Study on Lymph Node Metastasis Correlated to Lymphangiogenesis, Lymphatic Vessel Invasion, and Lymph Node Micrometastasis in Gastric Cancer

Our immunohistochemical analyses using antibodies of D2-40 and CK, including both CK 20 and CK pan, detected a higher incidence of LVIs and LNMs in gastric cancer specimens. This study shows close correlations among lymphangiogenesis related factors, such as LVI, LVD, and LNMM, and patients' prognosis after surgery. Therefore, immunohistochemical evaluations of these factors could be used for the accurate determination of tumor aggressiveness.
