Patient: In 1997, my mother was only 45 years old suffered from esophageal cancer, to the Shanghai Cancer Hospital to see the doctor said that my mother this is the early and mid-stage for the recovery should not be a problem, must be my mother is still young, we are full of hope to go to my mother’s treatment of choice of laser radiotherapy I just don’t understand my mother’s radiotherapy after half a year after the death of my mother, let us feel really very painful, why 3.5 cm of esophageal cancer said it is not terminal how to send my mother’s life, and is metastatic cancer cells. Esophageal cancer said it is not yet advanced how to send my mom’s life, and is the cancer cells metastasis. Bo Huiming, Department of Radiotherapy, Yancheng Second People’s Hospital: The therapeutic effect of esophageal cancer doesn’t depend on the size of the primary tumor, but (we) pay more attention to the depth of penetration of the tumor, the way of growth, and more importantly, the type of its pathology: if it is poorly differentiated or is a small-cell type, it will be easy to have distant metastasis, which usually means the failure of the treatment, and the description of the whole process of the treatment isn’t very precise. There is no way to tell where the problem lies, but most tumor failures are mainly recurrence and distant metastasis, as you said, it should be metastasis. Of course, it is also possible that infection, radioactive pneumonia, or perforation, etc. may be formed as a result of uncontrolled complications of treatment. Generally the natural survival of esophageal cancer (without treatment) is at least so long, so it may be that the condition has changed or the description is not accurate.
