RESUMO
INTRODUCTION: Bone involvement in Multiple Myeloma results from increased osteoclast formation and activity that occurs in proximity to myeloma cells. The role of Alkaline Phosphatse (ALP) in this process and the diagnostic significance of plasma levels in patients with MM are unclear. AIM: To compare plasma ALP levels in patients with MM and solid cancers and metastatic lesions to the bone. RESULTS: In this observational retrospective study we enrolled 901 patients were enrolled: 440 patients (49%) with Multiple Myeloma, 461 (51%) with solid cancers. All 901 patients had bone lesions. Among patients with Multiple Myeloma, ALP values were mainly in the range of normality than those observed in patients with solid cancers and bone lesions. This difference is independent of stage, number and type of bone lesions. CONCLUSION: This study suggests that plasma ALP has a different clinical significance in MM than in other neoplasms and could be used as a discriminating marker in presence of bone lesions. In particular, lower or normal values, should suggest further investigations such as urinary and serum electrophoresis, associated with bone marrow aspirate in case of the presence of a monoclonal component, in order to confirm or exclude a MM diagnosis.

We report 6 pregnancies in 5 females with low-risk myelodysplastic syndromes (MDS) (median age at diagnosis 28 years, range 26-29) observed in the last 15 years. In 2 cases pregnancy was concomitant to the diagnosis of MDS, in the remaining 4 cases the intervals from diagnosis were 2, 3, 4 and 9 years, respectively. One patient had a foetal growth retardation corrected with steroid treatment while the remaining 5 pregnancies were uneventful. After a median time from delivery of 104 months (range 18-187) none of the patients developed acute myeloid leukemia (AML) and all are alive in stable disease. In conclusion, selected females with low-risk MDS could not be discouraged to have full term pregnancies.
