To explore the syndrome differentiation patterns of breast cancer, indentify the main four diagnostic method information of the syndrome types, and establish foundation for setting up standards for syndrome differentiation types of consolidate period in patients with breast cancer after surgeries. Methods:Questionnaires were given to 1102 patients admitted to breast department of Guangdong province Hospital of TCM from June 2009 to June 2012 who were on the consolidate period of breast cancer. Methods of category analysis and frequency normalization were used. Results:Four patterns were concluded to be clinically practical by the confirmation of experts, including spleen-kidney deficiency pattern(34.8%), kidney deficiency with blood stasis pattern(27.9%), deficiency of liver -kidney yin pattern (4.7%) and disease without syndrome pattern (32.5%). Conclusion: epidemiology investigation and statistical analysis are used to establish the syndrome differentiation patterns and indexes for consolidate period of breast cancer, which provides theoretical evidence for treating patients in this phase.
