Exercise is medicine in oncology: Engaging clinicians to help patients move through cancer.

Multiple organizations around the world have issued evidence-based exercise guidance for patients with cancer and cancer survivors. Recently, the American College of Sports Medicine has updated its exercise guidance for cancer prevention as well as for the prevention and treatment of a variety of cancer health-related outcomes (eg, fatigue, anxiety, depression, function, and quality of life). Despite these guidelines, the majority of people living with and beyond cancer are not regularly physically active. Among the reasons for this is a lack of clarity on the part of those who work in oncology clinical settings of their role in assessing, advising, and referring patients to exercise. The authors propose using the American College of Sports Medicine's Exercise Is Medicine initiative to address this practice gap. The simple proposal is for clinicians to assess, advise, and refer patients to either home-based or community-based exercise or for further evaluation and intervention in outpatient rehabilitation. To do this will require care coordination with appropriate professionals as well as change in the behaviors of clinicians, patients, and those who deliver the rehabilitation and exercise programming. Behavior change is one of many challenges to enacting the proposed practice changes. Other implementation challenges include capacity for triage and referral, the need for a program registry, costs and compensation, and workforce development. In conclusion, there is a call to action for key stakeholders to create the infrastructure and cultural adaptations needed so that all people living with and beyond cancer can be as active as is possible for them.

Weight management and physical activity throughout the cancer care continuum.

Mounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

Electrocardiographic abnormalities and mortality in aging survivors of childhood cancer: A report from the St Jude Lifetime Cohort Study.

BACKGROUND: Electrocardiography (ECG), predictive of adverse outcomes in the general population, has not been studied in cancer survivors. We evaluated the prevalence of ECG abnormalities and associations with mortality among childhood cancer survivors. METHODS: Major and minor abnormalities were coded per the Minnesota Classification system for participants in the St Jude Lifetime Cohort Study (n = 2,715) and community controls (n = 268). Odds ratios (ORs) and 95% CIs were calculated using multivariable logistic regression; and hazard ratios, using Cox proportional hazards regression. RESULTS: Survivors were a median age of 31.3 (range 18.4-63.8) years at evaluation and 7.4 (range 0-24.8) years at diagnosis. Prior therapies included cardiac-directed radiation (29.5%), anthracycline (57.9%), and alkylating (60%) chemotherapies. The prevalence of minor ECG abnormalities was similar among survivors and controls (65.2% vs 67.5%, P = .6). Major ECG abnormalities were identified in 10.7% of survivors and 4.9% of controls (P < .001). Among survivors, the most common major abnormalities were isolated ST/T wave abnormalities (7.2%), evidence of myocardial infarction (3.7%), and left ventricular hypertrophy with strain pattern (2.8%). Anthracyclines ≥300 mg/m2 (OR 1.7 95% CI 1.1-2.5) and cardiac radiation (OR 2.1 95% CI 1.5-2.9 [1-1,999 cGy], 2.6 95% CI 1.6-3.9 [2,000-2,999 cGy], 10.5 95% CI 6.5-16.9 [≥3,000 cGy]) were associated with major abnormalities. Thirteen participants had a cardiac-related death. Major abnormalities were predictive of all-cause mortality (hazard ratio 4.0 95% CI 2.1-7.8). CONCLUSIONS: Major ECG abnormalities are common among childhood cancer survivors, associated with increasing doses of anthracyclines and cardiac radiation, and predictive of both cardiac and all-cause mortality.

Toward a National Initiative in Cancer Rehabilitation: Recommendations From a Subject Matter Expert Group.

