2. Surgically resectable clinical stage T1N1-3 or T2-3N0-3 and no clinical evidence of metastatic spread are eligible (M0).
3. Maximum length (based on best information available, with EGD preferred) and width of the tumor as seen on CT not exceeding 8 cm and 5 cm respectively.
4. ECOG performance status ≤ 2
5. Patient able to begin radiation treatment within 30 calendar days of signing the informed consent form.
6. Age ≥ 18 and ≤ 80.
7. Adequate hematological, renal, hepatic and pulmonary function as defined by:

1. Hemoglobin > 100 g/L
2. Platelet count > 100x109/L
3. Absolute neutrophil count > 1.5x109/L
4. Total bilirubin ≤ 1.5x the upper limit of institutional normal
5. Creatinine ≤ 120 µmol/L
6. FEV1 ≥ 1.5 L
8. Patients capable of childbearing are using adequate contraception.
9. Written and informed consent of patient.

Exclusion Criteria:

1. Past or current history of malignancy other than entry diagnosis except for non-melanomatous skin cancer, or curatively treated carcinoma in situ of the cervix or a cured malignancy more than 5 years prior to enrollment
