Abstract
Eight patients 4 men and 4 women with a median age of 68 years with non-Hodgkin's lymphoma originating in the thyroid gland were treated at the Japan Red Cross Society Wakayama Medical Center. All patients were treated with radiation therapy and combination chemotherapy. The chemotherapy regimen consisted of pirarubicin, cyclophosphamide, vindesine, and predonisolone administered in 7 cases. According to the LSG classification, the prognosis in 2 cases of medium-sized cell type were poor. Cell types of non-Hodgkin's lymphomas of the thyroid gland thus appear to be significant determinants in patient prognosis.
