Local Therapy Optimization by Grouping Immune-modulation With Cryoablation (LOGIC) for High Risk Breast Cancers
Summary Points: 1. High Risk Breast Cancers: Triple negative cancer is considered high risk due to high rate of local and systemic failure. Newer innovative treatment strategies are needed to improve systemic control of disease and survival. 2. Immune system modulation: is an emerging modality in cancer treatment. Tumor antigens can stimulate T cells to identify and destroy cancer cells. Cancers express "altered self" antigens that tend to induce weaker responses than the "foreign" antigens expressed by infectious agents. Thus, immune stimulants and adjuvant approaches have been explored widely. Opportunities to develop effective cancer vaccines may benefit from seminal recent advances in understanding how immunosuppressive barricades are erected by tumors to mediate immune escape. This concept is precisely applicable to triple negative breast cancer due to their antigenicity. Checkpoint inhibitors are an attractive method for treatment of high-risk breast cancers. However, to leverage the efficacy of checkpoint inhibition, approaches are needed to enhance delivery of cancer antigens to the T cells. 3. Cryoablation: offers an efficacious and safe method to enhance tumor antigen presentation to the immune cells while destroying the primary tumor. This ablation method is superior by virtue of antigen preservation in situ despite toxicity to the tumor cell. Impact of cryoablation in enhancing immunological responses in tumor microenvironment are well established; however, cryoablation can also cause tumor antigen tolerance via non-specific stimulation of T cells. 4. Rationale for combining cryoablation and checkpoint inhibitors: Since checkpoint inhibitors curtail the tolerance developed by tumor antigens, and cryoablation enhances antigen presentation and T cell recruitment, it is intuitive that combination of these two approaches presents an ideal opportunity to leverage the benefits of both approaches while curtailing the limitations of either. Therefore, the investigators hypothesize in this study that their combination will improve the response rate and the degree of response.

A Single-center, Blinded, Efficacious, Phase III Randomized Clinical Trial Initiated by Investigators to Investigate the Use of Surface Guided Radiation Therapy (SGRT) in Combination With Deep Inspiration Breath Hold (DIBH) Technique for Left Breast Cancer Treatment, Compared to Traditional Laser Alignment With Free Breathing Treatment
This study is a single-center,blinded, efficacious, phase III randomized clinical trial initiated by investigators. The primary objective is to investigate the use of Surface Guided Radiation Therapy (SGRT) in combination with Deep Inspiration Breath Hold (DIBH) technique for left breast cancer treatment, compared to traditional laser alignment with free breathing treatment. This approach offers superior positioning accuracy and improved heart protection without any increase in radiation or adverse reactions.

Characterization and Kinetic of Chemotherapy-induced Cardiovascular Toxicity in Breast Cancer - PROTECT-COEUR
The combination of epirubicin-cyclophosphamide (EC) and paclitaxel (Tax) is one of the main chemotherapy treatments used in breast cancer patients. These treatments, which can be combined with anti-HER2 therapy using trastuzumab, are frequently associated with side effects including cardiac toxicity. However, this cardiac toxicity has only been demonstrated several months after treatment and using global indices such as ejection fraction. The assessment of myocardial dysfunction using regional deformations and the kinetic of this dysfunction during chemotherapy treatment has never been performed. In order to counteract these myocardial dysfunctions, it is essential to better describe the kinetic of the cardiac toxicity by initiating measurements since the beginning of the treatment, in order to be able to propose adapted countermeasures (e.g. exercise training) in parallel with the chemotherapy.

Pyrotinib Combined With Trastuzumab, Dalpiciclibe and Letrozole for HR+/HER2+ Breast Cancer:A Single Arm, Open Label, Phase II Trial
In this single arm, open label, phase 2 trial, operable patients with stage II-III HR+/HER2+ breast cancer will be enrolled and receive two cycles of pyrotinib combined with trastuzumab, dalpiciclib and letrozole. Imaging evaluation was performed two weeks later, and patients who achieved CR or PR were continued with the original regimen for 4 cycles. Subjects who did not achieve PR switched to regimen and received 4 cycles of pyrotinib combined with trastuzumab plus chemotherapy. This study aims to assessed the biological effects and safety of pyrotinib combined with trastuzumab, dalpiciclib and letrozole for HR+/HER2+ breast cancer in the neoadjuvant setting.

Évaluation de la Performance Diagnostique du dépistage du Cancer du Sein, Pour Une Seconde Lecture Des clichés de Mammographie assistée du Dispositif médical à Base d'Intelligence Artificielle MammoScreen
The goal of this clinical trial is to compare, for the second reading of screening mammograms, the standard of care with an AI assisted scenario. The main questions it aims to answer are: - will the experimental pathway be non-inferior to the standard pathway? - will the experimental pathway be economically superior to the standard pathway? Participants will receive screening mammograms, as part of the breast cancer screening program. Researchers will compare the interpretation made by the second reader in the standard pathway with the AI assisted interpretation made by a different reader in the experimental pathway.

Retrospective, Observational, Multicentric Study Aimed at Developing a Model for Prediction of Axillary Lymph Node Status After Neoadjuvant Chemotherapy in Breast Cancer Patients
The management of patients diagnosed with breast cancer (BC) with axillary nodal involvement is still a controversial topic. These patients' treatment usually involves the administration of a neoadjuvant chemotherapy (NAC) in order to improve survival rates and increase local disease control. Depending on the tumor subtype, an axillary pathologic complete response (pCR) is achieved in 40-70% of initially axillary node-positive patients (cN+). Concerning patients with an axillary pCR, thus a clinically negative node status (cN0), axillary lymphadenectomy (ALND) might be replaced by less invasive surgical approaches and sentinel lymph node biopsy (SLNB) is considered, in these cases, an effective alternative treatment. However, the relatively high false negative rates, reported in several validation trials, points out the complexity concerning these patients' treatment. Moreover, histological findings' predictive and prognostic value, after SLNB, of micrometastases and isolated tumor cells (ITCs) is still unclear. Currently, dual-tracer-guided lymph node biopsy and the surgical removal of ≥ 3 sentinel lymph nodes are known as effective strategies aimed to reduce the false negative rates. There are several ongoing clinical trials to understand and define the best approach for these patients. Nowadays, there's great interest in potential prognostic role of systemic inflammation's biochemical markers such as neutrophil-to-lymphocyte ratio (NLR). Systemic inflammation's markers may be nodal pCR's predictors after NAC in node-positive breast cancer patients. The aim of the study is to develop and validate a pre-operative model, able to predict pCR after NAC to select the patients suitable for a surgery de-escalation strategy.
