You are being asked to take part in this study because you have cancer of the oropharynx (tonsillar pillar, tonsillar fossa, soft palate, and/or base of the tongue) and you are going to have proton beam radiotherapy (radiation treatment).
The purpose of this study is to collect information from the questionnaire and medical records to see what effects proton beam radiation has cancer and collect and analyze morbidity outcomes: incidence of xerostomia (dry mouth) and tumor control.
Protons may offer a unique advantage. It may be possible to design treatments where surrounding or non-tumor-overlapping tissues could be spared.
Primary Outcome Measures:
- Collect and analyze morbidity outcomes: incidence of xerostomia [ Time Frame: Every 4 months until final analysis ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- Collect and analyze tumor control outcomes. [ Time Frame: When each patient has been followed for a minimum of 12 months and then again after 24 months. ] [ Designated as safety issue: No ]

If you take part in this study, you will be asked eight questions about dry mouth symptoms that you may have. Answering these questions will take less than 10 minutes. You will have the standard treatment for your type of cancer, which has been determined by your cancer doctor.
Patients are stratified:
- Stage I (T1N0)- RT alone
- Stage II (T2N0) - RT alone
- Favorable Stage III (T1N1/T2N1)and selected IV (T1-T2 early N2b)with two or less LN and 2 or less cm diameter LN - RT alone
- Unfavorable Stage III (T3N0) and selected IV (any T, N2c/N3) - RT + chemo
Treatment:
Photon/Proton radiation per standard of care
Chemo if indicated: CDDP 30 mg/m2 q week or CDDP 100 mg/m2 q 3 weeks at the discretion of medical oncologist
