[A case report of extragonadal germ cell tumor with special reference to VAB-6 therapy].

A 24-year-old man with a large abdominal mass in addition to the left lymph node swelling was referred to our clinic. Neither testicular nodulus nor overt evidence of tumor development in the scrotal cavity was confirmed by careful palpation and testicular biopsy. Values of lactate dehydrogenase, alpha-fetoprotein, human chorionic gonadotropin (HCG) and beta-HCG in the serum were markedly elevated. The specimen removed from the left cervical lymph node demonstrated mixed type of choriocarcinoma and embryonal carcinoma. A partial response near complete remission was achieved following the VAB-6 combination therapy (cyclophosphamide, vinblastine, actinomycin D, bleomycin, cis-platinum). The patient has been in good health with normal tumor markers and abdominal CT findings.
