Abstract

Objectives: This study aims to evaluate our single center experience in patients with a salivary gland tumor receiving postoperative radiation therapy (RT). Patients and Methods: Between January 1996 and December 2011, the records of 34 salivary gland tumor patients who were operated and referred to our clinic for adjuvant RT were retrospectively analyzed. Radiation therapy was applied to the primary tumor and lymphatics at a median dose of 60 Gy (54 to 60 Gy) with 1.8-2 Gy/fraction. Results: The median follow-up was 38 months (range, 3 to 204 months). The most common site of involvement was the parotid gland in 21 patients (62%), followed by the submandibular gland in 11 patients (%24) and minor salivary gland in two patients (9%). Five-year overall survival (OS) was 49% (range, 3 to 206 months) and disease free survival (DFS) was 61% (range, 1 to 173 months). Six patients had local or regional recurrences (18%), while 13 patients (38%) had distant metastasis. A tumor size larger than 4 cm, over six weeks referral time to RT, and existence of metastatic lymph node were found to be poor prognostic factors for OS (p=0.023, p=0.039, respectively), and DFS (p=0.046). While extracapsular involvement significantly reduced the DFS and OS (p=0.022, p=0.050, respectively), overall RT time affected DFS alone (p=0.046). Conclusion: We recommend adjuvant RT in high-risk patients operated due to a salivary gland tumor.

Özet

Amaç: Bu çalışmada ameliyat sonrası radyoterapi (RT) alan tükürük bezi tümörlü hastalarda tek merkez deneyimimiz değerlendirildi. Hastalar ve Yöntemler: Ocak 1996 - Aralık 2011 tarihleri arasında ameliyat edilen ve adjuvan RT tedavisi için kliniğimize sevk edilen 34 tükürük bezi tümörlü hastanın dosyaları retrospektif olarak incelendi. Primer tümör veya lenfatiklerine 1.8-2 Gy/fraksiyonda medyan 60 Gy (54-70 Gy) dozunda RT uygulandı. Bulgular: Medyan izlem süresi 38 aydı (dağılım, 3-204 ay). Hastalık en sık 21 hastada (%62) parotis bezinde, bunu takiben 11 hastada submandibüler bezde (%24) ve iki hastada da minör tükürük bezinde (%9) gözlendi. Beş yıllık genel sağkalım (GSK) %49 (dağılım, 3-206 ay) ve hastalıksız sağkalım (HSK) %61 (dağılım, 1-173 ay) idi. Altı hastada (%18) lokal veya bölgesel nüks gelişirken 13 hastada (%38) uzak organ metastazı gelişti. Tümör çapının 4 cmden büyük olması ve RTye altı haftadan geç başlanması GSK için (sırasıyla, p=0.023, p=0.039), metastatik lenf nodu varlığı ise HSK için kötü prog- nostik faktörlerdi (p=0.046). Ekstrakapsüler tutulum varlığı HSK ve GSKyi anlamlı düzeyde kısaltırken (sırasıyla, p=0.022, p=0.050), genel RT süresinin yalnızca HSKyi etkilediği gözlendi (p=0.046). Sonuç: Tükürük bezi tümörü nedeniyle ameliyat edilen yüksek riskli hastalarda adjuvan RTyi önermekteyiz.
