Testicular tumors in the pediatric population are fundamentally distinct from their adult counterparts. We reviewed a contemporary single series from a large pediatric health science center. We also examined our experience with testis conserving surgery and then used it to develop a preoperative management algorithm.
A retrospective review was performed of all testicular tumors at a single institution from 1984 to 2002. Data were compiled using the American Academy of Pediatrics testis tumor registry data collection form. We further examined partial orchiectomies for indications and outcomes with respect to cancer control and testicular viability.
A total of 51 primary testicular lesions were identified. Patient age was prenatal to 16 years with a scrotal mass the most common presentation (81%). Mature teratoma, rhabdomyosarcoma, epidermoid cyst, yolk sac and germ cell tumors accounted for 43%, 26%, 10%, 8% and 6% of cases, respectively. This distribution was markedly different from the last reported American Academy of Pediatrics data base. Organ preserving surgery was planned and achieved in 13 cases. All surgeries were successful with respect to cancer control and testicular preservation.
We believe that the higher incidence of teratoma is more representative of this population and yolk sac tumor is a minority diagnosis. The single institution review eliminates the interinstitutional referral heterogeneity that may have skewed larger data bases. Furthermore, the concept of testicular preserving surgery becomes an attractive option since we present its safety and efficacy. The management algorithm should facilitate the preoperative decision to perform less radical surgery and help preserve testicular tissue.
儿科人群的睾丸肿瘤与成人的睾丸肿瘤有根本区别。我们回顾了一家大型儿科健康科学中心的当代单一病例系列。我们还研究了我们在睾丸保留手术方面的经验,并用它来制定术前管理算法。
对1984年至2002年单一机构的所有睾丸肿瘤进行回顾性研究。使用美国儿科学会睾丸肿瘤登记数据收集表汇编数据。我们进一步检查了部分睾丸切除术的适应症以及癌症控制和睾丸存活方面的结果。
共识别出51例原发性睾丸病变。患者年龄从产前到16岁,最常见的表现是阴囊肿块(81%)。成熟畸胎瘤、横纹肌肉瘤、表皮样囊肿、卵黄囊瘤和生殖细胞肿瘤分别占病例的43%、26%、10%、8%和6%。这种分布与上次报告的美国儿科学会数据库明显不同。计划并成功实施了13例保留器官手术。所有手术在癌症控制和睾丸保留方面均获成功。
我们认为畸胎瘤的较高发病率更能代表该人群,而卵黄囊瘤是少数诊断。单一机构的回顾消除了可能使更大数据库产生偏差的机构间转诊异质性。此外,由于我们展示了睾丸保留手术的安全性和有效性,该手术概念成为一个有吸引力的选择。管理算法应有助于术前决定进行不太激进的手术,并有助于保留睾丸组织。
