Accuracy of computerized tomography in determining hepatic tumor size in patients receiving liver transplantation or resection.

چکیده
Computerized tomography (CT) of liver is used in oncologic practice for staging tumors, evaluating response to treatment, and screening patients for hepatic resection. Because of the impact of CT liver scan on major treatment decisions, it is important to assess its accuracy. Patients undergoing liver transplantation or resection provide a unique opportunity to test the accuracy of hepatic-imaging techniques by comparison of findings of preoperative CT scan with those at gross pathologic examination of resected specimens. Forty-one patients who had partial hepatic resection (34 patients) or liver transplantation (eight patients) for malignant (30 patients) or benign (11 patients) tumors were evaluable. Eight (47%) of 17 patients with primary malignant liver tumors, four (31%) of 13 patients with metastatic liver tumors, and two (20%) of 10 patients with benign liver tumors had tumor nodules in resected specimens that were not apparent on preoperative CT studies. These nodules varied in size from 0.1 to 1.6 cm. While 11 of 14 of these nodules were less than 1.0 cm, three of 14 were greater than 1.0 cm. These results suggest that conventional CT alone may be insufficient to accurately determine the presence or absence of liver metastases, extent of liver involvement, or response of hepatic metastases to treatment.

Metastatic tumors to the liver resulting in fulminant hepatic failure are a rare occurrence and have not been previously described in patients with gastrointestinal stromal tumor (GIST). A 70 year-old man was referred to hospital with postprandial discomfort. On examination a 19.5 cm large epithelioid GIST of the stomach was diagnosed. The mass exhibited unfavorable prognostic features: mitotic...

RATIONALE The shortage of available donor organs limits the development of liver transplantation. This case-serial study presents a novel way to expand the donor pool by using the other-wise discarded partial liver resection graft with hepatic benign tumor. PATIENT CONCERNS From 2012 to 2016, 15 patients with hepatic lesions were admitted to our hospital. 12 patients suffered from right epiga...

Background. Hepatic epithelioid hemangioendothelioma is a rare malignant tumor of vascular origin with frequent multifocal appearance. Liver resection may cause tumor spread. Liver transplantation has been indicated for unresectable nodules. We hypothesized that adjuvant interferon treatment is effective to prevent metastasis after liver resection. We report a case of multifocal hepatic epithel...
