Beskrivelse
Inclusion Criteria:
- Subject is 18-80 years of age, inclusive
Subject meets at least one of the following inclusion criteria:
- Within the last 3 months, subject demonstrated a new diagnosis or a reconfirmed diagnosis of squamous MGIN and/or HGIN of the esophagus, or...
- within the last 3 months, subject demonstrated a new diagnosis of a flat-type (type 0-IIb) SCCA (G1/G2 only)
- On endoscopic examination, subject has at least one USL that measures at least 3 cm in at least one dimension and has MGIN or worse (MGIN+) on biopsy
- The maximum allowable linear length of "USL-bearing esophagus" is 12 cm
- Baseline EUS (all patients) shows no exclusionary findings for the trial
- CT scan of chest and upper third of the abdomen (all HGIN and SCCA patients) shows no exclusionary findings for the trial
- Subject is not pregnant nor has plans to become pregnant in the ensuing 12 months (confirmation of non-pregnant status in women of child-bearing age and ability required with urine or blood test)
- Subject is eligible for treatment and follow-up endoscopy and biopsy as required by the protocol
- The subject is willing to provide written, informed consent to participate in this clinical study and understands the responsibilities of trial participation
Exclusion Criteria:
the Eligibility CRF.
- Esophageal stricture preventing passage of a therapeutic endoscope
- Any prior endoscopic resection
- Any esophageal dilation in the past 12 months
- 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 3 months before screening for this trial
- Any N or M positive status, if patient has a present diagnosis of esophageal SCCA
- Any previous ablative therapy within the esophagus (photodynamic therapy, multipolar electrical coagulation, argon plasma coagulation, laser treatment, or other) or any radiation therapy to the esophagus.
- Any previous esophageal surgery, except fundoplication without complications (i.e. no slippage, dysphagia, etc)
- Evidence of esophageal varices detected within last 6 months or at initial RFA procedure
- Evidence of eosinophilic esophagitis on endoscopy and/or histology
- Report of uncontrolled coagulopathy with international normalized ratio (INR) > 2 or platelet count <75,000 platelets per µL (note: a complete blood count is not required for all subjects in this study)
- Subject is using aspirin, clopidogrel, or non-steroidal anti-inflammatory drugs that can not be discontinued 7 days before and after therapeutic sessions
- Subject has a known history of unresolved drug or alcohol dependency that would limit ability to comprehend or follow instructions related to informed consent, post-treatment instructions, or follow-up guidelines
- Subject has an implantable pacing device (examples; AICD, neurostimulator, cardiac pacemaker) and has not received clearance for enrollment in this study by specialist responsible for the pacing device
- Subject suffers from psychiatric or other illness deemed by the investigator as an inability to comply with protocol
- Subject has life expectancy less than 2 years

Eksperimentel: Radiofrequency ablation
To study the safety and effectiveness of radiofrequency ablation (RFA) using the HALO ablation system in completely eradicating the diseased epithelium in patients with ESCN
|
Patients with a histopathological diagnosis of moderate-grade intra-epithelial neoplasia (MGIN), high-grade intra-epithelial neoplasia (HGIN) and/or early flat-type SCCA of the esophagus, are treated with radiofrequency ablation, with repeat endoscopy and follow-up treatment at 3 month intervals.
