A cell line was established from a patient with malignant fibrous histiocytoma, which had originated in the maxillary sinus. Using this cell line, sensitivity to chemotherapeutic agents and cytotoxicity against various immunoeffecter cells were tested.
Results: This MFH cell line was sensitive in some degree to adriamycin, 5-fluorouracil, cisplatin, peplomycin, and methotrexate at high doses, but insensitive to mitomycin-C, vincristine and cyclophosphamide. Furthermore, this cell line showed no sensitivity to cytolytic cytokines, such as tumor necrosis factor-alpha and interferon-gamma. Lymphokine activated killer (LAK) cells and lymphokine activated tumor infiltrating lymphocytes (LA-TIL), induced by culture of peripheral blood lymphocytes and TIL respectively with rIL-2 showed high NK and LK activities and remarkable anti-autologous tumor ability.
