Similarly, clinical stage and survival showed a relationship which was significantly enhanced by the addition of serum #32-m (Table V). By including the serial measurement of serum /32-m made at 3, 6 and 12 months after diagnosis as well as the initial measurement, a highly significant result was obtained (P <0.001) but only slightly more powerful than that using the initial Table IV Relationship clinical features/laboratory ments at presentation and between measure- survival. p Sex NS Light chain class NS Age < 0.05 Stage* <0.001 Stage* and renal grade* < 0.001 Blood urea < 0.005 Haemoglobin level <0.001 Serum 32-m ?0.001 NS = Not significant. *System of Durie & Salmon (1975). measurement alone.
