[Importance of post-therapeutic computer tomography follow-up studies of patients with malignant testicular tumors].

120 patients with malignant tumours of the testicles were subjected to follow-up studies for up to 7 years after the completion of therapy. In 27 cases (22%) metastases were found, which appeared almost exclusively within the first 3 years after treatment. There was definite evidence of metastasis in 9 out of 46 cases (19%) of seminoma and with 18 out of 74 nonseminomatous tumours.
