Introduction: Chemotherapy-induced peripheral neuropathy is a common adverse reaction in a variety of medications frequently used for a great number of cancer treatments. This condition consists of mainly sensory-type symptoms, motor components and autonomic changes. Reported prevalence ranges from 30-68%, after the completion of chemotherapy in non-Latin American people with different populations and socioeconomic levels.
Aim: To determine the prevalence of chemotherapy-induced peripheral neuropathy in a Colombian population.
Patients and methods: A real-world evidence cross-sectional retrospective study was performed in all patients from oncological clinical centers in Colombia, which received pharmacological therapy for any cancer between January 2015 and December 2016, with taxanes (paclitaxel, docetaxel), alkylators (oxaliplatin), proteasome inhibitors (bortezomib), and epothilone B analogs (ixabepilone).
Results: A total of 1,551 patients in four cities were included, and 11,280 doses were applied; predominantly females (n = 1,094; 70.5%), with a mean age of 57 ± 13 years old. Paclitaxel was the most commonly prescribed drug (n = 788; 50.8%). Chemotherapy-induced peripheral neuropathy was developed in 48.9% of paclitaxel, 58.5% of oxaliplatin, 50.5% of docetaxel, 43.7% of bortezomib and 95.2% of ixabepilone patients. Thirty-three patients were treated with two of these medications simultaneously.
Conclusions: Chemotherapy-induced peripheral neuropathy is a frequent adverse reaction to daily cancer therapy in Colombian patients managed with taxanes, alkylators, proteasome inhibitors, and epothilone B analogs. Hence, it is necessary to establish more successful diagnostic methods and incorporate validated scales in the routine evaluation of all patients receiving these medications in our environment.
Title: Prevalencia de neuropatia periferica asociada a quimioterapia en cuatro centros oncologicos de Colombia.
Introduccion. La neuropatia periferica inducida por quimioterapia es una reaccion comun a una variedad de medicamentos usados en el tratamiento del cancer, que consiste principalmente en sintomas sensitivos, con componentes motores y cambios autonomicos. La prevalencia es del 30-68% despues de terminar la quimioterapia en paises no latinoamericanos. Objetivo. Determinar la prevalencia de la neuropatia periferica inducida por quimioterapia en la poblacion colombiana. Pacientes y metodos. Estudio retrospectivo con evidencia del mundo real en la totalidad de pacientes atendidos en cuatro centros oncologicos de Colombia, quienes recibieron terapia farmacologica para algun tipo de cancer entre enero de 2015 y diciembre de 2016 con taxanos (paclitaxel, docetaxel), agentes alquilantes (oxaliplatino), inhibidores de proteasoma (bortezomib) y analogos de epotilona B (ixabepilona). Resultados. Se siguio a un total de 1.551 pacientes en cuatro ciudades a quienes se les aplicaron 11.280 dosis, con predominio femenino (n = 1.094; 70,5%) y una edad media de 57 ± 13 años. El paclitaxel fue el farmaco mas prescrito (n = 788; 50,8%). La neuropatia inducida por quimioterapia se presento en el 48,9% de los pacientes con paclitaxel, el 58,5% de los pacientes con oxaliplatino, el 50,5% de los pacientes con docetaxel, el 43,7% de los pacientes con bortezomib y el 95,2% de los pacientes con ixabepilona. Se trato a 33 pacientes con dos de estos medicamentos simultaneamente. Conclusiones. La neuropatia periferica inducida por quimioterapia es una reaccion adversa frecuente en pacientes con cancer en Colombia tratados con taxanos, alquilantes, inhibidores de proteasoma e ixabepilona. Es necesario establecer metodos diagnosticos efectivos e incorporar escalas validadas en la evaluacion rutinaria de los pacientes que reciben estas medicaciones.
