Age-Related Differences in Exercise and Quality of Life among Breast Cancer Survivors

Sexuality, fertility, family planning, family life, and partnership in young breast cancer patients: a longitudinal study

Objectives

Adolescent and young adult (AYA) breast cancer patients are often faced with sexuality-related problems. Since healthcare providers are often unfamiliar with problems specific to AYA cancer this topic is too little integrated into routine oncological care. The objective of this study was to analyze sexuality, fertility, family planning, family life, and partnership regarding satisfaction and supportive care needs in AYA breast cancer patients.

Methods

A total of 139 AYA breast cancer patients were examined twice, 1 year apart. The patients were asked to complete several questionnaires and to answer multiple questions about satisfaction with sexuality, fertility, family planning, family life, and corresponding supportive care needs in these domains.

Results

While the patients were largely satisfied with their family life and partnerships, they were less satisfied with their sexuality and family planning. Only small mean score changes were observed in these variables over the course of a year. Being a parent already and having the possibility of further completing family planning were strongly associated with higher satisfaction and lower supportive care needs in these domains. Satisfaction was generally negatively associated with supportive care needs. Older age was predictive of lower satisfaction with sexuality at follow-up.

Conclusion

AYA cancer patients deserve special consultations concerning the impact of cancer and treatment on their sexuality and fertility, and it is especially important that women who have yet to complete their family planning be actively offered information and support concerning sexuality and fertility protection before beginning treatment.

The Analgesic Effect of Resistance Training after Breast Cancer (ANTRAC): A Randomized Controlled Trial

OBJECTIVE

The objective of this blinded parallel-arm randomized controlled trial was to investigate the effect of resistance training (RT) on pain, maximal strength, and shoulder function in breast cancer survivors (BCS) with persistent pain after treatment.

METHODS

Twenty BCS with self-reported pain ≥1.5 yr after treatment were randomized to an experimental group (EXP, n = 10), who performed a supervised progressive total body heavy RT program 2 times per week for 12 wk, or a control group (CON, n = 10), who was instructed to continue their everyday life. Perceived pain intensity, pressure pain threshold (PPT) levels, one-repetition maximum (1RM), and active range of motion were collected pre- and postintervention and at 3 months follow-up.

RESULTS

There was a significant 11% decrease in peak pain intensity ( P < 0.05) for both groups, a significant 48% increase in 1RM ( P < 0.05), and a significant 35% increase in PPT levels ( P < 0.001) for EXP, but not for CON. For EXP, maximal strength at follow-up was still significantly greater than at preintervention ( P < 0.05), whereas PPT levels had reverted to baseline levels. There was no change in active range of motion ( P < 0.05) and no change in arm circumference ( P < 0.05).

CONCLUSIONS

RT had a significant effect on 1RM and PPT of BCS with persistent pain after treatment, demonstrating both a functional and analgesic effect of progressive RT in this population. Strength was largely maintained after detraining, whereas PPT levels were not, indicating that the process of RT rather than the gain in strength may be associated with analgesia.

Pain sensitivity and shoulder function among breast cancer survivors compared to matched controls: a case-control study

OBJECTIVE

Persistent pain and loss of shoulder function are common adverse effects to breast cancer treatment, but the extent of these issues in comparison with healthy controls is unclear for survivors beyond 1.5 years after treatment. The purpose of this study was to benchmark differences in pressure pain thresholds (PPT), maximal isokinetic muscle strength (MIMS), and active range of motion (ROM) of females with persistent pain ≥1.5 years after breast cancer treatment (BCS) compared with pain-free matched controls (CON), and examine the presence of movement-evoked pain (MEP) during assessment of MIMS.

METHODS

The PPTs of 18 locations were assessed using a pressure algometer and a numeric rating scale was used to assess intensity of MEP. Active ROM and MIMS were measured using a universal goniometer and an isokinetic dynamometer, respectively.

RESULTS

A two-way analysis of variance revealed that PPTs across all locations, MIMS for horizontal shoulder extension/flexion and shoulder adduction, active ROM for shoulder flexion, horizontal shoulder extension, shoulder abduction, and external shoulder rotation were significantly lower for BCS compared with CON (P < 0.05). MEP was significantly higher for BCS and MEP intensity had a significant, negative correlation with PPTs (P < 0.01).

