Factores personales e histopatolÓgicos como variables pronÓsticas en tumores uroteliales superiores sometidos a cirugía

OBJECTIVE: To analyze the influence of personal and histopathological factors as prognostic variables in the evolution of upper urothelial tumors submitted to radical surgery. METHODS: Multifactorial retrospective study of a series of 61 patients submitted to radical surgery for upper urinary tract transitional cell tumors. Patient habits and histopathological factors are analyzed. The statistical significance of the different factors was analyzed using the Pearson chi-square test for the qualitative variables, with analysis of the residuals and Kaplan-Meier survival curves and statistical validation with the Mantel Cox test. The level of significance was p < 0.05. RESULTS: A statistically significant correlation was found for tumor-related death and pathological stage, positive lymphadenectomy and positive lymphadenopathy on the CT (p < 0.05). The presence or absence of a history of smoking was not available for all patients and was therefore not evaluable. The most frequent reason for consultation was hematuria (39%). Tumor growth was mostly of the papillary type (79%), localization was mostly in the renal pelvis (30%) and the most frequent procedure was nephroureterectomy without endoscopic detachment (60%). CONCLUSIONS: The pathological stage and a positive lymphadenectomy or the presence of positive lymphadenopathies on the CT were found to be prognostic factors in urothelial tumors of the upper urinary tract.
