title: Prognostic value of the Banff classification.
abstract: We evaluated whether classification of renal allograft biopsies according to the Banff schema is a predictive parameter for graft survival. All patients who received renal transplants between 1980 and 1994 at the University of Erlangen-Nuremberg (n = 1141) were included. Patients who had undergone a renal biopsy (n = 306) were divided into groups according to the Banff classification. We observed a correlation (P < 0.05) between biopsy findings and the following patient characteristics: donor/recipient age, donor/recipient gender, panel reactive antibodies, maintenance immunosuppression, and primary renal disease. Compared to patients who did not undergo renal biopsy (55.9%), 5-year graft survival was reduced in patients with moderate acute rejection defined by tubulitis (20.6%, P = 0.03) or arteritis (0%; P < 0.0001) and in patients with severe acute rejection (24.4%, P < 0.0001).
  
  
  CONCLUSIONS
  (1). The Banff classification is a predictive parameter for renal allograft survival. (2). Certain characteristics predispose patients to certain biopsy findings.
