Study on traditional Chinese medicine syndromes of primary liver cancer based on factor analysis and cluster analysis
To analyze the characteristics and distribution patterns of traditional Chinese medicine (TCM) syndromes in patients with primary liver cancer (PLC).
Methods
2
A prospective research method was used to collect information on the TCM four diagnoses and symptoms of 381 PLC patients. Factor analysis was conducted on the eligible entries of TCM four diagnoses and symptoms using SPSS 25.0 statistical software, employing principal component analysis, and common factors were extracted, and cluster analysis was carried out on the entries of information to interpret the symptomatic features corresponding to the common factors and to explore the characteristics and distribution patterns of PLC symptoms.
Results
2
Seven common factors with eigenvalues greater than 1 were identified. Based on TCM theory and clinical practice, the main affected organs in PLC were the liver, spleen, and kidneys, presenting a mixed pattern of deficiency and excess. The pathological factors involved were blood stasis, qi stagnation, damp-heat, qi deficiency, yin deficiency, yang deficiency, and water retention. The most common syndrome was qi stagnation and blood stasis (24.147%), followed by damp-heat toxin accumulation (18.373%), spleen and stomach deficiency (12.861%), liver and kidney yin deficiency (12.336%), liver qi stagnation (11.549%), spleen and kidney yang deficiency (10.499%), and qi-yin dual deficiency (10.236%). Qi stagnation and blood stasis syndrome, and damp-heat toxin accumulation syndrome were more common in PLC patients with stages Ⅰ and Ⅱ, while liver and kidney yin deficiency syndrome, qi-yin dual deficiency syndrome, and spleen and kidney yang deficiency syndrome were more common in stage Ⅲ patients.
Conclusions
2
It is feasible to analyze syndromes of PLC using factor and cluster analyses. The main TCM syndromes for PLC include qi stagnation and blood stasis, damp-heat toxin accumulation, liver and kidney yin deficiency, and liver qi stagnation. Different clinical stages of PLC patients have distinct TCM syndrome characteristics. These findings could provide a foundation for further clinical research on TCM syndromes of PLC.
