Solitary anterior mediastinal lymph node metastasis with pericardial invasion from colon cancer: A case report.

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
Colorectal cancer commonly metastasizes to the regional lymph nodes, liver, lungs and peritoneum. At present, mediastinal lymph node metastasis from colorectal cancer is uncommon and poorly understood. The present study reported a case of solitary anterior mediastinal lymph node metastasis with pericardial invasion from transverse colon cancer. An 82-year-old woman had a history of colectomy with regional lymph node dissection for transverse colon cancer (T1N1bM0 stage IIIA in the UICC classification). The patient had no symptoms, but follow-up contrast-enhanced computed tomography revealed an anterior mediastinal tumor compressing the heart 18 months after colectomy. The tumor showed fluorodeoxyglucose uptake on positron emission tomography. Resection of the anterior mediastinal tumor with pericardiectomy was performed. The tumor was 35x25 mm in size and was histopathologically characterized to be adenocarcinoma. These cells expressed cytokeratin (CK)20 and caudal-type homeobox protein 2 but not CK7 and thyroid transcription factor 1 on immunohistochemical analysis, confirming a diagnosis of metachronous mediastinal metastasis originating from colon cancer. The tumor cells invaded the adjacent pericardium and diaphragm pathologically. The patient has lived without recurrence 8 months after the surgery for mediastinal metastasis. In conclusion, clinicians should consider metastasis to the mediastinum during follow-up in patients with colorectal cancer. Surgery may be the most reliable treatment for solitary anterior mediastinal lymph node metastasis, preventing carcinomatous pericarditis through direct pericardial invasion.
