Results from the largest study of men with prostate cancer treated with high-dose, intensity modulated radiation (IMRT) show that 89 percent of men were disease free eight years later. Patients were treated at Memorial Sloan-Kettering Cancer Center and classified into prognostic risk groups. After an average of eight years, 89 percent of the men in the favorable risk group were disease-free and none of the men in any group developed secondary cancers as a result of the radiation treatments.This report, published in the October 2006 issue of The Journal of Urology, is the first description of long term outcomes for prostate cancer patients using IMRT. Intensity modulated radiation is an improved form of three-dimensional conformal radiation (3D-CRT). IMRT uses enhanced planning treatment software that more precisely targets the prostate, allowing the beam of radiation to deliver a high dose to the tumor target while sparing the adjacent bladder and rectum from exposure to the higher amounts of radiation.

Dr. Michael J. Zelefsky, Chief of the Brachytherapy Service at Memorial Sloan-Kettering, said “This study confirms that we can improve patients’ quality of life by reducing the side effects of radiotherapy while maintaining disease-free survival.”

Rosemont Mayor Donald E. Stephens is one of the nation’s longest-serving mayors. Stephens, 78, announced on Thursday, that he has undergone surgery for stomach cancer and hopes to return to work soon. Doctors operated on Stephens in May at Advocate Lutheran General Hospital in Park Ridge.

The northwest suburban mayor said he finished radiation treatments about two weeks ago and anticipates a full recovery. Stephens’s condition has been kept as a secret. He has had a series of health issues in the last nine months. Last December, he underwent triple-bypass surgery. In May, he missed his village’s 50th anniversary gala because of another health problem before his cancer surgery.

“I’m tired. The radiation knocks the socks out of you,” Stephens said. “Other than that, I’m doing just fine.” “I just didn’t want all this sympathy,” Stephens explained when asked why his condition was kept secret.
