Robotic Surgery Device Adds Options for Cancer

Dr. Raj Dahiya serves as a radiation oncologist at Premier Cancer Centers in Dallas, Texas. Dr. Raj Dahiya’s organization was one of the first to install the CyberKnife M6 robot and the TomoTherapy H Series in the world. These technologies can serve as an alternative to cancer surgery.

Rather than cutting into a patient, the robotic CyberKnife system treats cancerous and benign tumors with doses of stereotactic radiation, which focus in three dimensions on the target. The pain-free system can be used anywhere in the body, especially the pancreas, liver, brain, and kidney. Although it employs high radiation doses, CyberKnife affects only the tumor, avoiding healthy tissue. It has been used for persons with multiple tumors or inoperable tumors, as well as for patients who simply wish to avoid invasive surgery.

Another unique feature of the CyberKnife is its ability to track and adjust dosages. This enables patients to lie down comfortably without worrying about their motions. Brain surgery with CyberKnife does not require the head restraints that other imaging systems do.

Preparation for the procedure involves a CT scan to locate the general area of tumors. Images from the scan are fed into CyberKnife’s software. This permits the radiologist to plan treatment.

Each procedure lasts between 30 and 90 minutes.
