We conducted a multicenter retrospective study to compare the efficacy and toxicity of various chemomobilization regimens: high-dose (HD) cyclophosphamide, HD etoposide (VP-16), and platinum-based chemotherapies. We reviewed the experiences of 10 institutions with 103 non-Hodgkin lymphoma patients who had previously only been treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)-based chemotherapy. The mobilization yields for each regimen were analyzed. HD VP-16 mobilized a significantly higher median number of CD34+ cells (16.22 × 106 cells/kg) than HD cyclophosphamide (4.44 × 106 cells/kg) or platinum-based chemotherapies (6.08 × 106 cells/kg, P < .001). The rate of successful mobilization (CD34+ cell count ≥5.0 × 106 cells/kg) was also significantly higher for HD VP-16 (86%) than for HD cyclophosphamide (45%) or platinum-based chemotherapies (61%, P = .004). The successful mobilization rate on day 1 of 72% for HD VP-16 was significantly higher than the rates for HD cyclophosphamide (13%) and platinum-based chemotherapies (26%, P < .001). In multivariate analysis, HD VP-16 was a significant predictor of successful mobilization (P = .014; odds ratio, 5.25; 95% confidence interval, 1.40 to 19.63). Neutropenic fever occurred in 67% of patients treated with HD VP-16. The incidence was similar for HD cyclophosphamide (58%, P = .454) but was significantly lower for platinum-based chemotherapies (12%, P < .001). However, fatal (grade ≥ 4) infection and treatment-related mortality were not observed in this study. In conclusion, the mobilization yield was significantly influenced by the chemomobilization regimen, and HD VP-16 was a highly effective mobilization regimen in patients with non-Hodgkin lymphoma.
