• Salvage chemotherapy
• Recurrent glioblastoma

In newly diagnosed glioblastoma multiforme, surgery, combined radio and chemotherapy, and adjuvant chemotherapy with temozolomide is the standard of care. Therapy for recurrent glioblastoma is less well established and comprises re-operation, re-irradiation, chemotherapy, targeted therapy, inhibition of neoangiogenesis, and others. In this observational study we recorded the efficacy and toxicity of a combination of procarbazine, carmustine, and vincristine (PBV) for 69 patients with recurrent and/or progressive glioblastoma after surgery, concomitant radio and/or chemotherapy, and adjuvant first-line temozolomide therapy. Of 41 patients evaluable for response by MRI, partial response was observed for one, minor response for three, stable disease for at least 6 weeks for ten, and immediate progression for 27. Median PFS was 15 weeks, and PFS-6 was 21 % for 57 patients who could be followed; 12 other patients were lost to follow-up after application of the first PBV cycle. Grade III or IV leucopenia and/or grade III or IV thrombocytopenia were seen in 26 % and 26 % of cycles, respectively. Haematological complications led to interruption of treatment for four (7 %) patients. Non-haematological toxicity was moderate. Salvage PBV therapy in recurrent and/or progressive glioblastoma, pre-treated with temozolomide-based chemotherapy as first-line treatment, is of limited efficacy with a small number of long-term survivors, but is hampered by relevant myelotoxicity.
