"Kanker nasofaring (KNF) merupakan kanker leher kepala terbanyak di Indonesia (28,4%) dan sebagian besar terdiagnosis pada stadium lanjut. Modalitas pengobatan pada kasus KNF stadium lanjut adalah kemoterapi dan radioterapi. Namun, pada stadium sama, respon terhadap pengobatan memiliki hasil berbeda dikarenakan adanya perbedaan karakteristik biologi molekular. Cyclin D1 adalah protein yang berperan dalam siklus sel. Peningkatan ekspresi cyclin D1 akan mempercepat proliferasi. Penelitian ini ingin mengetaui tingkat ekspresi cyclin D1 terhadap respons kemoterapi. Hal tersebut berdasarkan perbedaan hasil penelitian terdahulu. Data ekspresi cyclin D1 pada KNF di Indonesia belum ada, sehingga perlu penelitian ekspresi cyclin D1 pada KNF serta hubungannya berdasarkan respons pengobatan. Metode: Penelitian ini menggunakan studi kohort retrospektif dengan subjek merupakan pasien KNF yang berobat di RSCM pada kurun waktu 2015-2018. Gambaran radiologi sebelum dan sesudah pengobatan ditinjau ulang berdasarkan kriteria RECIST. Pewarnaan imunohistokimmia cyclin D1 menggunakan antibodi monoklonal cyclin D1 NovocastraTM dengan teknik pengambilan antigen suhu tinggi dan intensitasnya dinilai dengan H-skor menurut kriteria Allred. Hasil: Terdapat 16 subjek (51,6%) dengan ekspresi cyclin D1 positif dan 15 subjek (48,4%) dengan ekspresi negatif. Peneliti menemukan bahwa ekspresi cyclin memiliki perbedaan rerata yang bermakna antara kelompok subjek yang respons (rerata 116,24 ± 57,80) dan tidak respons (rerata 77,97 ± 45,27) terhadap pengobatan (p = 0,048). Simpulan: Penelitian ini menunjukkan ekspresi cyclin D1 yang kuat pada kelompok dengan respons pengobatan yang baik.

Nasopharyngeal cancer (NPC) is the most type of head and neck cancer in Indonesia (28.4%) and mostly diagnosed at advanced stage. Treatment of this stage is chemotherapy and radiotherapy. However, patients with the same stage of disease had different treatment response probably due to different characteristics of molecular biology. Cyclin D1 is a protein involved in cell cycle, which the overexpression of it will fasten proliferation. Studies regarding the association of cyclin D1 expression and chemotherapy response have shown a different result. In Indonesia, data of cyclin D1 expression of NPC do not yet exist. This study aimed to examine the proportion of cyclin D1 in NPC and its association with treatment response. Methods: A retrospective cohort study was conducted using subjects of NPC patients at Cipto Mangunkusumo Hospital from 2015 until 2018. The response of treatment was reviewed based on RECIST criteria. The technique used for cyclin D1 immunohistochemistry staining was antigen retrieval methods, using cyclin D1 NovocastraTM monoclonal antibody and the intensity was assessed based on Allred criteria. Results: Sixteen subjects (51.6%) had positive expression of cyclin D1 and 15 subjects (48.4%) had negative expression. The researchers found that cyclin D1 expression had significant mean differences between groups of subjects who responded (mean ± SD = 116.24 ± 57.80) and did not respond (mean ± SD = 77.97 ± 45.27) to treatment (p = 0.048). Conclusion: This study suggests that higher expression of cyclin D1 is associated with a good treatment response in NPC patients."

