PURPOSE Life expectancy is routinely used as part of the decision-making process in deciding the value of surgery for the treatment of bone metastases. We sought to investigate the validity of frequently used indices in the prognostication of survival in patients with metastatic bone disease. METHODS The study prospectively assessed 191 patients who(More)
BACKGROUND Limb salvage following resection of a tumor in the proximal part of the humerus poses many challenges. Reconstructive options are limited because of the loss of periarticular soft-tissue stabilizers of the glenohumeral joint in addition to the loss of bone and articular cartilage. The purpose of this study was to evaluate the functional outcome(More)
BACKGROUND Local recurrence in osteosarcoma is clinically distinct from metastasis, although associated with a similar reduction in survival. The prognostic factors in locally recurrent osteosarcoma were investigated and these factors were translated into a management strategy. METHODS In all, 407 consecutive patients with skeletal osteosarcoma between(More)
BACKGROUND Pathologic proximal femur fractures result in substantial morbidity for patients with skeletal metastases. Surgical treatment is widely regarded as effective; however, failure rates associated with the most commonly used operative treatments are not well defined. QUESTIONS/PURPOSES We therefore compared surgical treatment failure rates among(More)
Activation of the endothelin A receptor (ET(A)) by endothelin-1 (ET-1) mediates events that regulate mitogenesis, apoptosis, angiogenesis and metastasis in tumours. Specific blockade of ET(A) may have anticancer effects, while retaining beneficial endothelin B receptor (ET(B))-mediated effects such as apoptosis and clearance of ET-1. ZD4054 is an orally(More)
BACKGROUND The pelvis is an infrequent site of osteosarcoma and treatment requires surgery plus systemic chemotherapy. Poor survival has been reported, but has not been confirmed previously by the Children's Oncology Group (COG). In addition, survival of patients with pelvic osteosarcomas has not been compared directly with that of patients with nonpelvic(More)
UNLABELLED The treatment of primary osteogenic sarcoma is well established in younger patients; however, controversy surrounds the treatment of this disease in the older population. To confirm multimodality therapy results in longer survival than surgery alone, 58 patients older than 40 years with primary osteogenic sarcoma were assessed retrospectively for(More)
The tear film is complex and is rich in both peptides and proteins. Physiological factors have been shown to alter the balance of the protein components in the tear film, however, little is known of the precise stimuli that initiate these changes, or their nature and extent. Attention has been directed at the role of tear proteins in the protection of the(More)
PURPOSE To adapt membrane-bound antibody array (MA) technology to characterize the distribution of a wide range of bioactive trace proteins in reflex (RTF) and open-eye (OTF) and closed-eye (CTF) tear samples. METHODS Tears were collected by capillary tube and centrifuged. A commercially available standard MA and a custom array were modified to maximize(More)
BACKGROUND Compliant, self-adjusting compression technology is a novel approach for durable prosthetic fixation of the knee. However, the long-term survival of these constructs is unknown. QUESTIONS/PURPOSES We therefore determined the survival of the Compress prosthesis (Biomet Inc, Warsaw, IN, USA) at 5 and 10 actuarial years and identified the failure(More)
