Abstract

Seven glioblastomas were studied between 1 and 6 months after intratumoral injection of autologous lymphocytes and human lymphoblastoid interferon. Morphological study showed a great number of lymphocytes within the tumor tissue, and interactions between lymphocytes and glioblastoma cells, suggesting a killing phenomenon. These data support the potential usefulness of adoptive immunotherapy in patients with glioblastoma by means of intratumoral administration of activated lymphoid cells.
