No data on the role of chemotherapy in recurrent ependymal tumors are available in adults. The aim of the current study was to investigate outcomes after salvage chemotherapy in this setting.


A retrospective review was made of the charts of 28 adults (> or = 18 years) with progressive or recurrent ependymal tumors after surgery and radiotherapy, who received chemotherapy between 1993 and 2003 in 3 institutions of the Gruppo Italiano Cooperativo di Neuro-Oncologia network.


Thirteen patients (46.3%) received cisplatin-based chemotherapy (Group A) and 15 (53.7%) received regimens without cisplatin (Group B). Platinum-based chemotherapy yielded 2 complete responses (CR) (15.4%) and 2 (15.4%) partial responses (PR), whereas 7 patients (53.8%) remained stable (SD). After regimens without cisplatin, there were no CR, 2 PR (13.3%), and 11 SD (73.3%). The overall median time to progression was 9.9 months (95% confidence interval [95% CI], 7.5-21.7 months), 9.9 months (5.2-not reached) for Group A and 10.9 months (95% CI, 7.17-23.9 months) for Group B. The overall median survival (OS) was 40.7 months (95% CI, 16-not reached), 31 months (21-not reached) for Group A and 40.7 months (13.4-not reached) for Group B.


Cisplatin-based chemotherapy achieved a higher response rate, but did not prolong disease progression-free survival or OS. More active regimens for the salvage treatment of ependymal tumors have yet to be found.
