Description
Despite the advancement in the management of prostate cancer in recent years, treatment
strategies are only efficient against localized disease while managing metastatic cancer
remains a challenge. As a result, the global burden of the disease has remained significant.
Efficient and personalized management of the disease before metastasis is therefore of
prime importance. In this study, we developed a classifier to predict the response of
prostate cancer patients to treatment leveraging on multi-omics datasets provided by The
Cancer Genome Atlas (TCGA). Our investigation using ten machine learning algorithms
reveals that tree-based algorithms had better predictive performance than probabilistic
models such as Naive Bayes and kernel-based methods such as Support Vector Machines.
We also investigated the performance of all possible omics combinations. Our results show
that there is an overall increase in performance when multiple omics datasets are used in
contrast to single omics strategies. We have predicted for the first time, possible androgen
deprivation treatment response outcomes for 68 prostate cancer patients with missing
phenotype values in the TCGA dataset.
