Brief Summary

Esophageal cancer is a deadly disease that is becoming increasingly common in the United States. Barrett's esophagus (BE) is a pre-cancerous state that can develop into esophageal cancer, but is highly treatable. Progression of BE to esophageal cancer is still common due to missed diagnosis of Barrett's esophagus recurrence following treatment. Wide-Area Trans-Epithelial Sampling (WATS-3D) is a new technology that uses brush sampling to examine larger areas of the esophagus as compared to conventional biopsies. Preliminary studies show improved detection of cancerous changes in Barrett's esophagus surveillance. The investigators hope to see if the addition of WATS-3D increases the rate of detection of recurrent BE following treatment, which is of the utmost importance since it would allow for earlier re-treatment of disease and ultimately allow for prevention of progression to esophageal cancer.

Conditions

Barrett Esophagus; Esophageal Cancer

Outcome Measures

Primary Outcomes (1)

• To assess the additive diagnostic yield as assessed by proportion of patients with recurrence be use of WATS-3D

  To assess the additive diagnostic yield of WATS-3D sampling beyond that of standard biopsies for detection of IM or dysplasia (recurrence) in patients who have undergone EET for BE-related neoplasia. The rates of recurrence as determined by the proportion of patients (percentage) deemed to have recurrence of BE on tissue sampling will be compared between samples obtained by WATS-3D vs forceps biopsies.

  2 years

Secondary Outcomes (2)

• To assess if there is a difference in diagnostic yield of WATS-3D based on CE-IM definition between one and two or more endoscopies

  3 years

• To assess if the order by which tissue is sampled affects the diagnostic yield of WATS-3D by comparing the proportion of patients with recurrence between groups.

  3 years

Study Arms (2)

Post-EET Surveillance Group: WATS-3D samples followed by Forceps biopsies

ACTIVE COMPARATOR

Sampling will occur with WATS-3D followed by forceps biopsies. For each patient, resection samples will be identified by the endoscopy method used to locate the sample as either HD-WLE/NBI or WATS-3D. For each method of detection, the highest grade of histology for each patient will be assigned based on the identified samples. Dysplasia detected on random biopsies will be attributed HD-WLE/NBI given it is part of the standard of care.

Device: WATS-3D tissue sampling prior to forceps biopsies

Post-EET Surveillance Group: Forceps biopsies followed by WATS-3D samples

Interventions

WATS-3D tissue sampling prior to forceps biopsies DEVICE

WATS-3D is a brush-based tissue sampling technique. Abrasive brush sampling of large areas of the esophagus pick up cells to obtain trans-epithelial specimens. This technique samples much larger tissue areas than standard forceps biopsies. Analysis is then done by proprietary neural-network based computer scanning and molecular diagnostics to identify abnormal cells.

Post-EET Surveillance Group: WATS-3D samples followed by Forceps biopsies

WATS-3D tissue sampling following forceps biopsies DEVICE

WATS-3D is a brush-based tissue sampling technique. Abrasive brush sampling of large areas of the esophagus pick up cells to obtain trans-epithelial specimens. This technique samples much larger tissue areas than standard forceps biopsies. Analysis is then done by proprietary neural-network based computer scanning and molecular diagnostics to identify abnormal cells. This will be done after forceps biopsies in this arm.
