Primary Invasive Paget's Disease in a Clinical Practice: A Case Report.

Invasive Paget's disease (IPDN) is a rare phenomenon characterised by invasive carcinoma localised to the nipple. It is associated with Paget's disease of the nipple (PDN) whereby Paget cells locally invade the underlying epidermis. Often in PDN, histopathological confirmation is needed, due to a lack of clear symptoms on clinical presentation. An 82-year-old female with single duct ectasia presented to the breast clinic in September 2023 with a tender, inflamed right nipple with a necrotic appearance. The lesion was excised, and an ultrasound scan showed right U2, implying no underlying malignancy. Microscopy showed Paget's disease with underlying ductal carcinoma in situ and two small (0.4 and 0.3mm) foci of dermal invasion by Paget cells in keeping with IPDN. Research suggests that dermal invasion by Paget cells has little effect on clinical outcome and prognosis depends largely on the associated underlying malignancy. However, all cases of IPDN with deep invasion or penetration of Paget cells into the dermis have the potential for regional and distant lymphatic spread. In extramammary Paget's disease, depth of invasion has been associated with poorer survival. Therefore, wide variability in clinical patterns and presentations of PDN mandates that a careful clinical approach correlated with in-depth histopathological evaluation is adopted in all cases.

New Alternative Techniques for Sentinel Lymph Node Biopsy.

Background and Objectives: This review paper highlights the key alternatives to the blue dye/radioisotope method of sentinel lymph node biopsy (SLNB). It analyses the research available on these alternative methods and their outcomes compared to the traditional techniques. Materials and Methods: This review focused on fifteen articles, of which five used indocyanine green (ICG) as a tracer, four used magnetic tracers, one used one-step nucleic acid amplification (OSNA) and Metasin (quantitative reverse transcriptase-polymerase chain reaction), one used the photosensitiser talaporfin sodium, one used sulphur hexafluoride gas microbubbles, one used CT-guided lymphography and two focused on general SLNB technique reviews. Results: Of the 15 papers analysed, the sentinel node detection rates were 69-100% for indocyanine green, 91.67-100% for magnetic tracers, 81% for talaporfin sodium, 9.3-55.2% for sulphur hexafluoride gas microbubbles, 90.5% for CTLG and 82.7-100% for one-step nucleic acid amplification. Conclusions: Indocyanine green fluorescence (ICG) and magnetic tracers have been proven non-inferior to traditional blue dye and isotope regarding SLNB localisation. Further studies are needed to investigate the use of these techniques in conjunction with each other and the possible use of language learning models. Dedicated studies are required to assess cost efficacy and longer-term outcomes.

Innovations and Challenges in Breast Cancer Care: A Review.

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.

Ethnicity and breast cancer in the UK: Where are we now?

Outcomes from breast cancer for women in the UK have improved significantly over recent decades. These gains are largely attributable to a combination of earlier diagnosis and access to treatments delivered to patients by the National Health Service irrespective of cost. Ethnic minority groups make up almost fifteen percent of the UK population and there is concern however that these groups may have poorer outcomes from the disease. In this short report we seek to summarise what the current evidence tells us about the patterns of breast cancer incidence and outcomes in ethnic minority women in the UK in order to raise awareness about this topic and provide consideration for what future research is needed to address the gaps that may exist.

The Journey of Prepectoral Breast Reconstruction through Time.

BACKGROUND: The facet of breast reconstruction has evolved from complex surgery to simple implant-based breast reconstruction. Minimal invasive surgery or Prepectoral breast reconstruction has revolutionised the surgical treatment for breast cancer and became a reality due to advances in meshes and implants. In this review, we have looked at the journey of Prepectoral implant beast reconstruction through time. METHODS: We conducted a literature review on pre-pectoral breast reconstruction, emphasising types of cover, its outcomes, complications, and the effect of postmastectomy radiotherapy. RESULTS: Prepectoral breast reconstruction had advanced with time and appears to be a safe and effective method of breast reconstruction and is associated with minimal morbidity whilst providing adequate cosmesis. Radiotherapy seems to be well tolerated with early favourable results. The Implant loss rates in the Acellular Dermal Matrix (ADM) to be around 5%-6% and rippling appear to be a common adverse effect of this technique ranging from 0%-35% in various studies. CONCLUSION: Prepectoral implant-based breast reconstruction has emerged as a successful method of breast reconstruction.

