Abstract
We examined correlations between cellular immunity and clinical courses of malignant tumors of bone and soft tissue, using immunological skin tests.
We used purified PHA, Su-Polysaccharide, Streptokinase-Streptodornase and PPD.
1) Values of initial skin tests correlated with the prognoses of malignant tumors.
2) Values of initial skin tests of patients with malignant tumors were lower than those of patients with benign tumors and healthy people.
3) Values of skin tests got lower as the clinical stage went worse.
Several skin tests must be performed frequently, and we should summarize them with other clinical features and serological findings to know the stage and prognosis of malignant tumors.
