[Clinical and laboratory features and prognostic implications in myeloma with and without renal impairment].

Presenting clinical and laboratory features, prognostic implications and survival in 124 multiple myeloma patients were reviewed in a retrospective study based on hospital records. The median age was 65 years. Out of all patients, 2.42% were younger than 40 years and 62.9% were 60 years and older. The main presenting clinical features were bone pain (70.16%), fatigue (31.45%), recurrent infections (9.68%) and weight loss (0.3%). Renal failure was present in 35.48% of patients. The higher means of ionised calcium, uric acid, erythrocyte sedimentation rate, M protein were correlated with the higher mean of serum creatinine. The acturial survival of myeloma patients without renal failure at 1 and 2 years was 95.08% and 89.23% respectively, while acturial survival of myeloma patients with renal failure at 1 and 2 years was 82.5% and 73.35% respectively (p<0.01). One-year survival in myeloma patients maintained on chronic hemodialysis was 68.75% while it is reported as 90.91% for myeloma patients not on dialysis (p<0.006).
