First Studies of Whole-Body Screening CT Mixed
April 1st 2003CHICAGO-According to early experience at one imaging center in Massachusetts, whole-body screening CT is attracting individuals who may benefit from early detection of disease, such as current or former smokers and persons with other risk factors for cancer and heart disease. These researchers found that whole-body screening CT is not, as some have feared, leading to additional unnecessary invasive and expensive testing. However, a California study found that nearly half of persons with an abnormality found on screening required follow-up testing.
Cancer Issues Among IOM's 20 Priorities for Improving Health Care
April 1st 2003Two cancer-related issues-evidence-based cancer screening andpain control in advanced cancer-are among 20 priority areasthat an Institute of Medicine (IOM) committee has urged publicand private organizations to focus on as a way of transforming healthcare in the United States. Goals regarding screening, especially forcolorectal and cervical cancer, the report said, are "to increase thenumber of people who receive screenings and to provide timely followup."Regarding pain control in patients with advanced cancer, thecommittee urged efforts to "emphasize cooperation in protocols acrosscare settings, advance planning for changes in settings, as well asheightened pain, and public education regarding the merits of opioidmedications in this area."

Fulvestrant Is Effective for Patients Failing Other Hormonal Therapy
March 1st 2003BERN, Switzerland-The antiestrogen fulvestrant (Faslodex) is an effective and well-tolerated treatment option for women with heavily pretreated, hormone-sensitive advanced breast cancer, according to an interim analysis from an ongoing study by the Swiss Group for Clinical Cancer Research (SAKK), based in Bern, Switzerland. All of the patients in the study had failed both tamoxifen and an aromatase inhibitor, but 11 of 32 patients (34%) had prolonged clinical benefit on fulvestrant 250 mg every 28 days.
Conventional Factors Do Not Explain Higher Mastectomy Rate in US Compared to UK
March 1st 2003EVANSTON, Indiana-Analysis of traditional factors that correlate with choice of mastectomy or breast-conserving surgery failed to explain the significantly higher mastectomy rates in the United States compared to the United Kingdom seen in the international Arimidex (anastrozole), Tamoxifen, Alone or in Combination (ATAC) trial. ATAC investigator Gershon Y. Locker, MD, noted the striking difference "in the mastectomy rates between the two largest accruing nations in ATAC-the United Kingdom with a 42% mastectomy rate and the United States with a 51% mastectomy rate. This is a 21% increased risk of having a mastectomy if enrolled in the United States compared to the United Kingdom."

Management of Health-Care–Associated Infections in the Oncology Patient
March 1st 2003Each year, 2.4 million patients in the United States develop healthcare–associated infections (HAIs), requiring treatment at an annualcost of approximately $4.5 billion. HAI is the primary cause of deathin approximately 30,000 patients and contributes to the death of 70,000annually. Oncology patients are more susceptible than other patientsto HAIs due to compromised immune systems, surgery (drains),invasive technology (catheters), and environmental factors. This paperwill review each of these risk factors and discuss preventive steps suchas a predictive index, antibiotic therapy, and infection control practices.
