[Podoplanin`s expression in cancer-associated fibroblasts close to tumor budding of invasive edge].

Significant correlations are revealed between tumor budding and depth of tumor invasion (p=0.023)/regional lymph node metastasis (p=0.068), but between POD expression and depth of tumor invasion (p=0.088) only a tendency of correlation is identified. These facts demonstrate critical prognostic value of tumor budding instead POD expression near tumor buds. It was found that intensity of POD expression near tumor buds is statistically analogous to POD expression in the invasive margin (p=0.0016). That means it is not necessary to evaluate POD expression exactly near tumor buds. For the first time stronger POD expression near mucin complexes is reported. That, probably, will allow to use mucin complexes as alternative prognostic factor instead tumor budding, as tumor buds are absent in mucinous adenocarcinoma.
