Tissue inhibitor of metalloproteinase-1 (TIMP-1) inhibits the ability of cancer cells to metastasize, but it can also stimulate cancer development. The aim of this study was to assess the level of TIMP-1 in serum and its expression in patients with colorectal cancer (CRC).

The study group consisted of 43 patients diagnosed with colorectal cancer and 24 healthy volunteers. The level of TIMP-1 was assessed by the ELISA method while the expression of this protein was performed immunohistochemically.

The concentration of TIMP-1 in the sera of colorectal cancer patients was significantly higher than in the healthy control group (p = 0.004). Higher level of TIMP-1 in the sera correlated with female gender (p = 0.045), tumor location in colon (p = 0.016), poorly differentiated tumor (p = 0.034) and higher platelet count in whole blood (p < 0.004). A positive reaction of the protein in cancer cells was observed in 31 cases and was found to correlate negatively with its reaction in peritumoral stroma (p < 0.001).

According to this study, TIMP-1 protein may play an important role in cancer development. The assessment of this molecule in serum and tissue can be useful at the time of diagnosis and can help us to understand the nature of colorectal pathogenesis.
