The prognostic value of P53 in the nodal metastization of gastric cancer.
2017
e14673 Background: Lymph node Metastases play a major role as an independent prognostic factor in gastric cancer. Presence of distal lymph node metastases assumes a pejorative prognostic significance, and represents a problem in terms of therapeutic approach. For this reason it’s of major interest to find predictive markers of distal lymph node chain involvement. The P53 tumor suppressor gene, a product of the TP53 gene works normally as a brake on DNA replication, as suppressor of angiogenesis and triggering of apoptosis. The gene most frequently mutated in gastric cancer is the TP53, that is responsible for the production of P53 mutant protein, which forms inactive complex with the native protein, and manifest by the overexpression of p53 in immunocytochemistry. The overexpression of P53 gene has been considered a bad prognostic factor associated mainly with lymph node metastases. Methods: This study seeks to determine the relation between the expression of P53 and the presence of distal lymph node meta...
