Abstract
OBJECTIVE
Evaluation of altered urinary nucleosides before and after tumor removal of breast cancer (BCa).
DESIGN AND METHODS
Targeted metabolite profiling of 14 urinary nucleosides was conducted with both pre- and post-operative female patients with BCa (n=150, age: 46.6+/-7.7 years), and female controls (n=150, age: 46.8+/-7.7 years) by liquid chromatography-tandem mass spectrometry coupled to on-line extraction.
RESULTS
Levels of modified nucleosides (5-hydroxymethyl-2'-deoxyuridine, P<0.001; 8-hydroxy-2'-deoxyguanosine, P<0.001; 1-methyladenosine, P<0.02; N(2),N(2)-dimethylguanosine, P<0.001) were significantly higher in pre-operative patients than in both normal controls and post-operative patients.
CONCLUSIONS
This approach could be used to further understand the pathogenesis of BCa as well as to evaluate the effects of medical treatment.
