Metastase located within the proximal bronchial tree as defined in RTOG 0236 (refer to Appendix 1: Rules for SABR administration according to tumour location) or within the brain are not eligible for SABR treatment in the present study. However, it can be considered as a not treated evaluable metastase.\n- WHO performance status of 0-1\n- Evaluation by a radiation oncologist within 45 days prior to study registration, including imaging workup to document metastases (cf. description in assessment section)\n- Patients must have adequate organ function defined by the following laboratory results obtained within 28 days prior to the first study treatment: - Absolute neutrophil count of ≥ 1500/mm3; - Lymphocyte count ≥ 500 mm3; - Platelets ≥ 100,000/mm3; - Hemoglobin > 9 gr/dL; - Clearance Creatinine ≥ 50 mL/min; - Total bilirubin ≤ 1.5X ULN (unless Gilbert where 3X ULN is permitted); - Serum ALT and AST ≤ 2.5X ULN (unless documented liver metastases where ≤ 5X ULN is permitted), - ALK ≤ 2.5 ULN (unless documented bone or liver metastases where ≤ 5X ULN is permitted).\n- Life expectancy of more than 3 months\n- Patients must be aware of the investigational nature of the therapy and provide written informed consent.\n- Sexually active women of childbearing potential must agree to use a highly effective method of contraception supplemented with a barrier method, or to abstain from sexual activity during the study and for at least 5 months after the last dose of atezolizumab Sexually active males patients must agree to use condom while on SABR treatment and for at least 90 days after SABR treatment. Taking into account the irradiated area, use of condom after SABR treatment can be shortened at investigator discretion. Also, their women of childbearing potential partner should use a highly effective method of contraception. Women who are not postmenopausal (≥ 12 months of non-therapy-induced amenorrhea) or surgically sterile must have a negative serum β-HCG pregnancy test result within 7 days prior to initiation of study drug. A list of highly effective birth control methods and the definition of a woman of childbearing potential are provided in the core protocol (section 4.1)."}
