Background:
High 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 Methods:
Vino-Cy patients received Vinorelbine 25 mg/m2 on day 1, cyclophosphamide 1500 mg/m2 on day 2, and pegylated GCSF on day 4 or GCSF 10 mcg/kg/day from day 4 onwards. Cy patients were given cyclophosphamide 4000 mg/m2 on day 1 and GCSF10 mcg/kg/day from day 5 onwards. The target CD34 + SC collection was 5 × 106 per kg/BW.
Results:
149 patients were included. SC collection was lower in the Vino-Cy group (8.20 × 106/Kg BW) compared to the Cy group (11.43 × 106/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.
Conclusion:
Vino-Cy is a potential alternative to Cy given the need for effective mobilisation protocols with acceptable toxicity.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
