Skin sensitivity loss was also significantly lower in the OPS2 group (p < 0.001). When feasible, OPS2 should be considered in the treatment of large DCIS, as it is safe and shows high levels of patient satisfaction

Sentinel node biopsy after neoadjuvant chemotherapy for breast cancer: Preliminary experience with clinically node negative patients after systemic treatment

Sentinel lymph node biopsy (SLNB) following neoadjuvant treatment (NACT) has been questioned by many studies that reported heterogeneous identification (IR) and false negative rates (FNR). As a result, some patients receive axillary lymph node dissection (ALND) regardless of response to NACT, leading to a potential overtreatment. To better assess reliability and clinical significance of SLNB status on ycN0 patients, we retrospectively analyzed oncological outcomes of 399 patients treated between January 2016 and December 2019 that were either cN0-ycN0 (219 pa-tients) or cN1/2-ycN0 (180 patients). The Endpoints of our study were to assess, furthermore than IR: oncological outcomes as Overall Survival (OS); Distant Disease Free Survival (DDFS); and Regional Disease Free Survival (RDFS) according to SLNB status. SLN identification rate was 96.8% (98.2% in patients cN0-ycN0 and 95.2% in patients cN+-ycN0). A median number of three lymph nodes were identified and removed. Among cN0-ycN0 patients, 149 (68%) were confirmed ypN0(sn), whereas regarding cN1/2-ycN0 cases 86 (47.8%) confirmed an effective downstaging to ypN0. Three year OS, DDFS and RDFS were significantly related to SLNB positivity. Our data seemed to confirm SLNB feasibility following NACT in ycN0 patients, furthermore reinforcing its predictive role in a short observation timing

Prepectoral vs. Submuscular Immediate Breast Reconstruction in Patients Undergoing Mastectomy after Neoadjuvant Chemotherapy: Our Early Experience

Background: Conservative mastectomy with immediate prosthetic breast reconstruction (IPBR) is an oncologically accepted technique that offers improved esthetic results and patient quality of life. Traditionally, implants have been placed in a submuscular (SM) plane beneath the pectoralis major muscle (PMM). Recently, prepectoral (PP) placement of the prosthesis has been increasingly used in order to avoid morbidities related to manipulation of the PMM. The aim of this study was to compare outcomes of SM vs. PP IPBR after conservative mastectomy in patients with histologically proven breast cancer treated with neoadjuvant chemotherapy (NAC). Methods: In this retrospective observational study, we analyzed two cohorts of patients that underwent mastectomy with IPBR after NAC in our institution from January 2018 to December 2021. Conservative mastectomy was performed in 146 of the 400 patients that underwent NAC during the study period. Patients were divided into two groups based on the positioning of implants: 56 SM versus 90 PP. Results: The two cohorts were similar for age (mean age 42 and 44 years in the SM and PP group respectively) and follow-up (33 and 20 months, respectively). Mean operative time was 56 min shorter in the PP group (300 and 244 min in the SM and PP group). No significant differences were observed in overall major complication rates. Implant loss was observed in 1.78% of patients (1/56) in the SM group and 1.11% of patients (1/90) in PP group. No differences were observed between the two groups in local or regional recurrence. Conclusions: Our preliminary experience, which represents one of the largest series of patients undergoing PP-IPBR after NAC at a single institution documented in the literature, seems to confirm that PP-IPBR after NAC is a safe, reliable and effective alternative to traditional SM-IPBR with excellent esthetic and oncological outcomes; it is easy to perform, reduces operative time and minimizes complications related to manipulation of PPM. However, this promising results need to be confirmed in prospective trials with longer follow-up

Image-guided localization techniques for surgical excision of non-palpable breast lesions: An overview of current literature and our experience with preoperative skin tattoo

Breast conserving surgery has become the standard of care and is more commonly performed than mastectomy for early stage breast cancer, with recent studies showing equivalent survival and lower morbidity. Accurate preoperative lesion localization is mandatory to obtain adequate oncological and cosmetic results. Image guidance assures the precision requested for this purpose. This review provides a summary of all techniques currently available, ranging from the classic wire positioning to the newer magnetic seed localization. We describe the procedures and equipment necessary for each method, outlining the advantages and disadvantages, with a focus on the cost-effective preoperative skin tattoo technique performed at our centre. Breast surgeons and radiologists have to consider ongoing technological developments in order to assess the best localization method for each individual patient and clinical setting

Level II Oncoplastic Surgery as an Alternative Option to Mastectomy with Immediate Breast Reconstruction in the Neoadjuvant Setting: A Multidisciplinary Single Center Experience

