Brief Summary

The aim of our study is to examine the cryoimmunologic response and its mechanisms induced by US-guided cryoablation of small breast tumors (<2 cm) not eligible to neoadjuvant therapy. We will recruit 30 women who will undergo cryoablation and their results will be compared with a control group of 30 women, who will follow the same therapeutic pathway without performing cryoablation. All recruited patients will undergo an enrollment check, pre-cryoablation breast MRI and blood test to assess immune response, breast cancer US-guided cryoablation, post-cryoablation breast MRI and the same blood test to evaluate immunologic response. Within 21 days all patients will undergo breast surgery, with immuno-histopathological analysis on surgical specimen.

At least 10 days after surgery the patient will undergo clinical breast examination, blood test to assess immune response and patient satisfaction questionnaire.

Cryoablation treatment will be performed using a 14G cryoprobe under us-guidance for visualization of the ice ball surrounding the lesion. The ultrasound guide is used to ensure that the action affects the entire tumor and that therapeutic temperatures are reached in every part of the tumor.

Pre- and post- cryoablation breast MRI will be performed on a 3T magnet to assess cryoablation rate of success. Artificial intelligence algorithms will also be used for this purpose. Cryoablation treatment efficacy will also be evaluated with ultrasound.

The immunological fitness of cancer patients will be studied by flow cytometry, evaluating the presence of cytokines/chemokines relevant during anticancer immune response/tumor progression and for the presence of molecules released by cells during an immunogenic cell death.

The goal of our study will be to demonstrate that cryoablation of breast cancer can induce an antitumor immune response.

Therefore this approach could become an additional tool in the oncological treatment of breast cancer.

Detailed Description

We will enroll women with a biopsy-proven diagnosis of early-stage breast cancer (T1 N0), not eligible for neo-adjuvant therapy, scheduled to breast surgery (mastectomy or nodulectomy), who have given informed consent for the study.

We will recruit 30 women who will undergo cryoablation. Their results will be compared with those obtained from a control group of 30 women, who will follow the same therapeutic pathway for the treatment of breast cancer without performing cryoablation.

The primary objective of our study is the characterization of the Immunogenic Cell Death (ICD) induced, the inflammatory response and the modulation of circulating T immune cells induced by tumor cryoablation treatment in the serum of breast cancer patients.

The circulating ICD biomarkers HMGB1, calreticulin and HSP70/90 will be analysed and also the profile of Th1 and Th2 type cytokines (IFN-γ, IL-12 (p40/p70), IL-15, IL-17, IL-2, IL-7, IP-10, IL-13, IL-5, IL-4), pro-inflammatory cytokines (IL-1α, IL-1β, IL- 6, TNF-α, IL-1RA, IL-2R, IL-8, CRP, IL-17, IFN-α), immunosuppressive cytokines (TGF-β1, IL-10, PGE2), chemokines (CCL5/RANTES, CCL3/MIP-1α, CCL4/MIP-1β, CCL2/MCP-1, CXCL9/MIG, CCL11/Eotaxin). Immune cell subsets will be characterized by flow cytometry: besides the conventional immune cell subsets (NK, Monocyte, Granulocyte, T and B cells), specific T cell subsets (Treg, naïve, memory, central effector) will be characterized and also the expression of immune markers associated to activation (CD137) or suppression/exhaustion (PD1, CTLA4, TIM3, LAG3).

Secondary endpoints are:

1. Cryoablation treatment efficacy and safety

We will evaluate Recist criteria rate of complete response to cryoablation with breast ultrasound and breast MRI. Incidence vand severity of complications related to cryoablation will be monitored to establish safety profile ablating breast cancer with 10 mm margins around the primary tumor.

2. Cryoablation treatment capability to induce immunogenic tumor cell death.

The presence and the extent of tumor necrosis / apoptosis on surgical specimen sections stained with hematoxylin-eosin will be evaluated. Immunohistochemical tests will be used to verify the activation of apoptotic mechanisms and Immunogenic cell death activation.

3. Tumor microvesicles release following Cryoablation treatment. During cell death, microvesicles (MVs) released by the cell transport a complex molecular cargo that can act as source of antigen repertoire and activatory signals to Antigen Presenting cells (APCs). Tumor derived MVs released in the serum of the patients will be isolated by ultracentrifugation steps as preliously described. The isolated MVs will be tested for the expression of Calreticulin and HMGB1.

All enrolled patients will undergo series of check as shown below (ICE-STUDY STEPS) :

enrollment check (STEP 0), breast MRI pre-cryoablation treatment (STEP 1) and post-cryoablation treatment (STEP 4), breast cancer US-guided cryoablation

(STEP 2), blood test to assess immune response (STEP 1, STEP 3, STEP 4, SURGERY and STEP 5) and surgical specimen immuno-histopathological analysis.

