MethodsA total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. ResultsThe study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). ConclusionsEpidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.eninfo:eu-repo/semantics/openAccessAdenoid cystic carcinomaDistant metastasesPrognostic-factorsRisk-factorsSurvivalTumorsHeadNeckRecurrenceOutcomesHistopathologyIncidenceMajor salivary glandMinor salivary glandSalivary gland cancersOtorhinolaryngologySurgeryArticle0009774590000011643165345710.1002/hed.27376
