There are a lot of clinical practices of Chinese medicine treating precancerous lesions of gastric cancer（ PLGC）

but the lacks of therapeutic evaluation methods seriously restrict Chinese medicine advantages and reliability of therapeutic effect. Based on summarizing the research status of Chinese medicine treating PLGC

the authors hold that the existed problems of therapeutic evaluation methods of Chinese medicine treating PLGC mainly include the following aspects

adopting composite evaluation indexes and leading to confused effect; lack of united histopathological indexes evaluation methods which influence comparability of the results; evaluating lesions under gastroscopic observation with strong subjectivity and influenced by many factors and conditions; lacks of methodological basis when evaluating symptoms and Chinese medicine syndromes; lack of evaluation of quality of life

etc. Aiming at these problems

the authors propose combinated evaluation of disease therapeutic effect and Chinese medicine syndrome effect and establish comprehensive evaluation system of histopathological indexes as core

combined with gastroscopic indexes

patients’ symptoms

quality of life and other indexes.
