ABSTRACT
Introduction: Rectal cancer represents a health problem nowadays worldwide, for that reason an accurate clinical staging of the disease is fundamental to define the proper behavior to follow.Objective: To determine the efficacy of endoscopic ultrasound for staging rectal cancer.
Methods: A descriptive study was carried out, from January 2014 to March 2016 in Cuban National Center of Minimal Access Surgery in 33 patients (17 men and 16 women) who had undergone endoscopic ultrasound and who underwent surgery too. Their endoscopic ultrasound staging were compared with their anatomopathological reports of the surgical pieces obtained. Global concordance and diagnostic efficacy were calculated.
Results: The overall concordance for stage T was 57.6% and 87.9% for N. The diagnostic accuracy in the patients that received adjuvant treatment previously was lower than the group of patients that not received it. The diagnostic efficacy by substeps T resulted in respective values of sensitivity and specificity of 71.43% and 84.6% in T1; 76.9% and 70.0% in T2; and 42.8% and 96.2% in T3.
Conclusions: The overall concordance in T was lower than that reported in the literature consulted as well as the diagnostic efficacy of the technique, because 17 patients had previous adjuvant treatment. There were no significant results in the evaluation of stage N.
