"ABSTRAK Karsinoma sel skuamosa kepala leher (KSSKL) menempati peringkat ke-6  kanker tersering di seluruh dunia.  Perkembangan  dalam  hal  terapi yang menggunakan  beragam modalitas untuk mengontrol  lokal dan  regional masih belum dapat meningkatkan angka survival lima tahun yang hanya sekitar 50% selama tiga dekade terakhir.  Metastasis jauh  menjadi penyebab utama  morbiditas dan  mortalitas pada KSSKL.  Sebagian besar pasien dengan metastasis jauh tidak terdeteksi secara klinis dan  radiologi.  Hingga saat ini sistem staging dan radiologi konvensional tidak mampu mendeteksi metastasis sejak dini . Mikrometastasis  merupakan proses awal dari suatu makrometastasis, sehingga sel tumor yang bersirkulasi dianggap sebagai silent predictor. Deteksi  CTC dianggap sebagai metode yang inovatif, sensitif, dan spesifik untuk dapat memprediksi kemungkinan terjadinya metastasis pada pasien-pasien  KSSKL. Penelitian ini menggunakan 90 sampel darah pasien penderita KSSKL stadium I-IV yang berobat di poli Bedah Onkologi dan THT RSUPNCM  pada periode Januari hingga Desember 2018.  Sampel darah  sebanyak 8 ml dikirim ke Laboratorium Patologi Klinik FKUI/RSUPNCM untuk dianalisa jumlah CTC -nya dengan  menggunakan flow cytometry, penanda epitel EpCAM dan CK19 serta penanda lekosit CD45. Analisa statistik dilakukan untuk mengetahui ada tidaknya asosiasi antara status klinikohistopatologi pasien KSSKL dengan deteksi CTC. Flow cytometry mampu  mendeteksi CTC positif sebanyak 28 dari 90 sampel darah (31.1%). Dari analisa bivariat dan multivariat, tidak didapatkan adanya asosiasi yang bermakna antara status klinikohistopatologi pasien KSSKL dengan deteksi CTC (p>0.05).    Pasien dengan stadium lanjut  memiliki kecenderungan 4.192 kali untuk mendapatkan CTC positif dibandingkan dengan stadium awal. Begitu pula pasien  yang memiliki sublokasi  tumor di daerah  faring  dan  laring   memiliki  kecenderungan 2.634 kali  untuk mendapatkan CTC positif bila dibandingkan dengan sublokasi anatomi bibir, rongga mulut, hidung dan sinus paranasal. Flow cytometry mampu mendeteksi CTC pada KSSKL dengan presentase 31.1%  bila menggunakan dua penanda epitel. Tidak terdapat asosiasi yang bermakna antara status klinikohistopatologi pasien KSSKL dengan deteksi CTC. Diperlukan studi lanjutan untuk meningkatkan sensitivitas dan spesifisitas serta mengkonfirmasi dapat tidaknya CTC dipakai sebagai prediktor dan prognostikator di bidang KSSKL.