Enrollment check (STEP 0) will be conducted by a radiologist and an oncologist, where the patient's medical history will be collected and a breast examination of the affected site will be performed. The patient will also undergo breast US to evaluate cryoablation treatment feasibility (distance >1 cm between the tumor and the skin, the nipple or the chest wall). If the patient is considered eligible to the study, the protocol will be illustrated in detail and informed consent will be collected.

Breast MRI will be performed pre-cryoablation (STEP 1) and post-cryoablation (STEP 4) to assess Visual-ICE ablation rate of success. Artificial intelligence algorithms will also be used for this purpose. Cryoablation treatment efficacy will also beevaluated with ultrasound (STEP 4).

STEP 2 consists in US-guided cryoablation treatment of the breast lesion.

Within 21 days from the enrollment the patient will undergo breast surgery and blood test.

During the Final STEP, the patient will undergo clinical breast examination, blood test to assess immune response and patient satisfaction questionnaire.

All cryoablation sessions will be performed under US-guidance by a single board-certi¿ed interventional radiologist. Biopsy, percutaneous cryoablation will be carried out using an argon-based cryoablation unit (BTG Cryoablation System).

Both preoperative US and MRI images will be compared in order to determine the correct positioning of the probe for tumor ablation. All the procedures will be carried out under local anesthesia given by injection of 2-5mL of 2% lidocaine proximal to the tumor lesion and along the course of the cryoprobes. One or more cryoprobes will be inserted into the targeted tumor using US guidance, through a small skin incision of 1-2mm. To avoid cryoinduced skin injury and facilitate the ablation of breast tissue at least 1cm beyond all apparent tumor margins, warming bags will be placed on the breast skin.

Due the relatively low heat load of breast parenchyma compared with internal organs, it was estimated that 1cm of visible ice beyond all the tumor margins would be necessary to generate cytotoxic temperatures (e.g.,-40¿C) throughout the breast tumor.

Each cryoablation treatment session consists in two cycles of 8 minutes of duration, followed by a 4-minute active thawing phase and a 4-minute passive thawing phase. The latter is considered useful to maximize cell death. US guidance will be also used to verify the formation of a homogeneous hypoechoic area, owing to the iceball, which encompassed the tumor all around and to detect early complications. The probes will be removed after the second phase of thawing, without the need for skin suture. After the procedure, the patients will be discharged in 2 hours a¿er the ablation, without any prescription.

The clinical outcome will be evaluated with US at the end of the cryoablation procedure and 7 days a¿er with clinical examination and MRI. The absence of such signs or symptoms will be interpreted as an optimal clinical result.

Immunogenic CELL DEATH and Inflammatory circulating Biomarkers will be analysed at different time points (5 time points:

before, 48 h and 7 days after cryoablation; before and after 10 days from surgery). Plasma will be isolated by EDTA treated blood (10 ml/sample) by centrifugation (4000 rmp/5'/4°C) and aliquoted and stored at -80°C.

The ICD biomarkers characterized will be: calreticulin, HMGB1, HSP70/90 (by ELISA and/or chemioluminescence immune sandwich tests).

Circulating Inflammatory mediators will also be analyzed by xMAP Multiplex platform including the following molecules:

Th1 and Th2 type cytokines (IFN-γ, IL-12 (p40/p70), IL-15, IL-17, IL-2, IL-7, IP-10, IL-13, IL-5, IL-4), pro-inflammatory

cytokines (IL-1α, IL-1β, IL-6, TNF-α, IL-1RA, IL-2R, IL-8, CRP, IL-17, IFN-α), immunosuppressive cytokines (TGF-β1, IL- 10, PGE2), chemokines (CCL5/RANTES, CCL3/MIP-1α, CCL4/MIP-1β, CCL2/MCP-1, CXCL9/MIG, CCL11/Eotaxin)] will be analyzed.

The samples of each patient will be analysed for each biomarker simultaneously to avoid inter-experiment bias.

Microvesicles will be isolated by ultracentrifugation steps in micro-method scale (2 mL of plasma) and the analysis of calreticulin and HMGB1 will be performed by flow cytometry/ELISA (3 Time point: before, 48h and at the end of the procedure) Immune phenotyping will be performed by mulitparametric flow cytometry, characterizing the immune cell subsets(NK, T, B cells, granulocyte, monocytes). T cell subsets will be specifically characterized for Treg (CD25/foxp3), Naive/memory effector memory T cell (CCR7/CD45RA) and for activatory or exhausted phenotype (CD137, ICOS, PD1, CTLA4, TIM3, LAG3).
