Prevalence of complementary/alternative medicines (CAMs) in a cancer population in northern Italy receiving antineoplastic treatments and relationship with quality of life and psychometric features.

PURPOSE: To explore the use of CAM (Complementary/Alternative Medicine) in a population of cancer patients undergoing antineoplastic therapy, and to compare differences in sociodemographics, quality of life, and psychological features between CAM users and non-users. METHODS: The study population was consecutive cancer patients undergoing antineoplastic treatment in three Piedmont cancer centers. Data were collected from anonymous questionnaires investigating CAM use or not, and what type if used, and sociodemographics, and through validated psychometric instruments to assess psychological features: Functional Assessment of Cancer Therapy-General, the Hospital Anxiety and Depression Scale, and the Mini Mental Adjustment to Cancer Scale. RESULTS: Of the 288 evaluable patients, 52 (18.1%) reported using one or more types of CAM; the most often cited were herbs, special diets and body-based practices, such as plantar reflexology, chiropractic application, and massage. On quality of life assessment, CAM users scored lower than CAM non-users for physical wellbeing (P = 0.006); no significant differences emerged for anxiety and depression and coping styles. CONCLUSIONS: CAM use is less prevalent in northern Italy than in most other European countries. CAM users were found to have a lower quality of life than CAM non-users.

Restless legs syndrome and its relationship with anxiety, depression, and quality of life in cancer patients undergoing chemotherapy.

OBJECTIVE: Restless legs syndrome (RLS) is a common sensorimotor disorder characterized by uncomfortable and unpleasant sensations in the legs that are relieved by movement. This study evaluated the prevalence of RLS in a consecutive series of cancer patients during chemotherapy and examined the relationship between presence of RLS and quality of life, anxiety, and depressive symptoms in these patients. METHODS: RLS was assessed according to the International RLS Study Group essential diagnostic criteria in two stages: a screening questionnaire first, followed by a sleep specialist-conducted structured diagnostic interview. The following questionnaires were administered: Functional Assessment of Cancer Therapy-General (FACT-G) for Quality-of-life (QoL) assessment; Hospital Anxiety and Depression Scale (HADS) to evaluate the levels of anxiety and depression; and Mini Mental Adjustment to Cancer Scale (Mini-MAC) to assess coping styles. RESULTS: A total of 257 patients were evaluated. Among them 56 were identified by the screening questionnaire to meet the criteria for RLS and 47 of whom were confirmed as affected by RLS after a structured interview, rendering a prevalence rate of 18.3%. RLS was significantly more frequent in women than men (23.7 vs. 11.8%; P = 0.01), and in patients receiving antineoplastic therapies for more than 3 months than their counterpart (21.8 vs. 10.8%; P = 0.03). Compared with those without RLS, patients with RLS had higher levels of anxiety (P = 0.0009) and depression (P = 0.001) and lower quality of life (P = 0.006). Sex-chemotherapy-duration-adjusted odds ratios of anxiety and physical well-being associated with RLS were 1.1 (95% CI 1.00-1.19; P = 0.04) and 0.7 (95% CI 0.43-1.01; P = 0.04), respectively. CONCLUSIONS: The prevalence of RLS in cancer patients undergoing chemotherapy is 18.3%, about double of that expected in the general population. The occurrence of RLS is much more frequent in female patients and with longer-term chemotherapy. Cancer patients afflicted by RLS have significantly higher levels of anxiety and depression, and poorer quality of life especially in the physical well-being dimension. Recognition and treatment of RLS in cancer patients is an important target in clinical management and may improve quality of life and overall health outcomes in these patients.
