A stratification protocol is presented to identify prostate cancer patients at risk of poor outcomes using infrared hyperspectral data paired with machine learning. The approach is validated on a large cohort (n=183) with biopsy cores (n=1440), using patient age and PSA as the only additional clinical inputs. Identified outcome groups closely align with groups separated by tumour stage.","The University of Manchester Research  \nIdentification of at-risk prostate cancer patients using Fourier Transform Infrared Spectroscopy and Machine Learning  \nDOI:  \n10.1117/12.3048498  \nDocument Version  \nAccepted author manuscript  \nLink to publication record in Manchester Research Explorer  \nCitation for published version (APA):  \nFerguson, D. , Sachdeva, A. , Hart, C.

This technique can be used to assist in determining the prognosis of prostate cancer patients, aiding the treatment decision protocols employed by clinicians. We report a stratification protocol to identify at-risk prostate cancer patients with poor outcomes from a large patient study (n=183) through the usage of label-free chemical imaging (without chemical de-waxing or staining) of numerous prostate cancer biopsy cores (n=1440) paired with machine learning techniques, without consideration of additional clinical variates beyond patient age and PSA levels. Distinctly different patient outcome groups are identified using infrared hyperspectral data, closely matching patient groups separated by tumour stage.  \nKeywords: Fourier transform infrared (FT-IR) spectroscopy, mid-infrared, chemical imaging, spectral histopathology, prostate cancer, diagnostics, machine learning, patient outcome.  \n1.
