Abstract
We studied tumor-host interactions in 47 patients with NPC. The local infiltration of T-lymphocyte subsets was investigated by an immunoperoxidase technique using monoclonal antibodies. Biopsy specimens of patients without cervical metastasis showed more T-lymphocyte (T11) infiltration. The amount of Leu-3a (helper/inducer) and T8 (cytotoxic/suppressor) cell infiltration did not correlate with the age, sex, clinical stage, and peripheral blood T4 and T8 cells of the patients. A higher incidence of Leu-3a cell infiltration was found in patients with high serum IgA antibody titers to EBV VCA. A trend of better prognosis was revealed in those cases with no or slight stromal T8 cell infiltration. A local immune response was found to exist which may prevent the spread of NPC to the cervical nodes, but this needs further study to evaluate the local infiltration of T-lymphocyte subsets as a prognostic indicator.
