Complementary therapies for cancer patients: assessing information use and needs

Many cancer patients seek complementary therapies (CTs) for cancer management; however, relatively little is known about patients’ CT information seeking behaviour. Therefore, we assessed: 1) cancer patients’ use of the types and sources of CT information; 2) their information preferences; and 3) their understanding of the phrase “scientific evidence or proof that a therapy works.” We collected data from 404 patients attending the Tom Baker Cancer Centre (TBCC) in Calgary and 303 patients calling the Cancer Information Service (CIS) helpline. In most cases, patients wanted information on the safety of CTs, how CTs work and their potential side effects. Physicians and conventional cancer centres were the most desired sources of CT information, but relatively few patients obtained information via these sources. Although patients were aware of the meaning of scientific evidence, they often used information based on non‑scientific evidence, such as patient testimonials. The creation of a supportive care environment in conventional cancer treatment centres, by providing CT information, may help address cancer patients’ concerns and alleviate some of the stress that may have been caused by the cancer diagnosis.
