    Abstract
    BACKGROUND: In the H Adam Malik Hospital in Medan, IRK has been used as a method for screening before gynecological surgery to determine the possibility of ovarian neoplasms are benign or malignant, since done research on the IRK by Joshimin (2010). But the evaluation was conducted in some cases surgery found discrepancies between IRK presumption against malignancy with histopathology results. METHODS: Data from medical records of all patients who had surgery since the introduction of screening malignant ovarian neoplasms using IRK collected was evaluated by comparison test, determined characteristics, differences based on levels of ca 125, ultrasound and IRK3 with the old crossover point, then the sensitivity and specificity of IRK 3 and 4 newly determined based ttik new pieces. RESULTS: Of the total 384 cases were evaluated, acquired cases of benign ovarian tumors based on histopathology of 237 cases and 147 cases of malignant ovarian tumors. Based on the characteristics of the ovarian tumor patients, mostly in the age group 40-64 years (52.6%), had never given birth (42.2%), age of menarche is generally in the age group 12-16 years (92,9%), the highest histopathologic with the type of ovarian neoplasms benign adenoma musinosum are as many as 64 patients (27.12%) and malignant neoplasms that most are adenocarsinoma serosum much as 45 cases (30,61%). Based on the above chart, ROC, IRK3 having an area under the curve 0.802 which is relatively similar to the area under the curve of 0.808 IRK4. Based on the results of diagnostic tests, IRK3 had a sensitivity of 75.5% and a specificity of 73.9% at a cut off point 238.07 are also relatively similar to IRK4 which has a sensitivity of 73.5% and a specificity of 72.2% at a cut off point of 532,8. CONCLUSION: IRK 3 can still be used as a screening tool in ovarian neoplasms 238,07 cut off point, the sensitivity and specificity of 73,5% and 72.2. IRK 3 and 4 have the same relative specificity and sensitivity in differentiating benign and malignant ovarian neoplasms.
     
    LATAR BELAKANG: Di RS H Adam Malik Medan, telah digunakan IRK sebagai metode untuk penapisan sebelum operasi ginekologi untuk menentukan kemungkinan neoplasma ovarium tersebut jinak atau ganas, yakni sejak dilakukan penelitian tentang IRK oleh Joshimin (2010). Namun evaluasi yang dilakukan pada beberapa kasus operasi ditemukan ketidak sesuaian antara praduga IRK terhadap keganasan dengan hasil histopatologi. METODE PENELITIAN: Data rekam medik semua pasien yang telah dioperasi sejak diberlakukannya skrining keganasan neoplasma ovarium dengan menggunakan IRK dikumpulkan dievaluasi dengan uji komparasi, ditentukan karakteristik, perbedaan berdasarkan kadar ca 125, USG dan IRK3 dengan titik potong yang lama, selanjutnya sensitifitas dan spesifitas IRK 3 dan 4 yang baru ditentukan berdasarkan ttik potong yang baru. HASIL: Dari total 384 kasus yang dievaluasi, diperoleh kasus tumor ovarium jinak berdasarkan histopatologi sebanyak 237 kasus dan tumor ovarium ganas 147 kasus. Berdasarkan karakteristik pasien tumor ovarium, sebagian besar pada kelompok umur 40 – 64 tahun (52,6%), belum pernah melahirkan (42,2%), usia menarche umumnya pada kelompok umur 12 - 16 tahun (92,9%), secara histopatologi terbanyak dengan jenis neoplasma jinak adalah adenoma ovarii musinosum sebanyak 64 kasus (27,12%) dan neoplasma ganas yang terbanyak adalah adenocarsinoma serosum sebanyak 45 kasus (30,61%). Berdasarkan gambaran grafik ROC, IRK3 mempunyai area under the curve 0,802 yang relatif sama dengan area under the curve IRK4 sebesar 0,808. Berdasarkan hasil uji diagnostik, IRK3 mempunyai sensitivitas 75,5% dan spesifisitas 73,9% pada nilai cut off point 238,07 yang juga relatif sama dengan IRK4 yaitu mempunyai sensitifitas 73,5% dan spesifitas 72,2% pada nilai cut off point 532,8 KESIMPULAN: IRK 3 masih dapat dipakai sebagai alat skrining neoplasma ovarium dengan cut off point 238,07, sensitifitas 73,5 dan spesifitas 72,2. IRK 3 dan 4 memiliki spesifitas dan sensitifitas relatif sama dalam membedakan neoplasma ovarium jinak dan ganas.