ABSTRACT

HNSCC is the sixth most common cancer worldwide. The therapy of choice for newly diagnosed patients consists of combined modality treatment for locoregional control. Despite of improvement in treatment, for all stages combined, the 5-year survival rate is approximately 50% and this rate has not changed significantly in the last 3 decades. As distant metastases develop, the chance for cure becomes low and survival decreases. Tumor metastasis is an important contributor to mortality in cancer patients. Mostly distant metastases are not seen by clinical examination and/ or conventional imaging. To date, TNM staging  system and  the existing image technology are not sufficient to detect tumor metastasis in early stages. The concept of the development of metastasis involves a tumor cell that dissociates from the primary tumor (micrometastasis) and circulates within lymphatic or vascular channels. The true utility of a circulating tumor cell (CTC) is that it acts as a silent predictor of metastatic disease. Detection of CTCs serves as an innovative, sensitive and specific marker and providing early and definitive evidence of metastatic disease. In this study, peripheral blood samples from 90 patients with SCCHN stage I-IV from Surgical Oncology and ENT OPD were taken. CTCs were quantified using flow cytometry of anti-EpCAM, CK19 and CD45. Their detection was correlated with clinicohistopathologic characteristics. CTCs were identified in 28 (31.1%) patients at any time point with a mean + standard deviation of  0.9 + 3.2 CTCs. In bivariate and  multivariate analysis, we observed no significant correlation between the presence of CTCs and clinicohistopathologic characteristics (p>0.05). However the odds for the patients with advanced stages to have positive CTCs  is 4.192 times higher than early stage. Moreover, patients with pharynx and larynx cancer have the odds 2.634 times higher than those with lips, oral cavity and paranasal sinuses cancer. The rate of CTCs detection in HNSCC by flow cytometry was 31.1%. Detection of CTCs does not correlate with any clinicohistopathological characteristics. Further studies is needed to increase the sensitivity and specificity  and  also to confirm the potential of CTC to serve as a predictor and prognosticator in patients with HNSCC."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV:239-242Oral squamous cell carcinorna ( OSCC ) is the most common malignant tumor of the oral cavity, and its account for 80-90% of all malignancies in oral cavity. The aim of this study was to detemine the presenceof p53 mutations and to associate these mutations with the histopathological type of OSCC such as well differentiated and poorly differentiated. Analitycal observational comparative study by cross sectional design was used. Forty untreated well and poorly differentiated OSCC biopsy sample and normal tissue biopsy material taken from 16 normal patients were analyzed for the presence of mutation in the conserved region of the p53 gene especially in exon 5 by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP). The results of this study showed that p53 gene mutations were detected in exon 5; 11/40 (27,5%) with heterozygous mutation 9/11 (81,8%). The incidence in exon 5 of p53 gene mutation was significantly accociated with well differentiated 2/20 (l0%) and poorly diferentiated 9/20 (45%) OSCC(P=0,013). This study concludes that 1) mutation in exon 5 of p53 gene occured frequently in OSCC; 2) exon 5 of the p53 gene could be one of the the specific targets for histopathological grade of OSCC; 3) mutation in exon 5 of p53 gene could be important prognostic factor in OSCC."

"belakang: Karsinoma sel skuamosa rongga mulut (KSSRM) adalah salah satu kanker yang paling umum dijumpai dengan angka survival 52.0% yang tidak meningkat secara bermakna walaupun tatalaksana kanker ini terus berkembang. Cornulin merupakan protein spesifik untuk sel skuamosa yang penting dalam diferensiasi epitel. Penelitian sebelumnya menunjukkan bahwa rendahnya ekspresi cornulin berhubungan dengan gambaran klinikopatologi dan survival yang lebih buruk dibandingkan dengan ekspresi tinggi. Oleh karena sifatnya yang spesifik dan belum ada penelitian mengenai ekspresi cornulin sebagai faktor prognosis di Indonesia, maka penulis tertarik untuk mengetahui hubungan antara ekspresi cornulin dan survival pada pasien dengan KSSRM.Tujuan: Mengetahui potensi cornulin sebagai penanda biologis survival pada pasien dengan KSSRM.Metode: Penelitian ini menggunakan desain studi kohort retrospektif yang dilakukan dari periode Juni 2021 sampai dengan Mei 2022. Populasi penelitian ini merupakan pasien dengan diagnosis KSSRM yang ditegakkan dengan pemeriksaan histopatologis dan menjalani terapi di Divisi Bedah Onkologi Departemen Ilmu Bedah RSCM periode Januari 2015 – Mei 2020. Pemeriksaan imunohistokimia dilakukan untuk mengetahui ekspresi cornulin dan skor imunihistokimia ditentukan menggunakan immunoreactive score (IRS). Skor IRS < 6 berarti ekspresi rendah dan ≥ 6 berarti ekspresi tinggi. Analisis statistik univariat, bivariat, dan survival dilakukan menggunakan perangkat lunak SPSS.Hasil: Cornulin tidak memiliki hubungan yang signifikan secara statistik dengan survival pada pasien dengan KSSRM. T, N, dan stadium memiliki hubungan yang signifikan secara statistik dengan survival pada pasien dengan KSSRM dengan nilai p masing-masing adalah 0.001, 0.040, dan 0.001. T dan N memiliki hubungan yang bermakna secara statistik dengan ekspresi cornulin pada pasien dengan KSSRM, dengan nilai p masing-masing adalah 0.034 dan 0.030.Kesimpulan:Cornulin sebagai protein penanda biologis KSSM tidak dapat menjadi prediktor dari survival pasien dengan KSSM.

