Abstract

ÖZET
Amaç: Postoperatif radyoaktif iyot (RAI) ablasyonu, diferansiye tiroid karsinomlarında (DTK) tiroidektomi sonrası tamamlayıcı
tedavi seçeneklerinden birisidir. Tiroidektomi sonrası rezidü dokunun değerlendirilmesi, postoperatif RAI
ablasyonunun etkinliği açısından önemlidir. Çalışmamızda total tiroidektomi (TT) sonrası rezidü doku tespit edilmiş
DTK’lı olgularda başvuru özellikleri, tedavi ve takip sonuçlarını retrospektif olarak inceledik.
Hastalar ve Metod: Ocak 2014-Temmuz 2018 tarihleri arasında tiroidektomi sonrası patoloji sonucu DTK olarak
raporlanan, postoperatif sintigrafide rezidü tiroid dokusu tespit edilmiş 187 (165 kadın, 22 erkek) hasta çalışmaya
dahil edildi. Yaş, cinsiyet, ultrasonografi bulguları, ince iğne aspirasyon biyopsi (İİAB) sonuçları, yapılan cerrahi girişimin
tipi, tümör çapı, multifokalite, postoperatif serum tiroglobulin (Tg) düzeyi, tiroid sintigrafisi, RAI ablasyonu ve
lokorejyonel rekürrens gibi parametreler Windows için SPSS 18.0 programı ile Mann Whitney-U, Kruskal Wallis ve
ki-kare testleri kullanılarak değerlendirildi. P değeri < 0,05 ise anlamlı kabul edildi.
Bulgular: Tüm hastaların tiroidektomi spesimenlerinin histopatolojik değerlendirme sonucu DTK iken, ameliyat öncesi
sadece 44’ünde (%24) İİAB sonucu malign ya da malignite şüphesi olarak raporlanmıştı. 45 yaşından büyük
hasta grubunda papiller tiroid mikrokarsinomu (PTMK) anlamlı olarak daha sık gözlendi (p <0,05). Cerrahi girişimin
tipi 110 (%59) olguda TT, 77 (%41) olguda TT+santral lenf nodu diseksiyonu (SLND) şeklinde idi. Non-insidental olgularda
postoperatif rezidü doku anlamlı olarak düşük sıklıkta bulundu. Rezidü doku, preoperatif ultrasonografide
2 cm’den büyük çapta veya ikiden fazla nodül saptanan olgularda anlamlı olarak daha sık izlendi. Olguların 106’sına
(%57) RAI ablasyonu uygulandı. Olguların 11’inde (%14) lenf nodu metastazı (LNM), 8’inde (%4,3) kapsül invazyonu
ve 10’unda (%5) ekstratiroidal yayılım gözlendi.
Sonuç: Multinodüler guatr yada Graves hastalığı gibi benign nedenlerle tirodektomi geçirmiş, patoloji sonucu DTK
olarak bildirilmiş hastalarda rezidü tiroid dokusu varlığına anlamlı olarak sık rastlanılmaktadır. Preoperatif dönemde
İİAB sonucu malign yada malignite şüphesi olarak bildirilmiş olgularda, nodül çapının 2cm’den büyük olması ya da
nodül sayısının ikiden fazla olması halinde postoperatif rezidü tiroid dokusu varlığı riski anlamlı yüksek bulunmuştur.

ABSTRACT
Aim: Postoperative radioactive iodine (RAI) ablation is one of the options for complementary treatment after
thyroidectomy of differentiated thyroid carcinoma (DTC). The evaluation of the residual tissue after thyroidectomy
is important for the effectiveness of RAI ablation. In our study, we evaluate the presentation and outcomes of the
patients with residual thyroid tissue and aimed to identify the risk factors related with the presence of the residual
thyroid tissue.
Patients and Methods: 187 (165 female, 22 male) patients, were reported as DTC and postoperative scintigraphy
revealed residual thyroid tissue between January 2014 and July 2018, were enrolled in the study. The parameters
including age, gender, ultrasonography findings, fine needle aspiration cytology (FNAC) reports, type of the surgery,
tumour diameter, multifocality, postoperative serum thyroglobulin (Tg) levels, thyroid scintigraphy, RAI ablation,
and locoregional recurrence were compared by Mann Whitney-U, Kruskal Wallis, and qi-square test in SPSS 18.0
for Windows software. P value is accepted as significant if below 0.05.
Results: Thyroidectomy specimens of all patients were reported as DTC, Preoperatively only in 44 (24%)
patients were reported as malign or suspicion of malignancy according to the results of FNAC. Papillary thyroid
microcarcinoma (PTMC) was significantly more common in the group of patients older than 45 (p <0.05). Surgical
intervention was performed as only TT in 110 (59%) cases, TT+central lymph node dissection (CLND) were done in
77 (41%) cases. Postoperative residual tissue was significantly more common in incidental cases. Residual tissue
was also significantly more common in cases with a nodule diameter longer than 2 cm and more than two nodules
on preoperative ultrasonographic evaluation.. RAI ablation was administered in 106 (57%) of the cases. Lymph
node metastasis (LNM) was observed in 11 (14%) cases, capsular invasion in 8 (4.3%) cases, and extrathyroidal
extension in 10 (5%) cases.
Conclusion: Risk of the presence of the residual thyroid tissue is found significantly high in patient with incidental
diagnosis. Patients have a thyroid nodul larger than 2cm or number of the thyroid nodules more than two carry a
significantly higher risk of the residual thyroid tissue
