HR
MAS MR metabolic profiling was performed in paired samples from locally
advanced breast cancer patients obtained pre (n=19) and post (n=19)
doxorubicine treatment. PLSDA analysis
of HR MAS spectra showed classification between patients with long time
survival (≥5 years), and patients who died of cancer recurrence within
5 years. Our results suggest distinct metabolic profiles of these two patient
groups. High tCho, most significant GPC, levels before treatment correlated
to long time survival, while high glycine and lactate levels were associated
with poorer outcome.
