Circulating Breast Carcinoma Cells Mimicking Therapy-Related Acute Myeloid Leukemia.

abstract：:Studies on the expression of beta-catenin (beta-ct) in gastric carcinoma have provided conflicting results, and the role played by beta-ct mutations in gastric carcinogenesis remains unclear. In an attempt to clarify the aforementioned issues we undertook the retrospective study of 157 gastric carcinomas by using immu...
