Detection of bone marrow micrometastasis in esophageal cancer patients by immunomagnetic separation.

Detection of micrometastasis to the bone marrow can predict widespread disease and a poor prognosis of cancer patients. The purpose of this study was to evaluate the clinical significance of detecting micrometastasis in the bone marrow of esophageal cancer patients. Bone marrow and peripheral blood samples were obtained from 52 squamous esophageal cancer patients at the time of surgery.

Detection of bone marrow micrometastasis in gastric cancer patients by immunomagnetic separation.
