摘要: BACKGROUND. This study was undertaken to evaluate whether genetic analysis in the stool can be useful for detecting malignant tumors colon and rectum. We searched possible presence of mutations p53 gene patients with resectable colorectal cancer. Alterations are most frequent among mutant genes related METHODS. Surgically resected tumor specimens samples from 25 cancer were examined exons 5-8 by polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP). Results compared those achieved fecal occult blood testing. RESULTS. Mutations found tissues 11 (44%). Of these patients, 7 (64%) had evidence alterations within stool. five who negative testing, evident three patients. CONCLUSIONS. method DNA tumor-specific is expected have a wide application clinical screening
