“…Follow-up At diagnosis a complete history was obtained and the general performance and objective clinical status of the patient were assessed, together with a number of routine haematological laboratory parameters (including erythrocyte sedimentation rate, haemoglobin level, white cell count and differential, platelets, serum creatinine, urea nitrogen, uric acid, calcium, protein electrophoresis, and normal immunoglobulin level, as assessed by serum radial immunodiffusion, immunoelectrophoresis or immunofixation), 24 h urine examination (for Bence Jones proteinuria, calciuria, hydroxyprolinuria), BM biopsy and aspiration (with myelogram, for the BMPC %), complete radiological bone survey and special evaluations (such as plasma viscosity, serum alkaline phosphatase isoenzymes, serum P2-microglobulin and thymidine kinase levels, bone marrow plasma cell labelling index, DNA flow cytometry and standard cytogenetics of bone and/or peripheral blood cells) (Riccardi et al, 1991).…”