The health care delivery system in the United States is challenged to meet the needs of a growing population of cancer survivors. A pressing need is to optimize overall function and reduce disability in these individuals. Functional impairments and disability affect most patients during and after disease treatment. Rehabilitation health care providers can diagnose and treat patients' physical, psychological, and cognitive impairments in an effort to maintain or restore function, reduce symptom burden, maximize independence and improve quality of life in this medically complex population. However, few care delivery models integrate comprehensive cancer rehabilitation services into the oncology care continuum. The Rehabilitation Medicine Department of the Clinical Center at the National Institutes of Health with support from the National Cancer Institute and the National Center for Medical Rehabilitation Research convened a subject matter expert group to review current literature and practice patterns, identify opportunities and gaps regarding cancer rehabilitation and its support of oncology care, and make recommendations for future efforts that promote quality cancer rehabilitation care. The recommendations suggest stronger efforts toward integrating cancer rehabilitation care models into oncology care from the point of diagnosis, incorporating evidence-based rehabilitation clinical assessment tools, and including rehabilitation professionals in shared decision-making in order to provide comprehensive cancer care and maximize the functional capabilities of cancer survivors. These recommendations aim to enable future collaborations among a variety of stakeholders to improve the delivery of high-quality cancer care.

The role of exercise in aromatase inhibitor-induced arthralgia.

Aromatase inhibitors are prescribed in breast cancer due to their associated lower rate of cancer recurrence compared to tamoxifen. However, aromatase inhibitor-induced arthralgia (AIIA) is one of the leading causes of treatment nonadherence, increasing the risk of cancer recurrence. The pathophysiology of AIIA is poorly understood, and although current recommendations for AIIA include lifestyle changes and analgesics depending on the severity of symptoms, there is no established effective treatment. The aim of this study is to explore the presentation and mechanism of AIIA and investigate the feasibility and efficacy of different exercise interventions (aerobic, resistance, aerobic and resistance combined, and yoga or tai chi) in patients with AIIA to guide the development of formal exercise prescription guidelines. Findings indicate that a mixed-modality regimen of aerobic and resistance exercises is feasible and safe and may serve the most benefit in improving joint pain, functionality, and quality of life. More specifically, the weekly regimen should consist of 150 min of aerobic exercise with two sessions of at least six resistance exercises, 8 to 12 repetitions, three sets each. Supplementary yoga and tai chi may be recommended twice a week depending on a patient's target symptoms. Yoga was associated with improved physical functionality, whereas tai chi was related to improvements in mental health. However, the feasibility and impact of combined aerobic and resistance exercise protocols with yoga or tai chi in our target population were not investigated in this review. The use of large, randomized controlled trials is recommended for future studies.

Adherence of stem cell transplant recipients receiving glucocorticoid therapy to an exercise-based rehabilitation program.

The high acuity of hematopoietic stem cell transplant (HSCT) recipients receiving glucocorticoid (GC) therapy for acute graft vs. host disease (aGVHD) may limit their adherence to an exercise-based rehabilitation program and hence, slow their recovery. To make this determination, the medical records of 59 subacute outpatient stem cell transplant recipients receiving methylprednisolone (MP) were reviewed for demographic, anthropometric and medical information. Performance on the repeated sit-to-stand, 50-ft walk and 6-min walk tests were determined before and after completing a 4-week progressive exercise rehabilitation program and outcomes were compared by a paired t-test (P < 0.05). Thirty-two patients (54%) finished a treatment plan (adherent group), completing 80% of the prescribed sessions and were reevaluated. Twenty-seven patients (46%) did not complete the rehabilitation program (nonadherent group), primarily because of readmission to the hospital (18 patients, 62%). The adherent group did not significantly improve their physical performance (p > 0.05). However, a subgroup of 40% of these patients did experience clinically significant improvements in their physical performance.These findings 1) support the feasibility of having HSCT recipients receiving GC therapy to participate in an exercise-based rehabilitation program and 2) suggest that to do so can result in clinically significant improvements in functional capacity.

Parathyroidectomy improves functional capacity in "asymptomatic" older patients with primary hyperparathyroidism: a randomized control trial.

