Abstract
PURPOSE: To demonstrate the potential significance of perioperative blood transfusion on the prognosis of gastric cancer. METHODS: Data from 234 patients who were subjected to radical gastrectomy in our hospital were obtained and retrospectively analyzed. Patients' age, gender, preoperative anemia, tumor size, location, invasion depth, lymph node metastasis, TNM stage, presence or absence of blood transfusion and blood transfusion volume were observed and analyzed. RESULTS: The difference of tumor recurrence in patients whose blood transfusion volume was greater than 2U was significant (p<0.001). The tumor recurrence in patients whose blood transfusion was less than 2U was significantly shorter than in those whose transfusion volume was greater than 4U (p=0.03). The survival in the blood transfusion group was significantly lower in comparison with the nonblood transfusion group (p=0.002). The survival of transfusion group in TNM stage III and IV was significantly shorter than that in non-transfusion group (p=0.03). Statistical significance was found in survival between the transfusion group and non-transfusion group when the tumor size was less than 5 cm and greater than 5 cm (p=0.006, p=0.04, respectively). CONCLUSIONS: Perioperative transfusion is one of the factors for predicting the prognosis of postoperative gastric cancer patients, and the larger the perioperative transfusion, the shorter the tumor recurrence, the worse the prognosis. Therefore, it is of great significance reducing the intraoperative blood loss and strict controlling blood transfusion indications.
