The role of primary surgery and external beam radiation therapy in the management of non-metastatic ductal prostate cancer: 20-year outcomes from a single institution experience

View Poster

INTRODUCTION

Ductal carcinoma of the prostate (DAC) is a rare histological subtype of prostate cancer (PC). Although it is reported to be an aggressive tumor, often with locally advanced and/or metastatic disease at presentation, the available literature still lacks of reports on treatment recommendations since there are still controversies about the optimal therapeutic approach. We present our 20-year outcome of multidisciplinary management of non-metastatic DAC (nmDAC).

METHODS

A retrospective analysis of our Institutional Urology-Radiation Oncology database was performed. Patients (pts) with nmDAC undergoing radical treatment were included. All these pts were discussed at our multidisciplinary Oncology board in order to highly personalize the treatment. The cohort was divided into three groups according to received treatment: group A surgery (either radical prostatectomy or cystectomy), group B surgery and post-operative radiation therapy (RT, either adjuvant or salvage) and group C RT alone. Kaplan-Meier method was used to estimate survival outcome, after adjusting for predictive variable (age, comorbidities, pathological stage, histology). Statistical analysis was performed using SPSSv20, considering statistically significant p value
