Glioblastoma is the most aggressive and most common type of primary brain cancer. Standard treatment at diagnosis is surgery followed by high dose radiation therapy and chemotherapy. Despite initial treatment nearly all patients will experience recurrence of the tumor with a dismal prognosis. There is no consensus on standard of care at recurrence. Reoperation is associated with a high risk of complications and further conventional radiation therapy is often not possible as the maximum tolerated dose to the normal brain has already been given. In addition most tumors have developed resistance towards chemotherapy. Stereotactic radiosurgery (SRS) may be administered despite prior initial radiation treatment but in order to avoid radiation induced complications only limited doses to limited tumor volumes can be applied. Developing new strategies to improve the effect of radiation selectively on tumor cells without simultaneously increase the radiation induced damage of normal brain would be valuable. The investigators have shown in experimental studies that the drug sulfasalazine enhances the number of cancer cells that dies as result of radiation therapy and thereby improves survival in combination with SRS in animals with glioblastoma. Sulfasalazine inhibits the production of an antioxidant that normally protects the tumor against radiation. Hopefully the trial will result in a new and more effective treatment option for patients with recurrent glioblastoma.
