Proton therapy for gynecologic cancers

Proton therapy is an important treatment option for many gynecologic tumors. It can deliver high-dose radiation to the tumor with less damage to critical organs in or near the pelvis, including the small bowel, large bowel, bladder, kidneys and pelvic bone marrow. This allows patients to experience fewer side effects and have better quality of life. Proton therapy also reduces the risk of infertility and other reproductive problems commonly associated with traditional radiation therapy.


Gynecologic cancers we treat with proton radiation treatment include

  • Cervical cancer
  • Endometrial/uterine cancer
  • Vaginal cancer
  • Vulvar cancer
  • Recurrent gynecologic cancers
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.
