Objective To compare the results of mobilization of peripheral stem cells of two different G-CSF dosage schedules in 30 healthy donors. Methods In one group 15 healthy subjects received 5?g/kg filgrastim once daily subcutaneously (SC), while in the other group another 15 individuals received 2.5?g/kg of filgrastim twice daily SC. Peripheral blood stem cells were collected after five days of filgrastim administration, and flow cytometric immunophenotyping was performed for the first harvest. Results The MNC count was 2.93?10 8/kg donor body weight in the 5?g/kg Qd group compared with 4.42?10 8/kg in the 2.5?g/kg bid group (P0.05). Conclusion Administration of filgrastim twice a day at 2.5?g/kg instead of once a day at 5?g/kg is more efficient in mobilizing stem cells without obvious side effect.

Objective To investigate the therapeutic effect and adverse effects of the teniposide-based regimen in patients with primary central nervous system lymphoma (PCNSL). Methods Between March 2011 and July 2013, 16 patients with PCNSL were diagnosed and treated. The clinical characteristics, diagnosis,therapy, results and adverse effects were analyzed. Results Totally 16 patients were enrolled and diagnosed as primary central nervous system diffuse large B-cell lymphoma. All patients received teniposide-based regimen chemotherapy and 9 patients received teniposide plus rituximab. The overall response rate was 87.5 % (14/16), including 10 cases of CR and 4 cases of PR. With a median follow-up of 13.5 months, the progression-free survival (PFS) and overall survival (OS) rates of 2 years were 29.9 % and 66.7 %, respectively. The mainly hematological adverse events were neutropenia, including grade 3 in 4 cases (25 %) and grade 4 just in one case. There was one case of treatment related death. Conclusions The response rate of teniposide-based regimen for PCNSL is promising. The 2 year PFS and OS rates are even higher than results of traditional high-dose methotrexate regimen. The teniposide-based regimen is well tolerated, and the adverse events are acceptable.

Objective:The effect and side effect of the dose-adjusted EPOCH regimen were evaluated perspectively for the pre-liminarily diagnosed angioimmunoblastic T-cell lymphoma. Methods: Nine cases of untreated angioimmunoblastic T-cell lymphoma were diagnosed and enrolled in our department from September 2008 to September 2012. All patients received dose-adjusted EPOCH regimen as first-line chemotherapy. Results: The median age of 9 patients was 54 years. The male-to-female ratio was 2∶1. About 88.9%of all patients were at Ann Arbor stageⅢ/Ⅳ, and 77.8%presented with B symptoms. Anemia was found in 66.7%of 9 patients, and lactate dehydrogenase elevated in 55.6%of patients. After an average of 4.7 cycles of chemotherapy of dose-adjusted EPOCH regi-men, the complete remission rate was 22.2%, and the total response rate was 66.7%. With a median follow-up of 20 months, the 4-year progression-free survival rate was 11.1%, and the overall survival rate was 33.3%. The median survival time was 19 months. The most common adverse events of EPOCH chemotherapy were hematologic toxicity. Grades 3-4 neutropenia and thrombocytopenia were re-ported in 77.8%and 33.3%of patients. Febrile neutropenia was observed in 44.4%of patients. Non-treatment-related mortality was al-so noted. Conclusion: The results of our research showed no clear benefit of treating preliminarily diagnosed angioimmunoblastic T-cell lymphoma with dose-adjusted EPOCH regimen. The main adverse events were hematologic toxicity and could be tolerated.
