The influence of peri-operative blood transfusion during radical hysterectomy on the prognosis of uterine cervical cancer

To evaluate the clinical implications of peri-operative transfusion in the surgical treatment of uterine cervical cancer, a detailed analysis of the cumulative survival rate was performed using clinical data from 145 patients with FIGO stage Ib cervical cancer of the squamous cell type acquired between 1982 and 1989 at the Center for Adult Diseases. The cumulative survival rate was statistically analyzed using the Kaplan Meier method. Of the 145 patients with stage Ib cancer, 103 were considered to have undergone complete excision and received no further treatment post-operatively, and 42 were considered to have undergone incomplete excision because of the involvement of lymph nodes or the lymphovascular space. Of the 79 patients in the former group who received peri-operative transfusion, 69 received less than seven units (1400 mL) and 10 received more than eight units (1600 mL). The cumulative 5-year survival rate was 100% in the 24 patients who received no transfusions, 91.7% in those who received less than 1400 mL, and 90.0% in those who received more than 1600 mL. Similarly, of the 42 patients in the incomplete excision group, nine did not receive any peri-operative transfusion, 27 received less than 1400 mt, and six received more than 1600 mt. The 5-year survival rate in these groups was 88.9, 77.8 and 50.0%, respectively. The survival rate of our patients with stage Ib cervical cancer without peri-operative transfusion was significantly higher than that of those with transfusion, regardless of post-operative irradiation therapy status, indicating that perioperative transfusion has an adverse influence on the prognosis in cervical cancer.
