Summary
Establishing a biological specimen bank is crucial for future cancer research, as validated biomarkers for diet
Area of Science:
- Nutritional Epidemiology
- Biomarker Development
- Cancer Research
Background:
- Lack of validated clinical biomarkers for evaluating diet's impact on cancer.
- High scientific value in biobanking for future research.
- Need for robust methods to assess dietary and non-dietary factors in cancer etiology.
Purpose of the Study:
- To establish and validate procedures for banking biological specimens for the Malmö Diet and Cancer Study.
- To enable future research on diet, gene-environment interactions, and cancer.
- To support biomarker discovery and development.
Main Methods:
- Development of stringent quality control procedures for specimen banking.
- Collection and storage of purified viable mononuclear leucocytes, granulocytes, erythrocytes, plasma, and serum.
- Storage of tumor and normal tissues from cancer cases.
Main Results:
- Established adequate banking procedures for assessing dietary intake variables (e.g., vitamins, lipids, micronutrients).
- Procedures accommodate non-dietary variables (e.g., immunologic, ecogenetic factors) and gene-environment interactions.
- Ensured quality control for all stored biological specimens.
Conclusions:
- The developed biobanking procedures are suitable for future biomarker research in diet and cancer.
- This initiative is expected to stimulate significant activity in biomarker development.
- Facilitates investigation of gene-environment interactions in cancer etiology.
