- Abstract
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.

- Abstract
Objective: To analyze the graft outcome after liver transplantation in Italy in the years 1995 to 2000., Methods: We performed a longitudinal study with follow-up at 3 months, 1 year, 3 years, and 5 years on 1987 liver grafts. The effect of several variables on graft survival was also analyzed., Results: Several variables affect graft survival: Donor and recipient older age, gender mismatching, prolonged cold ischemia time, acute hepatic necrosis, and retransplantation are reported to significantly affect liver graft survival. Donors older than 60 years show a relative risk of 1.59 (95% CI, 1.23-2.05) compared with donors with an age between 19 and 60 years; recipients older than 50 years show a relative risk of 1.29 (95% CI, 1.04-1.60) compared with recipients aged 19 to 50 years. A cold ischemia time of 12 hours or longer doubled the risk of failure (relative risk = 2.01, 95% CI, 1.36-2.96) compared with a cold ischemia time of less than 6 hours., Conclusions: The results show that the overall quality of liver transplantation in Italy is satisfying and comparable to the outcome reported by international registries. Follow-up studies on large numbers of liver transplants are useful to define predictors of outcome, and subsequently modify the criteria for organ allocation.

- Abstract
Purpose: National registry data are often a suitable basis for examination of transplant outcomes. Using data supplied by the Italian National Transplant Registry, established in 1995, we performed the first nationwide analysis of this kind., Methods: A retrospective analysis of 4893 recipients of cadaveric kidneys transplanted in all Italian centers from 1995 through 2000 was done to study 5-year graft survival. The association between some donor and recipient variables and outcomes in renal transplantation was analyzed. Graft survival was 93% at 3 months, 89% at 1 year, 82% at 3 years, and 80% at 5 years after transplantation., Results: A significant association between graft survival and donor age (old vs young, relative risk [RR] = 1.62, 95% CI 1.27-2.06) and recipient age (old vs young, RR = 1.25, 95% CI 1.02-1.53). Graft survival was also associated with cold ischemia time (24-36 hours, RR= 1.39, 95% CI 1.05-1.85 and >36 hours, RR= 1.94, 95% CI 1.32-2.86 vs 0-24 hours) and donor/recipient sex mismatch (female/male vs male/male, RR= 1.50, 95% CI 1.17-1.93)., Conclusion: The quality of kidney transplantation in Italy is satisfactory and is comparable to that in other developed countries. Furthermore, our experience confirms that both donor and recipient factors are major determinants of renal allograft function.

- Abstract
Background: As part of the increased need for transparency and disclosure of information in health care, the Italian Minister of Health has commissioned the Superior Institute of Health to study health outcomes for several procedures, among which is solid organ transplants. We herein report the results of a quality evaluation of solid organ transplants and on the relationship between hospital volume of activity and outcomes, using the data routinely collected by the National Transplant Center during the period 2000 to 2002., Methods: We collected and analyzed all the information on solid organ transplants between 2000 and 2002, along with clinical information before and after transplant. Multivariate survival analysis was performed to adjust the follow-up data for the complexity of the cases. Correlation graphs are presented that assess the association between the number of transplants and the adjusted 1-year survival of both the organ and the patient., Results: One-year survival was 92.4% for kidney, 77.8% for liver, and 83.9% for heart. Patient survival was 97.0%, 84.1%, and 83.9%, respectively. A negative correlation was observed between the number of transplants performed by each center and 1-year survival of the organ., Conclusions: Our study indicated that survival after organ transplants in Italy is good and that hospital quality, indirectly measured through survival, overlaps that observed in other Western countries.

- Abstract
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.

- Abstract
Background: Italian transplantation systems have dramatically improved in the last decade. Kidney transplantations are now strictly monitored and excellent results has been achieved in terms of quality and the ability to reduce waiting times for receiving transplantation., Methods: The Italian organizational retrieval and transplant system is articulated on four levels: local, regional, inter-regional and national. The Italian Transplant Information System (SIT) was set up in 2000 in accordance with Law 91/99. Patient data on the waiting lists and follow-up of transplanted patients are routinely collected., Results: A total of 4406 kidney transplants have been carried out in the 40 Italian kidney transplant centers in 2001-2003. The survival analysis was conducted for the 2000-2002 in 4222 cases. Overall 1-yr survival was 92.4% for the graft and 97% for the patients. After adjusting for variables independently associated with the outcome at multivariate analysis (for example, the case-mix), patient and graft survival at 1 yr was 98.1% and 93.8%, respectively. No remarkable differences in 1-yr graft survival were observed between the 40 Italian kidney transplant centers. At multivariate analysis, variables independently associated with graft failure were donor age, degree of HLA mismatch and recipient case-mix. Analysis of the waiting list showed approximately 6500 patients waiting for kidney transplantation. The mean waiting time was 3.04 yrs, with a mortality rate of 1.18% per year., Conclusions: Kidney transplantation activity in Italy has produced excellent results in terms of quality and number of transplants per year. However, the number of patients on the waiting list and the waiting time call for further action to increase the number of available organs.

- Abstract
This article describes the improvement of organ donation and transplantation in Italy during 1995-1999. In 1999, the mean number of donors per million population reached 13.7 in Italy. In addition, an analysis regarding major characteristics of donors and recipients is presented, focusing particularly on donor characteristics that have changed in the past 5 years. Despite the encouraging results, further efforts are required to reach the European mean, which still remains higher than the Italian national mean. In particular, an increase of organ donation and procurement in regions with a poor activity in this field is crucial. A 1999 law on donation and transplantation should help in solving problems that continue to affect part of the nation, especially preparing the healthcare staff dedicated to organ retrieval to promote organ procurement.

- Abstract
The national programme for paediatric transplants currently implemented at the Istituto Superiore di Sanità is one of the first results of the efforts devoted to the definition of an efficient co-ordination policy of the transplantation activity in Italy. Since 1997 the programme has allowed all transplant centres throughout Italy to share unified waiting lists for kidney, heart, lung and liver, which gives paediatric patients a much better possibility than with local waiting lists. We present the regulations, criteria and operative solutions adopted to make the programme work, and the analysis of the data collected in these three years. The analysis gives statistical information on the composition and evolution of waiting lists and transplants done, which may be useful in the continuous process of revision and improvement of the criteria for recipient selection.

- Abstract
The thesis of this study is that the use of discrete simulations is the most appropriate instrument to support the definition of a kidney allocation procedure. We first furnished a general description of what it means to run a simulation to solve the problems related to the study of the statistical characteristics of any population. In the second part of the paper we mathematically formalized the subject of our study: the statistical properties of waiting lists, allocation algorithm and transplants. The third part reported the results of several simulations we have done with the aim to show the potential of these methods at assessing the most appropriate adjustments for the optimization of any allocation scheme.
