This, in turn, has produced the negative phenomenon of blaming the victim.
Clinical Oncology, Second Edition
November 1st 2000A comprehensive textbook on clinical oncology should have broad appeal to readers from various disciplines, including educators, clinicians, and scientists working with cancer patients. Students of the medical disciplines must also have a reference textbook to guide them in their educational exploration, whether they are in the field of medicine itself or in complementary areas. We look to comprehensive textbooks not only to provide us with the latest updates in different disease entities, but also to guide us by choosing the most relevant areas of study and investigation. The editors who compiled this textbook have met these challenges, while maintaining a readability that is suitable for various levels of expertise and comprehension

PG-SGA, Latest Advance in Assessing Nutritional Status
November 1st 2000PHILADELPHIA-Over the last 20 years, nutritional assessments in oncology have evolved from just assessing a patient’s nutritional status to using the information to improve outcome. The latest assessment tool is the scored Patient Generated Subjective Global Assessment (PG-SGA) developed by Faith Ottery, MD, PhD, president of the Society for Nutritional Oncology Adjuvant Therapy.
Low-Fat Diet Reduces Areas of Mammographic Density
November 1st 2000WASHINGTON-Density variations in breast images may be due to a number of different variables, such as age and body weight, Norman F. Boyd, MD, DSc, said at the 10th Annual Conference of the American Institute for Cancer Research (AICR).

NOMOS Corporation’s Peregrine Radiation Dose Calculation System Approved for Marketing
November 1st 2000SEWICKLEY, Pennsylvania-The FDA has granted NOMOS Corporation clearance to market the Peregrine Monte-Carlo-based radiation dose calculation system, licensed from the Lawrence Livermore National Laboratory where it was developed. Peregrine is a computer-based system for quick calculation, in three dimensions, of radiation doses for use with complex intensity-modulated radiotherapy treatment plans. Monte Carlo is a mathematical technique that simulates the trillions of radiation particles that enter the body during treatment. It selects a random sample of these particles and tracks them through a computer model of the radiation-delivery device and the patient’s CT scans to create a detailed map of the dose distribution (see image). NOMOS will initially incorporate Peregrine into its CORVUS inverse treatment planning system, and will then develop a stand-alone version to work with other treatment planning systems.
European Study Shows No Benefit for Fiber Supplement in Preventing Polyps
November 1st 2000DIJON, France-In patients with a history of colorectal adenomas, use of a soluble fiber supplement (ispaghula husk) appears to have an adverse effect on recurrence, said Jean Faivre, MD, of the European Cancer Prevention Organi-sation (ECP) Study Group. The study also showed that calcium supplementation produced a modest but not significant reduction in the risk of adenoma recurrence.
