Abstract:
Objective To study lymph node micrometastasis in N0 colorectal cancer patients and its clinical significance. Methods In this study, 548 lymph nodes obtained from 62 cases of No colorectal cancer undergoing curative operation were examined by fluorescent quantity polymerase chain reaction assay for the expression of cytokeratin 20 (CK20) mRNA. Results Micrometastasis was detected in 55 lymph nodes (10.0% ) of 24 cases (39%). According to lymph node anatomical locations, micrometastasis was identified in 15. 8%, 5.0% and 3.3% lymph nodes in group Ⅰ ,Ⅱ and Ⅲ (grouped by the distance from the tumor), respectively. Micrometastasis was correlated with invasion depth of primary tumor, but was notrelated to gender, age, tumor size, tumor site and differentiation. Conclusions The expression of CK20mRNA in lymph nodes in patients with No coloreetal cancer could be used to improve the accuracy of clinical staging, and provide information for rational adjuvant therapy.
