摘要: Background Identifying patients with metastatic colorectal cancer who will have an early disease progression during induction chemotherapy (IC) and identifying may a chemotherapy-free interval (CFI) after IC are two major challenges. Methods A logistic model was used to identify factors associated short duration of the first CFI in 488 enrolled PRODIGE 9 trial. Independent were defined threshold 0.10. Results In multivariate analysis, baseline leukocytes >10 × 109/L (OR = 1.98 [1.02-3.8], p 0.04), stable or increasing CEA at 2 months 3.61 [1.68-7.75], 0.01) independent IC. Male gender 1.725 [0.92-3.325], 0.09) no tumour response evaluation 1.90 [0.96-3.76], 0.07) significantly CFI. The presence BRAF V600E mutation also 4.59 [0.95; 22.3], 0.058). Conclusion High leukocyte count lack decrease level progression, could be favour intensification. gender, CFI, considered for maintenance Clinical trial number NCT00952029.
