"ABSTRAKDalam usaha untuk meningkatkan ketajaman diagnosis potong beku jaringan tiroid diperlukan beberapa pemeriksaan tambahan, antara lain dengan sitologi imprint. Pembuatan sediaan sitologi imprint ini cukup mudah dan cepat. Dengan sitologi imprint, sel ganas pada umumnya lebih mudah dikenali daripada sediaan potong beku, kecuali pada kelainan tertentu terutama Iasi folikuler. Tujuan penelitian adalah untuk mendapatkan nilai ketepatan keganasan dengan metode sitologi imprint pada jaringan tiroid terhadap diagnosis sediaan parafin dari kasus yang sama.Penelitian ini dilakukan dua tahap.Pertama meneliti semua sediaan imprint yang telah dipersiapkan selama dua tahun. Kedua meneliti sediaan parafin kasus yang sama. Semua sediaan imprint diteliti baik mengenai sel maupun latar belakangnya. Dibuat kriteria tertentu untuk tiap jenis kelainan tiroid.Untuk menilai ketepatan diagnosis sitologi imprint diperlukan analisa uji kemampuan yaitu menggunakan angka acak binomial dengan menirukan tabel 2 x 2 dan sediaan paraffin sebagai baku emas. Dari uji dengan sediaan paraffin sebagai baku emas menghasilkan: sensitifitas 75%, spesifisitas 100%, nilai ramalan positif 100%, nilai ramalan negatif 76% dan ketepatan 93,88%.Dari hasil penelitian tersebut disimpulkan bahwa sitologi imprint mempunyai ketepatan tinggi dalam hal membedakan antara kelainan tiroid jinak dan ganas. Sitologi imprint berguna sebagai pemeriksaan tambahan pada potong beku jaringan tiroid.

ABSTRACT

To increase the ability diagnosis of frozen section of thyroid lesion we need some additional examinations, for example, imprint cytology. In making cytology preparation is not difficult. With imprint cytology, the detail of cell are better preserved than that in frozen section. Usually the malignant cell is rather well differentiated, except for follicular lesions.

The aim of research is to get a value of accuracy of imprint cytology diagnosis of thyroid malignancy, compared with paraffin section diagnosis from the same cases.

There are two investigations for this research. First we evaluated all imprint slides prepared in two years. All the imprint slides where examined of their cells and backgrounds. We made some criteria for each thyroid lesions. The second evaluation was about paraffin slides.

To evaluate the imprint cytology diagnosis accuracy, analysis of capability was necessary, using binomial random numbers, imitating table 2 x 2 and paraffin slide as gold standard.

From the analysis we found that sensitivity was 75%, spesificity was 100%, positive predictive value was 100%, negative predictive value was 76% and accuracy was 93,88%.

From this examination we conclude that imprint cytology has high accuracy in distinguishing malignancy lesions from benign ones. The imprint is valuable as an addition to the frozen section."

ABSTRACTBackgroud: Papillary Thyroid Carcinoma (PTC) is the most common malignantneoplasm of the endocrine organ with an excellent prognosis, but in some casespresent with recurrency and mortality. There are prognostic factors and BRAFV600E mutation that related to worse prognosis. Immunohistochemicalinvestigetion of BRAF V600E protein believe can detect mutation wth 100%specificity and 89% sensitivity. Recent study suggest PTC with BRAF V600Emutation do thyroidectomy with prophylactic lymph node dissection. BRAFV600E specific inhibitor effective to the patient with advance stadium, patientwith metastases, and resistant to iodium radioactive. Aim of this study is to obtainBRAF V600E and the relation with prognostic factors.Material and Methods: This is a retrospective descriptive-analytic crosssectionalstudy. Fifty patient with PTC comes from Ciptomangunkusumo Hospitaland reviewed to determine prognostic factors microscopicaly. BRAF V600Emutation detected by immunohistochemical staining and assesed with H score.Result: H score ³ 326,5 determined as positive BRAF V600E mutation and <326,5 as negative BRAF V600E mutation. BRAF V600E mutation was detectedin 17 (34%) cases by immunohistochemistry. The mean age of the cases withpositive BRAF V600E mutation was 44.71 years, while the negative 41.58. Thesize of the tumor in cases with BRAF V600E mutation positive range between0,1-4cm, while negative 0,1-9cm. Seventeen cases have mutations, 6 of them sexmale and 11 female. Seven cases with extrathyroidal extension (ETE), 11 caseswith lymph node metastasis (KGB), and 8 cases with tall cell variant.Conclusion: There are significant correlation between BRAF V600E mutationwith extrathyroidal extension, lymph node metastases, and tall cell variant. Thereare no significant correlation between BRAF V600E mutation with age, gender,and size of the tumor, Backgroud: Papillary Thyroid Carcinoma (PTC) is the most common malignantneoplasm of the endocrine organ with an excellent prognosis, but in some casespresent with recurrency and mortality.

"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. Pewarnaan imunohistokimia dengan antibodi primer CK19, dan dinilai secara semikuantitatif dengan skor 1 95 , positif kuat.Hasil: Didapatkan 15 kasus terekspresi 2 dan 5 kasus 3 pada WDT-UMP, sementarra 9 kasus terekspresi 3 dan 11 kasus terekspresi 4 pada KPTVF. Hasil analisis dengan uji Chi square, menunjukkan terdapat perbedaan yang bermakna antara ekspresi imunohistokimia CK19 dengan diagnosis WDT-UMP dan KPTVF, dengan nilai p.

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"