DISCUSSION/CONCLUSION

BCS with persistent pain ≥1.5 years after treatment demonstrates widespread reductions in PPTs and movement-specific reductions in MIMS and active ROM of the affected shoulder, along with MEP during physical performance assessment.

IMPLICATIONS FOR CANCER SURVIVORS

BCS with persistent pain ≥1.5 years after treatment shows signs of central sensitization and may benefit from individualized rehabilitation.

Factors Influencing Exercise Following Pancreatic Tumor Resection

BACKGROUND

We previously demonstrated associations between exercise during pancreatic cancer treatment and quality of life and physical fitness prior to pancreatectomy. In this study, we quantified exercise among survivors following pancreatic tumor resection and characterized concordance with established guidelines.

METHODS

We quantified exercise frequency, duration, and intensity among survivors who underwent pancreatectomy for adenocarcinoma or a neuroendocrine tumor at our center from 2000 to 2017 and compared them with American College of Sports Medicine Guidelines for Cancer Survivors. Additional surveys measured motivation to exercise, barrier self-efficacy, quality of life, and fatigue. Multivariable models were constructed to evaluate associations between clinicodemographic and psychosocial variables and guideline concordance, and between guideline concordance and quality of life and fatigue.

RESULTS

Of 504 eligible survivors, 262 (52%) returned surveys. Only 62 participants (24%) reported meeting both aerobic and strengthening guidelines; 103 (39%) reported meeting neither. Adjusted analyses demonstrated that higher autonomous motivation was associated with higher aerobic and strengthening guideline concordance (both p < 0.01). Higher barrier self-efficacy and older age were associated with higher aerobic guideline concordance (p < 0.01). We identified no significant associations between guideline concordance and tumor type, time since surgery, or recent cancer therapy (all p > 0.05). We found favorable associations between aerobic guideline concordance and both quality of life and fatigue (both p < 0.001).

CONCLUSIONS

Less than one-quarter of participants exercised sufficiently to meet national exercise guidelines following pancreatectomy. To maximize exercise and related benefits, interventions should help survivors increase intrinsic motivation and overcome barriers to exercise.

Municipality-based pragmatic rehabilitation stratified in accordance with individual needs-results from a longitudinal survey study

OBJECTIVE

Evidence on municipality-based cancer rehabilitation is sparse. This longitudinal study explores the following: (1) Rehabilitation needs, (2) effectiveness of municipality-based rehabilitation, and (3) whether rehabilitative services are stratified according to individual needs in breast cancer patients.

METHODS

We collected data from a longitudinal survey among 82 breast cancer patients referred to municipality-based rehabilitation at the Copenhagen Centre for Cancer and Health. Rehabilitation needs, health-related quality of life (HRQoL), and functional status were collected using patient-reported outcomes (PROs) including distress thermometer, problem list, Functional Assessment of Cancer Therapy-Breast questionnaire (FACT-B), and upper body function with the abbreviated disability of the arm, shoulder, and hand (Quick-DASH) questionnaire. Data collection time points are as follows: entry, follow-up, and end of intervention.

RESULTS

At referral, scores were (mean (range)) distress 4.0 (0-10), problems 9.5 (0-24), and FACT-B 103.0 (49.8-135.5). HRQoL increased during rehabilitation (FACT-B ∆ mean 8.1 points (> MID, p < 0.0001)); 56% had a positive change, 34% no difference, and 11% a decline. Those with the lowest FACT-B entry score had significantly longer duration of rehabilitation (10.9 vs 8.7 months, p < 0.001), higher number of services (7.0 vs 5.3, p < 0.003), and participated more in group-based exercise (+3 sessions: 57% vs 8%, p < 0.001).

CONCLUSION

This is the first study to report on pragmatic municipality-based cancer rehabilitation. The results suggest that services are aimed at patients with rehabilitation needs, improve HRQoL, and are properly stratified to those who need it the most. We suggest future monitoring of municipality-based rehabilitation services to ensure quality of care.

