"ABSTRACTAdenoid cystic carcinoma (ACC) is one of the common malignant tumors in salivary glands, and the clinical prognosis is poor with frequent distant metastasis which may lead to death. Expression of the MYB-NFIB chimeric gene in ACC has been reported recently. MYB is an oncogene with transcription regulating functions, and NFIB encodes nuclear transcription factor although detailed functions are unknown. This study investigated whether MYB-NFIB chimeric gene expression affects tumor angiogenesis and proliferation in salivary gland ACC. In 26 salivary gland ACC cases, MYB-NFIB chimeric gene expression was analyzed by RT-PCR and direct sequencing. Immunohistochemical studies for CD31, vascular endothelial growth factor (VEGF) and Ki-67 were performed. Tumor angiogenesis was evaluated by blood vessel (CD31-positive) density and tumor proliferation by Ki-67 labeling index, and the relationship with MYB-NFIB chimeric gene expression was analyzed. MYB-NFIB chimeric gene expression was detected in nine of 26 ACC cases. Blood vessel density was significantly higher in chimeric gene-expressing cases compared to non-expressing cases. VEGF score tended to be higher in chimeric gene-expressing cases than in non-expressing cases, while Ki-67 labeling index was not significantly different. The number of chimeric gene-expressing cases increased with age, peaking in the sixties age group and declining thereafter, while the number of non-expressing cases increased with age continuously. In ACC, blood vessel density was significantly higher in MYB-NFIB chimeric gene-expressing cases compared to non-expressing cases, which may be due to higher VEGF production capability. MYB-NFIB chimeric gene expression may also be related to the onset age of ACC."

"Adenoid cystic carcinoma is an extremely rare case of the esophagus. We present a female patient, aged 76 years who present with dysphagia and weight loss for tire last three month. On endoscopy there was a luminal narrowing in the middle third of the esophagus. Diagnosis was challenging due to the stenosis and the tumor size. Histopathological confirmation was obtained by subcarinal fine-needle aspiration biopsy. This type of cancer is very aggressive with short survival time. Further studies are needed to define optimal treatment."

The treatment response was evaluated from the nasopharyngeal CT scan, before and after definitive therapy, using the unidimensional measurement based on the change in sum longest diameter.

Result: The expression of Rad51 immunostaining assessed by the H-score were strongly correlate with the regression of the tumor mass which represent the treatment response. The p value is 0,005 and the correlation’s coefficient is -0,64.

Conclusion: There is significant correlation with negative magnitude between the expression of Rad51 with the shrinkage of tumor mass in nasopharyngeal carcinoma."

"Receptor activator of nuclear factor-kappa (RANK)/receptor activator of nuclear factor-kappa B ligand (RANKL) signaling helps putative cancer stem cells (CSC) to maintain their stemness. Expression of CD44 and RANKL was analyzed in oral squamous cell carcinoma specimen (n = 191). Moreover, RANKL expression was measured in cancer cell lines (BICR3, BICR56) by immunohistochemistry and western blot analysis. Scanned images were digitally analyzed using ImageJ and the immunomembrane plug-in. CD44 and RANKL expression on protein level was correlated with clinical characteristics and impact on survival. RANKL was co-labeled with CD44 in immunohistochemical and immunofluorescence double labeling experiments. Although high CD44+/RANKL+ co-expression was significantly associated with clinicopathological factors and worse survival, multivariate analysis did not demonstrate high CD44+/RANKL+ co-expression as independent prognostic factor. Immunohistochemical and immunofluorescence double labeling experiments revealed RANKL expression by CD44+ cancer cells. RANKL specificity was confirmed by western blot analysis. For the first time, this study provides evidence that RANKL expression in OSCC might be associated with disease recurrence and a cell compartment measured by CD44+/RANKL+ co-expression within the mucosal epithelial basal layer cells."

