"Análise imunohistoquímica do osteossarcoma em pacientes com e sem metástases e sua correlação prognóstica" / Immunohistochemistry analysis of osteosarcoma in patients with and without metastasis and its prognosis correlation

Abadi, Marcia Datz 06 December 2005 (has links)
As proteínas p53, MDM-2, c-Kit, ErbB-2, PCNA e p-glicoproteína foram estudadas em 42 amostras de osteossarcoma ao diagnóstico, através da técnica de imunohistoquímica, e foram correlacionados estes achados com o prognóstico destes pacientes. O p-53 foi positivo em 23,1% (9/39), PCNA em 71,4% (25/35), p-glicoproteína em 40,5% (15/37), MDM-2 em 34,8% (8/23), c-kit em 67,6% (25/37) e ErbB-2 em 17,9% (7/39). Na análise univariada, a presença de metástases ao diagnóstico, a positividade de p53 e ErbB-2 influenciaram o prognóstico individualmente, entretanto, na análise multivariada, a presença de metástase ao diagnóstico revelou-se o único fator de prognóstico estatisticamente significante / We study, by imunohistochemistry technique, the proteins p53, MDM-2, c-Kit, ErbB-2, PCNA and p-glycoprotein in samples of osteosarcoma tumors at diagnosis and its correlation with the prognosis of this patients. The p-53 was positive in 23,1% (9/39), PCNA in 71,4% (25/35), p-glycoprotein in 40,5% (15/37), MDM-2 in 34,8% (8/23), c-kit in 67,8%(25/37) and ErbB-2 in 17,9% (7/39) of the samples. In the univariate analysis, the presence of metastasis at diagnosis, the positivity of p-53 and ErbB-2 influenced the prognosis individually, otherwise, in the multivariate analysis, the presence of metastasis at diagnosis was the only prgnostic factor statistically significant
