[Study of twenty-three cases of pediatric testicular tumors]

Twenty-three cases of testicular tumor (10; malignant, 13; benign) in childhood are reported. The age at diagnosis was between 3 months old and 8 years old. Twelve patients visited the clinic within a month of first appearance of symptoms. All but one patient received high orchiectomy. One patient had resection of tumor because of its benign property. Eight of the 10 patients with malignancies received 30-50Gy of retroperitoneal radiation, including one patient (stage IIa) with retroperitoneal lymph node dissection. Two patients (stage I and IIa) with post-operative metastasis in lungs, brain and mediastinal lymph nodes were treated with chemotherapy repeatedly, but they died. Our latest therapy is; 1) high orchiectomy recommended for benign and stage I malignant testicular tumors in childhood, 2) retroperitoneal radiation and/or lymph node dissection limited for patients with stage II malignancy, and 3) Systemic chemotherapy for stage III malignant tumors. At least three years of follow up would be needed. Those who received radiation or chemotherapy should be followed longer.
