•1\) Disease criteria: Subject’s esophageal cancer must meet all of the following:
•a) Confirmation: Histologically or cytologically confirmed squamous cell carcinoma or adenocarcinoma of the esophagus or gastroesophageal junction. Biopsy or cytology of the primary tumor or of involved regional lymph nodes is acceptable.
•b) Stage: Tumors must be TNM stage T2\-T3, N any, M0 (no evidence of disseminated cancer except regional nodes such as supraclavicular and celiac) as determined by endoscopic ultrasound.
•c) Disease extent: Disease must be limited to the esophagus or the gastroesophageal junction, including:
•i)Tumor does not extend more than 2 cm into the stomach
•ii)Tumor does not extend into proximal one\-third of the esophagus (Note: Bronchoscopy is required if tumor is \<26 cm from the incisors or at or above the carina)
•iii)No tracheal\-esophageal fistulas present
•iv) No apparent direct invasion by the tumor into the mucosa of the trachea or major bronchus as determined by bronchoscopy or other method.
•v) No vascular invasion or involvement by the tumor
•d) No evidence of metastatic disease: disease must be localized to the esophagus, including

•\- History of anaphylaxis to planned CT contrast agent; subjects with history of minor, mild allergic reactions (eg, hives, rash, pruritis) to planned CT contrast agent may be premedicated with prednisone or other medications per institutional standard of care
•\- Prior esophageal stent insertion, laser or photodynamic therapy
•\- Prior chest RT or major esophageal surgery
•\- Any prior receipt of cytotoxic chemotherapeutic agents
•\- Prior receipt of other cancer treatments (ie, Chelation therapy), vaccines or biological response modifiers/growth factors (ie, GM\-CSF, IL\-2\) within the past 4 weeks.
•Note: hormonal therapies (eg, tamoxifen, anastrozole) and topical agents (eg, 5\-FU, imiquimod) will be allowed; no washout period will be required for these agents.
•\- Prior malignancy unless disease free for \=3 years
•Note: basal cell/squamous carcinoma of the skin, in situ cervical or breast carcinoma, or superficial transitional cell bladder carcinoma will be allowed
•\- Significant currently active systemic diseases including uncontrolled diabetes, severe heart disease (New York Heart Association Class III or IV, see Section 13\.4\), uncontrolled hypertension, myocardial infarction within 3 months, severe bronchial obstruction, uncontrolled seizure disorder, or peripheral neuropathy greater than CTCAE grade 1
