title: Metastatic mode of gastric carcinoma by flow cytometric and clinicopathologic parameters.
abstract: We used flow cytometric and conventional clinicopathologic parameters to analyse the metastatic mode of cancer in 113 stomach cancer patients. Liver metastasis was frequent in cases with intestinal-type cancer, cancer located in the distal stomach, positive venous invasion and aneuploid cancer. Lung and pleural metastasis (excluding nodular lung metastasis), however, were frequent in cases with serosal invasion and diploid cancer. Peritoneal metastasis was frequently seen with tumors located in the proximal or whole stomach, diffuse-type cancer and cancer with serosal invasion. All cases developing bone metastasis were positive for lymph node metastasis. DNA ploidy was partially related to the metastatic mode of stomach cancer, but this was not the sole parameter for predicting metastasis. However, prediction may be possible if based on both DNA ploidy and clinicopathologic parameters, suggesting the possibility of the prophylaxis of recurrence by appropriate postoperative adjuvant therapy.