"Latar Belakang: Karsinoma narofaring (KNF) termasuk kanker dengan prevalensi yang cukup tinggi di Indonesia dengan prognosis yang cukup. Dalam menentukan progresifitas suatu kanker, didapatkan peranan penting dari penurunan tumor supresor gen dan peningkatan proliferasi. Hal tersebut ditandai oleh marker p53 sebagai gen supresor yang menginduksi apoptosis dan Ki67 sebagai marker proliferasi sel. Hingga saat ini belum terdapat penelitian mengenai hubungan overekspresi p53 dan Ki67 terhadap respon kemoradiasi dan analisis kesintasan selama 3 tahun pada KNF stadium lokal lanjut. Tujuan: Mencari hubungan antara overekspresi p53 dan Ki67 terhadap respon kemoradiasi dan kesintasan 3 tahun pasien KNF stadium lokal lanjut. Metode: Penelitian ini merupakan penelitian analitik observasional dengan desain analisis kesintasan. Penelitian ini menggunakan desain penelitian kohort retrospektif, dengan pengambilan data dari rekam medis kemudian ditelusuri riwayat perjalanan penyakitnya. Sample penelitian berupa jaringan pada blok parafin pasien KNF stadium lokal lanjut yang diambil secara consecutive sampling dari populasi penelitian dari periode 2015–2017 di RSUPN Dr. Cipto Mangunkusumo sejumlah 82 orang. Hasil: Dari total 82 pasien KNF stadium local lanjut, terdapat 65 pasien kelamin laki – laki (79,3%) dan 17 pasien perempuan (20,7%), dengan usia paling banyak pada kelompok 41 – 50 tahun sebanyak 31,8%. Overekspresi p53 ditemukan pada 36 pasien (43,9%), sementara overekspresi Ki67 ditemukan pada 35 pasien (42,7%). Dari respon kemoradiasi, pasien dengan overekspresi p53 dan Ki67 berpeluang memberikan respon negatif yang lebih tinggi dibandingkan dengan low ekspresi (RR = 3,052 dengan IK95%: 1,777 – 5,242, p = 0,009; RR = 2,573 dengan IK95%: 1,547 – 4,297, p = 0,002 berturut-turut). Dinilai dari kesintasan 3 tahun, pasien dengan overekspresi p53 memiliki kesintasan 3 tahun yang lebih buruk dibandingkan dengan low ekspresi (HR = 19,827 dengan IK95%: 5,974 – 65,798, p = <0,001). Begitu juga dengan overekspresi Ki67 memiliki kesintasan 3 tahun yang lebih rendah.

Background: Naropharyngeal carcinoma (NPC) is a cancer with a fairly high prevalence in Indonesia with a fairly poor prognosis. Tumor supressor gene and cancer proliferation played an important roles in determining the progression of a cancer. This was indicated by the marker p53 as a suppressor gene that induces apoptosis and Ki67 as a marker of cell proliferation. There has been limited research on the relationship of p53 and Ki67 overexpression to the chemoradiation response and 3-year survival in locally advanced NPC. Objective: To determine the relationship between p53 and Ki67 overexpression with chemoradiation response to therapy and 3-year survival in locally advanced NPC patients. Methods: This research is an observational analytic study with a survival analysis design. This study used a retrospective cohort study design, by collecting data from medical records and then tracing the history of the disease. The research sample was tissue in the paraffin block of locally advanced NPC patients taken by consecutive sampling from the study population from period 2015–2017 at Dr. Cipto Mangunkusumo National Hospital with a total number of 82 patients.
Results: From a total of 82 patients with locally advanced NPC, there were 65 male patients (79.3%) and 17 female patients (20.7%), with the most age being in the 41-50 years group as many as 31.8 %. Overexpression of p53 was found in 36 patients (43.9%), while overexpression of Ki67 was found in 35 patients (42.7%). Based on therapy response, patients with overexpression of p53 and Ki67 had a higher chance of giving a negative response compared to those with low expression (RR = 3,052 with IK95%: 1,777 – 5,242, p = 0,009; RR = 2,573 with IK95%: 1,547 – 4,297, p = 0,002 respectively). Assessed by 3- year survival, patients with p53 overexpression were statistically significantly worse than those with low-expression (HR = 19,827 with IK95%: 5,974 – 65,798, p = <0,001). Likewise, Ki67 overexpression was statistically significant and had a lower 3-year survival compared to low Ki67 expression (HR = 14,634 with IK95%: 5,074 – 42,204, p = <0,001). Conclusion: Locally advanced NPC patients with p53 overexpression and Ki67 overexpression have a tendency to give a negative chemoradiation response and have a lower 3-year survival.

