MUNICH, Germany-Patients with low-grade lymphoma had a longer disease-free interval when they received radiochemotherapy and stem cell transplant than when they were maintained on interferon-alfa, Wolfgang Hiddemann, MD, PhD, said at the American Society of Hematology annual meeting.
DALLAS-A preclinical study suggests that adding fish oil to the diet of a cancer patient might increase the effectiveness of cancer therapies and improve the patient’s outcome, W. Elaine Hardman, PhD, of the University of Texas Health Science Center at San Antonio, said at the Susan G. Komen Foundation’s 1999 National Grant Conference.
NEW YORK-“Brain metastases are like orphans when it comes to medical specialties. They really do not belong to any particular area,” said Raymond Sawaya, MD, professor and chair of neurosurgery, M.D. Anderson Cancer Center. But evaluation and treatment are improving, he told patients taking part in a teleconference sponsored by the National Brain Tumor Foundation, Cancer Care, Inc., and the Oncology Nursing Society.
WASHINGTON-While acknowledging that tobacco is a major health problem, the Supreme Court has rejected the Clinton Administration’s efforts to create a new federal control effort. It ruled 5 to 4 that “Congress has clearly precluded the Food and Drug Administration (FDA) from asserting jurisdiction to regulate tobacco products.”
ORLANDO-“There are still too many rectums being removed in patients with invasive rectal cancer,” said W. Robert L. Rout, MD, associate professor of surgery, University of Florida, Gainesville. He believes this situation could be improved with the use of preoperative radiotherapy and chemotherapy.
WASHINGTON-Ethnic and racial disparities in health care are too often the result of racism, said Thomas Perez, director of the Office for Civil Rights in the US Department of Health and Human Services. He was one of a number of speakers at the 7th Biennial Symposium on Minorities, the Medically Underserved, and Cancer.
ROCKVILLE, Md-Stung by the failure of several researchers to fully comply with federal gene therapy rules and reporting procedures, the Food and Drug Administration (FDA) and the National Institutes of Health (NIH) have taken a series of steps to tighten the control and monitoring of such trials.

FORT LAUDERDALE, Florida-When managed care companies deny reimbursement for care decided upon by the physician and patient, have they crossed the line from managing medical care to practicing medicine? A panel of physicians, lawyers, patient advocates, and representatives from managed care held forth on this issue at a roundtable held during the Fifth Annual Conference of the National Comprehensive Cancer Network (NCCN).
SAN DIEGO-External magnets are being used to guide a novel, intra-arterially administered chemotherapy delivery vehicle directly to the tumor site (see illustration ). Scott C. Goodwin, MD, chief of vascular and interventional radiology, UCLA Medical Center, reported results of an ongoing phase I/II study of this new regional therapy technique at the annual scientific meeting of the Society of Cardiovascular & Interventional Radiology.
NEW ORLEANS-Pathologic examination of an intraoperative frozen section of the sentinel lymph node (SLN) is less sensitive for breast cancer patients with smaller tumors and/or micrometa-static disease. In a recent study, use of routine frozen section avoided reoperation in only 4% of patients with T1a cancers, but was more useful in other stages, reported Martin R. Weiser, MD, of Memorial Sloan-Kettering Cancer Center.

WASHINGTON-The ongoing revolution in knowledge about the cellular processes that lead to cancer has created a new and potentially far more efficient approach to finding effective therapeutic agents, said Edward A. Sausville, MD, PhD, associate director of the NCI’s Developmental Therapeutics Program.
BETHESDA, Md-Officials of the National Cancer Institute (NCI) and the Centers for Disease Control and Prevention (CDC) have signed a formal agreement to develop what NCI calls “a comprehensive, federally integrated cancer surveillance and cancer control research system.” The two agencies will pool and jointly release their data on cancer incidence and mortality, as well as coordinate various aspects of cancer registry management, including training and methodology development.
To assist in converting patients from one opioid agent to another in their daily practice, many oncologists carry pocket dosage conversion guides based on package inserts approved by the US Food and Drug Administration (FDA). One such guide issued by the manufacturer of transdermal fentanyl (Duragesic), reproduced in Table 3 of the expert consensus article written by Breitbart et al, presents the equivalent of 25 µg/h of transdermal fentanyl as 45 to 134 mg/d of oral morphine. In another guide, distributed by one of the manufacturers of controlled-release morphine, the 25 µg/h strength of transdermal fentanyl is said to be equianalgesic to 15 mg of controlled-release morphine administered every 12 hours (and both are deemed equivalent to 10 mg of controlled-release oxycodone every 12 hours). Faced with such a wide range of conversion factors, it is of little surprise-as Breitbart et al point out-that clinicians often fail to achieve equianalgesia when converting patients from one opioid to another.
The two research groups from Long Island Jewish Medical Center and Yale University have collaborated to write an excellent overview of the biological basis of radio-sensitivity, especially as it applies to radiotherapy. The content of the paper reflects the excellence of these investigators’ contributions to the field of radiobiology. It is particularly refreshing to read an account of radiobiology that does not resort to the mathematical overanalysis that has plagued the field in the past.
Rosen and colleagues have provided a comprehensive review of the biological basis of radiation sensitivity, including recent insights into the DNA damage response. They correctly emphasize that local control of tumors is still a major clinical problem, and that a better understanding of the biological basis for radiation resistance/sensitivity has significant potential to be exploited for therapeutic gain. They also assert that further progress in local tumor control is unlikely to be achieved by technologic improvements in the delivery of such radiation therapies as three-D (3D) conformal radiotherapy, intensity-modulated radiation therapy (IMRT), altered fractionation, or even chemosensitization.
The article by Sarkodee-Adoo and colleagues on the management of infections in patients with acute leukemia provides an authoritative review of approaches to the prevention and treatment of infections in this high-risk population. Indeed, among the different populations of patients with neoplastic diseases, those with acute leukemia, particularly acute myelogenous leukemia (AML), are at very high risk for the development of severe infectious complications.[1,2]
Improvements in outcome following treatment for acute leukemia have derived from various sources: the introduction of new chemotherapeutic agents; the development of effective drug combinations; the use of multistage approaches to induction consolidation, and maintenance therapy to optimize durable control; and advances in supportive care to reduce treatment-related mortality. Certainly, infectious morbidity and mortality have plagued effective antileukemic therapy for many years. As a result, control of infectious complications has been an important area of clinical study. Through the concerted efforts of many clinical investigators, progress has occurred, and, today, infectious mortality is an infrequent complication of antileukemic therapy.
The explosion of new knowledge about radiation sensitivity and radiation biology is such that even the scholarly, relatively extensive review of the subject authored by Drs. Rosen, Fan, Goldberg, and Rockwell covers but a small proportion of this vast, complex topic.
In 1999, metastatic breast cancer claimed the lives of almost 45,000 women. For the vast majority of patients, metastatic breast cancer is an incurable disease with a median survival of only 2 to 3 years after diagnosis. The
