Purpose: Retrospective analysis of ten cases of germinoma of the central nervous system treated in Pitié-Salpêtrière Hospital, Paris.
Patients and methods: Ten male patients were treated from 1997 to 2005 for histologically verified primary seminoma of the central nervous system. The median age was 27 years (range 18-40 years). Our option for the treatment was the association of 3-4 cycles of neoadjuvant chemotherapy (cisplatin and etoposide) to radiotherapy. Five patients received a craniospinal radiotherapy of 30 Gy (for one patient 36 Gy) followed by a tumoral boost from 20 to 24 Gy. For five patients, irradiated volume was limited to the tumour, total dose from 24 to 54 Gy (for three patients the total dose was from 24 to 30 Gy). Surgery was used for five patients, but only in one case was macroscopic complete.
Results: Six patients were in situation of complete remission after neoadjuvant chemotherapy. All the patients were in situation of complete remission after the irradiation. All the patients were alive free of disease with a median follow-up 46 months (range 13-90 months).
Conclusion: In spite of the fact that the intracranial germinal tumours are not the subject of a consensual treatment strategy, this retrospective analysis pleads in favour of chemotherapy followed by limited dose and volume irradiation.
