Objective: To evaluate the clinical efficacy and toxicity of priming induction regimen of CAG for newly diagnosed acute myeloid leukemia (AML) in elderly patients., Methods: Seventy-five patients with newly diagnosed AML were divided into 2 groups: 34 were treated with priming induction regimen CAG and the other 41 were treated with 2 classic routine chemotherapy regimens including pirarubicin+cytarabine (TA) and homoharringtonine+cytarabine (HA). All patients had a 14 day interval between the 2 courses of chemotherapy., Results: The complete remission rate after 2 courses of induction therapy in patients with the priming induction regimen CAG and the total efficacy rate was significantly higher than that of the routine chemotherapy patients(67.6% vs. 39%; 82.4% vs. 56.1%). Patients with unfavorable karyotypes had poor chemotherapy efficacy. The 3-year disease-free-survival (DFS) time was longer in patients with AML treated with priming induction regimen CAG than in patients treated with 2 classic routine chemotherapy regimens. Except for the muscular soreness, the hematological and non-hematological side effects in the CAG priming induction group were significantly fewer than those in the routine chemotherapy group., Conclusion: The priming induction regimen of CAG has a significantly higher complete remission rate and an efficacy rate, fewer side effects, milder chemotherapy intensity and is more sensitive to chemotherapeutic drugs than those of the routine chemotherapy. It can shorten the duration of agranulocytosis and decrease infectious complications and increase the sensitivity of leukemia blast cells to chemotherapeutic drugs.

Objective: To explore the relation of the serum level of sIL-2R in relapse patients with acute lymphoblastic leukemia (ALL)., Methods: With ELISA, we determined the levels of sIL-2R of 48 patients with ALL after their first diagnoses, complete remission 1 and relapse. The levels of sIL-2R of 30 patients from complete remission 1 to relapse were monitored., Results: The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the control. The levels of sIL-2R were higher in the relapse group and first diagnosed group than in the complete remission 1 group. However, the difference between the complete remission 1 and the control had no statistical significance. When we determined the levels of sIL-2R dynamically, we found that after complete remission, the levels of sIL-2R decreased, however, before one month of hematological relapse, the levels of sIL-2R increased., Conclusion: Monitor of the level of sIL-2R can predict impending relapse of patients with ALL and is helpful to early diagnosis of relapse.

Objective: To analyze the classification, stage and prognosis of non-Hodgkin's lymphoma (NHL)., Methods: Two hundred eighty two patients with NHL were retrospectively reviewed., Results: The complete remission (CR) rate and 5-year survival rate of B-cell NHL were higher than those of T-cell NHL(P < 0.05). There were significant differences in CR rate and 5-year survival rate among the low-grade, the intermediate-grade and the high-grade NHL(P < 0.05). The CR rate and 5-year survival rate of patients who were treated by the scheme of doxorubicin, cyclophosphamide, vincristine and prednisone (CHOP) were higher than those treated by the scheme of cyclophosphamide, vincristine, prednisone and etoposide (COP + VP16) (P < 0.05)., Conclusion: Rational classification and staging play an important role in the prognosis of NHL. CHOP-based scheme may be regarded as the first choice and the standard scheme of treatment.