Feasibility of smartphone application and social media intervention on breast cancer survivors' health outcomes

Breast cancer survivors are at risk for poor health, with physical activity a possible treatment. Little research has examined how technology might promote breast cancer survivor physical activity or health. The aim of this study is to investigate the feasibility of employing a commercially available mobile health application- and social media-based health education intervention to improve breast cancer survivor physical activity or health.Ten breast cancer survivors (X̅ age = 45.80 ± 10.23 years; X̅ weight = 79.51 ± 20.85 kg) participated in this 10-week single-group pilot study from 2015 to 2016. Participants downloaded the MapMyFitness application, documented all physical activity with MapMyFitness, and were enrolled in a Social Cognitive Theory-based, Facebook-delivered health education intervention. Objectively measured physical activity, weight or body composition, cardiovascular fitness, psychosocial constructs, and quality of life indices were measured at baseline and 10 weeks. Intervention use and acceptability was evaluated during and following the intervention. Descriptive statistics were calculated for all study outcomes, with qualitative analyses performed regarding use and acceptability.At postintervention, average daily moderate-to-vigorous physical activity and steps increased by 2.6 min and 1,657, respectively, with notable decreases in weight (2.4 kg) and body fat percentage (2.3%). Physical activity-related social support and ability to engage in social roles or activity demonstrated the greatest improvements among all psychosocial and quality of life indices, respectively. Participants enjoyed the feedback and tracking features of MapMyFitness, with most finding the Facebook component helpful. All participants recommended the intervention for future use.Physical activity interventions combining commercially available mobile health applications and theoretically based social media-delivered health interventions may promote certain physiological, psychosocial, and quality of life outcomes among breast cancer survivors. Larger samples and randomized studies are warranted.

Effectiveness of Combined Smartwatch and Social Media Intervention on Breast Cancer Survivor Health Outcomes: A 10-Week Pilot Randomized Trial

Physical activity (PA) among breast cancer survivors (BCS) can improve this population's health and quality of life (QoL). This study evaluated the effectiveness of a combined smartwatch- and social media-based health education intervention on BCS's health outcomes. Thirty BCS ( X ¯ age = 52.6 ± 9.3 years; X ¯ Wt = 80.2 ± 19.6 kg) participated in this 10-week, 2-arm randomized trial, with BCS randomized into: (1) experimental group (n = 16): received Polar M400 smartwatches for daily PA tracking and joined a Facebook group wherein Social Cognitive Theory-related PA tips were provided twice weekly; and (2) comparison group (n = 14): only joined separate, but content-identical Facebook group. Outcomes included PA, physiological, psychosocial, and QoL variables. Specifically, PA and energy expenditure (EE) was assessed by ActiGraph GT3X+ accelerometers while physiological, psychosocial, and QoL were examined via validated instruments at baseline and post-intervention. No baseline group differences were observed for any variable. Ten BCS dropped out of the study (experimental: 4; comparison: 6). Compared to completers, dropouts differed significantly on several outcomes. Thus, a per-protocol analysis was performed, revealing significant group differences for changes in social support (t = -2.1, p = 0.05) and barriers (t = -2.2, p = 0.04). Interestingly, the comparison group demonstrated improvements for both variables while the intervention group demonstrated slightly decreased social support and no change in barriers. Notably, both groups demonstrated similarly increased daily light PA, moderate-to-vigorous PA, EE, and steps of 7.7 min, 5.1 min, 25.1 kcals, and 339 steps, respectively, over time. Despite extensive user training, several experimental BCS found the Polar M400 use difficult-possibly decreasing intervention adherence. Future interventions should utilize simpler smartwatches to promote PA among middle-aged clinical/non-clinical populations.

Physical Activity and Sedentary Behavior in Breast and Colon Cancer Survivors Relative to Adults Without Cancer

OBJECTIVE

To assess differences in accelerometer-assessed moderate- to vigorous-intensity physical activity (MVPA), light-intensity physical activity, and sedentary time between cancer survivors and adults without cancer.

PATIENTS AND METHODS

Accelerometer data collected from 241 breast cancer survivors (ACCEL-Breast study, 2013) and 171 colon cancer survivors (ACCEL-Colon study, 2012-2013) were pooled with data collected from adults without cancer (Australian Diabetes, Obesity and Lifestyle accelerometer substudy, 2011-2012). Linear regression was used to estimate differences in physical activity and sedentary behavior levels between cancer survivors and adults without cancer, adjusted for potential confounding factors.

