"Latar Belakang: Karsinoma papiler tiroid KPT adalah karsinoma tersering 70 dari seluruh keganasan kelenjar tiroid. KPT varian folikular adalah varian terbanyak dari KPT yang menunjukkan diferensiasi sel folikular dengan perubahan inti. Well differentiated tumor of uncertain malignant potential WDT-UMP merupakan tumor berkapsul dengan pola pertumbuhan folikular difus dengan ciri inti karsinoma papiler yang tidak komplit, dan diperkirakan memiliki sifat borderline. KPTVF dan WDT-UMP sulit dibedakan terutama jika perubahan inti tidak secara difus ditemukan sehingga diperlukan metode diagnosis yang sederhana dan akurat dalam membedakan lesi borderline dan ganas, sehingga terapi yang berlebih dapat dihindari pada lesi borderline dengan prognosis baik.Bahan dan Metode: Penelitian ini menggunakan metode potong lintang. Sampel WDT-UMP dan KPTVF, masing-masing 20 kasus, diperoleh dari arsip Departemen Patologi Anatomik FKUI-RSCM pada tahun 2011-2015.

Background Papillary thyroid carcinoma PTC is the most common carcinoma 70 in all thyroid malignancy. The follicular variant of PTC FVPTC is the most frequent variant of PTC, which shows follicular cell differentiation with nuclear changes. Well differentiated tumor of uncertain malignant potential WDT UMP is an encapsulated tumor with incomplete nuclear features of PTC, estimated to be borderline in nature. It is hard to differentiate FVPTC and WDT UMP especially if the nuclear changes are not diffusely present, so a method which is simple and reliable, is needed to make an accurate diagnosis of borderline and malignant lesion, so overtherapy can be avoided, in borderline lesion with a good prognosis.Method This research use cross sectional methods. Twenty cases of WDT UMP and twenty cases of FVPTC, are obtainted from Anatomical Pathology Departement from 2011 2015. Immunochemistry staining with CK19 primary antibody, and scored semiquantitatively as follows 1 95 , strongly positive.Result In WDT UMP group, 15 cases expression score are 2 and 5 cases score 3. In FVPTC group, all of the cases are strongly positive, 9 cases score 3 and 11 cases score 4. Statistical analysis with Chi square test shows statistical significance difference between CK19 expression in WDT UMP and FVPTC p"

