Inclusion Criteria

I1. Adult male or female patients (= 18 years of age at inclusion);, I2. Histologically or cytologically proven solid cancer at the oligometastatic stage amenable to pan-lesion SBRT, as defined by: a. [2-5] tumor lesions measurable as per RECIST V1.1 (including primary) with a largest diameter comprised between [1.5-5] cm, b. The disease can be either genuinely oligometastatic, oligoprogressive, or an induced oligometastatic disease, c. All tumor lesions that match criterion I2a must be eligible to SBRT in terms of location and radiotherapy constraints, d. SBRT to all lesions must be feasible over a two-week period, e. Whatever the primary tumor type;, Patients must agree to comply with biopsy and blood sampling for research purpose;, Minimal wash-out periods from last administration of treatments to the first day of SBRT must be: a. Systemic chemotherapy including cytotoxic, immunotherapy, targeted therapy, hormone therapy, any investigational agent > 4 weeks, b. Immunosuppressive medication > 4 weeks, with the exceptions of intranasal, topical, and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceeding 10 mg/day of prednisone, or an equivalent corticosteroid, c. Live attenuated vaccination > 4 weeks, d. Major surgery > 4 weeks;, WHO 0-1 and ECOG Performance Status 0-1;, Patients must have adequate organ function defined as follows: a. White blood cell count of = 1,500/mm3, b. Lymphocyte count of = 800/mm3, c. Platelet count of = 100,000/mm3, d. Hemoglobin > 9 g/dL, e. Serum ALT and AST =2.5 ULN (or if liver metastases are present must be = 5x ULN) f. Serum creatinine CL>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance;, Female patients must either be of non-reproductive potential or must have a negative serum pregnancy test within 3 days prior to the initiation of the study drug. Fertile men with a female partner of childbearing potential must agree to use male condom plus spermicide and childbearing potential women must have agreed to use at least one highly effective contraceptive method during treatment on this trial and for up to 1 month after the last dose of ATRA; Pregnancy testing and contraception counseling should be repeated monthly throughout the period of ATRA treatment., Patient should understand, sign, and date the written voluntary informed consent form prior to any protocol-specific procedures performed. Patient should be able and willing to comply with study visits and procedures as per protocol;, Patients must be affiliated to a social security system or beneficiary of the same.

Exclusion Criteria

Evidence of disease rapidly progressing at the time of screening according to the two last best-fitted imaging modalities (CT-scans, MRI, PET-scan), at the discretion of the investigator and the multidisciplinary board (RCP);, Patients with tumor(s) that invade major vessels, as shown unequivocally by imaging studies;, Patients with central lung metastasis (i.e within 2 cm from hilum) that are cavitary as shown unequivocally by imaging studies;, Persisting significant toxicities related to prior treatments i.e. = Grade 2 adverse event according to CTCAE V5.0 criteria, except for alopecia and biological values defined in inclusion criteria I6;, Known allergy or hypersensitivity to the study drug. The study drug is contraindicated in patients with soy or peanut allergy ;, Positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS);, Pregnant or breastfeeding women., Persons deprived of their freedom or under guardianship, or for whom it would be impossible to undergo the medical follow-up required by the trial, for geographic, social or psychological reasons., Any evidence of brain metastasis;, Any situation where irradiation of the target site(s) would imply re-irradiation of a formerly irradiated tumor site;, Bone metastasis located in a femoral bone if risk of pending fracture is high;, Liver metastasis adjacent to the stomach or small bowel and liver metastasis that leads to a volume of uninvolved liver < 700 cc;, Patients with any concurrent severe condition (grade 3 or beyond according to CTCAE V5.0) and/or uncontrolled medical condition that could compromise participation in the study;, Any psychiatric illness/social situations that would limit compliance with study requirements or compromise the ability of the subject to give written informed consent;, Active secondary malignancy unless the malignancy is not expected to interfere with the evaluation of safety and is approved by the Sponsor. Examples of the latter include basal or squamous cell carcinoma of the skin, in-situ carcinoma of the cervix, and isolated elevation of prostate-specific antigen. Patients with a completely treated prior malignancy who are no longer treated (including maintenance therapy) and no evidence of disease for = 2 years are eligible;, Chronic treatment with systemic corticosteroids or another immunosuppressant including, but not limited to systemic corticosteroids at doses exceeding 10 mg/day of prednisone or equivalent, methotrexate, azathioprine, and TNF-a blockers. Use of immunosuppressive medications for the management of investigational product-related AEs or in subjects with contrast allergies is acceptable. The use of topical, inhaled and intranasal corticosteroids is permitted;