RESULTS

The mean MVPA was significantly higher among breast cancer survivors than among females who had not had cancer (29 vs 22 min/d; P<.001). Colon cancer survivors had significantly lower levels of light activity than did adults without cancer (311 vs 338 min/d; P<.001), more sedentary time (532 vs 507 min/d; P=.003), and more prolonged sedentary time (210 vs 184 min/d; P=.002).

CONCLUSION

Contrary to findings from previous research (based on self-reported physical activity), cancer survivors engaged in more (breast) or equivalent (colon) MVPA compared with adults without cancer. Differences between colon cancer survivors and adults without cancer for light activity and sedentary behavior highlight the importance of considering the full activity spectrum in the context of cancer control.

Get Healthy after Breast Cancer - examining the feasibility, acceptability and outcomes of referring breast cancer survivors to a general population telephone-delivered program targeting physical activity, healthy diet and weight loss

PURPOSE

This pilot study assessed the feasibility, acceptability and outcomes of referring breast cancer survivors to the 'Get Healthy Service' (GHS), a state health-funded 6-month telephone-delivered lifestyle program.

METHODS

Pre-post study with eligible and consenting women following treatment for stages I-III breast cancer referred by nurses in a cancer treatment centre to the GHS. Feasibility was assessed via GHS uptake and completion; acceptability was assessed via patient satisfaction and nurse feedback. Changes in weight, physical activity, diet, quality of life (QoL) and fatigue from baseline to 6 months were examined.

RESULTS

Fifty-three women (mean ± SD body mass index, 31.0 ± 5.5 kg/m²; age, 57.3 ± 10.0 years; 14.0 ± 7.1 months post-diagnosis; 43.4% born outside Australia, 49% high school or less education, 32.1% English as a second language) took up the GHS, with 62% completing the program. Almost all (92%) completers had high satisfaction ratings and breast nurses provided positive feedback. Findings from GHS completers (n = 33) show a statistically significant effect from baseline to 6 months for weight loss (mean ± SE; -2.4 ± 0.7 kg; p = 0.002) and total physical activity minutes per week (55 ± 18 min/week; p = 0.006). No significant changes in fruit or vegetable servings per day or takeaways and fast food frequency per week were observed. A significant improvement in mental QoL was observed (3.5 ± 1.6; p = 0.041), but not for physical QoL or fatigue.

CONCLUSION

GHS referral appeared feasible, acceptable and effective for a diverse group of women following completion of treatment for breast cancer, yet more remains to be done to fully integrate GHS screening and referral into usual care.

The Living Well after Breast Cancer™ Pilot Trial: a weight loss intervention for women following treatment for breast cancer

AIM

Obesity is associated with poor prognosis and risk of treatment side-effects in breast cancer survivors. This pilot study assessed the feasibility, acceptability, safety and efficacy of a telephone-delivered weight loss intervention, among women (BMI 25-40 kg/m² ) following treatment for stage I-III breast cancer, on weight loss (primary outcome), quality of life and treatment-related side-effects (vs usual care).

METHODS

Ninety women (mean ± SD age: 55.3 ± 8.7years; BMI: 31.0 ± 4.3 kg/m² ; 15.9 ± 2.9 months postdiagnosis), recruited from a state-based cancer registry, were randomized to a weight loss (diet and physical activity) intervention (n = 45) or usual care (n = 45). Data collected at baseline and 6 months included weight, body composition, quality of life, fatigue and body image. Acceptability and satisfaction were assessed in intervention participants.

RESULTS

Oncologists provided consent to contact 82.6% of patients, with 84.1% of those women contacted and eligible consenting to participate. Compared with usual care, mean weight loss was significantly greater in the intervention arm (-3.1 kg [95% CI, -5.4 to -0.7]; -3.7% baseline weight [95% CI, -6.6 to -0.9]), as were reductions in fat mass (-2.1 kg [95% CI, -4.2 to -0.1]) and waist circumference (-4.0 cm [95% CI, -6.6 to -1.3]). No other statistically significant intervention effects were observed. Participants were highly satisfied with the intervention overall and it is timing in relation to diagnosis/treatment. One reported adverse event (musculoskeletal injury) was attributable to the intervention.

CONCLUSIONS

This weight loss intervention was feasible, acceptable, safe and effective for women 1-2 years after a breast cancer diagnosis. The effect of weight loss on quality of life and treatment-related side-effects should be examined further in fully-powered studies.

