TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Hypercoagulability and activation/inhibition of the fibrinolytic system have been observed in abdominal cancer surgery. Because surgery itself and also neoplastic diseases are associated with these situations, a method for separating the origin of these two processes was designed. Eighteen patients with colon cancer who underwent a surgical procedure were studied: Immediately before surgery blood was taken from a peripheral vein. During the surgical procedure, before the exclusion of tumoral tissue from general circulation and at the same time of a second peripheral vein blood sample, a blood sample was taken from the main tumoral draining vein. Platelet-poor plasma samples were aliquoted and stored at -72 degrees C, ready for analytical procedures.', 'A moderate activation of the fibrinolytic system during surgery was observed, expressed by elevation of tissue plasminogen activator (t-PA) (P<.05) and D-dimer (DD) (P<.05) levels, without changes in fibrinogen (FG), plasminogen (PG) or antiplasmin (AP) levels. There were no modifications in antithrombin III (AT-III) and protein C (PC) levels. In the tumoral draining vein samples, there was a high elevation of levels of thrombin-antithrombin III complexes (TAT) (P<.001) and PAI-1 (P<.01), compared with the second sample peripheral vein. There was no difference between peripheral and tumoral vein sample levels of AT-III, PC, FG, DD, PG and AP.'] Do coagulative system activation and fibrinolytic system inhibition activities arise from tumoral draining vein in colon carcinoma?
OUTPUT:

agent
yes
