Abstract:

BACKGROUND: The CD133 expression in non-small cell lung cancer shows some changes, which is definitely related to the occurrence and development of diseases.
OBJECTIVE: To investigate the expression of CD133 in non-small cell lung cancer, and to analyze its relationship with clinical pathological factors and prognosis.
METHODS: Non-small cell lung cancer tissue specimens from 135 cases were collected, and normal lung tissue specimens from 60 cases were set as normal control group. Immunohistochemical staining was used to detect CD133 expression in two groups, and the relationship between the expression of CD133 protein and the clinical pathological factors was analyzed.
RESULTS AND CONCLUSION: (1) The positive expression of CD133 protein in the non-small cell lung cancer group was significantly higher than that in the normal control group (P < 0.05). (2) CD133 protein expression had no association with age, gender, tumor size, tumor location, histological type (P > 0.05), and CD133 protein expression was significantly increased with the differentiation of non-small cell lung cancer (P < 0.05). The positive expression rate of CD133 protein was significantly different between different clinical stages and lymph node metastasis (P < 0.05). (3) CD133 and TNM staging were independent prognostic factors for non-small cell lung cancer (P < 0.05), and the median survival time was significantly shorter in the positive group than in the  negative group (P < 0.05). The results indicate that CD133 is involved in the occurrence, development, infiltration and metastasis of non-small cell lung cancer, and it hasimportant clinical significance for the disease progression and prognosis.
