Bevacizumab for recurrent alkylator-refractory anaplastic oligodendroglioma.
BACKGROUND A retrospective evaluation of single agent bevacizumab was carried out in adults with recurrent alkylator-refractory 1p19q codeleted anaplastic oligodendrogliomas (AO) with an objective of determining progression-free survival (PFS). There is no standard therapy for alkylator-resistant AO, and hence a need exists for new therapies. METHODS Twenty-two patients aged 24 to 60 years wi...
متن کاملEffectiveness of interferon-beta and temozolomide combination therapy against temozolomide-refractory recurrent anaplastic astrocytoma
BACKGROUND Malignant gliomas recur even after extensive surgery and chemo-radiotherapy. Although a relatively novel chemotherapeutic agent, temozolomide (TMZ), has demonstrated promising activity against recurrent glioma, the effects last only a few months and drug resistance develops thereafter in most cases. Induction of O6-methylguanine-DNA methyltransferase (MGMT) in tumors is considered to...
متن کاملPhase III randomized study of postradiotherapy chemotherapy with combination alpha-difluoromethylornithine-PCV versus PCV for anaplastic gliomas.
PURPOSE In the current study, we sought to determine whether the addition of DFMO (alpha-difluoromethyl ornithine; eflornithine), an inhibitor of ornithine decarboxylase, to a nitrosourea-based therapy procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea, vincristine (PCV) would be more effective as a postirradiation adjuvant therapy for anaplastic gliomas (AG) than PCV alone. PATIENTS ...
متن کاملBenefit with adjuvant chemotherapy in anaplastic astrocytoma.
www.thelancet.com Published online August 8, 2017 http://dx.doi.org/10.1016/S0140-6736(17)31477-0 1 The role of chemotherapy for newly diagnosed anaplastic gliomas, particularly when combined with radiotherapy, has long been unresolved. Over the past few decades, despite no conclusive data, study findings have suggested that the addition of nitrosourea-based chemotherapy to radiotherapy could b...
متن کاملAssessing Biological Response to Bevacizumab Using 18F-Fluoromisonidazole PET/MR Imaging in a Patient with Recurrent Anaplastic Astrocytoma
We present our initial experience in using single modality fluoromisonidazole (FMISO) PET/MR imaging to noninvasively evaluate the biological effects induced by bevacizumab therapy in a patient treated for recurrent high grade glioma. In this index patient, bevacizumab therapy resulted in the development of nonenhancing tumor characterized by reduced diffusion and markedly decreased FMISO uptak...
