BackgroundHigh dose Cyclophosphamide (Cy) and Vinorelbine Cyclophosphamide (Vino-Cy) are stem cell (SC) mobilisation options for patients with multiple myeloma (MM). We present a comparison of mobilisation outcomes using these regimens.Patients and MethodsVino-Cy patients received Vinorelbine 25mg/m2 on day 1, cyclophosphamide 1500mg/m2 on day 2, and pegylated GCSF on day 4 or GCSF 10mcg/kg/day from day 4 onwards. Cy patients were given cyclophosphamide 4000mg/m2 on day 1 and GCSF10mcg/kg/day from day 5 onwards. The target CD34+SC collection was 5 x 106per kg/BW.Results149 patients were included. SC collection was lower in the Vino-Cy group (8.20 x 10 6 /Kg BW) compared to the Cy group (11.43 x 10 6/Kg BW), with adjusted geometric mean ratio of 0.59 (95% CI 0.41 to 0.86, p = 0.006). Time taken to achieve an adequate PB SC count was shorter for Vino-Cy (9 ± 1 day compared to 12 ± 2 days for Cy, adjusted absolute mean difference -3.95, 95% CI -4.85 to -3.06, P < .001). Mobilisation related toxicities (in particular, neutropaenic fever) were greater for Cy.ConclusionVino-Cy is a potential alternative to Cy given the need for effective mobilisation protocols with acceptable toxicity.