"Latar belakang: Karsinoma papiler tiroid merupakan kanker endokrin tersering dengan angka kejadian yang terus meningkat. Agresivitas dari karsinoma papiler tiroid salah satunya dipengaruhi oleh adanya ekstensi ekstratiroid yang dapat meningkatkan risiko rekurensi, metastasis kelenjar limfe dan metastasis jauh, sehingga memerlukan tatalaksana yang lebih agresif. Ultrasonografi (USG) merupakan modalitas pilihan dalam mendeteksi ekstensi ekstratiroid karena resolusi serta ketersediaan yang luas, tetapi USG memiliki operator-dependent dengan hasil false positive dan false negative yang cukup tinggi. Magnetic Resonance Imaging (MRI) merupakan modalitas yang penggunaannya semakin meningkat dalam mengevaluasi kelenjar tiroid dengan keunggulan memiliki kontras jaringan lunak yang baik serta memiliki kemampuan multiplanar. Telaah sistematis dan meta-analisis ini dibuat dnegan tujuan untuk membandingkan akurasi diagnostik USG dan MRI dalam menentukan ekstensi ekstratiroid pada karsinoma papiler tiroid. Metode: Pencarian sistematis dilakukan untuk mengidentifikasi studi yang membandingkan akurasi diagnostik USG dan MRI dalam menentukan ekstensi ekstratiroid dengan referensi baku pemeriksaan histopatologi melalui basis data PubMed, Scopus, Neliti dan Sinta serta grey literature menggunakan kata kunci yang telah ditentukan. Temuan yang diektraksi dari setiap studi terpilih adalah positif benar, positif palsu, negatif benar dan negatif palsu untuk menentukan nilai sensitivitas, spesifisitas, likelihood ratio (LR), dan diagnostic odds ratio (DOR) masing-masing uji indeks. Penilaian kualitas metodologi studi dilakukan dengan metode QUADAS-2, sedangkan penilaian kualitas bukti dilakukan menggunakan GRADE. Hasil: Pencarian sistematis mengindentifikasi 8 studi. Tiga studi diantaranya memiliki risiko bias yang tinggi dan studi lain setidaknya memiliki satu risiko bias yang tidak jelas pada salah satu domain. Sensitivitas, spesifisitas, LR+, LR- dan DOR USG secara berurutan adalah 85% (95% CI, 63-95%), 80% (95% CI, 73-86%), 4,3 (95% CI 3,3-5,7), 0,19 (95% CI 0,07-0,49) dan 23 (95% CI 8-65). Sensitivitas, spesifisitas, LR+, LR- dan DOR MRI secara berurutan adalah 84% (95% CI, 77-89%), 92% (95% CI, 86-96%), 10,9 (95% CI 6,1-19,7), 0,17 (95% CI 0,12-0,25) dan 64 (95% CI 31-132). Kualitas bukti rendah. Kesimpulan: MRI dan USG memiliki performa diagnostik yang hampir sebanding dalam menentukan ekstensi ekstratiroid. USG memiliki sensitivitas yang lebih tinggi, sedangkan MRI memiliki spesifisitas yang lebih tinggi. Secara keseluruhan, USG tetap disarankan menjadi modalitas awal, sedangkan MRI disarankan menjadi modalitas selanjutnya apabila temuan pada USG inkonklusif. Akan tetapi, penerapan temuan telaah sistematis dan meta-analisis ini terbatas karena keterbatasan pada kualitas metodologi dan kualitas bukti.

Background: Papillary thyroid carcinoma is one of the most endocrine cancer with increasing cases over three decades. Aggressive behaviour of papillary thyroid cancer is affected by extrathyroidal extension which could increase reccurency, lymph node metastases and distant metastases, hence need more aggressive treatment. Ultrasonography (USG) has good resolution for superficial organs and are modality of choice to evaluate extrathyroidal extension, but it is operator-dependent with high false positive dan false negative value. The use of Magnetic Resonance Imaging (MRI) to evaluate thyroid gland has increase. MRI provides superior soft tissue resolution with multiplanar view. This systematic review and meta-analysis are written to compare diagnostic accuracy of USG and MRI to determine extrathyroidal extension in papillary thyroid carcinoma. Methods: Studies which compared diagnostic accuracy of USG and MRI to determine extrathyroidal extension in papillary thyroid carcinoma with histopathological examination as reference standard were identified through PubMed, Scopus, Neliti dan Sinta and other grey literature using pre-determined keywords. Findings extracted from each eligible study included true positive, true negative, false positive and false negative to obtain sensitivity, specificity, likelihood ratio (LR) and diagnostic odds ratio (DOR). Methodological quality assessed using QUADAS-2 and evidence quality decided by GRADE. Results: Systematic search identified 8 studies. Three studies indicated high risks of bias and other studies at least have one unclear risk of bias in one domain. Sensitivity, specificity, LR+, LR- and DOR of USG were 85% (95% CI, 63-95%), 80% (95% CI, 73-86%), 4,3 (95% CI 3,3-5,7), 0,19 (95% CI 0,07-0,49) and 23 (95% CI 8-65). Sensitivity, specificity, LR+, LR- and DOR of MRI were 84% (95% CI, 77-89%), 92% (95% CI, 86-96%), 10,9 (95% CI 6,1-19,7), 0,17 (95% CI 0,12-0,25) and 64 (95% CI 31-132). The quality of evidence was low. Conclusion: MRI and USG has comparable diagnostic performance. USG has higher sensitivity, while MRI has higher specificity. USG still recommended as first modality, and MRI suggested when USG are inconclusive. However, application of this systematic review and meta-analysis are limited since methodological and evidence quality are also limited."
