Abstract

This proposal brings together a critical mass of scientists from the Universities of Cardiff, Lancaster, Liverpool and Manchester and clinicians from the Christie, Lancaster and Liverpool NHS Hospital Trusts with the complementary experience and expertise to advance the understanding, diagnosis and treatment of cervical, oesophageal and prostate cancers. Cervical and prostate cancer are very common and the incidence of oesophageal is rising rapidly. There are cytology, biopsy and endoscopy techniques for extracting tissue from individuals who are at risk of developing these diseases. However the analysis of tissue by the standard techniques is problematic and subjective. There is clearly a national and international need to develop more accurate diagnostics for these diseases and that is a primary aim of this proposal.
Experiments will be conducted on specimens from all three diseases using four different infrared based techniques which have complementary strengths and weaknesses: hyperspectral imaging, Raman spectroscopy, a new instrument to be developed by combining atomic force microscopy with infrared spectroscopy and a scanning near field microscope recently installed on the free electron laser on the ALICE accelerator at Daresbury. The latter instrument has recently been shown to have considerable potential for the study of oesophageal cancer yielding images which show the chemical composition with unprecedented spatial resolution (0.1 microns) while hyperspectral imaging and Raman spectroscopy have been shown by members of the team to provide high resolution spectra that provide insight into the nature of cervical and prostate cancers. The new instrument will be installed on the free electron laser at Daresbury and will yield images on the nanoscale. This combination of techniques will allow the team to probe the physical and chemical structure of these three cancers with unprecedented accuracy and this should reveal important information about their character and the chemical processes that underlie their malignant behavior. The results of the research will be of interest to the study of cancer generally particularly if it reveals feature common to all three cancers.
The infrared techniques have considerable medical potential and to differing extents are on the verge of finding practical applications. Newer terahertz techniques also have significant potential in this field and may be cheaper to implement. Unfortunately the development of cheap portable terahertz diagnositic instruments is being impeded by the weakness of existing sources of terahertz radiation. By exploiting the terahertz radiation from the ALICE accelerator, which is seven orders of magnitude more intense that conventional sources, the team will advance the design of two different terahertz instruments and assess their performance against the more developed infrared techniques in cancer diagnosis. However before any of these techniques can be used by medical professionals it is essential that their strengths and limitations of are fully understood. This is one of the objectives of the proposal and it will be realised by comparing the results of each technique in studies of specimens from the three cancers that are the primary focus of the research. This will be accompanied by developing data basis and algorithms for the automated analysis of spectral and imaging data thus removing subjectivity from the diagnostic procedure.
Finally the team will explore a new approach to monitoring the interactions between pathogens, pharmaceuticals and relevant cells or tissues at the cellular and subcellular level using the instruments deployed on the free electron laser at Daresbury together with Raman microscopy. If this is successful, it will be important in the longer term in developing new treatments for cancer and other diseases.
 
Description We have discovered that infrared spectroscopy can be used as an objective method to diagnose cancer in biopsy tissue samples. We have used a range of infrared sampling methodologies at various spatial resolutions and have seen that a basic cancer vs cancer classifier can be made at low resolution with a standard instrumentation. For more detailed analysis and sub-classification finer details are required.

As part of this project a new method of data analysis related to tissue has been developed
Exploitation Route We hope that infrared imaging will be commercialized so that it will be used routinely in the clinic.

In addition the university of Manchester has provided ~450K of funding for a high resolution optical photothermal IR microscope to continue with the high resolution tissue imaging work.

Title Quantum Cascade Laser Spectral Histopathology: Breast Cancer Diagnostics Using High Throughput Chemical Imaging 
Description Fourier transform infrared (FT-IR) microscopy, coupled with machine learning approaches, has been demonstrated to be a powerful technique for identifying abnormalities in human tissue.  The ability to objectively identify the prediseased state, and diagnose cancer with high levels of accuracy, has the potential to revolutionise current histopathological practice.  Despite recent technological advances in FT-IR microscopy, sample throughput and speed of acquisition are key barriers to clinical translation. Wide-field quantum cascade laser (QCL) infrared imaging systems with large focal plane array detectors utilising discrete frequency imaging, have demonstrated that large tissue microarrays (TMA) can be imaged in a matter of minutes.  However this ground breaking technology is still in its infancy and its applicability for routine disease diagnosis is, as yet, unproven. In light of this we report on a large study utilising a breast cancer TMA comprised of 207 different patients.  We show that by using QCL imaging with continuous spectra acquired between 912 and 1800 cm -1, we can accurately differentiate between 4 different histological classes.  We demonstrate that we can discriminate between malignant and non-malignant stroma spectra with high sensitivity (93.56%) and specificity (85.64%) for an independent test set.   Finally, we classify each core in the TMA and achieve high diagnostic accuracy on a patient basis with 100% sensitivity and 86.67% specificity.  The absence of false negatives reported here opens up the possibility of utilising high throughput chemical imaging for cancer screening, thereby reducing pathologist workload and improving patient care.
