title: [Tumor markers--personal experience. Ha-ras P21 in neuroblastoma: a new marker associating to patient's prognosis].
abstract: Neuroblastoma is a disease with wide spectrum clinically For the evaluation of the biological specificity of this tumor, we examined the expression of Ha-ras p21. The Ha-ras p21 detected in tumor cells showed a statistically significant association with the non-progressed tumor at the diagnosis and the favourable outcome of the patients. The association of Ha-ras p21 with their clinical outcome was closer than those of N-myc amplification. However, the complementary analyses of both Ha-ras p21 and N-myc gene seemed to provide more precise informations relating the patient's care.
