    Abstract
    Introduction : Angiogenesis is a required process in the nutritional supply and oxygenation of tumor cells that possesses crucial role in the proliferation and metastatic spread of solid neoplasms. Angiogenesis can be assessed by Microvessel Density (MVD) via immunohistochemistry method. TNF-α has been reported acted as mediator in angiogenesis triggered by macrophages. TNF-α is able to induce the expression of proangiogenic molecules such as VEGF and its receptors, VEGFRs. Objective : To determine the correlation between the expressions of TNF-α and MVD in patients with nasopharyngeal carcinoma in H. Adam Malik General Hospital Medan. Methods : A cross-sectional study. 33 samples from patients with nasopharyngeal carcinoma were examined for the expressions of TNF-α and MVD via immunohistochemistry method. Results were analyzed by Spearman's test. Results : NPC most commonly occurs in males (69.70%), 41-60 years age group (57.58%) and non-keratinizing type of squamous cell carcinoma (54.55%). TNF-α positive expression mostly found in T3-T4 tumor size (59,30%), N2-N3 lymph node size around (70,40%) and clinical stage of III-IV (92,60%). Fisher's exact test showed no significant correlation either between the expression of TNF-α and primary tumor size (p=0.242), lymph node size (p=0.605) and clinical stage (p=0.142). Highly count MVD mostly found in T3-T4 tumor size (61,10%), N2-N3 lymph node size (72,20%) and clinical stage of III-IV (88,90%). There were no significant correlation between the expression of MVD and primary tumor size (p=0.316), lymph node size (p=0.512) and clinical stage (p=0.626). There is also no correlation between the expression of TNF-α and MVD (r=1,000; p=0,630). Conclusion : There is no correlation between the expression of TNF-α and MVD in nasopharyngeal carcinoma
     
    Pendahuluan : Angiogenesis adalah hal yang sangat dibutuhkan dalam nutrisi dan oksigenasi sel tumor. Hal ini penting untuk proliferasi dan penyebaran metastasis neoplasma padat. Angiogenesis dapat dinilai secara imunohistokima dengan Microvessel density (MVD). TNF-α telah dilaporkan dapat menjadi mediator pada angiogenesis yang dipicu oleh makrofag. TNF-α dapat menginduksi ekspresi molekul proangiogenik seperti VEGF dan reseptornya VEGFRs. Tujuan : Mengetahui korelasi ekspresi TNF-α dengan MVD pada penderita karsinoma nasofaring di RSUP H. Adam Malik Medan Metode : Penelitian ini penelitian analitik dengan studi potong lintang. Tiga puluh tiga sampel diperiksa secara imunohistokima untuk ekspresi TNF-α dan MVD. Kemudian hasil dianalisa dengan uji Spearman. Hasil Penelitian : Sebanyak 33 sampel KNF diperiksa ekspresi TNF-α dan MVD secara immunohistokimia. Penderita KNF paling banyak ditemukan pada laki-laki (69,70%), kelompok umur 41-60 tahun (57,58%) dan tipe non keratinizing squamous cell carcinoma (54,55%). Ekspresi TNF-α positif paling banyak ditemukan pada ukuran tumor T3-T4 (59,30%), ukuran kelenjar getah bening N2-3 (70,40%) dan stadium III-IV sebanyak (92,60%) dengan menggunakan Fisher’s exact test tidak ditemukan hubungan yang bermakna antara ekspresi TNF-α dengan ukuran tumor primer (p=0,242), ukuran kelenjar getah bening (p=0,605) dan stadium klinis (p=0,142). MVD tinggi paling banyak ditemukan pada ukuran tumor primer T3-T4 (61,10%), ukuran kelenjar getah bening N2-N3 (72,20%) dan stadium III-IV (88,90%), begitu juga MVD tidak ditemukan hubungan bermakna dengan ukuran tumor primer (p=0,316), ukuran kelenjar getah bening (p=0,512) dan stadium klinis (p=0,626) setelah dilakukan Fisher’s exact test. Tidak ditemukan adanya korelasi positif antara ekspresi TNF-α dengan MVD (r=1,000; p=0,630) Kesimpulan : Tidak ditemukan adanya korelasi antara ekspresi TNF-α dan MVD pada karsinoma nasofaring
