Abstract
The effects of nonsteroid antiinflammatory drugs (acetylsalicylic acid and celecoxib) on N-nitrosodiethylamine-induced carcinogenesis in the liver and esophagus were studied in rats. The inhibitory effect of celecoxib on carcinogenesis was more pronounced (in comparison with acetylsalicylic acid), which manifested in a significantly decreased incidence of neoplastic changes in the liver tissue (from 91.7 to 65.2%), number of tumors in the esophagus (from 4.13 to 2.61 tumor/rat), and in delayed malignization in the liver and esophagus. The incidence of erosions and ulcers of the gastric mucosa was significantly lower after celecoxib treatment. These data indicate that celecoxib inhibits N-nitrosodiethylamine-induced carcinogenesis in the liver and esophagus.
