NEW ORLEANS-A mutant her-pesvirus has been shown, in vitro and in vivo, to be highly oncolytic against colon carcinoma cells in liver metastases. On-colysis induced by the replication of this virus, combined with cyclophosphamide prodrug activation, appears to hold therapeutic promise in this setting, according to research presented at the Society of Surgical Oncology Cancer Symposium.
CHICAGO-While the main objective in caring for cancer patients has been to prolong life and to focus on short-term and long-term survival, more recent efforts include considerations of health-related quality of life (QOL).[1,2] The World Health Organization defines QOL as “not merely the absence of disease but a state of physical, emotional, and social well being.”[3]
In his excellent review, Dr. Mitsuyasu correctly highlights the three most important ingredients that play a role in the pathogenesis of acquired immunodeficiency syndrome (AIDS)-related Kaposi’s sarcoma (KS)-Kaposi’s sarcoma herpesvirus/human herpesvirus type 8 (KSHV/HHV-8); altered expression and response to cytokines; and stimulation of KS growth by the human immunodeficiency virus (HIV)-1 trans-activating protein, Tat. Recent studies have provided tremendous insight into the process whereby KSHV/HHV-8 creates the inflammatory-angiogenic state that characterizes KS.
Heidelberger and associates[1] synthesized fluorouracil (5-FU) in 1957 after observing that rat hepatomas utilized radiolabeled uracil more avidly than malignant tissues. For the past 40 years, 5-FU has been extensively investigated in various schedules, in combination with biochemical modulators, and for a variety of malignancies.[2]
Dr. Mitsuyasu has been doing clinical research in patients with AIDS-related Kaposi’s sarcoma (KS) since the beginning of the AIDS epidemic, and his review reflects this breadth of experience. It provides a well-rounded and up-to-date assessment of the pathophysiology, evaluation, and treatment of AIDS-related KS that should be a useful guide for practicing physicians.
In his article, Dr. Mitsuyasu concisely reviews a large body of data concerning the etiology, pathogenesis, epidemiology, and treatment of Kaposi’s sarcoma (KS) in the setting of the human immunodeficiency virus (HIV) infection. As he correctly points out, effective highly active antiretroviral therapy (HAART), with its consequent improvements in immune function and decrease in production of viral and cytokine cofactors that promote KS growth, has been partly responsible for the decline of KS incidence in areas with ready access to HIV therapy.
Managing the infectious complications associated with pentostatin (Nipent), used alone or in combination with other agents in patients with low-grade lymphomas, poses a significant problem for clinicians. Since there is limited

The increasing use of systemic and directed liver therapy for patients with hepatic metastases has created a demand for improved accuracy of noninvasive imaging techniques. Computed tomography (CT) and magnetic
The management of hepatic tumors presents a challenging problem. The natural history of primary and metastatic liver lesions portends a poor prognosis. However, surgical resection and newer ablative techniques have had a
NEW YORK-Coping with cancer and the side effects of treatment can be difficult and frustrating for caregivers as well as patients. Frances K. Barg, MEd, Coordinator for Cancer Control Education, University of Pennsylvania School of Nursing, and Mary Pat Lynch, CRNP, MSN, AOCN, graduate faculty, Oncology Advanced Practice Nurse Program, University of Pennsylvania School of Nursing, had some tips for caregivers and answers to their questions at a Cancer Care, Inc. teleconference. They reviewed a number of things caregivers can do to help relieve the most common problems.

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.

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.
