      PDF [18,9 KB]  From [www.wcn.org]  Last viewed: 07.09.2006
Updated January 2002 What is gynecologic cancer ? Gynecologic cancer is the uncontrolled growth and spread of abnormal cells originating in the female reproductive organs, including the cervix, ovaries, uterus, fallopian tubes, vagina and vulva. What causes gynecologic cancer ? Biomedical research has discovered that some genes, called oncogenes and tumor suppressor genes, promote the growth of cancer . You can acquire these genetic mutations during life (e.g. through smoking, aging or environmental influences) or you can inherit these mutations from your parents or grandparents. Can gynecologic cancer be prevented? Diet, exercise and lifestyle choices play a significant role in the prevention of cancer . Additionally, knowing your family history can increase your chance of early diagnosis and can help you take action towards prevention. Regular screening ...

Genetic Testing for Breast and Ovarian Cancer May 2002 Jennifer Silverman Stanford University, Stanford CA 94309 USA E-mail: jsilverman@stanford.edu Abstract Genetic testing for breast and ovarian cancer has been publicly available since the mid-1990 discovery of two breast/ ovarian cancer susceptibility genes named BRCA1 and BRCA2. Although many professionals say that genetic testing may be the best available preventative medicine breakthrough, controversy abounds over whether the medical benefits of BRCA1/2 mutation testing outweigh the psychological and financial costs. This study uses three models to analyze 104 women’s responses to a self-designed questionnaire: a logit regression model, an ordered probit regression model, and a cost effectiveness model. The regression models use questionnaire responses to learn how the benefits and costs of genetic testing affect a woman’s decision to ...

49 SURGERY FOR OVARIAN CANCER DAVID M. GERSHENSON and J. TAYLOR WHARTON Ovarian cancer , one of the most challenging diseases facing gynecologic oncologists, is currently the second most common malignancy of the female genital tract in the United States. According to the American Cancer Society, 1 25,200 new cases of ovarian cancer and 14,500 deaths from the disease in the United States were esti- mated for 1999. Surgery remains the cornerstone in the management of ovarian cancer . This chapter reviews current prac- tices in surgical management, including primary sur- gery, secondary procedures, second-look laparotomy, and surgery for complications of ovarian cancer and its therapy. Although many of the concepts and principles apply equally to all three broad categories of ovarian cancer —epithelial, germ cell, and sex cord–stromal— ...

Fox Chase Cancer Center 2001 Scientific Report Drug Resistance in Model Systems. Hamilton, Ozols, Selvakumaran, Williams, Bao, Bingham, Schoenberger The aggressive therapy of ovarian cancer includes, as a cornerstone, cisplatin or one of its analogs. Thus, our investigations of the mechanisms of drug resistance in ovarian can- cer cells primarily involve the study of mecha- nisms of platinum resistance. One approach we have used to study this problem has been to produce cisplatin-resistant ovarian cancer cell lines by exposure of drug sensitive cell lines to increasing concentrations of cisplatin. The most resistant of these variants, C200, is nearly 500-fold resistant to cisplatin. These cell lines show a complex cross-resistance phenotype typical of clinical ovarian cancer ; they are cross-resistant to carboplatin, tetraplatin, mel- phalan, mitomycin C, adriamycin, ...

W OMEN AT HIGH RISK for ovarian cancer — the most lethal gynecological malig- nancy—can now benefit from cutting- edge research that has yielded several methods for early detection, all of which are available at NYU Medical Center. “Until recently, there were no tests to accurately diagnose ovarian cancer or disease confined to the ovary, much less predict the development of any cancer ,” explains David A. Fishman, M.D., Professor of Obstetrics and Gynecology, and Director of Gyneco- logic Oncology. “Today, based on our research employing new computer sophistication and ultrasensitive technol- ogy, we can look beyond cells to genes and proteins for abnormalities that may indicate precancerous changes.” As Director of the National Cancer Institute’s (NCI) National Ovarian Cancer Early Detection Program ( NOCEDP ), Dr. ...

