Trial Information

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

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

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.
