Replacing sedentary time with physical activity and sleep: associations with quality of life in kidney cancer survivors.

PURPOSE: Kidney cancer survivors spend large quantities of time sedentary and little time physically active, which negatively impacts quality of life (QoL). This study examined (1) the association of reallocating sedentary time to sleep, light physical activity (PA), or moderate-to-vigorous PA (MVPA) on QoL in kidney cancer survivors and (2) the threshold at which results are clinically meaningful. METHODS: Kidney cancer survivors (N = 463) completed a survey including the Godin Leisure-Time Exercise Questionnaire, sitting time, sleep duration, and Functional Assessment of Cancer Therapy (FACT) scales. Isotemporal substitution analyses estimated associations of reallocating sedentary time to PA and sleep on QoL. RESULTS: Reallocating 10 min/day of sedentary time to MVPA was significantly associated with higher scores on the Trial Outcome Index-Fatigue (B = 0.60, SE = 0.25, p = 0.02), FACT-Fatigue (B = 0.71, SE = 0.32, p = 0.03), functional well-being (B = 0.18, SE = 0.08, p = 0.02), and fatigue subscales (B = 0.35, SE = 0.15, p = 0.02). Reallocating sedentary time to sleep was significantly associated with higher FACT-General (B = 0.15, SE = 0.08, p = 0.04) and functional well-being subscale (B = 0.06, SE = 0.03, p = 0.049) scores. Reallocating sedentary time to light PA was significantly associated with higher fatigue subscale scores (B = 0.46, SE = 0.23, p = 0.045). Kidney cancer survivors would need to reallocate a minimum of about 83, 200, and 65 min/day of MVPA, sleep, and light PA, respectively, for associations to be clinically meaningful. CONCLUSIONS: Reallocating sedentary time to MVPA, light PA, or sleep at higher doses is associated with better fatigue and physical aspects of QoL. Interventions should consider replacing sedentary time with MVPA or light PA in a gradual manner, and improve sleep quality for kidney cancer survivors.

Demographic, medical, social-cognitive, and environmental correlates of meeting independent and combined physical activity guidelines in kidney cancer survivors.

PURPOSE: Guidelines for cancer survivors recommend both aerobic physical activity (PA) and strength training (ST). Few kidney cancer survivors (KCS) are meeting single-activity or combined guidelines; therefore, examining factors influencing PA participation is warranted. The purpose of this study is to examine demographic, medical, social-cognitive, and environmental correlates of meeting independent (i.e., aerobic-only, strength training (ST)-only) and combined guidelines (i.e., aerobic and ST) in KCS. METHODS: KCS (N = 651) completed self-reported measures of PA and demographic, medical, social-cognitive, and perceived environmental factors. Built environment was assessed using the geographic information systems (GIS). Multinomial logistic regressions were conducted to determine the correlates of meeting the combined versus independent guidelines. RESULTS: Compared with meeting neither guideline, meeting aerobic-only guidelines was associated with higher intentions (p < .01) and planning (p < .01); meeting ST-only guidelines was associated with higher intentions (p = .02) and planning (p < .01), lower perceived behavioral control (PBC) (p = .03), healthy weight (p = .01), and older age (p < .01); and meeting the combined guidelines were associated with higher intentions (p < .01), planning (p = .02), higher instrumental attitudes (p < .01), higher education (p = .04), better health (p < .01), and localized cancer (p = .05). Additionally, compared with neither guideline, meeting aerobic-only (p < .01) and combined (p < .01) guidelines was significantly associated with access to workout attire. Compared with neither guideline, meeting aerobic-only guidelines was associated with proximity to retail (p = .02). CONCLUSION: PA participation correlates may vary based on the modality of interest. Interventions may differ depending on the modality promoted and whether KCS are already meeting single-modality guidelines.

Neurocognitive outcomes in long-term survivors of Wilms tumor: a report from the St. Jude Lifetime Cohort.

