摘要：

Objectives: The incidence of bilateral testicular tumors (BTT) had increased over the preceding decade. The aim of the present study is to analyse a group of patients with BTT and to high-light the need for long-term follow-up of patients treated in a single centre. Material and methods: 27 (2.8%) out of 960 patients with germ-cell testicular tumors (GCTT), treated between 4/1977 and 8/2001, developed bilateral disease. All of them underwent radical orchiectomy (in one patient was done delayed orchiectomy after primary chemotherapy due to advanced disease). Additional treatment was planned according to the histologic type and clinical stage of the disease, and previous treatment as well. The survival data were reviewed. Results: 24 out of 27 patients (88.9%) developed the 2nd tumor metachronously (median interval 66 months, range, 4-197 months) and three (11.1%) had synchronous BTT. Only 7 patients (25.9%) had identical histological types on both sides (6 of them with pure seminomas, one with embryonal carcinoma). Two of three synchronously developed BTT had different histologic types on both sides. GCTT of one histologic type were observed in respect of the first tumor: 11 seminomas, three embryonal carcinomas, in respect of the 2nd tumor: 10 seminomas, three embryonal carcinomas, in respect of the 2nd tumor: 10 seminomas, three embryonal carcinomas and one mature teratoma. GCTT of more than one histologic type were observed in respect of the first and the 2nd tumors: 6 mixed GCTT with seminoma component and 7 without seminoma component. Majority of BTT was presented in clinical stage I (in respect of the first tumor in 70.4%, in respect of the 2nd tumor in 62.9%). The median duration of the follow-up after the diagnosis of the first GCTT was 149 months (range, 13-288 months) and after the diagnosis of the contralateral GCTT was 68 months (range, 1-167 months). Twenty-five patients (92.6%) were alive with NED at their last follow-up visit. Two patients died by mean of 22.5 months (range, 21-24 months) after the 2nd orchiectomy. Conclusions: All patients with unilateral GCTT have an increased risk of developing a contralateral testicular tumor, even decades after diagnosis. Management should be individualised for each patient.
