Effects of combined exercises on shoulder mobility and strength of the upper extremities in breast cancer rehabilitation: a 3-week randomized controlled trial

PURPOSE

The aim of this study was to analyze the effects of mobility training with FIVE® devices in combination with device-supported strength exercises for shoulder mobility and strength of the upper extremities in women with breast cancer.

METHODS

We conducted a pretest-posttest intervention study with female breast cancer patients (n = 41) who were randomly assigned to two groups by lot during their stationary follow-up treatment at a rehabilitation clinic in the south of Germany between February and March 2020. As part of exercise therapy, the intervention group (n = 24) performed a mobility training with FIVE® devices combined with device-supported strength training, whereas the control group (n = 17) completed device-supported strength training. Before and after the 3-week intervention (3 training sessions/week), shoulder mobility and isokinetic maximal strength were tested.

RESULTS

Both groups achieved significant improvements in shoulder mobility in the frontal and sagittal plane (between 3.8 and 15.35%; p < 0.05) and in strength performance (31.36% [IG] vs. 51.24% [CG]; p < 0.001). However, no robust evidence could be determined about potential interaction effects.

CONCLUSION

A combined device-supported strength and mobility training (FIVE®) showed no advantages. Therefore, a variety of exercise methods is possible in exercise therapy of breast cancer patients.

CLINICAL TRIAL REGISTRATION NUMBER

Since the University of Education Weingarten does not assign clinical trial registration numbers or ethical approval numbers, none could be assigned for this study.

Racial disparity in breast cancer survivorship: themes from a series of four national healthcare provider live virtual forums

PURPOSE

Significant disparity exists in the diagnosis, treatment, and survivorship outcomes among Black breast cancer (BC) survivors. Black BC survivors have more significant survivorship issues and a greater burden of illness than White counterparts. Barriers to rehabilitation exist for all BC survivors but are magnified in Black BC survivors. The purpose of this qualitative research was to document patient, clinician, and researchers' perceptions surrounding contributing factors, lived experiences, and potential solutions to racial disparity in BC survivorship.

METHODS

A narrative approach was utilized to identify themes from a series of four virtual healthcare provider forums that explored lived personal and professional experiences, issues, and potential solutions surrounding racial disparity in BC survivorship. Forums included perspectives of patients, healthcare providers, researchers, and stakeholders in the BC field. An independent thematic analysis was performed by the investigators, all of whom have emic perspectives with respect to race and/or BC.

RESULTS

Three main themes were identified related to racial disparity in BC survivorship: (1) societal and cultural contributing factors, (2) contribution of healthcare providers and systems, and (3) models of care and research considerations.

CONCLUSIONS

The findings provide compelling documentation of lived personal and professional experiences of racial disparity in BC survivorship. Potential solutions exist and must be enacted immediately to ensure equitable survivorship outcomes for Black individuals following a BC diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

Increased awareness related to racial disparity in BC survivorship among survivors, healthcare providers, and researchers will contribute to health equity and improved outcomes for Black individuals.

Risk factors for reduced function in women with a history of breast cancer

PURPOSE

People with a history of breast cancer are at risk of losing function during and after treatment. Unfortunately, little is known about the individual and additive effects of specific treatment, disease-related, and demographic factors that may contribute to functional decline. This manuscript reports the results of a multi-center study to evaluate the effects of these factors on function.

METHODS

In this cross-sectional study, women with a history of breast cancer referred to physical medicine and rehabilitation cancer rehabilitation clinics were administered the PROMIS® Cancer Function Brief 3D Profile to evaluate function in the domains of physical function, fatigue, and social participation. Clinical and demographic information, including treatment history and disease status, was recorded by clinicians. Patients were analyzed in two groups: those with active disease on antineoplastic treatment, and those with no evidence of disease (NED). A multivariable model was constructed to detect associations between clinical and demographic factors.

RESULTS

In patients with NED, the presence of chemotherapy-induced peripheral neuropathy (CIPN) was strongly associated with reduced function in all three domains. In those with active disease, having brain metastases was significantly associated with reduced function in all domains and CIPN with reduced physical function. Radiation was associated with improved function in both cohorts.

