Core Tip

Core Tip: The clinical metastasis rate of lung cancer in gastrointestinal tract is extremely low, and patients with small intestine metastasis of lung cancer have worse prognosis and shorter survival than those with metastasis in other parts of the body. As a result, early diagnosis and development of systematic treatment for patients with gastrointestinal metastasis in lung cancer are crucial. Aside from that, individuals enduring lung cancer who experience acute abdominal symptoms should be aware of the possibility of small intestinal metastasis. We report a rare case of small intestine metastasis from lung adenocarcinoma in terms of diagnosis, treatment, and prognosis.
