Die Klinik der Kopfspeicheldr�sentumoren

Abstract

This paper reports on epithelial tumours arising primarily in the major and minor salivary glands. The purpose of this presentation is to summarize our experience of salivary gland tumours on the basis of a material comprising of approximately 3000 salivary gland tumours as well as a review of the literature to date. The tumours are classified according to the classification recommended by WHO 1972. The incidence, location, symptomatology, grade of malignancy and treatment of the different tumour types in this classification are reviewed. Diagnostic procedures are discussed and a scheme for surgical treatment and radiotherapy of the different types of salivary gland tumours is proposed.

Langzeitbeobachtungen von Patienten mit Mukoepidermoidtumoren im Kopf-Hals-Bereich

“…In den kleinen Speicheldrüsen kommen Mu koepidermoidtumoren 2-bis 3mal häufiger vor als in den grossen Speicheldrüsen [2], Histologisch ist eine Unterscheidung in hochdifferen zierte Formen «low grade type of malignancy» und nied rigdifferenzierte «high grade type of malignancy» vorge schlagen worden [3] Betrachtet man nun die an unserer Klinik in den letz ten 25 Jahren geübten therapeutischen Konzepte zur Be handlung niedrigdifferenzierter Mukoepidermoidtumo ren der Glandula parotis (n = 12), so fällt auf, dass unab hängig von der Radikalität des gewählten Therapiever fahrens keine Verbesserung der Prognose erreicht werden konnte. Somit verspricht auch ein ultraradikales Konzept …”

Adenoid Cystic Carcinoma of the Head and Neck

“…4, 5). It is, however, more accurate to speak of the predominance of one type or the other (9). The cribriform tumour has a more favourable prognosis than the solid carcinoma (9,12,13).…”

“…It is, however, more accurate to speak of the predominance of one type or the other (9). The cribriform tumour has a more favourable prognosis than the solid carcinoma (9,12,13). From the cribriform tumour, Perzin et al (19) separated an even more differentiated form of adenoid cystic carcinoma, the tubular carcinoma ( fig.…”

“…Solid tumours apparently are especially radiosensitive (3). However, the sensitivity of adenoid cystic carcinoma to irradiation is controversial (9,15).…”

“…It occurs more frequently in major and minor salivary glands (4%) where it represents 24% of palatal tumours, 15% of submandibular tumours and 2% of parotid tumours (9). This tumour was first described as 'cylindroma' by Billroth (2) in 1859.…”
