Outcome of treatment with Hyper-CVAD regimen in Chinese patients with acute lymphocytic leukemia.
Modern intensive chemotherapy regimens have improved the prognosis for adult patients with acute lymphocytic leukemia (ALL). With these regimens, the complete response (CR) rates are approximately 75% and long-term disease-free survival (DFS) rates are about 20-35%. For patients with high-risk ALL, DFS rates are only 20% or less. Hyper-CVAD regimen is effective in ALL and aggressive non-Hodgkin lymphomas (NHL) with increased CR rates and DFS rates. Between June 2002 and October 2006, 53 consecutive adult patients with newly diagnosed adult ALL were treated with Hyper-CVAD regimen for six to eight cycles. The alternating courses were given every 3-4 weeks or earlier if count recovery occurred. CR rates of 73.6% were achieved in 39 patients, the estimated 2-year survival rate was 82.9% and the estimated 2-year event-free survival (EFS) rate was 87.3%. Side effects were as expected, mostly attributed to myelosuppression. Analysis of prognostic factors suggested that some previously well-established poor prognostic factors such as the degree of leukocytosis and central nervous system (CNS) or testicular involvement were less important with this dose-intensive regimen. However, patients with mediastinal disease had lower CR rates (P<0.05), with the presence of hepatomegaly and t(9;22) abnormalities had poor survival (P<0.05). Compared with other established adult ALL regimens, Hyper-CVAD regimen was associated with significantly better CR rates, overall survival and EFS rates. The long-term follow-up results of Hyper-CVAD were favorable.
