ORLANDO, Fla. Breast cancer survivors with poor physical health scores had an elevated risk of poorer cancer outcomes, including recurrence and death, according to the results of an observational study presented at the AACR 102nd Annual Meeting 2011, held April 2-6.
Survivors of breast cancer who had poor health scores were 27 percent more likely to experience either a recurrence of their cancer or a new breast cancer. Physical health also impacted survival quite strongly; risk of death from any cause was 65 percent greater among those with poorer health scores.
Researchers from UC San Diego Moores Cancer Center used data from three of the four cohorts included in the After Breast Cancer (ABC) Pooling Project to analyze the association of poor physical health and survival, along with a cluster of comorbidities. The physical health score has been shown in smaller studies to be an important predictor of future breast cancer events and overall survival in women with breast cancer.
"Here we see a single metric that predicts risk," said John P. Pierce, Ph.D., who is the Sam M. Walton professor for cancer prevention and associate director for population sciences at Moores Cancer Center. "Variables cluster together and are summarized in the physical health score. The question becomes how to improve the physical health status of this particular group of breast cancer survivors."
Physical health scores were measured for a total of 9,387 early-stage breast cancer survivors, using the SF-36 a multipurpose, short-form health survey taken after diagnosis, with follow-up occurring on average seven years later. The physical health score includes information about how an individual perceives their own physical functioning, bodily pain and limitations caused by physical problems.
About half the women in the sample had a physical health score that met the survey definition of poor physical health. Low physical health scores were
