Conclusion

Plasma sarcosine concentrations measured by GC-MS analysis had "good" and "very good" classification performance for distinguishing PIN and PCa, respectively, relative to noncancerous patients, suggesting that it may be a promising complementary biomarker when used together with PSA. Further research is needed to better assess if plasma sarcosine differentiates patients diagnosed with PCa with different Gleason scores.
