Treatments for stage 0 esophageal cancer

The following are treatment options for stage 0 esophageal cancer. Your healthcare team will suggest treatments based on your needs and work with you to develop a treatment plan.

Endoscopic treatments

You may be offered an endoscopic treatment for stage 0 esophageal cancer.

Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) remove the inner layer, or mucosa, of the esophagus. You may be offered EMR or ESD to treat small, very early stage tumours that are only in the mucosa and have not grown deeper into the layers of the esophagus.

Radiofrequency ablation (RFA) uses a high-frequency electrical current to destroy cancer cells. You may be offered RFA as an alternative to surgery for stage 0 esophageal cancers, so that the esophagus doesn’t have to be removed. It is often used after EMR to make sure all the cancer cells have been removed from the area.

Photodynamic therapy (PDT) uses a photosensitizer drug to make cells sensitive to light. You may be offered PDT if you cannot have other endoscopic treatments. It may also be used to remove abnormal areas that are left behind after EMR.


You may be offered an esophagectomy for stage 0 esophageal cancer. This surgery removes all or part of the esophagus. Sometimes part of the stomach is removed as well.