Circadian rhythm mediates the relationship between physical activity and quality of life in younger and older cancer survivors

Increasing evidence suggests that physical activity (PA) improves the quality of life (QoL) of cancer survivors. However, the biological mechanisms underlying the relationship between PA and QoL are unclear. The purpose of this study was to determine whether the relationship between PA and QoL differs in younger and older cancer survivors and whether circadian rhythm (CR) mediates this relationship. We also explored the effect of the CR on QoL. The participants were 235 cancer survivors, comprising 143 younger and 92 older patients. Data were collected using the Taiwanese versions of the Physical Activity Scale for the Elderly and Short Form-36. The robustness and stability of the CR were measured using an actigraph. Mediation was tested using multiple mediation analyses. The CR mediated the relationship between PA and the physical domain of QoL in younger and older cancer survivors (23% and 59% mediating effects, respectively). The CR partially mediated the effect of PA on the mental dimension of QoL in older cancer survivors (36% mediating effect), but not in younger cancer survivors. Cancer survivors with a more robust CR had a significantly higher QoL, particularly in the physical functioning domain (d = 0.43, p < 0.001). The results provided evidence that the CR mediated the relationship between PA and QoL. Moreover, this mediating effect differed in younger and older cancer survivors. These results can serve as a reference for designing individualized PA programs for cancer survivors.

Weight loss intervention trials in women with breast cancer: a systematic review

Obesity has been associated with poor health outcomes in breast cancer survivors. Thus, weight loss is recommended for overweight and obese survivors. We systematically reviewed studies (published up to July 2013) that evaluated behaviourally based, weight loss interventions in women with breast cancer exclusively. Completed randomized trials, single-arm trials and ongoing trials were reviewed. Within-group and between-group differences for weight loss were extracted, as was data on secondary outcomes, i.e. clinical biomarkers, patient-reported outcomes, adverse events. Ten completed randomized trials, four single-arm trials and five ongoing trials were identified. Statistically significant within-group weight loss was observed over periods of 2 to 18 months in 13 of the 14 trials, with six randomized and two single-arm trials observing mean weight loss ≥5%. Clinical biomarkers, psychosocial and patient-reported outcomes were measured in a small number of studies. No serious adverse events were reported. Only two trials assessed maintenance of intervention effects after the end-of-intervention and none reported on cost-effectiveness. The studies included in this review suggest that weight loss is feasible to achieve and is safe in women following treatment for breast cancer. Future studies should assess (and be powered for) a range of biomarker and patient-reported outcomes, and be designed to inform translation into practice.

Meta-analysis of the effects of exercise intervention on quality of life in breast cancer survivors

Breast cancer is the most common type of cancer among women worldwide. Diagnosis and treatment of breast cancer pose an array of physical and psychological threats to the survivors. Exercise interventions may be particularly appropriate for cancer survivors because they have the potential to improve physical and psychological functioning. The review aims to examine the effectiveness of exercise intervention on the quality of life (QOL) of breast cancer survivors. Five databases (Medline, CINAHL, Scopus, The Cochrane Library, and CAJ Full-text Database) were searched from 2003 to July 2013. Clinical controlled trials of exercise interventions for breast cancer survivors who were at least 18 years old and had completed active cancer treatment were included. A total of 25 trials were included in this study, of which 19 were pooled together statistically. Subjects in the exercise interventions had higher overall QOL than subjects in the control group. The standardized mean difference (SMD) for changes in overall general QOL scores was 0.70 (95 % CI 0.21, 1.19). The SMD for changes in cancer-specific QOL scores was 0.38 (95 % CI 0.03, 0.74). For cancer-specific QOL domains, there were positive but non-significant trends in two QOL domains (breast symptoms: Z score = 1.12, p = 0.26; arm symptoms: Z score = 1.32, p = 0.19). This study provides updated findings supporting the idea that exercise interventions have statistically significant effects on overall QOL in breast cancer survivors, as well as positive trends for cancer site-specific QOL domains (breast and arm symptoms).

Exercise behaviors in breast cancer survivors in Taiwan

BACKGROUND

Although exercise is a recommended rehabilitation intervention for many breast cancer survivors, exercise activity after cancer treatment is rarely reported in this patient group in Taiwan.

