title: Blood transfusion and the risk of recurrence in squamous carcinoma of the vulva.
abstract: OBJECTIVE
  Our purpose was to determine if postoperative transfusion increases the risk of recurrence in patients who have undergone operation for squamous carcinoma of the vulva.
  
  
  METHODS
  Data from 154 patients with squamous carcinoma of the vulva treated at Indiana University Medical Center from 1974 through 1988 were retrospectively analyzed to determine the influence of postoperative transfusion on recurrence risk. Patients were evaluated for International Federation of Gynecology and Obstetrics stage, lesion size, lesion depth, grade, patient age, number of transfusions, and recurrence with chi 2 analysis, Fisher's exact test, and the Student t test where appropriate.
  
  
  RESULTS
  Transfusions were given to 57 patients (37%) with a mean of 2.2 units delivered (range 1 to 5 units). Transfused patients differed significantly from those not transfused in that they had more advanced stage (p = 0.002), more positive nodes (p = 0.03), and higher grade lesions (p = 0.03), and they were older (p = 0.005). Recurrences developed in 25 patients (16.2%). Recurrences were more common in those with positive nodes (10-39, 25.6%) than in those with negative nodes (8/99, 8%), (p = 0.01). Only nodal status was predictive of recurrence in this series. Transfused patients had a 14% (8/57) rate of recurrence, whereas the recurrence risk was 17.5% (17/97) in those not transfused (p = 0.65).
  
  
  CONCLUSIONS
  We have been unable to confirm that postoperative transfusions increase the risk of recurrence in patients with squamous carcinoma of the vulva.
