Hammond ST, Baumfalk DR, Parr SK, Butenas AL, Scheuermann BC, Turpin VRG, Behnke BJ, Hashmi MH, Ade CJ. Impaired microvascular reactivity in patients treated with 5-fluorouracil chemotherapy regimens: Potential role of endothelial dysfunction. IJC HEART & VASCULATURE 2023; 49:101300. [PMID: 38173789 PMCID: PMC10761309 DOI: 10.1016/j.ijcha.2023.101300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 10/27/2023] [Accepted: 11/06/2023] [Indexed: 01/05/2024]
Abstract
Background 5-fluorouracil (5-FU) is the second most common cancer chemotherapy associated with short- and long-term cardiotoxicity. Although the mechanisms mediating these toxicities are not well understood, patients often present with symptoms suggestive of microvascular dysfunction. We tested the hypotheses that patients undergoing cancer treatment with 5-FU based chemotherapy regimens would present with impaired microvascular reactivity and that these findings would be substantiated by decrements in endothelial nitric oxide synthase (eNOS) gene expression in 5-FU treated human coronary artery endothelial cells (HCAEC). Methods We first performed a cross-sectional analysis of 30 patients undergoing 5-FU based chemotherapy treatment for cancer (5-FU) and 32 controls (CON) matched for age, sex, body mass index, and prior health history (excluding cancer). Cutaneous microvascular reactivity was evaluated by laser Doppler flowmetry in response to endothelium-dependent (local skin heating; acetylcholine iontophoresis, ACh) and -independent (sodium nitroprusside iontophoresis, SNP) stimuli. In vitro experiments in HCAEC were completed to assess the effects of 5-FU on eNOS gene expression. Results 5-FU presented with diminished microvascular reactivity following eNOS-dependent local heating compared to CON (P = 0.001). Iontophoresis of the eNOS inhibitor L-NAME failed to alter the heating response in 5-FU (P = 0.95), despite significant reductions in CON (P = 0.03). These findings were corroborated by lower eNOS gene expression in 5-FU treated HCAEC (P < 0.01) compared to control. Peak vasodilation to ACh (P = 0.58) nor SNP (P = 0.39) were different between groups. Conclusions The present findings suggest diminished microvascular function along the eNOS-NO vasodilatory pathway in patients with cancer undergoing treatment with 5-FU-based chemotherapy regimens and thus, may provide insight into the underlying mechanisms of 5-FU cardiotoxicity.

Abstract
Dose limiting cardiotoxicity remains a major limiting factor in the clinical use of several cancer chemotherapeutics including anthracyclines and the antimetabolite 5-fluorouracil (5-FU). Prior work has demonstrated that chemotherapeutics increase expression of R7 family regulator of G protein signaling (RGS) protein-binding partner Gβ5, which drives myocyte cytotoxicity. However, though several R7 family members are expressed in heart, the exact role of each protein in chemotherapy driven heart damage remains unclear. Here, we demonstrate that RGS11, downregulated in the human heart following chemotherapy exposure, possesses potent anti-apoptotic actions, in direct opposition to the actions of fellow R7 family member RGS6. RGS11 forms a direct complex with the apoptotic kinase CaMKII and stress responsive transcription factor ATF3 and acts to counterbalance the ability of CaMKII and ATF3 to trigger oxidative stress, mitochondrial dysfunction, cell death, and release of the cardiokine neuregulin-1 (NRG1), which mediates pathological intercommunication between myocytes and endothelial cells. Doxorubicin triggers RGS11 depletion in the murine myocardium, and cardiac-specific OE of RGS11 decreases doxorubicin-induced fibrosis, myocyte hypertrophy, apoptosis, oxidative stress, and cell loss and aids in the maintenance of left ventricular function. Conversely, RGS11 knockdown in heart promotes cardiac fibrosis associated with CaMKII activation and ATF3/NRG1 induction. Indeed, inhibition of CaMKII largely prevents the fibrotic remodeling resulting from cardiac RGS11 depletion underscoring the functional importance of the RGS11-CaMKII interaction in the pathogenesis of cardiac fibrosis. These data describe an entirely new role for RGS11 in heart and identify RGS11 as a potential new target for amelioration of chemotherapy-induced cardiotoxicity.

