14. SERUM VALUES OF ALKALINE PHOSPHATASE AND LACTATE DEHYDROGENASE IN OSTEOSARCOMA
ABSTRACT Objective: To study the relationship between the pre and post chemotherapy (CT) serum levels of alkaline phosphatase (AP) and lactate dehydrogenase (LDH), and the percentage of tumor necrosis (TN) found in specimens after the pre surgical CT in patients with osteosarcoma. Methods: Series of cases with retrospective evaluation of patients diagnos

15. Nanofibrous Scaffolds for Tissue Engineering Applications
The discipline of tissue engineering opens up the ways for repair and regenerate damaged organs and tissues. In the current work biomimetic nanofibrous scaffolds were fabricated by electrospinning. Poly-L-lactic acid (PLLA) was blended with collagen and gelatin to fabricate PLLLA-collagen and PLLA-gelatin fibrous scaffolds respectively. Pure PLLA and gelatin

17. Correlation between the expression of vegf and survival in osteosarcoma
Objective: To present a series of 50 consecutive patients with non-metastatic extremity osteosarcoma, and attempt to correlate expression of the vascular endothelial growth factor (VEGF) protein in biopsy tissue to their prognosis regarding overall survival, disease-free survival and local recurrence. Methods: Fifty cases of non-metastatic osteosarcoma

18. Postural assessment of patients with non-conventional knee endoprosthesis
Objective: To investigate the correlation between the sagittal and frontal alignment and possible postural asymmetries found in patients submitted to total knee stent placement for osteosarcoma. Methods: Twenty two individuals were divided into two groups according to tumor location: femur group (13 patients) and tibia group (nine patients), who were e

19. Aggressive Multilocular Osteoblastoma in the Mandible: A Rare and Difficult Case to Diagnose
O osteoblastoma é uma neoplasia benigna e incomum nos maxilares. Em alguns casos esta lesão apresenta características locais extremamente agressivas, sendo denominada osteoblastoma agressivo. Devido às características clínicas, radiográficas e histopatológicas serem similares a uma variedade de tumores benignos e malignos, o seu diagnóstico é um di

20. Expressão imuno-histoquímica das proteínas VEGF e HER-2 em biópsias de osteossarcoma
OBJETIVOS: Identificar a prevalência de HER-2 e do fator de crescimento do endotélio vascular (VEGF) em biópsias de osteossarcoma e correlacioná-los com possíveis fatores de prognóstico. MÉTODOS: Estudo retrospectivo realizado no Hospital de Câncer de Barretos-SP incluindo 27 biópsias de osteossarcoma imuno-histoquimicamente coradas para VEGF e HER-

21. Primary tumorectomy promotes angiogenesis and pulmonary metastasis in osteosarcoma-bearing nude mice
PURPOSE: To investigate the effect of primary tumorectomy on angiogenesis and pulmonary metastasis in osteosarcoma-bearing nude mice. METHODS: Osteosarcoma was introduced to nude mice via subcutaneous injection of MG-63 cells. One hundred and eighty osteosarcoma-bearing mice were used equally in 3 parallel experiments. The effect of tumorectomy (TR) on the e

22. Avaliação dos fatores prognósticos e sobrevida de pacientes com Osteossarcoma atendidos em um Hospital Filantrópico de Teresina (PI), Brasil
OBJECTIVE: Make an analysis of the factors that influence their survival and prognosis of patients with osteosarcoma treated at a Charity Hospital in Teresina-PI. METHODS: We analyzed medical records of 32 patients diagnosed with osteosarcoma in the period January 2005 to December 2010. RESULTS: Patients were aged between 6 and 73 years, with 56.

24. Análise molecular dos genes HRPT2 e CICLINA D1 na displasia fibrosa, no fibroma ossificante e no osteossarcoma dos maxilares
Fibrous dysplasia (FD), ossifying fibroma (OF), and osteosarcoma (OS) are examples of bone-related lesions. Recent studies have already shown genetic alterations of the HRPT2 tumor suppressor gene in sporadic and syndromic OF. The present study first sought to raise the hypothesis of whether or not similar alterations would in fact represent one of the under
