Platinum compounds are widely used in the treatment of pediatric tumors such as neuroblastoma, germ-cell tumors, osteosarcoma, retinoblastoma, hepatoblastoma, brain tumors (low-grade gliomas and medulloblastoma/PNET), and relapsed and refractory lymphomas. The three major platinum compounds (cisplatin, carboplatin, and oxaliplatin) have a similar pharmacokinetics profile and mechanism of action, but the differences in their chemical structure are responsible for their different antitumor activity and toxicity. In this review, we have described the main characteristics of cisplatin, carboplatin, and oxaliplatin, focusing on their toxic effects and possible strategies to prevent them to improve the clinical outcomes in pediatric cancer patients. The underlying mechanism of each platinum-related toxicity is shown together with the clinical manifestations. Furthermore, possible preventive strategies are suggested to reduce the negative impact of platinum compounds on the quality of life of children with cancer. Cisplatin seems to be mostly ototoxic and nephrotoxic, carboplatin mainly produces myelosuppression, whereas oxaliplatin induces predominantly peripheral sensory neurotoxicity. In contrast, nausea and vomiting can be linked to all platinum compounds, although cisplatin exerts the strongest emetic effect. A correct knowledge of pharmacokinetics and toxicological profile of platinum compounds may aid physicians prevent their toxicity on auditory, nervous, renal, and bone marrow function, improving the quality of life of pediatric cancer patients.
Hemophagocytic lymphohistiocytosis is a potentially fatal disorder resulting from excessive activation and non-malignant proliferation of T lymphocytes and macrophages. Neoplasms, autoimmune disorders and systemic infections can cause secondary hemophagocytic syndrome. The association of hemophagocytic syndrome and visceral leishmaniasis is rarely found in childhood. We report a case of an infant affected by hemophagocytic lymphohistiocytosis secondary to visceral leishamniasis and describe all cases of hemophagocytic syndrome associated with visceral leishamniasis in childhood reported in literature, focusing on clinical manifestation, diagnosis and treatment.
With the increasing use of cancer chemotherapy agents, hypersensitivity reactions to antineoplastic drugs are commonly encountered. Clinicians must not underestimate the potential risk and occurrence of HSRs in the pediatric population. Knowledge of the different presentations of these reactions can help to develop strategies for the prevention and the management of HSRs in order to ensure treatment outcome, to improve the quality of patient care and to reduce healthcare costs.
Appropriate hydration remains the main fundamental strategy for reducing the risk of cisplatin-induced nephrotoxicity. In conventional treatment regimens employing doses of cisplatin of less than 100 mg/m(2) in patients with normal renal function, pre- and post-hydration (3 l/m(2) at least 12 h pre-cisplatin and 24 h post-cisplatin) alone should be routinely used. In higher doses, pre- and post-hydration plus mannitol should be considered in order to ensure a valid diuresis.
Platinum’ derivates are antineoplastic agents widely adopted for their efficacy for the treatment of many pediatric cancers. The use of cisplatin has positively influenced the results of the cure of different childhood malignancies. However, cisplatin-based treatments are limited by the risk of severe and progressive toxicities, such as oto- or nephrotoxicity, that can be more serious in very young children expecially when high cumulative doses and/or radiotherapy is administered. A correct knowledge of the cisplatin’ pharmacological features might be of interest for clinicians in order to manage its potential toxicities. Based on the positive trend in the cure of children with cancer, it is crucial that all children receiving cisplatin-based chemotherapy have and appropriate and long-term follow-up to improve their quality of life.
In this brief report we have described eight children affected by optic pathway/hypothalamus gliomas and treated with carboplatin and/or cisplatin, which developed a derangement of sodium and water metabolism, due to diabetes insipidus (DI) or to syndrome of inappropriate antidiuretic hormone secretion (SIADH) after surgical resection. In four out of these eight patients the treatment with platinum compounds produced prolonged haematological toxicity and in five out of them it caused neurosensorial bilateral hypoacusia. In addition cisplatin worsened electrolytes disturbances. Hence children with DI or SIADH should be carefully monitored before, during and after the treatment with platinum compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