Oncoplastic surgery level II techniques (OPSII) are used in patients with operable breast cancer. There is no evidence regarding their safety and efficacy after neoadjuvant chemotherapy (NAC). The aim of this study was to compare the oncological and aesthetic outcomes of this technique compared with those observed in mastectomy with immediate breast reconstruction (MIBR), in post-NAC patients undergoing surgery between January 2016 and March 2021. Local disease-free survival (L-DFS), regional disease-free survival (R-DFS), distant disease-free survival (D-DFS), and overall survival (OS) were compared; the aesthetic results and quality of life (QoL) were evaluated using BREAST-Q. A total of 297 patients were included, 87 of whom underwent OPSII and 210 of whom underwent MIBR. After a median follow-up of 39.5 months, local recurrence had occurred in 3 patients in the OPSII group (3.4%), and in 13 patients in the MIBR group (6.1%) (p = 0.408). The three-year L-DFS rates were 95.1% for OPSII and 96.2% for MIBR (p = 0.286). The three-year R-DFS rates were 100% and 96.4%, respectively (p = 0.559). The three-year D-DFS rate were 90.7% and 89.7% (p = 0.849). The three-year OS rates were 95.7% and 95% (p = 0.394). BREAST-Q highlighted significant advantages in physical well-being for OPSII. No difference was shown for satisfaction with breasts (p = 0.656) or psychosocial well-being (p = 0.444). OPSII is safe and effective after NAC. It allows oncological and aesthetic outcomes with a high QoL, and is a safe alternative for locally advanced tumors which are partial responders to NAC

Diagnosis and management of breast lymphoma: A single-institution retrospective analysis

Background: Breast lymphoma (BL) is a rare entity. Although mimicking clinical presentation and radiological features of epithelial breast malignancies, prognosis and treatment management are different. Here we report our single institution experience in such population.Methods: The database of our pathology institute was retrospectively searched for breast neoplasms coded as lymphoma from January 2000 to January 2017. The assessed data were: gender, age at diagnosis, laterality, stage (primary or secondary), histopathological diagnosis and grading (high vs. low) treatment, recurrence and survival status. Progression-free survival (PFS), overall survival (OS) and 5-year recurrence rate were estimated. An exploratory analysis comparing survival (PFS, OS and 5-year recurrence rate) between high- and low-grade histotypes and primary and secondary stages was performed.Results: Fifteen patients were included in the analysis. All patients were affected by B-cell type lymphomas; the most frequent subtype was diffuse large B-cell lymphoma (DLBCL). Patients affected by high-grade lymphomas were treated with polychemotherapy followed in about half of cases by consolidative ipsilateral breast radiotherapy. Patients affected by low-grade lymphomas were treated with local treatment only (surgical resection +/- radiotherapy). No patient received radical surgery or axillary dissection. At a median follow up of 9 years, four patients had relapsed (all affected by high-grade lymphomas) with central nervous system (CNS) involved in half cases. Both median PFS and OS were not reached, but a slight trend toward a better survival was noticed in favor of primary breast lymphoma (PBL), while a clearer survival benefit was observed in the low-grade cohort. The estimated 5-year survival rate was 77% within the whole population, 78% vs. 66% for primary vs. secondary and 100% vs. 66% for low-grade vs. high-grade BL.Conclusions: Our data concerning clinical and pathological features are consistent with those previously reported. Management of disease was based on histology. Although being a rare disease it is mandatory to take it into account for differential diagnosis since treatment and prognosis differs widely from primary breast malignancies

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

The modern concept of breast conserving surgery

The achievement on the biological behaviour and natural history of breast cancer demonstrates the same effectiveness and oncological safety of breast conserving surgery (BCS) followed by radiotherapy than mastectomy. The goal of BCS for patients with early-stage breast cancer is the complete removal of the tumor keeping sufficient surgical margins and maintaining at the same time the natural shape and appearance of the breast. In particular oncoplastic surgery (OPS) is a hybrid approach that combines oncologic principles and plastic surgical technique in order to ensure oncologically safe resection and satisfying cosmetic results. Oncoplastic breast surgeons need to become familiar with main techniques: volume displacement techniques and volume replacement techniques. Based on our experience and reviewing existent literature we described different oncoplastic techniques with specific indications and contraindications in order to standardized them. We also focused our attention on outcomes of OPS. Nowadays, it's not acceptable in the surgical management of breast cancer not taking care of oncological and cosmetic needs of individual patients. Oncoplastic preserving surgery is oncologically safe and allows to excise the tumor with negative margins without compromising aesthetic outcome. Oncoplastic breast surgery can be applied in larger tumors, resulting in comparable postoperative complications, resection margins and re-excision rates compared to standard lumpectomy. The excitement related to this procedure comes from reported data that seem to demonstrate a higher oncological safety and better cosmetic efficacy
