21 years of evolution of primary hepatic neuroendocrine neoplasm in a patient with primary sclerosing cholangitis: 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
introduction and importancePrimary hepatic neuroendocrine neoplasms(PHNEN) are among the rarest primitive neuroendocrine neoplasms. Main prognostic factor is histological. We report an unusual case of a PHNEN with 21 years of evolution in the setting of a primary sclerosing cholangitis(PSC). CASE PRESENTATION: A 40 year old man presented in 2001 with clinical signs of obstructive jaundice. CT-scan and MRI showed a 4 cm large hypervascular proximal hepatic mass evoking hepatocellular carcinoma(HCC) or cholangiocarcinoma. Exploratory laparotomy found an aspect of advanced chronic liver disease of the left lobe. Extemporaneous biopsy of a suspicious nodule showed signs of cholangitis. Left lobectomy was performed and postoperatively the patient received ursodeoxycholic-acid and biliary stenting. After 11 years of follow-up, jaundice reappeared with a stable hepatic lesion.A percutaneous liver biopsy was done. Pathology showed a G1 neuroendocrine tumor. Endoscopy, imagery and Octreoscan were normal, supporting the diagnosis of PHNEN. PSC was diagnosed on tumor-free parenchyma. The patient is on liver transplantation waiting list. CLINICAL DISCUSSION: PHNENs are exceptional. Pathology findings, endoscopy and imagery are necessary to rule out an extra hepatic NEN with liver metastasis. While G1 NEN are known for their slow evolution, this 21 year latency is extremely rare. The presence of PSC adds to the complexity of our case. Surgical resection is recommended when possible.
conclusionThis case showcases the extreme latency of some PHNEN as well as possible overlap with PSC. Surgery is the most recognized treatment. Liver transplantation seems to be necessary for us, as the rest of the liver shows signs of PSC.
