Background: Patients with hepatocellular carcinoma (HCC) beyond the Milan criteria are expected to have inferior outcome after liver transplantation (LT) and are therefore currently not considered for LT in many countries. The purpose of this study was to identify predictive factors for overall survival following LT for HCC that may support the Milan criteria in the selection of appropriate transplant candidates.
Methods: Clinicopathological data on 364 patients with HCC who underwent LT between 1989 and 2010 were retrospectively evaluated.
The impact of simultaneous liver resection for occult liver metastases of pancreatic adenocarcinoma.
Gastroenterol Res Pract
December 2012
Article Synopsis
- Pancreas resection is the only curative option for pancreatic adenocarcinoma, but patients with incidental liver metastases were usually referred to palliative care.
- This study examined 22 patients who underwent simultaneous pancreas and liver resections for hepatic metastasized pancreatic adenocarcinoma (HMPA) and compared their outcomes to 22 patients who had classic pancreas resections for nonmetastasized pancreatic adenocarcinoma (NMPA).
- While postoperative complications and operation times were similar between groups, the overall survival rate was significantly lower for the HMPA group, suggesting that more research is needed to determine if this surgical approach benefits patients in terms of survival or quality of life.
A method for pseudocolor encoding of a black-and-white transparency is performed through the simultaneous addition of a direct contrast image, a pseudoreversed image, and a reversed contrast image, each in a different primary color: blue, green, and red, respectively. The physical bases of the method are both specular and diffuse densities, and the method works in real time. The addition of these three color images increases the appreciation range of gray levels in a zone pattern, thereby providing a significant improvement in the information display.
