Metastatic tumors to the upper gastrointestinal tract: endoscopic experience.
Metastatic tumors to the upper gastrointestinal tract were identified by esophagogastroduodenoscopy in 14 patients. Malignant melanoma, breast cancer, and lung cancer were the most common primary cancers in four, three, and three patients, respectively. Osteogenic sarcoma, renal cell carcinoma, Meckel cell carcinoma of the skin, and germ-cell tumor were the primary cancer in the remaining four. The esophagus was involved in three patients, the stomach in 13, duodenum in four, and papilla of Vater in one. Upper gastrointestinal bleeding and anemia were the most common presenting features. There was correlation between symptoms and endoscopic findings in all patients. Involvement of gastrointestinal tract at endoscopy was the initial and only evidence of metastases in all patients without evidence of metastases elsewhere, as evidenced by other diagnostic tests in any of these patients. Endoscopic biopsies and/or brush cytology provided histologic diagnosis in all 14 patients. The endoscopic and nonendoscopic literature regarding metastases to the upper gastrointestinal tract is reviewed.
