35例小儿睾丸肿瘤中睾丸卵黄囊瘤16例(45.7％),畸胎瘤12例(34.3％)。分析表明,以睾丸无 痛性肿块为主要症状(91％),其次为鞘膜积水(20％)等。血清AFP是诊断小儿卵黄囊瘤的重要肿瘤标记物。33例采用经腹股沟睾丸切除术。4例睾丸卵黄囊瘤接受淋巴清扫术。16例卵黄囊瘤病例术后化疗1年,2例死于肿瘤转移。结果表明,大多数小儿睾丸卵黄囊瘤诊断时为Ⅰ期,经腹股沟高位精索睾丸切除可望治愈。对2岁以上病例应化疗1年,以提高治愈率。
In 35 pediatric testicular tumors, 16 (45.7%) cases had testicular yolk sac tumor and 12 (34.3%) had teratoma. Analysis shows that painless testicular mass as the main symptom (91%), followed by hydrocephalus (20%) and so on. Serum AFP is an important tumor marker for the diagnosis of yolk sac tumors in children. 33 cases of transvaginal orchiectomy. Four cases of testicular yolk sac tumor underwent lymphadenectomy. Sixteen patients with yolk tumor were treated with chemotherapy for one year and two died of tumor metastasis. The results showed that most of the pediatric testicular yolk sac tumor is stage Ⅰ, the groin high spermatic cord orchiectomy is expected to be cured. For patients over 2 years of chemotherapy should be 1 year, in order to improve the cure rate.
