The radiotherapy department of Yancheng Second People’s Hospital, Bo Huiming: If you must do surgery, you can do preoperative radiotherapy to separate the adhesions with the aorta (surgery 3 weeks to 4 weeks after 30-40 Gy of rapid radiotherapy), so that the safety of surgery will be greatly improved, or you can do preoperative induction chemotherapy, but this may delay the surgery, because you have to do one or two cycles before surgery. In fact, you can choose to do combined radiotherapy and chemotherapy, even radiation therapy alone can achieve more satisfactory results. Of course, if the tumor has invaded the aorta, the risk of hemorrhage caused by radiotherapy is not higher than that of surgery, because of the diversification of treatment methods, it is not necessary to do surgery. Remember that radiation therapy as a radical treatment measure can also stand alone, (control of toxic reactions) combined with chemotherapy will make the treatment more effective. If the symptoms of obstruction are severe and it is expected that the patient will not be able to eat in a short period of time, you can first place an esophageal stent and then perform radiotherapy.
