Survivin is a novel inhibitor of apoptosis. It is detected in fetal and neoplastic adult tissue, but not in normal tissues. Several recent studies have shown that survivin not only inhibits apoptosis, but also accelerates cancer cell proliferative activity. Expression of the protein may be of prognostic significance and therapeutic relevance in many cancers. We investigated survivin expression in hepatocellular carcinoma, correlating results with proliferation (MIB-1), prognostic factors, and outcome. Paraffin-embedded sections of 72 hepatocellular carcinoma were immunostained for survivin and MIB-1 using tissue microarray technology. Expression was evaluated in nuclei and cytoplasm as intensity (0-3 þ ), and percentage of positive cells scored on a four-tiered system with less than 10% ¼ negative; 10-25% ¼ 1; 26-50% ¼ 2; 51-75% ¼ 3; and 76-100% ¼ 4. Frequency of nuclear survivin expression was 43%. There was a significant correlation between nuclear survivin expression and nuclear grade (P ¼ 0.0271), microvascular invasion (P ¼ 0.0064), mitotic rate (P ¼ 0.0017), and MIB-1 (P ¼ 0.0001), as well as local recurrence (P ¼ 0.0487), and disease-free survival (P ¼ 0.0098). Histologic grade (P ¼ 0.0544) and stage (P ¼ 0.0548) tended to correlate with survivin expression, which did not correlate with cirrhosis, tumor necrosis, multiple tumors, metastatic disease, or overall survival. Survivin expression correlates with poor prognostic parameters (high nuclear and histologic grade, microvascular invasion, increased proliferation (mitotic count, MIB-1)), local recurrence, and shorter diseasefree survival, but does not correlate with overall survival. An important role is suggested for survivin in progression, recurrence, and treatment of hepatocellular carcinoma.
Hereditary hemochromatosis (HIT), an autosomal recessive disease of iron overload, is one of the most common inherited diseases. The candidate gene (HFE) for HH lias been identified recently and a DNA- based test for the mutation is available. Treatment for HH patients with elevated iron stores include repeated phlebotomy. Left untreated, iron overload can lead to cirrhosis, organ failure, and a shortened life expectancy. In the past and present, blood collected for therapeutic purposes from patients with HH has been discarded. The aim of this article is to address whether blood collected from HH patients should be used for allogeneic transfusion in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
