Intestinal Metastasis of Choriocarcinoma: A Case Report of a Rare Cause of Gastrointestinal Bleeding.

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
Choriocarcinoma is widely known as an aggressive gestational trophoblastic disease characterized by rapid proliferation and early hematogenous spread. Gastrointestinal metastases, particularly to the small intestine, are rare but can lead to life-threatening complications such as ulceration, perforation, and massive bleeding. This case report describes intestinal metastasis of choriocarcinoma in a 30-year-old patient presenting with chronic hematochezia, progressive pallor, unintentional weight loss over three months, and left lower abdominal pain. Previously, the patient had a molar pregnancy, which was removed via dilation and curettage procedure, but no subsequent follow-up and examinations were conducted post-operation. Physical examination revealed conjunctival pallor and a palpable mass in the left lower quadrant, with rectal examination confirming active bleeding. Chest X-ray revealed multiple pulmonary nodules, and ultrasound revealed abdomen liver metastasis and irregular mass in the lower abdomen. The same mass was confirmed by CT scan of the abdomen. During hospitalization, the patient experienced recurrent GI bleeding, necessitating multiple blood transfusions. Colonoscopy identified an actively bleeding mass in the terminal ileum, and an abdominal CT scan confirmed a large abdominal mass. Extremely elevated levels of hCG (>1,000,000 mIU/mL) supported the diagnosis of metastatic gestational trophoblastic cancer with subsequent histopathological analysis confirmed metastatic choriocarcinoma. Given the persistent hemorrhage, surgical intervention was performed, but the patient developed postoperative sepsis and succumbed to the illness. Although choriocarcinoma is highly treatable with chemotherapy, atypical metastases to the gastrointestinal tract can complicate diagnosis and management, leading to severe complications. This case emphasizes the importance of considering choriocarcinoma in the differential diagnosis of unexplained GI bleeding in patients with a history of gestational trophoblastic disease.
