Liquid Biopsy: The future of predicting breast cancer recurrence

Bruce Abel - Wednesday, October 01, 2014

Dr. Ben Green Is leading a research project looking at new methods for predicting and detecting breast cancer recurrence via blood test, in what is being labeled ‘Liquid Biopsy in Breast Cancer’.

The project is being conducted as part of a joint effort between University of Queensland Centre for Clinical Research (UQCCR), Queensland Institute of Medical research (QIMR) Berghofer Centre and the Breast cancer specialists at the Royal Brisbane and Women’s’ Hospital (RBWH) where Dr. Green works as part of the Breast Surgical team.

Overall Breast cancer is very well treated in Australia. 5-year survival rates are around the 85% for all patients. Unfortunately there are still a large number of women who are diagnosed with breast cancer who will develop spread of the disease (metastasis) and eventually pass away as a result of the breast cancer. This is despite undergoing extensive surgery and a combination of radiotherapy, chemotherapy, hormonal therapy and Herceptin treatment.

Currently there is no possible way to detect and predict which patients are failing treatment and going to develop spread of the disease until it has already occurred and can be seen on a Mammogram, ultrasound or CT scan.

The research Dr. Green is leading is looking at the possibility of being able to detect the return of a patient’s breast cancer long before it is detected on imaging. This will provide the opportunity to begin a new treatment prior to the spreading disease having a chance to take hold and grow.

Dr. Green is particularly interested in markers in a patient’s blood that can be detected via a simple blood test – A liquid Biopsy.

Specifically, when a cancer is present in the body it is releasing a small amount of DNA into the blood that is unique to the tumour. The DNA that is free in the blood can possibly act as a partial fingerprint and allow identification of the breast tumour itself. Part of the work Dr. Green has been performing has resulted in the detection of the tumour’s DNA in the blood.

The tumour DNA can be monitored to see if it is reducing and ultimately being removed form the blood as a patient undergoes their treatment. Similarly during the follow up period a blood test can allow the research team to look for tumour DNA in the blood, which is returning, and signify that this patient is failing treatment.

This research is still in its infancy and a large quantity of work is still required until the possibility of ‘liquid biopsies’ becomes a reality. As steps are made and more information comes to light during the project more information will be made available.

If you would like to know more details about the research please contact Dr. Green’s rooms. Similarly if you wish to be involved in donating to the research team at the UQCCR Breast Bank where this research is being conducted please either contact Dr. Green or the UQCCR breast Bank manager (Prof Sunil Lakhani lab) on (07) 33466052.

 

Key-Hole Adrenal Surgery: The new approach

Bruce Abel - Wednesday, October 01, 2014

Traditionally adrenal surgery has been performed via a keyhole approach through the front of your abdomen. Dr Green is now routinely performing what is referred to as a ‘Retroperitoneal laparoscopic approach’ this is still a keyhole approach that removes the adrenal through your back.

There are a number of benefits to this type of adrenal surgery. The most beneficial improvement is a faster recovery time. Patients are usually up and about the same evening after the surgery and nearly all are ready to go home the next day. This results in a faster return to normal activities and less time away from work.

In the previous older approach from the front of your abdomen not all patients where suitable for a keyhole operation. If you have had previous abdominal surgery the keyhole approach is often not suitable or possible and a large cut was needed. This results in a prolonged hospital stay and lengthy painful recovery. The approach through the back that is performed by Dr Green can still be performed even if you have had previous abdominal surgery. Therefore, people who may not be offered keyhole surgery if having a front approach will now be suitable for a keyhole approach.

Secondly, many people are now overweight and carrying a few extra kilos than is ideal. The increased fat often made the anterior keyhole approach difficult and challenging. With the back approach abdominal fat does not get in the way and does not make the operation significantly more difficult. The posterior approach will result in less patients needing conversion to an open procedure due to their body fat and thus avoiding a large cut to complete their surgery.

Thirdly, via the back approach the instruments used to remove the adrenal gland do not have to pass in and out next to bowel. Therefore, there is a significantly reduced potential for injury to the abdominal organs making the back approach a potentially safer operation.

The back approach has been routinely performed in many large centres in the USA with excellent results confirming a faster recovery, lower conversion to open surgery with large incisions and low complication rates.