OBJECTIVE: We tested the hypothesis that parathyroidectomy would improve functional/physical capacity, an underlying determinant of the ability to perform activities of daily living (ADL), in older patients with asymptomatic primary hyperparathyroidism (PHPT). SUMMARY OF BACKGROUND DATA: PHPT patients often present with nonspecific, subjective symptoms including proximal muscle weakness, fatigue, and reduced physical functional. Although qualitative data suggest that parathyroidectomy reduces these symptoms in asymptomatic PHPT patients, there are no quantitative data confirming this potential surgical benefit. METHODS: Eighteen asymptomatic older (>50 years) patients with biochemically confirmed PHPT who did not meet National Institutes of Health consensus conference criteria for undergoing a parathyroidectomy were randomly assigned to either a surgical group (parathyroidectomy) or a control group (observed for 6 months). All patients underwent functional testing (6-minute walk test, 50-foot walk test, and repeated sit-to-stand test) at baseline/presurgery and at 6 weeks and 6 months after surgery or baseline. This study is registered at clinicaltrials.gov (Registration# 2007-0220 ID#NCT00501215). RESULTS: The surgery and control groups were functionally similar at baseline. Six-minute walk distance increased in the surgery group by 184 ft, a distance that is both significant (P<0.05) and clinically meaningful. Fifty foot walk and repeated sit-to-stand times in this group remain unchanged from presurgical levels. All functional measures for the control group remained unchanged over time. As anticipated, parathyroidectomy reduced serum calcium and intact parathyroid hormone levels. CONCLUSIONS: The improvement in 6-minute walk distance observed in the surgery group suggests that parathyroidectomy can improve functional capacity, and hence the performance of ADLs in asymptomatic, older PHPT patients.

Synergy Between Licensed Rehabilitation Professionals and Clinical Exercise Physiologists: Optimizing Patient Care for Cancer Rehabilitation.

OBJECTIVES: To differentiate between rehabilitation and exercise training and propose how rehabilitation professionals and exercise physiologists can collaborate to optimize cancer survivor care. DATA SOURCE: Professional organizations and peer-reviewed manuscripts. CONCLUSION: Both professions offer complementary skillsets that, when integrated, optimize the ability of the cancer care team to implement more effective survivorship care plans. Future models of care must incorporate efficient communications between the cancer rehabilitation program and oncology team, include various reimbursement/payment/funding options, and continuously assess program efficacy. IMPLICATIONS FOR NURSING PRACTICE: Nurses must be cognizant of physical needs (ie, functional and conditioning status) and cancer-related comorbidities when referring cancer survivors for exercise reconditioning.

A randomized control trial of a supervised versus a self-directed exercise program for allogeneic stem cell transplant patients.

OBJECTIVES: To determine if therapist supervision of an exercise program produced better functional outcomes in allogeneic stem cell transplant patients than a patient-directed exercise program. METHODS: Sixty-one patients who were less than 6 months post allogeneic stem cell transplant were randomly assigned to either a therapist supervised training group (supervised) or a patient-directed training group (Self-directed). Training consisted of aerobic exercises (treadmill, bicycle ergometer versus walking) and resistance exercises (free weights, weight machines versus resistive band activities). Subjects completed physical performance tests (50-foot fast walk, 6-min walk, forward reach, repeated sit-to-stand, uniped stance) and the Brief Fatigue Inventory (BFI) before and after 4 weeks of training. Pre- and post-training outcomes and group differences were analyzed by a Student t-test. RESULTS: Patients in both groups were similarly deconditioned at baseline. Training increased the 6-min walk distance and 50-foot walk in the supervised group by 12 and 14%, respectively, and increased the 6-min walk distance by 10% in the Self-directed group (p<0.05). BFI score for worst level of fatigue declined in both groups but not significantly. CONCLUSIONS: These results demonstrate that allogeneic transplant patients derive functional benefits from short-term exercise training regardless of how the training program is supervised. Determining (1) the reasons for the low participation rate (28%), (2) the patient-preferred characteristics of each exercise supervision style and (3) how best to match patient preference to exercise supervision style remain significant issues in this area of patient delivery services.

Pulmonary rehabilitation improves functional status in oncology patients.

