نبذة مختصرة : Tensins belong to the group of adhesion proteins that are involved in cell adhesion and migration, actin cytoskeleton maintenance and intercellular communication. TNS1, TNS2 and TNS3 proteins expression was evaluated in 90 patients with gastric cancer by immunohistochemistry method. TNS1 was more frequently present in non-differentiated tumors compared to poorly and moderately differentiated tumors ( p = 0.016). TNS1 was also more often observed in metastatic tumors compared to those without distant metastases ( p = 0.001). TNS2 was more common in moderately differentiated tumors than in poorly or non-differentiated ones ( p = 0.041). TNS2 expression was also more frequently present in tumors with peritumoral inflammation ( p = 0.041) and with concomitant H. pylori infection ( p = 0.023). In contrast, TNS3 protein was more prevalent in moderately than in poorly and non-differentiated tumors ( p = 0.023). No significant relationship was found between tensins’ expression and the overall survival rate of patients. TNS1 protein expression is associated with a poor-prognosis type of GC. Higher expression of TNS2 is accompanied by peritumoral inflammation and H. pylori infection, which favor the development of GC of a better prognosis, similarly to higher TNS3 protein expression.
