Peri-tumoural CD3+ Inflammation and Neutrophil-to-Lymphocyte Ratio Predict Overall Survival in Patients Affected by Colorectal Liver Metastases Treated with Surgery
Background Systemic and local inflammation plays an important role in many cancers and colorectal liver metastases (CRLM). While the role of local immune response mediated by CD3+ tumour-infiltrating lymphocytes is well-established, new evidence on systemic inflammation and cancer, such as neutrophil-lymphocyte ratio (NLR), is emerging. The aim of this study is to seek an association between the CD3+ lymphocytes and NLR with patients’ prognosis and possibly stratifying it accordingly. Methods From January 2005 to January 2013, 128 consecutive patients affected by CRLM and treated with chemotherapy and surgery were included in the study. Different cutoff levels were calculated with ROC curves for each of the biomarkers, and their relative outcome in terms of overall survival (OS) and recurrence-free survival (RFS) was determined. Associating the two biomarkers, three risk groups were determined: low risk (two protective biomarkers), intermediate risk (one protective biomarker) and high risk (no protective biomarker). Results After a median follow-up of 45 months, median OS and RFS were 44 and 9 months, respectively. For OS, 29 (22.66%), 59 (46.09%) and 40 (31.25%) patients were in the low, intermediate and high-risk groups, respectively. Adjusted Cox regression analysis showed an increased risk of death in the intermediate group (HR 2.67 p = 0.007 95% CI 1.31–5.42) and high-risk group (HR 2.86 p = 0.005 95% CI 1.37–5.99) compared to the low-risk group (reference). Conclusion Systemic and local immune response index allows stratification of patients in different OS and RFS risk groups..
