This work studies the effect of nonspecific antitumoral immunity produced by the "Corynebacterium Parvum" vaccine (C.P.) and Stilbostal on the development of Walker 256 carcinosarcoma intratesticularly grafted to hyper- or hypothyroidized Wistar rats. The thyroid hormone level was altered by administration of thyroxin, Alkiron or surgical thyroidectomy. The C.P. vaccine was given in a mixture with tumoral cells suspension and the treatment with the Stilbostat drug was started 5 days from grafting. The results show that C.P. administered in a mixture with tumoral cells suspension causes marked inhibition of the development of the primary tumor and metastasis, an effect which is not significantly influenced by the thyroid hormone level. The antitumoral effect of the Stilbostat drug is enhanced by administration of C.P. in tumoral cells suspension. The greatest effect produced by Stilbostal was noted in the hyperthyroidized lots in which the tumor was administered in a mixture with C.P.

The effect of nonspecific antitumoral immunity caused by BCG on intratesticular development of 256 Walker carcinosarcoma has been studied on male hyper- or hypothyroidectomized rats. Thyroid hormones level was altered by administration of T4. Alkiron or thyroidectomy. The time and route of BCG administration differed from one lot to another. Authors' results show that administration of BCG before or concomitantly with the graft stimulates tumor development, whereas administration of BCG mixed with a suspension of tumoral cells causes marked inhibition in the development of primary tumor and metastasis, an inhibition which is not influenced by the thyroid hormones level. In vitro proliferation of the tumoral cells as well as histopathologic examination of the tumors suggest the involvement of a complex process in achieving the nonspecific antitumoral immunity.