"Latar Belakang: Kanker nasofaring (KNF) adalah keganasan yang terjadi pada epitel mukosa daerah nasofaring dengan angka kejadian di dunia sekitar 1,2 per 100.000 penduduk. Perkembangan mekanisme penanda molekuler yang berhubungan dengan proliferasi, apoptosis, dan invasi tumor yaitu Ki-67 dan p16, dapat memberikan indikasi tentang tingkat proliferasi sel dan status penghambatan siklus sel.
Metode: Penelitian ini menggunakan disain kohort retrospektif dengan subjek pasien KNF stadium local lanjut yang berobat di RSCM pada periode 2015-2020. Penelusuran data klinis dilakukan bersamaan dengan pewarnaan imunohistokimia p16 dan Ki-67 menggunakan antibodi monoklonal. Ekspresi dihitung secara manual menggunakan piranti imageJ. Analisis hubungan p16 dan Ki-67 terhadap progression-free survival (PFS) 3 tahun menggunakan kurva Kaplan Meier dan uji log rank dengan batas kemaknaan p<0,05.
Hasil: Angka PFS 3 tahun pada subjek sebesar 44% dengan median 29 bulan. Ekspresi p16-negatif dideteksi pada 56 (56,0%) sampel, dan peningkatan ekspresi Ki-67 pada 53 (53,0%) sampel. Kurva Kaplan-Meier menunjukkan PFS 3 tahun untuk p16-negatif yaitu 8,9% (p<0,0001). PFS untuk peningkatan ekspresi Ki-67 11,3% (p<0,0001).
Simpulan: Penelitian ini menunjukkan pasien KNF stadium ocal lanjut dengan peningkatan ekspresi Ki-67 dan p16-negatif memiliki progression-free survival 3 tahun yang lebih rendah.

Background: Nasopharyngeal cancer (NPC) is a malignancy that occurs in the mucosal epithelium of the nasopharyngeal area with a worldwide incidence of around 1.2 per 100,000 population. To date, the development of molecular marker mechanisms, including Ki-67 and p16 which are related to proliferation, apoptosis, and tumor invasion can indicate the level of cell proliferation and status of cell cycle inhibition.
Methods: A retrospective cohort study was conducted in subjects of NPC patients at RSCM from 2015 until 2020. Clinical data was collected from hospital registries, and immunohistochemistry staining of Ki-67 and p16 was perfomed by using monoclonal antibody. The expression of Ki-67 and p16 were calculated manually using the imageJ tool. Association of Ki-67 and p16 expression with 3 years- progression-free survival (PFS) was analyzed using Kaplan Meier with log-rank test p<0.05.
Results: The 3-years PFS in subjects was 44% with a median of 29 months. p16-negative expression was detected in 56 (56,0%) samples, and Ki-67 overexpression in 53 (53,0%) samples. The Kaplan-Meier curve shown the 3-years PFS for p16-negative was 8,9 (p<0,0001). PFS for Ki-67 overexpression was 11,3%, (p<0,0001).
Conclusion: This study shows that locally advanced NPC patients with Ki-67 overexpression and p16-negative have lower 3-year progression-free survival.

"Latar Belakang: Kanker nasofaring (KNF) merupakan jenis keganasan yang paling umum terjadi di wilayah kepala dan leher di Indonesia. Saat ini, terjadi pergeseran paradigma ke konsep tumor microenvironment, yang menekankan pentingnya penanda biologis. Rasio limfosit monosit (RLM) mencerminkan Tumor-Infiltrating Lymphocytes (TIL) dan Tumor- Associated Macrophages (TAM). Namun, temuan penelitian tentang RLM, TIL CD8, dan TAM CD163 sebagai prediktor untuk Progression-Free Survival (PFS) masih kontroversial. Belum ada penelitian yang menyelidiki hubungan antara marker-marker ini dan PFS 3 tahun pada pasien KNF stadium lokal lanjut di Indonesia.
Tujuan: Mengetahui PFS 3 tahun pada pasien KNF stadium lokal lanjut dan mengetahui hubungan antara RLM, TIL, dan TAM dengan PFS 3 tahun.
Metode: Studi kohort retrospektif yang dilakukan di Rumah Sakit Cipto Mangunkusumo (RSCM) selama periode Januari 2015 hingga 2020. Kami menghimpun data mengenai karakteristik demografis pasien, menghitung RLM, dan pewarnaan imunohistokimia untuk TAM CD163 dan TIL CD8 pada blok biopsi jaringan. Analisis penentuan nilai titik potong dilakukan melalui kurva receiver operating curve (ROC) untuk ketiga ini. Setelahnya, kami melakukan analisis terhadap ketiga parameter tersebut terkait PFS 3 tahun dengan menggunakan kurva Kaplan-Meier dan uji log rank. Untuk mengatasi variabel perancu, dilakukan uji Cox Regression.
Hasil: Didapatkan persentase PFS 3 tahun KNF stadium lokal lanjut sebesar 46,7%. Nilai titik potong terbaik untuk RLM, CD163, dan CD8 berturut – turut adalah 1,82, 1,96, dan 47,5%. Berdasarkan analisis bivariat dan multivariat, didapatkan RLM ≤ 1,82 (aHR 1,785, IK95% 1,057 – 3,018), CD163 ≥196 (aHR 6,126, IK95% 3,382 – 11,097), dan CD8 ≤47,5% (aHR 2,099, IK95% 1,232 – 3,575).
Simpulan: Nilai RLM dan TIL CD8 yang tinggi berhubungan dengan PFS 3 tahun yang baik, sedangkan TAM CD163 yang tinggi berhubungan dengan PFS 3 tahun yang buruk pada pasien KNF lokal lanjut.

