Tissue metabolomics study reveals diagnostic and prognostic biomarkers in prostate cancer patients, indicating potential tools for predicting biochemical recurrence.

Key Points

To evaluate the diagnostic and prognostic utility of specific tissue metabolites for identifying malignancy and predicting biochemical recurrence after radical prostatectomy.
Analyzed matched malignant and nonmalignant prostate tissue samples from 95 prostate cancer patients using combined gas chromatography and liquid chromatography-mass spectrometry.
Profiled nine candidate metabolites and evaluated their associations with clinicopathological parameters, including Gleason score, tumor stage, preoperative PSA, and biochemical recurrence (defined as PSA > 0.2 ng/mL).
Seven metabolites were elevated in malignant tissue compared with nonmalignant tissue, while gluconic acid and maltotriose were reduced; tricosanoic acid showed the highest diagnostic discrimination (area under the curve = 0.86).
Univariate analyses linked aminoadipic acid, gluconic acid, and maltotriose to biochemical tumor recurrence, and multivariate Cox regression confirmed aminoadipic acid as an independent predictor of recurrence alongside tumor stage and Gleason score.