OBJECTIVE

The objectives of this study were to analyze trends in exercise activity in breast cancer survivors in Taiwan.

INTERVENTIONS/METHODS

This prospective, longitudinal study with repeated-measures design used standardized instruments to measure trends in exercise activity but performed no treatments or interventions.

RESULTS

Of the 196 breast cancer survivors who participated in this study, 39% regularly engaged in light-to-moderate intensity exercise for approximately 15 minutes per day throughout the 6-month period of the study. Of these, 40% indicated that their exercise stage had increased, and only 13% indicated that their exercise stage had decreased. The most common exercise activities were walking, hiking, calisthenics, folk dancing, chi kung and tai chi. Although most women reported that exercise made them feel better both physically and emotionally, most said that they exercised mainly for health maintenance reasons.

CONCLUSIONS

Frequency, duration, and intensity of exercise significantly increased during the 6-month study but did not reach the recommended levels. Most women believed that physical activity enhanced their recovery from cancer treatment.

IMPLICATIONS FOR PRACTICE

When planning patient education interventions for breast cancer survivors, healthcare professionals should consider not only the role of exercise in breast cancer recovery, but also trends in exercise behavior among breast cancer survivors. The findings of this study contribute to the literature on exercise trends in breast cancer survivors.

Telehealth system (e-CUIDATE) to improve quality of life in breast cancer survivors: rationale and study protocol for a randomized clinical trial

Background

Breast cancer survivors suffer physical impairment after oncology treatment. This impairment reduces quality of life (QoL) and increase the prevalence of handicaps associated to unhealthy lifestyle (for example, decreased aerobic capacity and strength, weight gain, and fatigue). Recent work has shown that exercise adapted to individual characteristics of patients is related to improved overall and disease-free survival. Nowadays, technological support using telerehabilitation systems is a promising strategy with great advantage of a quick and efficient contact with the health professional. It is not known the role of telerehabilitation through therapeutic exercise as a support tool to implement an active lifestyle which has been shown as an effective resource to improve fitness and reduce musculoskeletal disorders of these women.

Methods / Design

This study will use a two-arm, assessor blinded, parallel randomized controlled trial design. People will be eligible if: their diagnosis is of stages I, II, or IIIA breast cancer; they are without chronic disease or orthopedic issues that would interfere with ability to participate in a physical activity program; they had access to the Internet and basic knowledge of computer use or living with a relative who has this knowledge; they had completed adjuvant therapy except for hormone therapy and not have a history of cancer recurrence; and they have an interest in improving lifestyle. Participants will be randomized into e-CUIDATE or usual care groups. E-CUIDATE give participants access to a range of contents: planning exercise arranged in series with breathing exercises, mobility, strength, and stretching. All of these exercises will be assigned to women in the telerehabilitation group according to perceived needs. The control group will be asked to maintain their usual routine. Study endpoints will be assessed after 8 weeks (immediate effects) and after 6 months. The primary outcome will be QoL measured by The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0 and breast module called The European Organization for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life questionnaire. The secondary outcomes: pain (algometry, Visual Analogue Scale, Brief Pain Inventory short form); body composition; physical measurement (abdominal test, handgrip strength, back muscle strength, and multiple sit-to-stand test); cardiorespiratory fitness (International Fitness Scale, 6-minute walk test, International Physical Activity Questionnaire-Short Form); fatigue (Piper Fatigue Scale and Borg Fatigue Scale); anxiety and depression (Hospital Anxiety and Depression Scale); cognitive function (Trail Making Test and Auditory Consonant Trigram); accelerometry; lymphedema; and anthropometric perimeters.

Discussion

This study investigates the feasibility and effectiveness of a telerehabilitation system during adjuvant treatment of patients with breast cancer. If this treatment option is effective, telehealth systems could offer a choice of supportive care to cancer patients during the survivorship phase.

Quality of life, fertility concerns, and behavioral health outcomes in younger breast cancer survivors: a systematic review

BACKGROUND

Breast cancer is the most common cancer in women younger than age 50 years. Cancer treatments in younger women may cause premature menopause, infertility, and negative psychosocial effects. In this systematic review, we examined three key domains of functioning that are particularly relevant for younger breast cancer survivors: health-related quality of life (QOL), menopausal symptoms and fertility concerns, and behavioral health outcomes.

