    Abstract:
    Forty-two bone marrow aspirates and biopsies during follow-up examinations from patients with multiple myeloma were reviewed to determine whether the results correlate with the clinical state of the patient at the time of examination. The percentage of plasma cells on biopsy and aspiration, cytological immaturity, patterns of plasma cell infiltration, and the presence or absence of multiple lymphoid nodules and marked fibrosis were cross-tabulated with clinical parameters (hemoglobin levels, osteolytic lesions, and renal function). Hemoglobin levels less than 10 g/dl were more frequent in those with greater than 70% plasma cells on either aspiration or biopsy (P less than 0.05). A nodular histological pattern on biopsy, however, had a higher correlation with hemoglobin levels less than 10 g/dl, and serum creatinine levels greater than 2 mg/dl, than did plasma cell number. The presence of lymphoid nodules correlated with less lytic bone lesions. The degree of fibrosis and plasma cell immaturity did not correlate with any of the clinical parameters. Our findings suggest that reports on bone biopsies should include in addition to the number of plasma cells, the pattern of plasma cell infiltration and the presence or absence of multiple lymphoid nodules.
