In the current study, we evaluated two female patients who developed colonic adenocarcinoma more than 10 years after gender-mismatched BM transplantation, and followingly underwent successful endoscopic mucosal resection. Materials and Methods: Fluorescent in situ hybridization (FISH) analysis was used to determine whether the tumours contained donor-derived BM cells. Results: Approximately 1.2% of the tumour cells contained Y-chromosome-positive signals, and a comparable percentage of normal colonic epithelial cells close to the tumour also contained Y-chromosome-positive signals. Conclusion: These results do not support the concept that GI cancer can originate from BM-derived cells.</style></abstract></record></records></xml>
