Levels of S1P and sphingosine in breast cancer tissues compared with the lymphatic invasion (ly) and pathological regional lymph nodes (pN) status. The levels of S1P and sphingosine were determined in the patients with ly absent or ly present (A and B), and in the patients with pN0 or pN1-3 (C and D). Mean values are shown by horizontal lines. The statistical analysis was done by the Mann-Whitney U test.
