Abstract

Aim: Endometrial cancer is the most common gynecological malignancies in developed countries. Total hysterectomy with bilateral salpingoophorectomy is the standard treatment for early stage endometrial carcinomas. Histological type, myometrial invasion, histological grade of tumor, and cervical involvement require additional surgery. The pathologist’s intraoperative diagnosis provides guidance in this process. The aim of this study is to assess the reliability of intraoperative frozen diagnosis in our laboratory during surgical operations for staging endometrial carcinoma. Materials and Methods: We screened all cases between January 2019 and April 2022, which we applied frozen sectioning with preliminary diagnosis of endometrial carcinoma and endometrial hyperplasia with atypia. Out of 212 cases, we focused on 151, whose frozen section reports were accessible. Histological type and grade, tumor diameter, myometrial invasion, cervical and adnexal involvement were evaluated retrospectively in frozen and paraffin sections. Tumor diameter was categorized as <2 cm and ≥2 cm, myometrial invasion was categorized as more superficial than 50% and deeper than 50%. Results: Compatibility of frozen sections with paraffin sections are found as 98.6% for histological type, 74.8% for histological grade, 82.8% for myometrial invasion, 90.7% for tumor diameter, 91.4% for cervical invasion, and 99.3% for ovarian metastasis. Conclusion: The results of intraoperative frozen diagnosis of endometrial cancers performed in our department are largely consistent with the results of paraffin diagnosis. This result is concordant with what has been shown in the literature. Intraoperative frozen procedure is necessary and reliable to avoid unnecessary lymphadenectomy in patients with high morbidity.

Özet

Amaç: Endometrial kanser gelişmiş ülkelerde jinekolojik maligniteler arasında ilk sıradadır. Bilateral salpingooferektomiyle birlikte total histerektomi; erken evre endometrial karsinomlarda standart tedavidir. Histolojik tip, myometrial invazyon, tümörün histolojik derecesi ve servikal tutulum ek cerrahi prosedürleri gerektirir. Patoloğun intraoperatif tanısı bu süreçte yol göstericidir. Bu çalışmanın amacı; laboratuvarımızda, endometrial karsinomun evreleme cerrahi prosedürü sırasında intraoperatif frozen tanının güvenilirliğini değerlendirmektir. Gereç ve Yöntem: Çalışmamızda 2019 ocak ayı ile 2022 nisan ayı arasında, endometrial karsinom ve atipili endometrial hiperplazi ön tanısı ile frozen çalışılan olguların hepsi taranmış olup; 212 olgudan, frozen raporlarına ulaşılabilen 151 olgu değerlendirilmeye alınmıştır. Histolojik tip ve derece, tümör çapı, myometrial invazyon, servikal ve adneksiyal tutulum; frozen ve parafin kesitlerinde retrospektif olarak değerlendirilmiştir. Tümör çapı <2 cm ve ≥2 cm olarak , myometrial invazyon ise %50’den yüzeyel ve %50’den derin olarak kategorize edilmiştir. Bulgular: Frozen kesitlerin parafin kesitlerle uyumluluğu; histolojik tip için %98.6, histolojik derece için %74.8, myometriyal invazyon için %82.8, tümör çapı için %90.7, servikal invazyon için %91.4 ve over metastazı için %99.3 olarak bulunmuştur. Sonuç: Bölümümüzde uygulanan endometrial kanserlerin intraoperatif frozen tanı sonuçları, parafin tanı sonuçları ile büyük oranda uyumludur. Bu durum şimdiye kadar ortaya konan ilgili literatür ile benzerlik göstermektedir. Sonuçta hastaların morbiditesi yüksek olan gereksiz lenfadenektomiye maruz kalmaması için intraoperatif frozen prosedürü gerekli ve güvenilir bir uygulamadır.
