Research

Led by Professor Pradeep Tanwar, the University of Newcastle’s Global Centre for Gynaecological Diseases (GCGD) is the first of its kind to bring together academic and clinical leaders, industry partners, philanthropic and community organisations to advance translational research in gynaecological diseases, create greater awareness for women’s health and diseases, and provide outcomes that will guide patient care.

The centre aims to enhance and coordinate research in gynaecological diseases, promote the application of this research toward improving women’s health, and optimise the training of future researchers, educators, and clinicians in the field of gynaecological diseases.

Research Priority Areas

Ovarian Cancer

The silent killer, a leading cause of death in women. 

Poor understanding of its pathobiology, the lack of early detection tests, and significant chemoresistance of the late-stage disease are some of the key reasons for poor outcomes observed in patients.

We aim to develop: 

  1. An early detection test for ovarian cancer patients
  2. New, less-toxic and cost-effective therapeutic treatments against chemoresistant cancer
  3. Novel prevention strategies against ovarian cancer

Endometrial Cancer

Fourth most common cancer affecting women and the most common form of gynaecological cancer in the developed world. 

The incidence of endometrial cancer has been rising with a higher prevalence of obesity and increased life expectancy. At the same time, relative survival has not improved over the past decades.

We aim to develop:

  1. New conservative fertility-sparing treatments for young endometrial cancer patients
  2. Novel approaches to treat the late stage metastatic chemoresistant disease
  3. Unique blood-based biomarkers to diagnose the disease early before it spread outside the uterus.

Endometriosis

830,000+ Australian women and girls (190 million worldwide) are living with endometriosis.

Affects more than 10% of women of reproductive age, and approximately 50% of affected women experience severe chronic pelvic pain and infertility. Despite the profound adverse effects of this chronic condition on individual functioning and quality of life, diagnosis can take 5-12 years and there is no cure for endometriosis.

We aim to develop:

  1. Non-hormonal, non-surgical treatments for endometriosis
  2. Disease-specific biomarkers to diagnose the disease early
  3. Tools to predict endometriosis recurrence after surgical treatments.

Vulvovaginal Diseases

The ‘unhappy disease’ is the most common reason for gynaecological consultation 

  • About 30% of women with vulvovaginal diseases go without a diagnosis even after a complete evaluation using the most advanced testing methods. Even when a diagnosis is made, treatments are often ineffective, or the benefit is of short duration.
  • Patients experience significant physical and emotional problems yet vulvovaginal diseases remain unappreciated in the broader medical community and are sometimes even regarded as minor annoyance to women.
  • Regardless of the underlying cause, treatments for vulvovaginal diseases aim to control the symptoms rather than cure the condition, and in over 30% of cases, recurrence is common following the recommended treatment.

We aim to develop: 

  1. A scientifically rationalised approach for the management and treatment of vulvovaginal diseases.

Fibroids

Affects up to 70% of women during their reproductive years 

  • Represent a significant source of gynaecological and obstetrical problems. Despite the major health care burden posed by fibroids, very little is known about their cause or the best treatment strategies.

We aim to develop:

  1. A blood-based test that will be able to differentiate between active and static disease states, allowing stratification of patients for personalised management of their disease
  2. Non-surgical, non-hormonal treatments for fibroids

Research Impact

Ovarian Cancer and Endometrial Cancer

  • Developing an early diagnostic blood test for endometrial and ovarian cancer. Technology is patented by Professor Tanwar (PCT/AU2019/050281).
  • Breakthrough discovery of stem cells that are responsible for endometrial epithelial regeneration and act as the cell of origin of endometrial cancer, as published in Cell Stem Cell. The publication received widespread media coverage including the ABC, SBS News, Technology Networks USA, the Telegraph, Sydney Morning Herald. Recognised by Research Australia as one of the top 15 innovations nationwide featuring a two-page story in INSPIRE magazine.
  • Described how hormones drive the growth of ovarian and endometrial cancers and provided scientific evidence showing that contraceptive use reduces the risk by 40% of ovarian & endometrial cancers, as funded by Ovarian Cancer Research Foundation.
  • Multiple national and international clinical trials on ovarian and endometrial cancers.

Endometriosis

  • Developed the world first avatar model of endometriosis from patients, which allows us to screen drugs for this disease.
  • Developing and validating a blood test for the early diagnosis of endometriosis.
  • Identified a mutant cell type that causes endometriosis in women.
  • Dr Pravin Nahar is a leading expert in laparoscopic/hysteroscopic surgery and training supervisor for the registrars. Drs Pravin Nahar and Angela Dunford are involved in care of endometriosis and fibroid patients.

Vulvovaginal diseases

  • Developed a patented vaginal organoids drug testing platform. Related research published in Cell Reports 2020.
  • Developed clinical guidelines for the interpretation of nondiagnostic vulvar biopsies and clinicopathologic diagnostic criteria for vulvovaginal lichen planus.
  • Demonstrated how topical corticosteroids reduced recurrence of vulvar squamous cell carcinoma in women.

Fibroids and Pelvic Pain

  • Developed a complete compendium of proteins in human uterine fibroids.
  • Exploring the next generation of treatments for uterine fibroids.
  • Professor Hondermarck authored a landmark review article in a highly prestigious journal Cell describing the current state of cancer neuroscience.
