ABSTRACTBiomarkers to predict locoregional lymph nodes metastasis is not yet accurate untilnow. The number of occult metastasis in laryngeal carcinoma varies between 165%.A tumor biomarker that can give information on the existence of locoregional lymphnode involvement in patients with or without signs of clinical locoregional lymph nodeinvolvement, as guidelines whether selective neck dissection is needed in N0 cases. Forpatients that need additional treatment biomarkers that are correlated with aggresivityand metastasis prediction such as EGFR, MMP-9, TIMP-1, VGEF, E-cadherin, collagenType IV and HPV are also needed to predict the outcome of patients with or withoutlymph node metastasis.This study aimed to investigate the evidence of HPV infection in laryngeal carcinomaand the role of biomarkers EGFR, MMP-9, TIMP-1, VEGF, E-cadherin and collagentype IV, in a late stadium laryngeal SCC observed clinically, especially in N0 and alsoto predict diagnosis of a locoregional lymph node that has potential for metastasis.Cross-sectional, double blind study with planned data collection was performed in theDepartment of ENT FKUI-RSCM. Data were taken from Formalin Fixed ParaffinEmbedded (FFPE) of laryngeal cancer specimen after laryngectomies. Samples wereanalysed by nested Polymerase Chain Reaction (PCR) and continuous flow-throughhybridizationed for genotyping. Expression of EGFR, MMP-9, TIMP-1, VEGF, Ecadherin,and collagen Type IV as metastasis biomarker were evaluated byimmunohistochemistry.Overall HPV proportion in laryngeal cancer was 28.7%. A total of 9,15% laryngealcancer patients were infected with high risk HPV type and HPV 16 was the mostfrequently observed. Mantel-Haenszel multivariate analysis found that HPV infection didnot play role in neck metastasis eventhough there were positive evidence of metastasisbiomarker. In contrast, the absent of HPV infection, positif metastasis biomarker of EGFRand VEGF have risk for neck nodes metastasis with OR 3.38; 5.14 fold consecutively.The algorithm was formed from the PM model to determine the metastasis potential tolocoregional lymph nodes of late stadium laryngeal SCC with N0.HPV was found to be the oncogenic factor of the laryngeal SCC and HPV 16 was themost frequently observed type in laryngeal SCC.

Background: Squamous cell carcinoma (SCC) of the tongue is the most common oral cavity cancer. Neck dissection was done simultaneously with wide excision of the tumor because of occult metastases high rate (about 30%) in clinically non-palpable neck lymph nodes (N0). Based on previous research, the epithelial marker E-cadherin and cancer stem cell marker CD44 could be used as pre-surgical diagnostic tools to identify patients who have lymph node metastases so that it could be a modality that helps surgeons in making decisions about neck dissection type to be performed to provide the best benefit for patients. Objective: To evaluate the association between E-cadherin and CD44 expressions and neck lymph node metastasis in SCC of the tongue. Methods: This research was an analytical study with a cross-sectional design. Samples were taken through consecutive sampling according to inclusion and exclusion criteria. Inclusion criteria were patients with SCC of the tongue without distant metastases, post wide excision of the tumor with neck lymph node dissection, and eligible paraffin block for examination. Sociodemographic and clinicopathological data were obtained from medical records. Immunohistochemistry staining was performed with E-cadherin and CD44 from stored paraffin blocks, then the expression levels of E-cadherin and CD44 were grouped into high and low according to the literature. Statistical analysis was conducted with SPSS 24.0. Results: Thirty samples of SCC of tongue were collected, consist of 15 subject with neck lymph node metastasis tongue and 15 subject without neck lymph node metastasis. From data analysis, a significant difference was found between E-cadherin and CD44 expressions with neck lymph node metastasis (p value was 0.000 and 0.003, respectively). Conclusion: Low expression of E-cadherin and high expression of CD44 was significantly associated with the occurence of neck lymph node metastasis in SCC of the tongue."

