INTRODUCTION: Autologous stem cell transplantation (ASCT) became standard of care for patients with multiple myeloma (MM) under the age of 65 years. We routinely perform ASCT for newly diagnosed MM since 1996 in our department. PATIENTS AND METHODS: We retrospectively analyzed all 285 transplants in 185 patients done for MM from January 1996 till December 2010. We analyzed overall survival (OS) and progression-free survival (PFS) regarding conditioning, stage, complete or very good partial remission (CR, VGPR) achievement, renal impairment, single vs. double transplant. RESULTS: Estimated 10-years survival of the whole set of patients is 39% (median survival 95 months). Patients with renal impairment show same OS as those without (p = 0.22). Patients show similar overall survival and event free survival regardless of type of transplant. We observed better outcome in terms of overall survival in patients treated with new drugs (p = 0.0014). Reaching CR or VGPR was not translated into better OS (p = 0.30) and EFS (p = 0.10). Also stage of the disease and whether single or double transplant was used did not make any significant difference in the outcome. CONCLUSION: Stem cell transplantation greatly improved outcome of patients with MM. Poor outcome of allogeneic transplantation in our group of patients is related to high transplant related mortality (20% vs. 0%) and unexpected high relapse rate. There is a trend towards better survival, when new drugs are incorporated at any time in the course of the disease. This fact supports hypothesis that use of these drugs with ASCT should translate into better long-term outcome. and J. Radocha, V. Maisnar, A. Zavrelová, M. Cermanová, M. Lánská, M. Kmonícek, L.

Náš projekt byl zaměřen na analýzu možného využití stanovení volných lehkých řetězců (FLC) v séru jako nového markeru k posouzení aktivity monoklonálních gamapatií. Cíle byly formulovány na základě potenciálně nejvhodnějších indikací pro jeho použití v klinické praxi. Spolupracovali jsme s registrem monoklonálních gamapatií a analyzovali celkem 1439 pacientů s monoklonálními gamapatiemi. Potvrdili jsme platnost stratifikačního modelu MGUS Mayo Clinic. Současně s tím jsme identifikovali další potenciálně vhodné znaky, které plánujeme ověřit v rámci dalších analýz a případně je využít při přípravě podrobnějšího stratifikačního modelu. Normalizace poměru FLC v kompletní remisi nebyla spjata se signifikantně delší dobou do progrese, ačkoli byl pozorován trend k jejímu zlepšení., Our project was focused on verifying the usefulness of free light chain (FLC) analysis as the new marker for evaluation of the activity of monoclonal gammopathies. Formulated goals of this project represented the most likely beneficial indications for FLC use in clinical practice. We collaborated with Registry of Monoclonal Gammopathies database of Czech Republic and analyzed 1439 patients with monoclonal gammopathies. We were able to confirm validity of the prognostic model of MGUS stratification originally developed by Mayo Clinic. Moreover several other independent prognostic factors not included in the mentioned model have been identified, which we plan to include in the further analysis and development of more detailed prognostic model. Normalization of FLC ratio was not connected to statistically significant prolongation of complete remission duration, however trend towards it was observed., Radocha J., Klincová M., Maisnar V., Sandecká V., Vávrová J., Špička I., Ščudla V., Gregora E., Machálková K., Tichý M., Malý J., Hájek R., and Literatura 8
