Tomotherapy represents a new generation in image-guided radiation treatment.

Radiation therapy plays an important role in the treatment of many cancers.

The Radiation Oncology Clinic at UC Davis Cancer Center is among the best-equipped in the nation, with the region's most highly trained and experienced specialists.

It also has a large clinical trials network, offering patients access to new therapies that often aren't widely available.

At any given time, more than a dozen adult clinical trials of new radiation therapy approaches are under way in the Department of Radiation Oncology. The trials are conducted through the Radiation Therapy Oncology Group, a national cancer study research group funded by the National Cancer Institute. The group, which has nearly 30 years of experience in running clinical trials, is made up of 250 major cancer research institutions in the United States and Canada, including UC Davis Cancer Center.

Services and procedures at the Radiation Oncology Clinic include:

  • State-of-the-art linear accelerators

  • Multidisciplinary treatment that combines radiation with surgery and chemotherapy

  • Three-dimensional conformal radiation therapy (3-D CRT) combining digital diagnostic imaging, powerful computers and specialized software to tailor or "conform" the radiation beam to the shape of the tumor

  • Intensity-modulated radiation therapy (IMRT), the latest advance in 3-D CRT, permitting delivery of high-dose radiation to a tumor while minimizing dose to other tissues

  • Brachytherapy, in which tiny radioactive "seeds" are implanted to treat prostate cancer

  • High-dose rate brachytherapy, which delivers radiation to the prostate without implants

  • Stereotactic radiosurgery, which uses precisely focused radiation to treat tumors and other abnormal growths in the brain, without any incision

  • Radioimmunotherapy, using monoclonal antibodies that deliver radioactive isotopes directly to tumor cells

  • Radioactive plaques for ocular melanoma

  • Whole-body radiation in conjunction with the bone marrow transplant program.
