Reduced Side Effects, Increased Potential for Cure in Some

Cancers of the head, neck and skull base are difficult to treat, depending upon the proximity of the tumor to the many essential organs in the region. By reducing radiation dose to these organs, proton therapy can decrease side effects, and/or allow higher doses of radiation to increase the chance of cure.

Current indications for proton therapy for head, neck and skull base tumors, and the benefits of proton treatment, include:

Oropharyngeal cancers (tonsil, base of tongue, soft palate, etc.)

  • Lowers the rates of feeding tube usage, as well as the burden of taste and appetite changes, as compared to IMRT [1]
  • Results in less weight loss, dry mouth and fatigue, and quicker return to work [2,3]

Paranasal Sinus cancers (maxillary sinus, nasal cavity, ethmoid sinus, etc.)

  • Lowers the risk of tumor recurrence as compared to treatment with conventional radiation [4]

Skull base tumors (chordomas, chondrosarcomas, etc.)

  • Allows for optimal dosage to increase the chance of cure [5]

Recurrent tumors

  • Allows for curative doses while sparing normal tissues that have previously been irradiated, with promising results [6]
