STUDY DESIGN A new surgical strategy for treatment of patients with spinal metastases was designed, and 61 patients were treated based on this strategy. OBJECTIVES To propose a new surgical strategy for the treatment of patients with spinal metastases. SUMMARY OF BACKGROUND DATA A preoperative score composed of six parameters has been proposed by(More)
The serine/threonine kinase Akt (also called protein kinase B) is well known as an important regulator of cell survival and growth and has also been shown to be required for cell migration in different organisms. However, the mechanism by which Akt functions to promote cell migration is not understood. Here, we identify an Akt substrate, designated(More)
Germ-line point mutations of the RET gene are responsible for multiple endocrine neoplasia (MEN) type 2A and 2B that develop medullary thyroid carcinoma and pheochromocytoma. We performed a differential display analysis of gene expression using NIH 3T3 cells expressing the RET-MEN2A or RET-MEN2B mutant proteins. As a consequence, we identified 10 genes(More)
STUDY DESIGN A retrospective review (phase 1) and prospective clinical study (phase 2). OBJECTIVES To identify independent risk factors for surgical site infection (SSI) and to evaluate the positive effect of prostaglandin E1 (PGE1) to decrease the risk of SSI in patients with spinal metastasis. SUMMARY OF BACKGROUND DATA Surgery for spinal metastasis(More)
BACKGROUND AND OBJECTIVES Metastasectomy of spinal lesions from renal cell carcinoma (RCC) is a promising strategy. However, its clinical outcome after spinal metastasectomy is unknown owing to the difficulty of curative surgical resection. This is the first study to examine the survival rates of patients who underwent metastasectomy of solitary spinal(More)
BACKGROUND CONTEXT Surgical site infection (SSI) associated with instruments remains a serious and common complication in patients who undergo total en bloc spondylectomy (TES). It is very important that the risk factors for SSI are known to prevent it. PURPOSE The purpose of the study was to identify independent risk factors for SSI after TES and(More)
Malignant mesothelioma (MM) is an aggressive neoplasm associated with asbestos exposure. We carried out genome-wide array-based comparative genomic hybridization analysis with 14 MM cell lines. Three cell lines showed overlapping homozygous deletion at chromosome 13q12, which harbored the LATS2 (large tumor suppressor homolog 2) gene. With 6 other MM cell(More)
STUDY DESIGN Matched patient cohorts using retrospective chart and radiographic review with independent clinical and radiographic follow-up were reviewed. OBJECTIVE To compare the clinical and radiographic outcomes of multilevel corpectomy and laminoplasty using an independent matched-cohort analysis. SUMMARY OF BACKGROUND DATA The treatment of choice(More)
The proneural basic-helix-loop-helix protein achaete-scute homologue 1 (ASH1) is expressed in a very limited spectrum of normal and cancerous cells in a lineage-specific manner, including normal pulmonary neuroendocrine cells and lung cancer cells with neuroendocrine features. Our previous results indicated that ASH1 may play a crucial role in the growth(More)
INTRODUCTION Mesenchymal status is related to "inherent resistance" to gefitinib or erlotinib in non-small cell lung cancer without epidermal growth factor receptor(EGFR) mutations. In addition, a recent report showed that the epithelial to mesenchymal transition (EMT) plays a role in acquired resistance to gefitinib in A549 cells, which harbor a KRAS(More)
