An Analysis of Thyroid Fine Needle Aspiration Biopsy Results According to the Bethesda System for Reporting Thyroid Cytopathology: A Cross-Sectional Retrospective Study

Öz

Background/Aims: Thyroid fine needle aspiration biopsy (TFNAB) is an effective and convenient evaluation method. It is the gold standard in preoperative evaluation. The Bethesda System for Reporting Thyroid Cytopathology is a standardized evaluation system that has been widely used all over the world. In this study, we aimed to investigate the compatibility of the TFNAB results, which we evaluated according to the Bethesda System for Reporting Thyroid Cytopathology. Methods: The data of 333(236 female, 97 male) patients, who underwent TFNAB between January 2020 and January 2022, were collected retrospectively. Their Bethesda categories, ages, and gender characteristics were recorded. Results: The mean age for the 333 patients included in the study was 46.46 ± 14.53 for the female patients and 50.19 ± 10.06 for the male patients. When all patients were examined, Nondiagnostic (B1), Benign (B2)were the most common cytologies. While benign cytology was observed at an earlier age, the suspicion of malignancy or the incidence of malignant cytology increased as the mean age of the patients increased. Conclusion: The Bethesda System for Reporting Thyroid Cytopathology is a widely accepted and reliable benchmark around the world in the evaluation phase of the cytopathological examination. In this study, we examined the cytopathological evaluation results of the patients who underwent thyroid FNAB at our center according to the Bethesda System for Reporting Thyroid Cytopathology. In terms of diagnostic cytology, we recommend aultrasonography-guided biopsy performed by an experienced clinician.

Tiroid İnce İğne Aspirasyon Biyopsi Sonuçlarının Tiroid Sitopatolojisini Raporlamak İçin Bethesda Sistemine Göre Analizi: Kesitsel Retrospektif Bir Çalışma

Öz

Amaç: Tiroidin ince iğne aspirasyon biyopsisi etklili ve kullanışıl bir değerlendirme yöntemidir. Preoperatif değerlendirmede altın standarttır. Tiroid sitopatolojisini raporlamak için Bethesda Sistemi, tüm dünyada yaygın olarak kullanılan standartlaştırılmış bir değerlendirme sistemidir. Bu çalışmada Bethesda Sistemi’ ne göre değerlendirdiğimiz ince iğne aspirasyon biyopsisi sonuçlarının uyumluluğunu araştırmayı amaçladık. Gereç ve Yöntemler: Ocak 2020-Ocak 2022 tarihleri arasında ince iğne aspirasyon biyopsisi uygulanan 333 (236 kadın, 97 erkek) hastanın verileri geriye dönük olarak toplandı. Bethesda kategorileri, yaşları ve cinsiyet özellikleri kaydedildi. Bulgular: Çalışmaya alınan 333 hastanın yaş ortalaması kadın hastalarda 46,46±14,53, erkekhastalarda 50,19±10,06 idi. Tüm hastalar incelendiğinde Non diagnostic (B1), Benign (B2) en sık görülen sitolojilerdi. Benign sitoloji daha erken yaşlarda görülürken hastaların yaş ortalaması arttıkça malignite şüphesi veya malign sitoloji görülme sıklığı artmaktaydı. SonuçTiroid sitolojisini raporlamak için Bethesda Sistemi sitopatolojik incelemenin değerlendirme aşamasında dünya çapında yaygın olarak kabul gören güvenilir bir kriterdir. Bu çalışmada merkezimizde ince iğne aspirasyon biyopsisi uygulanan hastaların sitopatolojik değerlendirme sonuçlarını Bethesda Sistemi’göre inceledik. Tanısal sitoloji açısından deneyimli bir klinisyen tarafından alınan ultrasonografi eşliğinde biyopsi yapılmasını öneriyoruz.
