Global Influence of our Research

Research never happens in isolation. It draws on, inspires and informs other studies. We can see the growing international influence of our research in two ways - citations of our research output and invitations to speak at international conferences. For a complete listing of QCGC Research grants and publications visit Professor Obermair's UQ profile here.

Research Output

Imagine Trial

Background:

The IMAGINE Trial was developed to test a model for training gynaecological surgeons in laparoscopic hysterectomy rather than traditional open abdominal surgery. This followed outcomes from previous QCGC Research studies that showed 40% of hysterectomies were performed with traditional open abdominal surgery (LACE Trial ) and that the main impediment to gynaecological surgeons changing their practice was a lack of training opportunities to gain the advanced surgical skills needed to conduct less-invasive keyhole hysterectomy (LIgHT Study). It was expected that once surgeons were equipped with skills to perform laparoscopic surgeries, better outcomes would be achieved for women and save costs to the health system.

feMMe Trial

In March 2021, QCGC Research Director, Professor Andreas Obermair, shared the findings of the feMMe trial to the world-wide gynaecological oncology community, at the Society of Gynecologic Oncology’s (SGO) Virtual Annual Meeting on Women’s Cancer .

The feMMe trial investigated whether women with endometrial cancer could be treated less invasively through the use of a common intra-uterine device to reduce the need for surgery and in some women, preserve their fertility. 165 women from 16 sites across Australia and New Zealand were enrolled in the study.

The findings shared included:

  • 82% of women with endometrial hyperplasia with atypia (a precursor to endometrial cancer) and 42% of women with endometrial cancer responded to the new non-invasive treatment;
  • The new treatment was more successful when combined with weight loss (67% response rate); and
  • Side effects from the new treatment were few and far between.

The results will benefit women around the world, diagnosed with endometrial hyperplasia with atypia or a well-differentiated endometrial cancer who have an unreasonably high risk of complications from endometrial cancer surgery; and younger women diagnosed with early stage cancer who wish to retain fertility to complete their families.

LACC Trial

This trial is a good example of QCGC Research's global influence. LACC is a worldwide trial aiming to determine the best surgical treatment option for women experiencing early stage cervical cancer via Minimally Invasive Surgery (laparoscopic (key-hole) or robotic radical hysterectomy) vs the traditional open-radical hysterectomy approach.  

In contrast with endometrial cancer, results of the 10-year LACC Trial, suggest that laparoscopic or robotic radical hysterectomy for cervical cancer is more likely to result in disease recurrence and reduced survival rates than open abdominal surgery.  

As a result of this trial, NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for the treatment of cervical cancer has been revised to reflect the findings of this trial. NCCN Guidelines are widely recognised and used as the standard for clinical policy in oncology by clinicans worldwide.

In November 2018, our group published a paper in the New England Journal of Medicine comparing laparoscopic with open radical hysterectomy for early-stage cervical cancer.

LACE Trial

The LACE trial showed that total laparoscopic surgery had significant benefits for patients including lower rate of postoperative adverse events, shorter length of hospital stay, better quality of life as reported in Lancet Oncology and European Journal of Cancer. Cost-effectiveness analyses was reported in the BMJ, showed that a decision to invest in laparoscopic surgery was cost effective for health funders in 98% of the time. This clinical trial remains the world's most influential randomised study in the surgical treatment of endometrial cancer, and its results demonstrated that laparoscopic surgery should be the first line therapy, a result that has become embedded in national and international treatment guidelines (reach). This outcome had a major effect on the world-wide use of laparoscopic surgery for patients with endometrial cancer and is estimated to save the health care system $3000 for each operation that can be done laparoscopically since the results of the trial were published in JAMA in 2017.

LiGHT Trial

This study surveyed over 2300 women in Queensland who had a hysterectomy in the past. It was very interesting to find that 96% were happy they had the hysterectomy and only 4% reported they regretted the decision. Most women followed the advice of their doctor with regards to the type of hysterectomy suitable for them. Very few women sought a second opinion. Recovery was good for most women, with those receiving laparoscopic or vaginal hysterectomy reporting quicker recovery than those who had an open abdominal hysterectomy. These women took up to 6 months to recovery completely.
