Our goal for this second edition of Oncologic Therapies is to again provide a brief introduction to the principles and practice of oncology and to oncologic therapies. The book provides a - scription of the major treatment modalities including surgery, radiation therapy, and systemic therapies including classic chemotherapy and biological therapies as well as a brief ov- view of supportive care and quality of life assessments. This is followed by a discussion of site-specific cancers covering the hematologic malignancies and solid tumors. Each chapter is designed to provide a brief discussion of background infor- tion including epidemiology, risk factors, and staging principles followed by a description of standard therapies according to stage as well as current investigational approaches. While the major pathological and clinical features of each disease are d- cussed, the emphasis of this book is clearly on the state of the art of standard and investigational therapies for each tumor type. As such, this book should be useful to general internists with an interest in oncology as well as housestaff and junior oncologists of all major oncologic modalities seeking a brief and focused patient management resource. References providing more - depth discussion for each field are also provided. We rec- mend that any information pertaining to specific chemotherapy regimens and dosing be confirmed in a primary reference since we cannot exclude the possibility of an occasional typograp- cal er.
