Ruang lingkup dan cara penelitian: Karsinoma ovarium merupakan salah satu keganasan yang sangat penting karena menempati urutan ke empat penyebab kematian pada wanita. Di Indonesia dari tahun 1989-1992 terdapat 13% karsinoma ovarium dalam 1.726 kasus. Diagnosis histopatologik memegang peranan penting dalam penanganan tumor ovarium. Saat ini yang masih sering menimbulkan masalah diagnostik adalah membedakan antara tumor borderline dengan kistadenokarsinoma padahal penanganan dan prognostiknya berbeda. AgNOR merupakan salah satu cara penilaian proliferasi dengan menghitung nucleolar organizer region (NOR) yang merupakan lengkung DNA ribosom yang ditranskripsikan menjadi RNA ribosomal dengan bantuan RNA polimerase. Jumlah dan ukuran AgNOR berkorelasi dengan aktivitas proliferasi sel. Peningkatan nilai AgNOR mencerminkan peningkatan aktivitas proliferasi sel atau ploidi. Pada penelitian ini, nilai AgNOR digunakan untuk melihat hubungannya dengan derajat histopatologik tumor ovarium musinosum. Penghitungan nilai AgNOR dilakukan pada 20 kasus kistadenoma, 20 kasus tumor borderline dan pada 20 kasus kistadenokarsinoma dengan dua cara, yaitu rata-rata jumlah AgNOR per nukleus (mAgNOR) dan persentase nukleus dengan AgNOR>1, >2, >3 dan >4 (pAgNOR). Hasil dan kesimpulan: Dari penelitian ini diperoleh nilai mAgNOR dan pAgNOR meningkat dan kistadenoma, tumor borderline dan kistadenokarsinoma (masing-masing 2,14; 3,55 dan 5,18). Nilai pAgNOR pada karsinoma lebih tinggi daripada nilai pAgNOR pada kistadenoma dan pada tumor borderline (pAgNOR>1 pada kistadenoma 69,55%; pada tumor borderline 964% dan pada kistadenokarsinoma 99,95%). Dengan menggunakan analisis varian didapatkan perbedaan bermakna di antara ke tiga jenis tumor tersebut (p=0,00). Dan dengan uji korelasi diperoleh hubungan yang sangat kuat antara nilai AgNOR dan derajat histopatologik tumor ovarium musinosum. Hasil ini menunjukkan bahwa nilai AgNOR dapat digunakan untuk membedakan antara kistadenoma ovarium musinosum, tumor borderline dan kistadenokarsinoma. ......Ovarian carcinomas are one of the most important malignant tumors because it had become the fourth most common cause of female cancer death. In Indonesia from 1989 to 1992, more than 13 % of 1.726 cancer cases were ovarian carcinomas. Histopathologic diagnostic become an important role in treatment of ovarian tumors. However, the main problem in histopathologic diagnostic the difficulties in differentiating ovarian cystadenocarsinomas and borderline tumors. Application of objective method is therefore necessary for the differential diagnosis. Nucleolar organizer region (NOR) are loops of DNA on the short arms of acrocentric chromosomes that presumably are associated with ribosomal RNA activity, protein synthesis and cellular proliferation. NOR are readily demonstrated by means of argyrophilia of their associated proteins, using the so-called AgNOR technique. Increased number of AgNOR may reflect increased proliferative activity of cell or ploidy, i.e., the count of AgNOR per nudeus was higher in malignant than in benign tissues. In this study, the authors tested AgNOR counting method for their ability to discriminate between benign tumour, borderline tumor and carcinoma and to see correlation between histopathologic grades of mutinous ovarian tumors with AgNOR counts. Selective cases of 20 cases cystadenomas, 20 cases of borderline tumors and 20 cases of cystadenocarsinomas were evaluated by 2 AgNOR counting method: 1) the mean number of AgNORs per nucleus (mAgNOR) and 2) the percentages of nuclei with >1, >2, >3 and >4 AgNORs (pAgNOR>1, pAgNOR>2, pAgNOR>3 and pAgNOR>4, respectively). Result and conclusion: mAgNOR counts demonstrated a progressive increase from cytadenomas to borderline tumours and to cystadenocarcinomas (2,14; 3,55 and 5,18, respectively). pAgNOR counts were higher in carcinoma than in cystadenoma and in borderline tumors (in adenoma, 69.55% have pAgNOR>1, while in borderline and in carcinoma were 96,1% and 99,55%, respectively). Using analysis of variance, both AgNOR counts enabled significant discrimination between cystadenoma, borderline tumours and carcinoma (13=0, 00). The AgNOR counts show statistically significant correlation with histopathological grade of mucinous ovarian tumors. The result indicates that the AgNOR counting procedure may be useful in distinguishing borderline tumours from cytadenocarcinoma and cystadenoma mutinous of ovary.

