1 · What the graph read from it

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.

2 · The registry

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

introductionPrimary gastric carcinosarcoma is extremely rare. Herein, we report a case of primary gastric carcinosarcoma with small intestinal intraluminal metastasis. CASE PRESENTATION: The patient was a 77-year-old man who was referred to our hospital for further examination of occult fecal blood. At this time, the patient reported lightheadedness, and severe anemia was confirmed, with a hemoglobin level of 6.5 g/dL. Upper gastrointestinal endoscopy revealed a mass with bleeding spots in the middle 3rd of the stomach, which was thought to be the cause of the anemia. The patient's overall condition was poor; therefore, we decided to limit the surgery to local resection of the primary lesion as palliative treatment, with the main goal of controlling bleeding. The final pathological diagnosis was gastric carcinosarcoma. Postoperatively, the progression of anemia stopped, the patient was able to eat without any problems, and he was discharged home. However, 9 days later, the patient visited the emergency department complaining of abdominal pain. He was diagnosed with intestinal obstruction and underwent surgery. During surgery, a hard mass was palpable in the small intestine, and the lesion was resected. The pathological findings of the small intestinal mass were identical to those of the gastric tumor, and the patient was diagnosed with small intestinal intraluminal metastasis of the gastric carcinosarcoma. Eight months after surgery, pulmonary metastasis was detected by a CT scan. Chemotherapy with capecitabine and irinotecan was initiated, and tumor reduction was achieved.

conclusionsPrimary gastric carcinosarcoma may present with intraluminal metastasis of the small intestine, and clinicians should make a note of this when treating such patients.
