ABSTRACT
BACKGROUND/AIMS:
Lymph node (LN) metastasis occurs in approximately 10% of patients with submucosally invasive colorectal carcinoma. This study was performed to determine the role of matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) production and microvessel formation on the LN metastasis in submucosally invasive colorectal carcinoma.METHODS:
A total of forty-one subjects with surgically resected submucosally invasive colorectal carcinoma were included in this study. Immunohistochemical staining of MMP-2, MMP-9, TIMP-1, TIMP-2, and urokinase-type plasminogen activator were performed. Angiogenesis was evaluated by counting the number of microvessels in each pathologic specimen as identified by CD34 immunohistochemical staining.RESULTS:
The depth of submucosal invasion was not significantly correlated with the expression of MMP-2, MMP-9, TIMP-1, TIMP-2, or urokinase-type plasminogen activator, but the microvessel count was significantly correlated with the absolute depth of invasion (r=0.312, p<0.05). Upregulation of TIMP-2 was positively correlated with adjacent lymphatic invasion (p<0.05) and increased TIMP-2 expression was correlated with LN metastasis in submucosally invasive colorectal carcinoma (p=0.088).CONCLUSIONS:
These results suggest that the expression of TIMP-2 and the microvessel count may be useful parameters for considering additional surgery after endoscopic treatment of submucosally invasive colorectal carcinoma.
