[Testicular tumours in children: Indications for testis-sparing surgery].

INTRODUCTION AND OBJECTIVES Although standard surgical treatment of a testicular tumour is orchiectomy, use can be made of testis-sparing surgery in selected cases, based on tumour markers, tumour size, and histopathological findings. Our objective is to become acquainted with the indications of testis-sparing surgery as a treatment for the incidental finding of a palpable and non-palpable testicular mass. MATERIAL AND METHODS A retrospective study was conducted on 22 patients younger than 18 years diagnosed with a testicular tumour between 2000 and 2014. An assessment was made of the condition, the history, ultrasound, histopathology, tumour markers (BHCG, AFP), therapeutic approach, and outcome. RESULTS Of the 22 patients (10 prepubertal age) studied, 82% had palpable mass, and 18% were incidental findings. Two had cryptorchidism. The BHCG was increased in 27% and AFP in 45% of cases. There were 18 tumorectomies and 4 orchiectomies performed. The histopathology found 72% germ cell, 14 orchiectomy, and 2 tumorectomies (2 teratomas), with 27% non-germ cell tumours in 4 orchiectomies and 2 tumorectomies (2 cells of Leydig). Six patients received post-surgical chemotherapy (mixed tumours). The median tumour size was 1 (0.4-1.5) cm in tumorectomies, and 2.5 (0.5-14) cm in orchiectomies. The mean follow-up was 5 (1-15) years. One patient died due to metastatic disease. There was no local recurrence in the follow up of the tumorectomies. CONCLUSIONS A change in the trend of our therapeutic approach is demonstrated. We propose that testis-sparing surgery is indicated in prepubertal patients who meet the benignity criteria of the testicular mass (small size and negative tumour markers).
