Effect of perioperative allogeneic blood transfusion on the prognostic quality of first-stage free flap repair and reconstruction in patients with oral cancer
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 5
Abstract
Objective To study the effect of perioperative allogeneic blood transfusion on patients with oral squamous cell carcinoma (OSCC) after first-stage free flap transplantation. Methods A total of 306 OSCC patients who accepted primary repair and reconstruction using free flap admitted to our affiliation from January 2010 to January 2019 were selected as the research objects and retrospectively analyzed. According to their clinical data, they were divided into three groups: no transfusion group (n=98), 1-2 U transfusion group (n=131) and 3 + U transfusion group (n=77), respectively. The incidence of complications including flap infection, blood circulation disorder and hematoma in the three groups were compared. The five-year survival rate of the three groups was calculated by Kaplan-Meier analysis, and the relative risk of death was analyzed by Cox regression. Results There was no statistically significant difference among the three groups of patients (P>0.05) regarding such baseline data as embracing gender, age, primary location, degree of differentiation, adjuvant radiotherapy and chemotherapy. The complication rate of patients with 3 + U transfusion (25.97%) was significantly higher than that of no transfusion (6.12%) and 1-2 U transfusion (10.86%) (P<0.05); and the five-year survival rate of patients with 3 + U transfusion (51.95%) was significantly lower than that of no transfusion (69.38%) and 1-2 U transfusion (62.60%) (P<0.05). The results of univariate analysis showed that age, adjuvant radiotherapy, degree of tissue differentiation, collateral infiltration, vascular invasion and blood transfusion were all factors influencing the quality of prognosis after repair and reconstruction of first-stage free flap transplantation treating OSCC (P<0.05). The results of multivariate analysis showed that adjuvant chemoradiotherapy was an independent protective factor for the prognosis and survival quality of postoperative OSCC patients (P<0.01); the degree of differentiation, vascular invasion and blood transfusion were independent risk factors for the prognosis and survival quality of postoperative OSCC patients (P<0.05). Conclusion Perioperative allogeneic transfusion in OSCC patients can increase the risk of postoperative complications and directly affect their prognostic quality. It can be regarded as an important risk factor for OSCC patients.
