Más betegség

• History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT-scan

• Active tuberculosis

Egyéb

• Banff score for ACR ≥ 3 on liver biopsy performed before the initiation of the treatment
• Pregnant or breastfeeding woman
• Patient not affiliated to a beneficiary or entitled social security scheme or to the PUMA
• Patient not having signed consent
• In case of proteinuria > 1g in 24 hours

• All patients over 18 and under 90 years old:
• who underwent LT more than 6 months ago (to prevent the higher risk of ACR which exists within the first months after LT and to deal with populations with a lowered immunosuppressive regimen long after LT)
• with HCC recurrence diagnosis according to the EASL diagnostic criteria (33)
• with advanced HCC not accessible to surgery and locoregional treatment
• with at least one measurable untreated lesion
• With a proposal for Atezo-Beva in first line treatment made in a multidisciplinary meeting
• Adequate hematologic and end-organ function, defined by the following laboratory test results, obtained within 14 days prior to initiation of study treatment, unless otherwise specified:
  • ANC ≥ 1.5 x 109/L (1500/µL) without granulocyte colony-stimulating factor support
  • Lymphocyte count ≥ 0.5 x 109/L (500/µL)
  • Platelet count ≥ 75 x 109/L (75,000/µL) without transfusion
  • Hemoglobin ≥ 90 g/L (9 g/dL). Patients may be transfused to meet this criterion.
  • AST, ALT ≤ 5 x upper limit of normal (ULN)
  • Serum bilirubin ≤ 3x ULN
  • creatinine clearance≥40 mL/min (calculated using the Cockcroft-Gault formula)
  • For patients not receiving therapeutic anticoagulation: INR or aPTT ≤ 2x ULN
  • Urine dipstick for proteinuria < 2+ (within 7 days prior to initiation of study treatment). Patients discovered to have ≥ 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate <1 g of protein in 24 hours
• ECOG Performance Status of 0 or 1
• For women of childbearing potential and men: agreement to remain abstinent or use effective contraception during treatment and at least :
  • 5 months after the end of the treatment with atezolizumab,
  • 6 months after the end of the treatment with bevacizumab
