Brain Cancer Radiation Therapy Can Effect Memory and Learning

Written by Administrator   

Cancer patients with tumors that have spread to the brain (brain metastases) who undergo stereotactic radiosurgery (SRS) and whole brain radiation have more than double the risk of developing learning and memory problems, compared to those who only have stereotactic radiosurgery, according to a randomized study presented September 22, 2008, at the American Society for Therapeutic Radiology and Oncology's 50th Annual Meeting in Boston.

“Results of this study show that initial stereotactic radiosurgery alone, coupled with close observation, could become the standard of care for patients newly diagnosed with brain metastases to best preserve their neurocognitive function,” Eric L. Chang, M.D., lead author of the study and a radiation oncologist at M.D. Anderson Cancer Center in Houston, said. “Results of this study could change the practice of how brain metastases are managed in the United States.”

Stereotactic radiosurgery is a specialized type of external beam radiation therapy that pinpoints high doses of radiation directly on the cancer in a shorter amount of time than traditional treatments (one day, instead of several weeks). Whole brain radiation therapy treats the visible lumps of the cancer and the invisible tumor deposits that are so small they may not be seen on even a sensitive imaging test. Therefore, the entire brain is treated to try to stop the spread of the tumors.

The study involved 58 patients who were newly diagnosed with one, two or three brain metastases and were randomized to receive stereotactic radiosurgery combined with whole brain radiation or stereotactic radiosurgery alone from January 2001 to September 2007.

The trial was halted after interim results showed that patients who received both stereotactic radiosurgery and whole brain radiation had a 49 percent decline in learning and memory functioning at four months, compared to patients who underwent stereotactic radiosurgery alone and who experienced a 23 percent decline in neurocognitive functioning. Neurocognitive outcome was measured by the ability of patients to immediately recall a list of 12 words after three attempts. For patients who received initial whole brain irradiation, nearly half of the patients lost the ability to recall five words from the same list over three attempts, compared to before they received the treatment.

The abstract, “Phase III Randomized Clinical Trial of Radiosurgery with or without Whole Brain Irradiation in Patients Newly Diagnosed with 1 to 3 Brain Metastases,” was presented at the American Society for Therapeutic Radiology and Oncology's 50th Annual Meeting in Boston.

Three Week Radiation Therapy as Effective as Five Weeks for Early-stage Breast Cancer

Written by Administrator   

Early-stage breast cancer patients who receive a more intensive course of radiation to their whole breast over three weeks is as effective as the standard, less intensive five-week whole breast radiation and offers patients more convenience at a lower cost, thereby providing a better quality of life, according to a randomized, long-term study presented September 22, 2008, in the plenary session at the American Society for Therapeutic Radiology and Oncology's 50th Annual Meeting in Boston.

The cost of this shorter treatment, called accelerated hypofractionated whole breast irradiation, is two-thirds of the cost of the standard whole breast radiation. It is also less expensive then other new approaches such as partial breast irradiation.

"There has been renewed interest in hypofractioned whole breast irradiation, due to the potential radiation advantages, patient convenience, quality of life and lower costs. However, long-term effects were a potential concern," Timothy Whelan, M.D., lead author of the study and a radiation oncologist at the Juravinski Cancer Centre at McMaster University in Hamilton, Ontario, Canada, said. "We were surprised that the risk of local recurrence and side effects for women treated with accelerated whole breast irradiation was so low even at 12 years. Our study shows that this treatment should be offered to select women treated with early-stage breast cancer."

Many women with early-stage breast cancer are able to undergo breast conserving therapy to keep their breast after treatment. Typically, this means they first have surgery to remove the cancer (called a lumpectomy) followed by a course of radiation therapy to kill any cancer cells that may remain. The standard whole breast radiation therapy treatment takes approximately 15 minutes every day, Monday through Friday, for five weeks.

Between April 1993 and September 1996, researchers randomly assigned 1,234 women to be treated with either accelerated whole breast irradiation or standard whole breast irradiation. These women were followed for 12 years to determine if accelerated whole breast radiation was as effective as the standard breast cancer treatment. At 10 years after treatment, breast cancer returned locally in 6.2 percent of breast cancer patients treated with the accelerated radiation therapy, compared to 6.7 percent for those patients treated with standard therapy. Both groups of patients also had a good or excellent cosmetic outcome from the radiation treatments.

"This shorter treatment may not be for everyone, however, I would encourage women whose breast cancer is caught early to talk to their oncologist to see if they are a good candidate for this shorter therapy," Dr. Whelan added.
