    Abstract:
    To assess whether therapeutic efficacy is related to intra-arterial (IA) mannitol infusion prior to ACNU and cisplatin (CDDP) for brain metastases from lung cancer, clinical results of patients with and without IA mannitol infusion were compared. Thirty-nine patients were randomly assigned to either a mannitol infusion group (group A) or a non-mannitol infusion group (group B). There were 22 patients in group A and 17 in group B. During radiotherapy, ACNU and CDDP, at a dose of 100 mg/body, were given through the common carotid artery at a rate of 20 mg/min. In group A, 50 ml of 20% mannitol was injected intra-arterially at a rate of 50 ml/min immediately prior to the injection of chemotherapeutic agents. Major complications, such as seizure and neurotoxicity, were not observed. Complete response (disappearance of enhanced tumor mass) was obtained in 72% of group A and in 67% of group B. The median time to tumor progression was 40 weeks for group A and 22 weeks for group B. The median survival time (MST) was 45 weeks for group A and 30 weeks for group B. The survival time was significantly longer in group A as compared to group B (p < 0.05). When the patients who died of failure of vital organ systems other than brain complications were excluded in calculating the survival time, the MST was 69 weeks for 11 patients of group A and 34 weeks for 7 patients of group B. These data suggest that an effort to increase drug delivery to the brain tumor may indeed lengthen the survival time of patients with brain metastases from lung cancer.