OBJECTIVE: To determine if participation in a pulmonary rehabilitation (PR) program improved the functional and physiologic status of oncology patients with chronic symptoms of shortness of breath, fatigue, and/or exercise intolerance. DESIGN: Retrospective chart review. SETTING: Comprehensive cancer center. PATIENTS: Oncology patients (N=30) (either a solid or a hematologic malignancy) with chronic dyspnea, exercise intolerance, and/or decreased functional status who had participated in an outpatient PR program. INTERVENTIONS: The PR program used an individualized, progressive aerobic exercise program (2-3 sessions/wk for 8-12 weeks) that consisted of treadmill walking, riding on a bicycle ergometer and exercising on a sliding board. This program also included a didactic educational and psychosocial component. MAIN OUTCOME MEASURES: Functional status and exercise tolerance was assessed by the 6-minute walk test (6MWT) conducted at the beginning and end of the program. Self reports of perceived exertion and dyspnea were collected during and after these tests. Physiologic status was assessed by calculating 6-minute walk work (body mass x 6-minute walk distance). RESULTS: Participation in the outpatient PR program significantly increased the 6-minute walk distance (21%, P<.05) and 6-minute walk work (17%, P<.05). Dyspnea and perceived exertion scores were similar at the pre- and postrehabilitation 6MWT despite the greater physiologic demand of the post-rehabilitation 6-minute walk. No adverse events occurred during the study. CONCLUSIONS: The current study, although limited in size, suggests that participation in a comprehensive outpatient PR program is safe and of benefit in a heterogeneous population of oncology patients with pulmonary symptoms.

Exercise Guidelines for Cancer Survivors: Consensus Statement from International Multidisciplinary Roundtable.

PURPOSE: The number of cancer survivors worldwide is growing, with over 15.5 million cancer survivors in the United States alone-a figure expected to double in the coming decades. Cancer survivors face unique health challenges as a result of their cancer diagnosis and the impact of treatments on their physical and mental well-being. For example, cancer survivors often experience declines in physical functioning and quality of life while facing an increased risk of cancer recurrence and all-cause mortality compared with persons without cancer. The 2010 American College of Sports Medicine Roundtable was among the first reports to conclude that cancer survivors could safely engage in enough exercise training to improve physical fitness and restore physical functioning, enhance quality of life, and mitigate cancer-related fatigue. METHODS: A second Roundtable was convened in 2018 to advance exercise recommendations beyond public health guidelines and toward prescriptive programs specific to cancer type, treatments, and/or outcomes. RESULTS: Overall findings retained the conclusions that exercise training and testing were generally safe for cancer survivors and that every survivor should "avoid inactivity." Enough evidence was available to conclude that specific doses of aerobic, combined aerobic plus resistance training, and/or resistance training could improve common cancer-related health outcomes, including anxiety, depressive symptoms, fatigue, physical functioning, and health-related quality of life. Implications for other outcomes, such as peripheral neuropathy and cognitive functioning, remain uncertain. CONCLUSIONS: The proposed recommendations should serve as a guide for the fitness and health care professional working with cancer survivors. More research is needed to fill remaining gaps in knowledge to better serve cancer survivors, as well as fitness and health care professionals, to improve clinical practice.

American College of Sports Medicine Roundtable Report on Physical Activity, Sedentary Behavior, and Cancer Prevention and Control.

INTRODUCTION: The American College of Sports Medicine convened an International Multidisciplinary Roundtable on Exercise and Cancer in March 2018 to evaluate and translate the evidence linking physical activity and cancer prevention, treatment, and control. This article discusses findings from the Roundtable in relation to the biologic and epidemiologic evidence for the role of physical activity in cancer prevention and survival. RESULTS: The evidence supports that there are a number of biologically plausible mechanisms, whereby physical activity can influence cancer risk, and that physical activity is beneficial for the prevention of several types of cancer including breast, colon, endometrial, kidney, bladder, esophageal, and stomach. Minimizing time spent in sedentary behavior may also lower risk of endometrial, colon and lung cancers. Conversely, physical activity is associated with higher risk of melanoma, a serious form of skin cancer. Further, physical activity before and after a cancer diagnosis is also likely to be relevant for improved survival for those diagnosed with breast and colon cancer; with data suggesting that postdiagnosis physical activity provides greater mortality benefits than prediagnosis physical activity. CONCLUSIONS: Collectively, there is consistent, compelling evidence that physical activity plays a role in preventing many types of cancer and for improving longevity among cancer survivors, although the evidence related to higher risk of melanoma demonstrates the importance of sun safe practices while being physically active. Together, these findings underscore the importance of physical activity in cancer prevention and control. Fitness and public health professionals and health care providers worldwide are encouraged to spread the message to the general population and cancer survivors to be physically active as their age, abilities, and cancer status will allow.

