Endoscopic Ultrasound Plus Submucosal Injection for Early Esophageal Cancer

January 23, 2017 updated by: Jian-jun Li, Sun Yat-sen University

Efficacy Study of Endoscopic Ultrasound Combining With Submucosal Saline Injection for Pretreatment Staging of T1a and T1b in Patients With Early Esophageal Cancer

Preoperative accurately staging T1a or T1b in early esophageal cancer is vital for the choices of treatment. At present, the main diagnostic method for early esophageal cancer is endoscopic ultrasound (EUS). However, the accuracy of EUS alone is poor. Thus, it is necessary to improve endoscopic ultrasound examination methods. This project is concerning on the efficacy of EUS combining with submucosal injection of saline for staging T1a and T1b-esophageal cancer. Patients and methods: 80 cases of pathological confirmed early esophageal cancer were randomly divided into two groups: endoscopic ultrasonography group (EUS group) and EUS combining with submucosal injecting saline group (EUS+SIS group). All the cases will be performance by endoscopic or surgical resection; postoperative pathologic diagnosis will be obtained involving echo, depth, margin and other features. The EUS results of two groups of patients will be compared with pathologic results. From comparison, the efficacy and accuracy of EUS+SIS for staging T1a and T1b in esophageal cancer patients will be validated. Through this study, the investigators may develop a routine diagnostic and accurately staging method for early esophageal cancer patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Experimental: Submucosal injection combining with EUS
The enrolled patients will be accepted submucosal injection of saline,then ultrasonography will performed(EUS+SIS group).So,stages of EUS in these early esophageal cancer will be recorded and compared with the pathological stages afer endoscopic mucosal resection(EMR) or endoscopic submucosal dissection(ESD) or esophagectomy.
Device: submucosal injection needle ; EUS
The patients will accepted submucosal injection of 5ml saline followed by ordinary endosonography(EUS) before surgery or endoscopic dissection.
Other Names:
  • submucosal injection needle:Olympus,NM-20K-0423;
  • EUS:Olympus,UM2000
Placebo Comparator: ordinary endosonography(EUS)
The enrolled patients will accept ordinary ultrasonography .So,stages of EUS in these early esophageal cancer will be recorded and compared with the pathological stages afer endoscopic mucosal resection(EMR) , endoscopic submucosal dissection(ESD) or esophagectomy.
Device: ordinary endosonography(EUS)