Background: Oral squamous cell carcinoma (OSCC) is one of the most common cancers with a 52.0% survival rate which does not increase significantly even though the management of this cancer continues to develop. Cornulin is a specific protein for squamous cells that is important in epithelial differentiation. Previous studies have shown that low cornulin expression is associated with worse clinicopathological features and survival compared to high cornulin expression. Due to its specific nature and no research on cornulin expression as a prognostic factor has been done in Indonesia, the author is interested in knowing the relationship between cornulin expression and survival in patients with OSCC.

Objective: To determine the potential of cornulin as a biological marker for survival in patients with OSCC.

Methods: This study used a retrospective cohort study design that was conducted from June 2021 to May 2022. The population of this study were patients with OSCC diagnosis confirmed by histopathological examination and undergoing therapy at the Division of Surgical Oncology, Department of Surgery, RSCM for the period January 2015-May 2020. Immunohistochemical examination was performed to determine the expression of cornulin and the immunohistochemical score was calculated using the immunoreactive score (IRS). IRS score < 6 means low cornulin expression and ≥ 6 means high cornulin expression. Univariate, bivariate, and survival statistical analyses were performed using SPSS software.

Results: Cornulin did not have a statistically significant relationship with survival in patients with OSCC. T, N, and stage had a statistically significant relationship with survival in patients with SCC with p values ​​of 0.001, 0.040, and 0.001, respectively. T and N had a statistically significant relationship with cornulin expression in patients with OSCC, with p-values ​​of 0.034 and 0.030, respectively.

Conclusion: Cornulin as a biological marker protein of OSCC cannot be a predictor of the survival of patients with OSCC."

"Latar belakang Kanker rongga mulut dan mulut (termasuk karsinoma sel skuamosa rongga mulut/KSSRM) secara kolektif tetap menjadi kanker paling umum ke-16 di dunia. Karena kecenderungan stadium lanjut selama diagnosis, kelangsungan hidup pasien KSSRM sangat buruk.

Background Oral cavity and mouth cancer (including oral cavity squamous cell carcinoma (OCSCC) collectively remain the 16th most prevalent cancer in the world. Due to the tendency of advanced stage during diagnosis, the survival of OCSCC patients is abysmal. The connection of OCSCC and expressed tumor infiltrated lymphocytes (TILs) is thought to affect the survivability of the OCSCC patients, including CD8+ and other TILs. Aim To determine the expression of CD8+ and TILs in OCSCC cells and their relationship with overall survival (OS) and progression-free survival (PFS) of OCSCC patients. Methods This study is a survival analysis using retrospective cohort design on OCSCC patients who came to Cipto Mangunkusumo National General Hospital, Indonesia, from January 2017 to December 2021. The inclusion criterion of the study was OCSCC patients with histopathological diagnosis, while the exclusion criteria were patients with incomplete data or unavailability of the samples. The expression of CD8+ and TILs were measured by manual counting of cells using ImageJ® on immunohistochemistry staining. The OS and PFS were analyzed using Kaplan-Meier graph and cox-regression analysis. Result A total of 42 subjects were included in this study. The average OS was 10.83+1.268 months, while the average PFS was 9.74+1.229 months. The 2-years OS was 21.4%, while PFS was 19%. Higher CD8+ expression was related to better OS and PFS, while higher expressed TILs was related to better PFS. Conclusion Higher CD8+ and TILs expressions in cancer cells are related to better survivability in OCSCC patients. "

