The CyberKnife¢ç Robotic
Radiosurgery System is the world¡¯s first and only radiosurgery system designed to treat tumors anywhere in the body with
sub-millimeter accuracy. Using image guidance technology and computer controlled robotics, the CyberKnife System is designed
to continuously track the tumor, detect its location and correct for tumor and patient movement in real-time throughout
the treatment. Because of its extreme precision, the CyberKnife System does not require invasive head or body frames to
stabilize patient movement, vastly increasing the system¡¯s flexibility.
Unlike traditional radiosurgery systems that can only treat tumors in the head and neck, the CyberKnife System can treat both intracranial and extracranial tumors. In fact, extracranial treatments currently represent more than 50 percent of CyberKnife System procedures in the United States, including those of the spine, lung, prostate, liver and pancreas. The CyberKnife System provides an additional option to many patients diagnosed with previously inoperable or surgically complex tumors, or patients who may be looking for an alternative to surgery.

Intensity modulated radiation therapy (IMRT) is a specialized form of 3D-CRT that allows radiation to be more exactly
shaped to fit your tumor. With IMRT, the radiation beam can be broken up into many "beamlets," and the intensity of each
beamlet can be adjusted individually. Using IMRT, it may be possible to further limit the exact amount of radiation that
is received by normal tissues that are near the tumor. In some situations, this may also allow a higher dose of radiation
to be delivered to the tumor, increasing the chance of a cure.
Bexxar (tositumomab and iodine I 131 ) and Zevalin (Ibritumomab and Indium 111 or Yttrium 90) are radiolabled monoclonal antibodies for the treatment
of patients with CD20 positive, follicular, non-Hodgkin's lymphoma (NHL), with and without transformation, whose disease
is resistant to Rituximab and has relapsed following chemotherapy.
