    Abstract
    LatarBelakang: Peradangan kronis diterima sebagai kondisi yang mendasari perkembangan tumor dan diperkirakan berkontribusi 20% dalam perkembangan kanker pada manusia, dimana etiologi kanker sangat kompleks dan sementara belum dapat dijelaskan, melibatkan faktor lingkungan eksternal dan genetik, Inflamasi memainkan peran penting dalam terjadinya onkogenesis. Tumor nekrosis faktor alpha (TNFα) merupakan sitokin proinflamsi utama dalam proses inflamasi. Polimorfisme pada gen -308 G/A TNFα berhubungan dengan tingkat protein yang diubah atau laju transkripsi, memodulasi respon inflamasi sehingga meningkatkan resiko kanker. Metode Penelitian: Penelitian ini adalah studi deskriptif melihat bagaimana gambaran polimorfisme gen -308 G/A TNFα pada 37 pasien kanker paru karsinoma bukan sel kecil. Pemeriksaan gen -308 G/A TNFα dengan teknik PCR-RFLP. Hasil penelitian ini diolah menggunakan SPSS 16.0 Hasil:Dari 37 pasien kanker paru didapati jenis kelamin laki-laki yang paling banyak dijumpai (62,2%), usia 50-59 tahun (43,2%), pekerjaan petani (56,8%), Jenis adenocarsinoma (89,1%) dan dengan stage IV (75,7%). Frekuensi genotipe gen -308 G/A TNFα adalah paling banyak GG 89,2%, GA 8,1%, dan AA 2,7%. Sedangkan frekuensi alel paling banyak didapati adalah alel G 93,2 diikuti alel A 6,8%. Kesimpulan:Distribusi terbanyak dijumpai adalah laki-laki, usia 50-59 tahun, pekerjaan petani, adenokarsinoma dan stage IV. Frekuensi terbanyak genotip gen -308 G/A TNFα adalah GG dan frekuensi alel terbanyak adalah alel G.
     
    Background: Chronic inflammation is accepted as a condition that underlies tumor development and is estimated to contribute 20% to the development of cancer in humans. The etiology of cancer is very complex and to date still can’t be explained, involving external environment and genetic factors. Inflammation plays an important role in oncogenesis tumor. Tumor necrosis factor alpha (TNFα) is a main pro-inflammatory cytokine in inflammation process. TNFα gene-308 G/A polymorphism can modulate the response of inflammation and cancer risk. Methods: This study is a descriptive study to determine the identification of TNFα gene-308 G/A polymorphism in 37 lung cancer patients in Haji Adam Malik Hospital Medan. TNFα gene-308 G/A polymorphismwas done with PCR-RFLP technique. The results of this study were processed using SPSS 16.0. Results: From the studies have shown that from 37 non small cell lung carsinoma patients the most common sex is male (62.2%), age 50-59 years (43.2%), farmer (56.8%), adenocarcinoma type (89.1%). ) and advanced stage (75.7%). The frequency of TNFα -308 G/A genotypes was GG 89.2%, GA 8.1%, and AA 2.7%. Meanwhile, the frequency of alleles was G 93.2% and allele A 6.8%. Conclusion: The most common TNFα -308 G/A genotypesand alleles were GG and alleles G, respectively.
