COVID-19 Update: Learn how New York Proton Center is taking all the necessary precautions to keep you safe.

Proton therapy for sarcomas

Sarcomas can occur in parts of the body—head and neck, pelvis, extremities, and spine, for example.  Oftentimes, it is difficult or not safe to give a high enough dose of radiation to effectively control these tumors with conventional radiation therapy.


Proton therapy, on the other hand, can direct a high dose of radiation to the tumor with minimal impact on healthy surrounding organs and tissues. This is especially helpful for sarcomas, and in patients who have had their cancer recur after prior radiation therapy.


Sarcomas we treat with proton radiation therapy include

  • Angiosarcoma
  • Chondrosarcoma
  • Epithelioid sarcoma
  • Ewing’s sarcoma
  • Fibrosarcoma
  • Gastrointestinal stromal tumor
  • Leiomyosarcoma
  • Liposarcoma
  • Malignant peripheral nerve sheath tumor
  • Osteosarcoma
  • Pleomorphic sarcoma
  • Rhabdomyosarcoma
  • Synovial sarcoma
  • Other sarcomas
Patients at the New York Proton Center receive Pencil Beam Scanning, a highly sophisticated and most precise type of proton therapy. As the name implies, proton Pencil Beam Scanning uses an extremely narrow beam to “dot” the protons onto the tumor. The process is repeated, layer by layer, like paint applied by the tip of an incredibly fine brush.

Not all proton therapy is created equal

Most proton centers use “volumetric” beams that deliver a fixed quantity of energy to the entire tumor. But the pencil beam scanning technology at the New York Proton Center delivers “intensity-modulated proton therapy,” or IMPT.


Widely considered the most advanced form of proton therapy, IMPT can target different parts of the tumor with different radiation dose levels based on the prescription and tumor’s exact location, while better protecting the surrounding normal tissues from irradiation. That’s particularly valuable when treating the most complicated tumors, those residing in the fissures of the head, neck and skull base.
