Abstract:

Aim: The aim is to investigate retrospectively the association between vitamin B12 levels at the time of diagnosis and the complications including hypercalcemia and fractures in multiple myeloma patients.Material and
Method: The association between vitamin B12 level at the time of diagnosis and myeloma complications such as hypercalcemia and bone lesions were analyzed with chi-square in 140 multiple myeloma patients.Findings: Vitamin B12 deficiency was found in 29 patients (20.7%). While the rate of hypercalcemia is 37.9% in patients with vitamin B12 deficiency, it is 18.9% in patients without deficiency. The fracture rate was 44.8% in vitamin B12 deficient group and 23.4% in the other group.Results: Vitamin B12 deficiency at the time of diagnosis is associated with hypercalcemia and bone fracture rate (p=0.04, p=0.03).Discussion: Vitamin B12 level might have prognostic significance since hypercalcemia and fracture rate is increased in the vitamin B12 deficient group. Further studies with a larger patient group are needed on this subject.
