Reduced BEP 療法による導入化学療法が有用であった性腺外胚細胞腫瘍の1例

Abstract

A 21-year-old man with chief complaints of left hypochondriac and chest pain was shown to have multiple masses in the lung, a pleural effusion in the right cavum thoracis, a mediastinal mass, and lymphadenopathy detected by computed tomographic scan. He was diagnosed with an extragonadal germ cell tumor based on pathologic findings from lung biopsies and elevation of the serum total human chorionic gonadotropin. He underwent a reduced chemotherapy regimen consisting of bleomycin, cisplatin, and etoposide (reduced BEP) to lower the risk of acute respiratory distress syndrome (ARDS), a manifestation of choriocarcinoma syndrome, which occurs at induction chemotherapy with the full-dose BEP regimen. Choriocarcinoma syndrome did not develop during chemotherapy, and he has been disease-free since salvage chemotherapy and subsequent retroperitoneal lymph node dissection.
