Regression of Local and Distant Tumor Growth by Tissue Expansion

Abstract

To study this in the experimental animal, Fischer rats were injected intradermally with 13762 mammary carcinoma cells and assigned at random to one of four groups: group I (n=24), nonoperated control; group II (n=22), creation of a sham pocket beneath the tumor group III (n=21), expander placed beneath the tumor bed, unexpanded; and group IV (n=22), a tissue expander placed beneath the tumor bed, expanded