"Latar belakang: Karsinoma sel hati (KSH) merupakan jenis keganasan primer hatitersering dengan gambaran histologik menunjukkan diferensiasi sel hepatoselular. Selaininsiden yang tinggi, beban yang berat dari keganasan ini adalah prognosis yang sangatburuk dengan angka rekurensi yang tinggi. Terdapat banyak faktor resiko secaraklinikopatologik yang telah diketahui mempengaruhi prognosis KSH, seperti kadar alfafetoprotein, derajat diferensiasi, dan invasi mikrovaskular.

Background: Hepatocellular carcinoma (HCC) is the most common primary livercancer, displaying histologically hepatocellular differentiation. In addition to its highincidence, the disease burden of HCC is due to its poor prognosis with high recurrencerate. Some of the previously known clinicopathologic prognostic factors of HCC includealpha-fetoprotein (AFP) level, tumor grade and microvascular invasion. At molecularlevel, p53 and β-catenin are the two most common driver mutations in HCC that aremutually exclusive. β-catenin is a multifunction protein that is encoded by CTNNB1 gen.It is found in 3 compartments of cells, which are membrane cell, cytoplasm and nucleus.Wnt/ β-catenin pathway regulates cellular process which is related to initiation, growth,survival, migration, differentiation and apoptosis. Although molecular pathogenesispathways of hepatocarcinogenesis are known, clinical application warrants moreunderstanding in terms of molecular characteristic and tumor phenotype, especially indetermining prognosis and target therapy development. This current study aims to analyzethe expression of β-catenin and its association with prognostic factors, such as AFP,tumor grade and microvascular invasion.Material and method: A cross-sectional study was conducted comprising 35 samples ofsurgically resected HCCs between January 2013 to September 2019 in CiptoMangunkusumo General Hospital. The cases were diagnosed based on histopathologicaland immunohistochemical findings and was then performed β-catenin staining. β-cateninexpression was analyzed with statistical tests to determine expression difference betweenAFP level, tumor grade and microvascular invasion.Result: There were statistically significant difference of β-catenin expression in AFPlevel and tumor grade (p=0.037 and 0.043, respectively). Nuclear with/withoutcytoplasmic expression of β-catenin was more frequently found in HCC with low AFPlevel and well-to-moderately differentiated tumors. No significant difference wasobserved in β-catenin expression between HCC with and without microvascular invasion(p=1.000).Conclusion: β-catenin expression was significantly different in AFP level and tumorgrade."

"Latar belakang: Buah Merah (Pandanus conoideus Lam.) merupakan salah satu kekayaan biodiversitas alam Indonesia khas Papua yang sejak lama dikonsumsi sebagai makanan dan dikenal memiliki khasiat obat antara lain terhadap penyakit keganasan. Namun disisi lain, dasar ilmiah cara pengobatan tersebut belum diketahui secara pasti sehingga perlu dilakukan penelitian bagi pembenaran ilmiah pemakaian tanaman obat tersebut.

Background: Red Papua (RP) is one of the Indonesian natural properties. Originally, RP comes from Papua province. It is consumed by Papua people as daily food since a long time ago. RP is considered to be cancer medicine, particularly for breast cancer treatment. Alternatively, the justification on the use of RP as an anti cancer has not been established yet. Hence, scientific evidence on anticancer effect of RP is necessary. The previous study suggests that Red Papua Oil (RPO) contains a huge amount of carotene and of tocopherol. Some studies indicate that tocopherol can inhibit the growth of human breast cancer cell culture by prohibiting of DNA synthesis, induction of cell differentiation and apoptosis. Carotene reduces the rate of growth of breast tumor, improves gene expression of pro-apoptosis and p53 of BAX, degrades gene expression of anti-apoptosis Bcl-2, and increases the ratio of BAX: BCL-2. P53 gene can induce arrest cycle cell so that it enables cells to repair the DNA and generate apoptosis.Aims: to identify the influence of RPO intake of 0,5m1, 1m1, and 2ml doses per oral on apoptosis and its effect on tumor growth in mammary gland tumor of C3H strain mouse.Method: Twenty-four mice were randomly divided into four groups, three groups of RPO-treated groups and one control group. After tumor was transplanted, the three doses of RPO were given to the three groups. By twenty-eight day treatment, apoptosis and proliferation activities were measured_ TUNEL essay was used to detect apoptotic activity_ The tumor growth, which was determined by proliferation activity, was assessed by a histochemical technique, AgNOR (silver-staining nucleolar organizer regions). Statistical significance of Apoptosis Index (AI) and AgNOR value in control and groups treated with varied doses of RPO were calculatedResults and Conclusion: Variant analysis indicated that there was no significant difference of volume, weight and AI among control group and treated groups (p>0.05). However, there was a tendency to an increased apoptotic activity on the treated groups. On the contrary, AgNOR values were significantly different (p"

