Summary of "Toxicity and efficacy of lomustine and bevacizumab in recurrent glioblastoma patients."

The combination of lomustine and bevacizumab is a commonly used salvage treatment for recurrent glioblastoma (GBM). We investigated the toxicity and efficacy of lomustine plus bevacizumab (lom-bev) in a community-based patient cohort and made a comparison to another frequently used combination therapy consisting of irinotecan plus bevacizumab (iri-bev). Seventy patients with recurrent GBM were treated with lomustine 90 mg/m2 every 6 weeks and bevacizumab 10 mg/kg every 2 weeks. Toxicity was registered and compared to the toxicity observed in 219 recurrent GBM patients who had previously been treated with irinotecan 125 mg/m2 and bevacizumab 10 mg/kg every 2 weeks. The response rate was 37.1% for lom-bev and 30.1% for iri-bev. Median progression-free survival (PFS) was 23 weeks for lom-bev and 21 weeks for iri-bev (p = 0.9). Overall survival (OS) was 37 weeks for lom-bev and 32 weeks for iri-bev (p = 0.5). Lom-bev caused a significantly higher frequency of thrombocytopenia (11.4% grade 3-4) compared to iri-bev (3.5% grade 3-4). Iri-bev patients had more gastrointestinal toxicity with regard to nausea, vomiting, diarrhea, constipation and stomatitis. Within the limitations of the study lom-bev is a well-tolerated treatment for recurrent GBM, although hematological toxicity may be a dose limiting factor. No significant differences between lom-bev and iri-bev were observed with regard to PFS or OS. The differences in toxicity profiles between lom-bev and iri-bev could guide treatment decision in recurrent GBM therapy as efficacy is equal and no predictive factors for efficacy exist.

Medical and Biotech [MESH] Definitions

Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)

An alkylating agent of value against both hematologic malignancies and solid tumors.

Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.

The relative equivalency in the efficacy of different modes of treatment of a disease, most often used to compare the efficacy of different pharmaceuticals to treat a given disease.

A nonclassical folic acid inhibitor through its inhibition of the enzyme dihydrofolate reductase. It is being tested for efficacy as an antineoplastic agent and as an antiparasitic agent against PNEUMOCYSTIS PNEUMONIA in AIDS patients. Myelosuppression is its dose-limiting toxic effect.
