Trial Information

Phase IIB Study of Trimodality Management of Clinical T1bN0M0 Cancers of the Esophagus

The Study Treatment:

5-fluorouracil and docetaxel are designed to stop the growth of cancer cells, which may
cause the cells to die. Docetaxel may also damage blood vessels in tumor tissue.

The radiation therapy in this study will be either intensity modulated radiation therapy
(IMRT), which is a form of photon-based radiation therapy, or proton beam therapy (PBT).
This will be up to your doctor. Both IMRT and PBT are designed to give radiation to the
tumor area and limiting radiation exposure to nearby organs such as the lungs, heart, and
spinal cord.

The surgery in this study removes part of the esophagus and nearby lymph nodes. The type of
surgery will be the doctor's decision based on the location of the tumor in the esophagus.
It will either be laparoscopic surgery (a minimally invasive procedure through small holes
made in the abdomen) or open surgery (through the chest wall).

Study Treatment Administration:

If you are found to be eligible to take part in this study, you will receive radiation
therapy and chemotherapy on the following schedule for up to 5 1/2 weeks. If there are
holidays on the scheduled treatment days, the schedule may be slightly different and the
study staff will discuss this with you.

- Radiation therapy will be given Monday through Friday. This will take about 30
minutes, including about 10-15 minutes for the radiation treatment.

- 5-fluorouracil will be given by vein, continuously for about 96 hours a week (Monday
through Friday).

- Docetaxel will be given by vein over about 1 hour, 1 time a week (on Mondays).

5-fluorouracil will be given using a portable pump about the size of a personal CD
player. You will need to carry this portable pump with you for about 96 hours each
week.

Docetaxel will be given through a central venous catheter. A central venous catheter is a
sterile flexible tube that will be placed into a large vein while you are under local
anesthesia. Your doctor will explain this procedure to you in more detail, and you will be
required to sign a separate consent form for this procedure. The catheter will be removed
at the end of Week 5.

Before every dose of docetaxel, you will receive dexamethasone to lower the risk of side
effects. Dexamethasone will be given by vein over a few seconds.

Your doctor will let you know if and when you are eligible to have surgery. In this study,
the surgery must be performed within 8-10 weeks after you finish chemotherapy and radiation
therapy. You will be asked to sign a separate consent form that describes the surgery and
anesthesia (numbing medicine) and their risks in more detail. The screening tests that will
help your doctor decide if you are eligible to have surgery include the scans and endoscopy
described below (4-6 weeks after radiation and chemotherapy).

You will no longer be able to receive radiation and chemotherapy if the disease gets worse
or intolerable side effects occur. You will not be able to have surgery if the doctor
decides surgery is not in your best interest (for example, if the disease or your general
health gets worse).

Study Visits:

During Study Therapy Blood (about 3 tablespoons) will be drawn for routine tests during Week
3 of radiation and chemotherapy.

Follow-Up:

At 4-6 weeks after your last dose of radiation and chemotherapy, the following tests and
procedures will be performed:

- You will have a CT scan of the chest and a whole-body PET/CT scan to check the status
of the disease.

- You may have an endoscopy of your esophagus with 1 or more biopsies of the tumor to
check the status of the disease. The number of biopsies you have will be the doctor's
decision at the time of the procedure, based on the status and location of the disease.

- Blood (about 3 tablespoons) will be drawn for routine tests.

- You will fill out 3 quality-of-life questionnaires. This should take about 10-15
minutes.

About 4 weeks after surgery, you will fill out 3 quality-of-life questionnaires. You will
then fill out 2 quality-of-life questionnaires at 6 of your routine follow-up visits after
surgery.

Every 3-6 months in the first 3 years after your last dose of radiation and chemotherapy,
then every 6 months in the next 2 years, and every year after that from then on, the
following tests and procedures will be performed:

- You will have a CT scan of the chest or a whole-body PET/CT scan to check the status of
the disease.

- You will have an endoscopy of your esophagus to check the status of the disease during
every follow-up visit in Year 1. After that, you will have an endoscopy of your
esophagus at follow-up visits anytime the doctor decides it is needed. You will have 1
or more tumor biopsies at these follow-up visits if the doctor decides they are needed,
based on the status and location of the disease. This will be decided at the time of
the endoscopy.

Biomarker Testing:

If leftover tumor tissue is available from before you joined the study, the leftover tissue
will be used for genetic biomarker testing. If you do not have leftover tumor tissue
available from before you joined the study, leftover tissue from study procedures will be
used for genetic biomarker testing.

This is an investigational study. Docetaxel and 5-fluorouracil are FDA approved and
commercially available to treat esophageal cancer. However, it is investigational to give
these drugs to patients with early-stage esophageal cancer.

It is investigational to give the combination of chemotherapy, radiation therapy, and
surgery to patients with early-stage esophageal cancer.

Up to 30 patients will take part in this study. All will be enrolled at MD Anderson.
