Eligibility
Inclusion criteria
Inclusion criteria: 1. Subject is 18-85 years of age, inclusive; 2. A lesion in the squamous esophagus that is visible with white light endoscopy and contains a type 0-IIa, 0-IIb and/or 0-IIc component; 3. After Lugol’s staining the lesion and surrounding USLs (i.e. the treatment area; TA) measures ≥2cm and ≤6cm and encompasses ≤2/3 of the circumference; 4. A histological diagnosis of HGIN or ESCCA in biopsies obtained anywhere from the TA; 5. No infiltration into the submucosa or beyond or metastatic disease on endoscopic ultrasound (EUS) and CT-scan of thorax and upper third of the abdomen; 6. Subject is eligible for treatment and follow-up endoscopy and biopsy as required by the protocol; 7. Written informed consent.
Exclusion criteria
Exclusion criteria: 1. Any type 0-I or 0-III lesion in the esophagus; 2. Any other neoplastic lesion in the squamous esophagus that is visible with white light endoscopy and can not be included in the TA to meet its maximum size requirements; 3. Any unstained lesion after Lugol’s staining elsewhere in the esophagus that can not be included in the TA to meet the its maximum size requirements and contains HGIN or ESCC upon biopsy; 4. Any N or M positive status; 5. Any prior endoscopic resection or endoscopic ablation therapy of the esophagus within a 3 cm range of the TA; 6. Any history of a non-squamous cell cancer of the esophagus, or any history of a squamous cell cancer of the esophagus (any stage) prior to 12 months before screening for this trial; 7. Any prior radiation therapy to the esophagus; 8. Any previous esophageal surgery, except fundoplication without complications (i.e. no slippage, dysphagia, etc).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The percentage of subjects with complete endoscopic removal of the qualifying lesion including pre-randomisation markers at the first ER section; 2. The percentage of subjects with no HGIN or ESCCA in biopsies obtained within 1-cm of the ER scar at 3 months follow-up. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The number of resections required for complete endoscopic removal of the qualifying lesion; 2. The time required for the initial ER, defined as the time between randomization (after placement of the electrocoagulation markers) and the end of endoscopy (after the complete endoscopic removal of the qualifying lesion (by ER and/or argon plasma coagulation), the treatment of any acute complications (e.g. bleeding), and removal of the ER specimens); 3. The percentage of subjects in whom argon plasma coagulation is required for complete endoscopic removal of the qualifying lesion; 4. The rate of complications, defined as being either “acute” (occurring immediately during the endoscopic procedure), “early” (occurring after the endoscopic procedure but within 48 hours) or “delayed” (occurring after 48 hours); 5. The percentage of subjects with HGIN or ESCCA diagnosed in biopsies/ER-specimens obtained outside the 1-cm margin of the ER scar at 3 months follow-up; 6. The maximum diameter, maximum thickness, and maximum thickness of the submucosal layer of the resection specimens obtained; 7. The costs of the endoscopic resection procedures (based on the time required for the procedure and the cost of disposables). | — |