Background: Nasopharyngeal cancer (NPC) is the most common malignancy in the head and neck region in Indonesia. Recently, there has been a paradigm shift towards the concept of the tumor microenvironment, emphasizing the significance of biological markers. The lymphocyte-to-monocyte ratio (LMR) reflects Tumor-Infiltrating Lymphocytes (TILs) and Tumor-Associated Macrophages (TAMs). However, findings on LMR, CD8 TILs, and CD163 TAMs as predictors for Progression-Free Survival (PFS) remain controversial. No study has yet investigated the relationship between these markers and 3-year PFS in patients with advanced local-stage NPC in Indonesia.
Objective: To determine the 3-year PFS in patients with advanced local-stage NPC and to ascertain the relationship between LMR, TILs, and TAMs with 3-year PFS.
Methods: A retrospective cohort study was conducted at Cipto Mangunkusumo Hospital (RSCM) from January 2015 to 2020. We gathered data on patient demographic characteristics, calculated LMR, and performed immunohistochemical staining for CD163 TAMs and CD8 TILs on tissue biopsy blocks. The determination of cutoff values was performed using receiver operating curve (ROC) analysis for all three. Subsequently, we analyzed these parameters in relation to 3-year PFS using Kaplan-Meier curves and log-rank tests. Cox Regression analysis was conducted to adjust for confounding variables.
Results: The 3-year PFS rate for advanced local-stage NPC was found to be 46.7%. The optimal cutoff values for LMR, CD163, and CD8 were 1.82, 1.96, and 47.5%, respectively. Based on bivariate and multivariate analyses, we found LMR ≤ 1.82 (aHR 1.785, 95% CI 1.057 – 3.018), CD163 ≥196 (aHR 6.126, 95% CI 3.382 – 11.097), and CD8 ≤47.5% (aHR 2.099, 95% CI 1.232 – 3.575).
Conclusion: High LMR and CD8 TIL values are associated with favorable 3-year PFS, while high CD163 TAM values are associated with poor 3-year PFS in patients with advanced local-stage NPC.

