Background and Objectives: Wide local excision is a common procedure in the treatment of breast cancer. Wire-guided localisation (WGL) has been the gold standard for many years; however, several issues have been identified with this technique, and therefore, wire-free techniques have been developed. This scoping review synthesises the available literature comparing wire-guided localisation with the wire-free techniques used in breast-conserving cancer surgery. Materials and Methods: Multiple databases including Pubmed and MEDLINE were used to search articles between 1 January 2000 and 31 December 2022. Terms included “breast neoplasms”, “margins of excision”, and “reoperation”. In total, 34/256 papers were selected for review. Comparisons were made between positive margins and re-excision rates of WGL with wire-free techniques including SAVI SCOUT, Magseed, ROLL, and RSL. Pooled p-values were calculated using chi-square testing to determine statistical significance. Results: Pooled analysis demonstrated statistically significant reductions in positive margins and re-excision rates when SAVI SCOUT, RSL, and ROLL were compared with WGL. When SAVI SCOUT was compared to WGL, there were fewer re-excisions {(8.6% vs. 18.8%; p = 0.0001) and positive margins (10.6% vs. 15.0%; p = 0.0105)}, respectively. This was also the case in the ROLL and RSL groups. When compared to WGL; lower re-excision rates and positive margins were noted {(12.6% vs. 20.8%; p = 0.0007), (17.0% vs. 22.9%; p = 0.0268)} for ROLL and for RSL, respectively {(6.8% vs. 14.9%),(12.36% vs. 21.4%) (p = 0.0001)}. Magseed localisation demonstrated lower rates of re-excision than WGL (13.44% vs. 15.42%; p = 0.0534), but the results were not statistically significant. Conclusions: SAVI SCOUT, Magseed, ROLL, and RSL techniques were reviewed. Pooled analysis indicates wire-free techniques, specifically SAVI SCOUT, ROLL, and RSL, provide statistically significant reductions in re-excision rates and positive margin rates compared to WGL. However, additional studies and systematic analysis are required to ascertain superiority between techniques.

BackgroundThe rate of upgrading ductal carcinoma in situ (DCIS) to invasive cancer varies widely in the literature with no consensus regarding sentinel lymph node biopsy (SLNB) for DCIS; however, some guidelines do recommend it in the event of a mastectomy. The primary aim of this study was to determine the upgrade rate of DCIS to invasive carcinoma (IC) in patients undergoing mastectomy for DCIS and identify the clinicopathological predicting factors for the upgrade. The secondary aim was to determine the SLNB positivity rate. MethodologyWe retrospectively analysed consecutive patients with DCIS diagnosed through a biopsy who then underwent mastectomy over a 10-year period (2010 to 2020). Clinical, radiological, and histological variables were collected from medical records. ResultsWe studied 143 women (mean age = 57.4 years, range = 26-85 years) who underwent mastectomy for DCIS identified on biopsy. Almost two-thirds (62.9%, 90/143) of the patients were detected on screening mammography, while 35.6% (51/143) were diagnosed following presentation with either an area of palpable concern or nipple discharge. The most common mammographic presentation of DCIS was calcification (83.9%, 120/143), and, in 85.9% of the patients, the mammographic lesion was more than 20 mm. Highgrade DCIS was noted in 76.9% of preoperative biopsy results, while the rest was either low or intermediategrade DCIS. Overall, 24.5% (35/143) were upgraded to IC (upgraded group) on postoperative histology, whereas 108/143 remained DCIS postoperatively (pure DCIS group). The positivity rate of SLNB was 4.8%. Multifocality was the only significant predictor of IC on multivariate analyses of clinicopathological predictors (odds ratio = 3.0, 95% confidence interval = 1.0-8.7). The presence of comedonecrosis was higher in the upgraded group compared to the pure DCIS group (42.9% vs. 27.8%), but this was not statistically significant. ConclusionsIn our study cohort, nearly one in four (24.5%) patients were upgraded from DCIS to IC on postoperative histology, with an SLNB positivity rate of 4.8%. This is important when counselling patients regarding the risk of coincident occult IC and the importance of SLNB at the time of mastectomy. Multifocality on preoperative imaging was the only significant predictive factor. Based on this result, we recommend that SLNB should also be considered if patients have multifocal DCIS and planned for oncoplastic breastconserving surgery. However, further studies are required to investigate the association between multifocal DCIS and the risk of upgrading to IC.

Breast cancer care has seen tremendous advancements in recent years through various innovations to improve early detection, diagnosis, treatment, and survival. These innovations include advancements in imaging techniques, minimally invasive surgical techniques, targeted therapies and personalized medicine, radiation therapy, and multidisciplinary care. It is essential to recognize that challenges and limitations exist while significant advancements in breast cancer care exist. Continued research, advocacy, and efforts to address these challenges are necessary to make these innovations accessible to all patients while carefully considering and managing the ethical, social, and practical implications.

Background: The framework of breast care is changing rapidly due to the increasing success of systemic therapies for breast cancer and consequently, surgeons need to adapt themselves to the changing role of surgery in its management. Real-world evidence indicates that breast cancer patient-related outcomes are better if they are managed by specialized physicians and surgeons. On the other hand, the curriculum for the training of breast surgeons is expanding and includes skills that involve newer surgical techniques and non-surgical technologies. De-escalation of surgery and also the fact that quality of life is becoming one of the priorities in breast cancer management require breast surgeons to be competent in all aspects of multidisciplinary management. Classical teaching including master-apprentice relation-based training is no more sufficient to satisfy the expectations of the trainees. However, on the other hand, the sources for contemporary postgraduate education are relatively scarce when considering these fast changes in the field. Therefore, there is a continuing quest among breast surgeons for finding ways to maintain their professional development. Summary: Classrooms and operating theaters without walls that came with the internet boom brought substantial opportunities for breast surgeons. Platforms such as BreastGlobal, Breastics24h, Global Breast Hub, Oncoplastic Academy-Brazil, ibreastbook, Virtual Breast Oncoplastic Surgical Simulator and CluBreast helped surgeons who needed to get contemporary training and interaction for their professional continuous development. Networking sites such as YouTube, Facebook and Twitter are also among the social media platforms for professional groups to interact. National and global breast surgery societies also provide periodical online meetings and congresses for their members in order to satisfy the ongoing demand for training, interaction and networking. Therefore, web-based platforms helped many surgeons from different parts of the world who could not afford to travel or did not have time to attend the necessary meetings due to their limited time and resources. Moreover, these online programs may have also encouraged surgeons to pursue specialized training in breast surgery which in turn should be expected to increase the quality of breast care in their countries. Key messages: The platforms have downsides such as practical training and role modeling are limited and the opportunity of receiving real-time feedback on skills requirements lacks and networking would not be productive as expected. Nevertheless, web-based platforms require certain technology and infrastructure which still could not be provided everywhere.
