Abstract
Amaç: Bu çalışmadaki amaç over tümörlerindeki frozen
tan›lar›n›n do¤rulu¤unu retrospektif olarak de¤erlendirmektir.
Metod: Over tümörü nedeniyle cerrahi ve frozen kesit
yap›lan hastalar retrospektif olarak de¤erlendirildi. Frozen
ve kal›c› tan›lar üç gruba ayr›ld› (benign, borderline ve malign)
ve tümörler çaplar›na göre s›n›fland›r›ld› (<10cm, 10-
20 cm ve >20 cm). Her frozen tan›s› için do¤ruluk oran›,
sensitivite, spesifite, pozitif ve negatif prediktif de¤erler hesapland›.
Bulgular: Ocak 2001- Ekim 2004 tarihleri aras›nda frozen
yap›lan 105 over tümörü incelendi. Kesin parafin tan›-
lar› %63 benign, %4 borderline, %33 malign idi. Malignite
potansiyellerine göre frozen tan›lar› parafin tan›lar› ile tüm
vakalar›n %93,3’ünde do¤ruland›. Malign tümörler için frozen
sensitivitesi %93, spesifitesi %98, borderline tümörler
için bu de¤erler s›ras›yla %60 ve 96, benign tümörlerde ise
s›ras›yla %96 ve 94 idi. Çap› <10 cm olan tümörler için do¤-
ruluk oran› 10-20 cm ve >20cm olanlara göre daha yüksek
idi (s›ras›yla %96, %86 ve %92).
Sonuç: ‹ntraoperatif frozen konsültasyonu malign ve
benign over tümörleri için yüksek sensitivitesi nedeniyle
güvenilir bir yöntemdir. Ancak frozen do¤ruluk oran› borderline
ve çap› >10 cm olan tümörlerde düşüktür

Abstract
Objective: The goal of this work was to evaluate retrospectively, the accuracy of frozen section diagnosis in ovarian tumors.Method: Retrospective study of frozen sections performed in patients with ovarian tumors who underwent surgery. Frozen and paraffin sections were divided into three categories (benign, borderline and malignant) and stratified by diameter (20 cm). The diagnostic correlation, sensitivity, spesificity, positive and negative predictive values and accuracy of each frozen section diagnosis were determined. Results: One hundred five ovarian tumors that underwent frozen sections between January 2001 and October 2004 were studied. Permanent paraffin diagnosis was 63% benign, 4% borderline and 33% malignant. As for malignant potential, frozen section diagnosis agreed with paraffin diagnosis in 93,3% of all cases. Sensitivity and specificity for malignant tumors were 93 and 98%, for borderline tumors 60 and 96%, and for benign tumors 96 and 94%, respectively. The accuracy rate was higher in ovarian tumors with a diameter < 10 cm than 10 - 20 cm and >20 cm (96, 86 ve 92%, respectively). Conclusion: Intraoperative frozen section consultation for malignant and benign ovarian tumors is a reliable method due to a high sensitivity rate. On the other hand its sensitivity decreases in borderline cases and tumors with a diameter > 10 cm.
