SOCRATES in PLATO'S Phaedo (91 a). Preface The first review of malignant lymphomas, other than Hodgkin's disease, in this Handbook series was given by C. STERNBERG in 1926. It comprised seven pages. The magnitude of this second presentation of the same subject reflects the enormous increase in knowledge gathered over the past 50 years. Experimental immunology and lymphocyte research of the past two decades are especially to blame. They forced us to reconsider lymphocytic reactions and neoplasms and to correlate these with new experimental data. In order to make such correlations, it was necessary to apply the tools of experimental immunology to the definition of the cells involved. In this way, it was possible not only to redefine the normal and reactive cells of lymphatic tissue, but also to come to a better understanding of the malignant neoplasms of these cells. In collaboration with E. KAISERLING, N. MOHRI, H.K. MULLER-HERMELINK, and H. STEIN, I have endeavored since 1970 to study and to classify the malignant lymphomas in the light of modern lymphocyte research. Our investigations made use of both special morphologic methods (Giemsa staining in sections, imprints, cytochemistry, and electron microscopy) and immunologic techniques. The major morphologic groundwork for our lymphoma studies was laid by the experimental work of F.J. KEUNING and his school. With the help of the methods we applied, particularly the immunologic techniques, it was possible to confirm some of our earlier, morphologically defined concepts, e.g., the morphologic identity of germinal-center cells and the tumors of these cells. It was also possible, however, to eliminate certain errors made in the past. It was shown, for instance, that most cases of "reticulosarcoma" are actually immuno blastic lymphomas. Furthermore, some new entities were discovered, e.g., lympho plasmacytoid immunocytoma. These and other data encouraged us to make an attempt to draft and pursue a new concept of the malignant lymphomas other than Hodgkin's disease, which are now generally known as "non-Hodgkin's lymphomas". We were honored to have our concept accepted in principle by the other members of the European Lymphoma Club, R. GERARD-MARCHANT, IRIS HAMLIN, F. RILKE, VIII Preface A.G. STANSFELD, and J.A.M. VAN UNNIK. In joint discussions in 1974, the Club worked out a new terminology that was acceptable to all members and will hopefully be acceptable to other pathologists. Since then, it has been called the Kiel Classification. We are also pleased that the clinicians belonging to the Kiel Lymphoma Study Group-foremost A. STACHER and G. BRITTINGER have been able to present preliminary data on the clinical relevance of the new classification. Finally, our optimism was fortified by the findings of R.J. LUKES and R.D. COLLINS, which largely concur with ours in both concept and practical significance. This book is divided into six main sections. First, there is a chapter on normal cytology that supplements and, in some respects, revises the presentation given in Part A of this Handbook (1961). H.K. MULLER-HERMELINK played a major role in the writing of the first chapter. The second chapter is a brief description of the light-microscopic techniques that are used in our laboratories and have proved to be suitable for a precise diagnosis of lymph-node diseases. In the third chapter, a number of basic considerations are presented in relation to malignant lymphomas and their classification. Part Four is the focus of this book. In separate chapters on each type of lymphoma, it describes the histologic, cytologic, and cytochemical features of each one. Furthermore, in conformity with Part A, it provides data on the occurrence, localization, diag nosis, differential diagnosis, and prognosis of the various types of lymphomas. N. MOHRI of Tokyo had a major part in the 'preparation of the histologic and statistical data. In Part Five, E. KAISERLING presents the ultrastructure of the malignant lymphomas. Part Six was written by H. STEIN and describes immunologic techniques and the results of their application to lymphomas. Hodgkin's disease and the malignant neoplasms of reticulum cells have been left out of this book on purpose. Although much is known about Hodgkin's disease, we are still looking for answers to fundamental questions, e.g., the origin of Sternberg-Reed cells. The whole concept of reticulosarcoma and malig nant reticulosis (histiocytosis) was upset by the separation of immunoblastic lymphoma and will have to be reconsidered and studied with new methods. The magnitude of this book may be appalling at first. Nevertheless, it is incomplete in many respects. For instance, the historical review of some of the lymphomas is unjustly confined to the literature written in English, French, and German. Readers who are familiar with other languages are asked to forgive this selection. I recommend the reader who is in a hurry, i.e., the pathologist who is looking for quick information under the pressure of daily routine, to concentrate on the sections Definition