Latar belakang: Angka ketahanan hidup 5 tahun pasien keganasan ovarium rendah, karena >70% kasus terlambat didiagnosis. Skor Gatot Purwoto merupakan metode prediksi keganasan ovarium pra-bedah. Terdapat rentang yang berbeda cukup jauh antara nilai diagnostik Gatot Purnomo dari beberapa penelitian. Pada aplikasinya penderita tumor ovarium curiga ganas dengan skor prediksi Gatot Purwoto (GP) < 4 (rendah) masih terdapat kecurigaan adanya keganasan ovarium sehingga masih dilakukan prosedur potong beku sebagai alat diagnostik intrabedah. Tujuan: Untuk mengetahui sensitivitas, spesifisitas, nilai duga positif dan nilai duga negatif prosedur potong beku yang dilakukan pada penderita tumor ovarium curiga ganas dengan skor prediksi Gatot Purwoto ≤ 4 dan untuk mengetahui peningkatan nilai diagnostik antara prosedur potong beku dibandingkan dengan skor gatot purwoto pada penderita tumor ovarium curiga ganas dengan skor prediksi Gatot Purwoto ≤ 4 Metode: Uji ini adalah uji diagnostik dengan desain potong lintang. Pasien tumor ovarium curiga ganas dengan skor prediksi Gatot Purwoto (GP) < 4 yang dilakukan prosedur potong beku di RSCM selama periode Juli 2008 – Juli 2013 diikutsertakan dalam penelitian ini. Data diambil secara konsekutif dari rekam medik, kemudian dianalisis secara manual dengan menggunakan tabel 2x2 dan rumus parameter diagnostik. Kami menganalisis nilai diagnostik potong beku dibandingkan dengan baku emas yaitu blok parafin. Kemudian kami melihat adakah peningkatan nilai diagnostik prediksi keganasan ovarium jika hanya dilakukan skor GP saja dan jika dilakukan skor GP disertai dengan potong beku Hasil: Dari 160 orang subyek penelitian didapatkan prosedur potong beku memiliki akurasi yang cukup baik dalam mendiagnosis keganasan ovarium yaitu 78,5%. Sensitivitas, spesifisitas, nilai duga positif, nilai duga negatif dan akurasi prosedur potong beku pada penelitian ini berturut turut adalah 84,3%, 92,9%, 75%, 95,9% dan 85,5%. Selain itu prosedur potong beku pada penderita tumor ovarium curiga ganas dengan skor prediksi GP ≤4 secara bermakna memberikan manfaat dalam mendiagnosis keganasan ovarium yaitu meningkatkan nilai diagnostik sebesar 15,9% dibandingkan hanya menggunakan skor GP saja tanpa potong beku. Kesimpulan: Prosedur potong beku memiliki nilai diagnostik yang baik dan masih memberikan manfaat dalam mendiagnosis tumor ovarium curiga ganas dengan skor prediksi GP < 4. Skor prediksi GP memberikan nilai diagnostik yang cukup rendah untuk memprediksi keganasan ovarium, sehingga perlu dilakukan perbaikan sistem penilaian prediksi keganasan ovarium. ......Background: The 5-year survival rate of patients with ovarian cancer is low, because over 70% of cases are diagnosed in a late stage. Gatot Purwoto score is a method to predict ovarian malignancy prior to surgery. There is a variabel range on the diagnostic values of Gatot Purwoto (GP) score from several studies. In its application, patients with GP prediction score < 4 (low) still has a suspicion for ovarian malignancy, therefore frozen section is still performed as an intraoperative diagnostik tool. Aim: To obtain the sensitivity, specificity, positive predictive value, and negative predictive value of frozen section performed in patients with suspected malignant ovarian tumors with GP score ≤ 4 and to discover the increase of diagnotic value of frozen section compared to GP score in patients with suspected malignant ovarian tumors with GP score ≤ 4. Methods: This is a diagnostic study with cross sectional design. Patients with suspected malignant ovarian tumors with GP score ≤ 4 who underwent frozen section in RSCM from July 2008 – July 2013 were included in this study. Data were obtained consecutively from medical records, then analyzed manually with 2x2 tables and diagnostik parameter formula. We analyzed frozen section compared to the gold standard (paraffin block). Then we observed if there was an increase of diagnostic value of predicting ovarian malignancy with GP score alone or GP score combined with frozen section. Result: We obtained 160 subjects. Frozen section had an overall good accuracy in predicting ovarian malignancy (78.5). The sensitivity, specificity, positive predictive value, and negative predictive value of frozen section are 84,3%, 92,9%, 75%, 95,9% and 85,5%, respectively. Frozen section also increased the diagnostic value as much as 15,9% compared to GP score alone without frozen section. Conclusion: Frozen section had a good diagnostic value and is still useful in diagnosing suspected malignant ovarian tumors with GP score ≤ 4. GP prediction score has a quite low diagnostic value in predicting ovarian malignancy, therefore an improved system to predict ovarian malignancy is needed.

ABSTRACT
B cell leukemia lymphoma 2 Bcl 2 and Bcl 2 associated X protein Bax are members of the Bcl 2 family that play a role regulating apoptosis. Apoptosis plays an important role in human development. Disruption of apoptosis will have an effect on the physiological state of humans, including reproductive disorders. One of there productive disorders experienced by women in reproductive age is Polycystic Ovary Syndrome (PCOS). Women with PCOS have a higher number of follicles than women without PCOS. The aim of this study was to find out the expression of baxand bcl 2 mRNA expression in PCOS women and to know the correlation of bax mRNA expression ratio to bcl 2 with fertilization ratio. Granulosa cells for the study were obtained from 18 women with PCOS and 10 women without PCOS undergoing IVF program. The results showed no significant difference between the expression ratio of bax bcl 2 mRNA women with PCOS and without PCOS p 0.05. A strong correlation R 0.525 was found between the expression ratio of bax bcl 2and the fertilization rate.