"Latar belakang: Juvenile Nasopharyngeal Angiofibroma (JNA) merupakan tumor jinak nasofaring yang bersifat hipervaskular, agresif lokal, dan destruktif. Pencitraan sebelum pembedahan untuk menentukan ukuran dan perluasan tumor, serta embolisasi preoperatif dapat mempengaruhi jumlah perdarahan intraoperatif, yang merupakan salah satu faktor morbiditas pada pasien JNA. Penelitian ini bertujuan untuk menilai pengaruh karakteristik tumor antara lain ukuran tumor, staging, dan pembuluh darah yang memperdarahi tumor, serta efek dari embolisasi preoperatif terhadap jumlah perdarahan intraoperatif.
Metode: Penelitian dilakukan pada pasien JNA yang menjalani embolisasi preoperatif dan operasi pengangkatan tumor di Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo sejak tahun 2018 hingga Maret 2022. Dilakukan penilaian ukuran tumor dan staging, serta identifikasi feeding artery menggunakan CT/MRI dan juga DSA embolisasi preoperatif, kemudian dilakukan analisis perbandingan dan korelasi terhadap jumlah perdaran intraoperatif.
Hasil: Terdapat 21 pasien JNA yang menjalani embolisasi preoperatif dan pengangkatan tumor. Didapatkan perbedaan jumlah perdarahan intraoperatif yang bermakna antara pasien JNA stadium III dibandingkan dengan stadium I-II (p=0,006). Jumlah perdarahan intraoperatif lebih banyak pada tumor yang berukuran lebih besar, namun didapatkan korelasi yang lemah (R=0,43; p=0,051). Jumlah perdarahan intraoperatif juga berbeda bermakna pada tumor JNA dengan feeding artery dari kedua sisi arteri maksilaris interna dengan tumor JNA yang mendapatkan feeding artery satu sisi arteri maksilaris interna saja (p=0,009), serta keterlibatan feeding artery dari cabang arteri karotis interna (p=0,023). Persentase pembuluh darah yang dilakukan embolisasi preoperatif, juga mengurangi jumlah perdarahan intraoperatif (R=-0,36; p=0,113).
Kesimpulan: Pencitraan preoperatif pada pasien JNA memegang peranan penting dalam menentukan perluasan tumor (staging), ukuran tumor, dan feeding artery yang berpengaruh terhadap jumlah perdarahan intraoperatif pada pasien JNA. Tindakan embolisasi preoperatif juga memiliki peranan penting dalam mengurangi jumlah perdarahan intraoperatif

Background: Juvenile Nasopharyngeal Angiofibroma (JNA) is a benign tumor of the nasopharynx that is hypervascular, locally aggressive, and destructive. Imaging before surgery to determine the size and extent of the tumor, as well as preoperative embolization can affect the amount of intraoperative bleeding, which is one of the morbidity factors in JNA patients. This study aimed to assess the effect of tumor characteristics such as tumor size, staging, and blood vessels supplying the tumor, as well as the effect of preoperative embolization on the amount of intraoperative bleeding.
Methods: The study was conducted on JNA patients who underwent preoperative embolization and surgical removal of tumors at the Cipto Mangunkusumo National General Hospital from 2018 to March 2022. Tumor size and staging were assessed, as well as identification of feeding arteries using CT/MRI and DSA preoperative embolization, then we performed a comparative and correlation analysis of the amount of intraoperative bleeding.
Results: There were 21 JNA patients who underwent preoperative embolization and tumor removal. There was a significant difference in the amount of intraoperative bleeding between patients with stage III JNA compared to stage I-II (p = 0.006). The amount of intraoperative bleeding was higher in larger tumors, but a weak correlation was found (R=0.43; p=0.051). The amount of intraoperative bleeding was also significantly different in JNA tumors with feeding arteries from both sides of the internal maxillary artery compared to JNA tumors with feeding arteries on one side of the internal maxillary artery only (p=0.009), and the involvement of feeding arteries from the internal carotid artery branch (p=0.023). The percentage of vessels that underwent preoperative embolization also reduced the amount of intraoperative bleeding (R=-0.36; p=0.113).
Conclusion: Preoperative imaging in JNA patients plays an important role in determining tumor expansion (staging), tumor size, and feeding arteries that affect the amount of intraoperative bleeding in JNA patients. Preoperative embolization also have an important role in reducing the amount of intraoperative bleeding.

