Abstract:
The degree of medullary infiltration by plasmocytes has a prognostic value which completes the clinical classifications proposed in multiple myeloma. Beyond a 50 p. cent medullary infiltration, the mean survival of the patients is significantly shorter (p less than 0.02) than survival of patients presenting less than 50 p. cent medullary infiltration. The degree of medullary infiltration is unrelated to the stage of Durie and Salmon classification, but is correlated to the degree of differentiation of the plasmocytes.
