Which one of the following tumors does not cause bony metastasis
Correct Answer: Gastric carcinoma
Description: Ref Robbins 9/e p1207 The depth of invasion and the extent of nodal and distant metastasis at the time of diagnosis remain the most powerful prognostic indicators for gastric cancer. Local invasion into the duodenum, pancreas, and retroperitoneum also is char- acteristic. When possible, surgical resection remains the preferred treatment for gastric adenocarcinoma. After sur- gical resection, the 5-year survival rate for early gastric cancer can exceed 90%, even if lymph node metastases are present. By contrast, the 5-year survival rate for advanced gastric cancer remains below 20%, in large pa because current chemotherapy regimens are minimally effective. Because of the advanced stage at which most gastric cancers are discovered in the United States, the overall 5-year survival is less than 30%.
