In the search for improved treatment and care for breast cancer patients, understanding breast cancer biology is important. For molecular mechanisms studied in vitro to be translated to clinical use, metabolic information should relate to clinically relevant parameters. Breast cancer tissue metabolic concentrations have been quantified and directly correlated to prognostic factors and patient outcome. Biopsies from diseased patients have higher concentrations of choline than samples from patients with good and poor prognosis. Trend towards significance were found for lower GPC in the good prognosis group and higher PC in diseased group compared to poor prognosis group. Significant differences between groups of samples were also found for ratios of GPC/Gly and PC/GPC.
