Randomized Controlled Trial Comparative Study Clinical TrialPrognostic impact of blood transfusions on disease-free survival in colorectal carcinoma.
Blood transfusions have been indicated as having an adverse effect on the prognosis of patients treated surgically for cancer. We carried out a randomized trial to investigate whether a predeposit autologous blood transfusion program improved prognosis in patients with colorectal cancer as compared to the current practice of allogeneic transfusion. ⋯ We found that the risk of recurrence was significantly increased for patients transfused with allogeneic, or with autologous, or with both types of blood, compared with those patients who did not require transfusions; relative recurrence rates were 2.3 (p = 0.001), 1.8 (p = 0.044) and 2.5 (p = 0.009), respectively; these three rates did not differ significantly from each other. We conclude that it is not the blood transfusions themselves, but the circumstances that necessitate the transfusions that are the real determinants of prognosis.

Randomized Controlled Trial Clinical TrialTranexamic acid in gastric and duodenal bleeding.
In this prospective, randomized, double-blind study the effect of the antifibrinolytic drug tranexamic acid was compared with that of placebo in 154 patients bleeding from verified benign lesions in the stomach and/or duodenum. Three out of 72 patients receiving tranexamic acid underwent emergency surgery, in contrast to 15 out of 82 in the placebo group (p = 0.010). ⋯ Side effects were seen in six patients, of which an uncomplicated deep venous thrombosis was the most severe. It was concluded that tranexamic acid reduces the blood transfusion requirement and the need for emergency surgery in patients bleeding from a benign gastric or duodenal lesion.
