Abstract
We studied the records of 342 patients with papillary thyroid carcinoma out of a total of 728 thyroid cancer patients treated at the Medical School of Hannover (MHH) from 1972 through 1992. The comprehensive data-abstracting forms were designed, and the acquired information was coded, stored, maintained, and evaluated by the Clinical Cancer Registry of the MHH. A total of 160 patients (46.8%) initially had lymph node metastases (N1 status). The N status significantly influenced recurrence (pp45 years, pppppppppp45 ans (pppp45 ans (ppppp≪0,0001) y la sobrevida (p≪0,0001). Al excluir otros factores adicionales de riesgo identificados mediante análisis univariable y multivariable, tales como edad (mayores de 45 años, p≪0,001), invasión tumoral (tumor T4, p≪0.005) y metástasis distantes (M1, p≪0,001), las metástasis ganglionares se mantuvieron como un marcador independiente y altamente significativo de comportamiento agresivo del cáncer tiroideo. El estado N1 no tuvo influencia sobre la sobrevida de pacientes con tumor T4 sino con el estado T1–T3 (p≪0,001). La influencia del estado N1 se mantuvo significativa en los pacientes de mayor edad (p≪0,001) y los menores de 45 años (pp≪0,005, T1–T3) y la recidiva (p≪0,00001, T1–T3), especialmente en pacientes con tumor T1–T3. En conclusión, las metástasis ganglionares con incidencia significativa en la edad joven y en el sexo masculino exhibieron una influencia sustancial en lo pertinente a sobrevida y recidíva, especialmente en los pacientes con tumor T1–T3. La disección sistemática de tipo compartimental de las metástasis ganglionares resulta en mejor tasa de sobrevida y menor tasa de recidiva.Keywords
