An observational study in Colorectal Cancer (CRC) and Specimens Are to be Collected From Subjects Who Are Having or Have Had a Fluid or Tissue Removed, a Biopsy or a Blood or Bone Marrow Draw, sponsored by hui hou. Completed at 1 site in China. Per ClinicalTrials.gov, last updated 2025-09-29.
Sponsored by hui hou · Observational
Collect some tumor tissue specimens from patients who have undergone colorectal cancer surgery and conduct experiments such as immunohistochemistry to observe the expression of related genes in colorectal cancer.
We need to collect postoperative specimens and adjacent normal tissue specimens from patients with colorectal cancer for immunohistochemical staining. There is no need to conduct any other grouping of the patients.
5,599 studies on the registry are indexed under Colorectal Neoplasms; 1,459 are open to participants now.
