The effect of chronic ethanol intake on the growth and spread of some murine tumors.

The effect of chronic ethanol intake on the growth and spread of some murine tumors has been investigated. The treatment had no effect on the B 16 melanoma but tended to decrease the number of Ehrlich ascites cells. In the case of the Lewis lung carcinoma, administration of ethanol for two weeks tended to lower the number of metastases to the lung without significantly affecting the primary tumor size, whereas more prolonged ethanol intake decreased the weight of the primary tumor in addition to decreasing its dissemination.