CONCLUSIONS

Among women seeking rehabilitative care, CIPN and the presence of brain metastases were most strongly associated with a decline in function. The effects of radiation on function were unexpected and may be partially explained by the treatment's role in symptom management. Clinicians who treat breast cancer should consider a patient's functional status when providing supportive care.

An infrared 3D scanning device as a novel limb volume measurement tool in breast cancer patients

Abstract

Background

Lymphedema is a common complication of breast cancer treatment that affects one in five breast cancer survivors, yet there is no reliable method to detect lymphedema in the subclinical range. The objective of this study was to determine the feasibility and reliability of using an infrared 3D scanning device (ISD) as a peri-operative limb volume measurement tool.

Methods

Fifteen patients were analyzed based on inclusion criteria. Peri-operative measurements were obtained using tape measure and an ISD. Volumes were calculated using a standard algorithm for tape measure and a custom algorithm for ISD measurements. Linear regression models were used to assess ISD and tape measurement volume and circumference correlation. One-way ANOVA was used to compare change in percent difference at set time points post-operatively (2–3 weeks, 4–6 weeks, and 7–12 weeks) for both ISD and tape measure. t tests for unequal variances with the Bonferroni correction were performed among these groups.

Results

There is a positive linear correlation (R² = 0.8518) between absolute volume measurements by the ISD and tape measure. Analyses over 2–10 weeks post-operatively showed that the ISD was able to detect volume changes in both the unaffected and the affected arm. Furthermore, the affected arm tended to have a greater increase in volume in the majority of patients, indicating these patients could be at risk for lymphedema.

Conclusions

Technology utilizing infrared 3D scanners can reliably measure limb volume pre- and post-treatment similarly to tape measure in a small sample of patients. Further research using 3D scanning technology with a longer follow up is warranted.

Exercise intensity and cardiovascular health outcomes after 12 months of football fitness training in women treated for stage I-III breast cancer: Results from the football fitness After Breast Cancer (ABC) randomized controlled trial

PURPOSE

To examine the exercise intensity and impact of 12 months of twice-weekly recreational football training on cardiorespiratory fitness (CRF), blood pressure (BP), resting heart rate (HR_rest), body fat mass, blood lipids, inflammation, and health-related quality of life in women treated for early-stage breast cancer (BC).

METHODS

Sixty-eight women who had received surgery for stage I-III BC and completed adjuvant chemo- and/or radiation therapy within 5 years were randomized in a 2:1 ratio to a Football Fitness group (FFG, n = 46) or a control group (CON, n = 22). Football Fitness sessions comprised a warm-up, drills and 3-4 × 7 min of small-sided games (SSG). Assessments were performed at baseline, 6 months and 12 months. Outcomes were peak oxygen uptake (VO₂peak), blood pressure (BP), HR_rest, total body fat mass, and circulating plasma lipids and hs-CRP, and the 36-Item Short Form Health Survey (SF36). Intention-to-treat (ITT) analyses were performed using linear mixed models. Data are means with SD or 95% confidence intervals.

RESULTS

Adherence to training in participants completing the 12-months follow-up (n = 33) was 47.1% (22.7), and HR during SSG was ≥80% of HR_max for 69.8% (26.5) of total playing time. At baseline, VO₂peak was 28.5 (6.4) and 25.6 (5.9) ml O₂/kg/min in FFG and CON, respectively, and no significant changes were observed at 6- or 12 months follow-up. Systolic BP (SBP) was 117.1 (16.4) and 116.9 (14.8) mmHg, and diastolic BP (DBP) was 72.0 (11.2) and 72.4 (8.5) mmHg in FFG and CON, respectively, at baseline, and a 9.4 mmHg decrease in SBP in CON at 12 months resulted in a between-group difference at 12 months of 8.7 mmHg (p = .012). Blood lipids and hs-CRP were within the normal range at baseline, and there were no differences in changes between groups over the 12 months. Similarly, no differences between groups were observed in HR_rest and body fat mass at 6- and12-months follow-up. A between-group difference in mean changes of 23.5 (0.95-46.11) points in the role-physical domain of the SF36 survey favored FFG at 6 months.

CONCLUSION

Football Fitness training is an intense exercise form for women treated for breast cancer, and self-perceived health-related limitations on daily activities were improved after 6 months. However, 1 year of Football Fitness training comprising 1 weekly training session on average did not improve CRF, BP, blood lipids, fat mass, or HR_rest.
