Core Tip

Core tip: In this nationwide retrospective autopsy study, the metastatic pattern of 599 patients with metastases of primary adenocarcinoma or squamous cell carcinoma of the esophagus or stomach were evaluated. Differences in metastatic patterns of these patients were found according both to the primary tumor location as well as the histological subtype. This study provides robust data regarding metastatic patterns in esophageal and gastric cancer patients. Knowledge of metastatic patterns is helpful during preoperative staging, follow-up and in future research.
