Prognostic significance of bone marrow micrometastases in patients with gastric cancer.

Abstract

Presence of disseminated tumor cells in bone marrow is indicative of systemic disease even in early-stage gastric cancer. The extent of tumor-cell presence in bone marrow correlates with prognosis in curatively resected patients. Therefore, a positive bone marrow finding may be a selection criteria for adjuvant treatment because of minimal residual tumor load.
