With a long practice of organ transplantation, retransplantation has become a major goal in patients with long-term failure of their first transplant (chronic rejection, exhaustion of the transplant, recurrence of the initial disease, etc. ). In addition, retransplantation can be necessary in the initial period, due to severe acute rejection, a non-functioning organ, or surgical complication. Immunological and non-immunological factors affecting the success of a second transplant are described in this volume, together with alternatives to retransplantation. It is hoped that in the future retransplants will be less frequent, as a result of improved prevention of transplant failure. J. L. Torrroine et a/. (ens. ), Retra isplantation, xvii.

In all varieties of organ transplants, early results have dramatically improved over the past two decades and failures due to acute rejection are becoming rarer. Efficient immunosuppressive regimens have been developed with the objective of very good results at 1, 3 and 5 years. Successful transplants, however, are significantly less frequent at 10 and 20 years, and many patients require retransplantation. Many factors are involved in late graft loss and it is now well recognized that, in addition to chronic rejection, a number of non-immunologic factors play a prominent role. In the case of renal transplantation, a reduced mass loss (transplantation of a single kidney, sometimes from an aged donor, ischemic injury and alteration of some nephrons in the case of early acute rejection) will result in slowly progressing chronic renal failure, even in the absence of any supplementary attack of an immunological nature. The new treatments must be analyzed in the light of their capacity to reduce these late failures. Several preventive measures can also limit both immunologic and non-immunologic factors of late transplant deterioration.

Rejection and Tolerance is the latest subject in the Continuing Education series, organized by Fondation Marcel Merieux and Universite Claude Bernard in Lyon. The annual subject is chosen to reflect the status of the topical issues of the year, as taught by leading international experts. The contribution of transplantation and clinical immunology to advanced medicine is considerable and promising. The annual volumes in this series keep the reader abreast of these developments. "

Over the last few years, transplantation knowledge and techniques, as well as insights into pharmacology, have improved, thus enabling greater access to transplantation for patients. The pool of organs for transplantation is stable, and therefore insufficient to cope with the growing demand. To adjust demand and resources in the most equitable way, organ procurement and allocation have been organized nationally and often across borders. The national and international organ exchange programs were studied and discussed during the Congress on Organ Allocation, from which this book is derived. This book describes the state of the art in the management of waiting lists and the allocation of organs in transplantation. It includes chapters on the possibilities of expanding the pool of available cadaver organs. It also analyzes the results of transplantation of cadaver organs from older donors and marginal, non-heart beating donors. Transplantation policies based on the offering of organs by living donors are also described, as is the impact of delayed graft function on organ allocation.

Malignancies are frequent complications in organ transplantation, mainly as the result of infection with certain viruses and of long-term immunosuppression. The epidemiology confirms that the increased incidence concerns certain cancers, especially HIV-related skin cancers and EBV-related lymphoproliferative malignancies. This book covers all currently available information on this important topic of the relationships between transplantation and malignancies: preexisting cancers, posttransplant cancers, their etiology and pathophysiology, their prevention and treatment. A significant part of the volume is devoted to prophylaxis, early detection and modern forms of therapy in posttransplant lymphomas. As a conclusion of all these new data, the theory of immunosurveillance deserves to be significantly modified.
