<![CDATA[ABSTRAK Latar belakang Tumor serosum dan musinosum merupakan jenis tumor epitelial ovarium. IFN-γ berhubungan dengan tumor epitelial ovarium melalui aktivitas anti proliferasi, walaupun pada keadaan tertentu IFN- γ mempunyai efek apoptosis terhadap sel tumor ovarium manusia. Terapi IFN-γ mempunyai aktivitas anti dan protumor, tergantung pada keadaan selular, lingkungan mikro, dan konteks molekul. Sitokin IL-4 berperan sebagai anti apoptosis. Tujuan penelitian ini adalah melihat perbedaan ekspresi IFN-γ dan IL-4 pada tumor jinak dan ganas epitelial ovarium tipe serosum dan musinosum. Metode Penelitian ini merupakan penelitian observasional analitik dengan pendekatan potong lintang dari 40 sampel jaringan tumor jinak dan ganas serosum dan musinosum dengan jumlah yang sama. Dilakukan pemeriksaan imunohistokimia dengan antibodi IFN-γ dan IL-4. Hasil Pada penelitian ini IL-4 menunjukkan ekspresi positif sebanyak 60% (n=6) dan pada tumor jinak serosum, sedangkan pada tumor ganas serosum ekspresi positif 90% (n=9). Pada tumor jinak musinosum IL-4 menunjukkan ekspresi positif 40% (n=4), sedangkan pada tumor ganas musinosum seluruhnya menunjukkan ekspresi positif (100%). IFN-γ menunjukkan ekspresi positif sebanyak 50% (n=5) pada tumor jinak serosum, sedangkan tumor ganas serosum menunjukkan ekspresi positif 40% (n=4). Pada tumor jinak musinosum IFN-γ menunjukkan ekspresi positif 60% (n=6), sedangkan pada tumor ganas musinosum menunjukkan ekspresi positif 80% (n=80). Kesimpulan Tidak terdapat perbedaan bermakna ekspresi IFN-γ dan IL-4 pada tumor jinak dan ganas serosum dan musinosum. Kata kunci : imunohistokimia, tumor epitelial ovarium, tumor musinosum ovarium, tumor serosum ovarium. ABSTRACT Background Serous and mucinous tumors were variant of epithelial ovarian tumors. IFN-γ associated with anti-proliferative activity of the tumor, but in the spesific situation IFN-γ has anti apoptosis effect against the ovarian tumor cells. IFN-γ treatment was protumorigenic and anti tumorigenic activities were dependent on the cellular, microenvironment, and/or molecular context. The cytokines IL-4 acts as an anti-apoptotic. The purpose of this study was to view the difference expression of IFN-γ and IL-4 in benign and malignant serous and mucinous epithelial ovarian tumors. Methods This study is a observational analytic assesment with cross-sectional approach in 40 samples of benign and malignant serous and mucinous tumors. Immunohistochemistry with IFN-γ and IL-4. Results In this study the expression of IL-4 was positive in 60% (n=6) in the benign serous tumors, whereas in the malignant serous tumors was positive in 90% (n=9). In the benign mucinous tumors the expression of IL-4 was positive in 40% (n=4), whereas in the malignant mucinous tumors was entirely positive (100%). Expression of IFN-γ was positive in 50% (n=5) in the benign serous tumors, whereas in the malignant serous tumors was positive in 40% (n=4). In the benign mucinous tumors the expression of IFN-γ was positive in 60% (n=6), whereas the malignant mucinous tumors was positive in 80% (n=80). Conclusion There was not difference expression of IFN-γ and IL-4 in benign and malignant serous and mucinous tumors. Key words: epithelial ovarian tumor, immunohistochemistry, mucinous tumor, serous tumor.]]>
