RESUMEN
Chemotherapy-induced peripheral neuropathy (CIPN) and associated pain are prevalent adverse effects of pediatric cancer treatment, significantly affecting the patient's quality of life. Their impact and risk factors have yet to be assessed in our country. This study aimed to assess the prevalence and clinical characteristics of CIPN, as well as to explore associations with patient- and treatment-related variables, within a cohort of Argentinean pediatric oncology patients. Sixty-six patients diagnosed with malignant hematopoietic tumors and receiving the neurotoxic agent vincristine were included in this observational study. Variables analyzed included age, gender, anthropometric measurements, tumor type, chemotherapy treatment, development of pain and other symptoms, severity, and analgesic treatment. The study population consisted of 39 boys and 27 girls. Most patients received two or three neurotoxic drugs. Symptoms consistent with CIPN were identified in 15 children, reflecting a prevalence of 23%. The main symptom was pain in the lower limbs, with some patients reporting jaw or generalized body pain. Pain was categorized as moderate or severe in 60% and 27% of cases, respectively. NSAIDs, anticonvulsants, and/or opioids were prescribed. Among the patient- and treatment-related variables analyzed as potential risk factors, the use of vincristine in conjunction with cytarabine and the administration of a higher number of neurotoxic drugs demonstrated significant association with the development of CIPN. CONCLUSIONS: Combination therapy stands out as a risk factor for clinical CIPN. The high prevalence of moderate/severe pain underscores the importance of close vigilance given its potential to compromise the patient's overall well-being. WHAT IS KNOWN: ⢠Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent adverse effect and dose-limiting factor in pediatric cancer treatment. ⢠Prevalence varies among regions and risk factors are still under study. WHAT IS NEW: ⢠Prevalence of symptomatic CIPN is 23% among pediatric patients undergoing treatment for hematopoietic tumors in a referral hospital in Argentina. Most patients report moderate or severe pain. ⢠Combining vincristine with cytarabine and using a higher number of neurotoxic drugs in combination therapies exhibit significant association with the development of CIPN-related symptoms.
RESUMEN
Introducción: El dolor se define como una experiencia sensorial y emocional desagradable, relacionada con daño tisular actual o potencial. Según su mecanismo fisiopatológico, se clasifica en dolor nociceptivo, neuropático y mixto. Cuando su intensidad es de moderada a grave, se debe administrar un opioide potente, y la morfina es el fármaco de elección. Si resulta ineficaz o aparecen efectos adversos intolerables, se recomienda la rotación de opioide. Nuestro objetivo fue describir el tratamiento farmacológico del dolor mixto en los pacientes asistidos por el equipo de Cuidados Paliativos del Hospital General de Niños Pedro de Elizalde entre agosto de 2011 y septiembre de 2015. Se incluyeron 72 pacientes, con edad media de 10,1 años y la enfermedad de base más frecuente fue patología oncológica. El opioide de inicio fue morfina en 57 casos; 48 recibieron fármacos adyuvantes. La rotación de opioides ocurrió en la mitad de los casos y la más frecuente fue de morfina a metadona.
Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Depending on its pathophysiological mechanism, it may be classified into nociceptive, neuropathic, and mixed pain. If pain is moderate to severe, a strong opioid should be administered and, when this is the case, morphine is the drug of choice. If morphine is ineffective or causes intolerable adverse effects, opioid rotation is recommended. Our objective was to describe the drug management for mixed pain used in patients assisted by the Palliative Care team of Hospital General de Niños Pedro de Elizalde between August 2011 and September 2015. A total of 72 patients were included. Their mean age was 10.1 years, and the most common underlying disease was cancer. The initial opioid was morphine in 57 cases; 48 patients received adjuvant drugs. Opioid rotation was indicated in half of cases, and the most common switch was from morphine to methadone.
