Correlations between molecular profile and tumor location in Chinese patients with oligodendroglial tumors

We conclude that molecular subsets of oligodendroglial tumors may arise preferentially in certain lobes of the brain, with tumors having LOH 1p and LOH 19q occurring most frequently in the nontemporal lobes. These findings suggest that molecular subsets of oligodendroglial tumors may arise from site-specific precursor cells, which has provided some information for the current management of these neoplasms in China.
