Abstract

In contrast to disseminated extraneural germinoma, systemic chemotherapy in disseminated central nervous system germinoma often results in only transient responses. After surgery, cytoreduction was accomplished with systemic multiagent platinum-based chemotherapy in 4 consecutive patients known to have a poor prognosis, due to central nervous system germinoma at more than one anatomic site. When tumor enhancement resolved (i.e., blood-brain barrier integrity was restored), intensive consolidation therapy with carboplatin and etoposide was given in association with mannitol-induced osmotic blood-brain barrier disruption. Complete responses occurred in all 4 patients and currently 3 are tumor-free without radiotherapy 24-40 months from diagnosis, suggesting the importance of increased drug delivery for an extended period.
