Overview
Brief Summary
The proposed theory is based on combination of radiation therapy with usual targeted therapies capable of ADCC (Antibody-Dependant Cell Cytotoxicity). This association could enhance in a additive/synergistic way the benefic impact of immune system activation on tumor control. Stereotactic Body Radio-Therapy (SBRT) will be combined with the first line chemotherapy for metastatic breast, colorectal or VADS (upper aerodigestive tract) cancers. The IRAM study objective is to highlight a possible abscopal effect of this combination for metastatic cancer patients.
Detailed Description
Nowadays, metastatic cancer treatment is evolving with systemic treatments (target therapies and immunotherapies). Combinations and new therapeutic schemes have recently boosted the interest for an effect called "abscopal". This effect is based on the immune-stimulating effect of high doses ionizing radiations, but also on synergistic association with systemic treatment with immunologic mechanisms. This effect could enhance the tumor local control, but also its distant control. Numerous preclinical evidences as well as some clinical case reports described the abscopal effect. Ongoing clinical studies are investigating with radiotherapy abscopal effect alone, or associated with immunotherapies (anti-CTLA-4, PD-1 or PDL-1). The present study proposes a new association, based on an original biological rational. The proposed theory is based on combination of radiation therapy with usual targeted therapies capable of ADCC (Antibody-Dependant Cell Cytotoxicity). This association could enhance in an additive/synergistic way the benefic impact of immune system activation on tumor control. In the present study, Stereotactic Body Radio-Therapy (SBRT) will be combined to the standard systemic treatment for first line treatment of metastatic breast, colorectal and VADS (upper aerodigestive tract) cancers. Indeed, these treatments have in common the use of target therapies capable of ADCC. The IRAM study objective is to highlight a possible abscopal effect of this combination for metastatic cancer patients.

Outcomes
Primary Outcomes
Survival rate without progression for patients with metastatic colorectal cancer
Time Frame: 9 months
The rate of survival without progression according to the RECIST (v1.1) criteria for patients with colorectal cancer will be calculated at 9 months after the beginning of the systemic treatment.
Survival rate without progression for patients with metastatic breast cancer
Time Frame: 18 months
The rate of survival without progression according to the RECIST (v1.1) criteria for patients with metastatic breast cancer will be calculated at 18 months after the beginning of the systemic treatment.
Survival rate without progression for metastatic head and neck cancer
Time Frame: 6 months
The rate of survival without progression according to the RECIST (v1.1) criteria for patients with head and neck cancer will be calculated at 6 months after the beginning of the systemic treatment.
Secondary Outcomes
- Progression-free survival (PFS)(5 years)
- Response rate on predetermined metastatic abscopal sites(3 months)
- Overall survival (OS)(5 years)
- Toxicity of the treatments combination(5 years)
- Response rate on the irradiated site(3 months)
