Background:
There are currently no studies examining the relationship between systemic inflammatory response and distant metastasis in colorectal cancer patients.
Aims:
The aim of this study was to evaluate the association of a systemic inflammatory response on distant metastasis by examining clinicopathological factors in patients with colorectal cancer infiltrating the submucosal layer (T1) or the proper muscular layer (T2).
Methods:
Univariate analysis was performed to evaluate the influence of a systemic inflammatory response on distant metastasis in patients with T1 or T2 colorectal cancer using collected clinicopathological data.
Results:
Between 1993 and 2008, 156 patients with pathologically diagnosed T1 or T2 colorectal cancer were enrolled. Univariate analysis using clinicopathological factors and Glasgow Prognostic Score (GPS) (0, 1/2) demonstrated that, as well as lymph node metastasis, administration of oral anti-cancer drug and CEA, CRP (odds ratio, 36.25; 95% CI 4.026-326.4; P = 0.001) and GPS (odds ratio, 24.50; 95% CI 1.715-349.9; P =0.018) were associated with distant metastasis.
Conclusions:
CRP and GPS are associated with distant metastasis of T1 or T2 colorectal cancer. Because of the small number of patients with stage IV disease (n =4), a multi-center retrospective study is needed to confirm these findings.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
