IntroductionCancer-related impairments often co-occur with bodily disturbances. Body psychotherapy (BPT) can improve bodily wellbeing, yet evidence in cancer survivors is scarce. Hence, we aimed to evaluate whether blended group BPT alleviates bodily disturbances in post-treatment cancer patients.MethodsWe conducted a bi-center study (registered in ClinicalTrials.gov, under No. NCT03707548), applying a pre-post convergent parallel design of weekly group BPT interspersed with smartphone-based ambulatory interventions using a waiting-period comparator. We included patients with completed curatively intended treatment for malignant neoplasms, suffering from bodily disturbances. The primary outcome was body image disturbances. Secondary outcomes were experiencing and appreciating body awareness, mental wellbeing, and health-related quality of life.ResultsForty patients (mean age 51.7 years) attended group BPT. Mixed-effect linear regression models contrasting intervention with the waiting period did not show statistically significant differences regarding the primary outcome [Pre-post difference contrasts: 1.44, 95% confidence interval (CI): −1.51 to 4.93, p = 0.339]. However, patients showed greater improvements in appreciating body awareness, measured by the “Body Mindfulness Questionnaire” (BMQ), from pre- to post-intervention as compared to the waiting period (pre-post difference contrasts: 7.31 95% CI: 4.15–10.47, Bonferroni-Holm corrected q = 0.0002).DiscussionWe found no evidence that blended group BPT was effective in improving body image disturbances in post-treatment cancer patients, but found indications for an increase in body awareness appreciation.Clinical trial registrationClinicalTrials.gov, identifier NCT03707548.

基于团体的身体心理治疗提高了治疗后癌症患者对身体意识的认识：一项非随机临床试验

介绍癌症相关的损伤通常与身体障碍同时发生。身体心理治疗 (BPT) 可以改善身体健康，但癌症幸存者的证据很少。因此，我们的目的是评估混合组 BPT 是否能减轻治疗后癌症患者的身体不适。方法我们进行了一项双中心研究（注册于临床试验.gov, 在 No. NCT03707548 下），应用每周组 BPT 的前后收敛并行设计穿插使用等待期比较器的基于智能手机的门诊干预。我们纳入了已完成恶性肿瘤治愈性治疗、患有身体障碍的患者。主要结果是身体意象障碍。次要结果是体验和欣赏身体意识、心理健康和与健康相关的生活质量。结果40 名患者（平均年龄 51.7 岁）参加了团体 BPT。将干预与等待期进行对比的混合效应线性回归模型未显示关于主要结果的统计学显着差异[事前差异对比：1.44，95% 置信区间 (CI)：-1.51 至 4.93，p= 0.339]。然而，与等待期相比，从干预前到干预后，通过“身体正念问卷”(BMQ) 测量，患者在欣赏身体意识方面表现出更大的改善（前后差异对比：7.31 95% CI：4.15– 10.47，Bonferroni-Holm 更正q= 0.0002）。讨论我们没有发现混合组 BPT 可有效改善治疗后癌症患者的身体形象障碍的证据，但发现了身体意识欣赏增加的迹象。临床试验注册临床试验.gov, 标识符 NCT03707548。
