LOS ANGELES--Bioengineered antibodies against HER2 received major attention at the the 34th Annual Meeting of the American Society of Clinical Oncology, but other approaches to HER2-expressing tumors are waiting in the wings. One uses an antitumor peptide vaccine to induce specific T-cell immunity to HER2. Another uses anti-HER2 immunoliposomes to steer intracellular delivery of antitumor drugs.
NEW YORK--Cancer Care, Inc. has launched a new online resource for ovarian cancer patients and their families and friends. A new section added to Cancer Care’s website (www.cancercare.org) offers a comprehensive overview of ovarian cancer and a resource guide.
Two phase III, multicenter clinical trials are seeking patients to participate in studies evaluating PSC 833, an investigational agent,in combating multidrug resistance in patients with acute myelogenous leukemia. The studies, sponsored by Novartis,
Irinotecan (CPT-11 [Camptosar]) has a broad range of antitumor activity. Extensive preclinical and early clinical work has demonstrated its activity against many tumor types--head and neck, esophagus, stomach, pancreas,
Predisposition testing (ie, genetic testing that provides information about a person’s susceptibility to disease) is now available for several inherited forms of cancer. Individuals who are found to have an altered gene (eg, a
Irinotecan (Camptosar), an active agent in the treatment of fluorouracil-refractory colorectal cancer, has antitumor activity in upper gastrointestinal cancers. Clinical trials from Japan indicate antitumor responses in gastric and
SAN DIEGO--A study of 1,000 patients who received high-dose chemotherapy (HDC) with peripheral blood stem cell (PBSC) support in the community setting showed treatment-related mortality rates similar to those reported at academic centers, said C. Dean Buckner, MD, scientific director of Response Oncology, Inc. and a founder of the Fred Hutchinson Cancer Research Center. He spoke at a symposium sponsored by the University of California, San Diego.
Predisposition testing (ie, genetic testing that provides information about a person’s susceptibility to disease) is now available for several inherited forms of cancer. Individuals who are found to have an altered gene (eg, a
LOS ANGELES--The use of cisplatin (Platinol)/paclitaxel (Taxol) for first-line treatment of advanced ovarian cancer gained additional support from the final survival analysis of a major international study presented at an ASCO scientific session.
GLASGOW--Docetaxel (Taxotere) used in combination with carboplatin (Paraplatin) appears to be an active and well-tolerated first-line treatment for advanced ovarian cancer, producing minimal neurotoxicity. Only 5% of patients experienced neuropathy, said lead investigator Paul Vasey, MD.
In order for the immune system to protect against cancer, it must recognize tumors as "non-self." Markers present on the surface of tumors, known as antigens, allow the immune system to recognize tumors as non-self. However, in order for the
LOS ANGELES--Interim analysis of a major German-Austrian trial comparing cisplatin (Platinol)/paclitaxel (Taxol) with carboplatin (Paraplatin)/paclitaxel as first-line treatment in ovarian cancer found significantly less toxicity with carboplatin/paclitaxel, with no apparent loss of efficacy.
As Drs. Sabbatini and Spriggs point out in their review, the majority of ovarian cancer patients continue to present with advanced-stage disease, and only a minority are cured after primary surgery and chemotherapy. At present, recurrent disease is best viewed as a chronic illness that requires ongoing management. A number of therapeutic options are available, but opportunities for cure remain limited. My comments will focus on post-remission therapy, small-volume residual disease, intraperitoneal therapy, secondary cytoreductive surgery, choice of second-line chemotherapy, and participation in phase II studies.
Approximately, 27,000 new cases of ovarian cancer are reported in the United States each year, and about 15,000 of those result in death. The 5-year survival rate of patients with advanced disease is about 50%. However, when cancer is diagnosed
NEW ORLEANS--After delivery with a cationic liposome complex, the tumor-suppressor gene E1A was expressed by cells in many places in the body, Naoto Ueno, MD, of the M.D. Anderson Cancer Center, reported at the 89th annual meeting of the American Association for Cancer Research (AACR).
Despite the activity of initial chemotherapy in ovarian cancer, the majority of women presenting with advanced disease will ultimately experience disease recurrence and be required to consider second-line, or salvage, chemotherapy options. The well-written, informative article by Sabbatini and Spriggs provides a fairly comprehensive overview of important factors to consider when determining the most appropriate treatment options in this clinical setting.
Patients with epithelial ovarian cancer must receive optimal surgical care and state-of-the-art chemotherapy in the primary treatment setting. The salvage treatment of women with recurrent or persistent ovarian cancer remains a
The distribution of abdominal serous carcinoma in the female ranges from ovarian carcinoma with no tumor involvement of the peritoneum to peritoneal carcinoma with no evidence of carcinoma in the ovary. For the purposes of investigation and patient care, it has been necessary to formulate criteria to distinguish tumors that are most probably primary ovarian carcinomas from those that are most likely primary peritoneal cancers.
Drs. Eltabbakh and Piver present a comprehensive review of the management and prognosis of patients with extraovarian primary peritoneal carcinoma (EOPPC). Increased recognition and more precise definition have led many physicians and scientists to recognize EOPPC as a distinct clinical entity with a unique etiology. However, staging and treatment criteria for EOPPC have been modeled after criteria for papillary serous ovarian cancer, which is clinically and histologically similar. The Gynecologic Oncology Group (GOG) has allowed the inclusion of patients with EOPPC into clinical trials designed for patients with epithelial ovarian cancer.
BUFFALO, NY--It appears possible to break immune tolerance to carcino-embryonic antigen (CEA) utilizing a vaccine that is the internal image of CEA, said Kenneth A. Foon, MD, director of the University of Kentucky Markey Cancer Center, Lexington.
Extraovarian primary peritoneal carcinoma (EOPPC), a relatively newly defined disease that develops only in women, accounts for approximately 10% of cases with a presumed diagnosis of ovarian cancer. Characterized by
NEW ORLEANS--Most women with a family history of breast cancer have a familial predisposition to the disease, rather than true hereditary breast cancer. A comprehensive family history should guide the recommendations regarding testing for a genetic mutation, which, at about $2,400, should not be taken lightly, said speakers at an AMA-sponsored program on genetic medicine and the practicing physician.
Breast cancer, the most common malignancy in women, frequently develops during the premenopausal years. The great majority of these breast cancers can be successfully treated, and the decision to have children remains a real and important consideration. The relationship between breast cancer and a subsequent pregnancy is complex, and decisions regarding one may ultimately affect the course or outcome of the other.
BETHESDA, Md--Bristol-Myers Squibb went 2-for-2 before the FDA’s Oncologic Drugs Advisory Committee (ODAC). The panel recommended that the FDA approve injectable Taxol (pacli-taxel), in combination with cisplatin (Platinol), for both the first-line treatment of ovarian cancer and for the treatment of non-small-cell lung cancer (NSCLC) in patients who are not candidates for potentially curative surgery and/or radiation therapy.
PARIS--The demonstration that adding paclitaxel (Taxol) to platinum boosts survival in advanced ovarian cancer has made this combination the gold standard of chemotherapy for previously untreated patients. [ODAC recently recommended to the FDA that paclitaxel be formally approved for this indication; see page 33.] However, although as many as three-quarters of women will respond to platinum-paclitaxel and one-half will achieve complete clinical remission, most will eventually relapse.