and Diagnosis in each chapter of Part Four and on the illustrations. The most important diagnostic criteria are summarized in tabular form. Since the publishers gave us no other choice but to publish this book in English, we were at a loss for a good translation. So we were all the more thankful thatF.D. DALLENBAcH, Deutsches Krebsforschungszentrum, Heidelberg, spontaneously offered to translate the manuscript - truly a great sacrifice for an active scientist. He translated about half of the book. The other half was translated with help of Mrs. M. SOEHRING, our secretary from Boston. A.G. STANSFELD, Department of Pathology, St. Bartholomew's Hospital, Lon- Preface IX don, was then kind enough to read most of the English manuscript from the viewpoint of a lymphoma expert and to make helpful suggestions. The original manuscript of Parts Two, Three, and Four was delivered to the translator in May 1975. Later, we were able to include references that appeared up to July 1, 1976. More recent references could merely be mentioned here and there or added to the footnotes. Parts One and Five were completed in June 1976; again, more recent literature could not be taken into full consider ation. Part Six was not ready until January 1977; the literature cited in that chapter is, understandably, the most up-to-date. It is evident from the text of the chapters written in 1975, however, that the investigations of the past two years have not necessitated any significant changes. We are aware that our concept will not be the last word. The future will have to show how far it fulfills the ultimate criterion of scientific truth, viz.: the ability to forecast events. Nevertheless, we believe that it is time to abandon all the old lymphoma concepts that pathologists have become so fond of, and to embark on a new one that takes account of both the structure and the function of the tumor cells. One should no longer cling to old, scientifically incorrect classifications, even if they have so far been clinically useful-there are no arguments indicating that our new classification is not just as clinically useful. In London in 1973, H. RAPPAPORT quoted an old saying, which is symboli cally inscribed on a bridge: "Alles ist nur ein Vbergang" -everything is merely a transition. Our classification may be seen as such a transition. Its purpose is to help the sufferers from lymphoma without hindering scientific progress. Kiel, February 1978 KARL LENNERT Acknowledgements This book is not the work of just one or five persons-it is the fruit of manifold cooperation, friendship, and criticism. We are therefore indebted to many people for their assistance and guidance. A decisive role in the genesis of this book was played by our clinical partners, particularly those who belong to the Kiel Lymphoma Study Group, which was originally initiated by Professor Dr. A. STACHER, Vienna, and is thriving under the leadership of Professor Dr. G. BRITTINGER, Essen. The groups working in the fields of leukemia and oncology in childhood led by Professor Dr. G. LANDBECK, Hamburg, and Professor Dr. B. KORNHUBER, Frankfurt, made a similar contribu tion to the lymphomas of childhood. Finally, there were surgeons and otolaryngologists at the University of Kie\ (under the leadership of Professor Dr. B. LOHR and Professor Dr. E. MULLER, respectively) and at several other German hospitals who were willing to cooperate with us. All the mentioned clinicians cooperated by sending us fresh tissue, imprints, and tumor tissue specially fixed for electron microscopy. This was the crucial reason why we were able to work out a classifica tion based on morphologic (histologic, cytologic, and ultrastructural), cytochemical, and immuno logic studies. The hours invested by our clinical colleagues were innumerable. The time spent per case often amounted to several hours. This book is a commemorative to such unique, selfless cooperation. Not to be forgotten are the pathologists who normally work with the cooperating clinicians-they willingly agreed to our receiving material from the clinicians and were contented with a copy of our diagnosis. Especially helpful colleagues from the very first were Professor Dr. ALEXANDRA PIRINGER-KuCHINKA, Vienna; Professor Dr. H.-W. ALTMANN, Wiirzburg; Professor Dr. H. BREDT, Mainz; Professor Dr. E. LANGER, Munich; and Professor Dr. W. MULLER, Essen. A second group of colleagues who played a crucial role in the genesis of this book was the so-called European Lymphoma Club, which is made up of Professor Dr. N. CHELLOUL t, Paris; Dr. R. GERARD-MARCHANT, Villejuif; Dr. IRIS M.E. HAMLIN, London; Professor Dr. F. RILKE, Milan; Dr. A.G. STANSFELD, London; Professor Dr. J.A.M. VAN UNNIK, Utrecht; and the author (K.L.). All members of the Club have advocated the jointly created Kiel Classification in their own countries and elsewhere. This scientific and amicable solidarity among lymphoma experts from five different European countries also set an example for cooperation in Europe, i.e., irrespective of national borders. The many suggestions, corrections, and comments made by our Club colleagues are reflected in this book. Their constant support as friends encouraged us to stay on the path and to present this publication. The writer is also indebted to all the people who work at our Institute for the loyalty they showed, either directly or indirectly, during the whole project-directly by being actively involved in the project; indirectly by doing more than their normal share of work to give us time to prepare this book. The indirect helpers are too numerous to mention by name; but they are represented by my head assistants Professor Dr. L.