Cancer survivor Joan Harris chronicled her recovery in "My Story," a booklet that has raised substantial contributions for the Kenton Ward for terminally ill children at St. Bartholomew's Hospital in London. According to Mrs. Harris, the experience has resulted in permanently changing her outlook on life and people. "I no longer worry over trivial things, because I have found that with just a little patience and faith, little problems always seem to solve themselves in the end."* *From "My Story" by Joan Harris Varian's RPM Respiratory Gating System adds a new level of precision to radiation therapies. It controls dose delivery to compensate for tumor motion caused by breathing. This has potential in treatment of tumors in lungs and other areas affected by respiratory motion. |
"You have to trust your cancer team," says Joan Harris, who fought and won her battle against cancer - first in her breast and then later in her head, requiring radiation treatment of brain
and lung tumors. "I was very, very fortunate to have established an excellent personal relationship with
everyone at the cancer treatment center at St. Bartholomew's Hospital. When you are ill with cancer, you put your hope in
these people." Head and neck cancers represent 20% of all cancers diagnosed today. Tumors can be located close to the spinal cord, optic nerves, and the brain and may be very difficult to treat. Radiation delivered outside the target area risks damaging these critical structures or other surrounding tissues.
"IMRT can afford a significant reduction in radiation dose to the parotid gland and the spinal cord, or allow a higher, more effective radiation dose to be delivered to the tumor," Dr. Nutting says. "If these higher doses can be delivered more safely, we can expect both increased survival and reduced side effects for groups of cancer patients. The Varian IMRT system integrates treatment planning with the Helios radiotherapy inverse planning program and dynamic MLC delivery." With the placement of IMRT systems at St. Bartholomew's and other hospitals, the United Kingdom is among the nations leading Europe in improving radiation cancer therapy. Following the World Health Organization's guidelines for radiotherapy, the U.K. Department of the Treasury has announced the purchase of 45 linear accelerators for cancer care. In addition, the New Opportunities Fund, for projects not directly funded by the government, will sponsor another 56 new linear accelerators in the U.K. These linear accelerators will upgrade cancer care in more than 60 treatment centers in England. Many other European centers including Amsterdam, Holland; Bern, Switzerland; and Leuven, Belgium are also modernizing systems for state-of-the-art cancer care. |
