[Bone metastasis of gastric cancer].

We evaluated 19 patients with bone metastasis after surgery for gastric cancer. In a number of cases, the located in the tumor was U and M region, of macroscopic 3, and the histological type was poorly-differentiated adenocarcinoma with high-grade of lymphatic invasion. The major symptom was lumbago and back pain. The serum AFP level was high in 73.7% of the cases, and LDH was high in 47.7%. The metastatic lesion was predominantly seen in the bone with red pulp such as lumbar and thoracic vertebra and rib. The median survival time was 189 days (range: 24-509) with a poor prognosis. However, newly developed anticancer drugs were very effective for some cases, indicating that such chemotherapy should be tried for cases with bone metastasis.
