Abstract

Objective: The aim of this retrospective study is to evaluate the treatment outcomes in patients with toxic nodular goiter (TNG) that received radioiodine treatment (RAIT) and to determine the influence of age, gender, nodule size, I-131 dose, underlying etiology and antithyroid drugs on the outcomes of RAIT. Methods: Two hundred thirty three patients (mean 64±10 years old) with TNG that received RAIT were included in the study. Treatment success was analyzed according to demographic (age and gender) and clinical data (thyroid function tests before and after RAIT, thyroid sonography and scintigraphy, I-131 dose, antithyroid drugs). A fixed dose of 555 MBq was administered to patients with nodules smaller than 2 cm in diameter and of 740 MBq to patients with nodules larger than 2 cm. Hyperthyroidism treatment success was defined as achieving hypothyroidism or euthyroidism six months after RAIT. Results: In our study, the cure rate was 93.9% six months after RAIT. Hypothyroidism was observed in 74 (31.7%) patients, and euthyroidism was achieved in 145 (62.2%) patients while 14 (6%) patients remained in hyperthyroid state. Age and gender did not affect treatment outcomes. No correlation was found between underlying etiology or antithyroid drugs and therapeutic effectiveness. The effectiveness of RAIT was better in patients with nodules smaller than 2 cm. Conclusion: We observed that high cure rates were obtained in patients with TNG with 555 MBq and 740 MBq doses of I-131. While nodule diameter and RAI dose are important factors for treatment efficacy; age, gender, underlying etiology and antithyroid drugs do not affect the outcome of RAIT.

Özet

Amaç: Bu retrospektif çalışmada amaç, radyoaktif iyot tedavisi (RAIT) alan toksik nodüler guatr (TNG) hastalarında tedavi sonuçlarını değerlendirerek hasta yaşı, cinsiyet, nodül çapı, kullanılan I-131 dozu, altta yatan etiyoloji ve antitiroid ilaç kullanımı gibi faktörlerin tedavi sonuçları üzerine etkisini değerlendirmektir. Yöntem: TNG tanısıyla RAIT alan 233 hasta (64±10 yaş) çalışmaya dahil edildi. Hastalara ait demografik (yaş ve cinsiyet) ve klinik veriler (tedavi öncesi ve sonrası tiroid fonksiyon testleri, tiroid sintigrafisi ve ultrasonografi sonuçları, I-131 dozu ve antitiroid ilaç kullanımı) değerlendirildi. Nodül çapı 2 cm’den küçük olan hastalara 555 MBq ve nodül çapı 2 cm’den büyük olanlara 740 MBq olacak şekilde sabit doz RAIT verildi. Altıncı ayda hipotiroidi ve ötiroidi gelişen hastalar kür olarak kabul edildi. Bulgular: Çalışmamızda RAIT verildikten sonra altıncı ayda kür oranı %93,9 idi ve hastaların 74’ünde (%31,7) hipotiroidi, 145’inde (%62,2) ötiroidi ve 14’ünde (%6) hipertiroidi olduğu görüldü. Yaş ve cinsiyetin tedavi etkinliğini değiştirmediği görüldü. Altta yatan etiyoloji ve antitiroid kullanımı ile tedavi etkinliği arasında anlamlı bir ilişki saptanmadı. Nodül çapı 2 cm’den küçük olan hastalarda RAIT’in daha başarılı olduğu görüldü. Sonuç: TNG hastalarında 555 MBq ve 740 MBq I-131 dozları ile yüksek kür oranları sağladık. Nodül çapı ve I-131 dozu tedavi etkinliği için önemli faktörler iken yaş, cinsiyet, altta yatan etiyoloji ve antitiroid ilaç kullanımı RAIT sonuçlarında etkili olmamaktadır.
