The authors propose "decreased-dose-intensity" PCV (procarbazine, lomustine [CCNU], and vincristine) chemotherapy for Asian patients with oligodendroglial tumors. In this study, all seven patients with oligodendroglioma (OD) and eight with anaplastic oligodendroglioma (AO) had objective responses or stable disease. Median progression-free survival was greater than 29 months (OD) and 36.5 months...

Abstract Background Chemotherapies used for the treatment of primary brain tumors frequently induce hematological toxicity. Thrombocytopenia represents main cause stopping chemotherapy Here we explored incidence, and consequences exposure survival, thrombocytopenia induced by lomustine at first recurrence glioblastoma. Methods We performed a retrospective analysis glioblastoma, its delivery, as...

Lomustine is a nitrosourea anticancer agent shown to be effective for treatment of childhood medulloblastoma. In silico substructure searches produced 17 novel nitrosourea agents analogous to lumustine and retaining activity for DNA alkylation and cytotoxic activity. The mean values for Log P, polar surface area, formula weight, number of oxygens & nitrogens, and rotatable bonds were 2.524, 62....

Bevacizumab is used to treat glioblastoma; however, no current biomarker predicts its efficacy. We used an exploratory cohort of patients treated with the radiochemotherapy then bevacizumab or chemotherapy at recurrence (N = 265). Bevacizumab use increased median overall survival (OS) 18.7 vs 11.3 months, p = 0.0014). In multivariate analysis, age, initial surgery, neutrophil count, Karnofsky s...

Bevacizumab, a humanized monoclonal antibody designed to inhibit vascular endothelial growth factor, is effective in combination with chemotherapy against malignant gliomas. We examined the therapeutic effects and toxicity of bevacizumab as a single agent for the treatment of recurrent malignant glioma. This is a retrospective analysis of a case series of 18 adult patients, diagnosed with recur...

AIM To determine the relationship between prescribed dose-intensity of chemotherapy and survival in childhood medulloblastoma. MATERIALS AND METHODS A total of 55 trials from 1970-2009 were identified, 30 were eligible for analysis, with individual treatment regimes with 5-year (or more) outcome figures. Relationships of outcome to dose-intensity were analysed using weighted regression. RES...

Tyrosine kinase signaling through the vascular endothelial growth factor receptor 2 (VEGFR2), platelet-derived growth factor receptor- α (PDGFR-α) and KIT cell surface receptors mediates neo-angiogenesis and contributes to cancer cell survival in recurrent anaplastic and low-grade glioma. Thirteen patients with temozolomide-refractory recurrent anaplastic or low-grade glioma were treated with s...

Abstract Background Treatment options for recurrent glioblastoma are limited and with the possible exception of regorafenib, no agent has demonstrated superior activity to lomustine. Therefore, there is an urgent need more effective treatment strategies glioblastoma. Here, we investigated different combinations based on tumor-stroma targeting antibody-cytokine fusion protein L19TNF in preclinic...
