analyzed with special attention to cost effectiveness of this new technology in routine practice of radiation therapy. Published clinical results will be reviewed and in terms of local tumor control, survival and the impact of this new methodology on deduction of normal tissue complications. The objectives of this course are 1) present clinical rationale for 3D conformal radiotherapy; 2) practical utilization of the tools available in 3D CRT systems for Clinicians; 3) review of published clinical results and 4) a brief review of current research and future trends.

303C Hodgkin's Disease - Part h Epidemiology, Pathology, Staging and Management of Early Stage Disease Peter M. Mauch, M.D., Joint Center for Radiation Therapy, Boston, MA Joachim Yaha/om, M.D., Memoria/ S/oan Kettering Cancer Center, New York, NY

Part I of the refresher course on Hodgkin's disease (HD) will: 1. Update the epidemiology, review the theories regarding the etiology and discuss new development in the histologic classification of HD. 2. Review the modifications of staging system and discuss the role of staging laparotomy and the implications of modern imaging information. 3. Review the alternatives for treatment of early- stage HD and results of recent clinical trials. 4. Review principles and techniques of radiation therapy that are relevant to the management of HD.

304C Intravascular Brachytherapy - Part I1: Overview of Animal Data and Brachytherapy Techniques lan R. Crocker, M.D., Emory Clinic, Atlanta, GA Ron Waksman, M.D., Cardiology Research Foundation, Washington, DC

Purpose/Objective: To familiarize the physicians with the experimental models of restenosis and the effect of radiation on these. To discuss controversial areas and items of further investigation. To present currently available systems and systems under development.

305C Physics and Quality Assurance for Brachytherapy-Part Ih Low Dose Rate and Pulsed Dose Rate Howard I. Amols, Ph.D., Columbia University, New York, NY

Purpose: This course is designed as a review of the basic principles of "conventional" low dose rate brachytherapy for the radiation oncology resident and beginning clinical physicist. The historical development of radium and radium substitutes will be discussed, as will classical methods of dose calculations such as Manchester, Quimby, and Paris systems. We also review dosimetry and Quality Assurance practices. Modern trends such as the use of Ir-192, 1-125, and Pd-109 will be discussed. Newer methods of CT and MRI source localization, as well as optimization techniques for permanent implants, particularly US guided prostate implants, will also be discussed.

CONTENT: (1) Basic Principles (2) Early history and Radium (3) Quantities, Units, and dosimetry (4) Traditional systems of dose calculation

(Manchester, Quimby, Paris) (5) Radium substitutes (6) Intracavitary Brachytherapy (7) Interstitial Brachytherapy

306C Meeting the Challenge of Managed Care - Part I1: Designing a Radiation Oncology Department and Setting Up a Clinical Practice Program Marc Halman, Director of Administration, University of Michigan Medical Center, Ann Arbor, MI Chet Szerlag, Administrative Director, University of Chicago, IL

Objective: Identify the business practices necessary to develop a successful radiation oncology department in the current health care environment. Course content will be of interest to new practitioners establishing first time programs or joining existing groups as well as experienced radiation oncologists who are challenged with redesigning programs to be competitive.
