Prostate cancer metastatic to the stomach

Metastatic prostate cancer has poor prognosis, with survival rates ranging from 1 to 3 years. Frequent sites for metastases are the skeletal system and lymph nodes; metastases to the gastrointestinal tract are rare. Although most patients become symptomatic with bone or flank pain, the patient we report initially presented with severe nausea and vomiting accompanied by moderate back pain. His prostate-specific antigen level was 171 ng/mL. Computed tomography and bone scan revealed retroperitoneal lymphadenopathy and bone metastasis. Cranial computed tomography was negative for metastasis but upper endoscopy and biopsy revealed a metastatic lesion from prostate cancer. (C) 2004 Elsevier Inc.
