Many patients receive radiation therapy - a high-energy X-ray - to slow, stop or destroy cancer cells so they are unable to grow and multiply. It can be used for delicate locations such as the vocal cords and to control early cancers without surgery. It can also be used to shrink a tumor before surgery or after surgery to destroy any remaining cancer cells in the area. It is frequently used in conjunction with chemotherapy to make both forms of treatment more effective. The goal of radiation treatment of tumors is to deliver a lethal dose of radiation to the tumor while sparing nearby healthy structures. After the completion of the treatment, most patients can resume their daily normal life.

Intensity Modulated Radiation Therapy (IMRT)

CRMC is the only medical facility in Jefferson City to offer Intensity Modulated Radiation Therapy (IMRT). In fact, this ultra-sophisticated technique is only offered by 36 percent of the radiation therapy programs in the United States. This new technology allows radiation oncologists to match the radiation dose to the shape and location of the tumor, thus avoiding damage to the surrounding healthy tissue and organs. According to "The Oncologist Online," IMRT holds the promise in radiation oncology in the new century.

Advantages of IMRT:

  • Improves cancer cure rates
  • Reduces the side effects of treatment
  • Protects surrounding normal tissue in vital areas (neck, head and prostate)
  • Increases five-year cure rate in prostate cancer by 22-40 percent
  • Decreases long-term bowel side effect in prostate cancer by 19 percent

Radiofrequency Ablation (RFA)

RFA is a minimally invasive procedure, used in conjunction with chemotherapy, in which the interventional radiologist places a slender probe directly into the tumor. This ensures that treatment will focus on the diseased area. Once the probe is in position, a bouquet of very thin, flexible electrodes are extended from the end of the probe into the tissue. Using a radiofrequency generator, the physician then allows a carefully controlled amount of energy to flow through the electrodes into the tissue. When all cells within the lesion, as well as a margin around it, are heated for a predetermined length of time, the procedure is complete. This results in a reduction of the size or elimination of the tumor. RFA can be considered as a treatment option for most patients with liver cancer, colorectal cancer and bone metastases.
