[Therapy and prognosis of testicular tumors: the teratocarcinoma, results from 52 patients (author's transl)].

: In this retrospective study, the course of the disease was investigated in 52 patients having been irradiated because of malignant teratoma between 1963 and 1975. The patients were ranged as follows: four cases Stage I, thirty cases Stage II, six cases Stage III, twelve cases Stage IV. All histological preparations were graded once more, using the classification of Pugh and Collins. The 5-year survival recovery rates amounted to 100% in Stage I, to 64% in Stage II, to zero in Stage III and IV, and to 47% for all stages. A remarkable difference of the recovery rates in relation to histological findings was observed: MTIA Stage II=83%, all stages=40%; MTIB Stage II=57%, all stages=33%.
