Endometrial cancer, which starts in the lining of the uterus, is the third most common gynecologic cancer, striking more than 47,000 American women every year, particularly the obese. "Total hysterectomy, sometimes with removal of lymph nodes, is the most common treatment for this type of cancer.
But women who are morbidly obese or who have cardiac risk factors are not good candidates for surgery," said Dr. Sharad Ghamande, a gynecologic surgeon and oncologist at the GHSU Cancer Center, Chief of the Section of Gynecologic Oncology at the Medical College of Georgia, and principal investigator on the study.
For two years, Ghamande and his team followed a small group of high-risk patients with early-stage endometrioid adenocarcinoma, a common subtype of endometrial cancer, and those with atypical endometrial hyperplasia, or thickening of the uterine lining, which can lead to cancer. Patients were treated with an intrauterine device that releases the progestin levonorgestrel, successfully used for the past decade as a contraceptive.
The endometrial stripe, or thickness of the endometrium, was measured with transvaginal ultrasound before the study and at the three- and six-month marks. The stripe's progressive thinning at each stage demonstrated the effectiveness of the treatment. Subsequent endometrial biopsy found reversal of abnormal cell growth, known as neoplastic changes, in all patients.
Ghamande's group also analyzed 13 published studies and found a complete pathological response in 91.3 percent of cases, with no progression of disease, confirming their findings. The study also validated use of transvaginal ultrasound, commonly used to diagnose endometrial cancer, as a useful follow-up tool in assessing endometrial cancer treatment.
"Thirty to 35 percent of women with hyperplasia will go on to develop endometrial cancer, and in 30 percent of these cases, women will present with a co-existing cancer," said Ghamande. "Traditional treatments can result in postoperative complications and morbidity, not only in patients at high risk. But we may succeed in establishing a lower-risk and more cost-effective way of managing this cancer in all women."
"Identifying better treatments for cancer is the most important goal of our cancer research center," said Dr. Samir N. Khleif, Director of the GHSU Cancer Center. "Studies such as Dr. Ghamande's are changing the landscape of cancer care today, both here in Georgia and around the world."
Ghamande and Dr. Cinar Aksu, a GHSU Cancer Center fellow, presented the study results on Tuesday during the International Gynecological Cancer Society's 14th biennial meeting. Dr. Michael Mcfee, a gynecologic oncologist, and fellow Dr. Steve Bush, both of the GHSU Cancer Center, co-authored the study.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
