How We Treat Recurrent Glioblastoma Today and Current Evidence

Recurrent glioblastoma (rGBM) has no standard treatment. Despite a better molecular knowledge, few therapies have brought changes in clinical practice so far. Here we will review the current data evaluating the re-radiation, re-resection, bevacizumab, and cytotoxic chemotherapy agents in this setting. We will also discuss the advances of immunotherapy and the possible benefit of this treatment for patients with rGBM.Next-generation sequencing is increasingly utilized in the clinical practice of neuro-oncologists, bringing gene mutations as targets for therapies. As in other solid tumors, immunotherapy has been also extensively studied in rGBM, with interesting results in phase I and II trials. The most promising therapies in the horizon are combinations including immune checkpoint inhibitors, virotherapy, vaccines, and monoclonal antibodies. Although re-radiation, re-resection, bevacizumab, and chemotherapy are still the most widely used therapies for treating rGBM, the clinical benefit from these treatments is still not well established. Preliminary results of studies with immune checkpoint inhibitors were disappointing, but virotherapy emerges as more promising immunotherapy in rGBM, especially in combination with other strategies. In addition to the gain in overall survival, the improvement in the quality of life of these patients is also expected.