VASCULAR BIOLOGY (BRISTOL, ENGLAND) 2021; 3:R106-R120. [PMID: 34870095 PMCID: PMC8630759 DOI: 10.1530/vb-21-0013] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Accepted: 10/18/2021] [Indexed: 06/02/2023]
Abstract
Breast cancer chemotherapy, although very potent against tumour tissue, results in significant cardiovascular toxicity. The focus of research in this area has been predominantly towards cardiotoxicity. There is limited evidence detailing the impact of such treatment on the vasculature despite its central importance within the cardiovascular system and resultant detrimental effects of damage and dysfunction. This review highlights the impact of chemotherapy for breast cancer on the vascular endothelium. We consider the most likely mechanisms of endothelial toxicity to be through direct damage and dysfunction of the endothelium. There are sharp consequences of these detrimental effects as they can lead to cardiovascular disease. However, there is potential for exercise to alleviate some of the vascular toxicity of chemotherapy, and the evidence for this is provided. The potential role of exercise in protecting against vascular toxicity is explained, highlighting the recent in-human and animal model exercise interventions. Lastly, the mediating mechanisms of exercise protection of endothelial health is discussed, focusing on the importance of exercise for endothelial health, function, repair, inflammation and hyperlipidaemia, angiogenesis, and vascular remodelling. These are all important counteracting measures against chemotherapy-induced toxicity and are discussed in detail.

Chemotherapy-induced peripheral neuropathy is promoted by enhanced spinal insulin-like growth factor-1 levels via astrocyte-dependent mechanisms. Brain Res Bull 2021; 175:205-212. [PMID: 34333050 DOI: 10.1016/j.brainresbull.2021.07.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/19/2021] [Accepted: 07/27/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND Chemotherapy-induced peripheral neuropathy (CIPN) is a common and intractable complication in chemotherapy-receiving patients. Insulin-like growth factor-1 (IGF-1) is a popular neurotrophin with various functions, such as maintaining neuronal survival and synaptic functioning in the central nervous system. Therefore, we hypothesized that the IGF-1 signaling pathway could be a candidate target for treating CIPN. METHODS We established the CIPN model by injecting mice intraperitoneally with oxaliplatin and assessed IGF-1 protein expression, its receptor IGF1R, phospho-IGF1R (p-IGF1R), interleukin-17A (IL-17A), tumor necrosis factor-α (TNF-α), and calcitonin gene-related peptide (CGRP) in the lumbar spinal cord with Western blot and immunofluorescence. To examine the effect of IGF-1 signaling on CIPN, we injected mice intrathecally or intraperitoneally with mouse recombinant IGF-1 (rIGF-1). RESULTS IGF-1 protein expression decreased significantly in the spinal cord on D3 and D10 (the 3rd and 10th days after beginning oxaliplatin chemotherapy) and was co-localized with astrocytes primarily in the lumbar spinal cord, whereas IGF1R was predominantly expressed on neurons. Both intrathecally- and intraperitoneally-administered rIGF-1 relieved the chemotherapy-induced pain-like behavior and reduced IL-17A, TNF-α, and CGRP protein expressions in the spinal cord. CONCLUSION Our results indicate a vital role for IGF-1 signaling in CIPN. Targeting IGF-1 signaling could be a potent therapeutic strategy for treating CIPN in clinical settings.

