Overexpression of the ITGAV gene is associated with progression and spread of colorectal cancer.

Background/aim: The interaction of neoplastic cells with the extracellular matrix is a critical event for the initiation of cancer invasion and metastasis. We evaluated the relationship between the expression of SPARC, ITGAV, THBS1 and VCAM-1 genes of extracellular matrix in the progression and dissemination of colorectal cancer (CRC).

Patients And Methods: Adult patients (N=114) underwent resection of CRC.

Relationship between the expression of the extracellular matrix genes SPARC, SPP1, FN1, ITGA5 and ITGAV and clinicopathological parameters of tumor progression and colorectal cancer dissemination.

Objective: To evaluate the relationship between the expression of the extracellular matrix (ECM) genes SPARC, SPP1, FN1, ITGA5 and ITGAV and the histopathologic parameters of neoplastic progression and colorectal carcinoma (CRC) dissemination.

Methods: A retrospective study was conducted in 114 patients with stage I-IV CRC who underwent primary tumor resection. Quantitative real-time PCR and immunohistochemistry (IHC) assays were performed in samples obtained from the primary tumors.
