[Effect of hematopoietic stem cell transplantation in malignant hematologic disease of lymphatic system]

The study was aimed to investigate the effect of hematopoietic stem cells transplantation (HSCT) in treatment for hematologic malignancies of lymphatic system. Through observing 8 patients with non-Hodgkin's lymphoma (NHL) and 3 patients with lymphoblastic leukemia, who received auto or allo-HSCT after chemotherapy, the hematopoietic reconstitution, complication and survival time were evaluated. The results showed that 11 patients (7 patients after auto-PBSCT, 4 patients after allo-PBSCT) all achieved hematopoietic reconstitution and complete remission (CR). Within three years following-up, 5 patients with NHL were survival, but one case of NHL died at the 2 months after auto-PBSCT, one patient suicided. From 4 cases received allo-PBSCT, one patient with NHL (NK cell) was died at 79 days later, one patient with chronic lymphoblastic leukemia was surviving, another 2 cases of acute lymphoblastic leukemia were dead at 17 months and 54 days respectively after allo-PBSCT. In conclusion HSCT is an effective treatment for hematologic malignancies of lymphatic system, but the replase would occur in some patients received auto-PBSCT. The others by allo-PBSCT might die of severe complication of transplantation.
