IMRT for pancreatic cancer

What is IMRT?

Intensity modulated radiation therapy (IMRT) is a state-of-the-art radiation delivery system that is used to treat difficult-to-reach tumors.

How it works

IMRT uses advanced software to plan a precise dose of radiation, based on tumor size, shape and location. A computer-controlled device called a linear accelerator delivers radiation in sculpted doses that match the exact 3D geometrical shape of the tumor, including concave and complex shapes.

With IMRT, our radiation oncologist can adjust the intensity of radiation beams across the treatment area as needed with laser accuracy. This means we can deliver higher radiation doses than traditional radiation therapy methods, while minimizing exposure to healthy tissues.

Because of its greater degree of accuracy, IMRT may be a treatment option for patients who have reached the maximum allowable dose of conventional radiation therapy and have a recurrent tumor in the treated area.

IMRT for pancreatic cancer

If you have previously had radiation therapy for pancreatic cancer and are experiencing recurrent tumors in the treated area, IMRT may be an appropriate option for you.

Compared to standard radiotherapy, IMRT allows our radiation oncologists to use higher radiation doses than traditional therapies would allow in these areas. At the same time, IMRT helps to spare more of the surrounding healthy pancreatic tissue from harmful doses of radiation.

Two ways that IMRT differs from other radiation therapies for pancreatic cancer are as follows:

  • IMRT uses a powerful, advanced computer program to plan a precise dose of radiation in three dimensions, based on pancreatic tumor size, shape and location.
  • IMRT directs radiation at the pancreatic tumor, modulating the intensity of pencil-thin beams of radiation with laser accuracy. For some pancreatic cancer patients, IMRT replaces external beam treatments. In the majority of cases, however, IMRT is used in conjunction with, or after, another primary treatment.
