    Abstract
    Background : Nasopharyngeal Carcinoma (NPC) is a malignancy that tend to diagnosed at advanced stage with low survival and prognosis rate. One of the factor that may play a role in progresivity and metastasis of tumour is overexpression of vascular endothelial growth factor (VEGF) which is a key role in tumour angiogenesis. The aim of this study is to learn the expression of VEGF in NPC, and to learn the association of VEGF expression with tumour stage and histopathologic type of NPC. Study design and methods : This is a cross sectional study performed in ENT-HNS Department of Medical School of University of North Sumatera / H. Adam Malik Hospital. Sample was collected by non probability consecutive sampling, starting from March 2008. NPC patients underwent histophatologic examination and immunohistochemical analysis from nasopharyngeal biopsy. VEGF expression analysed by red-brown stained cytoplasm. Data was analysed by Spearman’s correlation test and chi square test. Results : VEGF positive expression was found in 21 of 28 (75.0%) NPC cases. VEGF overexpression was found in 10 of 28 (35.7%) NPC cases. No significance correlation found between tumour stage and VEGF expression (p > 0.05). No significance association found between histophatologic type and VEGF expression (p > 0.05). Conclusions : VEGF expression is relatively high in NPC patient. VEGF may play a role in the angiogenesis of NPC.
     
    Latar Belakang : Karsinoma Nasofaring (KNF) adalah tumor ganas yang cenderung didiagnosa pada stadium lanjut, sehingga angka survival rendah dan prognosis penderita jelek. Salah satu faktor yang diduga berperan dalam progresivitas tumor dan metastase tumor adalah overekspresi vascular endothelial growth factor (VEGF) yang berperan penting dalam proses angiogenesis tumor. Penelitian ini dilakukan untuk melihat ekspresi VEGF pada KNF, serta melihat hubungan ekspresi VEGF dengan stadium dan jenis histopatologi KNF. Metode Penelitian : Penelitian dilakukan dengan studi potong lintang (cross sectional study) di Departemen THT-KL FK USU / RSUP H. Adam Malik Medan, secara non probability consecutive sampling mulai Maret 2008. Terhadap penderita KNF dilakukan pemeriksaan histopatologi dan imunohistokimia dari jaringan nasofaring yang diperoleh dari biopsi. Ekspresi VEGF dinilai pada sitoplasma yang terwarnai merah kecoklatan . Data dianalisa dengan uji korelasi Spearman dan uji chi square dengan batas kebermaknaan p < 0,05. Hasil Penelitian : Sebanyak 21 dari 28 kasus KNF (75,0%) memiliki ekspresi VEGF positif. Overekspresi VEGF dijumpai pada 10 dari 28 kasus KNF (35,7%). Tidak dijumpai korelasi yang bermakna antara stadium tumor dengan ekspresi VEGF pada KNF (p > 0,05). Tidak dijumpai hubungan yang bermakna antara jenis histopatologi dengan ekspresi VEGF pada KNF (p > 0,05) Kesimpulan : Ekspresi VEGF cukup tinggi pada penderita KNF. Kemungkinan VEGF berperan dalam proses angiogenesis pada KNF.
