[Quantitative study on tongue color in primary liver cancer patients by analysis system for comprehensive information of tongue diagnosis].
OBJECTIVE
To explore the characteristics of tongue color in patients with primary liver cancer (PLC).


METHODS
Tongue color and its RGB value were analyzed quantitatively for PLC patients in different clinical periods and other cancer patients by analysis system for comprehensive information of tongue diagnosis.


RESULTS
The rate of blue and purple tongue was higher (P<0.05) and all the values of RGB were lower (P<0.01) in PLC patients compared with other cancer patients. In different clinical periods, the rate of blue and purple tongue in stage III was the highest (P<0.05).


CONCLUSIONS
The blue and purple tongue is one of the most important tongue characteristics of PLC patients.
