title: [Reproducibility of a mathematical model for calculating survival in multiple myeloma].
abstract: The reliability of the mathematical model for calculating survival proposed by Merlini, Waldenstrom e Jayakar (1980) was tested in a group of 80 patients with multiple myeloma. The observed and calculated survivals were compared using univariate regression analysis. The results show that a significant (p less than 0.001) relationship between observed and calculated survival exists in the study patient group. These observations confirm that this useful and reliable clinical staging system can be a basis for individualization of a new treatment approach for each stage in order to reach an optimal treatment for multiple myeloma patients.
