Innovations for the future of breast surgery

Bridging frontiers: The role of a Global Breast Research Working Group

Breast cancer remains a significant cause of death for women globally, despite advancements in detection and treatment, low- and middle-income countries face unique obstacles. Role of Research Working Group (RWG) can expedite research progress by fostering collaboration between scientists, clinicians, and stakeholders. Benefits of a Global RWG include pooling resources and expertise to develop new research ideas, addressing disparities, and building local research capacity, with the potential to improve breast cancer research and outcomes.

Non-surgical ablation for breast cancer: an emerging therapeutic option

Non-surgical ablation is emerging as an alternative local therapy option for patients with early-stage breast cancer and encompasses two main types of percutaneous therapeutic procedures: radiofrequency ablation and cryoablation. Both techniques involve obliteration of a spherical lesion and feasibility studies have shown that complete tumour ablation is achievable with good or excellent cosmetic results. Although few clinical studies have directly compared non-surgical ablation with conventional surgical resection, observational studies indicate that clinical outcomes are favourable with acceptable rates of local control and no detriment to long-term survival. There remain outstanding issues with these percutaneous ablative techniques that require resolution before they could be incorporated into routine clinical practice. Hence, a consensus meeting was convened to discuss the challenges of non-surgical ablation and clarify indications for its use alongside clinical management pathways. In this Policy Review we will address some of the broader biological aspects of non-surgical ablation, including immune-modulatory effects and potential novel applications for the future.

Evolution of Indocyanine Green Fluorescence in Breast and Axilla Surgery: An Australasian Experience

The evolution of indocyanine green (ICG) fluorescence in breast and axilla surgery from an Australasian perspective is discussed in this narrative review with a focus on breast cancer and reconstruction surgery. The authors have nearly a decade of experience with ICG in a high-volume institution, which has resulted in publications and ongoing future research evaluating its use for predicting mastectomy skin flap perfusion for reconstruction, lymphatic mapping for sentinel lymph node (SLN) biopsy, and axillary reverse mapping (ARM) for prevention of lymphoedema. In the authors' experience, routine use of ICG angiography during breast reconstruction postmastectomy was demonstrated to be cost-effective for the reduction of ischemic complications in the Australian setting. A novel tracer combination, ICG-technetium-99m offered a safe and effective substitute to the "gold standard" dual tracer for SLN biopsy, although greater costs were associated with ICG. An ongoing trial will evaluate ARM node identification using ICG fluorescence during axillary lymph node dissection and potential predictive factors of ARM node involvement. These data add to the growing literature on ICG and allow future research to build on this to improve understanding of the potential benefits of fluorescence-guided surgery in breast cancer and reconstruction surgery.

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.

Cell-free biomimetic polyurethane-based scaffold for breast reconstruction following non-malignant lesion resection. A first-in-human study

BACKGROUND

Based on the volume of tissue removed, conservative surgery (BCS) cannot always guarantee satisfactory cosmetic results, unless resorting to more complex oncoplastic approaches. Investigating an alternative to optimize aesthetic outcomes minimizing surgical complexity, was the purpose of this study. We assessed an innovative surgical procedure based on the use of a biomimetic polyurethane-based scaffold intended for regenerating soft-tissue resembling fat, in patients undergoing BCS for non-malignant breast lesions. Safety and performance of the scaffold, and safety and feasibility of the entire implant procedure were evaluated.

METHODS

A volunteer sample of 15 female patients underwent lumpectomy with immediate device positioning, performing seven study visits with six-month follow-up. We evaluated incidence of adverse events (AEs), changes in breast appearance (using photographs and anthropomorphic measurements), interference with ultrasound and MRI (assessed by two independent investigators), investigator's satisfaction (through a VAS scale), patient's pain (through a VAS scale) and quality of life (QoL) (using the BREAST-Q© questionnaire). Data reported are the results of the interim analysis on the first 5 patients.

RESULTS

No AEs were device related nor serious. Breast appearance was unaltered and the device did not interference with imaging. High investigator's satisfaction, minimal post-operative pain and positive impact on QoL were also detected.

CONCLUSIONS

Albeit on a limited number of patients, data showed positive outcomes both in terms of safety and performance, paving the way to an innovative breast reconstructive approach with a potential remarkable impact on clinical application of tissue engineering.

Effect of Cold Therapy on Managing Postoperative Pain Following Breast Conserving Surgery

BACKGROUND

Cold therapy is an important non-pharmacologic method used for pain relief.

AIM

In the present study, we aimed to evaluate the therapeutic effect of cold therapy on managing postoperative pain following breast-conserving surgery (BCS) and assess its effect on recovering quality.

METHOD

The study was planned and implemented as a randomized controlled clinical study. Sixty patients with breast cancer were included in this study. All patients underwent BCS at Istanbul Faculty of Medicine. There were 30 patients in both the cold therapy and control groups. In the cold therapy group, a cold pack was placed around the incision line for 15 minutes every hour from the first hour after the operation until the 24th hour. To all the patients in both groups, pain levels were measured by visual analog scale (VAS) at the postoperative 1st, 6th, 12th, and 24th hours, respectively, and the quality of recovery was evaluated by a Quality of Recovery-40 questionnaire at the postoperative 24th hour.

RESULTS

The patients' median age was 53 (range: 24-71). All patients were T1-2 clinically and had no lymph node metastasis. Interestingly, the mean of pain level in the cold therapy group was statistically significantly lower in the first 24 hours (1st, 6th, 12th, and 24th hours) of the postoperative period (p = .001). Notably, the cold therapy group had higher recovering quality than the control group. In the first 24 hours, only 4 (12.5%) patients in the cold therapy group received additional analgesics, whereas all patients (100%) in the control group received additional analgesics (p = .001).

CONCLUSIONS

Cold therapy is an easy and effective non-pharmacologic method for pain relief after BCS in patients with breast cancer. Cold therapy reduces the acute pain of the breast and contributes to the quality of recovery of those patients.

Breast Cancer Surgery: New Issues

Since ancient times, breast cancer treatment has crucially relied on surgeons and clinicians making great efforts to find increasingly conservative approaches to cure the tumor. In the Halstedian era (mid-late 19th century), the predominant practice consisted of the radical and disfiguring removal of the breast, much to the detriment of women's psycho-physical well-being. Thanks to enlightened scientists such as Professor Umberto Veronesi, breast cancer surgery has since impressively progressed and adopted a much more conservative approach. Over the last three decades, a better understanding of tumor biology and of its significant biomarkers has made the assessment of genetic and molecular profiles increasingly important. At the same time, neo-adjuvant treatments have been introduced, and great improvements in genetics, imaging technologies and in both oncological and reconstructive surgical techniques have been made. The future of breast cancer management must now rest on an ever more precise and targeted type of surgery that, through an increasingly multidisciplinary and personalized approach, can ensure oncological radicality while offering the best possible quality of life.
