INTRODUCTION: The salivary duct carcinoma (sdc) represents a rare variant of the group of adeno-carcinomas of the salivary glands. Histopathologically, it is marked by solid and cribriform cell nests with central necrosis, displaying distinct similarity with the ductal carcinoma of the breast, where prognosis can be correlated with Her-2 gene-amplification. Based on this histopathological similarity, the prognostic value of Her-2 gene amplification in SDC was examined in the presented pilot-study.
PATIENTS AND METHODS: Four own patients with different clinical courses were examined in regard to their histopathological features, Her-2 gene-amplification and proliferation (Ki67).
RESULTS: Three of the four patients died tumor related 2.4, 5.5 and 8.2 years after initial diagnosis. The remaining patient died tumor-free 6 year after diagnosis (myocardial infarct). The two patients with an early recurrent disease and distant metastasis showed a high Her-2 expression and proliferation (Ki67), compared to the other two patients.
CONCLUSION: In the presented pilot-study a distinct correlation between Her2-gene-amplification, proliferation (Ki67) and clinical course could be observed. Additional analysis to evaluate this aspect seems rectified, especially under recognition of therapy decisions.
