Abstract:
Objective: To explore the prognostic factors in newly diagnosed multiple myeloma (NDMM) patients with 1q21 amplification/gain treated with bortezomib-based regimens followed by autologous hematopoietic stem cell transplantation (ASCT) . Methods: We retrospectively assayed 35 NDMM patients with 1q21 amplification/gain who received bortezomib-based chemotherapy followed by ASCT and maintenance therapy between January 2008 and August 2015. Results: ①The median age of 35 patients were 49(33-63)years old. Ratio of male to female was 22∶13. Monosomy1q21 amplification/gain was only seen in 3(8.6%) patients, the other 32 patients were with additional cytogenetic abnormalities including 13q14 deletion, t(11,14), t(4,14), t(14,16), 17p deletion and complex karyotype aberrations. ②The complete remission (CR) rate was 57.0% (20/35), the very good partial remission(VGPR) rate was 37.1%(13/35) and the partial remission (PR) rate was 5.7%(2/35) after ASCT. At a median follow-up of 24 (8-85) months, 3-year estimated progression free survival (PFS) and overall survival (OS) rate were (66.5±9.7)% and (69.6±9.9)%, respectively. ③As 13 patients with high-risk cytogenetic abnormalities, the median PFS and OS time was 26 and 28 months. The 3-year estimated PFS and OS was (28.0±15.9)% and (36.5±16.4)%, respectively. Another 22 patients without other high-risk cytogenetic abnormalities, the median PFS and OS time was 54 months and not reached. The 3-year estimated PFS and OS was (71.5±12.7)% and (92.3±7.4)% in this group, respectively. The presence of additional other high-risk cytogenetic abnormalities resulted in significantly shortened PFS (χ(2)=5.404, P=0.020) and OS (χ(2)=7.596, P=0.006) compared with no high-risk cytogenetic patients. Conclusion: NDMM patients with isolated1q21 amplification/gain were rarely and usually had additional other cytogenetic abnormalities. The outcomes in this group treated with bortezomib-based chemotherapy followed by ASCT and maintenance therapy were satisfied, additional other high-risk cytogenetic abnormalities made PFS and OS further shortened.
