Abstract

Testicular tumors in children have two peaks with different types of tumors; in the first 4 years of life a third to half are benign with increased risk of malignancy during puberty. The pathology of testicular tumors between these peaks, at the age of 5-12 years, is not known. We hypothesized that because of the low level of testosterone at this time, the incidence of malignant tumors is very low. To compare malignancy risk of primary testicular tumors in children in the prepubertal period (5-12 years) compared with younger (0-4 years) and pubertal (13-18 years) children. We retrospectively (2002-2016) identified patients <18 years with surgery for primary testicular tumor. Patients with testicular tumor risk were excluded. Ultrasound studies were reviewed for contralateral testis volume, tumor morphology, and tumor maximal diameter, for three age groups: 0-4, 5-12, and 13-18 years. The Freeman-Halton extension of the Fisher exact probability test was adopted for categorical outcomes, and one-way ANOVA for continuous outcomes. Fifty-two patients (mean age 11.0 years, range 6 days-18 years) were identified. Malignant tumor prevalence significantly differed (p < 0.01) among age groups (Fig).: 0-4 (72.7%, 8/11), 5-12 (0%, 0/16), ...Continue Reading
