Purpose: To evaluate the incidence, clinicopathological characteristics, treatment outcomes, prognostic factors, and survival of gastriccancer patients with bone metastases. Materials and Methods: Of 4,617 gastric cancer patients who were treated between 2001 and 2013, 176 patients with bone metastaseswere analyzed. Results: The incidence of bone metastasis was 3.8%. The most common histopathological subtype was adenocarcinoma (79%) withpoor differentiation (60.8%). The median interval from the diagnosis to bone metastasis was 11 months. The median survival time afterbone metastasis was 5.4 months. Factors that were associated with longer median survival times included the following: isolated bonemetastasis (P=0.004), well-differentiated tumors (P=0.002), palliative chemotherapy (P=0.003), zoledronic acid treatment (P<0.001),no smoking history (P=0.007), and no metastatic gastric cancer at the time of diagnosis (P=0.01). On the other hand, high levels oflactate dehydrogenase (LDH) (hazard ratio [HR]: 1.86; P=0.015), carcinoembryonic antigen (CEA) (HR: 2.04; P=0.002), and carbohydrateantigen (CA) 19-9 (HR: 2.94; P<0.001) were associated with shorter survival times. In multivariate analysis, receiving zoledronicacid (P<0.001) and performance status (P=0.013) were independent prognostic factors. Conclusions: Smoking history, poor performance status, poorly differentiated adenocarcinoma, and high levels of LDH, CEA, and CA19-9 were shown to be poor prognostic factors, while receiving chemotherapy and zoledronic acid were associated with prolonged survivalin gastric cancer patients with bone metastases.
