Abstract

Introduction: Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent and severe side effect of cancer treatment. Its prevalence in Argentina, and potential risk factors, remain unknown.

Materials and methods: A cohort of 56 patients with colorectal carcinoma treated with oxaliplatin was studied. Clinical records were retrospectively analyzed to extract relevant data.

Results: The study included 56 patients, 30 males (54%) and 26 females (46%). The therapeutic regimens used were FOLFOX (45%) and XELOX (55%). A total of 41 patients developed symptoms consistent with CIPN, with an overall prevalence of 73%. Prevalence was higher in women (88%) compared to men (60%), with an association found between female sex and the development of neurotoxicity (p=0.01). No significant associations were found with other factors such as age, overweight, tumor stage, chemotherapy regimen, or cumulative dose (p>0.05 in all cases). In the entire cohort, sex-related differences were only detected in the prevalence of overweight, being higher in men (p=0.0167). Among CIPN patients, sex-related differences were also found: men had a higher prevalence of overweight (p=0.0427) and received higher cumulative doses (p=0.0368), while XELOX was more frequently used in women (p=0.0495). In the subgroup of patients treated with XELOX, a higher prevalence of CIPN in women was again confirmed (p=0.0278).

Discussion: Our results highlight the impact of sex on the prevalence and clinical presentation of this adverse effect of cancer treatment.

Introducción: La neuropatía periférica inducida por quimioterapia (NPIQ) es un efecto adverso frecuente y severo del tratamiento antitumoral. Se desconoce la prevalencia en Argentina y los posibles factores de riesgo. Materiales y métodos: Se estudió una cohorte de 56 pacientes con carcinoma colorrectal tratados con oxaliplatino. Los registros clínicos fueron analizados retrospectivamente, permitiendo extraer los datos de interés. Resultados: El estudio incluyó 56 pacientes, 30 hombres (54%) y 26 mujeres (46%). Los esquemas terapéuticos utilizados incluyeron FOLFOX (45%) y XELOX (55%). Un total de 41 pacientes desarrollaron síntomas compatibles con NPIQ, siendo la prevalencia general 73%. La prevalencia fue mayor en mujeres (88%) que en hombres (60%), identificándose asociación entre el sexo femenino y el desarrollo de neurotoxicidad (p=0.01). No se encontraron asociaciones significativas con otros factores como edad, sobrepeso, estadio tumoral, esquema quimioterápico y dosis acumulada (p>0.05 en todos los casos). En la cohorte completa solo se detectaron diferencias asociadas al sexo en la prevalencia de sobrepeso, siendo mayor en hombres (p=0.0167). En el subgrupo de pacientes con NPIQ también se detectaron diferencias asociadas al sexo: los hombres presentaron mayor prevalencia de sobrepeso (p=0.0427) y recibieron dosis acumuladas más altas (p=0.0368), mientras que el esquema XELOX se utilizó más frecuentemente en mujeres (p=0.0495). En el subgrupo tratado con XELOX, se confirmó nuevamente una mayor prevalencia de NPIQ en mujeres (p=0.0278). Discusión: Nuestros resultados destacan el impacto del sexo en la prevalencia y la presentación clínica de este efecto adverso del tratamiento antitumoral.
