Background: This paper reports the toxicity of OPEC/OJEC chemotherapy in stage 4 neuroblastoma patients over 1 year of age.
Procedure: Ninety‐five patients with stage 4 neuroblastoma received alternating courses of OPEC/OJEC—vincristine 1.5 mg/m2 (O), cisplatin 80 mg/m2 (P), etoposide 200 mg/m2 (E), cyclophosphamide 600 mg/m2 (C), and carboplatin 500 mg/m2 (J), every 21 days if there was haematological recovery.
Results: Seventy out of ninety‐five (74%) patients completed seven or more courses and were evaluable for toxicity. Of these 70 patients, 33% had more than three episodes of fever and sepsis, 35% required more than five blood or platelet transfusions, 36% had grade 2 or more gastrointestinal toxicity and 9% had neurotoxicity. There was a median reduction in GFR of 32 ml/min/1.73 m2 (−46 to 134) and there was one toxic death.
Conclusions: OPEC/OJEC is a well‐tolerated therapy for stage 4 neuroblastoma over 1 year of age.
