Brief Title  ICMJE Immune Mechanisms After Radiofrequency Ablation of Pulmonary Metastases From Colorectal Cancer Origin
Official Title  ICMJE Immune Mechanisms After Radiofrequency Ablation of Pulmonary Metastases From Colorectal Cancer Origin- ARFIM Study
Brief Summary Local percutaneous thermal ablation is frequently proposed in the management of metastatic diseases. Radiofrequency ablation (RFA) has demonstrated good results when the metastatic disease is limited and slowly evolving. The destruction of solid metastasis by RF leads to inflammatory and immunological mechanisms that remain poorly understood. These pathological events may influence the overall and anti-tumor host immune responses. The purpose of the study is to identify and quantify some immune mechanisms triggered by RFA of pulmonary metastases from colorectal cancer origin.
Detailed Description RFA could provide activatory signals and become a source of tumor antigens for the immune system. Generating a massive and transient release of antigens, RFA could boost lymphocyte proliferation and production of inflammatory cytokines in response to tumor extracts. Herein, the investigator aims to demonstrate that RFA can amplify the specific T cell response in metastatic cancer patients. In order to ensure this, he plans to assess and quantify tumor infiltrating lymphocytes through tumoral biopsies. He also plans to measure the CD4, CD8 and NK lymphocytes release, the circulating DNA and tumoral cells release, during RFA of lung metastases. On tumoral biopsies, the expression of PDL-1 ligand will also be evaluated and measured. Participants with bilateral metastases or with 5 or more unilateral metastases will be recruited. The two RFA interventions will be carried out within 4-6 weeks of each other. Blood samples and tumoral biopsies will be performed during each intervention. Biopsies will be performed on a metastasis before the thermal ablation. Blood samples will be performed just before RFA, 30 min after RFA and one day after. Analysis, identification and measure of lymphocytes release will be performed with flow cytometry. All analysis and measurements will be performed in the Bio-Pathology department of Institut Bergonié.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Other
Condition  ICMJE
  • Immune Evasion, Tumor
  • Neoplastic Cells, Circulating
  • Circulating Tumor Cell
  • Pulmonary Metastasis
  • Colo-rectal Cancer
Intervention  ICMJE Radiation: RFA interventions
Each patient is treated with 2 RFA interventions. Abiopsy of one metastasis is done at each RF session. Histological samples are sent to the Bio-pathology department of Institut Bergonié for tumor infiltrating lymphocytes counting. Primary outcome results from this counting (stromal TILs ≥ 20% is considered as a significant level, a comparative measurement before and after RF will be performed). In parallel blood samples are performed before and after RFA to analyze the kinetics of peripheral blood T lymphocytes subsets, tumoral circulating cells and tumoral DNA.
Study Arms  ICMJE Experimental: Single arm
Each patient is treated with 2 RFA interventions.
