Influence of aspirin and/or anabolic steroid (nandrolone decanoate) on experimental metastasis formation.
The influence on transpulmonary passage by an inhibitor of platelet aggregation, aspirin, and/or anabolic steroid, (Nandrolone decanoate), was investigated in syngeneic CBA mice. An increase of extrapulmonary metastases was used as a measure of increased redistribution of tumor cells from lungs to other organs. Aspirin alone did not reduce metastasis formation in lungs and did not significantly increase transpulmonary passage of tumor cells. The anabolic steroid increased the metastasis crop only in the lungs. However, treatment with the two compounds together increased the metastases in lungs and extrapulmonary organs. The results disclosed that in this system inhibition of platelet aggregation did not reduce metastasis formation but in combination with another drug, an anabolic steroid, it increased the number of experimental metastases.
