The plasminogen activation cascade is involved in carcinogenesis, invasion and metastasis. In this study plasminogen activators and their type 1 inhibitor were evaluated in colonic tissue from 19 patients with familial adenomatous polyposis coli, an inherited disorder characterised by the presence of thousands of adenomatous polyps in the colorectum which predispose to colorectal cancer. The conversion of normal-appearing colonic mucosa to neoplastic tissue in these patients was associated with an increase in urokinase-type plasminogen activator and plasminogen activator inhibitor type 1, accompanied by a decreased level of tissue-type plasminogen activator. These observations are essentially similar to those found in solitary adenomas and carcinomas of the colon, and illustrate the uniform involvement of the plasminogen activation system in colorectal carcinogenesis.

A family is reported in which a pair of brothers has developed recurrent venous thromboses, which have been shown in one brother (the proband) to result from a reduced level of tissue plasminogen activator (t-PA) activity. Both brothers have also developed multiple synchronous and metachronous colorectal adenomas. Other pedigree members have developed colon cancers, but not multiple colonic tumours. We have shown that HNPCC and FAP/AAPC are unlikely causes of the family's phenotypes. Previous studies have found low levels of t-PA in sporadic colon tumours. In this family, mutations in the t-PA gene, at a linked locus, or at a locus controlling t-PA activity/release may modify the colon tumour phenotype to cause multiple lesions.