Abstract
Paracetamol (PAR) is the most frequently consumed non-prescription drug, yet it is well known to induce toxicity. Here, we have evaluated the effects of exercise training on vascular dysfunction induced by PAR. Rats were distributed among four groups: (a) Sedentary; (b) Exercise; (c) Sedentary+PAR; and (d) Exercise+PAR. The exercise comprised swimming 50 min/d, 5 d/wk for 6 weeks (+PAR in the last 2 weeks, at 400 mg/kg/d/p.o.). After killing, the rats' blood and aortas were collected for biochemical analysis of hepatic transaminases, TBARs reaction, glutathione, glutathione reductase, SOD, and catalase. In vitro vascular relaxation was measured using acetylcholine and sodium nitroprusside in the presence or absence of tiron (an antioxidant). Vascular protein expression (eNOS and sGC) also were analysed. Increased transaminases after PAR treatment were found to be reduced by exercise. Vasodilation was impaired by PAR only in the sedentary group. Exercise prevented alterations in lipoperoxidation and glutathione levels after PAR exposure. Glutaathione reductase and SOD also were increased by PAR but were normalized in the exercised group. Catalase activity and protein expressions did not change in any group. PAR treatment caused impairment in both vasodilation and redox balance; however, exercise training prevented the vascular and redox system dysfunction induced by PAR treatment.

Abstract
OPINION STATEMENT Fluoropyrimidine (FP) is used to treat a wide range of cancers; however, it is associated with drug-induced vascular toxicity, as well as angina pectoris and coronary spasm. FP has been administered for many years, although the incidence, mechanisms, and appropriate methods for managing its associated cardiovascular toxicities have not been clarified, and the management of these complications has not been standardized. This lack of evidence is not limited to FP. Many trials of anticancer agents have been conducted, excluding patients with heart diseases. Hence, there is a paucity of epidemiological data on cardiovascular adverse events caused by anticancer agents. There have been remarkable improvements in cancer treatment in recent years, with consequent improvements in prognosis. In this context, new cardiovascular toxicities related to new drugs have emerged. We are now compelled to respond to cardiovascular adverse events despite the lack of evidence regarding optimal management. The result has been establishment and rapid maturation of the new academic field of cardio-oncology. Despite the relative lack of evidence, we must review small pieces of evidence that have accumulated to date and make the utmost efforts to provide patients with effective evidence-based medical care. Simultaneously, we urgently need randomized clinical trials to build strong evidence.

Abstract
Fluoropyrimidines are chemotherapeutic agents that confer great benefit to many patients with solid tumors, but their use is often limited by cardiotoxicity. The incidence and precise mechanisms of cardiotoxicity remain uncertain. Clinical presentations of fluoropyrimidine toxicity are varied and include chest pain, myocardial infarction, acute cardiomyopathy, arrhythmia, cardiogenic shock, and sudden cardiac death. Proposed mechanisms include coronary vasospasm, coronary endothelial dysfunction, direct myocardial toxicity, myocarditis, and Takotsubo cardiomyopathy. Therapeutic and prophylactic interventions primarily target coronary vasospasm as the underlying cause. Prospective studies are needed to develop evidence-based approaches to cardioprotection in patients receiving fluoropyrimidines.

Abstract
Cardiovascular disease and cancer are leading contributors to the global disease burden. As a result of cancer therapy-related cardiotoxicities, cardiovascular disease results in significant morbidity and mortality in cancer survivors and patients with active cancer. There is an unmet need for management of cardio-oncology conditions, which is predicted to reach epidemic proportions, and better understanding of their pathophysiology and treatment is urgently required. The proposed mechanisms underlying cardiotoxicity induced by 5-fluorouracil (5-FU) are vascular endothelial damage followed by thrombus formation, ischaemia secondary to coronary artery vasospasm, direct toxicity on myocardium and thrombogenicity. In patients with angina and electrocardiographic evidence of myocardial ischaemia due to chemotherapy-related coronary artery vasospasm, termination of chemotherapy and administration of calcium channel blockers or nitrates can improve ischaemic symptoms. However, coronary artery vasospasm can reoccur with 5-FU re-administration with limited effectiveness of vasodilator prophylaxis observed. While pre-existing coronary artery disease may increase the ischaemic potential of 5-FU, cardiovascular risk factors do not appear to completely predict the development of cardiac complications. Pharmacogenomic studies and genetic profiling may help predict the occurrence and streamline the treatment of 5-FU-induced coronary artery vasospasm. Echocardiographic measures such as the Tei index may help detect subclinical 5-FU cardiotoxicity. Further research is required to explore the cardioprotective effect of agents such as coenzyme complex, GLP-1 analogues and degradation inhibitors on 5-FU-induced coronary artery vasospasm.

