Effectiveness of a Global Multidisciplinary Supportive and Educational Intervention in Thermal Resort on Anthropometric and Biological Parameters, and the Disease-Free Survival after Breast Cancer Treatment Completion (PACThe)

International audienceA growing knowledge highlights the strong benefit of regular physical activity in the management of breast cancer patients, but few studies have considered biological parameters in their outcomes. In the prospective randomised trial after breast cancer treatment completion "PACThe," we determined the effects of physical activity and nutritional intervention on the biological and anthropometric status of patients after one year of follow-up, and clarified the link between biomarkers at allocation and disease-free survival. 113 patients from the population of the "PACThe" study (n = 251) were analysed for biological parameters. Patients were randomized after chemotherapy in two arms: the intervention "SPA" receiving a 2-week session of physical training, dietary education, and physiotherapy (n = 57), and the control "CTR" (n = 56). Diet questionnaire, anthropometric measures, and blood parameters were determined at allocation and one year later. Survival and recurrence were checked over 7 years. Data were considered as a function of BMI, i.e., ≤25 for normal, 25-30 for overweight, and >30 for obese patients. At allocation, the large standard deviation for nutrient-intake values reflected an unbalanced diet for some patients in the three groups. At one-year follow-up, we noticed an increase in glucose (p 30 groups. Using the Cox model, we demonstrated that the highest testosterone plasma values were linked to an increase of the recurrence risk (HR [CI-95%] = 5.06 [1.66-15.41]; p=0.004). One-year after a global multidisciplinary supportive and educational intervention, we found few anthropometric and biological changes, mainly related to the patient's initial BMI. We highlighted the importance of plasma testosterone in the evaluation of patient's recurrence risk. Future studies would help better understand the mechanisms by which such multidisciplinary interventions could interact with breast cancer recurrence and define the most effective modalities

Improvement in adherence to Capecitabine and Lapatinib by way of a therapeutic education program

International audienceA patient non-adherence with oral anticancer agents is a well-recognized barrier to effective treatment. The aim of this prospective study was to evaluate the efficacy of a therapeutic education program among non-adherent patients treated with Capecitabine alone or associated with Lapatinib

Long-term improvement of breast cancer survivors’ quality of life by a 2-week group physical and educational intervention: 5-year update of the ‘PACThe’ trial

The trial was financed by AFRETH (French association for hydrothermal research). Auvergne Regional Council, Clermont-Communauté, League Against Cancer (Puy de Dôme committee CD63).International audienceBackground: The advantages of adapted physical activity and nutritional education (APANE) on breast cancer prognosis and quality of life (QoL) are well known, but long-term results are lacking.Methods: A randomised controlled trial testing a 2-week intervention in hydrothermal centres including APANE enrolled 251 patients ost-chemotherapy. QoL and weight control were significantly improved at 12 months. A 5-year follow-up was performed to evaluate the persistence of improvements.Results: QoL increase (SF36) was persistent: effect-size at 2, 3, 4 and 5 years equalled respectively 0.27 (-0.01; 0.56), 0.28 (-0.02; 0.58),0.41 (0.02; 0.81) and 0.45 (0.11; 0.80).Weight control observed after intervention lasted 2 years: 2.7% decrease at 1 year (P=0.0085), 2.5%at 2 years (P=0.025); and respectively for waist -2.4% (-3.6; -1.1) (P=0.000014) and -1.3% (-2.5; -0.1) (P=0.0072).Conclusions: A 2-week intervention in hydrothermal centres performed shortly after chemotherapy can durably improve breast cancer patients’ QoL and reduce weight
