Breakthrough discovery by UCD Centre for Precision Surgery, surgeons at Mater Hospital
re-affirms that 21st century surgery is digital
(Mon 31st May 2021) A study published today in Nature Scientific Reports (see Publication here), shows how dynamic visual appearances obtainable during surgery, using innovative digital processing, can provide more comprehensive information on the extent and type of malignant tissue, especially in colon-rectal cancer, to surgeons in moments. This discovery has the potential to exploit already established microscopic principles in medical oncology and histopathology but principles which have never before, been revealed and understood in real-time, in living tissue.
Previously, surgeons had to wait for considerable time frames to have formal characterisation of tissue types performed by laboratories or to understand responsiveness to medical therapies by interval radiological imaging. In contrast, this method allows a surgeon to ‘see’ the cancerous tissue not just by its gross appearance but by its behaviour and distinguish it clearly from nearby normal tissue. This discovery also has the potential to open up a new field for diagnosis and curative treatment and to radically improve health outcomes.
In summary the ‘Digital dynamic discrimination of primary colorectal cancer using systemic indocyanine green with near-infrared endoscopy’ study as published in Nature Scientific Reports shows that;
Speaking about this discovery, Ronan Cahill, Professor of Surgery at UCD and the Mater Misericordiae University Hospital (MMUH) and Nature Scientific Report paper author said ‘Dynamic digital discrimination of cancer right at the time of intervention means the surgical team can better perfect the right intervention to the individual patient first time. The tools we are developing are straightforward to deploy and use software to allow users easily interpret the findings without having to develop further specialist knowledge. If cancer can be fully detected, it’s much more likely to be cured in one single operation or have combination therapies better sequenced and so the risk to the patient of recurrence and complications are markedly reduced.”
“Traditional research means insights developed in academic labs subsequently need considerable additional development to make ready for in-human trialling, often these mean completely new technology and care processes have to be created and many discoveries fail to make any useful contribution despite early excitement and a lot of work and investment. By working within a leading clinical care centre and building the research entirely around patients and their care by assembling a team of interdisciplinary experts, we have been able to safely accelerate and apply the research in the clinic meaning current cancer care needs are perfectly matched. By collaborating early and closely with excellent industry partners, we minimise the many uncertainties that beset the path to patient usefulness” continued Prof Cahill.
Also speaking about this discovery, Jeffrey Dalli, General Surgeon, Surgical Research Fellow at UCD Centre for Precision Surgery and Lead Author of today’s paper in Nature Scientific Reports said ‘Colon and rectal cancers are common, being the second most common major cancer type in men and women and they are increasing in incidence especially among younger people. Alongside the projected increased incidence of early-stage colorectal cancer which is already curable by surgery, advances in treatment mean more patients with advanced disease are increasingly also able to be cured by including surgery again after initial chemotherapy or radiotherapy. Together, these facts have expediated interest in perfecting methods for surgeons to define exactly the nature and extent of malignant deposits at the time of intervention so that both the maximum amount of disease can be removed (to maximise cure) with a minimum of normal surrounding tissue (to minimise functional incapacity). The technology will help surgeons better discriminate during operations exactly what is best for each individual patient.’
