Oncoplastic Breast Consortium consensus conference on nipple-sparing mastectomy
Purpose Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally
advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus
conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research
based on published evidence and expert panel opinion.
Methods The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate. Panelists
presented evidence summaries relating to each topic for debate during the in-person consensus conference. The iterative
process in question development, voting, and wording of the recommendations followed the modified Delphi methodology.
Results Consensus recommendations were reached in 35, majority recommendations in 24, and no recommendations in the
remaining 12 questions. The panel acknowledged the need for standardization of various aspects of NSM and immediate
reconstruction. It endorsed several oncological contraindications to the preservation of the skin and nipple. Furthermore, it
recommended inclusion of patients in prospective registries and routine assessment of patient-reported outcomes. Considerable heterogeneity in breast reconstruction practice became obvious during the conference.
Conclusions In case of conflicting or missing evidence to guide treatment, the consensus conference revealed substantial
disagreement in expert panel opinion, which, among others, supports the need for a randomized trial to evaluate the safest
and most efficacious reconstruction techniques
Optimal adjuvant treatment for patients with HER2-positive breast cancer in 2015
The introduction of trastuzumab as adjuvant treatment for patients with HER2-positive breast cancer changed the natural course of early-stage disease. Currently, one year of trastuzumab given concurrently with a taxane and following an anthracycline regimen is the preferred standard of care in Europe. The first attempt to escalate this approach, though the implementation of dual HER2 blockade with lapatinib added to trastuzumab, as assessed by the ALTTO trial, failed to improve further clinical outcomes; clinical assessment of the adjuvant trastuzumab/pertuzumab regimen is still ongoing in the APHINITY trial. Negative results were also reported for the addition of bevacizumab to adjuvant trastuzumab treatment within the context of the BETH study. Similarly, efforts to de-escalate through shortening the duration of adjuvant trastuzumab treatment failed (the PHARE trial), whereas others are still ongoing. Of note, evidence supports the use of lighter chemotherapy regimens with one year of adjuvant trastuzumab as backbone, for women with small HER2-positive breast tumors, where the omission of anthracyclines did not compromise the clinical outcome. Despite the successes achieved so far, a proportion of women with early-stage HER2-positive breast cancer, will still experience disease recurrence. The identification of these women is urgently needed, as well as the identification of predictive biomarkers to dictate the optimal treatment strategy. So far, HER2 expression status has been the only validated predictive biomarker for this patient population. Despite the clear association of pCR achieved through neoadjuvant trastuzumab-based chemotherapy with clinical outcome, results from neoadjuvant trials have not been always consistent with what was seen in the adjuvant setting. Similarly, inconsistent results have been reported for the predictive ability of alterations affecting the PI3K signaling pathway or the quantification of tumor infiltrating lymphocytes. In the era of personalized oncology, rigorous translational and clinical collaborative efforts are needed to further advance the field of treatment of patients with HER2-positive breast cancer.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Oncoplastic breast consortium recommendations for mastectomy and whole breast reconstruction in the setting of post-mastectomy radiation therapy
Aim: Demand for nipple- and skin- sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. Methods: A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. Results: The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recommendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. Conclusions: The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BR © 2022 The Author
