Latar belakang: Karsinoma mukoepidermoid merupakan keganasan pada kelenjar liur yang paling sering ditemukan. Prognosis karsinoma mukoepidermoid berhubungan dengan derajat keganasannya. Cancer stem cell (CSC) diduga berperan dalam patogenesis karsinoma mukoepidermoid sehingga terjadi resisten terhadap berbagai terapi. CD44 merupakan salah satu penanda SC yang paling banyak pada kelenjar liur dan tampak meningkat pada karsinoma mukoepidermoid. Namun, peran prognostik CD44 pada keganasan masih menjadi perdebatan.

Metode: Penelitian menggunakan metode potong lintang. Sampel terdiri atas 34 kasus di Departemen Patologi Anatomik FKUI/RSCM tahun 2012 sampai 2017. Dilakukan pulasan CD44 dan perhitungan H-score dan presentasi setiap kasus. Hasil perhitungan dikelompokan menjadi ekspresi negatif/positif lemah dan positif kuat.

Hasil: Hasil penelitian menunjukkan bahwa ekspresi CD44 berhubungan secara signifikan dengan derajat keganasan (p=0,006). Ekspresi positif kuat ditemukan lebih banyak pada derajat keganasan rendah dan ekspresi negatif/positif lemah ditemukan lebih banyak pada derajat keganasan tinggi.

Kesimpulan: Ekspresi CD44 pada karsinoma mukoepidermoid berhubungan dengan derajat keganasan.

Background: Mucoepidermoid carcinoma is the most common malignancy in salivary gland. The prognosis correlates with its histological grading. Cancer stem cell (CSC) is predicted to have a role in pathogenesis of mucoepidermoid carcinoma, thus it make resistent to various therapy. CD44 is one of stem cell (SC) marker that expressed in salivary gland and seemed to be increased in mucopidermoid carcinoma. However, prognostic role of CD44 in malignancy still controversy.

Method: This is a cross sectionsl study. Samples consist of 34 cases from Anatomical Pathology Department, Faculty of Medicine Universitas Indonesia, Ciptomangunkusumo General Hospital in 2012 until 2017. CD44 staining was done and calculated wih H-score method. Then, the samples is catagorized into negative/weak expression and strong expresion.

Result: The result showed that CD44 expression associate significantly with histological grading (p=0,006). Strong expression is found more in low grade and negative/weak expresion is found more in high grade.

Conclusion: CD44 expression in mucoepidermoid carcinoma associates with histological grade.

ABSTRAK Preeklampsia merupakan sindrom sistemik yang terjadi pada 3-5 % kehamilan wanita yang disebabkan oleh gangguan faktor migrasi dan faktor seluler  yang berdampak pada gangguan diferensiasi dan invasi trofoblas yang penting dalam proses perkembangan plasenta dan mempertahankan kehamilan. Protein Cullin-1 merupakan salah satu kandidat protein yang berperan dalam proses mempertahankan kehamilan, perkembangan dan invasi trofoblas di dalam  plasenta. Hingga saaat ini belum ada penelitian yang menghubungkan ekspresi Cullin-1 pada pasien preeklampsia dengan waktu terminasi kehamilan. Oleh karena itu pada penelitian ini dilakukan analisis ekspresi Cullin-1 pasien preeklampsia dan hubungannya dengan waktu terminasi kehamilan. Sampel plasenta diambil dari pasien preeklampsia yang terdiri dari tiga kelompok usia kehamilan, kemudian dilakukan perwarnaan imunohistokimia untuk dilihat dinamika ekspresi dan distribusi Cullin-1 pada berbagai kelompok usia kehamilan dan hubungannya dengan waktu terminasi kehamilan. Cullin-1 terekspresi pada sinsitiotrofoblas dan  sitotrofoblas. Kadar Cullin-1 terendah didapatkan pada kelompok usia kehamilan very preterm, dan paling tinggi didapatkan di kelompok usia kehamilan moderate preterm. Terdapat perbedaan bermakna antara ekspresi optical density (OD) Cullin-1 dengan   waktu terminasi  kehamilan, dan terdapat perbedaan bermakna  (OD) Cullin-1 pasien preeklampsia usia kehamilan very preterm dengan usia kehamilan moderate preterm. Disimpulkan bahwa Cullin-1 terekspresi pada sinsitiotrofoblas dan sitotrofoblas dan berhubungan dengan waktu terminasi kehamilan.