"Latar belakang: kanker nasofaring (KNF) adalah keganasan yang umum dijumpai pada nasofaring. Cukup banyak bukti menunjukkan adanya keterkaitan KNF dengan sistem kekebalan tubuh. Tidak semua subset sel T merupakan sel T efektor. Sel T regulator (TReg) yang merupakan salah satu subset dari sel T, memiliki peran penting dalam mengatur imunitas anti tumor. Sampai saat ini belum dapat disimpulkan bahwa keberadaan sel TReg pada lokasi tumor pasti akan memicu pertumbuhan tumor. Akan tetapi, adanya sel T CD4+ dan CD8+ tentunya berpengaruh terhadap kontrol perkembangan tumor. Studi ini bertujuan untuk menilai karakterisitik CD4, CD8 dan FOXP3 pada pasien KNF dan hubungannya terhadap agresivitas tumor.
Metode: penelitian ini merupakan studi kohort prospektif. Sel TReg dinilai menggunakan marker FOXP3. Jumlah protein CD4, CD8 dan FOXP3 pada jaringan biopsi tumor dideteksi dan diukur dengan ELISA. Volume tumor primer dan volume total metastasis kelenjar getah bening regional didapatkan dari proses delineasi dengan pencitraan 3D. Spearmen-rho test digunakan untuk menilai korelasi antara CD4, CD8 dan FOXP3 dengan volume tumor primer dan volume total metastasis kelenjar getah bening regional.
Hasil: Sebanyak 23 subjek penelitian (14 pria dan 9 wanita) terkumpul berdasarkan kriteria inklusi dan eksklusi. Stadium KNF terbanyak pada studi ini adalah stadium IV (AJCC edisi ke-8). Analisis dengan uji Spearman menunjukkan korelasi kuat antara konsentrasi protein FOXP3 dan volume tumor primer (p=0.02, r=0.60), dan juga antara konsentrasi protein CD8 dan volume tumor primer (p=0.00, r=0.81). Menariknya, juga ditemukan korelasi antara konsentrasi CD8 dan FOXP3 (p=0.00, r=0.85). Tidak ditemukan korelasi antara konsentrasi protein CD4, CD8 dan FOXP3 dengan volume total metastasis kelenjar getah bening regional. Tidak ditemukan juga korelasi antara konsentrasi FOXP3 dan stadium KNF. Sayangnya, belum dapat disimpulkan hubungan antara konsentrasi FOXP3 dan respons terapi pada penelitian ini.
Kesimpulan: Keberadaan sel TReg berpengaruh terhadap agresivitias lokal tumor yang ditandai dengan peningkatan volume massa tumor primer. Korelasi antar konsentrasi CD4, CD8 dan FOXP3 memberikan gambaran interaksi dan mekanisme respons imunitas tubuh dalam menjaga keseimbangan antara sel T efektor dan sel T regulator.

Background: nasopharyngeal cancer (NPC) is a common malignancy found in the nasopharynx area. There is quite a lot of evidence showing a link between NPC and the immune system. Regulatory T cells (TReg), a subset of T cells, have an essential role in regulating anti-tumor immunity. It has not been confirmed that TReg cells at the tumor site will trigger tumor growth. However, the presence of CD4+ and CD8+ T cells certainly affects the control of tumor growth. This study aims to assess the characteristics of CD4, CD8, and FOXP3 in NPC patients and their relationship with tumor aggressiveness.
Methods: a prospective cohort study was conducted on 23 subjects (14 men and 9 women) based on the inclusion and exclusion criteria. TReg cells were assessed using the FOXP3 marker. The number of CD4, CD8, and FOXP3 proteins in tumor biopsy tissue was detected and measured by ELISA kit (MBS2702975, MBS165145, MBS162054). The volume of the primary tumor and the total volume of regional lymph node metastases were obtained from the delineation process based on 3D imaging. Spearmen-rho test was used to assess the correlation of CD4, CD8, and FOXP3 with primary tumor volume and total volume of regional lymph node metastases.
Results: A total of 23 study subjects (14 men and 9 women) were collected based on the inclusion and exclusion criteria. The most common NPC stage in this study was stage IV (AJCC 8th edition). Analysis by the Spearman-rho test showed a strong correlation between; concentration of FOXP3 protein and primary tumor volume (p=0.02, r=0.60) and the concentration of CD8 protein and primary tumor volume (p=0.00, r=0.81). Interestingly, a correlation was also found between the concentration of CD8 protein and FOXP3 (p=0.00, r=0.85). There was no correlation between CD4, CD8, and FOXP3 proteins and the total volume of regional lymph node metastases. There was also no correlation between FOXP3 concentration and NPC stage. Unfortunately, it is impossible to conclude the relationship between FOXP3 concentration and treatment response in this study.
Conclusions: the presence of TReg cells affects the local aggressiveness of the tumor, which is characterized by an increase in the volume of the primary tumor. The correlation between CD4, CD8, and FOXP3 concentrations provides an overview of the interactions and mechanisms of the body's immune response to maintain a balance between effector T cells and regulatory T cells.

