Resumen:	In the RAISE trial, ramucirumab+leucovorin/fluorouracil/irinotecan (FOLFIRI) improved the median overall survival (mOS) of patients with previously treated metastatic colorectal cancer versus patients treated with placebo+FOLFIRI but had a higher incidence of neutropaenia, leading to more chemotherapy dose modifications and discontinuations. Thus, we conducted an exploratory post-hoc analysis of RAISE and a retrospective, observational analysis of electronic medical record (EMR) data to determine and verify the association of neutropaenia, baseline absolute neutrophil count (ANC) and survival. The RAISE analysis used the study safety population (n=1057). IMS Health Oncology Database (IMS EMR) was the source for the real-world data set (n=617). RAISE patients with treatment-emergent neutropaenia had improved mOS compared with those without (ramucirumab arm: 16. 1 vs 10. 7 months, HR=0. 57, p<0. 0001; placebo arm: 12. 7 vs 10. 7 months, HR=0. 76, p=0. 0065). RAISE patients with low ANC versus high baseline ANC also had longer mOS (ramucirumab arm: 15. 2 vs 8. 9 months, HR=0. 49, p<0. 0001; placebo arm: 13. 2 vs 7. 3 months, HR=0. 50, p<0. 0001). The results were similar for IMS EMR low versus high baseline ANC (bevacizumab+FOLFIRI patients: 14. 9 vs 7. 7 months, HR=0. 59, p<0. 0001; FOLFIRI alone: 14. 6 vs 5. 4 months, HR=0. 37, p<0. 0001). Patients in the RAISE trial with low baseline ANC were more likely to develop neutropaenia (OR: ramucirumab arm=2. 62, p<0. 0001; placebo arm=2. 16, p=0. 0003). Neutropaenia during treatment, and subsequent dose modifications or discontinuations, do not compromise treatment efficacy. Baseline ANC is a strong prognostic factor for survival and is associated with treatment-emergent neutropaenia in the analysed population. , Results.
