To use the Patient Reported Information Multidimensional Exploration (PRIME) framework, a novel ensemble of machine learning and deep learning algorithms, to extract, analyse and correlate self-reported information from online support group discussions (OCSG) by patients (and partners of patients) with low-intermediate risk PCa undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT) and active surveillance (AS), and investigate its efficacy in determining Quality of life (QOL) and emotion measures.
