Abstract
BACKGROUND

Gastrointestinal tract metastasis from lung cancer is rare and compared to small cell lung cancer (SCLC), non-SCLC (NSCLC) is even less likely to metastasize in this manner. Additionally, small intestinal tumors can also present with diverse complications, some of which require urgent intervention.

CASE SUMMARY

In this report, we detail a unique case of stage IV lung cancer, where the presence of small intestine tumors led to intussusception. Subsequent to a small intestine resection, pathology confirmed that all three tumors within the small intestine were metastases from adenocarcinoma of the lung. The postoperative follow-up period extended beyond 14 mo.

CONCLUSION

In patients with stage IV NSCLC, local tumor control can be achieved with various treatments. However, if small intestinal metastasis occurs, surgical intervention remains necessary, as it may improve survival.

Core Tip: Small bowel metastases may occur in advanced lung cancer, leading to gastrointestinal obstruction and requiring aggressive surgical intervention. In such patients, survival may be improved if the gastrointestinal obstruction is relieved and the primary lung lesion can be controlled.
