Abstract
BACKGROUND
Lung cancer is the most prevalent malignant tumor in human body, and is characterized by a high level of malignancy. The most common metastatic sites include the liver, bone, brain, and adrenal gland, while lung cancer resulting in gastrointestinal tract metastasis is uncommon.
CASE SUMMARY
A 74-years-old man with lung cancer was hospitalized owing to blood in the stool, The cause was identified as metastasis to the small intestine, and the patient subsequently underwent radical resection of the small intestine tumor. Currently, the overall condition of the patient is good, and undergoing combined chemotherapy.
CONCLUSION
Early intervention in patients with metastatic tumors can significantly improve prognosis.
Core Tip: This article introduces a case of lung cancer with small bowel metastasis and gastrointestinal bleeding, which is relatively rare compared with other sites, and the patient underwent laparoscopic radical resection of small bowel cancer, and the long-term prognosis still needs to be observed and followed. We look forward to providing a helpful clinical experience based on this case, and there is an urgent need to record more cases to support more advanced research efforts aimed at improving the detection rate of these patients and ultimately improving the quality of life and survival of patients.
