PERİTONEAL KARSİNOMATOZİS HASTALARININ PREOPERATİF EVRELENDİRİLMESİNDE BİLGİSAYARLI TOMOGRAFİNİN ETKİNLİĞİ

Giriş: Peritoneal karsinomatozis (PK) hastalarında sitoredüktif cerrah için optimal hasta seçimi ve cerrahinin planlanması açısından preoperative evreleme çok önemlidir. Bu çalışmanın amacı preoperatif BT ile intraoperatif bulguları karşılaştırmak ve iki radyolog arasındaki korelasyonu ve uyumu araştırmaktır. Gereç ve Yöntem: İki radyolog 48 PK hastasının preoperatif BT incelemelerini çift kör olarak değerlendirdi. Evreleme için lezyon boyutu ve dağılımının değerlendirildiği Sugarbaker’ın tanımladığı Peritoneal Kanser İndeksi (PKİ) kullanıldı. İntraoperatif bulgular altın standart kabul edildi. Sonuçlar Wilcoxon işaretli sıralar testi, Spearman korelasyon testi, Kendall’ın tau-b testi ve Cohen’in kappa testi kullanılarak değerlendirildi. Bulgular: Ortalama toplam PKİ değeri intraoperatif 12.73 (±6.92), 1. radyolog için 11.08 (±6.34) ve 2. radyolog için 10.56 (±6.49) olarak bulundu. Her iki radyoloğun hesapladığı preoperatif PKİ değerleri ile intraoperatif PKİ değerleri arasında istatistiksel anlamlı fark saptandı (her iki radyolog için p=0.002). Her iki radyoloğun hesapladığı PKİ değerleri arasında istatistiksel anlamlı fark saptanmadı (p=0.123). Her iki radyoloğun hesapladığı PKİ değerleri ile intraoperatif skorlar arasında yüksek korelasyon saptandı (1. radyolog için rs=0.860, p

EVALUATION OF PREOPERATIVE COMPUTED TOMOGRAPHY IN STAGING PERITONEAL CARCINOMATOSIS PATIENTS

Introduction: We aimed to investigate the accuracy of computed tomography (CT) and evaluate the interobserver correlation and agreement between two radiologists in preoperative staging of peritoneal carcinomatosis (PC) patients. Material and Method: Two blinded radiologists retrospectively evaluated preoperative CT scans of 48 patients with PC. According to the Sugarbaker classification, the peritoneal cancer index (PCI) was scored based on lesion size and distribution. Intraoperative findings were regarded as the gold standard. The results were analyzed by the Wilcoxon signed-rank, Spearman’s correlation, Kendall’s tau-b, and Cohen’s kappa tests. Results: The mean PCI score was 12.73 (±6.92) for surgery, 11.08 (±6.34) for Radiologist 1, and 10.56 (±6.49) for Radiologist 2. A comparison of total PCI scores showed a significant difference between surgical PCI scores and preoperative CT PCI scores (for both radiologists p=0.002). There was no significant difference between the two radiologists’ total scores (p=0.123) with a very strong correlation (rs=0.921, p
