OBJECTIVES. To investigate the efficacy and safety profile of bevacizumab in combination with irinotecan in Hong Kong Chinese patients with recurrent malignant glioma and to determine whether their response differed from that reported in other populations.
DESIGN. Retrospective study.
SETTING. Two private clinics and a public hospital in Hong Kong.
PATIENTS. Fourteen individuals who presented with recurrent glioma presenting to the hospital between November 2005 and November 2009.
INTERVENTION. Salvage therapy with bevacizumab (10 mg/kg) and irinotecan (125 mg/m(2) [340 mg/m(2) for those taking enzyme-inducing antiepileptic drugs]) on a 14-day schedule.
RESULTS. A radiological response was observed in 12 (86%) of the patients, four (33%) of whom had a complete response. The median progression-free survival was 6 (range, 1-15) months; 71% remained progression-free at 6 months. The median overall survival was 18 (range, 9-61) months. The most common adverse events during the bevacizumab and irinotecan treatment period were haematological; five patients had grade 2/3 adverse events. Pulmonary embolism occurred in two patients, one of whom died. Intracranial haemorrhage was not detected in any of the 14 treated patients.
CONCLUSIONS. Bevacizumab plus irinotecan was at least as effective at treating Chinese patients with recurrent glioma as previously reported in clinical trials in different patient populations.
