双侧睾丸生殖细胞肿瘤的发生率约为睾丸肿瘤的1～5.7％。因为治疗方法特别是化疗的改进,恶性睾丸肿瘤的预后已有改善,已发生转移者亦可能长期存活。因此,对侧睾丸肿瘤问题已日益重要。 1969～1985年间瑞士和奥地利两医学院共诊治412例睾丸生殖细胞肿瘤,20例(4.3％)双侧患病,其中1例同时发病,19例相继发病,间隔时间2月～32年(平均73月)。精原细胞瘤一般给予放疗;5例无腹膜后淋巴转移的非精原细胞肿瘤,因10年前放疗效果好也接受放疗。非精原细胞瘤根据分期,一般作腹膜后淋巴清扫术和/或化疗,第二
The incidence of bilateral testicular germ cell tumors is approximately 1 to 5.7% of testicular tumors. Because of the improvement of treatment methods, especially chemotherapy, the prognosis of malignant testicular cancer has been improved, and those who have metastasized may also have long-term survival. Therefore, the problem of contralateral testicular tumors has become increasingly important. Between 1969 and 1985, 412 cases of testicular germ cell tumors were diagnosed and treated by the two medical schools in Switzerland and Austria. 20 cases (4.3%) were bilaterally ill, of which 1 case was onset at the same time and 19 cases were onset. The interval time was from February to 32 years (on average). July). Seminoma is generally given radiotherapy; 5 non-spermatogonia tumors with no retroperitoneal lymphatic metastasis were also treated with radiotherapy 10 years ago. Non-seminoma according to staging, generally for retroperitoneal lymphadenectomy and/or chemotherapy, second
