[Active surveillance for testicular tumors: adherence and safety.]

INTRODUCTION The active surveillance (AS) of testicular tumors (seminoma and non-seminoma) is the most frequent management option in the stage I disease. Relapses generally occurred within the first 3 years and 4cm and the rete testis invasion in the ST, the linfovascular invasion and the percentage>40% of embrionary carcinoma in the NST. Adherence to the AS protocol was evaluated, focusing on those patients who lost it and what time it occurred. RESULTS A total of 64 patients were included. The median follow-up was 36 months (IC 21-48 months). 12 patients lost the follow-up during the protocol with a median follow-up of 27.5 months (IC 16-30 months). A 21.8% of patients entered in the AS protocol with some associated risk factor. Adherence follow-up was successful in the first year (96.8%) and decreased over time (92.2% at 24 months and 86.3% at 36 months). CONCLUSION We presented an important adherence to the AS protocol in patients with clinical stage I testicular cancer and in our series there no recurrences after 36 months of follow-up.
