Background: Serous and mucinous tumors are 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. Actually IFN-γ treatment is a double-edged sword whose anti- and protumorigenic activities are dependent on the cellular, microenvironment, and/or molecular context. The cytokines IL-4 acts as an anti-apoptotic. The purpose of this study is 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 descriptive analytic assesment with cross-sectional approach in 40 samples of benign and malignant serous and mucinous tumors. Immunohistochemistry with IFN - γ and IL - 4 were performed in each tumors (n=10). Results: In this study the expression of IL-4 was positive in 60% ( n=6) and negative in 40% (n=4) in the benign serous tumors, whereas in the malignant serous tumors was positive in 90% (n=9) and negative in 10% (n=1). In the benign mucinous tumors the expression of IL-4 was positive in 40%(n=4) and negative in 60% (n= 6), whereas in the malignant mucinous tumors was entirely positive (100%). Expression of IFN-γ was positive in 50% (n=5) and negative in 50% (n=5) in the benign serous tumors, whereas in the malignant serous tumors was positive in 40%(n=4) and negative in 60%(n=6). In the benign mucinous tumors the expression of IFN-γ was positive in 60%(n=6) and negative in 40%(n=4), whereas the malignant mucinous tumors was positive in 80%(n=80) and negative in 20%(n=2). Conclusion: There is a difference expression of IFN-γ and IL-4 in benign and malignant serous and mucinous epithelial ovarian tumors. Latar Belakang: Tumor serosum dan musinosum merupakan varian dari tumor epitel ovarium. IFN-γ hubungannya dengan tumor mempunyai aktifitas anti proliferasi tetapi pada keadaan tertentu IFN-γ mempunyai efek anti apoptosis terhadap sel tumor ovarium manusia. Sebenarnya terapi IFN-γ seperti pedang bermata dua yang mempunyai aktifitas anti dan protumorigenic, tergantung pada keadaan selular, lingkungan mikro, dan / atau 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 epitel ovarium tipe serosum dan musinosum. Metode: Penelitian ini merupakan penelitian deskriptif analitik dengan pendekatan cross sectional pada 40 sampel jaringan tumor jinak dan ganas serosum dan musinosum, kemudian dilakukan pemeriksaan imunohistokimia dengan antibodi IFN-γ dan IL-4 pada masing-masing tumor (n=10). Hasil: Pada penelitian ini IL-4 menunjukkan ekspresi positif sebanyak 60% (n=6) dan negatif 40% (n=4) pada tumor jinak serosum, sedangkan pada tumor ganas serosum menunjukkan ekspresi positif 90% (n=9) dan negatif 10% (n=1). Pada tumor jinak musinosum IL-4 menunjukkan ekspresi positif 40% (n=4) dan negatif 60% (n=6), sedangkan pada tumor ganas musinosum seluruhnya menunjukkan ekspresi positif (100%). IFN-γ menunjukkan ekspresi positif sebanyak 50% (n=5) dan negatif 50% (n=5) pada tumor jinak serosum, sedangkan tumor ganas serosum menunjukkan ekspresi positif 40% (n=4) dan negatif 60% (n=6). Pada tumor jinak musinosum IFN-γ menunjukkan ekspresi positif 60% (n=6) dan negatif 40% (n=4), sedangkan pada tumor ganas musinosum menunjukkan ekspresi positif 80% (n=80) dan negatif 20% (n=2). Kesimpulan: Terdapat perbedaan ekspresi IFN-γ dan IL-4 pada tumor jinak dan ganas epitel ovarium serosum dan musinosum.
