[Implications of the reclassification study of tumors of the salivary glands of the head]. / Konsequenzen aus Studien zur Reklassifizierung von Geschwülsten der Kopfspeicheldrüsen.

A reclassification of 272 tumors of the salivary glands of the head resulted in a high proportion of new allocations, particularly among adenocarcinomas, adenoid cystic carcinomas, and pleomorphic adenomas, sometimes even involving a different assessment of the tumors' benign or malignant character. The implications for clinical practice and for prognostic studies are discussed.

[Monocentric retrospective study on the prognosis of adenoid cystic carcinoma]. / Monozentrische retrospektive Studie zur Prognose des adenoidzystischen Karzinoms.

Studies on 26 patients confirm the relevance of the factors tumour size and histological subtype for the prognosis of adenoid cystic carcinoma. For high risk tumours (tumour size over 3 cm, solid or tubular subtype) a postoperative adjuvant radiologic therapy is recommendable. The rate of wrong diagnoses found by reclassification is surprisingly high.
