Reduced expression of p27/Kip1 is associated with the development of pulmonary adenocarcinoma

Relationship between gastric carcinoma traditional Chinese medicine classifications of syndrome and tumor proliferation

AIM: To study the relationship between gastric carcinoma traditional Chinese medicine (TCM) classifications of syndrome and tumor proliferation.

METHODS: Ninety-one patients with gastric carcinoma were assigned into 6 groups according to TCM classification of syndrome criteria before operation. Specimens prepared from operation were detected for Ki67 and Cyclin E protein expression by EnVision method of immunohistochemistry.

RESULTS: The positive rates of Ki67 and Cyclin E expression were 98.90% (90/91) and 72.53% (66/91), respectively, in gastric carcinoma. The expression of Cyclin E protein was correlated with the histological types (P = 0.039 4) and distant metastasis (P= 0.009 6). There was significantly positive relationship between Cyclin E protein expression and distant metastasis in female patients (P = 0.019 3). The expression of Ki67 protein had significant correlations with gastric carcinoma TCM classifications of syndromes (P = 0.037 7), but the expression of Cyclin E protein did not (P = 0.125 4). The expression of Ki67 in the syndrome of "Incoordination between the Liver and Stomach" was significantly higher than that of "Phlegm-damp Coagulation" (P < 0.05) or "Deficiency of both Qi and Blood" (P < 0.01), and it was more significant in the syndrome of "Stomach-heat and Deficiency of Stomach-yin" than that of "Phlegm-damp Coagulation" (P < 0.05).

CONCLUSION: Cyclin E can be used as an important marker in the judgment of gastric carcinoma prognosis. Tumor proliferation is partly different among different gastric carcinoma TCM classifications of syndromes, with which Ki67 protein expression is correlated.