OVARIAN CANCER AWARENESS MONTH WHEREAS: Ovarian cancer has long been called a “silent killer,” because it occurs in an organ deep in the pelvis and produces vague symptoms that may be dismissed; and WHEREAS: Recent studies have identified factors that put women at higher risk of developing ovarian cancer , such as a family history of breast and ovarian cancer , no pregnancies or infertility, no history of oral contraceptive use, or the use of high-dose estrogen for long periods without progesterone; and WHEREAS: Early detection remains the most valuable weapon against ovarian cancer ; however, there is not a simple early detection method. Subtle symptoms include pelvic and abdominal pressure; bloating; pain, swelling or discomfort; unexpected weight gain or loss, especially weight gain in the abdominal area; gastrointestinal problems; and back pain and fatigue. ...

MECHANISMS OF DISEASE 572 THE LANCET • Vol 359 • February 16, 2002 • www.thelancet.com Background New technologies for the detection of early- stage ovarian cancer are urgently needed. Pathological changes within an organ might be reflected in proteomic patterns in serum. We developed a bioinformatics tool and used it to identify proteomic patterns in serum that distinguish neoplastic from non-neoplastic disease within the ovary. Methods Proteomic spectra were generated by mass spectroscopy (surface-enhanced laser desorption and ionisation). A preliminary “training” set of spectra derived from analysis of serum from 50 unaffected women and 50 patients with ovarian cancer were analysed by an iterative searching algorithm that identified a proteomic pattern that completely discriminated cancer from non- cancer . The discovered pattern was then used to classify an ...

November/December 2001, Vol.8, No.6 Supplement 1 Cancer Control 19 The treatment of advanced ovarian cancer has evolved over the past 20 years. Although effective early diagnosis continues to be elusive and the man- agement of relapsed ovarian cancer does not offer a cure, new therapeutic advances offer many women longer disease-free intervals and improved quality of life with disease. The focus of this program has been to explore the management of advanced ovarian cancer in ways that would promote optimum disease response to various antitumor agents and maximize quality of life during the disease trajectory. For the Nonresponsive or Platinum- Refractory Patient In patients who either do not achieve a clinical response to their initial therapy or who progress while on primary therapy and are considered refrac- tory to platinum,it is clear that standard therapy ...

Key Points : Family history is an important tool in the assessment of breast and ovarian cancer risk Women are concerned about breast cancer and often over-estimate their risk. They may view themselves as candidates for genetic testing when their likelihood of a positive test is minimal. BRCA1/2 mutations are rare and there are few data to assess the outcome benefits of interventions to reduce risk Testing for BRCA1/2 is mentioned frequently in the medical and lay press.

86 12. OVARIAN CANCER SCOPE OF THE PROBLEM Ovarian cancer is the seventh most common malignancy diagnosed in Connecticut women, accounting for 3.5 percent of invasive cancers. It is the leading cause of death from gynecological malignancies, accounting for about 5 percent of cancer deaths among Connecticut women or 200 deaths each year. Stage at Diagnosis and Relative Survival Rate Ovarian cancer has the worst prognosis of any gynecological cancer , because it produces no symptoms until it is at an advanced stage. In the United States, cancer incidence and survival rates are reported through the SEER program (see Appendix A). Between 1992 and 1997, 26 percent of ovarian cancers were localized at diagnosis, where the five-year relative survival rate was 95 percent, 10 percent had spread regionally by the time of diagnosis, where ...

Ovarian Cancer What Is Cancer ? Cancer is a group of many related diseases. All forms of cancer involve out-of-control growth and spread of abnormal cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person's life, normal cells divide more rapidly until the person becomes an adult. After that, normal cells of most tissues divide only to replace worn-out or dying cells and to repair injuries. Cancer cells, however, continue to grow and divide, and can spread to other parts of the body. These cells accumulate and form tumors (lumps) that may compress, invade, and destroy normal tissue. If cells break away from such a tumor, they can travel through the bloodstream, or the lymph system to other areas of the body. There, they may settle and form "colony" tumors. In their new location, the cancer cells continue growing. The spread of a tumor to a new site ...

