摘要

Objective: Adenoid cystic carcinoma (ACC) of the tracheobronchial tree is quite uncommon. The clinicopathologic analysis and the therapeutic outcomes of tracheobronchial ACC have been reported earlier. However, their biological behavior should differ from other tracheal neoplasms. Thus, DNA flow cytometric analysis and biomarkers of p53, HER-2/neu and COX-2 for tracheobronchial ACC were investigated in order to evaluate their clinicopathological significance. Methods: Between 1985 and 1999, nine patients with tracheobronchial ACC were included for the study. All the patients had pathologically confirmed ACC. Five were male and four were female. Eight patients underwent surgical resections. Seven paraffin embedded tumors from six patients were available for DNA flow cytomeric analysis and immunohistochemical staining of p53, HER-2/neu and COX-2. Results: Histologically, nine pathologic specimens from eight surgical patients (including one patient received operation twice) showed one grade I, five grade II and three grade III. The mitotic activity, lymphatic invasion and vascular invasion were more frequent in advanced grading tumor. The higher grade tumors seemed to be associated with a higher synthetic phase fraction (SPF). Immunohistochemically, except for one grade II tumor showing positive expression of HER-2/neu, all the seven tumorous samples revealed negative expressions of p53, COX-2 and HER-2/neu. The patient with positive HER-2/neu tumor had distant metastases 4 years after surgery. Conclusions: Complete surgical resection may provide best survival for tracheobronchial ACC. The DNA ploidy and SPF may correlate with tumor grading or metastasis. The overexpressions of HER-2/neu, p53 and COX-2 may impact the prognosis in patients with stage I non-small cell lung cancer, but did not express difference in our patients.
