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 es...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
