[Study activities for testicular cancer].

Testicular cancer is one of the few tumors which are curable even at an advanced stage. This has been achieved both by the use of platinum based chemotherapy and by the interdisciplinary approach by urologists, internal oncologists and radio-oncologists. In 1988, the Interdisciplinary Testicular Cancer Study Group was founded. The aim of this group is to initiate clinical trials to improve the results in the treatment of this tumor. Furthermore, the group has published evidenced-based national and international guidelines for testicular cancer. This article gives an overview on the work of the group including current studies.
