To answer your question, yes, adjunctive chemotherapy is sometimes recommended for the type of cancer your dad is diagnosed with.
Adjunctive chemotherapy is used to kill cancer cells in addition to the radiation recommended. Although, as with any of the treatments for cancer, adding chemotherapy could also cause additional side effects associated with chemotherapy, such as fatique, loss of appetite, and decrease red and white blood counts.
Parotid gland cancer is a more rare cancer, with that in mind; you may want to ask the oncologist and radiation doctor about their experience with treating this type of cancer. You may also request that they share the clinical guideline they are following when treating your dad.
The National Cancer Institute web site provides excellent detailed information regarding standards of care/treatment for head and neck cancers. You can access this information by clicking on this link. http://www.cancer.gov/cancertopics/factsheet/sites-types/head-and-neck
I would also encourage you and your dad to seek a second opinion and or look for treatment that is provided by a team of specialists. Specifically for your dad, the following specialists would be recommended, oral surgeon or a throat surgeon, pathologist, medical oncologist, radiation oncologist, dentist, dietitian, social worker, and a nurse.
