Question

Beta-2-microglobulin (B2M) is the most useful predictor of tumor load and disease activity, as well as in predicting the prognosis of multiple myeloma patients. B2M levels correlate with tumor burden, disease progression, and overall survival. Higher B2M levels indicate a poorer prognosis, while lower levels are associated with better outcomes. In contrast, albumin, LDH, BUN, and calcium levels are important markers in multiple myeloma, but they do not provide as much prognostic information as B2M.