51 T he presence of simultaneous carcinomas involving both the ovary and uterine corpus is rel- atively uncommon, and only 0.7–10% of patients with epithelial ovarian or uterine cancers have been found to have simultaneous tumours in large series. 1 However, these synchronous tumours represent a diagnostic and ther- apeutic challenge, particularly if they have a similar histol- ogy. Here we present the case of a 34-year-old woman with endometrioid cancers of both ovaries and adenocarcinoma of the uterus. C A S E RE POR T The patient was referred to our hospital because of metror- rhagia and lower abdominal pain of six months duration.

  [297] 155-16 (4-17-99) Blood test may screen for ovarian cancer
      PDF [40,1 KB]  From [www.sciencenews.org]  Last viewed: 07.09.2006
Ovarian cancer usually grows for about 2 years before it produces symptoms, a large British study indicates. The delay explains why doctors diagnose only about one-fourth of cases before the disease has spread to other tissues, according to the researchers. A sensitive blood test, used in the study to indicate when disease originated, could be widely employed to screen postmenopausal women for ovarian cancer , the researchers assert. Such screening could detect more cases early, when treatments are most effective, they say. When the cancer is detected while confined to the ovaries, 90 percent of women survive at least 5 years, says Robert C. Bast Jr., an oncologist at the University of Texas M.D. Anderson Cancer Center in Houston. Only 15 to 20 percent of women in whom the cancer has spread beyond the pelvic cavity survive 5 years. In the new study, a team led by Ian J. Jacobs of St. Bartholomew’s Hospital ...

  [298] 152-01 (7-5-97) Ovulation cycles linked to ovarian cancer
      PDF [40,2 KB]  From [www.sciencenews.org]  Last viewed: 07.09.2006
For the female body, ovulation is hard work. An ovary secretes hormones, produces an egg, thrusts it through a wall of tissue, and afterward repairs the rupture. Four weeks later, the process repeats. Scientists have suspected that the frequency and rigor of tissue rebuilding can lead to ovar- ian cancer because, after each ovulation, the manufacture of new cells requires synthesis of DNA. This cell proliferation is thought to open the door to mutations in the p53 gene, which produces one of the body’s natural cancer fighters. Now, a new study bolsters this incessant-ovulation theory (SN:10/31/92, p. 298) and its corollary that pregnancy, breast feeding an infant, or taking oral contraceptives lessens a woman’s cancer risk by giving her welcome rests from ovulation and easing wear and tear on the ovaries. The key element in this theory is the p53 gene, which normally blocks cell division when a cell has sustained ...

Reducing the risk of ovarian cancer Birth control pills lessen risk of ovarian cancer even among women carrying harmful muta- tions in one of the so-called breast cancer genes, BRCA1 and BRCA2, a new study finds. A team led by researchers at the University of Toronto and Women’s College Hospital in Toronto compared 207 patients who had ovarian cancer and a mutated BRCA gene with 161 of these women’s sisters who didn’t have the cancer . The patients averaged 54 years old and the sisters 52 years old. Half of the patients reported having used birth control pills at some point in their lives, on average for 4 years. Among the 50 sisters without cancer who carried the BRCA1 mutation, 77 percent had taken oral contraception, averaging 5 years on the pill. Only three of the sisters showed the BRCA2 mutation. The data demonstrated that risk of ovarian cancer decreases as years of birth-control pill ...

Gene therapy for breast, ovarian cancer A novel gene therapy technique may one day hold out promise for women with breast or ovarian cancer . Naoto T. Ueno of the University of Texas M.D. Anderson Cancer Center in Houston and his colleagues knew that 20 to 30 percent of ovarian and breast cancer patients have a gene, called HER-2/neu, that is hyperactive. They also knew that women with this overactive gene tend to have a poor therapeutic outlook. “The cancer is aggressive,” Ueno says. The team wanted to see if it could slow the cancer by countering the action of HER-2/neu in cancer cells. To do that, the researchers turned to another gene, E1A, which is thought to work by turning off HER-2/neu. They had previously used the E1A gene to treat mice with ovarian cancer . The Texas team recruited 12 people with advanced ovarian or breast cancer . Each recruit received weekly injections ...
