(A) Global evolution of eGFR at start (D0) and after one, six, twelve months (M1, M6, M12) and at last follow-up (*P < 0.05). (B) Comparison of initial eGFR (D0) and eGFR at last follow-up between patients receiving Ifosfamide or Ifosfamide+cisplatin (*P < 0.05). D0, Day 0; M1, M6, M12, Months 1, 6, 12.
