Abstract: | Glioblastoma multiforme patients presenting with recurrence following multimodality therapy have limited palliative treatment options when the major modalities of therapy including surgery, radiochemotherapy and adjuvant chemotherapy have been exhausted. The authors introduce a clinical and radiological indication-solving algorithm and provide outcome rates of a glioblastoma recurrence cohort. Sixty six consecutive adult patients with recurrent glioblastoma who underwent a combined scheme of salvage treatments consisting of reoperation, high dose rate (HDR) brachytherapy and chemotherapy were included in this prospective study and were compared to a historical control group of 24 recurrent glioblastoma patients who have been treated with intensive temozolomide chemotherapy as the only treatment modality. Median follow-up was 32 months (range 28–36 months). Median survival was 9 months for the entire cohort after salvage treatment and can be translated into a 3-month improvement in survival compared to the control group of patients with glioblastoma recurrence treated with temozolomide alone (P = 0.043). Toxicity and adverse events of reoperation, HDR brachytherapy combined with chemotherapy were quite favourable compared to intensive temomozolomide chemotherapy as the only treatment. Our experience suggests that a combined salvage treatment plan appears to be both feasible and effective and can be considered in selected patients affected by recurrent high grade gliomas. The authors’ clinical and radiological indication-solving algorithm may assist in providing the best possible salvage treatment for this difficult population. |
