Abstract
Decreased Ecadherin expression was observed in 353 patients 521 and was associated with advanced pathological stage P 0001 higher grade P 0001 lymph node metastasis P = 0006 lymphovascular invasion P 0001 concomitant carcinoma in situ P 0001 multifocality P = 0004 tumor necrosis P = 0020 and sessile architecture P 0001 Within a median followup of 30 months interquartile range 15–57 171 patients 254 experienced disease recurrence and 150 219 died from UTUC In univariable analyses decreased Ecadherin expression was significantly associated with worse recurrencefree survival P 0001 and cancerspecific survival CSS P = 0006 however in multivariable analyses it was not P = 074 and 084 respectively The lack of independent prognostic value of Ecadherin remained true in all subgroup analysesIn UTUC patients treated with RNU decreased Ecadherin expression is associated with features of biologically and clinically aggressive disease and worse outcome in univariable but not multivariable analyses If Ecadherin’s association with factors of advanced disease is confirmed on UTUC biopsy specimens it could be used to help in the clinical decisionmaking regarding kidneysparing approaches and/or neoadjuvant chemotherapy
