Abstract Magnetic resonance imaging (MRI) of the spine has demonstrated to be a useful tool for correct staging of multiple myeloma (MM), as it is more sensitive than plain x-rays in detecting vertebral lesions. Furthermore, different patterns of bone marrow involvement (focal, diffuse or normal) can be depicted, and this could contribute to better define the prognosis in newly diagnosed patients. In the present study we prospectively evaluated the clinical and prognostic role of spinal MRI in 120 newly diagnosed MM patients (68M, 52F, median age = 56yrs) that subsequently received high-dose chemotherapy and autologous stem cell transplantion, either single (n=28) or double (n=92). Pattern of marrow involvement was focal in 72 cases (60%), diffuse in 29 (24%) and negative in 19 (16%). Patients with a diffuse pattern showed a significantly higher bone marrow plasma cell infiltration (p=0.05) and beta2 microglobulin values (p= 0.04) as compared to patients with a focal pattern; stage III disease according to ISS was observed in 29%, 8% and 1% of patients with a diffuse, focal or negative pattern, respectively. Response rate to treatment program was similar in the three groups of patients, with a stringently defined CR obtained in 34% of patients with a focal pattern, 29% in those with a diffuse pattern and 35% in patients with a negative MRI. Median progression-free survival showed a trend in favor of patients with a negative MRI (54 months) as compared to those with a focal or diffuse pattern (42 and 38 months, respectively). A focal pattern of bone marrow involvement was associated with a significantly higher probability of experiencing an overt vertebral lesion (73% vs 48% in patients with diffuse pattern, p=0.03), including either a compression fracture or a vertebral mass. Consistently with this finding, also extra-spinal bone lesions were more common in patients with a focal pattern (66%) as compared to patients with a diffuse or negative pattern (42% and 6% respectively) (p=0.05). Serum crosslaps were significantly increased in patients with a focal pattern (7032 pmol/L±635SE vs 5431pmol/L±812SE in those with a diffuse pattern, p=0.04). According to our data, a diffuse pattern of bone marrow involvement could be predictive of a more aggressive disease, even though these data needs to be confirmed in a larger series of patients. A focal pattern of bone marrow involvement at diagnosis could help to identify MM patients more prone to develop skeletal complications, so that a careful monitoring and bisphosphonate therapy should be recommended.

Abstract INTRODUCTION: MRI has a high sensitivity in determining changes in bone marrow induced by metastatic disease or primary neoplasms of the bone marrow. Whole-Body Magnetic Resonance Imaging (WB-MRI) is a novel imaging technique that displays nearly the complete skeletal system in one exam. We investigated the differences between conventional skeletal survey and WB-MRI and their impact on staging of patients with newly diagnosed plasma cell disease. METHOD AND MATERIALS: In 41 consecutive patients with newly diagnosed MGUS (n=5), Multiple Myeloma (n=34) or AL-Amyloidosis (n=2) conventional radiographs and WB-MRI (coronar T1 tse and T2 tirm sequences and sagittal T2 star sequences, 1,5 T MRI with parallel imaging, Siemens Avanto®) were performed. Radiographs and scans were evaluated for diffuse and focal bone marrow involvement in consent by two experienced radiologists blinded for patient name and study time. Staging was performed including clinical data according to the Salmon/Durie classification system and the Durie/Salmon PLUS classification system with inclusion of WB-MRI. RESULTS: In 24 (59%) patients there were no lesions in conventional radiography or MRI. In 17 (41 %) patients results of MRI and conventional radiography were discrepant. 4 (10%) patients had lesions only in MRI, 3 (7%) only in conventional radiography and 10 (24%) in both techniques but in different localization. In 16 (38%) patients with radiological signs of osteopenia there was no diffuse infiltration in MRI or vice versa. We systematically analysed the consequences of WB-MRI on staging of patients based on the newly proposed staging system Durie/Salmon PLUS. Replacing conventional radiographs by WB-MRI resulted in reclassification of 12 patients. 3 patients were reclassified from MGUS or stage I into stage II or III. 9 patients were downstaged from stage III or II into stage I or MGUS. CONCLUSION: WB-MRI is a valuable technique for the initial work-up of patients with Multiple Myeloma. In comparison with conventional skeletal survey there are often differing results with impact on clinical staging and influence on therapy decision. WB-MRI can give additional information in patients with unclear staging situation before onset of therapy. Further evaluation of WB-MRI within prospective studies is warranted in particular with respect to prognostic impact regarding overall prognosis as well as regarding local complications. Until then WB-MRI should be used complementary to conventional radiography or CT-techniques that provide accurate imaging of the bone.