Abstract
Thanks to increasingly effective treatment, breast cancer mortality rates have significantly declined over the past few decades. Following the increase in life expectancy of women diagnosed with breast cancer, it has been recognized that these women are at an elevated risk for cardiovascular disease due in part to the cardiotoxic side effects of treatment. This paper reviews evidence for the role of exercise in prevention of cardiovascular toxicity associated with chemotherapy used in breast cancer, and in modifying cardiovascular risk factors in breast cancer survivors. There is growing evidence indicating that the primary mechanism for this protective effect appears to be improved antioxidant capacity in the heart and vasculature and subsequent reduction of treatment-related oxidative stress in these structures. Further clinical research is needed to determine whether exercise is a feasible and effective nonpharmacological treatment to reduce cardiovascular morbidity and mortality in breast cancer survivors, to identify the cancer therapies for which it is effective, and to determine the optimal exercise dose. Safe and noninvasive measures that are sensitive to changes in cardiovascular function are required to answer these questions in patient populations. Cardiac strain, endothelial function, and cardiac biomarkers are suggested outcome measures for clinical research in this field.

Abstract
Studying human vascular disease in conventional cell cultures and in animal models does not effectively mimic the complex vascular microenvironment and may not accurately predict vascular responses in humans. We utilized a microfluidic device to recapitulate both shear stress and O2 levels in health and disease, establishing a microfluidic vascular model (μVM). Maintaining human endothelial cells (ECs) in healthy-mimicking conditions resulted in conversion to a physiological phenotype namely cell elongation, reduced proliferation, lowered angiogenic gene expression and formation of actin cortical rim and continuous barrier. We next examined the responses of the healthy μVM to a vasotoxic cancer drug, 5-Fluorouracil (5-FU), in comparison with an in vivo mouse model. We found that 5-FU does not induce apoptosis rather vascular hyperpermeability, which can be alleviated by Resveratrol treatment. This effect was confirmed by in vivo findings identifying a vasoprotecting strategy by the adjunct therapy of 5-FU with Resveratrol. The μVM of ischemic disease demonstrated the transition of ECs from a quiescent to an activated state, with higher proliferation rate, upregulation of angiogenic genes, and impaired barrier integrity. The μVM offers opportunities to study and predict human ECs with physiologically relevant phenotypes in healthy, pathological and drug-treated environments.

Abstract
Cancer-related fatigue is a pervasive syndrome experienced by a majority of cancer patients undergoing treatment, and muscular dysfunction may be a key component in the development and progression of this syndrome. Doxorubicin (DOX) is a commonly used antineoplastic agent used in the treatment of many cancers. The purpose of this study was to determine the effect of DOX exposure on the function of cardiac, skeletal, and smooth muscle tissues and examine the role accumulation of DOX may play in this process. In these studies, rats were treated with DOX and measurements of cardiac, skeletal, and smooth muscle function were assessed 1, 3, and 5 days after exposure. All muscular tissues showed significant and severe dysfunction, yet there was heterogeneity both in the time course of dysfunction and in the accumulation of DOX. Cardiac and skeletal muscle exhibited a time-dependent progressive decline in function during the 5 days following DOX treatment. In contrast, vascular function showed a decline in function that could be characterized as rapid onset and was sustained for the duration of the 5-day observation period. DOX accumulation was greatest in cardiac tissue, yet all muscular tissues showed a similar degree of dysfunction. Our data suggest that in muscular tissues both DOX-dependent and DOX-independent mechanisms may be involved with the muscular dysfunction observed following DOX treatment. Furthermore, this study highlights the fact that dysfunction of skeletal and smooth muscle may be an underappreciated aspect of DOX toxicity and may be a key component of cancer-related fatigue in these patients.

