Effects of linomide on advanced prostate-seminal vesicle cancers in Lobund-Wistar rats

The Prostate
M Pollard

Abstract

Angiogenesis and antiangiogenesis, as applied to oncology, are phenomena in which (1) tumors acquire a new blood vascular system from the host that is needed for their growth progression and metastasis; and (2) factors are produced that interfere with neovascularization, thereby inhibiting growth and metastasis of the tumor. Linomide, a chemical antiangiogenesis agent, inhibited the growth of transplanted tumors in mice and rats and inhibited the early development of metastasizing tumors induced in the prostate-seminal vesicle (P-SV) complex of genetically susceptible Lobund-Wistar (L-W) rats. L-W rats with small induced P-SV tumors were treated with a recommended dosage of linomide (100 mg/kg BW/day) by the intraperitoneal and oral routes. The rats were monitored for the next 1-2 months, and the primary and metastatic tumors were compared with related data in drug-free tumor-bearing control rats. P-SV tumors in linomide-treated and untreated control rats continued to grow, except that in the former (1) the tumors were marginally smaller, (2) the centers of the primary P-SV tumors had failed to grow, (3) the peripheral areas of the tumors contained actively proliferating tumor cells, and (4) metastatic P-SV tumors in the lungs ...Continue Reading