ABSTRACT Preeclampsia is a systemic syndrome that occurs in 3-5% of female pregnancies caused by disorders of migration factors and cellular factors that have an impact on the disruption of trophoblast differentiation and invasion that is important in the process of developing the placenta and maintaining pregnancy. Protein Cullin-1 is one candidate protein that plays a role in the process of maintaining pregnancy, development and trophoblast invasion in the placenta. Until now there have been no studies linking the expression of Cullin-1 in preeclamptic patients with the timing of pregnancy termination. Therefore in this study an analysis of Cullin-1 expression in preeclamptic patients and their relationship to the timing of pregnancy termination was carried out. Placental samples were taken from preeclampsia patients consisting of three gestational age groups, then immunohistochemical staining was performed to see the dynamics of expression and distribution in each age group of pregnancy and to find out their relationship with  the timing of pregnancy termination. Cullin-1 was expressed in syncytiotrophoblasts and cytotrophoblasts. The lowest Cullin-1 level was obtained in the very preterm age group, and the highest was found in the moderate preterm gestational age group. There was a significant difference between Cullin-1 optical density (OD) expression and termination time of pregnancy, and there was a significant difference (OD) in Cullin-1 preeclamptic patients with very preterm gestational age with moderate preterm gestational age. It was concluded that Cullin-1 was expressed both in syncytiotrophoblasts and cytotrophoblasts and was associated with the timing of pregnancy termination.

Selanjutnya dilakukan pulasan imunohistokimia (IHK) protein 53 (p53) pada seluruh kasus dan dilakukan analisis untuk mengetahui ekspresi p53 pada variabel penelitian. Hasil: Ekspresi p53 ditemukan pada 35 kasus (85%). Berdasarkan derajat diferensiasi, ekspresi p53 ditemukan paling banyak pada derajat diferensiasi sedang dan buruk, yaitu 21 dan 14 kasus (91% dan 93%). Ekspresi p53 berdasarkan stadium patologi tumor ditemukan paling banyak pada pT1b dan pT2, yaitu 8 dan 14 kasus ( 88% dan 93%). Berdasarkan subtipe histologik, seluruh kasus macrotrabecular massive (MTM) menunjukkan ekspresi p53 (4 kasus, 100%), subtipe clear cell (CC) terpulas pada 15 kasus (93%), klasik (CL) ditemukan 16 kasus (88%) dan tidak ditemukan ekspresi p53 pada seluruh kasus steatohepatitic (SH). Terdapat perbedaan rerata bermakna ekspresi p53 pada kelompok baik dan sedang (p=0,011), baik dan buruk (p=0,015) dan tidak terdapat perbedaan rerata bermakna antara kelompok sedang dan buruk (p=0,339). Tidak ditemukan perbedaan rerata bermakna ekspresi p53 pada seluruh kelompok stadium patologi tumor (p=0,948) dan subtipe histologik (p=0,076). Kesimpulan: Terdapat perbedaan bermakna ekspresi p53 pada KSH kelompok diferensiasi baik dan sedang serta baik dan buruk. ......Background: Hepatocellular cell carcinoma (HCC) is the most common malignant neoplastic lesion of the liver. Malignant transformation of hepatocytes involves various factors such as inflammation and genetic causing HCC to be very heterogeneous at the histological and molecular level. Differences in phenotypes affected by various molecular changes produce different differentiation grade, histological subtype, clinical features and prognosis. TP53 as one of the most common molecular changes in HCC play an important role in cycle cell by controlling cell proliferation through DNA repair, apoptosis and cellular senescence, associates with several risk factors such as certain differentiation grade, histologic subtypes, and prognosis. This current study aimed to investigate p53 expression at HCC’s differentiation grade, tumor pathology stage and histologic subtype. Materials and methods: The study was conducted at the Department of Anatomical Pathology FKUI / RSCM, Jakarta on 41 cases of resected HCC. Case samples are classified based on groups of differentiation grade (WHO), histologic subtypes and tumour pathology stage. Furthermore immunohistochemical (IHC) staining of protein 53 (p53) carry out in all cases and an analysis statistic was performed to evaluated the expression of p53. Results: p53 expression was found in 35 cases (85%). Based on the differentiation grade, the expression of p53 was found mostly in the moderate and poor differentiation (91%, 21 cases and 93%, 14 cases). Based on tumour pathology stage, p53 expression was found mostly in pT1b and pT2, which were 8 and 14 cases (88% and 93%). Based on histologic subtypes, all macrotrabecullar massive (MTM) cases showed p53 expression (4 cases, 100%), clear cell (CC) subtypes were in 15 cases (93%), classic (CL) 16 cases (88%) and negative expression was found in all cases of steatohepatitic (SH). There were significant differences in mean expression of p53 in the well and moderate groups (p = 0.011), well and poor (p = 0.015) and there were no significant mean differences between the moderate and poor groups (p = 0.339). There were no significant mean differences in p53 expression in all groups of tumour pathology stages (p = 0.948) and histologic subtypes (p = 0.076). Conclusion: There is significant difference mean of p53 expression in well and moderate as well as well and poor differentiation.
