Treatment
1. Surgery: surgery is the first choice for digestive tract cancer, it is not very much possible to resect the large squamous cell carcinoma. A pre-operational radiotherapy can be considered, and a surgery can only be performed after the tumor is reduced.
2. Radiotherapy: combined radiotherapy and surgery can increase the resection rate and improve the survival rate, so it is more appropriate to do the operation after 3-4 weeks.
3. Chemotherapy: the combination of chemotherapy and surgery.
