Cancer treatment center at Methodist Le Bonheur Germantown Hospital.
Methodist Germantown Radiation Oncology Center offers cancer treatment with External Beam Radiation Therapy:
- Intensity-modulated radiation therapy
- Image-guided radiation therapy
- Volumetric modulated arc therapy
Pre-treatment instructions will be given at the time of initial consultation.
Conventional Radiation - Conventional external beam radiation therapy is delivered via two-dimensional beams using a linear accelerator. This therapy mainly consists of a single beam of radiation delivered to the patient from several directions: often front or back, and both sides.
IMRT - Intensity-modulated radiation therapy (IMRT) is an advanced type of high-precision radiation that improves the ability to conform the treatment volume to concave tumor shapes, for example when the tumor is wrapped around a vulnerable structure such as the spinal cord or a major organ or blood vessel.
IGRT - Image-guided radiation therapy (IGRT) is the process of frequent two and three-dimensional imaging used to direct the radiation beam utilizing the imaging coordinates of the actual radiation treatment plan. The patient and tumor volume is localized in the treatment room guided by specialized imaging tests, such as CT scans, ultrasound or X-rays. This is very useful since tumors can move between treatments due to differences in organ filling or movements while breathing.
VMAT - Volumetric Modulated Arc Therapy (VMAT) precisely conforms the radiation to the cancer. This form of radiation therapy allows the radiation oncologist to spare more surrounding healthy tissue and better avoid nearby critical anatomy. During VMAT treatment, the radiation machine rotates around the patient in single or a series of arcs delivering focused beams of radiation to the cancer. The shape and intensity of the radiation beams changes as the machine rotates. These features mean that, in effect, the beam of radiation can come from an infinite number of angles, thereby reducing the dose of radiation to normal tissue while increasing the dose to the cancer. VMAT cuts radiation treatment times by one-half to two-thirds through delivering a higher and more targeted dose to cancerous tumors, without compromising patient safety.
Stereotactic Body Radiation Therapy is not currently offered, but will be in the near future.
