I have established the tissue biobank, biorepository, and database of colorectal cancers and premalignant neoplasms for population-based cohort studies.
We aim to contribute to better understanding of pathogenesis, and disease prevention and treatment.
We focus on colorectal cancer and precursors (colon carcinoma, rectal carcinoma, adenocarcinoma, colon cancer, rectal cancer, anal cancer, aberrant crypt foci, hyperplastic polyp, sessile serrated adenoma, sessile serrated polyp, traditional serrated adenoma, tubular adenoma, tubulovillous adenoma, villous adenoma, high-grade dysplasia, intramucosal carcinoma, hamartoma, hamartomatous polyp, neoplasm, neoplasia, mixed polyp, etc.).
I served as an Advisor of Lower GI Panel of American Joint Commission on Cancer (AJCC) which makes colon and rectal cancer staging system. Revised AJCC staging manual has been published (2017).
I also served as a member of ASCP/CAP/AMP Molecular Testing for Colorectal Cancer Biomarkers Advisory Panel, and a member of Biospecimen Advisory Group of American Cancer Society (ACS). I was a member of National Comprehensive Cancer Network (NCCN) Task Force: Evaluating the Clinical Utility of Tumor Markers in Oncology. Molecular testing guidelines have been published (Sepulveda A et al. J Mol Diagn 2017).
