Ovarian Cancer

Hospitalized oncology patients are at particular risk for acute venous thromboembolism (VTE); however, more often than not, a standard for VTE prophylaxis does not exist, according to Jerelyn Osoria, RN, OCN, of Memorial Sloan-Kettering Cancer Center. Ms. Osoria reported at the Oncology Nursing Society 31st Annual Congress (abstract 113) that an electronic medical orders system and better nursing documentation have helped improve this situation at her institution's Gynecology (GYN) oncology inpatient nursing unit.

An innovative cancer agent called PHA-739358, which inhibits one of the aurora proteins, has shown indications of potential benefit in 7 of 36 patients (19.4%) with advanced or metastatic solid tumors who participated in a phase I dosing and toxicity study, Dutch researchers reported at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics

I was diagnosed with ovarian cancer seven and a half years ago. The news was overwhelming. The painting depicts how I began; absorbing the shock and then going through the feelings of loss, bewilderment, and fear of the unknown.

Grade 3 and 4 neutropenia as well as febrile neutropenia have been demonstrated to occur in all tumor types and are clearly associated with major morbidity and significant mortality; this is particularly true when myelosuppressive regimens are used with curative intent as is the case in most breast cancer and non-Hodgkin's lymphoma regimens. Myeloid colony-stimulating factors (CSFs) substantially decrease the risk of severe and febrile neutropenia. Although the white cell growth factors might not be cost-effective at lower risks of febrile neutropenia, they clearly benefit other outcomes such as the incidence of severe neutropenia and febrile neutropenia, hospitalization, and mortality. Updated guidelines from the American Society of Clinical Oncology, the National Comprehensive Cancer Network, and the European Organisation for Research and Treatment of Cancer now recommend primary prophylaxis or first-cycle use of white cell growth factors with regimens where the occurrence of febrile neutropenia is approximately 20% (as well as when other risk factors are present). This article briefly describes the rationale for the development of several of the guideline changes as well as highlights some of the ongoing issues related to the use of CSFs.

Clinical studies do not validate the power of manygenomic tests developed to diagnose andguide the treatment of ovarian cancer todecrease the disease’s mortality or improvethe quality of life of patients, accordingto a report released by the Agencyfor Healthcare Research and Quality(AHRQ).

The risk reduction for breast and ovarian cancer associated with salpingo-oophorectomy (SO) in high-risk women varies according to the type of BRCA mutation,

New research shows that the oncolytic reovirus, which kills cancer cells by replication within the cell, may also have the potential to prime the immune system to mount a defense against cancer cells

A new bioengineered protein that targets two apoptosis receptors produced one dramatic tumor regression and stopped tumor growth in several cases of disease stabilization in 60% of the advanced cancer patients treated in a phase I dose-finding trial

Brain, lung, and ovarian cancers have been chosen as the first cancers to be studied in the pilot phase of The Cancer Genome Atlas (TCGA) project

 I read with great interest the paper by Michael Brave and colleagues from the US Food and Drug Administration (FDA). The authors describe the FDA's review supporting this first approval of a chemotherapeutic drug for advanced cervical cancer. This decision was made after a Gynecologic Oncology Group trial (GOG-0179) conducted at 94 American study centers demonstrated a survival benefit in patients with stage IVB, recurrent, or persistent carcinoma of the cervix who received cisplatin plus topotecan (Hycamtin) compared with those who received cisplatin alone.

Topotecan, a camptothecin analog previously approved for the treatment of ovarian cancer and small-cell lung cancer, was granted regular approval by the US Food and Drug Administration (FDA) on June 14, 2006, for use in combination with cisplatin to treat women with stage IVB, recurrent, or persistent carcinoma of the cervix not amenable to curative treatment with surgery and/or radiation therapy. The purpose of this summary is to review the database supporting this approval.

The US Food and Drug Administration (FDA) has approved the use of a two-drug combination developed by researchers at Rational Therapeutics Institute (Long Beach, Calif) for the treatment of ovarian cancer.

"Although the majority of patients with advanced ovarian cancer will die of the disease, optimism is justified in view of the improved results of surgery followed by cisplatin and carboplatin based chemotherapy."

The FDA has approved Gemzar (gemcitabine HCl for injection, Lilly) in combination with carboplatin for the treatment of women with advanced ovarian cancer that relapsed at least 6 months after initial therapy.

EntreMed, Inc.'s lead drug candidate Panzem (2-methoxyestradiol or 2ME2) has received orphan drug status from the FDA for the treatment of glioblastoma multiforme. In vitro studies in glioma cell lines demonstrated Panzem's antiproliferative activity, and in vivo studies in a preclinical model of glioblastoma showed its antitumor activity, EntreMed said in a press release. Panzem is currently being investigated in a phase II trial in patients with glioblastoma multiforme at the Brain Tumor Center at Duke University Medical Center. The agent previously received orphan drug designation for the treatment of multiple myeloma and ovarian cancer.

A long-term, multicenter study has shown that the reduction in breast and ovarian cancer risk resulting from oophorectomy—the removal of the ovaries and fallopian tubes in women at genetically high risk for these diseases—varies according to the type of genetic mutation present. Specifically, women with mutations in the BRCA1 gene have a greater reduction in ovarian cancer risk following the surgery, while those with BRCA2 mutations have a larger decrease in breast cancer risk. The study results were presented in Atlanta at the American Society of Clinical Oncology annual meeting.

The FDA has approved Hycamtin (topotecan, GlaxoSmithKline) in combination with cisplatin for the treatment of women with late-stage (IVB) cervical cancer that surgery or radiation appears unlikely to cure. The agency acted on the basis of a single phase III trial that showed a significant 2.9-month survival advantage in women treated with the combination vs whose who received cisplatin alone.

Anemia is common in patients treated with chemotherapy for both solid and hematologic malignancies, contributing to fatigue and diminished quality of life and exposing them to the inherent risks of red blood cell transfusions. Erythropoiesis-stimulating proteins have been shown to increase hemoglobin levels, reduce the need for transfusions, and improve quality of life. The current practice guidelines recommend treating moderate to severe chemotherapy-induced anemia with erythropoiesis-stimulating proteins, but the risk of transfusions may be less with earlier intervention at higher hemoglobin levels. A review of the literature suggests that treating mild chemotherapy-induced anemia with erythropoiesis-stimulating proteins reduces the risks of transfusions and the development of more-severe anemia. Weighing the clinical evidence together with other clinical and economic considerations should provide greater insight into the benefits of treating mild anemia in patients treated with chemotherapy.

The FDA has granted Oxigene's combretastatin A4P (CA4P) orphan drug status for treatment of ovarian cancer. In a phase Ib trial, advanced ovarian cancer patients who had failed previous therapy showed a 67% response rate to CA4P plus carboplatin and paclitaxel, the company said in a news release. This combination is currently being evaluated in a phase II trial in women with platinum-resistant ovarian cancer.

A small molecule that inhibits the insulin-like growth factor 1 receptor (IGF-1R) has blocked the development of human colorectal tumors in mice, according to researchers from OSI Pharmaceuticals, Melville, New York.

OXiGENE, Inc, recently announced that the Office of Orphan Products Development of the US Food and Drug Administration (FDA) has granted orphan drug designation to the company's lead vascular-disrupting agent, combretastatin A4 phosphate (CA4P), for the treatment of ovarian cancer.
