Supplementary Material for: Treatment of Non-Transplant Patients with Multiple Myeloma: Routine Treatment by Office-Based Haematologists in Germany - Data from the Prospective Tumour Registry Lymphatic Neoplasms (TLN)

<b><i>Summary</i></b>Background<b><i>: </i></b>Various treatment options exist for patients with multiple myeloma (MM). Clinical registries provide insight into routine treatment and identify changes in treatment over time. <b><i>Patients and Methods: </i></b>The Tumour Registry Lymphatic Neoplasms (TLN) prospectively collects data on the treatment of patients with lymphoid B cell neoplasms as administered by office-based haematologists in Germany. Data on patient and tumour characteristics, comorbidities, systemic treatments and outcome parameters are recorded. <b><i>Results: </i></b>371 non-transplant patients with MM were recruited between 2009 and 2011. At the start of first-line (second-line) treatment, the median age was 73 (75) years; 67% (74%) of the patients had stage III MM (classification of Durie and Salmon) and 19% (28%) had renal insufficiency. In the first line, 40% of the patients received bortezomib + melphalan + prednisone (VMP), 25% received bortezomib ± dexamethasone (V±D) and 8% were treated with melphalan + prednisone + thalidomide (MPT). While use of bortezomib-based regimens increased from 67% (2009) to 85% (2011), use of melphalan-based regimens decreased from 68% to 48%. The overall objective response rate of treatment was 82%. In the second line, 34% of the patients received V±D and 16% lenalidomide + dexamethasone (LD). <b><i>Conclusion: </i></b>Bortezomib-based regimens dominate the first- and second-line treatment of MM. Future analyses will investigate outcome data, e.g. effectiveness of bortezomib retherapy compared to other second-line treatments.
