title: Pediatric intracranial germinoma treated with chemotherapy alone.
abstract: BACKGROUND
  Pediatric intracranial germinoma treated with radiotherapy is considered a standard treatment, but may cause significant delayed damage to the central nervous system. Chemotherapy has been shown to be effective for the treatment of an intracranial germinoma. In the past 10 years, we treated 11 cases of primary intracranial germinoma with chemotherapy alone. The purpose of this retrospective study is to review the clinical outcome of these patients.
  
  
  METHODS
  Eleven children with newly diagnosed, previously untreated primary intracranial germinomas were treated with six courses of chemotherapy (vinblastine bleomycin, cisplatin and etoposide, VBPE). The response to chemotherapy, relapses and outcomes are reviewed and evaluated.
  
  
  RESULTS
  All 11 assessable children achieved a complete response and are alive, with a median follow-up of 61 months. Five patients with tumors located in the midline position of the brain, including pineal, sellar, suprasellar and hypothalamic areas, had no relapse. Six patients had relapses, and all of them achieved a second complete remission after salvage focal radiotherapy. The time of onset of relapse was from nine to 24 months after chemotherapy, with an average of 16.8 months.
  
  
  CONCLUSIONS
  VBPE chemotherapy was effective for treating newly diagnosed intracranial germinomas. Although a high rate of relapse (6/11) was observed, all of these patients survived with first or second complete remissions. It was beneficial for five children that focal radiation was eliminated and delayed post-irradiation neurologic sequelae were avoided.