"Latar Belakang: Ekspresi PD-L1 sering ditemukan pada keganasan yang terkait dengan virus Epstein-Barr (EBV) seperti karsinoma nasofaring. Studi terbaru menunjukkan bahwa keganasan terkait EBV memiliki tingkat ekspresi PD-L1 yang tinggi. Tetapi mekanisme yang mendasari regulasi PD-L1 dan EBV terhadap ekstensi tumor masih kurang dipahami. Beberapa literatur menghubungkan parameter ini dengan tumor stadium lanjut dan prognosis buruk. Studi ini akan menilai konsentrasi PD-L1 dan DNA EBV pada jaringan tumor, pada pasien kanker nasofaring di populasi Indonesia yang dikumpulkan secara konsekutif dan dikorelasikan dengan ekstensivitas tumor. Metode: Kami menggunakan imunohistokimia dan ELISA untuk menilai PD-L1 dan reaksi rantai polimerase (PCR) juga dilakukan untuk menilai konsentrasi DNA EBV (EBNA-1 sebagai primer). Delineasi tumor dilanjutkan dengan perhitungan volumetrik menggunakan Eclipse Treatment Planning System. Semua pemeriksaan dilakukan pra terapi. Kami memperoleh data kuantitatif dan kualitatif. Kurva korelasi didapatkan menggunakan uji korelasi Pearson.  Hasil: Tidak ada korelasi antara DNA EBV dan ekstensivitas kanker nasofaring dengan ekspresi PD-L1 positif (p = 0,371). Lebih lanjut, tidak ada korelasi antara DNA EBV dan PD-L1.  Kesimpulan: Berapapun banyaknya tumor viral load DNA EBV dan konsentrasi PD-L1 tidak akan berpengaruh pada ekstensivitas tumor. Ini adalah studi pendahuluan.

Background: PD-L1 expression is often found in malignancies associated with Epstein-Barr virus (EBV) such as nasopharyngeal carcinoma. Recent studies shown that EBV-related malignancies have high levels of PD-L1 expression. But the mechanism underlying the regulation of PD-L1 and EBV DNA against tumor extension is still poorly understood. Some literature links this parameter with advanced tumors and poor prognosis. This study will assess tumor tissue PD-L1 and EBV DNA concentrations in nasopharyngeal cancer patients in the Indonesian population collected consecutively and correlate with tumor extensivity. 

Methods: We used immunohistochemical and ELISA to assess PD-L1 and polymerase chain reaction is also performed to assess the EBV DNA concentrations (EBNA-1 as primary). Tumor volume delineation continued with volumetric calculation using Eclipse treatment planning system. All examinations were carried out pre therapy. Quantitative and qualitative data was obtained. Correlation curves were estimated using the Pearson correlation test. 

Results: There was no correlation between EBV DNA and nasopharyngeal cancer extension with positive PD-L1 expression (p = 0.371). Furthermore, there is also no correlation existed between the EBV DNA copy and PD-L1. 

Conclusion: No matter how much tumor EBV DNA viral load and PD-L1 concentrations had no effect on tumor extensivity. This is a preliminary study."

