A Case of Gastric Neuroendocrine Carcinoma with Disseminated Recurrence 14 Years after Initial Surgery.

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
introductionGastric neuroendocrine carcinoma (NEC) is a rare disease among gastric cancers, accounting for only 0.1%-0.6% of all cases. This disease is known to have a poor prognosis and a higher risk of recurrence compared to conventional gastric adenocarcinoma. CASE PRESENTATION: At the age of 44, a 60-year-old female underwent a laparoscopic-assisted proximal gastrectomy for gastric cancer at a previous hospital. Neuroendocrine carcinoma was diagnosed following a postoperative pathological examination based on histological findings and immunostaining results. The patient was followed up without any recurrences. After 14 years, a follow-up contrast-enhanced CT revealed a 9-mm mass on the greater curvature side of the gastric antrum, which was suspected to be lymph node swelling at the previous hospital. After 8 months, she came to our hospital with abdominal discomfort and distention. The CT scan revealed a 55-mm mass, indicating an increase in the previously mentioned mass. At our hospital, the patient underwent open tumor resection. The pathological findings revealed a recurrence of gastric NEC. The patient has been recurrence-free for 6 months following surgery.
conclusionsWe present a case of gastric NEC with disseminated recurrence. To our knowledge, this is the first report of a disseminated case in which a recurrent lesion caused by omental dissemination grew in size and infiltrated a portion of the gastric serosa approximately 14 years after the initial surgery.
