Metastatic de novo lung cancer presenting as acute jejunojejunal intussusception: an unusual case report.
Article in Discover oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSmall bowel metastasis from primary lung cancer is a rare occurrence, and jejunojejunal intussusception secondary to metastatic lung cancer is even rarer. CASE PRESENTATION: We report the case of a 56-year-old Caucasian man diagnosed with metastatic adenosquamous carcinoma of the lung who presented with jejunojejunal intussusception secondary to small bowel metastasis from his lung cancer. He underwent emergency segmental resection. Histological examination of the specimen revealed metastasis originating from the adenocarcinomatous component of the lung adenosquamous carcinoma. Unfortunately, the patient was lost to follow-up during palliative chemotherapy.
conclusionThis case highlights the importance of considering intussusception caused by gastrointestinal metastases in the differential diagnosis of patients with lung carcinoma presenting with abdominal pain or other gastrointestinal symptoms. Surgical intervention is often necessary in such cases. Intussusception indicates a poor prognosis in patients with lung carcinoma, regardless of the management strategy employed.