"Latar Belakang: Karsinoma nasofaring (KNF) adalah karsinoma yang berasal dari epitel permukaan nasofaring dengan angka insidensi yang tinggi di Tiongkok dan Asia Selatan. KNF masih menjadi masalah kesehatan di Indonesia dan prognosisnya dilaporkan buruk terkait dengan penanganan yang sering tidak optimal karena kebanyakan (60-95%) pasien berobat dalam stadium lanjut. Saat ini berkembang penelitian terhadap tumor microenvironment yang dapat dinilai melalui tumor infiltrating lympochyte (TIL) yang berkaitan dengan respons terapi pada beberapa tumor, termasuk KNF. Beberapa penelitian menyebutkan bahwa TIL salah satunya dapat dinilai dengan Foxp3. Foxp3 diketahui sebagai penanda sel T regulator (Treg) yang turut berperan dalam immunoregulator lingkungan sel-sel tumor dan dapat digunakan sebagai salah satu faktor prognosis. Hubungan antara ekspresi Foxp3 dengan respons terapi dapat dipertimbangkan menjadi salah satu faktor yang mempengaruhi prognosis KNF.Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan antara ekspresi Foxp3 dengan respons terapi karsinoma nasofaring.Metode: Penelitian analitik dengan desain potong lintang pada sediaan KNF tidak berkeratin di Departemen Patologi Anatomik FKUI/RSCM selama periode Januari 2018 hingga Desember 2020. Pengambilan sampel penelitian dilakukan secara consecutive sampling dari kasus yang memenuhi kriteria inklusi dan eksklusi sesuai perhitungan besar sampel untuk masing-masing kelompok. Pemeriksaan imunohistokimia menggunakan antibodi primer monoklonal Foxp3. Data imunoekspresi dianalisis untuk mengetahui hubungannya dengan respons terapi karsinoma nasofaring.Hasil: Dari 60 kasus yang terdiagnosis KNF, sebanyak 40 kasus (66,7%) berjenis kelamin laki-laki dan 20 kasus lainnya (33,3%) berjenis kelamin perempuan dengan rasio 2:1. Terdapat perbedaan bermakna ekspresi Foxp3 intratumoral dengan respons terapi (p=0,01). Tidak terdapat perbedaan bermakna ekspresi Foxp3 peritumoral dengan respons terapi (p=0,114).Kesimpulan: Ekspresi Foxp3 mempunyai hubungan yang bermakna secara statistik dengan hasil evaluasi respons pasca kemoradiasi karsinoma nasofaring.

Background: Nasopharyngeal carcinoma (NPC) is a carcinoma originating from the surface epithelium of the nasopharynx with a high incidence in Tiongkok and South Asia. NPC still become main health issue in Indonesia and the prognosis is reported to be poor due to suboptimal treatment because most of the patients (60-95%) are treated at an advanced stage. Currently, many research are developing on the tumor microenvironment that can be assessed by tumor infiltrating lymphochyte (TIL) which is associated with the treatment response in several tumors, including NPC. Some studies explore that TIL can be assessed with Foxp3. Foxp3 is known as a regulatory T cell (Treg) marker that plays a role in the immunoregulator environment of tumor cells and can be used as a prognostic factor. The relationship between Foxp3 expression and treatment response can be considered as one of the factors that influence the prognosis of NPC.

Aims: This study aims to determine the relationship between Foxp3 expression and treatment response of NPC.

Methods: An analytical study with a cross-sectional design on non-keratinizing NPC diagnosed at Anatomical Pathology Department of FKUI/RSCM during January 2018 until December 2020. The research sample was taken by consecutive sampling of cases that met the inclusion and did not include the exclusion criteria according to the calculation of the sample size for each group. Immunohistochemical examination using Foxp3 monoclonal antibody. Immunoexpression data were analyzed to determine its relationship with the treatment response of NPC.

Results: From 60 selected cases diagnosed with NPC, there were consisted of 40 male patients (66,7%) and 20 female patients (33,3%) with ratio 2:1. There was a significant difference in intratumoral Foxp3 expression with treatment response (p=0.01). There was no significant difference in peritumoral Foxp3 expression with treatment response (p=0.114).

Conclusion: Foxp3 expression had a statistically significant relationship with response therapy after chemoradiation."
