[Prognostic value of the new international staging system in multiple myeloma. Comparison with Durie-Salmon staging system].

Background: Since 1975, the Durie-Salmon staging system (D&S) has been a widely accepted prognostic classification of multiple myeloma (MM) patients. Recently, the new International Staging System (ISS) was developed using only the values of albumin and beta2-microglobulin.

Aim: To compare survival of patients with MM treated in six medical centers in Chile according to the D&S system and the new ISS.

[Clinical features and survival of Chilean patients with multiple myeloma].

Aim: To characterize clinical features, survival rate and factors related to mortality in cases with MM treated in six large medical centers in Chile.

Material And Method: Retrospective analysis of demographic data, clinical features and survival rate records of patients with MM, collected between 1998 and 2002.