Negative pressure wound therapy achieved by vacuum-assisted closure: Evaluating the assumptions.

Wounds and the accompanying loss of skin integrity often place a patient at increased risk for disability or death. Billions of dollars are spent each year to treat wounds and the effectiveness of these different treatments is highly variable. Following a 1997 publication describing a new treatment therapy that involved creating negative pressure over the wound, many publications have described the purported mechanism of action by which negative pressure may help wounds heal. Although this therapy appears effective, it remains unknown whether it is more effective than other wound closure techniques. In addition, although many uncontrolled, non-randomized studies describing the effectiveness of this therapy have been published, few prospective randomized trials have been conducted. Small sample sizes, variable outcome measures across studies, and significant methodological problems in the available randomized control trials further limit the conclusions that can be drawn regarding the relative effectiveness of vacuum-assisted wound closure. Analysis of these data provides weak evidence to suggest that negative pressure therapy is superior to saline gauze dressings in healing chronic wounds. Randomized controlled trials comparing healing, costs of care, patient pain, and quality-of-life outcomes of this treatment to non-gauze type dressings and other treatment modalities are needed.

A Focused Review of Safety Considerations in Cancer Rehabilitation.

Cancer and its treatments introduce various adverse effects that may affect survivors' physical, cognitive and psychological functioning. Frequently both tolerance to activity and exercise are affected as well. Rehabilitation providers should have substantive knowledge about the effect of cancer progression and common side effects associated with antineoplastic treatment to safely integrate rehabilitation interventions. Rehabilitation may mitigate loss of function and disability; however, these patients are among the most medically complex that providers treat. This report provides a focused review that synthesizes the current evidence regarding disease progression and oncology-directed treatment side effects within the context of safety considerations for rehabilitation interventions throughout the continuum of cancer care. Descriptive information regarding the evidence for precautions and contraindications is provided so that rehabilitation providers can promote a safe plan of rehabilitation care. It is incumbent upon but also challenging for rehabilitation providers to stay up to date on the many advances in cancer treatment, and there are many gaps in the literature regarding safety issues. Although further research is needed to inform care, this review provides clinicians with a framework to assess patients with the goal of safely initiating rehabilitation interventions.

Randomized, controlled trial of yoga in women with breast cancer undergoing radiotherapy.

PURPOSE: Previous research incorporating yoga (YG) into radiotherapy (XRT) for women with breast cancer finds improved quality of life (QOL). However, shortcomings in this research limit the findings. PATIENTS AND METHODS: Patients with stages 0 to III breast cancer were recruited before starting XRT and were randomly assigned to YG (n = 53) or stretching (ST; n = 56) three times a week for 6 weeks during XRT or waitlist (WL; n = 54) control. Self-report measures of QOL (Medical Outcomes Study 36-item short-form survey; primary outcomes), fatigue, depression, and sleep quality, and five saliva samples per day for 3 consecutive days were collected at baseline, end of treatment, and 1, 3, and 6 months later. RESULTS: The YG group had significantly greater increases in physical component scale scores compared with the WL group at 1 and 3 months after XRT (P = .01 and P = .01). At 1, 3, and 6 months, the YG group had greater increases in physical functioning compared with both ST and WL groups (P < .05), with ST and WL differences at only 3 months (P < .02). The group differences were similar for general health reports. By the end of XRT, the YG and ST groups also had a reduction in fatigue (P < .05). There were no group differences for mental health and sleep quality. Cortisol slope was steepest for the YG group compared with the ST and WL groups at the end (P = .023 and P = .008) and 1 month after XRT (P = .05 and P = .04). CONCLUSION: YG improved QOL and physiological changes associated with XRT beyond the benefits of simple ST exercises, and these benefits appear to have long-term durability.

