[|AI|]  Hi, Thanks for writing in. A stage 4 adenocarcinoma of parotid gland responds to treatment with radiation and chemotherapy as given to you. The size looks a little larger and there are lymph nodes. As surgical treatment was not possible, you have been given the appropriate recommended radiation and chemotherapy. It will help to know how much tumor volume reduction has occurred and if it has been significant then survival rate will be high. From present data collected on salivary gland cancer stage 4 under treatment the survival rates have been put at 39% at five years. The 5-year survival rate refers to the percentage of patients who live at least 5 years after their cancer is diagnosed. Of course, many people live much longer than 5 years (and many are cured). To get 5-year survival rates, doctors have to look at people who were treated at least 5 years ago. Improvements in treatment since then may result in a better outlook for people now being diagnosed with salivary gland cancer.
