[ABSTRAK Kanker Nasofaring (KNF) salah satu pilihan terapinya adalahkemoterapi neoajuvan. Respon kemoterapi ini, di pengaruhi oleh Epidermal GrowthFactor Receptor(EGFR), faktor yang berperan pada pertumbuhan dan invasif tumor.Tujuan dari penelitian ini adalah untuk mengetahui perbandingan tingkat ekspresiEGFR dengan respon kemoterapi neoajuvan dan tingkat ekstensif tumor primer.Penelitian ini merupakan studi potong lintang deskriptif, dilakukan penilaian responkemoterapi neoajuvan dan tingkat ekstensif tumor primer, pada pasien KNF yang telahmendapat kemoterapi dan dilakukan pemeriksaan ekspresi EGFR. Hasil penelitian:Proporsi ekspresi EGFR pada kanker nasofaring untuk ekspresi negatif, positif dankuat, berturut-turut sebesar (10%), (70%) dan (20%). Pasien yang respon terhadapkemoterapi neoajuvan adalah 23 pasien (76,6%) dan tidak respon 7 pasien (23,4%).Kelompok pasien yang memberikan respon terhadap kemoterapi, 15 pasien ( 50%)memiliki intensitas EGFR yang lemah. Pasien dengan tingkat ekstensif T3-T4 ,mempunyai ekspresi EGFR lebih besar dibandingkan T1-T2 tumor.Kesimpulan : Proporsi ekspresi EGFR pada kanker nasofaring di Indonesia sebesar 90persen. Kemoterapi neoajuvan lebih respon pada tumor dengan ekspresi EGFR positifdan intensitas EGFR yang lemah. Tumor dengan tingkat ekstensif yang lebih tinggi,mempunyai ekspresi EGFR lebih tinggi. ABSTRACT Background: Neoadjuvan chemotherapy is one option of treatment for nasopharyngealcancer (NPC). The response of chemotherapy influenced by EGFR expression. EGFRis important factor for the growth and tumors invasion. Purpose of the study iscompare of the EGFR expression level with response of neoadjuvan chemotherapyand extensive level of the primary tumor. The methods is cross-sectional descriptivestudy that assessment of response to neoadjuvan chemotherapy and extensive level ofthe primary tumor. The NPC patients who have received chemotherapy is examinedof EGFR expression. Result of the study is the proportion of EGFR expression in NPCfor negative, positive and strong expression is 10%, 70%, and 20% respectively.Patients who responses to neoadjuvan chemotherapy are 23 patients(76.6%) andnon-responses 7 patients (23.4%). The group patients who responses to chemotherapy,15 patients (50%) have EGFR weak intensity. Patients with T3-T4 tumors (56,6%)have EGFR expression is greater than T1-T2 tumors(44,4%).Conclusion , The proportion of EGFR expression in NPC in Indonesia is 90 percent.Neoajuvan chemotherapy is more response in tumors with positive EGFR expressionand weak intensity. Tumors with high extensive levels have higher EGFRexpression.;Background: Neoadjuvan chemotherapy is one option of treatment for nasopharyngealcancer (NPC).
