PHILADELPHIA-Encapsulating paclitaxel (Taxol) in liposomes almost eliminates nonhematologic toxicities such as neuropathy and greatly prolongs the drug’s half-life, Joseph Treat, MD, reported at the clinical investigators’ workshop. Dr. Treat is Vice Chairman of the Department of Medical Oncology at Fox Chase Cancer Center and Medical Director of the Temple University Cancer Center in Philadelphia. The workshop was sponsored by the University of Texas M.D. Anderson Cancer Center and by Pharmacia Oncology.

HOUSTON-Hereditary cancer syndromes sometimes provide researchers with an accelerated look at cancer pathogenesis and can suggest novel approaches to cancer prevention, Patrick M. Lynch, JD, MD, told an investigators’ workshop sponsored by the University of Texas M. D. Anderson Cancer Center and Pharmacia Oncology. As an example, Dr. Lynch cited the use of celecoxib (Celebrex), recently approved by the Food and Drug Administration (FDA) as adjunctive therapy to reduce the number of polyps developed by patients with familial adenomatous polyposis (FAP).

HOUSTON-Remember the enthusiastic reports in the popular press that antiangiogenic therapy would provide a quick cancer cure by starving tumors of their blood supply? Lee Ellis, MD, quoted H. L. Mencken in describing the aftermath of those reports: “All complex problems have simple answers that are invariably wrong.”

ARLINGTON, Virginia-Research in complementary and alternative medicine (CAM) is possible and feasible, said Andrew Vickers, DPhil, but the key issues are practical and not conceptual. Those who work in CAM rarely have the research skills, the technicians, or the access to suitable patients that mainstream institutions or researchers have, he pointed out.

WASHINGTON-President Clinton included two cancer specialists on the newly created, 11-member White House Commission on Complementary and Alternative Medicine: George M. Bernier, Jr., MD, hematologist/oncologist, University of Texas Medical Branch in Galveston, and William R. Fair, MD, of Long Boat Key, Fla, former chief of the urology service, Memorial Sloan-Kettering Cancer Center, and emeritus professor of urology, Weill Medical College of Cornell University.

WASHINGTON-The US Public Health Service (PHS) has released “Treating Tobacco Use and Dependence: A Clinical Practice Guideline,” which offers trial-based data on first- and second-line therapies to help smokers quit.

ARLINGTON, Va-Nurses often take an active role in integrating complementary and alternative medicine (CAM) with conventional care in the hospital setting, said a panel of nurses at a session of the Comprehensive Cancer Care 2000 conference.

OAKLAND, California-The National Brain Tumor Foundation (NBTF) has announced its new cancer online resource and toll-free telephone number. Patients and family members who have detailed medical questions regarding brain tumors can contact a neuroscience nurse for a free consultation.

SILVER SPRINGS, Md-Recognizing that caregivers are the backbone of our health care system, developers of the Cancer Survival Toolbox advocacy program have added a new audiotape, “Caring for the Caregiver.” The tape provides cancer caregivers with self-advocacy tools to help them better cope with the disease and their own needs.

NEW ORLEANS-A meta-analysis of two independent phase III randomized multicenter studies “further strengthens the conclusion that the combination of irinotecan (CPT-11, Camptosar)/fluorouracil (5-FU)/leucovorin represents a new reference standard in the first-line treatment of patients with metastatic colorectal cancer,” said Leonard Saltz, MD, associate attending physician, Division of Solid Tumor Oncology, Memorial Sloan-Kettering Cancer Center.

NEW ORLEANS-Antiangiogenesis drugs under development may find their greatest utility in early-stage cancer and in combination with other agents, Michael S. Gordon, MD, said at a symposium sponsored by Agouron Pharmaceuticals (La Jolla, Calif). The symposium, “Novel Mechanisms in the Future of Cancer Treatment,” was held in conjunction with the American Society of Clinical Oncology’s 36th Annual Meeting.

NEW YORK-Regimens based on cisplatin (Platinol), irinotecan (Camptosar), and paclitaxel (Taxol) may provide a better alternative than cisplatin and 5-fluorouracil (5-FU) in treating difficult cases of gastric and esophageal cancers. Developing more effective therapies has considerable public health importance because of the high incidence and mortality rates of these cancers, commented Eileen M. O’Reilly, MD, of Memorial Sloan-Kettering Cancer Center in New York.

ATLANTA-The CaverMap Surgical Aid to help surgeons protect the cavernous nerves during nerve-sparing prostatectomy appears not to be specific enough to be clinically useful at present, Patrick Walsh, MD, said at the 95th Annual Meeting of the American Urological Association (AUA).

HOUSTON-Early results of an ongoing phase II trial of irinotecan in relapsed or refractory non-Hodgkin’s lymphoma (NHL) show response rates of 33% to 45% in some NHL subtypes, reported Andreas H. Sarris, MD, PhD, at the clinical investigators’ workshop. For the most responsive subtypes (indolent lymphomas, relapsed aggressive lymphomas, and possibly refractory aggressive lymphomas), patient accrual will continue, reported Dr. Sarris, Associate Professor in the Department of Lymphoma and Myeloma at the M. D. Anderson Cancer Center in Houston. The workshop was sponsored by M. D. Anderson and Pharmacia Oncology.

In treating cancer, discovering new ways to use or modify old drugs can sometimes be as valuable as the identification of new drugs. This point is elegantly illustrated in Dr. Schilsky’s article about capecitabine (Xeloda), a prodrug that leads to high intratumoral levels of fluorouracil (5-FU).

Commonly used by cancer patients, unproven therapies are treatments that the practitioner claims can alter the disease process although there is no proof to support the claim. The reasons for the popularity of uproven

Safety data from two randomized phase II and one abbreviated phase III placebo-controlled, double-blind clinical studies in adult patients with nonmyeloid malignancies indicate that recombinant human interleukin-11 (rhIL-11, also known as oprelvekin [Neumega]) has an acceptable toxicity profile as therapy for the mitigation of chemotherapy-induced thrombocytopenia.

PHILADELPHIA-“Most people would agree that standard-of-care for frontline treatment of advanced colorectal cancer (CRCA) should now be irinotecan (Camptosar) plus 5-fluorouracil/leucovorin (5-FU/LV),” stated Daniel G. Haller, MD, at an investigators’ workshop sponsored by the University of Texas M. D. Anderson Cancer Center and Pharmacia Oncology. As the basis for this assessment, Dr. Haller of the University of Pennsylvania Cancer Center in Philadelphia, cited presentations made earlier this year.

Review of Recent Regimensn

ROCHESTER, Minn-Standard adjuvant therapy for stage III colorectal cancer (CRCA) should be 6 months of 5-flourouracil (5-FU) plus either high-dose or low-dose leucovorin (LV), but new agents “offer the promise of less toxicity and possibly improved survival,” Henry C. Pitot, MD, reported. A consultant in the Division of Medical Oncology at the Mayo Clinic in Rochester, Minnesota, Dr. Pitot described several of these new regimens at a clinical investigators’ workshop sponsored by the University of Texas M. D. Anderson Cancer Center and Pharmacia Oncology.

Ever since the first phase II study of paclitaxel (Taxol) began, there has been ongoing controversy about the optimal dose and schedule of administration of this drug. The initial reports of marked antitumor activity against metastatic breast cancer were obtained using 250 mg/m² administered by 24-hour continuous IV infusion. This schedule was originally developed in an attempt to reduce the incidence and severity of anaphylactic reactions. Subsequent to the determination that this dose and schedule was effective and safe, there were multiple attempts to develop more convenient schedules, and dose/schedules associated with an improved side-effect profile.
