Experimental inflammation and tumor growth: chemical carcinogenesis in adjuvant arthritic rats

Experimental inflammation and tumor growth: chemical carcinogenesis in adjuvant arthritic rats

P Görög et al. Inflammation. 1979 Sep.

Abstract

Development and growth of primary (methylcholantrene or benzpyrene-induced) sarcomas in adjuvant arthritic rats were investigated and compared with the chemical carcinogenesis in normal healthy animals. When carcinogen and adjuvant were applied in the same time, tumor development and growth rate did not differ significantly from nonarthritic controls. When carcinogen was applied to rats with fully established arthritic disease, development and growth of tumors were significantly enhanced. In the latter case local and systemic adjuvant disease was more severe in tumor-bearing rats. Enhanced chemical carcinogenesis in arthritic rats can be explained by a defective immune responsiveness in the chronic stage of arthritis.
