Abstract

The use of Complementary and Alternative Medicine (CAM; 補充與替代醫學 bǔ chōng yǔ tì dài yī xué) has been rapidly increasing among cancer patients. However, this pervasiveness is still largely unexplored among Malaysian cancer patients. The current study aimed to evaluate the patterns of CAM use among cancer patients from a local hospital in Malaysia. In addition, the study focused on the information-seeking behavior and CAM use disclosure to doctors. Of 393 patients, 184 (46.1%) had used CAM for their cancers. CAM usage was significantly associated with gender (p = 0.021), level of education (p = 0.001), employment status (p = 0.02), and monthly income (p < 0.001). Among frequently used CAM were nutritional supplements (n = 77, 41.8%), natural products (n = 74, 40.2%), and multivitamin (n = 62, 33.6%). Friends and family members were the most common source of CAM information (n = 139, 75.5%). Seventy-nine (43%) reported to disclose their CAM use to the health care providers. The most common (n = 63, 34.2%) reason of nondisclosure was “it is not important to discuss it with oncologist.” This study confirmed that CAM use is common among Malaysian cancer patients, thus highlighting a greater need for patient education regarding CAM therapies and their potential interactions with conventional therapies. Although some types of CAM therapies may help patients to cope with emotional distress and improve quality of life, CAM, with no proven efficacy, may pose dangers to patients' health due to interactions with conventional therapies. Doctors and other health care providers including nurses and pharmacists should engage cancer patients in an open nonjudgmental dialog to ascertain CAM use disclosure to their health care providers.

1. Introduction

In Malaysia, use of Complementary and Alternative Medicine (CAM; 補充與替代醫學 bǔ chōng yǔ tì dài yī xué) for health maintenance, disease prevention and treatment is prevalent among healthy individuals as well as patients with chronic diseases.1 and 2 Particular to cancer, numerous studies reported a significantly high degree of CAM use among the Malaysian population.3 and 4 At the same time approximately 80% of the population in African and Asian countries reported CAM as a primary source to cure and prevent disease.5 The cumulative incidence rate of CAM use among cancer patients is in the wide range of 14.5–91%.6 and 7 The wide variation is often due to a lack of agreement on definition and dimensions of CAM.8 The National Centre of CAM defines CAM as “a group of diverse medical and healthcare systems, practices, and products that are not currently part of conventional medicine.”9 The use of CAM may be prompted by various factors that eventually direct cancer patients towards CAM. Emotional impact of cancer diagnosis, fear of side effects due to conventional therapies, lack of communication with doctors, and the need of personal control are among the factors associated with CAM use.10 and 11 Despite the fact that CAM is used by an increasing number of Malaysians, little information is available regarding the perceptions towards the effectiveness of CAM over conventional therapies, source of information, and disclosure of CAM to the health care providers. This cross-sectional study aimed to determine the use of CAM among cancer patients, sources from where CAM related information is retrieved and CAM disclosure to the health care providers. At the same time evaluating numerous traditional therapies specific to Malaysian culture would be valuable to inform future research priorities.
