[Correlation Study between Syndrome Types of Chinese Medicine and Molecular Subtyping of Breast Cancer in Consolidate Period].

Objective To observe the correlation between syndrome types of Chinese medicine (CM) and molecular subtyping of breast cancer in consolidation period. Methods Multivariate statistical analysis was applied in this research. Totally 612 breast cancer patients in consolidation period were as- signed to 4 syndrome types of CM [qi deficiency syndrome (22. 22% , 136/612) , Gan-qi stagnation syn- drome (21.73%, 133/612), Gan-Shen yin deficiency syndrome (20.10%, 123/612), Shen deficiency blood stasis syndrome (35. 95%, 220/612) ]. The correlation between each syndrome type and each molecular subtyping was respectively analyzed using Χ² (R x C table) test. Results Through statistical a- nalysis and expert consultation, results showed that cluster four types in consolidate period of breast cancer were compatible. Each syndrome type was correlated with each molecular subtyping in 612 breast cancer patients in consolidation period. Luminal type A was correlated with Gan-qi stagnation syndrome (P <0. 05). Luminal type B and triple negative type were correlated with qi deficiency syndrome and Gan- Shen yin deficiency syndrome (P <0. 05). But each syndrome type was not obviously correlated with dis- ease course. There was no obvious correlation between molecular subtyping and age/disease course (P >0. 05). Conclusion Luminal type A occupied the highest ratio in Gan-qi stagnation syndrome, with relatively better prognosis.
