1) Malignant Tumors arising in the Lymphatic Tissue of the Tonsil and Nasopharynx There were no differences in radiosensitivity and prognosis of malignant tumors arising in the lymphoid tissue due to the differences in the anatomical sites in which the tumors occurred. A larger percentage of reticulosarcoma of syncytial type developed in the nasopharynx. 2) The Radiosensitivity and Prognosis of Tumors in Relation to their Histopathological Classification. Reticulosarcomas of syncytial type (undifferentiated types) were less radiosensitive, and their prognosis was worse than that of reticular type (differentiated type). Lymphosarcomas were more radiosensitive, and their prognosis was better than that of reticulosarcomas. 3) Tumor cells which divide themselves into larger numbers of daughter cells in mitosis were less radiosensitive than those which divide themselves into smaller numbers of daughter cells.
