Complementary-alternative medicine among cancer patients in the western region of Turkey.

Purpose: To investigate the complementary/alternative medicine (CAM) applications and factors affecting its use among cancer patients in the western region of Turkey.

Patients And Methods: Face-to-face interview technique was used. Patients were asked to answer a questionnaire about their socio-demographic features, their level of knowledge about the disease and CAM application features.

Results: 220 adult cancer patients (79 male) were evaluated. Ninety-three (42.3%) were using at least one CAM method, the most common being herbal products which were preferred by 81 (36.3%) patients. Stinging nettle (Urtica dioica) was the most commonly used herbal product. Next was nutritional support, preferred by 45 (20.3%) patients. Eighty- nine (44.5%) of 200 patients who knew the diagnosis and 4 of 20 (20%) who did not were using CAM. In the patient group with awareness of the diagnosis, CAM application was significantly higher (p=0.034). CAM applications were detected in 34 of 70 (48.5%) patients with recurrent disease while 54 of 150 (36%) patients without recurrent disease were using CAM. The CAM applications were significantly higher in the group with recurrent disease (p=0.006). Fifty-three of 103 (51.4%) patients who had advanced disease were using CAM, while only 40 of 117 (34.1%) patients with local or locally advanced disease were using it. CAM applications were significantly higher in the group with advanced disease (p=0.030). Besides, knowing the diagnosis and disease recurrence were also independent risk factors for CAM usage [odds ratio (OR(: 3.1; 95% confidence interval (CI): 1.0-9.8 and OR: 2.2; 95% CI: 1.2-4.0 respectively]. As a result, nearly half of the patients (42.3%) in this region were using at least one of the CAM methods.

Conclusion: The severity of the disease (recurrence and dissemination) and patients' awareness of the diagnosis were the most important factors affecting the CAM applications.
