People who choose alternative medicine as their sole treatment for curable cancers have a higher risk of dying early, researchers say.

THURSDAY, Aug. 17, 2017 (HealthDay News) -- People who choose alternative medicine over traditional cancer treatments for curable cancers have a higher risk of dying early, researchers report.

"We now have evidence to suggest that using alternative medicine in place of proven cancer therapies results in worse survival," said study lead author Dr. Skyler Johnson from Yale School of Medicine and Yale Cancer Center.

"It is our hope that this information can be used by patients and physicians when discussing the impact of cancer treatment decisions on survival," Johnson said in a school news release.

Steve Jobs, co-founder and former CEO of Apple, is likely the most famous person who initially chose alternative medicine as a sole treatment. He eventually turned back to conventional medicine when the alternative medicine treatment didn't keep his pancreatic cancer at bay. But at that point, the cancer had advanced beyond the point when it was curable, according to published reports.

The authors behind the new study said there has been little research into how effective alternative medicine may be as a cancer treatment.

"We became interested in this topic after seeing too many patients present in our clinics with advanced cancers that were treated with ineffective and unproven alternative therapies alone," said senior author Dr. James Yu. He's an associate professor of therapeutic radiology at Yale Cancer Center.

The study included 840 patients with breast, prostate, lung and colon cancers. They were part of a national database that has information on people newly diagnosed with cancer in the United States.

The researchers compared 280 patients who chose alternative medicine alone to 560 patients who underwent conventional cancer treatment. The researchers followed the patients from 2004 to 2013.

Those patients who received alternative therapy instead of the usual treatments -- chemotherapy, surgery, radiation, or some combination of these -- were more likely to die during the study, the researchers found.

Study co-author Dr. Cary Gross is a professor of medicine and epidemiology at Yale School of Medicine. "It's important to note that when it comes to alternative cancer therapies, there is just so little known -- patients are making decisions in the dark," he said.

"We need to understand more about which treatments are effective, whether we're talking about a new type of immunotherapy or a high-dose vitamin, and which ones aren't, so that patients can make informed decisions," Gross said.

The study was published online recently in the Journal of the National Cancer Institute.
