A population-based cohort study of recipients of organs from donors with a recognized history or active cancer has been conducted by linking the Italian National Registry of Transplanted Patients and the National Registry of Donors with Neoplasia Risk. Between 2002 and 2004, 8,198 solid organ transplants have been performed in Italy, 108 of them with organs from 59 cadaveric donors with various risk of neoplasia. There were two reported cases of nonmelanoma skin cancer during the follow up of the transplanted patients, which lasted 27.6+/-11.3 months (234 patient-years). In our study, recipients of organs from donors with various degree of neoplasia risk are exposed to a low risk of cancer transmission.

Background: Only half of the patients waiting for a heart transplant undergo surgery, whereas several patients continue to die while on the waiting list. Donor organ availability still represents a major problem with respect to reducing the length of the cardiac transplant waiting list. One option to improve donor availability is the use of so called "marginal donors." The aims of the present study are to analyze the short-mid term survival of cardiac transplanted patients in Italy, and investigate the effect of donor age on prognosis., Methods: A prospective cohort study including all adult patients who underwent heart transplantations in Italy was used to analyze the main factors contributing to organ survival., Results: From 1995-2002, 2,504 adult subjects underwent a cardiac transplant, and were followed up for a period of 540.9 days. Overall, 1-year graft survival was 83.1%. Organs from donors older than 55 years had a lower survival than organs from younger donors. By multivariate analysis, both donor's and recipient's age seem to be important determinants of graft survival. A more sophisticated analysis shows that the trend of the risk of graft failure according to donor's age is not linear, with a peak at age 47.3 years, and differs according to sex., Conclusions: Results from the present analysis suggest that the association between heart transplant survival and donor's age is not a linear one, but follows a complex mathematical model, with influences of sex, at least in our sample.
