ABSTRACT

RESUMEN Objetivo: determinar la prevalencia del compro miso ganglionar de pacientes con cáncer de endometrio y hacer una exploración de los factores asociados a la invasión ganglionar. Materiales y métodos: estudio de prevalencia con análisis exploratorio. Se incluyeron pacientes con cáncer de endometrio llevadas a histerectomía abdominal total más salpingooforectomía bilateral y linfadenectomía pélvica, con o sin linfadenectomía paraaórtica en siete centros de oncología de Colombia, en el periodo 2009-2016. Se excluyeron pacientes con radioterapia o quimioterapia previa, diagnóstico histológico de tumores neuroendocrinos, carcinosarcomas, tumores sincrónicos o metacrónicos. Muestreo no probabilístico. Tamaño muestral n = 290. Variables medidas: sociodemográficas, clínicas e histopatológicas y compromiso ganglionar pélvico o paraaórtico. Se presenta la prevalencia de periodo; el análisis exploratorio se realizó por medio de odds ratio (OR) crudo y el ajustado mediante un modelo multivariado (regresión logística no condicional). Resultados: se obtuvieron 467 casos de los cuales se excluyeron 163 por no presentar la totalidad de las variables, se estudiaron 304 pacientes. La prevalencia del compromiso ganglionar fue del 15,8 % (48/304). Los factores asociados al compromiso ganglionar en el análisis crudo y ajustado fueron la invasión linfovascular (OR ajustado = 9,32; IC 95 %: 4,27-21,15) e invasión miometrial (OR ajustado = 3.95; IC 95 %: 1,29-14,98). Conclusión: el 15 % de las pacientes sometidas a linfadenectomía tienen compromiso ganglionar. Se deben evaluar alternativas diagnósticas menos invasivas que la cirugía radical para establecer la invasión ganglionar.


ABSTRACT Objective: To determine the prevalence of lymph node involvement in patients with endometrial cancer and to explore factors associated with lymph node invasion. Materials and methods: Prevalence study with exploratory analysis. The study included patients with endometrial cancer who underwent total abdominal hysterectomy plus bilateral salpyingooophorectomy and pelvic lymphadenectomy with or without para-aortic lymphadenectomy in seven oncology centers in Colombia between 2009 and 2016. Patients who had received prior radiotherapy or chemotherapy, with a histological diagnosis of neuroendocrine tumors, carcinosarcomas or synchronous or metachronous lesions were excluded. Non-probabilistic sampling. Sample size n=290. Measured variables: sociodemographic, clinical and histopathological, and pelvic or para-aortic lymph node involvement. The prevalence for the period is presented. The exploratory analysis was conducted using crude odds ratio (OR) and adjusted OR by means of a multivariate model (unconditional logistic regression). Results: Overall, 467 cases were retrieved. Of them, 163 were excluded because of non-availability of all the variables. In total, 304 patients were studied. The prevalence of lymph node involvement was 15.8 % (48/304). In the crude and adjusted analysis, factors associated with lymph node involvement were lymphovascular invasion (adjusted OR: 9.32; 95 % CI 4.27-21.15) and myometrial invasion (adjusted OR: 3.95; 95 % CI 1.29-14.98). Conclusion: Of the patients undergoing lymphadenectomy, 15 % have lymph node involvement. Less invasive diagnostic options than radical surgery to ascertain lymph node invasion should be assessed.
