2011 SGO Annual Meeting: Ovarian Cancer Abstracts Selected For Presentation

The March 2011 supplemental issue of Gynecologic Oncology sets forth the ovarian cancer and ovarian cancer-related medical abstracts selected by the Society of Gynecologic Oncologists for presentation at its 42nd Annual Meeting on Women’s Cancer™, which is being held in Orlando, Florida from March 6-9, 2011.

The Society of Gynecologic Oncologists (SGO) is hosting its 42nd Annual Meeting on Women’s Cancer™ (March 6–9, 2011) in Orlando, Florida. The SGO Annual Meeting attracts more than 1,700 gynecologic oncologists and other health professional from around the world.

In connection with this premier gynecologic cancer event, 651 abstracts, and 27 surgical films were submitted for consideration. After careful discussion and deliberation, the SGO selected 51 abstracts for oral presentation (27 Plenary session papers, 24 Focused Plenary papers, and 42 Featured Posters, presented in a new, electronic format), along with 227 for poster presentation. Of the 27 surgical films originally submitted, five films were selected for presentation during a featured Focused Plenary session.

The ovarian cancer abstracts listed below were obtained from the March 2011 supplemental issue of Gynecologic Oncology. Each abstract bears the number that it was assigned in the Gynecologic Oncology journal table of contents.

About Society of Gynecologic Oncologists (SGO)

The SGO is a national medical specialty organization of physicians and allied healthcare professionals who are trained in the comprehensive management of women with malignancies of the reproductive tract. Its purpose is to improve the care of women with gynecologic cancer by encouraging research, disseminating knowledge which will raise the standards of practice in the prevention and treatment of gynecologic malignancies, and cooperating with other organizations interested in women’s health care, oncology and related fields. The Society’s membership, totaling more than 1,400, is primarily comprised of gynecologic oncologists, as well as other related medical specialists including medical oncologists, radiation oncologists, nurses, social workers and pathologists. SGO members provide multidisciplinary cancer treatment including chemotherapy, radiation therapy, surgery and supportive care. More information on the SGO can be found at www.sgo.org.

About Gynecologic Oncologists

Gynecologic oncologists are physicians committed to the comprehensive treatment of women with cancer. After completing four years of medical school and four years of residency in obstetrics and gynecology, these physicians pursue an additional three to four years of training in gynecologic oncology through a rigorous fellowship program overseen by the American Board of Obstetrics and Gynecology. Gynecologic oncologists are not only trained to be skilled surgeons capable of performing wide-ranging cancer operations, but they are also trained in prescribing the appropriate chemotherapy for those conditions and/or radiation therapy when indicated. Frequently, gynecologic oncologists are involved in research studies and clinical trials that are aimed at finding more effective and less toxic treatments to further advance the field and improve cure rates.

Studies on outcomes from gynecologic cancers demonstrate that women treated by a gynecologic oncologist have a better likelihood of prolonged survival compared to care rendered by non-specialists. Due to their extensive training and expertise, gynecologic oncologists often serve as the “team captain” who coordinates all aspects of a woman’s cancer care and recovery. Gynecologic oncologists understand the impact of cancer and its treatments on all aspects of women’s lives including future childbearing, sexuality, physical and emotional well-being—and the impact cancer can have on the patient’s whole family.

A Potential Treatment For Ovarian Cancer – Claudin-3 Gene Silencing Using Small Interfering RNA

“… Ovarian tumors highly express two proteins, claudin-3 and -4. These proteins are associated with both an increase is cellular motility and survival of ovarian tumor cells.  Claudin-3 is also over expressed in breast and prostate tumors. This new therapy is targeting claudin-3 (CLDN3) using small interfering RNA (siRNA). More specifically, this team has developed a nanoparticulate, lipid-like delivery system for intraperitoneal delivery of siRNA to ovarian tumors. Tests of the therapeutic efficacy of CLDN3 siRNA in three different mouse models showed a significant reduction in tumor growth.  Additionally, these mice showed no ill side effects of the CLDN3 siRNA treatment. …”

“PAPER REVEALS POTENTIAL NEW TREATMENT FOR OVARIAN CANCER

Wynnewood, PA, February 9, 2009 – – – – – Ovarian cancer is the fourth most common cancer in women and has the highest mortality rate for gynecologic cancers because it is often diagnosed at an advanced stage. New effective therapies for the treatment of advanced stage ovarian cancer are urgently needed.

Today, a paper published in the Proceedings of the National Academy of Sciences (PNAS) by Dr. Janet Sawicki, Professor at the Lankenau Institute for Medical Research (LIMR), a team headed by Daniel G. Anderson, Ph.D. and Robert Langer, Sc.D. of the David H. Koch Institute for Integrative Cancer Research at the Massachusetts Institute of Technology (MIT) and David Bumcrot, Director of Research at Alnylam Pharmaceuticals, shows that a new therapy suppresses ovarian tumor growth and metastasis in preclinical studies.

Ovarian tumors highly express two proteins, claudin-3 and -4. These proteins are associated with both an increase is cellular motility and survival of ovarian tumor cells.  Claudin-3 is also over expressed in breast and prostate tumors. This new therapy is targeting claudin-3 (CLDN3) using small interfering RNA (siRNA). More specifically, this team has developed a nanoparticulate, lipid-like delivery system for intraperitoneal delivery of siRNA to ovarian tumors. Tests of the therapeutic efficacy of CLDN3 siRNA in three different mouse models showed a significant reduction in tumor growth.  Additionally, these mice showed no ill side effects of the CLDN3 siRNA treatment.

‘We are excited by the preclinical performance of these formulations, and are hopeful that the lipidoid-siRNA nanoparticulates developed here may enable new genetic therapies for ovarian cancer,’ said Anderson.

‘These findings offer new hope for a therapeutic treatment option for individuals with metastatic ovarian cancer and potentially other types of cancers that over-express CLDN3′, states Dr. Janet Sawicki.  ‘Our next step is to begin Phase I clinical trials to test for safety with hopes to bring this treatment to the patient in the next few years.’

This research was made possible through funding from the National Institutes of Health (NIH), the Sandy Rollman Ovarian Cancer Foundation of Havertown, PA, and Wawa.