PURPOSE: To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT). METHODS: One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.1] years) and 354 community controls (55.6% female; 35 [10.2] years) completed comprehensive neuropsychological testing and physical examination, including echocardiography/electrocardiography, pulmonary function tests, and endocrine evaluation. Self-report of emotional distress, HRQOL, and social attainment were collected. Impairment was defined in relation to both controls and normative data. Generalized linear models were developed to examine impact of treatment and chronic health conditions on outcomes. RESULTS: WT survivors performed poorer than norms and controls in 6 of 16 cognitive variables and 1 of 8 HRQOL variables, with scores ranging from - 0.64 (mathematics) to - 0.21 (verbal fluency) standard deviations below expectations. Compared to controls, WT survivors were less likely to graduate college (odds ratio 2.23, 95% confidence interval 1.46-3.41) and had more moderate to severe neurologic conditions (18.4% vs 8.2%, p < 0.001), which were associated with poor memory (ß = - 0.90, p < 0.001), attention (ß = - 1.02, p < 0.001), and HRQOL general health (ß = - 0.80, p = 0.0015). Treatment variables and cardiopulmonary morbidity (higher in survivors) were not associated with outcomes. CONCLUSIONS: Survivors of WT demonstrate impairment in neurocognitive function and have lower social attainment during adulthood, with poorer neurocognitive function associated with neurologic morbidity. IMPLICATIONS FOR CANCER SURVIVORS: Survivors of WT should be offered neurocognitive evaluations and rehabilitation. Neurologic conditions should be routinely assessed, and appropriate support offered to reduce risk for functional limitations.

Modality-specific exercise guidelines and quality of life in kidney cancer survivors: A cross-sectional study.

OBJECTIVES: Few exercise oncology trials have compared aerobic with strength exercise or compared combined exercise (ie, aerobic and strength training) with aerobic only or strength only. It is unknown what single or combined exercise modality is optimal for quality of life (QoL) in cancer survivors. The purpose of this study is to estimate the prevalence of meeting the combined and independent aerobic and strength exercise guidelines in kidney cancer survivors (KCS) and determine any associations with QoL. METHODS: One thousand nine hundred eighty-five KCS were identified through a provincial registry in Canada and mailed a survey including exercise and QoL scales. RESULTS: Completed surveys were received from 703 KCS. Only 10.1% of KCS reported meeting the combined exercise guidelines. Analyses of covariance indicated that, for most QoL outcomes (eg, Functional Assessment of Cancer Therapy-General and Functional Assessment of Cancer Therapy-Fatigue), meeting the combined exercise guideline was superior to meeting either single modality guideline that, in turn, were superior to meeting neither guideline. For the primary outcome of the Trial Outcome Index-Fatigue, meeting the combined exercise guideline was superior to meeting (a) neither guideline (P < 0.001), (b) the strength-only guideline (P = 0.021), and (c) the aerobic-only guideline (P = 0.051). In turn, the aerobic and strength exercise only guidelines were superior to meeting neither guideline (P < 0.001 for aerobic; P = 0.045 for strength) but were not different from each other (P = 0.50). CONCLUSIONS: Meeting the combined exercise guideline has favorable associations with QoL in KCS, however, very few KCS are meeting the combined guideline.

The Long-Term Survival of a Patient With Stage IV Renal Cell Carcinoma Following an Integrative Treatment Approach Including the Intravenous α-Lipoic Acid/Low-Dose Naltrexone Protocol.

In this case report, we describe the treatment of a 64-year-old male patient diagnosed with metastatic renal cell carcinoma (RCC) in June of 2008. In spite of a left nephrectomy and the standard oncological protocols, the patient developed a solitary left lung metastasis that continued to grow. He was informed that given his diagnosis and poor response to conventional therapy, any further treatment would, at best, be palliative. The patient arrived at the Integrative Medical Center of New Mexico in August of 2010. He was in very poor health, weak, and cachectic. An integrative program-developed by one of the authors using intravenous (IV) α-lipoic acid, IV vitamin C, low-dose naltrexone, and hydroxycitrate, and a healthy life style program-was initiated. From August 2010 to August 2015, the patient's RCC with left lung metastasis was followed closely using computed tomography and positron emission tomography/computed tomography imaging. His most recent positron emission tomography scan demonstrated no residual increased glucose uptake in his left lung. After only a few treatments of IV α-lipoic acid and IV vitamin C, his symptoms began to improve, and the patient regained his baseline weight. His energy and outlook improved, and he returned to work. The patient had stable disease with disappearance of the signs and symptoms of stage IV RCC, a full 9 years following diagnosis, with a gentle integrative program, which is essentially free of side effects. As of November 2017 the patient feels well and is working at his full-time job.

Caregivers' information needs and their 'experiences of care' during treatment are associated with elevated anxiety and depression: a cross-sectional study of the caregivers of renal cancer survivors.

