Variables related to health-related quality of life among breast cancer survivors after participation in an interdisciplinary treatment combining mindfulness and physiotherapy.

BACKGROUND: Breast cancer diagnosis and treatment increase the potential psychological impact on breast cancer survivors (BCS). The objective of this study was to assess the effects of an interdisciplinary intervention during follow-up in BCS and identify variables related to improvements in HRQoL. MATERIALS AND METHODS: In a non-randomised quasi-experimental design performed on an outpatient basis in a hospital gynaecology and oncology unit, 60 BCS were assigned to an interdisciplinary experimental group (EG) or a usual care group (CG). The EG underwent 12 sessions of an interdisciplinary program which included Mindfulness and physiotherapy, for 120 min per day, once a week for 6 weeks. At baseline, at 6 weeks and at 3 months after the intervention, participants of EG and CG completed an assessment of HRQoL (EuroQol and EORTC-QLQ-C30) and symptomatology of anxiety and depression. Additionally, EG completed an assessment of satisfaction with the treatment. For data analysis, we used descriptive statistics, Wilcoxon test, Kruskal-Wallis test, Chi-square and Fisher tests and generalised linear models. RESULTS: After 6 weeks, statistically significant differences were apparent in global and cancer-related health symptoms such as fatigue and pain in the EORTC QLQ-C30 and in anxiety and depression, among the EG (n = 30) compared with the CG (n = 30). Patients receiving the intervention reported a high degree of satisfaction with the treatment. Three months after the intervention, patients in the EG continued to show statistically significant improvements compared with the CG. In addition, allocation to the EG was identified as a variable related to improvement of HRQoL (EORTC QLQ-C30) in the multivariable model. CONCLUSIONS: The results of our study suggest that a 6-week interdisciplinary intervention may improve HRQoL and symptomatology of anxiety and depression in BCS patients at 3 months. The study presents data that the intervention for BCS appears promising and warrants further study in a randomised controlled trial.

Factors that Influence Treatment Delay for Patients with Breast Cancer.

INTRODUCTION: The diagnosis or treatment of breast cancer is sometimes delayed. A lengthy delay may have a negative psychological impact on patients. The aim of our study was to evaluate the sociodemographic, clinical and pathological factors associated with delay in the provision of surgical treatment for localised breast cancer, in a prospective cohort of patients. METHODS: This observational, prospective, multicentre study was conducted in ten hospitals belonging to the Spanish national public health system, located in four Autonomous Communities (regions). The study included 1236 patients, diagnosed through a screening programme or found to be symptomatic, between April 2013 and May 2015. The study variables analysed included each patient's personal history, care situation, tumour history and data on the surgical intervention, pathological anatomy, hospital admission and follow-up. Treatment delay was defined as more than 30 days elapsed between biopsy and surgery. RESULTS: Over half of the study population experienced surgical treatment delay. This delay was greater for patients with no formal education and among widows, persons not requiring assistance for usual activities, those experiencing anxiety or depression, those who had a high BMI or an above-average number of comorbidities, those who were symptomatic, who did not receive NMR spectroscopy, who presented a histology other than infiltrating ductal carcinoma or who had poorly differentiated carcinomas. CONCLUSIONS: Certain sociodemographic and clinical variables are associated with surgical treatment delay. This study identifies factors that influence surgical delays, highlighting the importance of preventing these factors and of raising awareness among the population at risk and among health personnel.

Overall breast density in MR mammography: diagnostic and therapeutic implications in breast cancer.

The objective of this study was to assess the efficacy of MR mammography (MRM) in evaluating breast cancer extent in women with fatty or dense breasts, and its contribution to the therapeutic approach. The authors reviewed 97 carcinomas detected in 93 women (both symptomatic and from screening) that were classified in two groups according to breast density pattern. Mammography, ultrasound (US), and MRM were performed to evaluate size, extension of the in situ component, presence of multifocal/multicentric disease, and contralateral involvement. Results obtained on mammography plus US were balanced against MRM, considering pathologic analysis as the gold standard. For fatty breasts (n=47), exact measurement was found on mammography plus US and on MRM alone in 70%, underestimation on mammography plus US 23.5% and on MRM 11% (P=0.005). For dense breasts (n=50), exact measurement was found on mammography plus US in 40% and on MRM alone 68%, underestimation on mammography plus US 52% and on MRM 10% (P=0.005). Overall, good correlation (R>0.71) was found between pathologic and clinical size with all imaging methods; nevertheless, when evaluating multifocal/multicentric disease, a poor correlation was observed between histologic assessment and mammography plus US (R=0.52), but it was excellent with regard to MRM (R=0.99). In fatty breasts, the combination of mammography and US allows for a precise assessment of tumoral extension. However, these results show that in dense breasts, MRM is superior to mammography plus US, suggesting that its systematic use in this group of patients is justifiable.
