Gastric cancer surgery: clinical outcomes and prognosis are influenced by perioperative blood transfusions
Gastric cancer in patients is often associated with bleeding; when it occurs, especially in the presence of an anemia, a transfusion is necessary to avoid further deterioration of the patient’s clinical state. The aim of this study was to evaluate the relationship between the administration of peri-operative transfusions due to the anemia or the clinical status and the post-operative clinical outcomes. 188 patients diagnosed with of gastric cancer were recruited at Surgery 2 of the Department of General and Specialist Surgery of the Tertiary Care Hospital “A. Cardarelli” of Naples. All patients had a total or a subtotal gastrectomy accompanied by D2 lymphectomy for gastric cancer. The clinical data most frequently associated with blood transfusion is the appearance of a post-operative infection (OR 2.26, 95% CI 0.87–5.79, P = 0.061). If the administration time of transfusion is considered, the clinical outcomes are different: preoperative transfusions showed a higher incidence of infections (OR 2.26, 95% CI 0.87–5.79, P = 0.061) and acute renal failure (OR 2.82, 95% CI 0.70–10.78, P = 0.078); patients who received intra or post-operative transfusions showed a prolonged hospitalization (OR 8.66, 95% CI 1.73–83.00, P = 0.002). The administration of blood products in the perioperative period is correlated in a statistically significant manner to the incidence of infections, acute renal failure and prolonged hospitalization; therefore, transfusions should be avoided unless clinically necessary and in particular intraoperative transfusions should be avoided because the immunomodulation effect linked to surgical stress may be enhanced hence worsening the prognosis.
