摘要: Aims: To study the association between morphological changes of bronchial epithelium and its angiogenic status evaluated by microvessel count (MVC), in order to gain a better understanding carcinogenesis. Also, correlate MVC with epidermal growth factor receptor (EGFR) expression. Methods results: Eighty-three biopsy specimens were assessed for MVC: four normal epithelia, 23 hyperplasias, 26 metaplasias, two mild dysplasias, five moderate nine severe three carcinomas situ, six early invasive squamous cell (EIC) cases micropapillomatosis. We observed statistically significant difference terms EIC all other subgroups micropapillomatosis subgroups. There was also EIC. did not observe any mucosa, dysplasias or carcinoma situ. EGFR expression higher dysplasia, situ EIC, whereas it very low A profile vs. MVC. increased an increase occurred only EIC. Conclusion: During carcinogenesis, except micropapillomatosis, appears be prerequisite neoangiogenesis