Background: Breast cancer is the most common type of cancer in women and the most common cause of cancer death. Lymph node status (KGB) is a prognostic factor and determinant of treatment options for breast cancer patients. The biomarker for predicting lymph node metastasis is not accurate until this time. Several biomarkers associated with aggressiveness and metastatic prediction are CD44 (Cluster of Differentiation44) and MT1-MMP (Membrane Type 1-Matrix Mettaloproteinase). The high expression of CD44 and MT1-MMP is associated with a more aggressive nature and poor prognosis. The tumor biomarkers are needed to provide information on the presence of lymph node metastases.

Aims: This study aims to determine the relationship between CD44 and MT1-MMP expression on lymph node metastases of invasive breast cancer NST.

Method: An observational analytic study with a cross-sectional design on a mastectomy operation for invasive breast carcinoma NST cases at RSCM from January 2019 to June 2020. The study sample was divided into 2 groups, 24 cases of NST invasive breast carcinoma with lymph node metastases and 24 cases of invasive breast carcinoma NST without lymph node metastases. The research sample was taken by simple random sampling of cases that met the inclusion criteria and did not include the exclusion criteria. CD44 and MT1-MMP immunohistochemical staining were performed and the number of cells stained positively was calculated. Chi-Square and Kruskal Wallis statistical analysis was performed between the two groups.

Results: There was a significant difference in the expression of CD44 in invasive breast carcinoma NST with and without lymph node metastases (p = 0.009). There was a significant difference in the expression of MT1-MMP in invasive carcinoma of No Special Type breast carcinoma with and without lymph node metastases (p = 0.032). And there is a relationship between CD44 and MT1-MMP overexpression in lymph node metastases (p = 0.000)

Conclusion: There was a significant relationship between CD44 and MT1-MMP expression in invasive breast carcinoma NST and lymph node metastasis status."

Background and Objective CT scan is the main imaging modality in various head and neck primary tumors and broader availability in Indonesia. This study aims to discuss CT as a modality that helps establish the diagnosis of lymph node metastases so the management of head and neck squamous cell carcinoma HNSCC can be done with the best therapeutic value and prognosis. This study of Choi modification is trying to research about association between diagnostic criteria of metastases lymph node in CT Scan and histopathologic in SCC Patients Methods This research is a cross sectional associative study on the primary data of the new case of HNSCC. Data collection took place from February 2018 to April 2018 at the Polyclinic Oncology Department of ENT, Department of Radiology and Department of Pathology Anatomy Cipto Mangunkusumo Hospital. A total of 90 sample units were evaluated for location, morphology and possible metastasis on preoperative CT scans using diagnostic criteria, then each sample unit was labeled to support node per node association which was then adjusted to intraoperative lymph node findings. Neck dissection surgery is performed less than 1 week after a preoperative CT scan. After the operation, every lymph node that has been labeled is carried out to histopathologic examination. Then the hypothesis of association of the findings on preoperative CT scans and histopathologic is tested using McNemar test. Results This study shows p value 0,000 so that there is a significant difference between the diagnostic criteria on CT scan and histopathologic examination. Assessment of the diagnostic criteria for malignant KGB on CT scans and histopathologic examination using Kappa obtained R 0.12 p 0.100 , which shows no suitability between them. The diagnostic criteria for malignant lymph node on CT scan in this study have a sensitivity value of 33.3 and a specificity value of 61.7 with a specificity value of the size of the short axis, hypodensity and heterogeneous enhancement respectively 100 and the sensitivity value of the primary drainage site 100 . Conclusion There is no agreement between the diagnostic criteria for malignant lymph nodes on CT scan with histopathologic examination. The existence of a highly sensitive but non specific and a highly specific but insensitive component of the diagnostic criteria might causes the sensitivity and specificity of these diagnostic criteria to be low."

