Predictive Role Of Peritumoral Cd3+Infiltration And Neutrophil To Lymphocyte Ratio On Overall Survial In Pateints Affected By Colorectal Liver Metastases Treated With Chemotherapy And Surgery.
JOURNAL OF CLINICAL ONCOLOGY(2018)
Abstract
27Background: 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 lymphocyte is well established new evidence on systemic inflammation and cancer such as neutrophil–lymphocyte ratio (NLR) are emerging. The aim of the study is to associate these two markers of inflammation to predict overall survival (OS) in patients affected by CRLM. Methods: From January 2006 to January 2013 128 consecutive patients affected by CRLM treated with chemotherapy and surgery were included in the study. CD3+ peritumoral infiltration was defined as the ratio of intra-tumouralinvasive-margin CD3+ infiltration evaluated with immunohistochemistry on CRLM tumor slides. NLR was calculated as neutrophil absolute count divided by the absolute lymphocyte count on blood sample. ROC curves were used to calculate a cut-off for each bio-markers related to OS . Associating the bio-markers two risk groups ...