METHODS

We conducted a literature review using PubMed and secondary sources and examined 840 articles published between January 1990 and July 2010. Inclusion criteria for articles were 1) published in English after 1989; 2) exclusively analyzed female breast cancer survivors aged 50 years or younger or premenopausal at diagnosis, with baseline characteristics and/or quantitative or descriptive analyses for this age group; 3) investigated QOL (health-related QOL including physical functioning and mental health, depression, and anxiety), menopause- or fertility-related concerns, and weight gain or physical activity-related behavioral health outcomes. Data were extracted using a standardized table collecting the purpose, design, population, and results of each study. Extracted data were reviewed for accuracy by two investigators and presented as descriptive tables.

RESULTS

A total of 28 articles met the inclusion criteria (15 cross-sectional studies, eight longitudinal studies, and five randomized trials). Regarding data review, no discordance between investigators was noted. Standardized measures of QOL and depressive symptoms identified worse outcomes as being more frequent or severe in breast cancer survivors aged 50 years or younger when compared with the general age-matched population of women without cancer and to older women (aged >50 years) with breast cancer. Concerns about premature menopause, menopausal symptoms, and infertility were common in younger women (aged ≤ 50 years) and had a role in the level of distress after treatment. Weight gain and physical inactivity were common health outcomes in younger women.

CONCLUSIONS

Younger women with breast cancer were found to experience distinct psychosocial and menopause-related concerns, weight gain, and physical inactivity. A need for more longitudinal research, including efforts at intervention to manage these symptoms and adverse health outcomes, remains.

Physical activity, quality of life and symptoms of depression in community-dwelling and institutionalized older adults

This study was aimed to investigate in a sample of Spanish elderly whether measures of physical activity are related to health-related quality of life (HRQoL) and symptoms of depression in community dwelling and institutionalized elderly. The sample was a cohort of 436 elderly (234 women and 202 men, aged 60-98 years) from the North of Spain. 58% were community-dwellers and 42% were institutionalized in senior residences. Participants completed measures of physical activity (Yale Physical Activity Survey, YPAS), HRQoL (Medical Outcomes Study 36-item Short Form Health Survey, SF-36) and symptoms of depression (Geriatric Depression Scale, GDS). All SF-36 domains, except role-emotional, were significantly correlated with the YPAS activity dimension summary index. Physical function, role-physical, general health and vitality correlated with total time activity, and correlations were observed between weekly energy expenditure and physical function, role physical, vitality and mental health. Depressive symptom scores correlated significantly with the YPAS activity dimension summary index and the weekly energy expenditure. Scores for various domains of the SF-36 and for depressive symptoms significantly differed among less and more active individuals of the same sex and institutionalization category. Differences generally reached a higher extent in institutionalized subjects in comparison to community dwellers. In conclusion, physical activity was related to different domains of both the physical and mental components of HRQoL and to decreased depressive symptoms. Results emphasize the positive effects of physical activity in both community-dwelling and institutionalized older adults.

Physical activity and breast cancer survivorship

A diagnosis of breast cancer is associated with treatments that have physiologic effects beyond the intended curative therapy. The first section of this chapter provides and integrative physiology review of the effects of breast cancer treatment on the body systems used by and affected by physical activity, including effects of chemotherapy, radiation, and surgery. In later sections, we review the literature on physical activity and breast cancer from the point of diagnosis and for the balance of life. The efficacy of physical activity for supportive cancer care outcomes is reviewed separately from the purported usefulness of physical activity for disease-free and overall survival from breast cancer. The current evidence supports the safety of physical activity during and after breast cancer therapy. The supportive cancer care outcomes for which there is sufficient evidence of efficacy during and after breast cancer treatment include fitness, fatigue, body size, and quality of life. Further, there is growing evidence that upper body exercise does not pose additional risk for negative lymphedema outcomes among survivors with and at risk for lymphedema. For overall survival, the evidence is largely observational, with sufficient evidence that physical activity does confer benefit. Finally, we outline future directions for research on physical activity among breast cancer survivors, including expanding to focus on subsets of the population not included in most prior studies (minority women and older women), tailoring of interventions to stages of cancer most likely to benefit, expanding to study women with metastatic cancer, and new modes of exercise, such as team sports, martial arts, and Pilates.