Abstract
AIM This study aimed to elucidate the influence of 5-fluorouracil (5-FU)-based therapy on the vascular endothelium and its association with 5-FU-induced heart ischemia. METHODS The study prospectively accrued patients (n = 106) having completely resected colorectal cancer and receiving adjuvant treatment with 5-FU, folinic acid, and oxaliplatin. The levels of plasma von Willebrand factor (vWf), urine albumin-to-creatinine ratio (UACR), coagulation factor II + VII + X, and fibrin D-dimer were serially assessed before, during, and after chemotherapy. RESULTS The vWf level increased from median (range) 1.43 kU/l (0.48 to >3) to 2.64 kU/l (0.23 to >3) (P = 0.001), the UACR increased from 1.1 ± 0.2 mg/mmol (mean ± SE) to 2.1 ± 0.3 mg/mmol (P = 0.001), the coagulation factor II + VII + X activity decreased from 1.00 ± 0.02 to 0.94 ± 0.02 U/l (P = 0.001), and the fibrin D-dimer level increased from 1.1 ± 0.2 to 2.1 ± 0.3 kU/l (P = 0.001) at baseline and during chemotherapy, respectively. The changes in the levels of vWf (P = 0.3), UACR (P = 0.8), coagulation factor II + VII + X (P = 0.8), and fibrin D-dimer (P = 0.6) in nine (8.5%) patients having clinical signs of cardiotoxicity were not significantly different from that of the patients not having cardiotoxicity. The 5-FU-induced rise in plasma biomarkers was not significantly related to the cardiovascular morbidity or its risk factors (P = 0.9). CONCLUSIONS 5-FU therapy induces global reversible endothelial injury leading to a procoagulant state. The ensuing endothelial dysfunction may be of significance to the pathogenesis of 5-FU-induced clinically overt cardiotoxicity. Cardiovascular disease is not significant for the vulnerability of the endothelium to 5-FU-based chemotherapy.

Abstract
PURPOSE/OBJECTIVES To investigate the effects of supervised exercise training on cardiopulmonary function and fatigue in cancer survivors undergoing various clinical treatments. DESIGN Pretest and post-test quasiexperimental. SETTING Outpatient oncology rehabilitation center. SAMPLE 96 breast cancer survivors undergoing various clinical treatments. METHODS Subjects were divided into four groups based on the specific type of clinical treatment: surgery alone (n = 22); surgery and chemotherapy (n = 30); surgery and radiation (n = 17); and surgery, chemotherapy, and radiation (n = 27). Following a comprehensive screening and medical examination, cardiovascular endurance, pulmonary function, and fatigue were assessed, leading to the development of an individualized exercise prescription and a six-month exercise intervention. Repeated-measures analysis of variance and covariance were used to compare the effectiveness of the intervention and differences among treatment groups. MAIN RESEARCH VARIABLES Systolic and diastolic blood pressure, resting heart rate, forced vital capacity, forced expiratory volume, predicted oxygen consumption, time on treadmill, and fatigue. FINDINGS Cardiopulmonary function (predicted maximal oxygen consumption and time on treadmill) significantly increased in all groups after exercise training. In addition, resting heart rate and forced vital capacity significantly improved in those receiving surgery, chemotherapy, and radiation. Psychologically, the exercise intervention resulted in significant reductions in behavioral, affective, sensory, cognitive and mood, and total fatigue scale scores in all three groups who received treatment with surgery. The breast cancer survivors in the surgery-alone group showed significant reductions in behavioral, affective, and total fatigue scale scores but not in sensory and cognitive and mood fatigue scale scores. CONCLUSIONS The results suggest that moderate intensity, individualized, prescriptive exercise maintains or improves cardiopulmonary function with concomitant reductions in fatigue regardless of treatment type. Moreover, cancer survivors receiving combination chemotherapy and radiotherapy following surgery appear to benefit to a greater extent as a result of an individualized exercise intervention. IMPLICATIONS FOR NURSING Clinicians need to be aware of adjuvant therapies such as moderate exercise that attenuate negative side effects of cancer treatments. Symptom management recommendations should be given to cancer survivors concerning the effectiveness of exercise throughout the cancer continuum and the importance of participating in a cancer rehabilitation exercise program.

