Teniposide (VM-26) in brain tumors.


PMID 1411642

Abstract

Although teniposide activity in glioma was reported as early as 1971, it is only within the last 2 to 3 years that its effectiveness in small cell lung cancer and, most dramatically, in associated brain metastasis, has undergone long overdue systematic investigation. The drug appears to enjoy preferential uptake by brain-tumor tissue compared with disease-free brain tissue. Single-agent activity of teniposide in astrocytomas has been widely reported but the data are difficult to interpret due to differences among studies in definition of response and response duration. Combination therapy has focused primarily on teniposide with nitrosoureas and, again, definition variations have made it difficult to evaluate data. Similar problems plague trials by one group of investigators who reported that the combination of teniposide with doxorubicin and lomustine resulted in regression or improvement in significant percentages of their patients. While many studies indicate that teniposide has significant potential in treatment of adult glioma, controlled trials are needed to evaluate and optimize the use of this agent.
