Abstract
- Introduction: The second-line chemotherapy in metastatic colorectal cancer (mCRC) with FOLFIRI-aflibercept demonstrated an increase in survival compared with FOLFIRI in patients previously treated with oxaliplatin-based regimens. Few data are available in patients treated previously with bevacizumab. Our objective is to evaluate the efficacy and safety of FOLFIRI-aflibercept in second-line treatment in patients who have previously received bevacizumab. Patients and methods: This is a observational, retrospective study of patients with mCRC treated with FOLFIRI-aflibercept in 2nd line in eight hospitals in the Valencian Community. Survival, response, and toxicity were analyzed. Results: 122 patients with a median age of 61 years were included. 89% of patients had PS 0–1. The median of PFS (progression free survival) and OS (overall survival) was 5.45 (95% CI 4.74–6.15 months) and 10.15 (95% CI 7.47–12.82 months), respectively. Disease control rate 59.8%. The most common grade 3–4 adverse events were neutropenia (13,1%) and asthenia (9%). The presence of hypertension during treatment with FOLFIRI-aflibercept was associated with a survival benefit. Median of OS was 14.45 (95% CI 11.58–17.32) in patients with hypertension vs 7.78 (95% CI 5.02–10.54) in patients without hypertension (p =.001). Our results suggest that the presence of PS 0, primary tumor surgery, metachronous metastases, and the presence of only 1 metastatic location, are favorable prognostic factors associated with better OS. Conclusions: Our results confirm the value of maintaining angiogenesis inhibition with FOLFIRI-aflibercept in mCRC after progression to a first-line treatment with bevacizumab. The development of hypertension during treatment is a possible predictive marker of response. [ABSTRACT FROM AUTHOR]
