ABSTRACT
INTRODUCTION: Phase angle (PA), a parameter that is obtained from body composition analysis, is an indicator of cellular health status. A lower PA in cancer patients can lead to a decrease in functional status and quality of life (QoL) and increased mortality. Studies have shown that physical activity increases PA. In this study, we aimed to examine the effects of Hatha yoga on PA, body composition, and QoL in patients with breast cancer. METHODS: Thirty-one patients were randomized into the yoga (group 1, n = 15) and the control group (group 2, n = 16). Hatha yoga was practiced twice a week for 10 weeks in the intervention group. The PA of the patients was assessed using a body analysis instrument, and QoL was evaluated with an EORTC QLQ questionnaire both before treatment and at week 10. RESULTS: Group 1 had significant improvements in the posttreatment EORTC QLQ functional and global scores (p < 0.05). In group 2, a significant improvement was observed in the EORTC QLQ symptom subscale (p = 0.035). PA values did not show any improvements in both groups (p > 0.05). Comparison of the 2 groups revealed no differences. CONCLUSION: Yoga may have beneficial effects on QoL in patients with breast cancer but does not have a significant effect on PA. There is a need for further studies to make a definitive statement.

Background/aim: The purpose of this study was to determine sarcopenia, sarcopenic obesity and phase angle (PA) and the influence of chemotherapy (CT) on anthropometric measurements and and the PA in in geriatric patients with gastrointestinal (GI) cancer. Materials and methods: The anthropometric measurements, calf circumference (CC), upper midarm circumference (UMAC), and hand grip strength (HGS), have been measured to understand muscle function of 153 patients (mean age of 70.5 ± 5.6 years, 28.8% female, 71.2% male). Sarcopenia and PA measurements have been evaluated by bioelectrical impedance analyses. The same evaluations were checked again after 1 cycle of CT (min: 4, max: 6 weeks). Results: Patient population consisted of colorectal (51,6%), gastric (26.8%), pancreas (11.8%), liver (7.2%), and biliary tract cancer (2%). UMAC (28.5 ± 4.4 before, 28.1 ± 4.9, P = 0.034 after CT), and HGS measurements (27.5 ± 8.6 before, 26.8 ± 8.8 after CT, P = 0.007) have significantly decreased after CT. CC measurement < 31 cm at first visit was seen in 13.1% of patients, but the ratio raised to 20.3% after CT (χ², P = 0.003). Severe sarcopenia was determined in 33% of all patients, and 30.0% of them have been considered as sarcopenic obese. Conclusion: Sarcopenia and sarcopenic obesity were prevalent in this group patients. The CT caused a decrease in muscle functions, UMAC, and CC. Patients should be followed up carefully for sarcopenia, sarcopenic obesity, and nutritional aspect and it would be proper to intervene before sarcopenia has not occurred yet.
