Promising survival in patients with high-grade gliomas following therapy with a novel boronated porphyrin

J Clin Neurosci. 2003 Jul;10(4):425-7. doi: 10.1016/s0967-5868(03)00062-6.


Current treatment strategies for high-grade gliomas are inadequate with high rates of disease recurrence and poor overall survival. Photodynamic therapy has been extensively investigated for a variety of tumours including high-grade gliomas. We have previously described a novel boronated porphyrin (BOPP) which has highly selective uptake by tumour cells. A Phase I study documented that BOPP at a dose of 4mg/kg was well tolerated. We report here the survival data arising from this Phase I study. Overall 28 patients (pts) with high-grade gliomas were treated with BOPP photodynamic therapy with a median overall survival (OS) of 14 months (2-48+ months). Sixteen pts had glioblastoma multiforme (GBM) with a median OS of 8 months (2-38+). Of 9 pts with recurrent GBM, the median OS was 11 months (3-38+), with 56% surviving at least 12 months. In conclusion, BOPP photodynamic therapy was associated with encouraging survival particularly in the recurrent GBM setting.
