Core Tip

Core Tip: The common type of gastric cancer is adenocarcinoma, but the pathological type of gastric adenosquamous carcinoma is rare, so metachronous gastric adenosquamous carcinoma with signet ring cell carcinoma is even rarer. The metachronous tumors after esophageal cancer surgery are mostly found in the stomach, head and neck, but those occurring in the stomach and distal colon at the same time are rare.