PURPOSE: This study aims to examine the unmet needs and psychological distress (anxiety and depression) in family caregivers of renal cell carcinoma survivors. METHODS: A cross-sectional study design was used. Unmet needs were assessed with the Supportive Care Needs Survey-Partners and Caregivers (SCNS-P&C) questionnaire, and psychological distress was measured with the Hospital Anxiety and Depression Scale (HADS) in a telephone survey of 196 caregivers of renal cell carcinoma (RCC) survivors. Chi-square tests examined bivariate relationships, and multivariate logistic regression examined the associations between anxiety and depression and of unmet needs with caregivers' experience of patients' care, time spent caregiving, caregivers' demographic characteristics and patients' disease stage. RESULTS: Sixty-four percent of caregivers had at least one low, moderate or high unmet need, with 53 % reporting at least three needs and 29 % reporting 10 or more unmet needs (median 2, range 0-38). Elevated anxiety (HADS-A > 8) and depression (HADS-D > 8) were found in 29 and 11 % of the sample, respectively. Psychological and emotional needs were associated with advanced cancer stage (stages 3 and 4) (OR 3.07, 95 % CI 1.35-6.76) and with experience of care during surgery (OR 0.87, 95 % CI 0.78-0.99). Healthcare service needs were associated with time spent caregiving, with caregivers spending >1 h/day in the past week having three times higher odds (OR 3.44, 95 % CI 1.52-7.72) than those not spending any time. Odds of experiencing information needs were lower in caregivers who were in a relationship (OR 0.20, 95 % CI 0.04-0.83). Elevated anxiety (OR 1.59, 95 % CI 1.09-2.33) and depression (OR 2.02, 95 % CI 1.08-3.79) were associated with unmet information needs. Depression was also associated with experiences of care during treatment (OR 0.69, 95 % CI 0.49-0.96). CONCLUSION: RCC caregivers' unmet information needs are associated with elevated anxiety and depression. Improved experiences of cancer care are associated with lower odds of unmet needs and elevated depression in RCC caregivers.

Reconsidering Physical Activity Restrictions for Mononephric Survivors of Childhood Cancer: A Report From the Children's Oncology Group.

Although traditional recommendations for mononephric childhood cancer survivors are to avoid contact sports in order to protect the remaining kidney, review of available evidence suggests that the majority of renal loss is caused by accidents not involving sports. An interdisciplinary team performed a review of the English literature published from 1999 to 2012 within the PubMed, Cochrane, Google Scholar, and National Guidelines Clearinghouse databases. The level of evidence and proposed recommendations were graded according to an established rubric and GRADE criteria. Our review found that kidney loss is most commonly caused by nonsports activities such as motor vehicle accidents and falls, implying that restrictions on sports-related activity in mononephric pediatric survivors are not well supported. This favors encouraging ordinary sports and related activities without restriction in mononephric childhood cancer survivors because the known benefits of exercise outweigh the exceedingly low risk of renal loss. Accordingly, activity recommendations for mononephric patients have been revised in the most current version of the Children's Oncology Group Long-term Follow-Up Guidelines for Survivors of Childhood, Adolescent and Young Adult Cancers. This has important implications for this and similar populations who may now undertake individual and organized sports without undue regard for their mononephric status.

Social-ecological correlates of physical activity in kidney cancer survivors.

PURPOSE: Previous studies in cancer survivors have examined behavioral correlates of physical activity (PA), but no study to date has adopted a broader social-ecological framework in understanding PA. This study examined the associations among demographic, medical, social-cognitive, and environmental correlates of meeting PA guidelines among kidney cancer survivors (KCS). METHODS: All 1985 KCS diagnosed between 1996 and 2010 identified through a Canadian provincial registry were mailed a survey that consisted of medical, demographic, and social-cognitive measures, as well as PA as measured by the Godin Leisure Time Exercise Questionnaire. Environmental constructs were also assessed for both self-report and objective measures using geographic information systems (GIS). A series of binary logistic regression analyses were conducted in this cross-sectional study. RESULTS: Completed surveys with geographical information were received from 432 KCS with M age = 64.4 ± 11.1 years, 63.2 % male, and 82.2 % having localized kidney cancer. In the final multivariate model, meeting PA guidelines was associated with disease stage (OR = 0.25, p = .005), having drug therapy (OR = 3.98, p = .009), higher levels of instrumental attitudes (OR = 1.66, p = .053), higher levels of intention (OR = 1.72, p = .002), and the perceived presence of many retail shops in the neighborhood (OR = 1.37, p = .032). CONCLUSIONS: Meeting PA guidelines in KCS were associated with various aspects of the social-ecological model. IMPLICATIONS FOR CANCER SURVIVORS: Understanding the social-ecological correlates for PA can provide insight into future interventions designed to increase PA in KCS. Prime targets for PA promotion should consider treatment-related factors, promote the benefits of PA, and enhance positive perceptions of the built environment.

Physical activity preferences in a population-based sample of kidney cancer survivors.

