4 Dedication We dedicate this book to the clinicians and scientists who cared for transplant patients and began the work of understanding the problem of PTLD, to the transplant recipients and their families that we care for who motivate these efforts, and to the colleagues we work with to provide care to our patients. Finally, special thanks to our families who had put up with us and supported our efforts in preparing this book and in all other things: Ramnath, Pushpa, Dimple, Shrey and Ria; Jenny, Dave, Erin, Molly, and Allison; Elizabeth, Hannah, and Katie. v

5 Foreword By the mid 1960s, there was evidence that the loss of tumor surveillance in immunosuppressed organ recipients could result in (1) accidental engraftment of donor malignancies, (2) accelerated growth of microscopic metastatic neoplasms of either donor or recipient origin, and (3) an increased incidence of de novo malignancies. Although real, the risks from the first two kinds of complications were promptly minimized by appropriate donor and recipient screening. In contrast, the de novo malignancies, most notably those of lymphoid origin (called posttransplantation lymphoproliferative disorders or PTLDs), have been endemic, or at times epidemic, particularly just after the advent of the T-cell-directed agents, cyclosporine, tacrolimus, and the antilymphoid antibodies. The PTLDs resemble the malignancies found in immune deficiency states, including acquired immunodeficiency syndromes. Originally referred to as reticulum cell sarcomas, they constitute a spectrum of lymphopoietic neoplasms, of which most are B-cell lymphomas that are highly, but not invariably, associated with Epstein Barr virus infection. Because PTLDs are frequently subject to immune surveillance, the pathogenesis and treatment of these lymphoblastic lesions have been of special interest to tumor biologists as well as to clinicians. Heavy immunosuppression, either applied by protocol or in a management response to rejection, usually precedes the appearance of PTLD. Most of these tumors are of host origin in the organ recipients, whereas almost all are of donor origin after bone marrow transplantation. Although PTLDs occur in all kinds of organ recipients, the highest incidence has been after transplantation of nonrenal organs. Reduction or discontinuance of immunosuppression in organ recipients allows recovery of tumor surveillance and may be followed by tumor regression. The most effective treatment is complete discontinuance of immune suppression. However, this drastic step is usually avoided in kidney recipients and is rarely taken in liver, heart, and lung recipients for whom treatment rest and artificial organ support followed by retransplantation are not feasible. Even in such cases, however, stopping immunosuppression as a last resort has been effective in some nonrenal organ recipients without rejection of their allografts. Such examples of donor-specific, but not tumor-specific, immune nonreactivity and other features of PTLD could not be explained until the mechanisms of leukocyte chimerism-dependent alloengraftment and allogeneic tolerance were elucidated with the discovery that organ recipients had leukocyte microchimerism. vii

6 viii Foreword The resulting fresh insight into mechanisms has suggested treatment options for PTLDs beyond stopping immunosuppression or the use of multiple-agent antilymphoma and antiviral therapies. In fact, PTLDs have evolved into a free-standing model in which some mysteries of immunology, virology, and tumor biology have been resolved while others await further discoveries that may be exploited. Meanwhile, many books have been written about transplantation, but none specifically about PTLDs. The three editors of this book are to be commended for their efforts to fill the gap. There is something here for all clinicians, and perhaps for basic scientists who also are looking for new worlds to investigate and conquer. Thomas E.