Implant-based Prepectoral Breast Reconstruction: The Importance of Oncoplastic Plane, its Blood Supply and Assessment Methods.

With the recent rise in prepectoral breast reconstruction, partly due to the improvement in implants and the aesthetic results but, more so, due to the perseveration of the pectoralis major, it is of great importance to have an appreciation of the clinical anatomy with regards to the breast and its blood supply for the practice of prepectoral breast reconstruction. The preservation of the mastectomy flap vasculature together with meticulous surgical technique minimizes complications, notoriously of skin flap necrosis. We aimed to describe the anatomy of the oncoplastic plane (for the prepectoral technique), its vasculature, and relevant assessment methods.

Symptomatic breast services in the post-COVID-19 era.

The COVID-19 pandemic has necessitated unprecedented changes to the functioning of hospitals across the world. This article evaluates the acute impact of COVID-19 on the provision of symptomatic breast services in the UK and explores suggestions for more sustainable functioning of services in the post-COVID-19 era.

Current margin practice and effect on re-excision rates following the publication of the SSO-ASTRO consensus and ABS consensus guidelines: a national prospective study of 2858 women undergoing breast-conserving therapy in the UK and Ireland.

INTRODUCTION: There is variation in margin policy for breast conserving therapy (BCT) in the UK and Ireland. In response to the Society of Surgical Oncology and American Society for Radiation Oncology (SSO-ASTRO) margin consensus ('no ink on tumour' for invasive and 2 mm for ductal carcinoma in situ [DCIS]) and the Association of Breast Surgery (ABS) consensus (1 mm for invasive and DCIS), we report on current margin practice and unit infrastructure in the UK and Ireland and describe how these factors impact on re-excision rates. METHODS: A trainee collaborative-led multicentre prospective study was conducted in the UK and Ireland between 1st February and 31st May 2016. Data were collected on consecutive BCT patients and on local infrastructure and policies. RESULTS: A total of 79 sites participated in the data collection (75% screening units; average 372 cancers annually, range 70-900). For DCIS, 53.2% of units accept 1 mm and 38% accept 2-mm margins. For invasive disease 77.2% accept 1 mm and 13.9% accept 'no ink on tumour'. A total of 2858 patients underwent BCT with a mean re-excision rate of 17.2% across units (range 0-41%). The re-excision rate would be reduced to 15% if all units applied SSO-ASTRO guidelines and to 14.8% if all units followed ABS guidelines. Of those who required re-operation, 65% had disease present at margin. CONCLUSION: There continues to be large variation in margin policy and re-excision rates across units. Altering margin policies to follow either SSO-ASTRO or ABS guidelines would result in a modest reduction in the national re-excision rate. Most re-excisions are for involved margins rather than close margins.

Youngest case of ductal carcinoma in situ arising within a benign phyllodes tumour: A case report.

INTRODUCTION: Phyllodes tumour (PT) is a rare tumour of the female breast. The tumour clinically and radiologically mimics the features of a fibroadenoma. Ductal carcinoma in situ (DCIS) in the epithelial component of PT is a very rare finding. PRESENTATION OF CASE: We present youngest ever case of a 23-year-old nulliparous woman with high-grade ductal carcinoma in situ arising within a benign phyllodes tumor. Macroscopically, it is a homogeneous tumour with solid components. Microscopically, it features typical leaf-like pattern with hypercellular stroma with high-grade ductal carcinoma in situ. DISCUSSION: To date, eight such rare cases of benign phyllodes tumour with ductal carcinoma in situ have been documented. We report the youngest case known in literature so far. CONCLUSION: As this is a very rare presentation, it poses several challenges in regard to both management and follow-up.
