ABSTRACT
<p><b>OBJECTIVE</b>To determine the clinical results of selected CD34(+) cell autologous transplantation in advanced malignant tumors.</p><p><b>METHODS</b>After pretreatment, fifteen patients aged 12 - 70 (49.5) years with various Stage III or IV malignant tumors were given the sorted CD34(+) cells collected by magnetic-activated cell sorting (Clini MACS, Milteny Biotech, Germany).</p><p><b>RESULTS</b>Peripheral blood progenitor cells (PBPC) from the patients were mobilized by chemotherapy and G-CSF 5 micro g/kg per day. CD34(+) cells gave 2.0 - 5 log depletion after cell sorting, with a median yield of CD34(+) selected cells of 2.4 (0.15 - 12.03) x 10(6)/kg. It gave a median recovery of 64 (52 - 81.4)% and median purity of 98.2 (83.2 - 99.7)%. The median time of neutrophil recovery > 1.0 x 10(9)/L and platelet recovery > 20 x 10(9)/L post-transplantation were 14 (8 - 26) days and 13 (11 - 35) days, respectively. On follow-up of 2 - 33 (11) months, the event-free survival rate was 53.3% (8/15) and the overall survival rate was 66.7% (10/15).</p><p><b>CONCLUSION</b>Transplantation of autologous selected PBPC CD34(+) cells gives prompt and stable engraftment. Selected CD34(+) cell transplantation, being a safe approach, may improve the clinical outcome even in patients with advanced malignant tumors.</p>
