Periodic Reporting for period 1 - IMAGINE (Widefield Raman imaging probe for intraoperative margin assessment of cancers)
Berichtszeitraum: 2016-04-01 bis 2018-03-31
The high recurrence rate and ongoing invasive monitoring requirement are the key contributors to the economic burden of cancer. With early detection and surgical intervention, the relapse and follow-up procedures would be greatly reduced, which in turn would have massive impact in terms of public health cost savings. Improved diagnosis would facilitate earlier and more efficient onset of treatment, and therefore the recurrence and follow-up procedures would be reduced, which in turn drastically reduces public health costs. Equally important, prognosis and patient quality of life improves drastically
Raman spectroscopy is a unique label-free optical technique based on inelastic light scattering that offers tissue ""optical biopsy"" at the molecular level. The objective of “Widefield Raman imaging probe for intraoperative margin assessment of cancers”, abbreviated “IMAGINE”, was to develop a platform that can be used for intraoperative cancer margin assessment. I aimed to use this type of widefield imaging to increase the targeting selectivity and enhance the diagnostic efficacy for identifying tumour cells. A key part of the objective was transfer of knowledge between The Experienced Researcher and the Stevens Group.

With the support of this MSCA-IF fellowship I was also able to broaden my research on tissue engineering and gain fundamental new understanding of photon propagation in tissues. I have successfully developed a series of engineered constructs and measured their optical properties. By using a combination of diffusion theory and Monte Carlo simulations, we were able, for the first time, to correlate the depth profile from different layers in tissue.
I have disseminated the results from this MSCA Fellowship by delivering several seminars in different universities including Kings College London, University of Southern Denmark and Sheffield University. This gave me opportunities to establish new contacts with leading scientists in the field of tissue engineering, materials science and photonics. Besides, I presented my research the largest biophotonics conference (SPIE Photonic West 2017) attracting more than 10.000 scientists. The scientific output of this Marie Curie Fellowship was 5 publications and one manuscript is in preparation based on the results of tissue optical properties and Monte Carlo modelling of photon transportation in tissue.
This research can potentially have significant socio-economic impact. The average lifetime costs for colon cancer is estimated at over ~40.000 € per patient. The potential socioeconomic impact of providing high accuracy minimally-invasive in vivo cancer margin delineation is very high. With accurate tumour delineation, the relapse and follow-up procedures would be greatly reduced, which in turn would have impact in terms of public health cost savings. Improved margin delineation would facilitate more efficient eradication, and therefore the recurrence and follow-up procedures would be reduced, which in turn drastically reduces public health costs.