Abstract
Over the past decade, therapies for several previously untreatable types of cancer have emerged or have improved; thus, more focus has been given to long-term complications of cancer therapy. The most commonly known cardiac toxicities of cancer therapy are cardiac dysfunction or congestive heart failure. Vascular complications--such as ischemia, myocardial infarction, venous or arterial thrombosis, and newly developed or worsened hypertension--are also relatively common following cancer treatment, particularly in patients with advanced-stage cancer. Experimental studies have suggested a number of potential mechanisms that might account for vascular complications of cancer therapies, which include dysfunction or damage of endothelial cells, increased platelet aggregation, and modulation of nitric oxide levels. This Review describes the vascular complications of treatment with 5-fluorouracil, bevacizumab, and several new tyrosine kinase inhibitors, with special emphasis on thrombotic complications and hypertension.

Abstract
UNLABELLED The clinical use of the chemotherapeutic drug doxorubicin (DOX) is limited due to a dose-dependent cardiotoxicity. Evidence is mounting that exercise protects against DOX-related cardiac dysfunction, and as such, it may be possible that prior endurance training promotes defense against DOX cardiotoxicity. PURPOSE To examine the effects of exercise preconditioning on acute DOX-induced cardiotoxicity, and to determine whether any observed cardioprotection was associated with myosin heavy chain (MHC) isoform alterations. METHODS Male Sprague-Dawley rats trained on a motorized treadmill, had access to voluntary running wheels, or remained sedentary for 10 wk prior to being injected with either saline or 10 mg.kg(-1) DOX. Left ventricular function was then assessed in vivo using transthoracic echocardiography and ex vivo using the isolated working heart at 5 and 10 d after injection. Additionally, left ventricular MHC isoform expression was analyzed as a possible mechanism to explain exercise-induced cardioprotection. RESULTS DOX treatment promoted significant in vivo and ex vivo cardiac dysfunction at 5 and 10 d after injection in sedentary animals, and this dysfunction was associated with an upregulation of the beta-MHC isoform. Exercise preconditioning protected against DOX-induced cardiac dysfunction at 5 and 10 d after injection by attenuating beta-MHC upregulation. CONCLUSION Endurance training prior to DOX treatment protects against acute DOX cardiotoxicity for up to 10 d, and this protection can potentially be explained by a preservation of MHC isoform distribution.

Abstract
This investigation determined the cardiopulmonary function and fatigue alterations in male cancer survivors during treatment as well as following treatment utilizing similar exercise assessment protocols and individualized, prescriptive exercise interventions. The study included 45 male cancer survivors that were referred by local oncologists. Following a comprehensive screening and physical examination, cardiovascular endurance, pulmonary function, and fatigue were assessed leading to the development of 12-week individualized exercise prescriptions and exercise interventions. The cancer survivors were divided into during treatment (DTm) and following treatment (FTm) groups. Repeated-measures analysis of variance and analyses of covariance were used to compare pre- versus postintervention and between groups. Cardiopulmonary function was maintained in the DTm, whereas the FTm showed significant reductions in resting heart rate (P < .05) with concurrent increases in predicted VO2max and time on treadmill ( P < .05) postexercise intervention. Fatigue levels did not increase in the DTm group, whereas the FTm group showed significant reductions in behavioral fatigue, affective fatigue, sensory fatigue, cognitive/mood fatigue, and total fatigue (P < .05) after the exercise intervention. The results of the current study suggest that moderate intensity, individualized, prescriptive exercise intervention maintains or improves cardiovascular and pulmonary function with concomitant reductions in fatigue in cancer survivors during and following cancer treatment. Exercise appears to be a safe, efficacious strategy for improving physical fitness in cancer survivors during and following treatment.