Vascular Endotbelia1 Growth Factor (VEGF) is a chimeric glycoprotein produced by tumor cells and tissues that require ample blood supply. Some studies have suggested that there is an association between metastasis of cancer cells to the axillary lymph nodes and VEGF C and D especially in ductile invasive breast carcinoma. The over expression from VEGF together with HER-2 were found in 77.2 percent of breast cancer patients. Furthermore evidence suggest that VEGF expression is connected with the spread of cancer to the axillary lymph nodes. We examined breast cancer stage II with HER-2 positive, as the spread of cancer cells to the axillary lymph nodes from the same breast cancer side will only be found at stage H for both tumor under 2 em or more than 2 em. We examined VEGFC the its relationship with axillary lymph node. The results from this research is aimed at monitoring the spread of breast cancer to the axillary lymph nodes and to predict its spread and therefore to find the most effective treatment management for this type of cancer. We analyzed VEGF-C expression in 95 sample breast cancer stage ll with HER-2 positive from 1999 2009. There is no significant associated between VEGF-C expression and axillary lymph node (p = 0.089)."

"Menilai tingkat akurasi Node-RADS dalam mendiagnosis metastasis kelenjar getah bening regio leher pada pasien dengan karsinoma sel skuamosa di kepala dan leher.

Metode: Sebanyak 221 sampel kelenjar getah bening dari 40 pasien yang memenuhi kriteria penelitian studi potong lintang yang menjalankan pemeriksaan CT scan leher dengan kontras, dilakukan operasi diseksi leher, dan memiliki hasil pemeriksaan histopatologi dari tahun 2020 hingga 2023. Dilakukan analisis bivariat antara Node-RADS dan histopatologi menggunakan Mc Nemar test dan Kappa Cohen R.

Hasil: Sistem skoring Node-RADS memiliki nilai diagnostik yang tidak terlalu berbeda dengan histopatologi dengan p = 0,76. Sistem skoring Node-RADS memiliki nilai Kappa Cohen 0,725, masuk kedalam substansial agreement. Hasil rasio konkordans pada skoring Node-RADS yang tinggi sebesar 88,2%, Sensitivitas 87,3%, Spesifisitas 88,6%, Nilai Duga Positif 75,3%, Nilai Duga Negatif 94,5%, LR+ 7,2, LR- 14%.

Kesimpulan: Node-RADS memiliki nilai akurasi yang cukup tinggi dan dapat dipertimbangkan sebagai metode diagnostik metastasis kelenjar getah bening regio leher pada pasien dengan karsinoma sel skuamosa di kepala dan leher.

Squamous cell carcinoma is generally associated with metastases to the lymph nodes of the cervical region. Ricently,there have been attemts to standardize radiology reporting in oncology cases with the adoption of the Reporting and Data Systems (RADS). Node-RADS 1.0 aims to improve reporting of regional and distant lymph nodes in cancer patients by providing imaging criteria for size and configuration, facilitating a standardization system in reporting lymph nodes. However, there have been no reports regarding the suitability of Node-RADS in head and neck squamous cell carcinoma patients.

Objective: Assessing the accuracy of Node-RADS in diagnosing lymph node metastases in the neck region in patients with squamous cell carcinoma of the head and neck.

Method: A total of 221 lymph node from 40 patients who met the criteria for a cross-sectional research study, underwent a CT scan of the neck with contrast, neck dissection surgery, and had histopathological examination results from 2020 to 2023. Bivariate analysis was carried out between Node-RADS and histopathology using the McNemar test and Cohen's Kappa (κ).

Results: Node-RADS scoring system had a diagnostic value that was not significantly different from histopathology, with p = 0.76. The Node-RADS scoring system has a Cohen's Kappa value of 0.725, indicating substantial agreement. The concordance ratio results for Node-RADS scoring were high, with 88.2% concordance, a sensitivity of 87.3%, specificity of 88.6%, positive predictive value of 75.3%, negative predictive value of 94.5%, LR+ of 7.2, and LR- of 14%.

Conclusion: Node-RADS has a high accuracy value and can be considered as a diagnostic method for lymph node metastases in the neck region in patients with squamous cell carcinoma of the head and neck."
