Adoptive immunotherapy using OK-432-activated mononuclear cells (OK-MCs) offers cell-mediated and cytokine-mediated pathways for antitumor activity. The effectiveness of direct intratumoral administration of OK-MCs via a catheter/reservoir system was studied in patients with malignant brain tumors. Seventeen patients, 12 with malignant glioma, four with metastatic adenocarcinoma, and one with primary sarcoma of the brain, were treated by OK-MC therapy (1.0 to 11.2 × 107 cells/person) between June 1989 and April 1999. The OK-MC therapy was given to patients with tumors progressing despite previous cytoreductive surgery, radiation, or chemotherapy. Adverse effects seen after the therapy were fever in 10 patients, seizure in two patients, and hypotension in one patient. Evaluation by computed tomography or magnetic resonance imaging revealed that seven patients showed no change including three with minor response, and 10 showed progressive disease. Adoptive immunotherapy using OK-MC was safe and well tolerated, but the therapeutic potential is limited.
