Abstract:
Colorectal cancer (CRC) is among the most common types of cancer in the world. Globally a steadily increasing
proportion of elderly people in the world result in approximately 16 million new cases of cancer by the year 2020.
Regarding treatment; Meloxicam was shown to prevent the initiation of chemical-induced tumors, and considered as
anticancer agent by virtue of its anti-proliferative effect, capacity for cell cycle arrest, and pro-apoptotic effects, also
acted as free radical scavenger, in particular superoxide anion oxidation scavenge. The aim of the current study was to
investigate the protective role of meloxicam against colon cancer. The study was carried out on 60 male albino rats,
animals were divided into 5 groups; A: control group, B: animals received S.C. injections of 20 mg 1,2 DMH /Kg b.w, C:
animals received 1, 2 DMH with ad libitum access to water and high fat diet, D: animals fed high fat diet and water ad
libitum. E: animals received S.C. injections of 1,2 DMH and oral 15mg/Kg /day meloxicam/0.1 ml saline. Colon tissues
from all studied groups were stained applying the following techniques: Hematoxylin & eosin, Alcian blue pH 2.5- acid
mucopolysaccharide, Feulgen nuclear staining of DNA, Whole mount staining of colon. The results confirmed the
efficacy of meloxicam inhibiting or delaying growth of aberrant crypt foci in colon. Further research is needed to suppor
