Abstract

PURPOSE: We assessed the feasibility of testis-sparing surgery in children with testicular tumors.
MATERIALS AND METHODS
Twenty-five pediatric patients who had a testicular tumor were enrolled for retrospective analysis. Testis-sparing surgery was planned in the cases with clinical features that preoperatively suggested the tumors to be benign, which was later determined intraoperatively by frozen section examination. The preoperative-fetoprotein (AFP) and transscrotal ultrasound (US) were evaluated along with the final pathology. We reviewed the immediate and late surgical complications, as well as the tumor recurrence after surgery.
RESULTS
Teratoma, epidermoid cyst, yolk sac tumor, and Leydig cell tumor accounted for finding in 40%, 32%, 24%, and 4% of the patients, respectively. Based on the preoperative US, 18 patients had benign-looking tumors. According to the age-matched AFP references, 17 patients showed normal ranges preoperatively. Out of 14 patients, whose US and AFP level suggested the tumors to be benign, 10 (71.4%) were eligible for testis- sparing surgery on retrospective review. Testis-sparing surgery was performed in 5 patients, who showed the same pathology in frozen sections (3 epidermoid cysts, 2 teratomas). None of the 5 patients exhibited perioperative complications, and no recurrence or atrophy was observed at a mean follow-up of 39.8 months.
CONCLUSIONS
Out of 14 patients, whose US and AFP analyses were available, 10 (71.4%) were eligible for testis-sparing surgery. Testis-sparing surgery was done in five out of the 10 patients without any complication or recurrence. Testis-sparing surgery is a feasible option in children with testicular tumors if the AFP level is within a normal range and the US suggests benign characteristics.
