Of the 5 patients with available follow-up, 3 were free of disease at 1, 5, and 8 years after orchiectomy (2 necrotic seminomas and 1 germ cell tumor, unclassified). One patient with yolk sac tumor (age 63 y) developed widespread metastases after 15 months and died of disease.

随访了5例患者，其中3例于睾丸肿瘤切除术后1、5和8年任健在且无复发（2例为坏死的精原细胞瘤、1例为未分类的生殖细胞肿瘤）。1例为内胚窦瘤（63岁），15个月后广泛转移，并死于本病。
