April 2016 research report

CIKA is committed to providing funding for research into solid tumours


April 2016 research report - Cancer in Kids @ RCH - CIKA

Dr Louise Ludlow was the guest speaker at The April Macedon Ranges Focus Group luncheon on 8 April 2016. Louise established and now manages the Children's Cancer Centre Tissue Bank and her talk centred around her background and the research she has undertaken at the Murdoch Children's Research Institute. Here is a transcript.

I started working at the Murdoch Children's Research Institute three years ago in the role of Tissue Bank Coordinator. I come from a research background having completed my PhD at The Peter MacCallum Cancer Centre in 2005. I studied a family of genes involved in cancer immunology. It was five years of hard work and I enjoyed the excitement of making new discoveries. After completing my PhD I took up a three year role at Northwestern University in Evanston just outside Chicago. Here I investigated the ability of viral proteins to escape the immune system. The research environment was competitive and work ethic was fierce. It was a wonderful life experience but terribly cold in the winter!

Upon return to Australia I took up a four year position at The Burnet Institute and The University of Melbourne investigating the immune response to malaria and HIV infection. In my experiments I used blood cells collected in PNG and discovered the incredible value of using banked tissue.


My role as Tissue Bank Coordinator has provided a fantastic opportunity to expand upon my laboratory skills and to meet dedicated and inspirational people like yourselves. The role has provided many challenges such as gaining our ethical approval to start the Tissue Bank, communicating with gruff surgeons and overworked oncologists!

Our Tissue Bank has been in operation for two years. During this time we have consented just under five hundred patients and banked over a thousand samples. We have banked many rare and interesting solid tumour specimens along with blood and bone marrow samples.

Tissue banking is a highly collaborative process requiring great levels of communication and networking. Over fifty staff including consultants, surgeons, haematologists, oncologists, specialist pathologists, researchers and a roster of on-call scientists ready to receive and process tumour material on any day at any time make up this team. Our process begins with consenting the patients and their families in the clinic or bedside. We then collect and process the samples in our laboratory on Level 5 South.

All research projects investigating childhood cancer rely on using tissue samples removed from patients in the operating theatre or in the clinic during the normal course of clinical investigation and treatment.

The role has provided experiences that have put life in perspective. Meeting the mother and brothers of a young girl who passed from a rare and incurable brain tumour. Her capacity to donate this tumour for research. My joy is showing this family the immortalized cell line under the microscope which I generated. Knowing this tumour tissue and cell line will be used to make a difference in the fight against these brain tumours. Seeing the amputated hand of a child containing a large muscle tumour. Knowing that this tissue we bank will make a difference.

Through the devastation and unbearable grief this disease causes there is a shining light that is research. Our Tissue Bank is an incredibly important resource for cancer research and is a core part of the Children’s Cancer Centre. Our vision is that through research we can not only improve treatment but contribute to implementing a personalised model of care within the RCH. Banked samples are already being utilised in a number of research studies being conducted on campus and samples have also been dispatched to contribute to collaborative international studies.


I would now like to take the opportunity to explain two projects that have used samples provided by the Tissue Bank.

The first study
involves investigating pilocytic astrocytoma and is the work of a PhD student Alex Sexton-Oates working with Prof., Richard Saffery. PA is the most common brain tumour in children under the age of eighteen. In fact one in five children diagnosed with a brain tumour have a PA. PA has an excellent survival rate and treatment consists of surgical removal of the tumour. Radiotherapy and chemotherapy may be given in cases where the tumour cannot be completely removed. Extra treatment may also be given if the PA grows back after surgery, this is called ‘recurrence’ and happens is up to 30% of children.

Children may be left with long-term negative effects on their brain function and mental health. These long-term effects are due to both the treatment children receive and the location of their brain tumour. The research is asking two questions. What is different about PAs that grow in difference parts of the brain? What is the difference between PAs which do not recur after surgery and those which do?

Alex used a new technique called a methylation array to analyse a group of PA. Through this technique she was able to identify the tumours which recurred. This work will lead to identifying new treatments for the more aggressive PAs and the ability of predict at diagnosis which children will need to return for regular brain scans.


The next project involves understanding chemotherapy-induced heart disease. We have processed nearly three hundred blood samples toward this project which is being led by Dr Rachel Conyers, an oncologist together with Dr David Elliot, an MCRI researcher.

A side effect of a number of valuable chemotherapeutic drugs is heart damage. Cancer survivors treated with these drugs are nine times more likely than average to develop heart failure. However, only 20-30% of patients are susceptible to chemotherapy-induced heart failure. The aim of this research is to find out why some patients are resistant and some are sensitive to this toxicity. The study aims to genetically profile over 150 childhood cancer survivors and develop stem cell technology. The goal is to set up a clinically applicable tool to predict patient sensitivity to chemotherapy. This will enable a more tailored chemotherapy to patients resulting in less cardiac toxicity.

The stem cell technology involves taking the white cells from peripheral blood and reprogramming them to an embryonic stem cell-like state. These cells are then differentiated to cardiomyocytes which beat in culture.


There are two additional aspects of the Tissue Bank:

We generate neurosphere cell lines from high grade brain tumours. These cell lines represent valuable tools for understanding tumour biology and for testing novel drugs before their use in children.

The CCC has an active research arm in international collaborative large scale clinical trials. The CCC Tissue Bank provides tissue processing to enable patient participation in international clinical trials.


MCRI is a great place to work! The director of the CCC, Francoise Mechinaud, has been the driving force behind establishing the bank and Prof., Richard Saffery provides guidance and advice. There are many interesting areas of research, many dynamic and dedicated researchers. Some areas of research include expansion of genomics for early diagnosis and improved treatment, rotavirus vaccine work, development of an inhaled vaccine device.

Much of this research at MCRI could not be carried out without philanthropic funds. We are extremely grateful for your support.

The Tissue Bank is an essential component of the Children’s Cancer Centre’s mandate to provide best possible care for current and future patients. It enables clinicians to offer patients the opportunity to participate in international clinical trials. CIKA supports patient enrolment in these clinical trials by supporting the Tissue Bank Coordinator, Dr Louise Ludlow, who processes and dispatches the tissue, blood and bone marrow samples necessary for participation in the trial.
