(Reuters) - More than one in five women with early-stage breast cancer said they were given too much responsibility for treatment-related decisions - and those patients were more likely to end up regretting the choices they made, according to a U.S. study.
The findings, which appeared in the Journal of General Internal Medicine, don't mean that women should not be fully informed about their treatment options, researchers said, but rather that doctorsmay need to find new strategies to communicate with patients, especially the less educated.
"Some women may feel overwhelmed or burdened by treatment choices, particularly if they are not also given the tools to understand and weigh the benefits and harms of these choices," wrote research leader Jennifer Livaudais and colleagues.
Her team from the Mount Sinai School of Medicine in New York surveyed 368 women who had just had surgery for early-stage breast cancer at one of eight New York City hospitals, and again six months later.
The majority said they typically had trouble understanding medical information and less than one-third knew the possible benefits of surgery, radiation and chemotherapy, Livaudais and her colleagues found.
Lack of both "health literacy" and knowledge about treatment benefits was common among the 21 percent of women who said they had too much responsibility for decision-making - as well as among the seven percent who felt they didn't have enough responsibility.
Women who were poor, non-white or didn't finish high school were also more likely to feel that they had either too much or too little say in their treatment.
Close to two-thirds of women on both ends of the spectrum had some regret about their originaltreatment decisions six months down the line. That compared to one-third of women who originally said they had a "reasonable amount" of decision-making responsibility.
Steven Katz, who has studied cancer-related decision-making at the University of Michigan in Ann Arbor, said that compared to past years, doctors now have better ways to tailor treatment to individual patients. But that also means treatment options are based on more convoluted information.
"The treatments are linked in complicated ways, and the information that doctors draw on to make recommendations has increasingly become more and more complex" said Katz, who wasn't involved in the new study.
He said that for patients trying to make the best treatment choices, the smartest thing they can do is have a team of doctors - an experienced surgeon, a medical oncologist, a radiation oncologist and a plastic surgeon - all working on their case and sharing ideas.
"The purpose (of the study) was not to say women shouldn't be provided with these treatment options, but that the information really needs to be tailored better," said Livaudais, who is now at the University of California, San Francisco.
She recommended that doctors ask each patient how much responsibility she feels comfortable taking.
