What are the advantages of radiotherapy for esophageal cancer? Esophageal cancer is a common malignant tumor, radiotherapy is an important means to treat esophageal cancer, especially for the symptoms of advanced esophageal cancer metastasis, in order to relieve and treat esophageal cancer, what are the advantages of radiotherapy for esophageal cancer? Radiotherapy is one of the important means of comprehensive treatment for esophageal cancer. Radiotherapy before and after surgery or chemotherapy can shrink tumor, eliminate local residual lesions, eliminate local metastatic lesions and apply to patients who cannot be operated, which can improve the cure rate and reduce recurrence and metastasis. 1.Shrink tumor It is difficult to treat or resect more advanced esophageal cancer surgically, but after preoperative radiotherapy, most patients’ tumor shrinks, which increases the surgical resection rate and improves the postoperative survival rate; generally, it does not increase the difficulty of surgery and does not increase surgical complications such as anastomotic leakage. 2.Elimination of local residual lesions Postoperative radiotherapy for palliative resection of esophageal cancer not only eliminates residual lesions, but also improves local control rate and patient survival rate. 3.For patients who cannot be operated High-grade esophageal cancer, which is difficult and risky to be operated, can also be treated well with radical radiotherapy; some other patients with esophageal cancer cannot be operated due to poor physical condition or complications can also be considered for radical radiotherapy. 4.elimination of local metastatic lesions For those esophageal cancer patients with advanced stage, there are often symptoms such as bone pain or superior vena cava compression and cancerous bleeding caused by cancer metastasis, radiotherapy can often alleviate the symptoms well and achieve the purpose of prolonging life.
