Purpose.
This retrospective study examined the usefulness of barium esophagography, focusing on the luminal stenosis, in the response evaluation of neoadjuvant chemoradiotherapy (NACRT) in patients with esophageal cancer.
Materials and Methods.
Thirty-four patients with primary advanced esophageal cancer (≥T2) who were treated with NACRT before surgical resection were analyzed.
All patients underwent barium esophagography before and after NACRT.
The tumor length, volume, and percent esophageal stenosis (PES) before and after NACRT were measured.
These values and their changes were compared between histopathologic responders (n=22) and nonresponders (n=12).
Results.
Posttreatment tumor length and PES in responders (4.5 cm ± 1.1 and 33.0% ± 18.5) were significantly smaller than those in nonresponders (5.8 cm ± 1.9 and 48.0% ± 12.9) (P=0.018).
Regarding posttherapeutic changes, the decrease in PES in responders (31.5% ± 13.9) was significantly greater than that in nonresponders (14.4% ± 10.7) (P<0.001).
The best decrease in PES cutoff with which to differentiate between responders and nonresponders was 18.8%, which yielded a sensitivity of 91% and a specificity of 75%.
Conclusions.
Decrease in PES is a good parameter to differentiate responders from nonresponders for NACRT.
Barium esophagography is useful in response evaluation to NACRT in patients with locally advanced esophageal cancer.