Assessment of voluntary exercise behavior and active video gaming among adolescent and young adult patients during hematopoietic stem cell transplantation.

This pilot study sought to examine the exercise behavior and preferences among adolescent and young adult (AYA) hematopoietic stem cell transplant (HSCT) recipients. Eighteen patients aged 19 to 25 years were recruited to engage in unsupervised exercise activities lasting at least 60 minutes/week during hospitalization for HSCT. Enrolled patients had access to standard exercise activities (walking, resistance training, and basketball) and active video gaming equipment. Physical function (6-Minute Walk Test and Timed-Up-and-Go test) and quality of life (Behavioral, Affective, and Somatic Experiences Scale) were assessed at different time points during admission. Participants exercised an average of 76% of the days during admission and spent an average of 36.5 minutes per day exercising. The Nintendo Wii was the preferred active video gaming equipment, but standard exercises accounted for 73% of all exercise time. Neither functional capacity nor quality of life improved. Results suggest that AYAs voluntarily exercise during HSCT admission, prefer to use standard exercise activities, and may require supervision in order to derive maximum benefits from their efforts. These results provide guidance for developing rehabilitation interventions for AYA HSCT recipients.

The influence of pain distribution on walking velocity and horizontal ground reaction forces in patients with low back pain.

Objective. The primary purpose of this paper was to evaluate the influence of pain distribution on gait characteristics in subjects with low back problems (LBP) during walking at preferred and fastest speeds. Design. Cross-sectional, observational study. Setting. Gait analysis laboratory in a health professions university. Participants. A convenience age- and gender-matched sample of 20 subjects with back pain only (BPO), 20 with referred leg pain due to back problems (LGP), and 20 pain-free individuals (CON). Methods and Measures. Subjects completed standardized self-reports on pain and disability and were videotaped as they walked at their preferred and fastest speeds along a walkway embedded with a force plate. Temporal and spatial gait characteristics were measured at the midsection of the walkway, and peak medial, lateral, anterior, and posterior components of horizontal ground reaction forces (hGRFs) were measured during the stance phase. Results. Patients with leg pain had higher levels of pain intensity and affect compared to those with back pain only (t = 4.91, P < .001 and t = 5.80, P < 0.001, resp.) and walking had an analgesic effect in the BPO group. Gait velocity was highest in the control group followed by the BPO and LGP group and differed between groups at both walking speeds (F(2.57) = 13.62, P < .001 and F(2.57) = 9.09, P < .001, for preferred and fastest speed condition, resp.). When normalized against gait velocity, the LGP group generated significantly less lateral force at the fastest walking speed (P = .005) and significantly less posterior force at both walking speeds (P ≤ .01) compared to the control group. Conclusions. Pain intensity and distribution differentially influence gait velocity and hGRFs during gait. Those with referred leg pain tend to utilize significantly altered gait strategies that are more apparent at faster walking speeds.

Greater than age-predicted functional deficits in older patients with primary hyperparathyroidism.

OBJECTIVE: To compare the functional capacity of "asymptomatic" patients with primary hyperparathyroidism (PHPT) with normative values of healthy age-matched subjects. METHODS: Eighteen asymptomatic patients with PHPT met the study inclusion criteria: age >55 years, serum calcium concentration elevated ≤1 mg/dL above normal, inappropriate elevation of parathyroid hormone (PTH) level, and no objective symptoms of PHPT. Functional capacity was assessed by (1) a 6-minute walk test, (2) time to complete 2 sit-to-stand maneuvers, (3) gait velocity, and (4) forward reach. Serum calcium, 25-hydroxyvitamin D, and PTH levels were measured by standard laboratory assays. Functional outcomes of the study patients were compared with age-matched normative values (unpaired t test) and correlated with these biomarkers. Because these patients often have weakness, fatigue, and malaise, we hypothesized that their functional capacity would be compromised relative to that of healthy, age-matched persons. RESULTS: The mean age of the patients was 65.6 years, and the mean serum calcium, PTH, and 25-hydroxyvitamin D levels (and standard deviations) were 10.36 ± 0.37 mg/dL, 122.22 ± 39.54 pg/mL, and 44.4 ± 14.27 ng/mL, respectively. Relative to normative values of healthy, age-matched subjects, these patients had comparable 6-minute walk distances but required a 37% longer time to complete a repeated sit-to-stand maneuver (P<.05), demonstrated a 52% slower gait speed (P<.001), and had a greater forward reach (P=.05). CONCLUSION: Our findings suggest that older asymptomatic patients with PHPT may have significant functional deficits that can affect their safety and quality of life. Therefore, their functional capacity should be routinely evaluated, and identified deficits should be treated with appropriate interventions.

