Validation of the Japanese Esophageal Society classification for prediction of invasion depth of superficial squamous cell carcinoma in a Western populatio
- Conditions
- All patients with a suspicious or known (pre)malignant esophageal squamous cell lesion
Recruitment & Eligibility
- Status
- Recruiting
- Sex
- Not specified
- Target Recruitment
- 94
In order to be eligible to participate in this study, a subject must meet all of the following criteria:
- Western patients with a suspicious or known (pre)malignant esophageal squamous cell lesion
- Photos and videos available using WLE, magnification endoscopy, NBI, and (when available) lugol’s iodine staining.
A potential subject who meets any of the following criteria will be excluded from any analysis with regard to the prediction of invasion depth:
- No data on histological invasion depth available.
- Patients who underwent esophagectomy with neoadjuvant (chemo)radiation therapy.

- Primary Outcome Measures
Name Time Method The overall accuracy of the JES-classification for predicting the invasion depth of ESCC
- Secondary Outcome Measures
Name Time Method -Presence and size of avascular areas in the esophageal squamous cell lesions.<br>-Paris-classification of the esophageal squamous cell lesions. <br>-Presence of intervascular background coloration.<br>-Positive/negative pink color sign with Lugol’s iodine staining. <br>-The predicted invasion depth of the esophageal squamous cell lesions considering the above mentioned parameters.<br>-Inter- and intraobserver agreement between Western expert endoscopists and non-expert endoscopists, and Japanese endoscopists.
