ABSTRACT
Objective. To evaluate the impact of different prognostic
factors that has been suggested to be useful in predicting the
survival of patients with multiple myeloma (MM).
Materials
and methods. A longitudinal prospective study was conducted
on 24 adult Mexican patients diagnosed with primary MM.
The levels of expression of CD38, CD138 and cyclin D1 were
analyzed in plasma cells (PCs) from patients and mononuclear
cells from healthy donors. Serum levels of lactate dehydrogenase,
creatinine, calcium, β
2 microglobulin and
interleukin-6 (IL-6) as well as hemoglobin and platelet count
were taken into consideration.
Results. CD138 and cyclin D1
levels in absolute numbers were significantly overexpressed in
malignant PCs. A positive correlation was noted between
cyclin D1 and CD38 expression levels in malignant PCs. IL-6
and serum calcium were also positively correlated in MM patients.
Cyclin D1 overexpression was not associated with better
overall survival (OS). Normal calcium levels were
associated with better overall survival (OS). Serum calcium
was the only variable correlating with better OS in Cox regression
analysis.
Conclusion. Serum calcium is an independent
prognostic factor of OS in a population of Mexican
patients with MM.
