Role of Radiotherapy in Parotid Pleomorphic Adenoma: Two Case Reports and a Review of the Literature

Öz

Pleomorphic adenoma is the most common benign salivary gland neoplasm (%75-80). It is found mostly in the parotid gland in middle-aged women. The optimal treatment is superficial or total parotidectomy with facial nerve preservation, which results in local control rates of 95% or higher. Radiotherapy (RT) is indicated for ositive margins, unresectable tumours, and multifocal recurrences after prior resection. Local control rates after RT for microscopic and gross residual tumour are approximately 80% to 85% and 40% to 60%, respectively. In this article, we share our experience of 2 cases of recurrent pleomorphic adenoma.

Pleomorfik adenomlar tükrük bezlerinin en sık görülen iyi huylu neoplazmlarıdır . Genelde orta yaşlı kadınlarda ve parotis bezinde bulunur. Optimal tedavi şekli fasial siniri koruyarak yapılan superfisyal veya total parotidektomidir. Cerrahi ile %95 ve üzerinde başarı vardır. Radyoterapi(RT) pozitif cerrahi sınırda, unrezektabl hastalıkta ve cerrahi sonrası multifokal nüksde kullanılır. RT sonrası lokal kontrol mikroskopik hastalıkta %80-85 ve gros rezidüel hastalıkta %40-60 arasındadır. Biz de bu makalede cerrahi sonrası nüks eden 2 olguyu adjuvan RT deneyimimizi paylaştık
