Median age was 5 years.Cancer type: neuroblastoma 51%, malignant germ cell tumour 13%, medulloblastoma 11%, osteosarcoma 9%, nasopharyngeal undifferentiated carcinoma 7%, hepatoblastoma 5%, and 2% each for metastatic rhabdomyosarcoma and sacrococcygeal teratoma.Only sacrococcygeal teratoma and metastatic rhabdomyosarcoma, which showed 127 managements in front of the appeared side effects, in 88% of cases the drugs were administered to correct adverse effects, in 5.5% the cures were shifted, in 4.7% the cures were stopped and in 1.8% the dosages were reduced.Based on the cost of the drugs administered to treat and correct the side effects of these two types of cancer, we noted a total of €4500 in addition to the cost of chemotherapy.Conclusion and relevance According to our results, the cost of management of secondary events related to cytotoxic drugs is considerable, so it is necessary to focus on other studies to evaluate the pharmacoeconomic impact of the indirect costs of these diseases.Conflict of interest No conflict of interest
