Lymphography in tumors of the testicles

In 45 patients with tumours of the testes (5 seminomas, 40 nonseminomas) the pretherapeutic lymphographic diagnosis could be histologically tested after a retroperitoneal removal of lymph nodes. The lymphographic security was more than 82%; 4 diagnoses each were falsely positive and falsely negative. The sensitivity was 81%, the specificity 83%. With these results the lymphography meets the requirements which are set for a diagnostic method and is relevant to therapy. An increase of the security by additional examinations (tomography and cavography) is possible. Taking into consideration its limits bipedal lymphography belongs to the obligatory spread diagnosis in tumours of the testes; its results allow an estimation of the spread of the tumour, the therapeutic effect and the prognosis of the tumour disease.
