Tissue plasminogen activator (t-PA) antigen and plasminogen activator activity (PA activity) were investigated in 67 cancer patients with a variety of tumors, and compaired with age-matching controls.
Our results show that t-PA antigen was signifficantly decreased in gastric, liver, pancreatic and rectum carcinoma withot metastasis, whereas it was significantly increased in the presence of metastasis. PA activity had no change in all cases.
