Radiotherapy was till 1960s-1970s of the last century principal part of treatment of both seminomas and nonseminomas. Recognition of relative radioresistence of nonseminoma limited radiotherapy indication to seminomas only.
Further development led to the revisions of indication of adjuvant treatment, to reduction of radiotherapy volumes and doses and to use of chemotherapy as alternative to irradiation. Contemporary radiotherapy has a role in the treatment in stage I-II seminoma in patients not suitable for surveillance or chemotherapy.
Three-dimensional conformal radiotherapy is a preferred technique.
