Fellowship title
How does impaired energy production cause prostate cancer
Fellow Prof Aleksandra Filipovska
Institution The University of Western Australia
Research description 

Prostate cancer is one of the six most common cancers in the world; the incidence rates of this cancer vary due to genetic and environmental factors. Several genes are responsible for the development of sporadic and, in particular the gene ELAC2 is one of the most relevant candidate genes for prostate cancer. Many mutations have been identified in ELAC2 that predispose to prostate cancer. Unfortunately, it is not known how these mutations cause prostate cancer. The team has generated mice containing ELAC2 mutations and develop prostate malignancy that closely mirrors the prostate cancer pathogenesis in humans.

Prostate-specific antigen (PSA) is the only screening biomarker for prostate cancer but because it is not always produced by malignant cells, this biomarker is not entirely reliable since it can generate false results. There is an urgent need for identification and validation of biomarkers and prostate cancer genes. This study will be the first to address both of those needs.

Fellowship title
Developing blood tests to guide treatment of melanoma
Fellow A/Prof Elin Gray
Institution Edith Cowan University
Research description 

Melanoma now represents a significantly increased proportion of cases in clinical oncology departments, with melanoma incidence increasing worldwide and in Australia. Once melanoma has spread through the body, the average (or usual or expected) survival is 6 to 9 months, with 5-years survival of less than 40%. The recent implementation of new treatments has improved patient outcome and survival. However, there is an urgent need for a better test to guide the doctors while they are treating their patients.

The proposed studies aim to develop tests that can be done from a blood sample. These tests make use of new technologies to test for evidence of markers derived from the growth (tumour) found in the blood of patients with melanoma. These markers could serve as a guide of what is going on in the cancer. A/Prof Gray aims to demonstrate that in melanoma, these tests can effectively and accurately provide the oncologists with information about the growths, for them to take better informed treatment decisions.

Fellowship title
Improving psychosocial support and education for patients diagnosed with brain or head and neck cancer and their carers
Fellow A/Prof Georgia Halkett
Institution Curtin University
Research description 

Being diagnosed with brain or head and neck cancer is distressing as it is often life threatening has a large impact on people physically and/or mentally. Hence, it is essential that education and support programs are developed and tested to reduce distress and unmet needs for people diagnosed with these cancers and their carers.

Two programs have been developed:
1. RT Prepare program: This program focuses on preparing people for radiotherapy. Little research has been conducted in this area. This teams work in preparing people diagnosed with breast cancer for radiotherapy is recognised internationally; however, this program needs to be refined for people with other cancers. Receiving radiotherapy for brain cancer or head and neck cancer may cause distress due to the head mask they must wear to stop them moving and side effects they might experience. People receiving radiotherapy for head and neck cancer are at risk of severe skin reactions, dry mouth, oral discomfort, mouth ulcers, infections, difficulty chewing and swallowing, impaired taste and extreme weight loss. People receiving radiotherapy for brain cancer may fear side effects such as headaches, hair loss, nausea, extreme tiredness, hearing loss, skin changes, speech difficulties and seizures. Education and support provided by the radiotherapy team before treatment is likely to reduce their anxiety and help them manage side effects.

Research methods for this program will include interviews, development and testing of the education packages and a large scale clinical trial. Main outcomes will include anxiety and distress, concerns and knowledge about radiotherapy and how prepared they feel for treatment.

2. Carer's Education and Support Program: This program focuses on improving carer's confidence to look after their loved one after a cancer diagnosis and reducing their level of distress. This research focuses on carers of patients diagnosed with brain cancer or head and neck cancer because these groups would benefit most from extra support. If carers are unable to support their loved one, it is likely that the person with cancer may need additional emergency room visits or hospital admissions. During the program a nurse conducts a telephone assessment, visits the carer at home, provides an individualised resource manual and regular telephone follow-up for 12 months. This program is currently being tested in a randomised controlled trial with carers of people with brain cancer. It needs to be adapted and tested for carers of people with head and neck cancer.

Research into these two programs is essential to improve the education and support provided to individuals and their carers following a diagnosis with either brain cancer or head and neck cancer. The team will also determine the cost of providing these programs and the impact they have on overall healthcare costs.

Fellowship title
Improving detection and therapy in treatment-resistant cancers
Fellow Dr Juliana Hamzah
Institution Harry Perkins Institute of Medical Research
Research description  This research program will potentially benefit patients suffering from treatment-resistant cancers such as triple negative breast cancer and liver cancers. Approximately one in eight Australian women will be diagnosed with breast cancer before the age of 85. Similarly, liver cancer is the third leading cause of death in Australia. Treatment options that include conventional chemotherapeutics are currently ineffective.

Dr Hamzah has identified tumour stiffness as the major problem in breast and liver cancers. Tumour stiffness is caused by over-production of non-cellular matrix components that protects the tumour cells from being accessible to anti-cancer drugs. Consequently, the stiffer the tumour matrix, the more resistant it is to drug therapy.

