Abstract

Aim: The aim of this study was to investigate the role of a new inflammatory index (Colon Inflammatory Index [CII]) as a predictor of prognosis and treatment efficacy in patients with metastatic colorectal cancer (mCRC) enrolled in the prospective multicenter randomized ITACa (Italian Trial in Advanced Colorectal Cancer) trial to receive first-line chemotherapy (CT)+ bevacizumab or CT alone. Patients and methods: Between November 14, 2007 and March 6, 2012, 276 patients diagnosed with CRC were available for baseline neutrophil-to-lymphocyte ratio (NLR) and lactate dehydrogenase (LDH). We divided the population into three groups on basis of the CII index. Results: At baseline in all populations, median PFS and OS was predictive of clinical outcome (p<0.0001). Following adjustment for clinical covariates, multivariate analysis confirmed CII index as an independent prognostic factor. The CII index was also predictive when we evaluated the two distinct arms with (p=0.0009) or without bevacizumab (p=0.0001). When we divided right side versus left side for treatment regimen (CT plus bevacizumab versus only bevacizumab), we found a benefit of bevacizumab versus only CT in the right side in patients treated with bevacizumab and not in patients treated with only chemotherapy. Conversely, we found no difference the left side, but we found a difference in the poor group of 4 months in favor to only chemotherapy. Conclusion: Our results indicate that the CII index is a good prognostic marker for mCRC patients in first line treatment with CT with or without bevacizumab.
