Heterochronic gastric adenosquamous carcinoma combined with colonic adenoma: A case report.
Article in World journal of gastrointestinal oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMetachronous gastric cancer usually refers to a tumor that occurs in the stomach more than half a year after esophageal cancer surgery, and metastasis of primary esophageal cancer should be excluded. There are few reports of metachronous gastric adenosquamous carcinoma with signet ring cell carcinoma combined with early tubular adenoma of the colon after esophageal cancer surgery, which has a high degree of malignancy. This is also the reason for the poor treatment results. CASE SUMMARY: A 54-year-old male patient was admitted to the hospital with "dysphagia obstruction". Seven years ago, the patient was diagnosed with well-differentiated squamous cell carcinoma in the middle esophagus (T4N1M0 stage) and left gastric lymph node metastasis. In the final resection of the esophageal cancer, no residual cancer tissue was found in the esophageal and gastric stump. The patient's medical history 7 years ago (preoperative gastroscopy and other examinations) revealed no gastric tumor. Combined with the patient's history, the diagnosis of recurrent esophageal cancer was made on this admission. The final pathological results were surprising: Metachronous gastric adenosquamous carcinoma with signet ring cell carcinoma combined with early tubular adenoma of the colon. Considering the high malignancy of the tumor, the complexity of the second operation, and many complications, the patient received chemotherapy.
conclusionHe had a history of esophageal cancer resection. Gastroenteroscopy should be performed simultaneously to avoid missed diagnosis and misdiagnosis.
