A study on metals content in patients with colorectal polyps

Area of Science:

• Environmental Science
• Oncology
• Biochemistry

Background:

• Data regarding the role of metals in colorectal polyps is limited.
• Understanding these associations may offer insights into early-stage colon cancer development.

Purpose of the Study:

• To investigate the association between the concentration of 15 chemical elements and the risk of colorectal polyp development.
• To compare metal levels in colorectal polyps with adjacent normal tissue and healthy individuals.

Main Methods:

• Analyzed the concentration of 15 chemical elements (including Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Pb, Se, Sr, and Zn).
• Evaluated metal concentrations in colorectal biopsies from healthy individuals, polyp tissues, and corresponding non-polyp tissues from the same individuals.

Main Results:

• Iron (Fe) concentration was significantly higher in polyps compared to normal tissues.
• Barium (Ba), cadmium (Cd), and mercury (Hg) levels were significantly lower in polyps.
• Selenium (Se) showed significant accumulation in polyps compared to healthy tissues.

Conclusions:

• Specific elemental differences between polyps and normal tissues suggest a role for both essential and non-essential elements in early colorectal carcinogenesis.
• Further research is warranted to confirm the involvement of these elements in neoplastic processes.
