summary

Objective. The aim of the study was retrospective analysis of the incidence,
management methods and results of treatment of the patients with bilateral
testicular tumours, .
Material and methods. Among 239 patients treated for testicular tumours, in
7 (2,93%) tumours of the contralateral testis were also observed. A biopsy of
the contralateral testis in 16 patients with risk factors led to the detection of
carcinoma in situ (CIS) in 2 cases. 4 patients had identical histopathological
findings in both testes - seminomas and a lymphoma, whereas in the remaining
cases the types of tumours were different. Bilateral tumours were detected
simultaneously in 3 patients, and in 6 remaining cases the interval between
the diagnosis of the first and the second tumour ranged from 6 months to 6
years (mean 33 months). The methods of treatment of the tumour in the first
testis: radiotherapy, chemotherapy or retroperitoneal lymphadenectomy were
instituted according to histopathological diagnosis and clinical stage of the
disease. The tumours of the contralateral testis were treated using similar
methods and taking into account the methods applied previously. CIS was
treated without surgical castration, applying radiotherapy in one case and
chemotherapy in the other. The patient with the lymphoma died 2 years after
treatment and the remaining 6 ones survived during the period of follow-
up, ranging from 1.5 to 16 years (mean 7.7 years).
Conclusions. The authors present good results of treatment of bilateral germ
cell tumours of the testes. Higher incidence of this disease in patients
previously treated for germ cell tumours indicates the necessity of long-
term follow-up and periodic control examinations of the contralateral testis.
If Coincident risk factors are present, a control biopsy of the contralateral
testis is recommended, which may lead to early detection of CIS and
institution of effective conservative treatment.
