Abstract

Although recent investigations have identified that lymphangiogenesis is associated with regional lymph node metastasis and tumor prognosis in non-small cell lung cancer (NSCLC), peritumoral lymphatic microvessel density (LMVD) and its prognostic significance in lung adenocarcinoma remain unknown. In the present study, we assessed peritumoral LMVD in lung adenocarcinoma and investigated its correlation with patient prognosis. Using immunohistochemistry (SP method), the D2-40-positive peritumoral LMVD count in lung adenocarcinoma was found to be 11.56±10.73, which was higher than intratumoral LMVD (P<0.001), and was found to be associated with lymphatic metastasis (P=0.003) and pTNM staging (P=0.046). Furthermore, a significant difference in the patient overall survival time was demonstrated between tumors with a high peritumoral LMVD and those with a low peritumoral LMVD (P=0.005). Finally, using multivariate analysis, it was determined that peritumoral LMVD, lymphatic metastasis and pTNM staging were independent prognostic factors. In conclusion, the results suggest that D2-40-positive peritumoral LMVD may predict the prognosis of lung adenocarcinoma.
