Classification of Precancerous Lesions of Gastric Cancerin TCM Syndrome Types

Objective:To study the current situation and structure of precancerous lesions of gastric cancer(PLGC),and to provide references for PLGC′s clinical syndrome differentiation and establishment of the primary treatment.Methods:The retrospective cohort research was used to investigate and analyze the clinical data of 110 cases diagnosed with PLGC in our hospital.Through gastroscopy,pathological diagnosis,and TCM syndrome analysis,the classification structure of PLGC syndrome is summarized,and the relationship between the syndrome composition and gastric mucosal atrophy,intestinal metaplasia,and low-grade intraepithelial neoplasia is analyzed.Results:Belching,abdominal distension,gastric pain or burning or tingling,bitter mouth,dry mouth are the most common symptoms of most patients with PLGC.In descending order of composition ratio,the common syndrome types of PLGC are Spleen-Stomach Deficiency syndrome(24.55%),Spleen-Stomach Dampness-Heat syndrome(22.73%),Liver and Stomach Qi stagnation syndrome(20.00%),Stomach collateral Blood stasis syndrome(12.73%)and Stomach Yin Deficiency syndrome(8.18%).Among them,gastric mucosal atrophy is more common in Spleen-Stomach Deficiency syndrome(32.14%),intestinal metaplasia is more common in Liver and Stomach Qi stagnation syndrome(28.95%),and low-grade intraepithelial neoplasia is more common in Stomach collateral Blood stasis syndrome(50.00%).Conclusion:The five syndromes of Spleen-Stomach Deficiency syndrome,Spleen-Stomach Dampness-Heat syndrome,Liver and Stomach Qi stagnation syndrome,Stomach collateral Blood stasis syndrome and Stomach Yin Deficiency syndrome are the main clinical syndromes of PLGC.Different syndromes are associated with different pathological stages such as atrophy,intestinal metaplasia,and low-grade intraepithelial neoplasia.With the pathological progression of atrophy-intestinal metaplasia-low-grade intraepithelial neoplasia,the pathogenesis changes in trend of Spleen-Stomach Deficiency-Liver and Stomach Qi stagnation-Stomach collateral Blood stasis.
