    Abstract
    Background : Juvenile nasopharyngeal angiofibroma (JNA) is a benign vascular and locally invasive tumor that affects male adolescents. MMP has an important role in tumor invasion and angiogenesis. As a member of matrix metalloproteinase (MMPs), MMP-9 involved in extracellular matrix cleavage, was shown to be associated with tumor progression in several solid tumor. Objective : To determine the relationship between MMP-9 expression and clinical stage in patients with juvenile nasopharyngeal angiofibroma. Methods : An analytical study with cross-sectional study design, the number of samples was 27 patients with JNA who underwent immunohistochemical examination on JNA paraffin block. Result : MMP-9 overekspression was found in 18 male patient (69.2%), and 11 subjek range in15-18 years old. In stage II, MMP-9 overexpression was found in 5 subjek (55.6%), stage III 9 subjek (75%) and stage IV 4 subjek (80%). Conclusion : There were no signifikan association between clinical staging of the JNA with the MMP-9 expression.
     
    Latar Belakang : Angiofibroma nasofaring belia (ANB) adalah suatu tumor pembuluh darah jinak dan secara lokal invasif yang terdapat pada laki-laki dewasa muda. Matriks Metalloproteinase (MMP) memiliki peranan yang penting pada invasi tumor dan angiogenesis. Sebagai salah satu anggota dari matriks metalloproteinase, MMP-9 terlibat dalam kerusakan ekstraseluler matrik yang baisanya berhubungan dengan progresi tumor pada beberapa tumor padat. Tujuan : Melihat hubungan ekspresi MMP-9 terhadap stadium klinis pada pasien angiofibroma nasofaring belia. Metode : Penelitian analitik dengan rancangan studi potong lintang (crosssectional) dengan jumlah sampel sebanyak 27 pasien ANB yang telah dilakukan pemeriksaan pada blok parafin. Hasil : Overekspresi MMP-9 ditemukan pada 18 pasien laki-laki (69.2%) dan 11 subyek pada pasien dengan rentang umur antara 15-18 tahun. Pada stadium II overekspresi MMP-9 ditemukan sebanyak 5 subyek (55.6%), stadium III sebanyak 9 subyek (75%) dan stadium 4 sebanyak 4 subyek (80%). Kesimpulan : Tidak terdapat hubungan yang signifikan antara stadium klinis dengan ekspresi dari MMP-9.
