    Notes: Summary The percent distribution of T- and B-lymphocytes in tonsilar tissue of 122 patients from 2–68 years and both sexes was investigated. T-cells were determined by the E-rosetting technique and B-cells by immuno-fluorescence. We found 50.3% B-cells and 30.6% T-cells in tonsilar tissue. There was a significant decrease of IgM-receptor carrying cells with increasing age and with a converse behavior of the sum of IgA-, IgD-, IgE-receptor B-cells. In tonsils with acute inflammation and with hyperplasia IgM cells were also increased significantly when compared to cell counts in chronic tonsillitis. The results are discussed and compared to data from the literature.

    Description / Table of Contents: Zusammenfassung Dreizehn Fälle nasopharyngealer Carcinome (NPC) und 16 Fälle nicht-nasopharyngealer Carcinome in der gleichen oder in benachbarter Region wurden klinisch, pathologisch und immunologisch untersucht. Alle Tumoren wurden entsprechend der TNM-Klassifikation eingruppiert, und das Ausbreitungsstadium und der Verlauf der Erkrankung wurden korreliert mit dem histologischen Tumortyp, der T- und B-Lymphozytenverteilung im Tumorgewebe und im peripheren Blut sowie mit den Antikörpertitern gegen Epstein-Barr-Virus (EBV). Die Ergebnisse zeigten deutliche Beziehungen zwischen Abnahme prozentualer T- und B-Zellen im Tumorgewebe und T-Zellen im peripheren Blut und dem Ausbreitungsstadium des Tumors bei NPC als auch bei nicht-NPC-Fällen; eine teilweise Ausnahme bildeten lediglich lymphozytenreiche Neoplasien (lymphoepitheliale Carcinome und maligne Lymphome). Antikörper gegen EBV (Frühantigen und Kapselantigen) zeigten eine mit dem Tumorstadium zunehmende Erhöhung bei NPC-Fällen, jedoch nicht bei nicht-NPC-Fällen. Auch bei NPC-Fällen wurde dieses Phänomen nur bei zwei histologischen Typen beobachtet: Bei anaplastischen Carcinomen und bei lymphoepithelialen Carcinomen; die Titer der übrigen Tumortypen blieben unauffällig. Die Bedeutung dieser Befunde wird diskutiert.
    Notes: Summary Thirteen cases of nasopharyngeal carcinoma (NPC) and 16 cases of non-NPC tumors in the nasopharynx or in adjacent locations were investigated clinically, immunologically, and pathologically. All tumors were classified according to the TNM classification, and the stage and course of the disease was correlated with the histological tumor type, the T- and B-cell distribution in tumor tissue and in the peripheral blood, as well as with antibody titers against Epstein-Barr virus (EBV). The results showed a positive correlation of decreased T- and B-cells in tumor tissue and of decreased T-cells in the peripheral blood with the extend of the tumor in both NPC and non-NPC cases, with some exceptions of lymphocyte rich neoplasms (lymphoepithelial carcinoma and malignant lymphoma). Antibodies against EBV (early antigen and capsid antigen) became progressively elevated with increasing tumor stage in NPC-cases but not in non-NPC cases. The latter, however, was observed only in two histological types of NPC's: anaplastic carcinoma and lymphoepithelial carcinoma; titers in the remaining tumor types stayed insignificant.
