Gastrointestinal malignancies are among common cancers in humans. Surgical resection remains treatment of choice but despite surgery 45% ultimately die of distant metastasis. Detection of Disseminated Tumor Cells may provide a promising approach to improve prognosis and for changing treatment approach in patients. Our aim is to study the incidence of bone marrow micrometastasis in patients with gastric cancers and to correlate the presence of micrometastasis with other prognostic factors .We performed study in 50 patients with gastric malignancies. 9 patients (18%) showed positivity for disseminated cells in bone marrow . Depth of tumor invasion,stage and histological grade of tumor correlated statistically with presence of disseminated cells in marrow .