"Latar belakang: Peran nilai ADC sebagai biomarka imaging pada KSS kepala leher telah banyak diteliti namun nilai ADC belum digunakan rutin untuk memandu manajemen pasien karena tingginya heterogenitas hasil penelitian terdahulu. Teknik ROI pada peta ADC merupakan salah satu faktor yang memengaruhi hasil pengukuran nilai ADC. Belum diketahui bagaimana kesesuaian metode ROI single largest slice (ROIsls) dan small sample (ROIss) terhadap ROI whole volume (ROIwv) dalam menentukan nilai ADC pada KSS rongga mulut. Metode: 138 pasien KSS rongga mulut selama bulan Januari 2019 hingga September 2023 yang memenuhi kriteria penelitian dilakukan pengukuran nilai mean dan minimum ADC tumor menggunakan ROIwv, ROIsls, dan ROIss. Nilai mean dan minimum ADC tumor yang dinormalisasi terhadap nilai mean dan minimum ADC medulla spinalis juga disajikan. Analisis kesesuaian ketiga metode ROI dilakukan dengan uji korelasi.. Hasil: Median nilai mean ADC tumor berdasarkan ROIwv, ROIsls, dan ROIss berturut-turut adalah 1,210, 1,190, dan 0,910 mm2/s. Median minimum ADC tumor berdasarkan ROIwv, ROIsls, dan ROIss adalah 0,730, 0,640, dan 0,770 mm2/s. Mean ADC ROIsls memiliki korelasi positif kuat dengan mean ADC ROIwv (r = 0,846, p < 0,05). Minimum ADC ROIsls memiliki korelasi positif sedang dengan minimum ADC ROIwv (r = 0,773, p < 0,05). Terdapat korelasi positif sedang antara mean ADC ROIss dan ROIwv (r = 0,565, p < 0,05), serta antara minimum ADC ROIss dan ROIwv (r = 0,767, p < 0,05). Normalisasi parameter ADC tumor terhadap parameter ADC medulla spinalis tidak menyebabkan perubahan signifikan pada kekuatan korelasi Kesimpulan: Pengukuran nilai ADC berdasarkan metode ROIsls dapat digunakan sebagai alternatif ROIwv dan lebih terpilih dibandingkan ROIss pada KSS rongga mulut.

Background: The role of ADC values as an imaging biomarker in HNSCC has been extensively studied, but ADC values have not been routinely used to guide patient management due to the high heterogeneity of research findings. The method of ROI delineation is one of the factors that affect the measurement results of ADC values. The concordance of the single largest slice (ROIsls) and small sample (ROIss) methods compared to the whole volume (ROIwv) method in determining ADC values in oral HNSCC remain unknown. Methods: Measurements of mean and minimum ADC tumor values were conducted using ROIwv, ROIsls, and ROIss methods on 138 oral cavity HNSCC patients from January 2019 to September 2023, who met the study criteria. Normalized mean and minimum ADC tumor values relative to the mean and minimum ADC values of the spinal cord were also presented. Concordance of ADC measurement methods was analysed using correlation test. Results: The median mean ADC tumor values based on ROIwv, ROIsls, and ROIss were 1.210, 1.190, and 0.910 mm²/s, respectively. The median minimum ADC tumor values based on ROIwv, ROIsls, and ROIss were 0.730, 0.640, and 0.770 mm²/s, respectively. The mean ADC of ROIsls showed a strong positive correlation with the mean ADC of ROIwv (r = 0.846, p < 0.05). The minimum ADC of ROIsls showed a moderate positive correlation with the minimum ADC of ROIwv (r = 0.773, p < 0.05). There was a moderate positive correlation between the mean ADC of ROIss and ROIwv (r = 0.565, p < 0.05), as well as between the minimum ADC of ROIss and ROIwv (r = 0.767, p < 0.05). Normalizing tumor ADC parameters to spinal cord ADC parameters did not result in significant changes in the strength of the correlations. Conclusion: Measurement of ADC values based on the ROIsls method can be used as an alternative to ROIwv and is preferred over ROIss in oral HNSCC."

"Tongue squamous cell carcinoma, a relatively requent malignancy in the oral cavity has a great tendency to metastasize to regional lymph nodes that worsens the prognosis of the disease. The anti metastasis gene NM23, encodes a 17 KD cytoplasmic and nuclear proteins has shown controversy behaviour as metastatic suppressor in human cancer. An observational study using immunohistochemical staming method with LSAB (-) technique was conducted on 41 paraffin block specimens to show the relationship between significance of the expression of NM23 protein as a marker for cancer metastasis and the staging, cancer grading and the positive regional head and neck lymph nodes. Statistical significance of difference was evaluated using Chi square test (p<0.01). The result showed that there was an inverse relationship between expression of NM23 protein and the cancer grading as well as frequency of the positive regional head and neck lymph nodes supporting the role of NM23 as metastasis suppresor factor that may be useful for predicting tongue squamous cell carcinoma metastasis."