Abstract
BACKGROUND Cancer treatments have serious physiological and psychological side effects in cancer survivors. This investigation examined cardiopulmonary function and fatigue in breast cancer survivors during and after treatment by using similar exercise assessments, prescriptions, individualized interventions, and reassessments. METHODS The study included 113 women diagnosed with breast cancer. Participants were grouped according to whether they participated in an individualized prescriptive exercise program during cancer treatment (DTm) or after cancer treatment (FTm). After a comprehensive screening and medical examination, cardiovascular endurance, pulmonary function, and fatigue were assessed, which led to the development of an individualized 6-month exercise prescription and exercise intervention. Repeated-measures analysis of variance (ANOVA) and analyses of covariance (ANCOVA) were used to compare the effectiveness of the intervention and differences between groups. RESULTS Cardiopulmonary function (systolic blood pressure, time on treadmill) improved in the DTm group (P < .05), whereas the FTm group showed reductions in systolic and diastolic blood pressure and resting heart rate (P < .05) with concurrent increases in percentage of predicted FVC, % of predicted FEV(1), predicted VO(2)max, and time on treadmill (P < .05). Psychologically, the DTm group showed reductions in behavioral, sensory, and total fatigue (P < .05), whereas the FTm group showed reductions in behavioral, affective, sensory, cognitive/mood, and total fatigue (P < .05). CONCLUSIONS The current study suggested that moderate intensity, individualized, prescriptive exercise maintains or improves cardiovascular and pulmonary function with concomitant reductions in fatigue during and after cancer treatment. However, it is critical that exercise be individualized to specific needs of the cancer survivor to prevent exacerbation of cancer treatment toxicities.

Abstract
BACKGROUND Cancer survivors experience muscular weakness and reduced mobility, thereby compromising quality of life. This investigation utilized moderate prescriptive exercise to improve upper- and lower-body muscular fitness, flexibility, depression and quality of life in cancer patients. PATIENTS AND METHODS One hundred and thirty-five breast and prostate cancer survivors received cancer and medical history screening and a medical examination, as well as assessments of muscular strength (handgrip dynamometer) and endurance (bench press, lateral pull-down, leg press, shoulder press and curl-up crunch test), flexibility (Modified Sit and Reach), depression (Beck Depression Inventory) and quality of life (Quality of Life Index). Following the exercise assessments, cancer survivors trained in resistance exercise for 6 months during treatment or following treatment based on their results from the assessments and health status. RESULTS Cancer survivors following treatment showed significant (P = 0.006) improvements in upper-body muscular endurance (+46.8%), lower-body muscular endurance (+67.1%), core muscular endurance (+32.5%) and flexibility (+6.2%), with concomitant improvements (P = 0.013) in depression (-25.6%) and total quality of life (+7.2%). Cancer survivors during treatment showed significant (P = 0.012) improvements in upper-body muscular endurance (+79.1%) and lower-body muscular endurance (+49.7%) while maintaining core endurance and flexibility in conjunction with improvements (P = 0.022) in depression (-43.0%) and quality of life (+11.5%). CONCLUSIONS Moderate-intensity individualized prescriptive exercise is a safe and efficacious means to augment muscular function and improve the quality of life of cancer survivors.
