[Study of p53 protein expression in cancers of small intestine and its relationship to clinical course and prognosis].
In order to study the relationship of p53 gene mutation with the occurrence and prognosis of cancer of small intestine, expression of p53 protein was examined. The results showed that p53 protein expression was high in 75% of small intestine cancer, and 21.1% positive in tissues close to cancer. In 7 cases of small intestinal adenoma only one was positive. Sixteen cases of normal tissue of intestine showed negative expression of p53 protein. The study also found that the degree of p53 protein expression was significantly correlated with the degree of tumor cell differention, invasion, metastasis and prognosis.
