Özet
Amaç: Diferansiye tiroid kanseri tanısı almış ve I-131 ablasyon tedavisi verilmiş hastalarda, hastaya ve hastalığa ait faktörlerin ablasyon başarısı üzerinde etkilerinin olup olmadığının araştırılmasıdır. Gereç ve Yöntemler: Temmuz 2007- Eylül 2009 tarihleri arasında Dokuz Eylül Üniversitesi Tıp Fakültesi Nükleer Tıp ABD Radyonüklid Tedavi Polikliniği’ne başvuran, diferansiye tiroid karsinomu tanısı almış, total/totale yakın tiroidektomi yapılmış ve I-131 ablasyon tedavisi verilmesi için refere edilmiş hastalar ve çalışma süresi içinde en az 6. ay kontrollerine gelen tüm hastalar değerlendirmeye alındı. Hasta dosyaları retrospektif olarak tarandı. Hastalara ait yaş, cinsiyet, tümör tipi, tümör subtipi, tümör kapsül varlığı ve invazyonu, tümör boyutu, tümör sayısı, tümör lokalizasyonu, tiroid kapsül ve lenf/damar invazyonu, metastatik lenf nodu varlığı, operasyon şekli, preablasyon Tiroglobulin (Tg), Anti-Tiroglobulin (ATG), Tiroid Stimule Edici Hormon (TSH), metastaz tarama için görüntülemeler (tiroid ve kemik sintigrafisi, boyun ve abdomen ultrasonografi, toraks ve beyin bilgisayarlı tomografisi), verilen doz, post ablasyon I- 131 tüm vücut taraması (TVT), 6. ayda diagnostik I-131 TVT, boyun USG, Tg, ATG sonuçları değerlendirildi. Tiroid lojunda rezidü saptanmayan hastalar ‘ablasyon başarılı’ , rezidü saptanan hastalar ise ‘ablasyon başarısız’ olarak kabul edildi. Bulgular: Çalışmaya diferansiye tiroid karsinom tanılı 191 hasta alındı. Ablasyon başarısı %74,3 olarak hesaplandı. Hastaların 15’inde (%7,8) ablasyon öncesi metastaz saptanmıştı. Metastatik hastalarda ablasyon başarısı %66 iken metastaz negatif grupta ise %75 idi. Patolojik lenf nodu sayısı ile ablasyon başarısı arasında anlamlı bir ilişki bulunurken (p=0,025), diğer faktörler (lenf nodu sayısı, yaş, cinsiyet, tümör tipi, tümör odak sayısı, tiroid kapsül ve lenf/kan damar invazyonu vb.) ile ablasyon başarısı arasında anlamlı bir ilişki saptanmadı. Sonuç: Diferansiye tiroid kanser tanılı ve I-131 ablasyon tedavisi verilen hastalarda patolojik lenf nodu sayısı ile ablasyon başarısı arasında anlamlı bir ilişki mevcuttur. Ancak bu bulgunun örneklem büyüklüğünün küçük olması nedeniyle istatistiksel hataya bağlı da olabileceği düşünülmüştür. Bu değişken dışında diğer prognostik faktörler ile ablasyon başarısı arasında anlamlı bir ilişki bulunamamıştır. (MIRT 2012;21:103-109)
Objective: To investigate whether the factors related to the patient and the disease have any effect on the success of ablation therapy in patients with differentiated thyroid cancer who have received I-131 ablation therapy. Material and Methods: All the patients with differentiated thyroid cancer were referred for I-131 ablation therapy after thyroidectomy between July 2007 and September 2009. The patients had at least six months of follow-up. Age, gender, type of tumor, presence of capsule invasion, size of tumor, number of the tumors, localization of the tumor, invasion of thyroid capsule, lymph/vessel invasion, presence of metastatic lymph nodes, type of surgery, preablation values of thyroglobulin (Tg), AntiTg, TSH, surveys for the evaluation of metastatic disease, (thyroid and bone scintigraphy, neck and abdominal ultrasonography, chest and brain computerized tomography), administered dose, postablation I-131 whole body scan (WBS) and diagnostic I-131 WBS, neck USG, values of Tg and AntiTg at the 6th month were recorded. The presence of residual thyroid activity on the 6th month diagnostic I-131 WBS image was accepted as the criterion for ablation success. Results: 191 patients with differentiated thyroid cancer were assessed in this study. The overall success rate of the first ablation therapy was 74.3%. The success rate of the ablation therapy was 66% and 75% in metastatic group and non-metastatic group, respectively. Except the significant correlation between the number of pathologic lymph nodes and the success of ablation (p=0.025), there was no other significant correlation between the patient/disease related factors and the success of ablation therapy. Conclusion: Significant correlation between the number of the pathologic lymph nodes and the ablation therapy performance can also be due to statistical error because of the limited sample size. There was no significant correlation between other patient/disease related prognostic factors and the success of ablation therapy. (MIRT 2012;21:103-109)
