Abstract
-
PURPOSE: To evaluate the correlation between the expression of TIMP-2 (tissue inhibitors of metalloproteinase-2) and negative lymph node involvement of colon and gastric carcinoma.
MATERIALS AND METHODS
We studied 26 cases (13 each) of gastric and colon carcinoma specimens along with dissected lymph nodes by immunohistochemical staining to investigate the correlation of the expression of TIMP-2. Lymph nodes involvement by CT scan was defined by size criteria and the presence of central low density.
RESULTS
Eight cases with positive lymph node involvement by CT scan showed weak expression of TIMP-2. Ten cases with positive lymph node involvement had weak expression of TIMP-2. Among eight cases with strong expression of TIMP-2 7 patients were negative by radiologic exam. Good correlation between strong TIMP-2 expression and negative lymph node involvement by CT scan was found (<0.05).
CONCLUSION
As the expression of TIMP-2 had a good correlation with radiologic involvement of lymph nodes, the study of expression of TIMP-2 in patients with stomach and colon carcinoma might be helpful in planning surgery and predicting the prognosis.