Recently this team has developed a new medication and treatment to specifically dissolve tumour stiffness. Degradation of matrix stiffness effectively exposes the tumour cells to anti-cancer medications. Dr Hamzah's goal is to explore the use of this drug to treat breast and liver cancers.

Fellowship title
Identifying new effective treatments for mesothelioma
Fellow Dr Willem Joost Lesterhuis
Institution The University of Western Australia
Research description  This research focuses on mesothelioma, a fatal cancer of the lining of the lung, caused by exposure to asbestos. Western Australia has the highest incidence of this cancer in the world, because of the mining, transport and high use of asbestos here.

Chemotherapy has some effect in a number of patients, but always short-lived. Immunotherapy, which boosts the immune system against cancer, appears promising with some patients showing a remarkable decrease in cancer burden, but unfortunately this does not happen very often. The outcome for people with mesothelioma has not improved in more than a decade.

Firstly, the intention is to investigate whether chemotherapy and immunotherapy are more effective when they are used in combination. The idea has always been that chemotherapy has only harmful effects on the immune system, but research shows that some of these drugs may actually have beneficial effects. However, it's not known which chemotherapeutics can be best combined with immunotherapy. Here, the intention is to test all different classes of cancer chemotherapy for their ability to work in combination with immunotherapy, and study the mechanisms that determine the combined anti-cancer effect.

Secondly, the intention is to investigate why some people with cancer who are treated with immunotherapy have a full regression of their cancer, while others have no response to the therapy at all. By investigating which cells and molecules are responsible for the anti-cancer effect, and by subsequently reinforcing those processes using already available drugs, The aim to increase the cure rate.

Lastly, the intention is to investigate which cells and molecules are involved in the fast growth of mesothelioma, and to aim to identify drugs that stop this process.

This will be conducted using mesothelioma animal models, and samples from mesothelioma patients. Since many of the drugs tested are already in clinical use, the findings can be rapidly translated into the clinic; for some of the drugs this may be within 5 years.

Fellowship title
Towards targeting treatment-resistant cancer cells to prevent relapse in childhood leukaemia
Fellow Dr Sébastien Milange
Institution Telethon Kids Institute
Research description 

Acute leukaemia is the most common type of cancer seen in children (>200 cases per year in Australia). Although treatments and outcomes have improved remarkably, leukaemia remains the second highest cause of death by cancer in children. Furthermore, many children still suffer from treatment toxicity or develop relapse. These clinical features are exacerbated in children with Down Syndrome (DS).

This study aims to identify the treatment-resistant cells that are responsible for relapse, and discover new methods to destroy them. The study will use animal models to reproduce the standard therapy used in clinics and add two promising drugs to destroy these cells. The study will also look for agents that improve the efficacy of these two drugs, and extend to non-DS children with leukaemia that have a similar molecular makeup to DS children. Outcomes from this study are to develop new treatments for clinicians to improve the quality of care and long-term survival of West Australian children with leukaemia.

Fellowship title
Empowering the immune system to attack melanoma and other advanced cancers
Fellow Dr Jason Waithman
Institution Telethon Kids Institute
Research description  Melanoma is Australia's 3rd most common cancer resulting in the 9th highest number of cancer-related deaths. There is traditionally poor prognosis once it spreads. New treatments that harness the immune system can cure many people with advanced melanoma. However, there is urgent need to help patients that aren't responding to these immunotherapies. To address this, the research strategy focuses on the following aims: to improve the body's immune system to fight cancer and thereby increase the number of patients surviving; to help the immune system to better detect and attack cancer cells, which leads to saving lives; to understand how the immune system can be improved to stop the spread of melanoma cancer in the brain - this is critical as it is a very poor prognosis once in the brain; and to understand how specific immune cells might offer protection from skin cancer and keep tumours dormant, thereby directly saving lives.

The purpose of this research is to gain more insight into how the immune system interacts with cancer cells and develop new ways to make the immune system fight cancer. To do this the research work focuses on T cells, which recognise and marshal an attack against diseased cells.

The team are engineering T cells with additional capabilities, making them more able to eradicate tumour cells. They are also generating a vaccine that causes T cells to multiply so they can overwhelm cancer cells and eliminate them.

As melanoma frequently spreads to the brain the team are also investigating how an immune response is directed against tumours within the brain and testing whether the new therapies are effective.

Also, tumours can remain dormant for prolonged periods of time and patients can live normally. Little is known about how this occurs. The team will identify the role of the immune system in tumour dormancy, which will lead to new therapeutic approaches that convert aggressive cancer into a stable chronic condition.
Through this work the intention is to identify multiple ways to drive and enhance T cell immunity against cancer. This research will save lives by improving the overall survival rate, especially in patients currently deemed terminal and non-responsive to immunotherapy.
