Abstract

Introduction: The exact extent of rectal cancer and regional lymph node involvement are essential for providing the optimal treatment. Aim: The aim of the authors was to evaluate the diagnostic accuracy of endoscopic ultrasonography in routine clinical staging of rectal cancer. Method: Outcomes of endoscopic ultrasonography performed between 2006 and 2012 for rectal cancer staging were retrospectively analyzed. The correlation between the endoscopic and pathological stages was evaluated. Results: In patients without neoadjuvant chemotherapy the sensitivity (75% and 73%) and specificity (74% and 80%) of endoscopic ultrasonography for differentiating T1 and T2 stages (respectively) were high, however, it was significantly decreased in differentiation of T3 stage (58%). A weak association was found in different N stages (45-62%). The diagnostic accuracy of endoscopic ultrasound was reduced significantly after the oncological treatment due to the overevaluation (27%) of the findings. After a relatively short learning curve (30 examinations) high correlation was detected between pT and uT stages. Conclusions: Endoscopic ultrasonography provides great help in staging early rectal cancers. Due to the lower sensitivity in patients receiving neoadjuvant therapy, it is not a useful tool after down-staging.
