BACKGROUND Controversy has surrounded the role of isolated limb perfusion (ILP) for unresectable extremity sarcomas. However, there remains a group of sarcoma patients for whom amputation is the only potential treatment. Because systemic therapies are limited, the authors evaluated ILP in an effort to provide a limb-salvage option. METHODS Since 1995,(More)
The catabolic response to sepsis, severe injury, and burn is characterized by whole-body protein loss, mainly reflecting increased breakdown of muscle proteins, in particular myofibrillar proteins. Glucocorticoids and various proinflammatory cytokines are important regulators of muscle proteolysis in stressed patients. There is evidence that breakdown of(More)
Recent studies suggest that the skeletal muscle may be a significant site of IL-6 production in various conditions, including exercise, inflammation, hypoperfusion, denervation, and local muscle injury. The mediators and molecular mechanisms regulating muscle IL-6 production are poorly understood. We tested the hypothesis that IL-6 production in muscle(More)
BACKGROUND Racial disparities exist for patients with pancreatic cancer. This observation has primarily been noted in the Surveillance, Epidemiology, and End Results database and has focused primarily on whites and African Americans. We sought to determine if these disparities exist in a local, racially diverse patient population. METHODS Retrospective(More)
BACKGROUND Abdominal pain in neutropenic cancer patients presents a unique clinical challenge for surgeons. The purposes of this retrospective study were to characterize the clinicopathologic factors associated with the presentation of neutropenia and abdominal pain, examine the treatment strategies used, and define associated outcomes for these patients.(More)
BACKGROUND Disparities in colon cancer survival have been reported to result from advanced stage at diagnosis and delayed therapy. We hypothesized that delays in treatment among medically underserved patients occur as a result of system-level barriers in a safety-net hospital system. MATERIALS AND METHODS Retrospective review and analysis of colon cancer(More)
Sepsis-induced muscle cachexia is associated with increased expression of several genes in the ubiquitin-proteasome proteolytic pathway, but little is known about the activation of transcription factors in skeletal muscle during sepsis. We tested the hypothesis that sepsis upregulates the expression and activity of the transcription factors CCAAT/enhancer(More)
Pancreatic duct carcinoma remains a common disease with a poor prognosis. More than 30,000 Americans will die of the disease in 2004, making it the fourth leading cause of cancer death. Despite significant advances in the treatment of many other human tumors, the 5-year survival rate for persons diagnosed with pancreatic cancer has not changed in decades(More)
BACKGROUND For patients who suffer from severe chronic pancreatitis, total pancreatectomy can alleviate pain, and islet autotransplantation (IAT) might preserve endocrine function and circumvent the complications of diabetes. Factors that determine success after this operation have not been clearly defined. STUDY DESIGN From 2000 to 2004, 45 total or(More)
Muscle wasting during sepsis reflects increased expression and activity of the ubiquitin-proteasome proteolytic pathway and is at least in part mediated by glucocorticoids. The ubiquitination of proteins destined to be degraded by the proteasome is regulated by multiple enzymes, including ubiquitin ligases. We tested the hypothesis that sepsis upregulates(More)