"Latar belakang: Karsinoma nasofaring (KNF) merupakan keganasan tersering di regio kepala leher. Terapi utama KNF adalah radiasi karena sifatnya yang radiosensitif, namun rekurensi lokal dan metastasis banyak terjadi. Cancer stem cell (CSC) diduga sebagai salah satu penyebabnya. Octamer binding transcription factor 4 (OCT4) merupakan salah satu penanda sel punca embrionik yang penting dalam progresi keganasan berbagai organ, termasuk nasofaring. Namun peran OCT4 sebagai prediktor respons terapi KNF masih menjadi perdebatan.
Metode: Penelitian ini menggunakan metode potong lintang. Sampel berjumlah 41 kasus di Departemen Patologi Anatomik FKUI/RSCM periode Januari 2014 sampai Desember 2016. Dilakukan pulasan imunohistokimia OCT4 dan penilaian terhadap perbedaan rerata proporsi ekspresi positif kuat dan sedang OCT4 pada kelompok respons dan non-respons.
Hasil: Terdapat 33 kasus (80,5%) dengan jenis kelamin laki-laki dan 8 kasus (19,5%) dengan jenis kelamin perempuan. Berdasarkan data klinik, 13 kasus (31,7%) berada dalam rentang usia 40-49 tahun, gejala terbanyak ditemukan berupa benjolan leher pada 31 kasus (75,6%) dan 18 kasus (43,9%) berada pada stadium IVA. Ditemukan perbedaan bermakna (p = 0,009) antara rerata proporsi ekspresi OCT4 positif kuat dan sedang kelompok respons (61,29%) dibandingkan kelompok non respons (37%).
Kesimpulan: Kesimpulan penelitian ini adalah ditemukan hubungan bermakna antara ekspresi OCT4 dengan respons kemoradiasi KNF tidak berkeratin tidak berdiferensiasi.

Background: Nasopharyngeal carcinoma (NPC) is the most common head and neck malignancy with high rate of resistance and recurrence. Cancer stem cells (CSC) is considered responsible for cancers relapse and metastasis because of its self-renewal capabilities. Expression of embryonic stem cells marker Octamer binding transcription factor 4 (OCT4) is crucial for progression of various human malignancies, including NPC. But the role of OCT4 as therapy response predictor is controversial.
Method: This study is using cross-sectional method. Sample consist of 41 undifferentiated non keratinizing NPC cases diagnosed in Anatomical Pathology Departement, Faculty of Medicine, Universitas Indonesia-Dr. Cipto Mangunkusumo Hospital from January 2014 until December 2016. OCT4 immunohistochemistry staining was performed then tumour cells with strongly and moderately positive OCT4 staining were counted. Mean difference between both groups is calculated.
Result: There were 33 male cases (80,5%) of 41 and 8 female cases (19,5%). 13 cases (31,7%) were age 40-49 years old. Neck mass was the most common symptom in 31 cases (75,6%) and 18 cases (43,9) were in stadium IVA. Mean difference of strongly and moderately positive OCT4 expression between responsive (61,29%) and non-responsive (37%) to chemoradiation therapy were statically significant (p=0.009).

"Praktek residensi Keperawatan Medikal Bedah peminatan Onkologi yang telah dilaksanakan di RS Kanker Dharmais menetapkan satu kasus kelolaan utama yaitu karsinoma nasofaring dan 30 kasus resume kasus-kasus kanker dengan menggunakan pendekatan teori peaceful end of life. Saat melakukan praktek residensi telah dilakukan berbagai rangkaian kegiatan yang berhubungan dengan permasalahan pasien kanker yaitu dengan memberikan asuhan keperawatan secara professional dan komprehensif kepada pasien-pasien kanker dan salah satu diantaranya adalah kanker nasofaring dengan menggunakan pendekatan teori peaceful end of life., melakukan suatu penerapan intervensi keperawatan yang berdasarkan Evidence Based Nursing yaitu intervensi kombinasi progressive muscle relaxation dan guided imagery untuk mengatasi mual muntah akibat kemoterapi pada pasien kanker payudara dan penerapan suatu proyek inovasi yaitu untuk mengatasi fatigue pada pasien kanker, dimana hampir sebagian besar pasien kanker mengalami fatigue sehingga penerapan intervensi Walking Exercise dengan menggunakan aplikasi J-HATI (Jalan Sehat Berenergi) diharapkan dapat meningkatkan kualitas hidup pasien kanker.