PURPOSE: Physical activity (PA) improves quality of life in kidney cancer survivors (KCS), but PA participation rates are low. Behavior change interventions to increase PA in KCS should take into account PA preferences. The purpose of this study was to identify the PA preferences of KCS and determine any associations with selected demographic and medical variables. METHODS: All 1,985 KCS diagnosed between 1996 and 2010 identified through a Canadian provincial registry in Alberta, Canada were mailed a survey that consisted of the Godin Leisure-Time Exercise Questionnaire and various PA preference variables. Standard demographic and medical variables were also collected. RESULTS: Completed surveys were received from 703 of 1,654 (43%) eligible KCS. Over 80% of KCS felt they were able or may be able to participate in a PA program designed for KCS and over 70% were interested or may be interested in doing so. The most common PA preferences were to receive PA information from a fitness expert at a cancer center (55.7%), receive information via print material (50.0%), start a PA program after treatment (36.5%), exercise with a spouse (39.6%), exercise at home (52.0%), do moderate-intensity PA (58.4%), and walk in both the summer (69.4%) and winter (48.2%). Chi-square analyses uncovered that age, sex, and current PA were the personal variables most consistently associated with PA preferences. CONCLUSION: The majority of KCS expressed an interest in doing a PA program and important preferences were identified. These preferences may be used to inform PA interventions to enhance motivation and adherence in KCS.

Modelled cost-effectiveness of high cut-off haemodialysis compared to standard haemodialysis in the management of myeloma kidney.

BACKGROUND: Approximately 10-20% of multiple myeloma patients experience dialysis-dependent renal failure. This is principally due to myeloma kidney, a tubulointerstitial injury caused by high circulating concentrations of monoclonal free light chains. Studies have found that between 3% and 37% of patients with myeloma kidney requiring dialysis recover renal function. In-vivo studies indicate that extended haemodialysis using high cut-off dialysers (HCO-HD) can remove significant quantities of free light chains and is associated with a renal recovery rate of 63-74% in these patients. OBJECTIVE: The objective of this study was to assess the cost-effectiveness of HCO-HD compared to standard HD in the management of myeloma kidney. METHODS: The study used a lifetime Excel-based decision tree model that followed all patients from treatment of the initial presentation with myeloma kidney requiring dialysis to death. It was populated with published clinical data, United Kingdom costs and expert opinion, using a National Health Service perspective and 3.5% annual discounting. RESULTS: HCO-HD was dominant to standard HD, meaning it was both more effective (greater life years and quality adjusted life years) and less costly, due to a greater increase in the proportion of patients recovering renal function. The model projected lifetime costs of £31,345 per patient for patients treated with standard haemodialysis only and £24,845 for the new treatment (discounted). The model predicted an average survival of 19.92 months for patients on standard HD and 33.90 months for the new therapy (discounted). CONCLUSIONS: The analysis found that treatment of myeloma kidney using an extended schedule of HCO-HD may substantially improve renal recovery in multiple myeloma patients compared to standard HD, resulting in greater life expectancy and cost savings due to avoided chronic dialysis. Limitations of the study include those common to rare diseases including small study sizes and limited natural history data.

The mechanism of local tumor irradiation combined with interleukin 2 therapy in murine renal carcinoma: histological evaluation of pulmonary metastases.

We have demonstrated that tumor irradiation enhanced the therapeutic effect of interleukin 2 (IL-2) on pulmonary metastases from a murine renal adenocarcinoma, Renca. To investigate the mechanism of interaction between tumor irradiation and IL-2 therapy, we have histologically evaluated the effects of each therapy alone or in combination on Renca pulmonary metastases. Following treatment of established lung metastases with irradiation and IL-2 therapy, lung sections were processed for H&E or immunohistochemical staining. We found that tumor irradiation or IL-2 therapy locally induced vascular damage, resulting in multifocal hemorrhages and mononuclear cell mobilization in the lung tissue. This effect was amplified in lungs treated with the combined therapy. Immunohistochemistry showed that irradiation produced a macrophage influx into irradiated tumor nodules, and systemic IL-2 therapy induced T-cell infiltration in tumor nodules. Lungs treated with the combined therapy exhibited massive macrophage, T-cell, and natural killer cell mobilization in disintegrating tumor nodules and in the lung tissue. This combined therapy caused a decrease in the number of proliferating tumor cells and an increase in the number of apoptotic cells, which were more marked than with either therapy alone. We suggest that the macrophages mobilized by radiation-induced tissue injury could play a role in phagocytosis of apoptotic tumor cells, processing and presenting of tumor antigens for a systemic immune response activated by IL-2. Tumor destruction may result from the concomitant action of activated T cells, natural killer cells, and macrophages infiltrating the tumor nodules.