-D. LEDER and Professor Dr. H.-J. STUTTE; Professor Dr. D. HARMS, Head of the Department of Paidopathology; Professor Dr. M.R. PARWARESCH, who introduced us to polyacrylamide-gel electrophoresis; and Dr. E.-W. SCHWARZE, who offered me constant assistance in the work of the Lymph Node Registry. XII Acknowledgments Directly involved in the preparation of this book were: Mrs. M. SOEHRING, who not only helped to translate, but also prepared the English manuscript for publication with a critical eye and good judgment. She also read and corrected all of the proofs with perfection. Miss K. SOHRWEIDE, who typed the German manuscript, and Mrs. S. SOOTER, who typed parts of the English manuscript. Professor Dr. H. UHLIG, who helped us prepare the color photomicrographs with a Zeiss Ultraphot II (photomicroscope). Mrs. H. BLESSMANN, who developed and enlarged the photomicrographs. Mrs. R. KOPKE, who was responsible for enlarging the electron micrographs. Mr. W. VATER, who did all of the graphic work with utmost precision and competence. Mrs. A. ROHDE and Mrs. D. SCHMIDT, who were responsible for the precise preparation of the references. Mrs. SCHMIDT also read and corrected the proofs of the references and footnotes. Mrs. A. LURZ and Mr. W. GLUCK, who prepared the histologic sections of excellent technical quality. Mrs. B. PETERSEN, who assisted with the cytochemical reactions. Mrs. I. HORN, Mrs. K. KONIG, Miss C. MADER, Miss P. MICHEELS, and Mr. E. GROSSKOPF, who assisted with the immunologic investigations. Miss D. AECKERLE, Miss O. BRACKER, Miss F. KHUEN, Miss F. MARTEN, Miss M. NEUBERT, and Miss A. VOGLER, who provided excellent technical assistance in our electron-microscopic laboratory. The preparation of the statistical data was possible only through the effort of the secretarial and technical assistants at our Lymph Node Registry, Mrs. C. BANNER and Mrs. I. KIEKBUSCH. Professor Dr. G. GRIESSER and his assistant Mr. J.D. Voss from the Department of Medical Statistics and Documentation helped us in every way with the computerization and storage of our data. Dr. R. SATODATE, Dr. R. SUGIYAMA, Dr. E.-W. SCHWARZE, Mrs. D. HELBRON, and Mrs. U. MULLER-HERMELINK made contributions to certain chapters and the application of certain special techniques. These are mentioned in the text. The loyal support of those who work at our Institute never faltered, from the time we started to write this book in 1974 until its completion. In addition, however, I received much help, stimula tion, and criticism from colleagues both in and outside Germany. I can name only a few of the many colleagues who gave us substantial support: Professor Dr. Dr. E. UEHLINGER, the Editor of this Handbook, has not only encouraged me with constant sympathy for two decades, but also read this book with a critical eye and made valuable suggestions. Professor W.ST.e. SYMMERS, London, pointed out important matters of style and terminology. Professor Dr. H. ZUR HAUSEN, Erlangen, made a significant contribution to the serology of EBV infection in Burkitt's tumor and Iymphoepithelial carcinoma. Dr. W. HIJMANS, Rijswijk, and Dr. P. LOPES CARDOZO, Leiden, an inimitable pioneer in cytol ogy, were a source of stimulation in fruitful discussions. Dr. F.e. COLLIER, Rutherford, Professor 1. FIORE-DoNATI, Verona, and Dr. RENATE REIF, Zrifin, read various parts of this book. We are grateful for their comments and suggestions. Finally, we wish to thank all skeptics for often questioning us and forcing us to exercise self scrutiny. Many of the studies behind this book, especially those of our immunologic laboratory, would not have been possible without the generous financial support of the Deutsche Forschungsgemein schaft (Sonderforschungsbereich Ill) and the Kind-Philipp-Stiftung. The publishers also contributed all they could to the success of this book. Dr. H. GOTZE accepted and encouraged its publication even before it was written-an expression of unearned trust and his own optimism. Mr. W. BERGSTEDT and Mr. K. TEICHMANN were always willing to help, even when adverse circumstances might have earned their resentment. The color illustrations are worthy of praise, and we thank the Graph. Kunstanstalt Gustav Dreher GmbH, Stuttgart, for their effort. We are much indebted to all the many people who contributed to the success of this book. They all have given more than the actual writers, whose main task was to interpret and verbalize the results of much hard work.
