[Similar evolution, with cerebral metastases, of testicular cancers in 2 non-twin brothers].

The authors describe two cases of germinal carcinoma of the testis. The two patients were brothers, but not twins. The evolution of the disease was the same in both cases, with cerebral metastases. The etiology was not discovered but the localization of the metastases in the brain would seem due to the fact the antimitotic drugs used in therapy failed to cross the brain blood barrier.
