Background: Various treatment options exist for patients with multiple myeloma (MM). Clinical registries provide insight into routine treatment and identify changes in treatment over time.
Patients and methods: 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.
Results: 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).
Conclusion: 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.
