Algorithm for Determining Cisplatin-Eligibility in MIBC








                                              Patient is otherwise fit for cisplatin (ideally meeting the following Galsky criteria)
                                              • WHO or ECOG performance status <2, or Karnofsky performance status >60-70%                        No
                                              • CTCAE v5 grade <2 peripheral neuropathy
                                              • CTCAE v5 grade <2  audiometric hearing loss
       eGFR (CKD-EPI  preferred) and/or       • NYHA class <III heart failure
       24-h urine collection if feasible
                                                                                                     Yes

                  eGFR > 60 mI/min                              eGFR > 50 mI/min                             eGFR 40-50 mI/min                               eGFR <40 mI/min

                                                       Consider the following nephrotoxicity mitigation strategies:
                                                       • Decompression if acute obstructive uropathy is present
                                                       • Nephrology consultation before cisplatin administration
                                                       • Aggressive hydration before, during and after treatment
                                                       • Minimize concomitant nephrotoxic medications
                                                       • Dose reduction of conventional cisplatin regimes (25-50%)
                                                       • Cisplatin dose fractionation using the split-dose gemcitabine

                                                          and cisplatin regimen (cisplatin 35 mg/m on day 1 and day 8)
