Abstract:
Colorectal cancer is the third most frequent fatal malignant neoplasm in the United States and is expected to cause significant morbidity and mortality. The recent recall of cyclooxygenase-2 inhibitors from clinical trials highlights the need to develop other agents for cancer chemoprevention trials. Intervention strategies with selenium compounds represent a viable option to reduce colon cancer. Here we discuss epidemiologic studies and ongoing clinical trials with selenium. In addition, we discuss preclinical mechanistic studies that provide insights into the biochemical and molecular bases for the anticancer effects of selenomethionine.
Insights
Selenium compounds show promise for colon cancer chemoprevention. Research explores epidemiologic and clinical studies, alongside preclinical data on selenomethionine
Area of Science:
- Oncology
- Nutritional Biochemistry
- Preventive Medicine
Background:
- Colorectal cancer is a leading cause of cancer death in the US.
- The withdrawal of cyclooxygenase-2 inhibitors necessitates alternative chemoprevention strategies.
- Selenium compounds offer a potential avenue for colon cancer prevention.
Purpose of the Study:
- To review epidemiologic and clinical trial data on selenium for colon cancer prevention.
- To discuss preclinical research elucidating the anticancer mechanisms of selenomethionine.
Main Methods:
- Review of published epidemiologic studies on selenium and colon cancer.
- Analysis of ongoing and completed clinical trials involving selenium interventions.
- Examination of preclinical mechanistic studies on selenomethionine's biochemical effects.
Main Results:
- Epidemiologic data suggest a role for selenium in reducing colon cancer risk.
- Clinical trials are investigating the efficacy of selenium compounds.
- Preclinical studies indicate specific molecular pathways targeted by selenomethionine.
Conclusions:
- Selenium intervention is a viable strategy for colon cancer chemoprevention.
- Further research, including clinical trials and mechanistic studies, is warranted.
- Selenomethionine shows potential as an anticancer agent.
