ABSTRACT

Objectives: To determine if there is an association between the neutrophil to lymphocyte ratio (NLR) and prognosis in patients with epithelial ovarian cancer (EOC) diagnosed and treated in a Spanish population. Material and methods: Retrospective cohort of patients with epithelial ovarian cancer who had neutrophil and lymphocyte values in complete blood count before the histopathological diagnosis and survival of at least three months, in an intermediate complexity hospital. Convenience sampling. Measured variables included age, menopausal stage, parity, International Federation of Gynecology and Obstetrics (FIGO) stage, treatment type, residual tumor, lymph node involvement, presence of ascites, cytology, histologic type, differentiation grade, and CA-125 values. Additionally, outcomes, overall survival, disease/progression-free survival were also measured. Bivariate inferential and Cox regression analyses were performed. Results: Out of 78 candidates, 60 women with EOC were included. Of them, 24 (40%) had a low NLR (≤ 2,9) while 36 (60%) had a high NLR (> 2,9). An association was found between high NLR levels and suboptimal cytoreductive surgery. High NLR ratios were associated with lower overall survival (Hazard ratio (HR): 4.1; 95% CI: 1.4-11.8) and lower 5-year disease-free survival (HR: 2.6; 95% CI: 1.2-5.7). Conclusions: A plasma neutrophil to lymphocyte ratio of more than 2.9 was associated with poor prognosis in patients with epithelial ovarian cancer in our setting. There is a need to establish the optimal cut-off point and conduct prospective studies with larger patient numbers in order to support this information.


Objetivos: evaluar si hay asociación entre los valores del cociente plasmático neutrófilos/ linfocitos (NLR) y el pronóstico en pacientes con cáncer epitelial de ovario (CEO) diagnosticadas y tratadas en una población española. Materiales y métodos: cohorte retrospectiva de pacientes con cáncer epitelial de ovario que tuvieran un recuento de neutrófilos y linfocitos en hemograma previo al diagnóstico histopatológico en un hospital de nivel medio de complejidad y posterior sobrevida de, al menos, 3 meses. Muestreo por conveniencia. Se midieron: edad, estado menopáusico, paridad, estadio Federación International de Ginecología y Obstetricia (FIGO), tipo de tratamiento, tumor residual, afectación ganglionar, presencia de ascitis, citología, tipo histológico, grado de diferenciación y cifras de CA-125; como desenlaces, sobrevida global y sobrevida libre de enfermedad o progresión. Análisis inferencial bivariado y por regresión de Cox. Resultados: de 78 candidatas, ingresaron 60 mujeres con CEO. De ellas, 24 (40%) presentaron un NLR bajo (≤ 2,9) y 36 (60 %) elevado (> 2,9). Se encontró asociación entre los niveles altos de NLR y cirugía citoreductora subóptima. Los niveles altos de NLR se asociaron a menor sobrevida global (Hazard ratio (HR): 4,1; IC 95%: 1,4-11,8) y menor sobrevida libre de enfermedad a los 5 años (HR:2,6; IC 95 %: 1,2-5,7). Conclusiones: un cociente plasmático neutrófilos/linfocitos mayor de 2,9 se asoció a un mal pronóstico en pacientes con cáncer epitelial de ovario en nuestro medio. Se necesita determinar el punto de corte óptimo y realizar estudios prospectivos con mayor número de pacientes que avalen esta información.