Medical Surgical Nursing residency practice specializing in Oncology which has been carried out at Dharmais Cancer Hospital establishes one main managed case, namely nasopharyngeal carcinoma and 30 cases of resume cancer cases using a peaceful end of life theory approach. During residency practice, various series of activities related to the problems of cancer patients have been carried out, namely by providing professional and comprehensive nursing care to cancer patients and one of them is nasopharyngeal cancer by using a peaceful end of life theory approach, implementing an intervention. nursing based on Evidence-Based Nursing, namely a combination intervention of progressive muscle relaxation and guided imagery to treat nausea, vomiting due to chemotherapy in breast cancer patients and the implementation of an innovative project, namely to overcome fatigue in cancer patients, where most of the cancer patients experience fatigue so that the implementation of the Walking intervention Exercise using the J-HATI (Energy Healthy Walk) application is expected to improve the quality of life of cancer patients."

"Pendahuluan
Karsinoma nasofaring (KNF) merupakan jenis keganasan yang unik dengan distribusi geografis dan etnis tertentu. Daerah Cina Selatan dan Asia Tenggara memiliki insidens kejadian yang tinggi. Indonesia memiliki insidens 5,66 kasus per 100.000 penduduk per tahun. Salah satu penyebab kematian pasien dengan keganasan adalah trombosis. Kadar soluble Platelet-selectin (sP-selectin) yang tinggi dalam plasma, hasil dari aktivasi sel-sel endotel dan trombosit, adalah prediktor kejadian trombosis.
Tujuan
Mengetahui kadar sP-selectin pada berbagai stadium karsinoma nasofaring dan korelasinya dengan hitung trombosit.
Metode
Dilakukan studi potong lintang pada 60 kasus karsinoma nasofaring yang baru terdiagnosis di Rumah Sakit Cipto Mangunkusumo pada periode Maret hingga November 2012. Kadar sP-selectin diukur dengan teknik Enzyme Linked Immunosorbent Assay.
Hasil
Rerata usia adalah 43,9 tahun dengan rasio laki-laki terhadap perempuan 3:1. Jenis patologi terbanyak adalah karsinoma tidak berdiferensiasi (83,3%). Sepuluh persen pasien mengalami trombositosis. Median kadar sP-selectin adalah 45,73 ng/mL dengan rentang interkuartil: 42,02-57,66 ng/mL. Secara statistik terdapat perbedaan kadar sP-selectin diantara stadium IVC dengan stadium lainnya (stadium IVB, p = 0,001 dan kelompok stadium I-IVA, p < 0,001). Hitung trombosit tidak berkorelasi dengan sP-selectin (r: 0,185; p = 0,158).
Simpulan
Terdapat perbedaan kadar sP-selectin pada berbagai stadium karsinoma nasofaring. Hitung trombosit tidak berkorelasi dengan kadar sP-selectin.

Background
Nasopharyngeal carcinoma (NPC) is an unique malignancy because of its geographical and ethnic patterns. South China and South East Asia have the highest incidence, while in Indonesia is about 5.66 cases per 100,000 populations per year. Thrombosis is one of the complications of malignancy. High plasma levels of soluble Platelet-Selectin (sP-selectin) produced by activated endothelial cells and platelets, are predictive of thrombosis.
Objective
To measure sP-selectin levels in various stages of nasopharyngeal carcinoma and its correlation with platelet count.
Methods
This was a cross sectional study including 60 patients with newly diagnosed nasopharyngeal carcinoma at Cipto Mangunkusumo Hospital, Jakarta, Indonesia in period of April to November 2012. Soluble P-selectin levels in various stages of NPC measured with Enzyme Linked Immunosorbent Assay was compared and correlated with platelets count.
Results
From 60 patients of NPC, the mean age was 43.9 years with ratio of men to women was 3:1. The most prevalence histopathology was undifferentiated carcinoma (83.3%). Ten percent of the patients had thrombocytosis. The median level of sP-selectin was 45.73 ng/mL (inter quartile range: 42.02-57.66). Soluble P-selectin levels were statistically significantly higher among patients with stage IVC than other stages (with stage IVB, p = 0.001 and with group of stage I-IVA, p < 0.001). There was no correlation between platelet count and sP-selectin levels (r = 0.185; p = 0.158).
Conclusion
There were different levels of sP-selectin between various stages of nasopharyngeal carcinoma. There was no correlation between platelets count and sP-selectin levels.
