Impaired cell-mediated immunity function in thyroid cancer.

Immunological parameters were studied in 31 patients with thyroid cancer. Serum immunoglobulin levels, T and B cell percentages in peripheral blood, showed no significant difference as compared with those of control group. The blastogenesis with phytohemagglutinin P (PHA) was significantly reduced, especially, in those having larger tumor size or metastasis or in those over age 60. The positive rate of skin test with purified-protein-derivative (PPD) and Streptokinase-Streptodornase (SK-SD) was also markedly reduced. The impaired blastogenesis of lymphocyte and reduced positive rate of skin test in those cancer patients suggested that the cell-mediated immunity function, in spite of adequate count of T-cells, was impaired.

Thyroid cancer after irradiation.

Nine patients with thyroid cancer who had received irradiation on the thyroid region (four for breast cancer with deep x-ray or Co60, one for a skin lesion with deep x-ray and four for hyperthyroidism with I131) have been discussed. These cases might be within the range of statistical coicidence, but the potential carcinogenic effect of irradiation could not be ruled out completely. The need for detailed examination of the thyroid gland before and for many years after irradiation and early removal of thyroid gland nodules which develop after I131 treatment are emphasized.
