Efficacy of a physiotherapy, yoga and patient education programme for patients with breast cancer and hormone therapy-induced pain: a multicentre randomised study protocol (SKYPE 2)

Introduction Osteoarticular pain is experienced by approximately 50% of patients with breast cancer under hormone therapy and can increase the risk of therapy discontinuation. Among complementary therapies, yoga has shown efficacy regarding reduction of fatigue, anxiety, pain due to hormone therapy and inflammation. Personalised patient education programmes increase engagement and motivation, and induce effective behavioural changes. The SKYPE programme, an integrated intervention combining physiotherapy, yoga and patient education, showed promising efficacy on hormone therapy-induced pain in a previous pilot study. In this study, we hypothesised that using theory-based patient education favour learning and practising 15 min of at-home yoga every day to decrease hormone therapy-induced pain.Methods and analysis This multicentre randomised study will assess the efficacy of the SKYPE programme on pain reduction compared with standard care in patients with breast cancer reporting osteoarticular pain due to hormone therapy. Main secondary objectives will describe pain evolution and characteristics, patient adhesion to yoga sessions and home practice, forward flexibility, quality of life, fatigue, anxiety and compliance to hormone therapy. Patients in the intervention group will participate in 1 weekly educational yoga session of 90 min for 6 weeks, supervised by physiotherapists (period 1). They will also perform daily at-home 15 min yoga sessions for 12 weeks, the total duration of the intervention (periods 1 and 2). Pain will be evaluated during physiotherapy check-ups at baseline (T0), at 6 weeks (T1) and at 12 weeks (T2).Ethics and dissemination This study was approved by the ethics committee (CPP Ile de France 8 on 22 June 2020). The results will be disseminated to patients and healthcare professionals, and published in a peer-reviewed journal.Trial registration number NCT04457895

Importance of Patient Education for At-home Yoga Practice in Women With Hormonal Therapy-induced Pain During Adjuvant Breast Cancer Treatment: A Feasibility Study

International audienceBackground Osteo-articular pain (OAP) is experienced by approximately 50% of women under hormonal therapy (HT) for breast cancer (BC), which increases the risk for therapy discontinuation. This study was aimed to assess benefits of yoga practice combined with patient education (PE) for at-home practice by evaluating feasibility among BC patients under HT and measuring OAP, flexibility and satisfaction.Methods Feasibility was evaluated by patient adherence as accomplishment of at least 4 out of 6 supervised yoga-PE sessions along with 70% or more at-home yoga sessions. Intervention (12 weeks) included two 6-weeks periods: P1 comprising one 90-minutes supervised yoga-PE session/week and 15-minutes daily at-home yoga and P2, daily autonomous at-home yoga sessions. Evaluations (at inclusion and by the end of each period) consisted in assessment of OAP on Visual Analog Scale (VAS), forward flexibility (cm) and patient satisfaction on Likert (0-10 points) scale.Results Between September 2018 and May 2019 we included 24 patients of median 53 years (range 36-72). Feasibility was validated by 83% successful adherence rate. Pain was significantly reduced from median VAS of 6 [range 4-10] to 4 [range 0-7] at the end of both P1 and P2 ( p < 0.01), albeit with no difference between P1 and P2. Forward flexibility improved by a median gain of 8 cm (end of P2) and median satisfaction score of 10/10 [range 8-10].Conclusion Combined physiotherapy-yoga-PE intervention is a feasible strategy to increase at-home yoga practice with potential benefit on pain, flexibility, and satisfaction, thus prompting further evaluations in larger randomized multicenter trials.ClinicalTrials.gov NCT0400175

Impact of Complementary Medicines on Survival in Patients with Cancer Treated with Oral Chemotherapy in an Oncology Hospital in France: Exploratory StudyImpact des Thérapies Complémentaires sur la Survie de Patients Atteints d’un Cancer Traités par Chimiothérapie Orale dans un Établissement Hospitalier Français Spécialisé en Oncologie : Étude Exploratoire

International audienceA retrospective observational study carried out in the United States showed a decrease in survival in patients treated for breast, prostate, lung and colorectal cancer with complementary medicines. We verified this result with a French population of consecutive 636 patients diagnosed with the same cancer and treated with oral chemotherapy in an hospital for three years. An interview by a pharmacist before the administration of oral chemotherapy was made to identify the complementary medicines used by the patients. We compared the overall survival using a log-rank test by stratifying the groups (number of cancers, number of comorbidities, age, sex). The results show no significant difference in survival between the group of 191 patients declaring that they use complementary medicines and the group of 445 patients declaring that they do not use (p = 0.126). A descriptive analysis of the 256 mentioned complementary medicines suggests that French patients use non-pharmacological interventions to alleviate cancer-associated symptoms and side effects of antineoplastic treatments, and not alternative medicine prompting patients to refuse conventional treatments compared to United States
