The aim of this study is to evaluate the incidence of malignant tumors in cadaver donors and the possibility of neoplastic disease transmission to the recipients in the Organizzazione Centro Sud Trapianti (OCST) area. Among 1744 potential donors identified from 2003 to 2005, 125 (7.1%) showed an elevated malignant neoplastic risk. In 2003 a malignant tumor was diagnosed in 60 donors of mean age 59.6 +/- 19.9 years (median 62.5, M:36 F:24); in 2004, 33 donors of mean age, 61.4 +/- 15.9 years (median 63, M:19 F:14); in 2005, 32 donors of mean age of 62.8 +/- 15.5 years (median 65.5, M:20 F:12). Prostatic cancer was the most common tumor (23.2%). In 101 of 125 cases (80.8%) the tumor was diagnosed before organ retrieval, in 23 (18.4%) cases, during the donor operation but before the transplant, and in one case (0.8%) after transplantation. Each tumor was evaluated according to the histologic types and grades. From 12 of those donors with neoplasia, 24 organs were retrieved (10 livers, 11 kidneys, 3 hearts) transplanted in 23 recipients (one liver-kidney combined transplant). Three recipients died during the perisurgical period due to causes unrelated to the tumor and therefore were not considered in the follow-up evaluation. Among the remaining nine recipients who had a mean follow-up of 38.83 months (range 9-42), no donor-transmitted disease has become apparent by imaging control. A careful donor evaluation including histologic grading and strict application of Centro Nazionale Trapianti guidelines allowed us to use donors with malignant tumors in selected cases with an apparently reduced risk of transmitted neoplastic disease.
