Alcohol and hamster buccal pouch carcinogenesis
Oral Surgery, Oral Medicine, and Oral Pathology

Abstract:
Alcohol was shown to enhance the carcinogenic effect of DMBA applied to hamster buccal pouch. DMBA animals given alcohol developed dysplastic leukoplakic lesions and epidermoid carcinomas 2 weeks ahead of water-drinking control animals. The tumors also grew to larger size, were more invasive, and were more anaplastic histologically. Forty young adult Syrian hamsters were divided into four groups (alcohol-DMBA, DMBA control, untreated control, and alcohol control) and were killed after 10, 12, and 14 weeks of DMBA applications three times weekly. Alcohol was given as a 10 percent solution instead of drinking water.
