A Phase III Study of En Bloc Versus Non-En Bloc Esophagectomy in Esophageal Cancer

August 10, 2012 updated by: Paul C. Lee, Weill Medical College of Cornell University

A Phase III Study of En Bloc Versus Non-En Bloc Esophagectomy in Patients With Locally Advanced Esophageal Cancer

The purpose of this study is to test 2 different methods of surgery to remove cancer in the esophagus. This research is being done to see whether removing more tissue and lymph nodes surrounding the tumor in the esophagus (known as transthoracic en bloc esophagectomy) offers better control of the cancer than removing less tissue and lymph nodes (known as non-en bloc esophagectomy).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of this study is to determine the 5-year disease-free survival, overall survival, and time to progression comparing (Arm A) transthoracic en bloc esophagectomy and (Arm B) transhiatal or transthoracic non-en bloc esophagectomy. Randomization to the two surgical arms will take place after the patient has given written informed consent and eligibility has been established. Patients will be informed of their randomized arm prior to the day of surgery. Preoperative chemotherapy may be administered at the discretion of the treating physician. Adjuvant chemotherapy and/or radiotherapy will be prescribed at the discretion of the treating physician. All patients will be followed for recurrence and survival for 5 years.

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 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients with cT2-T3/N0-N1-M1a-M1b(lymph node metastasis only) esophageal squamous cell and adenocarcinoma who have potentially resectable disease.
  • Karnofsky performance status greater than or equal to 80%.
  • Pulmonary and cardiac function must be acceptable for surgery according to institutional standards.
  • Acceptable hepatic, renal and bone marrow function.
  • Age 18 or older.
  • Patients may receive preoperative chemotherapy and/or radiation therapy as part of their clinical care.

Exclusion Criteria:

  • Patients with clearly unresectable or metastatic esophageal cancer or clinical stage I esophageal cancer.
  • Significant psychiatric illness that would interfere with patient compliance.
  • Patients with any other serious underlying medical condition that would impair the ability of the patient to receive or comply with protocol treatment.
  • Patients with a significant history of unstable cardiovascular disease (e.g., inadequately controlled hypertension, or angina; myocardial infarction within the previous 6 months; ventricular cardiac arrhythmias requiring medication; congestive heart failure that in the opinion of the treating physician should preclude the patient from protocol treatment.
  • Uncontrolled diabetes mellitus or uncontrolled infection, including HIV or interstitial pneumonia or interstitial fibrosis.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: A
En bloc esophagectomy is performed through a transthoracic approach by removing the tumor-bearing esophagus, the pericardium anteriorly, both pleural surfaces laterally, as well as the thoracic duct and all other lymphoareolar tissue wedged posteriorly between the esophagus and the spine, and en-bloc resection of all nodal groups in the middle and lower mediastinum as well as the upper abdomen.
Procedure: Esophagectomy
Comparison of en-bloc vs. non-en bloc esophagectomy
Active Comparator: B
Transhiatal esophagectomy is performed through an abdominal incision and a neck incision. The stomach is mobilized, and the left gastric vessels are transected at its origin. Celiac lymph nodes are dissected, and the intrathoracic esophagus is dissected bluntly through the hiatus and through the neck. The cervical esophagus is divided at the level of the neck. After the esophagogastrectomy is performed, a gastric tube is created. An esophagogastrostomy is then performed in the neck. If a transthoracic approach is used, dissection will be as described for the transhiatal approach.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Disease free survival defined as the time from surgical resection to the time of recurrent disease, death from esophageal cancer, or death from any cause.
Time Frame: CT scans will be performed every 6 months for 5 years.
CT scans will be performed every 6 months for 5 years.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
To determine 5-year overall and disease-specific survival in arm A and arm B
Time Frame: CT scans every 6 months for 5 years
CT scans every 6 months for 5 years