Physical activity among adult survivors of childhood lower-extremity sarcoma.

INTRODUCTION: Adult survivors of childhood lower-extremity sarcoma are largely physically inactive, a behavior which potentially compounds their health burden. Altering this behavior requires understanding those factors that contribute to their physical inactivity. Therefore, this investigation sought to identify factors associated with inactivity in this subpopulation of cancer survivors. METHODS: Demographic, personal, treatment, and physical activity information from adult survivors of childhood lower-extremity sarcomas was obtained from the Childhood Cancer Survivor Study (CCSS) cohort. Generalized linear models were used to identify variables that best identified those individuals who were physically inactive. RESULTS: Only 41% of survivors met Center for Disease Control (CDC) activity guidelines. Survivors were 1.20 (95% confidence intervals (CI) 1.11-1.30) more likely compared to CCSS sibling cohort and 1.12 (95% CI 1.10-1.15) times more likely than the general population to fail to meet CDC guidelines. Significant predictors of physical inactivity included female sex, hemipelvectomy surgery, and platinum and vinca alkaloid chemotherapy. CONCLUSIONS: The primary findings of this study are that survivors of childhood onset lower-extremity sarcoma are (1) highly likely to be physically inactive and (2) less likely than their siblings or the general population to regularly exercise. This study has identified treatment-related risk factors associated with inactivity that will help health and wellness practitioners develop successful exercise interventions to help these survivors achieve recommended levels of physical activity for health. IMPLICATIONS FOR CANCER SURVIVORS: These results suggest that physical activity interventions for adult survivors of childhood lower-extremity sarcomas should be sex specific and responsive to unique physical late effects experienced by these survivors.

Robot assisted transaxillary surgery (RATS) for the removal of thyroid and parathyroid glands.

BACKGROUND: Robotic assisted transaxillary surgery (RATS) is a minimally invasive approach for the removal of the thyroid and/or parathyroid glands through the axilla. This anatomically directed technique, popularized by Chung, eliminates a visible scar and affords excellent high definition optics of the cervical anatomy. We report an initial series of single access RATS in the U.S. METHODS: The prospective endocrine surgery database at a tertiary care center was used to capture all patients who underwent RATS between October 2009 and March 2010. All procedures were performed using a single transaxillary incision. RESULTS: Fourteen operations were performed on 13 patients. Indications for RATS were indeterminate thyroid nodules in 11 patients, the need for completion thyroidectomy in 1 patient, and primary hyperparathyroidism in 2 patients. For patients who underwent robotic assisted thyroid lobectomy, the median thyroid nodule size was 2.1 cm (range, 0.8-2.8 cm), and the median body mass index was 25.33 (range, 21.3-34.4). Mean and median total operative times for robotic assisted thyroid lobectomies were 142 minutes and 137 minutes respectively (range, 113-192 minutes). Operative time for the 2 patients who underwent robotic assisted parathyroidectomy was 115 and 102 minutes. Minor complications occurred in 4 patients (28.5%), with no significant perioperative morbidity or mortality. CONCLUSION: RATS is feasible. We believe that further study of the RATS technique for removing thyroid lobes and parathyroid glands is warranted. This initial series suggests that careful, continued investigation is necessary prior to routine implementation into clinical practice across the U.S.
