PHILADELPHIA--SmithKline Beecham's Hycamtin (topotecan) has received marketing clearance from the FDA for the treatment of patients with metastatic ovarian cancer after failure of initial or subsequent chemotherapy. It is the first topoisomerase I inhibitor approved for use in the United States.
Endometrial carcinoma was a clinically staged disease until the late 1980s, at which point, staging changed to a surgicopathologically defined system. This change in staging, in turn, altered the clinical management of this
FORT LAUDERDALE, Fla--Although many quality of life measures for cancer have been validated, eg, the FLIC (Functional Living Index-Cancer) and the FACT (Functional Assessment of Cancer Therapy), use of a single instrument facilitates analysis of data obtained at different sites, David F. Cella, PhD, said at the first annual conference of the National Comprehensive Cancer Network (NCCN).
NEW ORLEANS--In combination with cisplatin (Platinol) for treatment of gynecologic malignancies, 3-hour infu-sional paclitaxel (Taxol) might be easier to administer but it produces more peripheral neuropathy than the standard 24-hour infusion, a Cleveland Clinic study shows.
ASCO--Topotecan (Hycamtin), an inhibitor of topoisomerase I, significantly increased time to disease progression--23 weeks vs 14 weeks for paclitaxel (Taxol)--when used as second-line therapy in women with recurrent ovarian cancer, James Carmichael, MD, of the University of Nottingham, said at an ASCO scientific session.
WASHINGTON--University of Pennsylvania researchers have obtained the first "conclusive" evidence linking mutations in the recently cloned BRCA2 breast cancer gene to ovarian cancer, a discovery they say indicates that inheritance plays a significantly greater role in the disease than previously thought.
WASHINGTON--Interim results from an on-going Italian chemopreven-tion trial of a synthetic retinoid show a "borderline significant" protective effect against contralateral breast cancer and, to a lesser degree, against ovarian cancer, but only in premenopausal women.
Almost exactly one decade ago, in an editorial published in the New England Journal of Medicine [1], I noted that "progress is slow but sure" in the development of monoclonal antibodies for clinical use. At that time, only muromonab-CD3 (Orthoclone OKT3) was approved for human use to prevent rejection of kidney transplants. In the ensuing 10 years, only one oncologic monoclonal antibody product, satumomoab pendetide (OncoScint CR/OV, Cytogen, Princeton, New Jersey) [2] has been approved by the FDA. Progress surely has been slow.
Monoclonal antibodies (MoAbs) of murine origin, when labeled with radionuclides that emit gamma rays, target tumors, permitting detection of disease. SatumoMoAb pendetide (Oncoscint CR/OV), a murine MoAb, was
Over the past 5 years, many new cytotoxic agents with activity against metastatic cancer have been discovered, and several are currently undergoing clinical trials. Whether their marked degree of activity represents a real
This review focuses on the clinical utility and potential value of cell cycle analysis and DNA ploidy interpretation in the diagnosis of human tumors, the application of these techniques to cytologic diagnosis, and their capability
Molecular oncology, as it relates to cancer formation, growth, metastasis, and treatment, is a rapidly progressing and exciting field. Its forward movement is so fast that even scientific journals, because of publication delays, are unable to keep readers informed in a timely manner. What, therefore, is the role of a textbook on molecular oncology?
BETHESDA, Md--The FDA's Oncologic Drugs Advisory Committee (ODAC) has unanimously recommended approval of SmithKline Beecham's Hycamtin (topotecan HCl) for the treatment of patients with metastatic ovarian cancer after failure of initial or subsequent chemotherapy.
PALO ALTO, Calif--ALZA Corporation and U.S. Bioscience, Inc. have announced the availability of Ethyol (amifostine), which was FDA approved in December, 1995.
CHICAGO--The Society of Gynecologic Oncologists (SGO) and the Gynecologic Cancer Foundation (GCF) presented awards in four categories at the SGO's 27th annual meeting in New Orleans. The awards are funded by the GCF and were chosen from the more than 115 abstracts presented at the meeting.
LONDON--Women who have persistent elevations in the serum marker CA 125 may be at substantially increased risk for ovarian cancer, a large study of women in the United Kingdom has shown.
NEW ORLEANS--Intraperitoneal (IP) administration of cisplatin (Platinol) plus IV cyclophosphamide produced an improved outcome over IV cisplatin plus IV cyclophosphamide in a pivotal phase III ovarian cancer trial, intergroup study 0051 (SWOG-GOG-ECOG), researchers reported at the Society of Gynecologic Oncologists meeting.
In the past, the mere mention that a patient with persistent or recurrent pelvic cancer might benefit from a palliative pelvic exenteration was met with vigorous opposition. This was due, in part, to the fact that the term "palliative pelvic exenteration" was new and not clearly defined. There was also concern that the mortality, morbidity, and overall cost previously associated with pelvic exenterative procedures were out of keeping with the concept of palliation for cancer. However, much experience with pelvic exenterative surgery has been gained during the past 40 years, and the mortality, morbidity, length of stay, and overall cost of the procedure have decreased significantly. This has made the concept of pelvic exenteration for palliation reconcilable in carefully selected patients in the 1990s.
It is widely accepted that the causation of cancer is the result of environmental exposures (including endogenous hormone exposure) and genetic susceptibility. Ultimately, to prevent breast cancer, we must understand both the environmental and genetic components.
Early trials of an antibody engineered to target two different antigens suggest that the approach may improve the effectiveness of immunotherapy in selected malignancies.
SEATTLE--Genetically modified hematopoietic cells are being used to protect healthy stem cells from toxic drugs in early clinical trials and, in cell lines, to sensitize cancer cells to toxic drugs and to induce leukemia cells to revert to a normal phenotype, Albert Deisseroth, MD, PhD, said at a symposium held in conjunction with the American Society of Hematology meeting. Dr. Deisseroth is associate director for clinical research, Yale University Cancer Center.
Topotecan HCl, an investigational anticancer drug, has demonstrated significant antitumor activity in previously treated small-cell lung cancer (SCLC) patients, according to European Organization for Research and Treatment of Cancer (EORTC) researchers, who presented phase II trial data at the Eighth European Conference on Clinical Oncology, Cancer Research and Cancer Nursing (ECCO-8) in Paris.
SmithKline Beecham plans to launch a study of topotecan HCl, an investigational anticancer drug, in combination with cisplatin (Platinol) for the first-line treatment of ovarian cancer. The development of this protocol was announced at the Eighth European Conference on Clinical Oncology, Cancer Research and Cancer Nursing (ECCO-8) in Paris.
PHILADELPHIA--Women with advanced ovarian cancer had 50% longer survival when they received a first-line regimen combining paclitaxel (Taxol) and cisplatin (Platinol), says William P. McGuire, MD, and his colleagues in the Gynecology Oncology Group (GOG).
The authors offer a comprehensive overview of familial cancer risk counseling, providing both a general definition of this new genetic counseling specialty and specific components of the counseling process. Genetic counseling is, by and large, a referral service, and this is also true of cancer risk counseling. This places great importance on the health-care provider's ability to recognize families who may be at increased risk for an inherited form of cancer and should be referred for cancer risk counseling. It seems reasonable, therefore, to consider the issues relevant to making such a referral, including information on collecting an initial cancer history, strategies for handling a positive history, and the realities of DNA-based testing.
