Abstract
INTRODUCTION
Rectal ultrasonography is a basic method for staging rectal cancer. Tissue changes after neoadjuvant treatment alter the accuracy of the method.
AIM
The aim of the authors was to assess the accuracy of rectal ultrasonography after preoperative chemo-radiotherapy compared to the initial staging accuracy.
METHOD
Rectal ultrasounds performed between 2006 and 2014 were assessed retrospectively. Ultrasonographic and pathological T and N stages were compared both in case of initial staging (control group) and re-staging.
RESULTS
T staging was accurate in 70% in the control group and in 61% in re-staging. Rate of overstaging was 31% after neoadjuvant treatment. None of the ypT0 cases were identified. N staging accuracy was 64% in the control group and 61% in re-staging.
CONCLUSIONS
Neoadjuvant treatment impairs the accuracy of rectal ultrasound. The role of re-staging with rectal ultrasonography is debatable in the assessment of the efficacy of oncological treatment and surgical planning. Orv. Hetil., 2016, 157(30), 1193-1197.
