Fractionated proton stereotactic radiotherapy (PSRT) is used to treat both adult and pediatric patients with a variety of diagnoses.

Fractionated proton stereotactic radiotherapy (PSRT) is used to treat both adult and pediatric patients with a variety of diagnoses. A multi-disciplinary approach may involve combining PSRT with surgery, chemotherapy as well as conventional x-ray therapy. The need for combined-modality treatments depends on the specific disease being treated as well as patient’s medical history. Pediatric and adult patients benefit from proton stereotactic radiotherapy by sparing normal tissue, which would otherwise be compromised using conventional x-ray therapy alone.

In pediatric patients, PSRT is used to treat tumors such as:

  • Astrocytoma
  • Craniopharyngioma
  • Ependymoma
  • Ewing sarcoma
  • Rhabdomyosarcoma
  • Tumors of the central nervous system (CNS) such as Medulloblastoma
  • Tumors of the eye such as Retinoblastoma

Special care is provided for young children, as they often require administration of general anesthesia for each PSRT treatment session. Board certified anesthesiologists provide this service as a regular part of the pediatric care. Pediatric nurses help the transition for parents and child in the induction and recovery process.

In adult patients, PSRT is used to treat:

  • Base of skull tumors such as Chordoma and Chondrosarcoma
  • Bone and soft tissue sarcomas including sacral, spinal and paraspinal sarcomas
  • Nasopharyngeal and Paranasal Sinus Carcinoma
  • Prostate Adenocarcinoma
