Book Description
Since our previous symposium in 1995, the pace of research in hormones and cancer has accelerated. Progress in our understanding of hormonal carcinogenic processes has been a direct result of the advances made in cell biology, endocrinology, and carcinogenesis at the molecular level. The newer fields of molecular genetics and cytogenetics already have and are expected to continue to playa major role in furthering our understanding of the cellular and molecular events in hormonal carcinogenesis. It has become increasingly clear that the risk of naturally occurring sex hormones in carcinogenic processes, both in human and in animal models, requires only minute quantities of hormones, at both the serum and tissue levels. Moreover, hormone target tissues for neoplastic transformation, perhaps with the exception of the liver, generally have relatively modest ability to metabolize sex hormones, such as the breast and prostate. Table 1 summarizes the serum, and in most cases, the tissue levels of sex hormones, both endogenously and exogenously ingested, which are associated with increased risk for endocrine-associated cancers such as breast, endometrium, and prostate, as well as the hormone levels of four experimental models that have been shown to elicit high tumor incidences. In contrast to the human, in which the hormone levels are cyclic, however, the latter require continuous hormone exposure at these relatively low levels.

Book Description
It has been over a decade since the First International Symposium on Hormonal Carcinogenesis convened in 199 1. Since then, the field has rapidly expanded with considerable progress in both breast and prostate cancers; while ovarian and endometrial cancer have been hampered, in part, due to the absence of suitable hormone-mediated animal models. While knock-out, transgenic, and cell-culture systems have been extremely useful in identifying specific genelprotein alterations and the ensuing pathways affected, the precise molecular mechanisms whereby sex hormones elicit their oncogenic effects still remain elusive. Moreover, despite the considerable progress made in breast cancer research, the exact role of progestins in the presence or absence of estrogen in breast growth, differentiation, and malignant transformation is lacking. Elucidating the incipient molecular alterations in earlylpre-invasive lesions elicited by these hormones is a growing important focus of this field. The main purpose of these Symposia has been to address vital questions that impact our understanding of the causation, dependency, progression, resistance, and prevention of hormonally-associated cancers. We are indebted to the Scientific Advisory Board members who worked with us reviewing and offering suggestions to finalize the scientific program. We offer special thanks for the guidance and support of Dr. Gerald Mueller. His wisdom played an indispensable role in maintaining the excellence of these Symposia. We also acknowledge the numerous external reviewers that worked diligently to revise and improve the quality of the manuscripts. We are very grateful to Ms. Tandria Price.

Book Description
This monograph, written by well renowned breast cancer expect, Dr. Jose Russo, provides new insight on the pathobiology of breast cancer from the most current advances in the field, translational research, initiation and progression of the disease, the mechanism of invasion and metastasis and the concept of stem cells in treatment and drug resistance. The role of personalized medicine and genomic testing are also explored, which will provide a window to the future progress of cancer care.

Book Description
This book will provide the latest advances in molecular and cellular biology for establishing the foundation of a complete understanding of the mechanisms of breast differentiation leading to cancer prevention. The authors are based on the epidemiological evidence indicating that early first full term pregnancy is a protective factor in human against breast cancer and they have used this paradigm and developed experimental systems in both in vivo and in vitro that have demonstrated mechanistically how the differentiation at the organ and cellular level takes place. This knowledge has provided the blueprint for developing better understanding of the basis of cancer prevention. The transcriptoma analysis of the breast of pre and post-menopausal women has established a genomic signature imprinted in the breast that differs according to the reproductive history of the woman showing that early first full term pregnancy reprogram the organ. This reprogramming takes place at the chromatin level by changing the transcriptional process. The modification of the transcriptional control is due to the expression of non coding RNA sequences and posttranscriptional control driven by the splicesome. The plasticity of the genome of the human breast make possible this reprogramming that is not only induced by the physiological process of pregnancy but by the use of hormones that mimic pregnancy without pregnancy. The author have established the basis of clinical trials for prevention and the discovery that short 15aa peptides of the chorionic gonadotropin hormone can be used in human breast cancer prevention based on preclinical and clinical data.

Book Description
This volume, Biological and Hormonal Therapies of Cancer, which is part of the series Cancer Treatment and Research, presents selected new information concerning biologic and hormonal therapy of cancer. We have attempted to provide the reader with topics of major interest in a timely fashion. There is renewed interest in biologic therapy of cancer. Two chapters review the role of interferon in the hematologic malignancies and in solid tumors. Vaccine therapies have come to the forefront of cancer therapy re cently, and two chapters approach different strategies of vaccine therapies; one reviews the cellular vaccine therapies and another the anti-idiotype ap proach. The hormonal therapy chapters focus on current uses of endocrine therapy in endometrial, breast, and prostate cancer. In addition, hormonal strategies for the prevention of breast cancer and endometrial cancer, including excit ing information relating to phytochemicals, are presented. The effects of tamoxifen on endometrium is a topic of major interest and is discussed in detail. Finally, there is a chapter on estrogen receptor expression and regula tion in human breast cancer. These chapters are all written by experts in the field and contain timely and relevant information of interest to laboratory and clinical scientists and practitioners alike. Biologic and endocrine therapies represent major areas of cancer research interest. The advent of newer biologic therapies, including new antibody targeted treatments, and the use of biologics as tumor modulators to enhance the effects of other treatment regimens is an exploding avenue of research.
